Twist1 Regulates the Immune Checkpoint VISTA and Promotes the Proliferation, Migration and Progression of Pancreatic Cancer Cells

Pancreatic cancer is one of the deadliest malignant tumours worldwide. Despite the developments in the treatments of pancreatic cancer, survival rates remain at a low level, and the mechanisms underlying the aggressive course of the cancer are not fully understood. VISTA is an immune checkpoint and has recently become a significant target in cancer treatment; however, the roles of VISTA in the development of pancreatic cancer have largely remained unknown. Histone deacetylase inhibitors (HDACi) have been reported to reverse the epithelial-mesenchymal transition (EMT) and may enhance the efficacy of anti-PD-1 therapy. The PD-L1/PD-1 immune checkpoint targeted by this therapy shares structural similarity with VISTA. Moreover, combination therapy of vorinostat and anti-PD-1 has been shown to significantly reduce tumour growth by suppressing the transcription factor c-Myc. Therefore, in this study, we aim to investigate the genes that are associated with EMT and explore the potential mechanism involving Twist1, a proto-oncogene, and VISTA in pancreatic cancer. We also sought to determine the synergistic effects of an HDACi, vorinostat, in combination with Twist1-siRNA on VISTA expression in pancreatic cancer cells' viability and proliferation. Our results revealed that Twist1 blockade in combination with vorinostat in pancreatic cancer cells suppresses EMT-associated genes and the immune checkpoint VISTA compared to treatments administered alone. As a result, identifying the genes associated with EMT in pancreatic cancer and understanding the role of Twist1 in this process is a crucial step to contribute to the identification of new targets for pancreatic cancer treatment and the improvement of existing treatment strategies.

Facilitation of infectious and non-infectious wound healing using Morus nigra fruit extract ointment: An in vitro and in vivo study

Accelerating wound healing, as well as preventing infection and scar formation are among the most important medical challenges. This study aims to examine the antimicrobial, immunomodulatory, and anticancer properties of Morus nigra. The antimicrobial activities of ripe and unripe M. nigra fruit (MNF) extracts were tested. HPLC was employed to measure the components in the extract. Oserin ointment was made with 8 % extract. To test the ointment, 48 Wistar rats were randomly assigned into eight groups. The ointment was used daily by treating the wounds. Tissue histology and wound healing were assessed over nine days. Comparative evaluation of wound healing was conducted by analyzing TGF-β, TNF-α, and IL-1 mRNA levels. Finally, cytotoxic effects on AGS cancer and NIH-3 T3 fibroblast cells were examined. The ANOVA test and Prsim program were used for statistical analysis. Unripe MNF extract had good antimicrobial properties in standard and nosocomial strains. The most abundant compound in the extract was ascorbic acid (0.0441 mg/10 mg extract), followed by naringenin and gallic acid. In all groups treated with MNF extract ointment, a significant reduction in wound area was observed compared to other groups (p < 0.05). After six days of treatment, the microbial load was uncountable. In the microscopic studies of the wounds, a significant increase was observed in fibroblasts, angiogenesis, and in neutrophils in the first days as well as a decrease in the final days. The treatment caused a significant decline in the expression of IL-1 and TNF-α genes, as well as an increase in the expression of TGF-β (p < 0.05). This extract had no significant cytotoxic effects on human fibroblast cells (p > 0.05). In general, it can be concluded that the unripe MNF extract ointment can be a suitable option for the treatment of infectious and non-infectious skin wounds.

TRPV1-Dependent Antiproliferative Activity of Dioecious Maclura pomifera Extracts in Estrogen Receptor-Positive Breast Cancer Cell Lines Involves Multiple Apoptotic Pathways

Globally, breast cancer is a significant cause of mortality. Recent research focused on identifying compounds regulating the transient receptor potential vanilloid 1 (TRPV1) ion channel activity for the possibility of developing cancer therapeutics. In this study, the antiproliferative properties and mechanisms of action through TRPV1 of Maclura pomifera, a dioecious tree native to the south-central USA, have been investigated. Male and female extracts of spring branch tissues and leaves (500 µg/mL) significantly reduced the viability of MCF-7 and T47D cells by 75-80%. M. pomifera extracts induced apoptosis by triggering intracellular calcium overload via TRPV1. Blocking TRPV1 with the capsazepine antagonist and pretreating cells with the BAPTA-AM chelator boosted cell viability, revealing that M. pomifera phytochemicals activate TRPV1. Both male and female M. pomifera extracts initiated apoptosis through multiple pathways, the mitochondrial, ERK-induced, and endoplasmic reticulum-stress-mediated apoptotic pathways, demonstrated by the expression of activated caspase 3, caspase 9, caspase 8, FADD, FAS, ATF4, and CHOP, the overexpression of phosphorylated PERK and ERK proteins, and the reduction of BCL-2 levels. In addition, AKT and pAKT protein expressions were reduced in female M. pomifera-treated cells, revealing that female plant extract also inhibits PI3K/Akt signaling pathways. These results suggest that phytochemicals in M. pomifera extracts could be promising for developing breast cancer therapeutics.

The Effect of Phenolic-Rich Extracts of Rubus fruticosus, R. ulmifolius and Morus nigra on Oxidative Stress and Caco-2 Inhibition Growth

Currently, a clear interest has been given to berries due to their richness in active metabolites, including anthocyanins and non-coloured phenolics. Therefore, the main aim of the present work is to investigate the phenolic profile, antioxidant abilities, and antiproliferative effects on normal human dermal fibroblasts (NHDF) and human colon carcinoma cell line (Caco-2) cells of phenolic-rich extracts from three red fruits highly appreciated by consumers: two species of blackberries (Rubus fruticosus and Rubus ulmifolius) and one species of mulberry (Morus nigra). A total of 19 different phenolics were identified and quantified by HPLC-DAD-ESI/MSn and HPLC-DAD, respectively. Focusing on the biological potential of the phenolic-rich extracts, all of them revealed notable scavenging abilities. Concerning the antiproliferative properties, R. fruticosus presented a cytotoxic selectivity for Caco-2 cells compared to NHDF cells. To deeper explore the biological potential, combinations with positive controls (ascorbic acid and 5-fluorouracil) were also conducted. Finally, the obtained data are another piece of evidence that the combination of phenolic-rich extracts from natural plants with positive controls may reduce clinical therapy costs and the possible toxicity of chemical drugs.

A Novel Strategy for Mixed Jam Evaluation: Apparent Indicator, Sensory, Metabolomic, and GC-IMS Analysis

Jam is a popular traditional and modern food product for daily consumption. However, the benefits of mixed jams over single-fruit jams have not been thoroughly explored, with analyses limited to superficial indices. In this study, Xinjiang special Morus nigra L. and Prunus domestica L. were used as raw materials to prepare single-fruit and mixed jams, and their differences in antioxidants, organoleptic qualities, pH, texture, and color were analyzed. The dynamics of metabolites before and after thermal processing were assessed using untargeted metabolomics. The results indicate that the main metabolites were flavonoids, terpenoids, amino acids, phenolic acids, and carbohydrates. Flavonoid metabolites changed significantly after thermal processing, with 40 up-regulated and 13 down-regulated. During storage, polyphenols were the prominent differential metabolites, with fifty-four down-regulated and one up-regulated. Volatile aroma components were analyzed using gas chromatography-ion mobility spectrometry (GC-IMS); the aroma components E-2-hexenal, E-2-pentenal, 3-methylbutanal, 1-penten-3-ol, tetrahydro-linalool, 1-penten-3-one, hexyl propionate, isoamyl acetate, α-pinene, and propionic acid in mixed jam were significantly higher than in single-fruit jam. In this study, untargeted metabolomics and GC-IMS were used to provide a more comprehensive and in-depth evaluation system for jam analysis.

Central MOTS-c infusion affects reproductive hormones in obese and non-obese rats

MOTS-c, a mitochondrial-derived peptide, acts as a systemic hormone and MOTS-c level is inversely correlated with markers of obesity. Obesity is a risk factor for male reproductive physiology and is expressed as an important cause of infertility. In this study, we aimed to determine the effects of MOTS-c, which has been proven in the hypothalamus and testicles, on the actors involved in the reproductive axis. In the study, 80 male Wistar-Albino rats were divided into two main groups, obese and non-obese (n = 40). Rats in the first main group were fed with fatty diet feed and obesity was induced. The second main group was fed with normal diet feed. Each main group was divided into 4 subgroups (Control, Sham, 10 and 100 µM MOTS-c). The lateral ventricles of the animals in the treatment groups were infused with 10 and 100 µM MOTS-c (solvent in Sham group) for 14 days. At the end of the experiment, hypothalamic Gonadotropin-Releasing Hormone (GnRH) gene expression level, serum testosterone, Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels were determined. MOTS-c infusion caused an increase in GnRH mRNA, protein expression levels and serum testosterone, LH and FSH levels in obese and non-obese rats (p < 0.05). MOTS-c administration more significantly upregulated hormone levels in non-obese rats (p < 0.05). MOTS-c administration increases these hormones, suggesting that MOTS-c may stimulate the reproductive axis. Our results reveal that MOTS-c plays a role in the central regulation of reproduction, as well as causes increased LH, FSH and testosterone release.

The phenolic components extracted from mulberry fruits as bioactive compounds against cancer: A review

In Asia, mulberry has long been used to treat various infectious and internal ailments as a traditional medication. The compounds found in it have the potential to improve human health. Because there is no approved and defined evaluation procedure, it has not been formally or scientifically recognized. As a result of these investigations, a new frontier in traditional Chinese medicine has opened up, with the possibility of modernization, for the interaction between active components of mulberry and their biological activities. These studies have used current biotechnological technologies. For ages, mulberry has been used as an herbal remedy in Asia to cure various diseases and internal disorders. It has a high concentration of bioactive chemicals that benefit human health. The most abundant phenolic components extracted from white mulberry leaves are flavonoids (Kuwanons, Moracinflavans, Moragrols, and Morkotins), phenolic acids, alkaloids, and so forth. Flavonoids, benzofurans, chalcones, and alkaloids have been discovered to have cytotoxic effects on human cancer cell lines. There is growing evidence that mulberry fruits can potentially prevent cancer and other aging-related disorders due to their high concentration of bioactive polyphenolic-rich compounds and macro and micronutrients. Anthocyanins are rapidly absorbed after eating, arriving in the plasmalemma within 15-50 min and entirely removed after 6-8 hr. Due to a lack of an approved and consistent technique for its examination, it has yet to be formally or scientifically recognized. The mulberry plant is commercially grown for silkworm rearing, and less attention is paid to its bioactive molecules, which have a lot of applications in human health. This review paper discusses the phenolic compounds of white mulberry and black mulberry in detail concerning their role in cancer prevention.

Characterization, immunostimulatory and antitumor activities of a β-galactoglucofurannan from cultivated Sanghuangporus vaninii under forest

A biomacromolecule, named as β-galactoglucofurannan (SVPS2), was isolated from the cultivated parts of Sanghuangporus vaninii under the forest. Its primary and advanced structure was analyzed by a series of techniques including GC-MS, methylation, NMR, MALS as well as AFM. The results indicated that SVPS2 was a kind of 1, 5-linked β-Glucofurannan consisting of β-glucose, β-galactose and α-fucose with 23.4 KDa. It exhibited a single-stranded chain with an average height of 0.72 nm in saline solution. The immunostimulation test indicated SVPS2 could facilitate the initiation of the immune reaction and promote the secretion of cytokines in vitro. Moreover, SVPS2 could mediate the apoptosis of HT-29 cells by blocking them in S phase. Western blot assay revealed an upregulation of Bax, Cytochrome c and cleaved caspase-3 by SVPS2, accompanied by a downregulation of Bcl-2. These results collectively demonstrate that antitumor mechanism of SVPS2 may be associated with enhancing immune response and inducing apoptosis of tumor cells in vitro. Therefore, SVPS2 might be utilized as a promising therapeutic agent against colon cancer and functional food with immunomodulatory activity.

Phytochemical characterization of Morus nigra fruit ultrasound-assisted ethanolic extract for its cardioprotective potential

The current work investigated the phytochemical profile of ultrasound-assisted ethanolic extract of Morus nigra (M. nigra) fruit. FTIR analysis of M. nigra fruit extract revealed the presence of alcohols (O-H), alkanes (C-H stretch), alkenes (C=C), and alkynes (C≡C). The HPLC analysis quantified the quercetin, gallic acid, vanillic acid, chlorogenic acid, syringic acid, cinnamic acid, sinapic acid, and kaempferol. Furthermore, the cardioprotective activity of ethanolic extract of M. nigra fruit was investigated. Cholesterol supplementation (2%) in the daily diet and exposure to cigarette smoke (2 cigarettes twice a day) were to induce hypertension in rats. The experimental animals were categorized into four groups: G0 (negative control), G1 (positive control), G2 (standard drug), and G3 (M. nigra fruit). The fruit extract administration at 300 mg/kg BW/day orally for 2 months significantly (p < .001) enhanced the activities of serum and cardiac tissue antioxidants in hypertensive rats. Meanwhile, the fruit extract reduced the elevated serum lipid profile while significantly increasing the high-density lipoproteins in G3 than G1 and G2. The increase in blood pressure, liver transaminases, and serum lactate dehydrogenase also reduced significantly in M. nigra fruit extract-treated rats. Histopathological findings revealed mild normalization of cardiac myocytes with central nuclei, branching, and cross-striations. Consequently, the M. nigra fruit extract exerted the cardioprotective potential via increasing the antioxidant enzymes and reducing the lipids, lactate dehydrogenase, liver transaminases, and blood pressure. The therapeutic potential of M. nigra fruit can be due to flavonols and phenolic acids. PRACTICAL APPLICATIONS: The present work quantified the Morus nigra fruit phytochemicals and its significant role in reducing lipid markers and blood pressure and improving antioxidant status in rats fed a hypercholesterolemic diet and exposed to cigarette smoke. Conclusively, the inclusion of M. nigra fruit in daily diet could improve the cardiac health of the individuals. Furthermore, the therapeutic potential of M. nigra fruit and its isolated constituents in modulating the gene expression against cardiac problems can explore after clinical trials and standardization in higher animals.

Capsanthin induces death in human prostate cancer cell lines by inducing DNA damage

There is a relationship between a person’s diet and the development and prevention of some cancers. Carotenoids are found as various natural pigments in many fruits and vegetables. Studies on carotenoids and their potential roles in carcinogenesis are increasing in importance day by day. In this study, we aimed to determine the cytotoxic and genotoxic effects of capsanthin, a carotenoid compound, in human prostate cancer cell lines.

After different concentrations of capsanthin were applied to human prostate cancer cell lines (LNCaP and PC-3), the effects of the compound on cell viability were determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) test. The single-cell gel electrophoresis (Comet) assay was then used to reveal the genotoxic effects of probable cytotoxic dosages on cell DNA. After the treatments, apoptotic cell death levels were determined by Tunel staining. At high concentrations, capsanthin dramatically reduced PC-3 and LNCaP cell viability (p<0.05). In addition, capsanthin caused DNA damage and apoptotic cell death in the prostate cancer cells. The results show that capsanthin reduces cell viability by causing genotoxicity in prostate cancer cells.

Phytochemicals, Pharmacological Effects and Molecular Mechanisms of Mulberry

There are numerous varieties of mulberry, and each has high medicinal value and is regarded as a promising source of traditional medicines and functional foods. Nevertheless, the nutrients and uses of mulberry differ from species (Morus alba L., Morus nigra L. and Morus rubra L.). Phenolic compounds are prominent among the biologically active ingredients in mulberry, especially flavonoids, anthocyanins and phenolic acids. Epidemiologic studies suggest that mulberry contains a rich, effective chemical composition and a wide range of biological activity, such as antioxidant, anti-inflammatory, anti-tumor and so on. However, compared with other berries, there has been a lack of systematic research on mulberry, and this hinders its further expansion as a functional fruit. The main purpose of this review is to provide the latest data regarding the effective chemical constituents and pharmacological effects of mulberry to support its further therapeutic potential and health functions.

Effects of meteorin-like hormone on endocrine function of hypothalamo-hypophysial system and peripheral uncoupling proteins in rats

BACKGROUND

Meteorin-like hormone (Metrnl) is a peptide secreted from the adipose tissue and modulates the whole-body energy metabolism. Metrnl release into the circulation is influenced by obesity, cold exposure, and exercise. Thyroid hormones also exert many of their effects on metabolism through uncoupling proteins (UCPs). This study aimed to determine effect of Metrnl on hypothalamo-hypophysier-thyroid axis and energy metabolism and reveal the possible involvement of UCPs in this process.

METHODS AND RESULTS

Fourty male Sprague-Dawley rats were divided into 4 groups with 10 animals in each group: control, sham, 10 and 100 nM Metrnl. Hypothalamus, muscle, white adipose tissue (WAT) and brown adipose tissue (BAT) samples were collected to detect thyrotropin-releasing hormone (TRH), and UCP1 and UCP3 protein levels by western blot analysis. Serum thyroid-stimulating hormone (TSH), triiodothyronine (T3) and thyroxine (T4) hormone levels were determined by enzyme-linked immunosorbent assay. Central infusion of Metrnl caused significant increase in serum TSH, T3 and T4 levels compared to control (p < 0.05). After Metrnl treatment, there were significant increases in TRH in hypothalamus tissue, UCP1 in WAT and BAT; and UCP3 protein in the muscle tissue (p < 0.05).

CONCLUSIONS

The findings that Metrnl induced increases in the peripheral UCPs and hypothalamus-pituitary-thyroid axis hormones implicate a role for this hormone in body energy homeostasis through UCP-mediated mechanisms.

Intracerebroventricular asprosin administration strongly stimulates hypothalamic-pituitary-testicular axis in rats

Asprosin, a protein-based secretary product of white adipose tissue, stimulates appetite hepatic glucose production. It crosses blood-brain barrier and stimulates appetite center and causes sperm chemotaxis but exact role of this endogenous agent is not completely known. This study was conducted to investigate possible effects of central asprosin infusion on the hormones involved in the hypothalamic-pituitary-testicular (HPT) axis and sperm cells. Spraque Dawley male rats were divided into four groups; control, sham, low asprosin (34) and high asprosin (68 nM) groups, (n = 10 for each group). Control group remain intact while a brain infusion kit was placed in the lateral ventricles of the rats in the sham group (artificial cerebrospinal fluid) and asprosin (34 and 68 nM) was infused for 14 days. At the end of the experiment, the hypothalamus, blood, and epididymis tissues of the rats were collected. Gonadotropin-releasing hormone (GnRH) mRNA and tissue protein levels were determined in the hypothalamus tissue by RT-PCR and Western Blot methods. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were examined using the ELISA method from blood samples and sperm cells were examined in the epididymis tissue. GnRH mRNA and protein expressions of asprosin administered groups were higher than control and sham groups (p < 0.05). Asprosin infusion was also found to increase serum FSH, LH, and testosterone levels (p < 0.05). In addition, sperm density, motility, and progressive movement were observed to increase in asprosin administered groups (p < 0.05). This study suggests that central asprosin stimulate the HPT axis and also epididymis tissue. Our results implicates potential role for asprosin in male infertility.
