Abstract
Following the publication of the above article, an interested reader drew to the authors' attention that, in Fig. 1E on p. 1885, the STAT3 blots shown for the A549 and A2780 cell lines were strikingly similar, such that these data were possibly derived from the same original source where the panels were intended to show the results from differently performed experiments. Upon examining their original data, the authors have realized that an inadvertent error was made in assembling the data in the figure, and the STAT3 data shown correctly for the A549 cell line were erroneously copied across for the A2780 cell line. The corrected version of Fig. 1, showing the correct STAT3 blot for the A2780 cell line in Fig. 1E, is shown on the next page. Note that this error did not affect the overall conclusions reported in the paper. All the authors agree with the publication of this corrigendum, and are grateful to the Editor of Oncology Reports for allowing them the opportunity to publish this. They also apologize to the readership for any inconvenience caused. [Oncology Reports 39: 1883‑1891, 2018; DOI: 10.3892/or.2018.6232].

Abstract
The effect of Crocus sativus on several disorders has been discussed or even confirmed, but the efficacy of this herb on the female reproductive system has not been well presented. In this regard, this systematic review comprehensively discussed the efficacy of C. sativus and its main phytochemical compounds on the female reproductive system and its disorders for the first time. In this systematic review, scientific databases, including PubMed, Web of Sciences, Google Scholar, Scopus, and Scientific Information Database, were explored profoundly. In vivo, in vitro, and human studies published until the end of July 2023, which had investigated the pharmacological properties of C. sativus, crocin, crocetin, safranal, or picrocrocin on the female reproductive system, were selected. A total of 50 studies conducted on the effect of C. sativus on the female reproductive system were acquired. These studies confirmed the efficacy of C. sativus or its main phytochemical ingredients in several aspects of the female reproductive system, including regulation of sex hormones, folliculogenesis, ovulation, and protection of the ovary and uterus against several oxidative stress. Several retrieved studies indicated that this herb also can alleviate the symptoms of patients suffering from dysmenorrhea, premenstrual syndrome, menopause, polycystic ovary disease (PCOD), and sexual dysfunction. Furthermore, it is a promising candidate for future studies or even trials regarding ovarian and cervical cancers. This review concluded that C. sativus can improve the symptoms of several female reproductive system disorders, which is particularly due to the presence of phytochemical ingredients, such as crocin, crocetin, and safranal.

Abstract
The antioxidant properties of crocin are attracting interest, yet the underlying mechanisms by which crocin mitigates oxidative stress-induced intestinal damage have not been determined. This study aimed to elucidate the effects of crocin on oxidative stress, apoptosis, and intestinal epithelial injury in intestinal epithelial cells (IPEC-J2). Using an H2 O2 -induced oxidative stress model in IPEC-J2 cells, crocin was added to assess its effects. Cell viability and apoptosis were evaluated using methyl thiazolyl tetrazolium assays and flow cytometry. Additionally, oxidative stress markers, such as superoxide dismutase (SOD), catalase (CAT), reactive oxygen species (ROS), and malondialdehyde (MDA), were quantified. We investigated, in which cell oxidation and apoptosis were measured at the gene and protein levels and employed transcriptome analysis to probe the mechanism of action and validate relevant pathways. The results showed that crocin ameliorates H2 O2 -induced oxidative stress by reducing ROS and MDA levels and by countering the reductions in CAT, total antioxidant capacity, and SOD. Crocin also attenuates the upregulation of key targets in the Nrf2 pathway. Furthermore, it effectively mitigated IPEC-J2 cell apoptosis caused by oxidative stress, as evidenced by changes in cell cycle factor expression, apoptosis rate, mitochondrial membrane potential, and apoptosis pathway activity. In addition, crocin preserves the integrity of the intestinal barrier by protecting tight junction proteins against oxidative stress. Transcriptome sequencing analysis suggested that the mitochondrial pathway may be a crucial mechanism through which crocin exerts its protective effects. In summary, crocin decreases oxidative stress molecule formation, inhibits Nrf2 pathway activity, prevents apoptosis-induced damage, enhances oxidative stress resistance in IPEC-J2 cells, and maintains redox balance in the pig intestine.

Abstract
Saffron is a spice derived from the flower of Crocus sativus L., which has been used for centuries as a coloring and flavoring agent, as well as a source of medicinal compounds. Saffron contains various bioactive constituents, such as crocin, crocetin, safranal, picrocrocin, and kaempferol, that have shown potential benefits for human health. Among them, crocin is the most abundant and characteristic constituent of saffron, responsible for its bright red color and antioxidant properties. One of the most promising applications of saffron and its constituents is in the prevention and treatment of neurological disorders, such as depression, anxiety, Alzheimer's disease, Parkinson's disease, and other brain disorders. Saffron and its constituents have been reported to exert neuroprotective effects through various mechanisms, such as modulating neurotransmitters, enhancing neurogenesis, reducing neuroinflammation, regulating oxidative stress, activating the Nrf2 signaling pathway, and modulating epigenetic factors. Several clinical and preclinical studies have demonstrated the efficacy and safety of saffron and its constituents in improving cognitive function, mood, and other neurological outcomes. In this review, we summarize the current evidence on the therapeutic potential of saffron and its constituents in neurological disorders, from bench to bedside. We also discuss the challenges and future directions for the development of saffron-based therapies for brain health.

Abstract
Crocin is the major active carotenoid of saffron (Crocus sativus L.). Its pluripotent effects have led to a growing body of literature investigating its antitumor properties as well as its diverse potentials for mood stabilization, normal tissue protection, and inflammation reduction; However, there is a gap in clinical trials testing this substance in cancer patients. In this randomized, double-blind, placebo-controlled clinical trial, patients with newly diagnosed esophageal squamous cell carcinoma were randomly assigned to either 30 mg/day of crocin or placebo, prescribed during the neoadjuvant chemo-radiotherapy. The primary endpoints were pathological response and toxicity, and secondary endpoints were depression and anxiety levels and survival analysis.

Abstract
Corneal diseases are a major cause of vision loss, often associated with aging, trauma and disease. Damage to corneal sensory innervation leads to discomfort and pain. Environmental stressors, such as short-wavelength light, can induce oxidative stress that alters mitochondrial function and affects cell and tissue homeostasis, including corneal innervation. Cellular antioxidant mechanisms may attenuate oxidative stress. This study investigates crocin, a derivative of saffron, as a potential antioxidant therapy. In vitro rat trigeminal sensory ganglion neurons were exposed to both sodium azide and blue light overexposure as a model of oxidative damage. Crocin was used as a neuroprotective agent. Mitochondrial and cytoskeletal markers were studied by immunofluorescence analysis to determine oxidative damage and neuroprotection. In vivo corneal innervation degeneration was evaluated in cornea whole mount preparations using Sholl analyses. Blue light exposure induces oxidative stress that affects trigeminal neuron mitochondria and alters sensory axon dynamics in vitro, and it also affects corneal sensory innervation in an in vivo model. Our results show that crocin was effective in preserving mitochondrial function and protecting corneal sensory neurons from oxidative stress. Crocin appears to be a promising candidate for the neuroprotection of corneal innervation.

Abstract
Cyclophosphamide is a drug used in chemotherapy. However, it has side effects, including changes in reproductive system functioning. Some herbal compounds can reduce the harmful effects of cyclophosphamide. This study aims to investigate the protective role of crocin against changes caused by Cyclophosphamide in ovarian tissue through changes in the expression of genes involved in the hypothalamic-pituitary-gonadal axis. This experimental study was performed on 24 adult female Wistar rats. Mice were divided into four groups (normal saline, 30 mg/kg cyclophosphamide, 100 mg/kg crocin and 30 mg/kg cyclophosphamide, and 200 mg/kg crocin and 30 mg/kg cyclophosphamide). At the end of the treatment period, the hypothalamus and ovaries were also removed to evaluate ob-Rb, ob-Ra, and NPY genes expression using real-time PCR and histological changes in the ovaries. Data were analyzed by SPSS statistical software. The expression of genes, number of follicles, and follicle diameter significantly decreased in the cyclophosphamide-treated groups compared with the control group. In the crocin and cyclophosphamide-treated groups, drug-induced reproductive complications were mitigated. The current findings indicate that by increasing the expression of genes ob-Rb, ob-Ra, and NPY, crocin could modulate the harmful effects of cyclophosphamide.

Abstract
Buffalo bull sperm suffer more cryoinjuries due to lipid peroxidation of high structural polyunsaturated fatty acid contents than cattle sperm. Consequently, the post-thaw fertilization potential of buffalo bull sperm is compromised. Crocin is a carotenoid known for its antioxidant potential through scavenging reactive oxygen species. Objectives of the current study were to investigate the effect of crocin addition in the semen extender on post-thaw quality, fertility-associated gene expression and fertilization potential of buffalo bull sperm. Semen samples (n = 32) from four Nili-Ravi buffalo bulls were extended with tris-citric acid extender containing different concentrations of crocin (0 mM; control, 0.5, 1, 1.5 and 2 mM). The extended semen was packed in 0.5 mL French straws (25 × 106 sperm/straw) and cryopreserved in liquid nitrogen. Computer-assisted semen analysis, hypo-osmotic swelling test, normal apical ridge assay, Rhodamine 123, acridine orange, propidium iodide staining, and thiobarbituric acid reactive substances assay were performed to assess sperm motility parameters, plasma membrane integrity, acrosome integrity, mitochondrial membrane potential, DNA integrity, viability, and lipid peroxidation, respectively. Expression levels of sperm acrosome-associated SPACA3, DNA condensation-related PRM1, anti-apoptotic BCL2, pro-apoptotic BAX, and oxidative stress-associated ROMO1 genes were evaluated through qPCR. The fertility of semen doses containing the most potent concentration of crocin (based on optimum post-thaw semen quality) was compared with control during the breeding season. Buffaloes (n = 400; 200/group) were inseminated 24 h after the onset of oestrus and transrectally palpated for pregnancy at least 60 days post-insemination. Results revealed that 0.5 and 1 mM crocin improved sperm post-thaw total motility, plasma membrane integrity, acrosome integrity, mitochondrial membrane potential and viability, and 1 and 1.5 mM crocin enhanced catalase activity and reduced lipid peroxidation compared to control (p < .05). Moreover, 1 mM crocin improved sperm post-thaw progressive motility, kinematics, and DNA integrity, and 1.5 mM crocin enhanced plasma membrane integrity than control (p < .05). Expression levels of SPACA3, PRM1 and BCL2 genes were higher (p < .05) with 1 mM crocin compared to other groups. In contrast, no difference (p > .05) was noticed in expressions of BAX and ROMO1 genes among all groups. The fertility rate of semen doses containing the most potent concentration (1 mM) of crocin was higher (p = .0465) compared to control (56 ± 0.03% vs. 46 ± 0.04%, respectively). In conclusion, 1 mM crocin in the semen extender improves post-thaw quality, fertility-associated gene expression and fertilization potential of buffalo bull sperm.

Abstract
Crocin is one of the most valuable components of the Chinese medicinal plant Crocus sativus and is widely used in the food, cosmetics, and pharmaceutical industries. Traditional planting of C. sativus is unable to fulfill the increasing demand for crocin in the global market, however, such that researchers have turned their attention to the heterologous production of crocin in a variety of hosts. At present, there are reports of successful heterologous production of crocin in Escherichia coli, Saccharomyces cerevisiae, microalgae, and plants that do not naturally produce crocin. Of these, the microalga Dunaliella salina, which produces high levels of β-carotene, the substrate for crocin biosynthesis, is worthy of attention. This article describes the biosynthesis of crocin, compares the features of each heterologous host, and clarifies the requirements for efficient production of crocin in microalgae.

Abstract
Crocin, a pharmacologically active component of Crocus sativus L. (saffron), has been informed to be beneficial in the treatment of stress-related oxidative impairment. In the present study, we examined the protective role of crocin against testicular damage induced by radiation (acute and fractionated) and the alteration of the AKT/FOXO signaling pathway. Male Wister albino rats were exposed to acute dose of 6 Gy and a fractionated dose of gamma radiation (2 Gy every 2 days up to 6 Gy total doses). Rats were pretreated intraperitoneally with crocin in a dose of 50 mg/kg for seven consecutive days prior to exposure to irradiation at a level of 6 Gy and during the fractionated irradiation of rats. Control groups were run concurrently. Ionizing radiation caused changes in the level of oxidative stress biomarkers manifested as elevation of thiobarbituric acid reactive substance, total nitrate/nitrite and reactive oxygen species (ROS) associated with a decrease in catalase as well as in the level of inflammatory parameters (decrease in expression of Nrf2 which was related to a significant increase in expression of NF-κB p65). Irradiation produced cellular damage characterized by an increase in serum lactate dehydrogenase. These findings were aligned with increased expression of the forkhead box O-1 (FOXO-1) and activation of protein kinase B (AKT) pathway. Irradiation of rats led to reduction in serum testosterone level and testicular weights. Pretreatment with the indicated dose of crocin shielded against the changes in all the evaluated parameters. Administration of crocin can be introduced as a novel preclinical approach for regulation of testicular damage induced by radiation; via controlling the ongoing oxidative stress and inflammatory reaction as well as activation FOXO/AKT signaling pathway.

Abstract
BACKGROUND Chronic rhinosinusitis with nasal polyps (CRSwNP) is subdivided into type 1 and type 2 inflammatory responses according to the mucosal inflammatory patterns. Crocin can reduce the level of T-helper type 2 cell (Th2) cytokines, such as interleukin-4 (IL-4), and inhibit the nuclear factor kappa-B (NF-κB) signaling pathway. OBJECTIVE This study aimed to investigate the role of group 2 innate lymphoid cells (ILC2s) in type 2 inflammation in eosinophilic nasal polyps and the inhibitory effect of crocin on this inflammation. METHODS Immunohistochemistry and immunofluorescence were used to detect the expression of transcription factors and the infiltration of ILC2s in tissues. An ILC2 stimulation model in vitro was constructed based on IL-33 stimulation and treated with crocin. The explant models were constructed and treated with crocin to detect the expression of type 2 inflammation-related factors. RESULTS Significantly more GATA-binding protein-3 (GATA3)-positive cells and chemoattractant receptor-homologous molecule expressed on T-helper type 2 cell (CRTH2)-positive cells, but fewer T-box expressed in T cell (T-bet)-positive cells, were found in eosinophilic nasal polyps (NPwEos). The expression levels of GATA3 and CRTH2 were significantly higher in NPwEos. Recombinant IL-33 stimulation increased the expression of GATA3, CRTH2, and type 2 cytokines (IL-4, IL-5, and IL-13) in ILC2s. In an IL-33-stimulated in vitro ILC2 culture model, crocin inhibited the type 2 inflammatory response, especially at lower concentrations (10 µM). The explant organoids of NPwEos were constructed in vitro, and Staphylococcus aureus enterotoxin B (SEB) was used to construct the type 2 inflammation model. Crocin at 10 µM concentration inhibited type 2 inflammation induced by SEB-stimulated explants. CONCLUSION Crocin inhibited type 2 inflammation induced by ILC2 activation at low concentrations via inhibiting the activation of NF-κB.

Abstract
The night-flowering Jasmine, Nyctanthes arbor-tristis also known as Parijat, is a perennial woody shrub belonging to the family of Oleaceae. It is popular for its fragrant flowers that bloom in the night and is a potent source of secondary metabolites. However, knowledge about its genome and the expression of genes regulating flowering or secondary metabolite accumulation is lacking. In this study, we generated whole genome sequencing data to assemble the first de novo assembly of Parijat and use it for comparative genomics and demographic history reconstruction. The temporal dynamics of effective population size (Ne ) experienced a positive influence of colder climates suggesting the switch to night flowering may have provided an evolutionary advantage. We employed multi-tissue transcriptome sequencing of floral stages/parts to obtain insights into the transcriptional regulation of nocturnal flower development and the production of volatiles/metabolites. Tissue-specific transcripts for mature flowers revealed key players in circadian regulation and flower development, including the auxin pathway and cell wall modifying genes. Furthermore, we identified tissue-specific transcripts responsible for producing numerous secondary metabolites, mainly terpenoids and carotenoids. The diversity and specificity of Terpene Synthase (TPS) and CCDs (Carotenoid Cleavage Deoxygenases) mediate the bio-synthesis of specialised metabolites in Parijat. Our study establishes Parijat as a novel non-model species to understand the molecular mechanisms of nocturnal blooming and secondary metabolite production.

Abstract
Crocin, a glycoside carotenoid that exhibits several health benefits, is mainly obtained from saffron (Crocus sativus L.), whose quality and content of phytochemicals can be strongly affected by environmental conditions. Therefore, in this work, the crocin content and in vitro antioxidant activity of saffron extracts obtained from three different varieties (Greek, Sicilian, and Iranian saffron) were assessed. Crocin content in saffron extracts was quantified via ultra-performance liquid chromatography coupled with mass spectrometry. The antioxidant activity of saffron extracts was evaluated using the oxygen radical absorbance capacity (ORAC) assay and nitric oxide (NO) radical scavenging test. The Maillard reaction was used to assess anti-glycation activity. Although the Sicilian and Iranian saffron extracts contained higher amounts of crocin (128 ± 6 ng/mL and 126 ± 4 ng/mL, respectively) compared to the Greek extracts (111 ± 2 ng/mL), ORAC values (50.9 ± 0.5) and % NO inhibition (35.2 ± 0.2) were higher for the Greek variety, which displayed a total phenolic content about two-fold greater than that of the other two extracts. Sicilian and Greek saffron had similar anti-glycation activities, while Iranian saffron was less effective. These results suggest that the antioxidant activity of saffron extracts could be ascribed to their naturally occurring complex mixture of phytochemicals, deserving further investigation as supplements to prevent pathological conditions induced by radical species.

Abstract
OBJECTIVE We evaluated the effects of crocin supplementation during culture of intact and half-destroyed four-cell mouse embryos. Outcomes measured included rate of cleavage arrest, blastocyst formation, and blastocyst cell number. METHODS We used laser to create two zonal holes without blastomere destruction in Groups 1 (n=100) and 2 (n=100), and to destroy two of the four blastomeres in Groups 3 (n=150) and 4 (n=150). Embryos were cultured in groups of ten in drops of medium without (Groups 1 and 3) or with 20 μg/ml of crocin supplementation (Groups 2 and 4). RESULTS Embryos in Groups 1 and 2 had no difference in the rate of cleavage arrest (6.0% vs. 7.0%, respectively; p=0.774) or blastocyst formation (89.0% vs. 86.0%, respectively; p=0.521). Neither was there a difference in the number of cells in the blastocysts (99.6±23.5 vs. 95.6± 8.2, respectively, p=0.83). Half-destroyed embryos cultured in crocin-supplemented medium (Group 4) had a lower rate of cleavage arrest (14.7% vs. 30.0%, p=0.001), and a higher rate of blastocyst formation (51.3% vs. 37.3%, p=0.015), than those in non-supplemented medium (Group 3). In blastocysts derived from half-destroyed embryos, there was no difference in the number of cells in ICM (14.5±3.9 vs. 13.7±2.9, p=0.285), TE (45.2±12.3 vs. 46.0±13.3, p=0.764), or total cells (59.7±12.2 vs. 59.7±14.8, respectively, p=0.990) among the two groups. CONCLUSIONS Crocin supplementation during in vitro development of impaired embryos improved their development, but had no effect on intact embryos.

Abstract
Membranous nephropathy (MN) is a glomerular disease. Crocin is isolated from saffron and gardenia. Its antioxidant, anti-inflammatory, anti-hyperlipidemic, anti-atherosclerotic, anti-tumor, free-radical scavenging and neuroprotective activities have been well established. We investigated the biological functions of crocin and its related mechanisms in MN. We established an experimental passive Heymann nephritis (PHN) rat model induced by anti-Fx1A antiserum. The rats were divided into sham, sham + crocin, PHN, PHN + crocin, and PHN + enalapril groups. Blood samples and kidneys of rats were collected for estimation of biochemical parameters in serum and oxidative stress indicators in kidney tissues. Histopathological changes of renal tissues were evaluated by hematoxylin and eosin, periodic acid-Schiff (PAS) and Masson staining. The podocyte number was estimated by immunohistochemistry staining of Wilms tumor type 1 (WT1). The deposition of rat anti-rabbit IgG antibodies, complement C3 and C5b-9 was detected by immunofluorescence staining. Western blotting was performed to measure the levels of Sirtuin 1 (Sirt1), nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1) and apoptosis-related proteins. The total cholesterol, triglycerides, creatinine, blood urea nitrogen, urine volume and urine albumin of PMN rats were significantly reduced by crocin. Additionally, crocin attenuated the renal histopathological changes. Moreover, the oxidative stress damage and podocyte loss and immune injury were relieved by crocin in PHN rats. Mechanistically, crocin administration activated the Sirt1/Nrf2/HO-1 pathways. The results provide a scientific basis that crocin could alleviate MN by inhibiting immune injury and podocyte damage through activating the Sirt1/Nrf2/HO-1 pathways.

Abstract
Crocin has been reported to have therapeutic effects on multiple cancers including colon cancer, but its specific mechanism is still ambiguous and needs to be further explored. Human colorectal adenocarcinoma cells (HCT-116) and human normal colonic epithelial cells (CCD841) were first treated with increasing concentrations of crocin. Subsequently, with 150 and 200 μM of crocin, the cell vitality was examined by cell counting kit 8. Cell apoptosis and proliferation were tested by TUNEL staining and colony formation assay, respectively. The expression of Ki-67 was assessed by immunofluorescence. Enzyme-linked immunosorbent assay was used to evaluate the level of inflammation- and oxidative-related factors. The reactive oxygen species (ROS) production and mitochondrial membrane potential (MMP) were examined by flow cytometer. Janus kinase (JAK), signal transducer and activator of transcription 3 (STAT3), and extracellular regulated protein kinases (ERK) in HCT-116 cells were tested by Western blot. Different concentrations of crocin barely affected the CCD841 cell vitality, while crocin restrained the HCT-116 cells vitality, proliferation and the expression of Ki-67, while inducing apoptosis in a concentration-dependent manner. Moreover, the contents of inflammation- and oxidative-related factors in HCT-116 cells were largely blunted by crocin that enhanced ROS and restrained the MMP and suppressed p-JAK2/JAK2, p-STAT3/STAT3, and p-ERK/ERK expression in HCT-116 cells. Crocin induced apoptosis and restored mitochondrial function in HCT-116 cells via repressing the JAK pathway. If the threptic effect works in patients, it could herald a new, effective treatment for colon cancer, improving the patients' prognosis and quality of life.

Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies, with continuously increasing cases and fatalities. Diagnosis often occurs in the advanced stages, confining patients to systemic therapies such as sorafenib. Sorafenib (SB), a multi-kinase inhibitor, has not yet demonstrated sufficient efficacy against advanced HCC. There is a strong argument in favor of studying its use in combination with other medications to optimize the therapeutic results. According to our earlier work, crocin (CR), a key bioactive component of saffron, hinders HCC development and liver cancer stemness. In this study, we investigated the therapeutic use of CR or its combination with SB in a cirrhotic rat model of HCC and evaluated how effectively SB and CR inhibited tumor growth in this model. Diethylnitrosamine (DEN) was administered intraperitoneally to rats once a week for 15 weeks, leading to cirrhosis, and then 19 weeks later, leading to multifocal HCC. After 16 weeks of cancer induction, CR (200 mg/kg daily) and SB (10 mg/kg daily) were given orally to rats for three weeks, either separately or in combination. Consistently, the combination treatment considerably decreased the incidence of dyschromatic nodules, nodule multiplicity, and dysplastic nodules when compared to the HCC group of single therapies. Combined therapy also caused the highest degree of apoptosis, along with decreased proliferating and β-catenin levels in the tumor tissues. Additionally, when rats received combined therapy with CR, it showed anti-inflammatory characteristics where nuclear factor kappa B (NF-κB) and cyclooxygenase-2 (Cox-2) were considerably and additively lowered. As a result, CR potentiates the suppressive effects of SB on tumor growth and provides the opportunity to strengthen the therapeutic effects of SB in the treatment of HCC.

Abstract
Application of herbal medicines in the treatment of diseases is in the center of attention of medical scientific societies. Saffron (Cricus sativus L.) is a medicinal plant belonging to the Iridaceae family with different therapeutic properties. The outcomes of human and animal experiments indicate that therapeutic impacts of saffron and its constituents, crocin, crocetin, and safranal, mainly are mediated via inhibiting the inflammatory reactions and scavenging free radicals. It has been suggested that saffron and crocin extracted from it also up-regulate the expression of sirtuin 1 (SIRT1) and nuclear factor erythroid 2-related factor 2 (Nrf2), down-regulate nuclear factor kappa B (NF-κB) signaling pathway and untimely improve the body organs dysfunction. Inhibition of inducible nitric oxide synthase and cyclooxygenase-2 (COX2) also is attributed to crocin. The current review narrates the therapeutic effects of saffron and its constituents on various body systems through looking for the scientific databases including Web of Science, PubMed, Scopus, and Google Scholar from the beginning of 2010 until the end of 2022.

Abstract
Studying the cis-trans isomerization process in crocin (CR), one of the few water-soluble carotenoids extracted from saffron, is important to better understand the physiological role of cis-carotenoids in vivo and their potential as antioxidants in therapeutic applications. For that, cis-trans isomerization of both methanol- and water-dissolved CR was induced by light or thermally generated singlet oxygen (1O2). The kinetics of molecular concentrations were monitored by both high-performance liquid chromatography (HPLC) and non-destructive spectrophotometric methods. These last made it possible to simultaneously follow the cis-trans isomerization, the possible bleaching of compounds and the amount of thermally generated 1O2. Our results were in accordance with a comprehensive model where the cis-trans isomerization occurs as relaxation from the triplet state of all-trans- or 13-cis-CR, whatever is the way to populate the CR triplet state, either by photon or 1O2 energy transfer. The process is much more (1.9 to 10-fold) efficient from cis to trans than vice versa. In H2O, a 1O2-induced bleaching effect on the starting CR was not negligible. However, the CR "flip-flop" isomerization reaction could still occur, suggesting that this process can represent an efficient mechanism for quenching of reactive oxygen species (ROS) in vivo, with a limited need of carotenoid regeneration.

Abstract
Gardenia jasminoides fruits are extensively grown worldwide, with a large harvest, and its major medicinal ingredients are geniposide and crocins. Research on their accumulation and biosynthsis-related enzymes is rare. In this study, the accumulation of geniposide and crocin of G. jasminoides fruits at different developmental stages were clarified by HPLC. The highest cumulative amount of geniposide was 2.035% during the unripe-fruit period, and the highest content of crocin was 1.098% during the mature-fruit period. Furthermore, transcriptome sequencing was performed. A total of 50 unigenes encoding 4 key enzymes related in geniposide biosynthsis pathways were screened, and 41 unigenes encoding 7 key enzymes in the pathways of crocin were elucidated. It was found that the expression levels of differentially expressed genes of DN67890_c0_g1_i2-encoding GGPS, which is highly related to geniposide biosynthesis, and DN81253_c0_g1_i1-encoding lcyB, DN79477_c0_g1_i2-encoding lcyE, and DN84975_c1_g7_i11-encoding CCD, which are highly related to crocin biosynthesis, were consistent with the accumulation of geniposide and crocin content, respectively. The qRT-PCR results showed that the trends of relative expression were consistent with transcribed genes. This study provides insights for understanding the geniposide and crocin accumulation and biosynthsis during fruit development in G. jasminoides.

Abstract
The successive steps of the oxidation mechanism of crocin, a major compound of saffron, by the free OH• radical are investigated by pulse radiolysis, steady-state (gamma) radiolysis methods, and molecular simulations. The optical absorption properties of the transient species and their reaction rate constants are determined. The absorption spectrum of the oxidized radical of crocin resulting from the H-abstraction presents a maximum of 678 nm and a band of 441 nm, almost as intense as that of crocin. The spectrum of the covalent dimer of this radical contains an intense band at 441 nm and a weaker band at 330 nm. The final oxidized crocin, issued from radical disproportionation, absorbs weaker with a maximum of 330 nm. The molecular simulation results suggest that the OH• radical is electrostatically attracted by the terminal sugar and is scavenged predominantly by the neighbor methyl site of the polyene chain as in a sugar-driven mechanism. Based on detailed experimental and theoretical investigations, the antioxidant properties of crocin are highlighted.

Abstract
Food supplements based on saffron (Crocus sativus L.) dried stigma extracts are widely consumed due to their multiple bioactive properties. Saffron extract (SE) standardization is of crucial importance, as it determines the reproducibility of the product quality and is essential for the evaluation of its bioactive effect and safety. Although SEs are commonly standardized considering their safranal content, the lack of specificity of the official methods may give inaccurate measurements. In addition to the development of more precise methodologies, the evaluation of alternative saffron components, such as crocins and picrocrocin, for standardization purposes would also be of interest. Thus, in this study, qualitative and quantitative information regarding picrocrocin and crocin isomers of different commercial saffron extracts was first obtained by a validated methodology using liquid chromatography (HPLC) coupled to diode array (DAD) and mass spectrometer (MS) detectors. Principal component analysis (PCA) was applied to gain insight into the compositional variability and natural grouping of SE. These studies suggested the potential use of the relative content of crocin isomers and trans-/cis-crocins and trans-4 GG/picrocrocin ratios as novel criteria for SE standardization. Their reproducibility and stability under controlled storage conditions for 36 months was demonstrated in a commercial standardized SE (affron®).

Abstract
Crocin has been reported to have antitumor activity in several tumors including breast cancer. Nevertheless, the mechanism of action of crocin on breast cancer remains unclear. The cytotoxicity of crocin was evaluated by CCK-8 assay. Cell proliferation was assessed using EdU incorporation assay and western blot analysis. Breast cancer-related genes were extracted from GEPIA. miR-122-5p targets were predicted using Targetscan, starbase, and miRDB softwares. Luciferase reporter assay was employed to confirm whether miR-122-5p targeted sprouty2 (SPRY2) and forkhead box P2 (FOXP2). Results showed that crocin exhibited cytotoxicity and suppressed the proliferation in breast cancer cells. miR-122-5p was upregulated in breast cancer tissues and cells. Crocin suppressed miR-122-5p to block the proliferation of breast cancer cells. Seven targets of miR-122-5p were identified in breast cancer. SPRY2 and FOXP2 were selected for further experiments due to their involvement in breast cancer. miR-122-5p targeted SPRY2 and FOXP2 to inhibit their expression. miR-122-5p knockdown restrained breast cancer cell proliferation by targeting SPRY2 and FOXP2. Additionally, crocin increased SPRY2 and FOXP2 expression by inhibiting miR-122-5p expression. Together, our results suggested that crocin inhibited proliferation of breast cancer cells through decreasing miR-122-5p expression and the subsequent increase of SPRY2 and FOXP2 expression.

Abstract
Digital stress is a newly identified cosmetic stress that is mainly characterized by blue light exposure. The effects of this stress have become increasingly important with the emergence of personal digital devices, and its deleterious effects on the body are now well-known. Blue light has been observed to cause perturbation of the natural melatonin cycle and skin damage similar to that from UVA exposure, thus leading to premature aging. "A melatonin-like ingredient" was discovered in the extract of Gardenia jasminoides, which acts as a filter against blue light and as a melatonin-like ingredient to prevent and stop premature aging. The extract showed significant protective effects on the mitochondrial network of primary fibroblasts, a significant decrease of -86% in oxidized proteins on skin explants, and preservation of the natural melatonin cycle in the co-cultures of sensory neurons and keratinocytes. Upon analysis using in silico methods, only the crocetin form, released through skin microbiota activation, was found to act as a melatonin-like molecule by interacting with the MT1-receptor, thus confirming its melatonin-like properties. Finally, clinical studies revealed a significant decrease in wrinkle number of -21% in comparison to the placebo. The extract showed strong protection against blue light damage and the prevention of premature aging through its melatonin-like properties.

Abstract
The preventive effect of saffron against Alzheimer's disease (AD) has been reported. Herein, we studied the effect of Cro and Crt, saffron carotenoids, on the cellular model of AD. The MTT assay, flow cytometry, and elevated p-JNK, p-Bcl-2, and c-PARP indicated the AβOs-induced apoptosis in differentiated PC12 cells. Then, the protective effects of Cro/Crt on dPC12 cells against AβOs were investigated in preventive and therapeutic modalities. Starvation was used as a positive control. RT-PCR and Western blot results revealed the reduced eIF2α phosphorylation and increased spliced-XBP1, Beclin1, LC3II, and p62, which indicate the AβOs-induced autophagic flux defect, autophagosome accumulation, and apoptosis. Cro and Crt inhibited the JNK-Bcl-2-Beclin1 pathway. They altered Beclin1 and LC3II and decreased p62 expressions, leading cells to survival. Cro and Crt altered the autophagic flux by different mechanisms. So, Cro increased the rate of autophagosome degradation more than Crt, while Crt increased the rate of autophagosome formation more than Cro. The application of 4μ8C and chloroquine as the inhibitors of XBP1 and autophagy, respectively, confirmed these results. So, augmentation of the survival branches of UPR and autophagy is involved and may serve as an effective strategy to prevent the progression of AβOs toxicity.

Abstract
Parkinson's disease is among the most common forms of neurodegenerative illness, with present treatment being primarily symptomatic and frequently coming with substantial adverse effects. Neuronal degeneration may arise due to a variety of pathological events, like inflammatory responses, neurotransmitter dysregulation, oxidative damage, mitochondrial malfunction, apoptosis, and genetic factors. The health issue and financial burden brought on by Parkinson's disease can worsen as the population ages. In the search for new and secure therapeutic agents for Parkinson's disease, several natural compounds have been shown to exert considerable neuroprotective benefits. Crocin, a naturally occurring carotenoid molecule, was found to have neuroprotective potential in the therapy of this disorder. Taking into account, the outcomes of various studies and the restorative actions of crocin, the present study emphasized the protective ability of crocin in this disease. Given the strong evidence supporting the neuroprotective ability of crocin, it is inferred that crocin inhibits inflammatory, apoptotic, and antioxidant processes through multiple mechanisms. Therefore, this compound is considered a safe and effective therapeutic choice for neurodegenerative illnesses like Parkinson's disease. However, more research on its efficacy as a treatment of Parkinson's disease is needed, specifically examining its mechanisms and the results obtained in clinical trials.

Abstract
BACKGROUND Diabetes is a multifactorial and growing disease, one of the severe complications of which is diabetic nephropathy (DN), which is the most common cause of chronic renal failure. FERM domain containing 3 (FRMD3) is responsible for maintaining the shape and integrity of nephron cells, and bone morphogenetic protein 7 (BMP7) helps maintain function and reduce kidney damage. This study aimed to evaluate the effect of crocin and losartan on biochemical parameters and the expression of FRMD3 and BMP7 genes in streptozotocin (STZ)-induced diabetic rats. METHODS Forty male Wistar rats were randomly divided into five experimental groups as healthy, diabetic control (D), crocin, losartan, and diabetic rats treated with losartan-crocin (n = 8). A single dose of STZ (50 mg/kg intraperitoneally injection) was used to induce diabetes. Four weeks after induction of diabetes, rats received crocin (50 mg/kg) and losartan (25 mg/kg) daily for four weeks orally. Rats were sacrificed at the end of the intervention, and blood samples were taken to determine serum levels of glucose, urea, creatinine (Cr), malondialdehyde (MDA), and thiol. Real-time polymerase chain reaction (PCR) was used to assess the expression of the FRMD3 and BMP7 genes in the kidney samples. RESULTS Diabetes induction increased serum levels of glucose, Cr, urea, MDA, and thiol, but decreased BMP7 and FRMD3 genes expression. Treatment with crocin and losartan decreased these biochemical parameters and increased the expression of the BMP7 and FRMD3 genes. DISCUSSION Crocin may be a promising therapeutic agent for preventing and improving diabetes-related kidney disease due to its antidiabetic and antioxidant properties.

Abstract
OBJECTIVES Crocin is a major class of medicinal components in saffron. This study aimed to determine whether crocin directly promotes the proliferation and osteogenic differentiation of human periodontal ligament stem cells (PDLSCs) in vitro and in vivo. MATERIALS AND METHODS CCK8 cell proliferation assay, reverse transcription quantitative polymerase chain reaction (RT-qPCR), Western blot analysis and Alizarin Red staining were performed in PDLSCs using crocin as a stimulant. DKK1 was used to selectively inhibit Wnt/β-catenin signaling, and Western blotting was performed to investigate the underlying mechanism. The PDLSCs were mixed with calcium phosphate cement and implanted into nude mice subcutaneously to study the effect of crocin on PDLSC osteogenic differentiation in vivo. RESULTS The CCK-8 assay showed that crocin did not promote the proliferation of PDLSCs. Treatment with 400 μM crocin significantly promoted PDLSC mRNA levels of ALP, COL1 and OCN; RUNX2 and BMP2 protein expression; mineralized nodule formation in vitro and in vivo; and ALP activity in tissues in vivo. In addition, crocin significantly promoted the phosphorylation of β-catenin and cyclin D1. DKK1 inhibits Wnt/β-catenin activation and partially reverses crocin-mediated promotion of PDLSC osteogenic differentiation. CONCLUSION Crocin may contribute to the regeneration of periodontal bone tissue.

Abstract
INTRODUCTION Crocin is one of the main components of Crocus sativus L. and can alleviate oxidative stress and inflammation in diabetic nephropathy (DN). However, the specific mechanism by which crocin treats DN still needs to be further elucidated. METHOD In the present study, a mouse model of DN was first established to investigate the therapeutic effect of crocin on DN mice. Subsequently, non-targeted metabolomics techniques were used to analyze the mechanisms of action of crocin in the treatment of DN. The effects of crocin on CYP4A11/PPARγ and TGF-β/Smad pathway were also investigated. RESULT Results showed that crocin exhibited significant therapeutic and anti-inflammatory, and anti-oxidative effects on DN mice. In addition, the non-targeted metabolomics results indicated that crocin treatment affected several metabolites in kidney. These metabolites were mainly associated with biotin metabolism, riboflavin metabolism, and arachidonic acid metabolism. Furthermore, crocin treatment upregulated the decreased levels of CYP4A11 and phosphorylated PPARγ, and reduced the increased levels of TGF-β1 and phosphorylated Smad2/3 in the kidneys of DN mice. CONCLUSION In conclusion, our study validated the considerable therapeutic, anti-inflammatory, and antioxidative impacts of crocin on DN mice. The mechanism of crocin treatment may be related to the regulation of biotin riboflavin and arachidonic acid metabolism, the activation of CYP4A11/PPARγ pathway, and the inhibition of TGF-β/Smad pathway in the kidney.

Abstract
BACKGROUND Among the many known adverse effects of methotrexate (MTX), hepatotoxicity stands out as a major drawback that limits its therapeutic applicability. There is growing evidence that crocin has antioxidant, anti-hyperglycemic, cardioprotective, and anti-inflammatory effects. This study's aim is to evaluate the potential protective effect of crocin against MTX-induced liver damage in rats using biochemical, histological, and immunohistochemical analyses. METHODS Twenty-four adult male albino rats were split into four groups at random (six rats/group) as follows: normal control (saline, intraperitoneal (i.p.) injections), crocin-treated (100 mg/kg daily for 14 days, i.p.), MTX-treated (20 mg/kg single i.p. injection on day 15), and crocin/MTX-treated groups (crocin 100 mg/kg/day for 14 days, i.p. + MTX 20 mg/kg single i.p. injection on day 15). On day 16 of the experiment, blood and tissue specimens were used to assess the liver functions, oxidative stress markers, transforming growth factor beta 1 (TGF-β1), caspase-3, BCL-2-associated X protein (BAX), and B-cell lymphoma 2 (BCL-2) expression. RESULTS The results of the current research revealed the protective actions of crocin against MTX-induced hepatotoxicity. Our results showed that crocin possesses antioxidants (decrease malondialdehyde (MDA), increase glutathione (GSH) levels, and enhance catalase (CAT) and superoxide dismutase (SOD) enzymatic activity), anti-fibrotic (decrease TGF-β1), and anti-apoptotic (decrease BAX and caspase-3 expression while increase BCL-2) actions in liver. Moreover, crocin administration along with MTX restores the normal histological structure of hepatic tissues. CONCLUSION The data presented in the current study using an in vivo animal model support the notion that crocin should be further studied in humans to assess its potential hepatoprotective effects against MTX-induced liver damage.

Abstract
Background Glial tumors are the most common primary malignant central nervous system tumors. They are hard to treat, not only because of the deregulation in multiple pathways but also because they are not contained in a well-defined mass with clear borders. The use of a single therapeutic agent to target gliomas has yielded unsatisfactory results. Objective A combination of molecules targeting multiple pathways may prove to be a better alternative. Methods The effect of caffeic acid phenethyl ester and crocin on the proliferation and death of U87-MG cells over a concentration range was analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase assays. A colony formation assay was used to measure the effect of caffeic acid phenethyl ester and crocin on contact inhibition and anchorage independence ability of U87-MG cells. Furthermore, apoptosis in U87-MG cells was analyzed by propidium iodide assay. Real-time polymerase chain reaction and Western blotting were performed to determine the expression level of p53, epidermal growth factor receptor, and proliferating cell nuclear antigen. Results Caffeic acid phenethyl ester and crocin when used in combination present an anticancer potential for glioma. These molecules, in combination, inhibit proliferation and induce apoptosis in U87-MG glioma cells. Our results provide evidence that combination treatment realigns the expression paradigm of p53, epidermal growth factor receptor, and proliferating cell nuclear antigen in cotreated U87-MG cells. Conclusions The combination of caffeic acid phenethyl ester and crocin led to inhibition in glioma cell proliferation and might prove to be an effective adjunct to the therapies in vogue.

Abstract
Myocardial infarction (MI) refers to myocardial ischemic necrosis that is caused by coronary artery disease. Notably, crocin has protective effects on the heart. The present study aimed to i) investigate the protective effect of crocin, an active ingredient in Gardenia jasminoides Ellis and Crocus sativus L., on myocardial ischemia and ii) to verify the interaction between crocin and kelch repeat and BTB domain‑containing protein 7 (KBTBD7), which is a novel member of the BTB‑kelch protein family. In the present study, the left anterior descending coronary artery was ligated to establish a myocardial ischemia‑reperfusion injury (MIRI) model in rats and the protective effect of crocin on rat myocardial tissue was observed. The levels of the inflammatory cytokines, interleukin (IL)‑1β, IL‑6 and tumor necrosis factor α (TNFα), in the sham, MI model, MI + crocin (100 mg/kg) and MI + crocin (200 mg/kg) groups were compared in the rat myocardial tissue. The TUNEL assay was used to detect apoptosis of myocardial cells. In addition, RAW264.7 cells were stimulated with the inflammatory factors recombinant mouse high mobility group box 1 (rmHMGB1) and recombinant mouse heat shock protein 60 (rmHSP60). The inhibitory effect of crocin on inflammatory cytokine levels was observed using ELISA. Western blotting was used to detect the inhibitory effect of crocin on KBTBD7. The inhibitory effect of KBTBD7 knockdown on MAPK and nuclear factor (NF)‑κB signaling pathways was also analyzed. The expression levels of IL‑1β, IL‑6 and TNFα were significantly decreased in the crocin‑treated groups compared with in the model group. Crocin significantly reduced the apoptosis of myocardial cells and significantly inhibited the release of inflammatory cytokines induced by rmHMGB1 and rmHSP60. KBTBD7 was determined to be a target of crocin. Knockdown of KBTBD7 significantly inhibited p38 and NF‑κB signaling pathways. Furthermore, the results demonstrated that KBTBD7 knockdown significantly reduced the production of inflammatory cytokines induced by rmHMGB1 and rmHSP60. KBTBD7 knockdown also significantly reduced p38 and NF‑κB signaling in the rmHMGB1‑ and rmHSP60‑treated groups. The present study demonstrated the potential protective effect of crocin on MIRI in rats. The underlying mechanism may be through direct inhibition of KBTBD7, thereby inhibiting excessive inflammatory responses and myocardial cell apoptosis following myocardial infarction.

Abstract
BACKGROUND Zearalenone (ZEA) is a mycotoxin produced by fungi and induces cytotoxicity by the generation of reactive oxygen species. The aim of this study was to evaluate and compare the nephroprotective effects of crocin and nano-crocin against ZEA-induced toxicity in HEK293 cell line via modulation of oxidative stress and special formulation to make nano-crocin. METHOD Nano-crocin physicochemical properties, such as size, load, appearance, and drug release profile were determined. Also, the viability of intoxicated HEK293 cells was evaluated by MTT assay. Furthermore, lactate dehydrogenase lipid Peroxidation (LPO), and oxidative stress biomarkers were measured. RESULT The best nano-crocin formulation with superior entrapment effectiveness (54.66 ± 6.02), more significant drug loading (1.89 ± 0.01), better zeta potential (-23.4 ± 2.844), and smaller particle size (140.3 ± 18.0 nm) was chosen. This study showed that treatment with crocin and nano-crocin in ZEA-induced cells, significantly decreased LDH and LPO levels and increased superoxide dismutase (SOD), catalase (CAT) activities, and total antioxidant capacity (TAC) levels compared to the control group. Moreover, nano-crocin had a more curative effect against oxidative stress than crocin. CONCLUSION Niosomal structure of crocin, when administered with the special formulation, may be more beneficial in reducing ZEA-induced in vitro toxicity than conventional crocin.

Abstract
Saffron (Crocus sativus L.) is a spice used worldwide as a colouring and flavouring agent. Saffron is also a source of multiple bioactive constituents with potential health benefits. Notably, saffron displays consistent beneficial effects against a range of human neurological disorders (depression, anxiety, sleeping alterations). However, the specific compounds and biological mechanisms by which this protection may be achieved have not yet been elucidated. In this review, we have gathered the most updated evidence of the neurological benefits of saffron, as well as the current knowledge on the main saffron constituents, their bioavailability and the potential biological routes and postulated mechanisms by which the beneficial protective effect may occur. Our aim was to provide an overview of the neuroprotective effects attributed to this product and its main bioactive compounds and to highlight the main research gaps that need to be further pursued to achieve full evidence and understanding of the benefits of saffron. Overall, improved clinical trials and adequately designed pre-clinical studies are needed to support the evidence of saffron and of its main bioactive components (e.g., crocin, crocetin) as a therapeutic product to combat neurological disorders.

Abstract
Crocin is a bioactive compound that naturally occurs in some medicinal plants, especially saffron and gardenia fruit. Different conventional and novel methods are used for its extraction. Due to some control conditions, recent methods such as ultrasonic extraction, supercritical fluid extraction, enzyme-associated extraction, microwave extraction, and pulsed electric field extraction are widely used because these methods give more yield and efficiency. Crocin is incorporated into different food products to make functional foods. However, it can also aid in the stability of food products. Due to its ability to protect against brain diseases, the demand for crocin has been rising in the pharmaceutical industry. It also contain antioxidant, anti-inflammatory, anticancer and antidepressant qualities. This review aims to describe crocin and its role in developing functional food, extraction, and bioavailability in various brain-related diseases. The results of the literature strongly support the importance of crocin against various diseases and its use in making different functional foods.

Abstract
The growth hormone secretagogue receptor-1a (GHSR1a) is the endogenous receptor for ghrelin. Activation of GHSR1a participates in many physiological processes including energy homeostasis and eating behavior. Due to its transitory half-life, the efficacy of ghrelin treatment in patients is restricted; hence the development of new adjuvant therapy is an urgent need. This study aimed to establish a cell line stably expressing GHSR1a, which could be employed to screen potential ghrelin agonists from natural compounds. First, by means of lentiviral transduction, the genome of a human HEK293T cell was modified, and a cell platform stably overexpressing GHSR1a was successfully established. In this platform, GHSR1a was expressed as a fusion protein tagged with mCherry, which allowed the monitoring of the dynamic cellular distribution of GHSR1a by fluorescent microscopy. Subsequently, the authenticity of the GHSR1a mediated signaling was further characterized by using ghrelin and teaghrelin, two molecules known to stimulate GHSR1a. The results indicated that both ghrelin and teaghrelin readily activated GHSR1a mediated signaling pathways, presumably via increasing phosphorylation levels of ERK. The specific GHSR1a signaling was further validated by using SP-analog, an antagonist of GHSR1a as well as using a cell model with the knockdown expression of GHSR1a. Molecular modeling predicted that crocin might be a potential ghrelin agonist, and this prediction was further confirmed by the established platform.

Abstract
Present study investigated the effect of continued training (CT) and interval training (IT) with crocin (C) supplementation on mitochondrial biogenesis and redox-sensitive transcription factors in liver tissue of type 2 diabetes (T2D) rats. Forty-eight high fat diet and streptozotocin- induced diabetic rats (mean age: 20 weeks, mean weight: 360.12 ± 12.11 g) were randomly divided into six groups including: (1) sham (Sh), (2) CT, (3) IT, (4) C (25 mg/kg/day), (5) CT + C, and (6) IT + C. IT and CT were performed 8 weeks for five sessions per week on treadmill with 80-85% and 50-55% of maximum speed running respectively. IT, CT and C decreased AP1 and increased LCAD (p ≤ .05); C increased SIRT1 (p ≤ .05); IT + C and CT + C decreased AP1 as well as increased NF-κB and LCAD (p ≤ .05); IT + C increased SIRT1, SIRST3 and PGC1-α (p ≤ .05). It appears that IT along with C compared to CT and C have favourable effect on mitochondrial biogenesis factors.

Abstract
Cardiovascular disease (CVD) is one of the most common causes of mortality around the world. The aim of this study is to summarize and conclude the clinical evidence regarding the use of Crocus sativus (C. sativus) and its ingredients on cardiovascular risk factors. A systematic search was conducted with PubMed, Web of Science (ISI), and Scopus in the English language from 2015 until September 2021. A fixed-effect or random-effects model were applied to pool standard mean difference (SMD) and its 95 % confidence intervals (CI). Randomized controlled studies that assessed the clinical effects of C. sativus and its ingredients on dietary intake (Energy, Carbohydrate, Protein, and total Fat) in human subjects were included. Seven studies comprising 421 participants were included in the meta-analysis. Pooling of results showed significant effect of saffron on total fat (−0.14; 95% CI: −0.49 to 0.20; I2 = 57.3%) and significant effect of crocin on Energy (0.94; 95% CI: −0.77 to 2.65; I2 = 95.9%), Carbohydrate (0.44; 95% CI: −0.74 to 1.62; I2 = 92.6%), and Protein (−0.04; 95% CI: −0.26 to 0.34; I2 = 0.0%). Present meta-analysis suggests that treatment with crocins is more effective than saffron in energy, carbohydrate, and protein, while saffron is more effective than crocins in fat. However, further studies are needed to confirm these findings.

Abstract
Diabetes mellitus is one of the most prevalent metabolic disorders that affect people of all genders, ages, and races. Medicinal herbs have gained attention from researchers and have been widely investigated for their antidiabetic potential. Saffron (Crocus sativus L.) and its main constituents, that is, crocin and crocetin, are natural carotenoid compounds, widely known to possess a wide spectrum of properties and induce pleiotropic anti-inflammatory, anti-oxidative, and neuro-protective effects. An increasing number of experimental, animal and human studies have investigated the effects and mechanism of action of these compounds and their potential therapeutic use in the treatment of diabetes. This narrative review presents the key findings of published clinical studies that examined the effects of saffron and/or its constituents in the context of diabetes mellitus. Moreover, an overview of the proposed underlying mechanisms mediating these effects, the medicinal applications of saffron, and the new findings regarding its effect on diabetes and various cellular and molecular mechanisms of action will be debated.

Abstract
The aim of this study was to compare crocins in the fruit of Gardenia jasminoides and Gardenia jasminoides var. radicans. Acchrom XCharge C_(18) column(4.6 mm×250 mm, 5 μm) was used for separation, with mobile phase of acetonitrile and 0.1% formic acid for gradient elution. The detection wavelength was set at 440 nm with a flow rate of 1.0 mL·min~(-1), and the column temperature was 30 ℃. The high performance liquid chromatography(HPLC) fingerprint of crocin in Gardenia species was established by testing 20 batches of G. jasminoides and 8 batches of G. jasminoides var. radicans samples from different sources, and UHPLC-ESI-Orbitrap-MS/MS technology and reference substances were used to predict and identify the common peaks. The results showed that 20 common chromatographic peaks from the samples were selected and the structures of 16 common peaks were predicted by mass spectrum. Four common peaks(crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ) were identified by the comparison with reference substances. The content of crocin Ⅰ, Ⅱ, Ⅲ, and Ⅳ was determined simultaneously under the same chromatographic condition, and both the system suitability and the methodological investigation results met the requirements of content determination. The relative similarity of HPLC fingerprint of 28 samples to the reference fingerprint was above 0.98. The results of cluster analysis(CA) showed that G. jasminoides and G. jasminoides var. radicans were separately grouped into one group. In the 20 batches of G. jasminoides, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 3.58-9.58, 0.230-1.452, 0.014 5-0.135, and 0.301-1.12 mg·g~(-1), respectively, and the total content was between 4.12-12.25 mg·g~(-1). In the 8 batches of G. jasminoides var. radicans, the content of crocin Ⅰ, Ⅱ, Ⅳ, and Ⅲ was between 5.84-11.48, 0.308-0.898, 0.010 6-0.025 5, and 0.675-1.34 mg·g~(-1), respectively, and the total content was between 6.97-13.72 mg·g~(-1). The existing results showed that there is a certain similarity between G. jasminoides and G. jasminoides var. radicans in the composition of crocin, which needs further proved by more batches of samples. The method established in this paper provides references for the quality control of G. jasminoides, G. jasminoides var. radicans, and related products.

Abstract
This study investigated the microbial decontamination of saffron using the low-pressure cold plasma (LPCP) technology. Therefore, other quality characteristics of saffron that create the color, taste, and aroma have also been studied. The highest microbial log reduction was observed at 110 W for 30 min. Total viable count (TVC), coliforms, molds, and yeasts log reduction were equal to 3.52, 4.62, 2.38, and 4.12 log CFU (colony-forming units)/g, respectively. The lowest decimal reduction times (D-values) were observed at 110 W, which were 9.01, 3.29, 4.17, and 8.93 min for TVC, coliforms, molds, and yeasts. LPCP treatment caused a significant increase in the product's color parameters (L*, a*, b*, ΔE, chroma, and hue angle). The results indicated that the LPCP darkened the treated stigma's color. Also, it reduced picrocrocin, safranal, and crocin in treated samples compared to the untreated control sample (p < .05). However, after examining these metabolites and comparing them with saffron-related ISO standards, all treated and control samples were good.

Abstract
The present systematic and meta-analysis study was designed to show the protective impact of saffron and crocin supplementation on hyperlipidaemia and hyperglycaemia in randomised and clinical trials (RCTs). A pooled analysis using a model for random-effects showed that HDL-C levels were 0.21 fold higher in the saffron and 0.01 fold higher in the crocin group than placebo. LDL-C levels in the saffron group reduced by 0.51 and 0.04 fold in the crocin group versus the placebo. Moreover, TC levels in the saffron group were 0.19 lower and 0.11 fold lower in crocin group than in the placebo group. TG level in saffron group was 0.04 lower and 0.02 fold lower in crocin than the control group. The blood glucose levels did not significantly differ from the control group. This study suggests that saffron and crocin may modulate the serum lipid profile in patient with metabolic disorders.

Abstract
Background: Chronic obstructive pulmonary disease (COPD) is a progressive and chronic respiratory disorder characterized by reversible airflow limitation and lung parenchyma destruction. The main feature of COPD is inflammation and disturbance of the oxidant/antioxidant balance in the airways. The therapeutic use of herbal supplements with antioxidant and anti-inflammatory properties seems to be very useful in the medical management of patients with COPD. Method: COPD patients were divided into placebo and intervention groups (each group n = 23) in a clinical trial study. The intervention group received crocin supplementation (30 mg/day for 12 weeks), and the control group received a placebo. Pre- and after the intervention, pulmonary function tests (PFTs), exercise capacity (using a 6-min walking distance test (6MWD)), and serum levels of total oxidant status (TOS), total antioxidant capacity (TAOC), and NF-kB were assessed using the ELISA test. Results: Intervention with crocin for 12 weeks in COPD patients decreased serum levels of TOS and NF-κB as well as increased TAOC. In addition, the results of the 6MWD test reveal an improvement in patients' exercise capacity. Conclusion: Crocin supplementation appears to effectively establish oxidant/antioxidant balance and improve inflammatory conditions in patients with COPD.

Abstract
Polycystic ovary syndrome (PCOS) is a multifactorial reproductive condition common in women of reproductive age. Hyperlipidemia, insulin resistance, obesity, and chronic low-grade inflammation are associated with PCOS. In a clinical trial study, women with PCOS were divided into two groups (n = 25 each): the intervention group receiving crocin (15 mg, twice daily) and the control group receiving a placebo. The duration of intervention in both groups was 12 weeks. Pre- and postintervention, demographic information, lipid profile, fasting blood glucose (FBG), fasting insulin, and inflammatory markers (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-α]) were measured. Intervention with crocin significantly increased the mean high-density lipoprotein cholesterol postintervention compared to the placebo group, while exerting a suppressive effect on the increase in mean low-density lipoprotein cholesterol, triglycerides, and cholesterol levels. Intervention with crocin also exerted inhibitory effects on changes in FBG and insulin, so that crocin improved insulin and cardioprotective indices. Finally, despite the increased inflammatory markers (IL-6 and TNF-α) in the placebo group, crocin treatment had protective effects on their increased changes. Thus, crocin supplementation could be considered in the therapeutic targets of women with PCOS.

Abstract
Abnormal dislocation of cone opsin protein affects the sensitivity function of photoreceptors and results in depressed central vision. Nutraceutical therapy is needed to restore the residual function of photoreceptors. Crocin is a natural substance for retinal health. However, its effect on the restoration of functional vision and its underlying mechanisms have not been fully studied. This study analyzed the restorative effect of crocin on residual functional vision in vivo in a mouse model. High-energy light-evoked photoreceptor dysfunction was confirmed by M opsin dislocation in the retina accompanied by a loss of functional vision. Crocin treatment significantly increased brain-derived neurotrophic factor (BDNF) protein in retinas, thus contributing to the re-localization of the M opsin protein, restoration of the visual acuity (VA), and high spatial frequency-characterized visual contrast sensitivity function (VCSF). In contrast, such effects were significantly reversed after the washout period. Additionally, the restorative effect of crocin on functional vision and M opsin re-localization can be reversed and blocked by synchronous injection of a tropomyosin receptor kinase B (TrkB) receptor antagonist (ANA-12). This study demonstrated the major functional vision-rescuing or restoring effect of crocin in vivo by modulating M opsin location plasticity and increasing the capacity of the residual photoreceptor function through the BDNF-TrkB receptor pathway.

Abstract
Temporal lobe epilepsy (TLE) is a common kind of refractory epilepsy. More than 30% TLE patients were multi-drug resistant. Some patients may even develop into status epilepticus (SE) because of failing to control seizures. Thus, one of the avid goals for anti-epileptic drug development is to discover novel potential compounds to treat TLE or even SE. Crocin, an effective component of Crocus sativus L., has been applied in several epileptogenic models to test its anti-epileptic effect. However, it is still controversial and its effect on TLE remains unclear. Therefore, we investigated the effects of crocin on epileptogenesis, generalized seizures (GS) in hippocampal rapid electrical kindling model as well as SE and spotaneous recurrent seizure (SRS) in pilocarpine-induced TLE model in ICR mice in this study. The results showed that seizure stages and cumulative afterdischarge duration were significantly depressed by crocin (20 and 50 mg/kg) during hippocampal rapid kindling acquisition. And crocin (100 mg/kg) significantly reduced the incidence of GS and average seizure stages in fully kindled animals. In pilocarpine-induced TLE model, the latency of SE was significantly prolonged and the mortality of SE was significantly decreased by crocin (100 mg/kg), which can also significantly suppress the number of SRS. The underlying mechanism of crocin may be involved in the protection of neurons, the decrease of tumor necrosis factor-α in the hippocampus and the increase of brain derived neurotrophic factor in the cortex. In conclusion, crocin may be a potential and promising anti-epileptic compound for treatment of TLE.

Abstract
Saffron is a valued herb, obtained from the stigmas of the C. sativus Linn (Iridaceae), with therapeutic effects. It has been described in pharmacopoeias to be variously acting, including as an anti-depressant, anti-carcinogen, and stimulant agent. The therapeutic effects of saffron are harbored in its bioactive molecules, notably crocins, the subject of this paper. Crocins have been demonstrated to act as a monoamine oxidase type A and B inhibitor. Furthermore, saffron petal extracts have experimentally been shown to impact contractile response in electrical field stimulation. Other research suggests that saffron also inhibits the reuptake of monoamines, exhibits N-methyl-d-aspartate antagonism, and improves brain-derived neurotrophic factor signaling. A host of experimental studies found saffron/crocin to be similarly effective as fluoxetine and imipramine in the treatment of depression disorders. Saffron and crocins propose a natural solution to combat depressive disorders. However, some hurdles, such as stability and delivery, need to be overcome.

Abstract
Crocin, as a nutraceutical component of saffron (Crocus sativus L.), possesses numerous therapeutic effects. In the current study, a crocin-loaded chitosan/alginate (CS/ALG) nanocarrier was developed for oral delivery. The influence of preparation variables including pH and the concentrations of CS, ALG, and calcium chloride (CaCl2 ) on encapsulation efficiency (EE%) and loading efficiency (LE%) of CS/ALG nanoparticles (NPs) was evaluated by L9 Taguchi orthogonal array (OA). The results showed that at 0.25% w/v CS, 0.1% w/v ALG, pH 4.5, and absence of CaCl2 , crocin was loaded into CS/ALG NPs with EE% and LE% of 91.5% and 27.4%, respectively. Ultrasonication reduced the particle sizes (PSs) up to 100 nm, and freeze-dried NPs reproduced the particles with average size of 90 nm. Scanning electron microscopy (SEM) was successfully used to characterize the structure and morphology of freeze-dried NPs, confirming very fine NPs having sizes less than 100 nm. Crocin loaded into NPs showed higher stability in simulated gastric pH 2 compared to free crocin (2.1% and 7.5% degradation at 60 min, respectively). Furthermore, a pH-dependent sustained crocin release was observed with faster release at pH 2. Overall, the very small PS along with high encapsulation efficiency and stability can enhance crocin oral bioavailability making CS/ALG nanovehicles promising as an effective delivery system. PRACTICAL APPLICATION: Crocin as a functional component of Saffron is not sufficiently stable in gastrointestinal tract and its absorption is not complete. Chitosan/Alginate nanoparticles can encapsulate it efficiently, protect it and enhance its absorption orally. The availability and simplicity of the materials and equipments employed in current research provide the possibility to industrial scale up of the Crocin nanoparticles.

Abstract
Crocin has been extensively investigated in treating neurodegenerative diseases. However, its effect on cognitive impairment associated with atherosclerosis remains unknown. The present study aimed to explore the potential mechanism of crocin on cognitive impairment in a mouse model of atherosclerosis. LDLR-/- mice fed a high-fat/cholesterol diet were administered variable-dose crocin for 56 days through gavage. Biochemical tests showed that serum triglycerides and circulating lipopolysaccharide decreased in mice treated with crocin. Behavioral tests indicated that crocin alleviated cognitive impairment by reducing latency to the platform and increasing the swimming distance in the target quadrant. This mechanism might be associated with crocin inhibiting Aβ deposition by decreasing Aβ1-42 and tau phosphorylation. Crocin improved neuroinflammation by inhibiting the increase in reactive microglia and astrocytes, weakening NLRP3 inflammasome activation accompanied by a reduction in Caspase-1 and IL-1β, and blocking TLR4 signaling accompanied by a decrease in NF-kB p65 and MyD88. In addition, crocin raised the protein expression of ZO-1 and occludin. These findings provide experimental support that crocin attenuates cognitive impairment associated with atherosclerosis by repressing neuroinflammation, which is attributed to its suppression on the activation of microglia and astrocytes, and the production of inflammatory cytokines via targeting the NLRP3 inflammasome and TLR4 signaling.
