Exploring the anti-inflammatory and cytotoxic effects of Valeriana tuberosa L. constituents: Integrating in vitro and in silico studies. Fitoterapia 2025; 184:106604. [PMID: 40345339 DOI: 10.1016/j.fitote.2025.106604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2025] [Revised: 04/10/2025] [Accepted: 05/06/2025] [Indexed: 05/11/2025]
Abstract
Valeriana tuberosa L. yielded four new iridoids, valtuberoside I-IV (1-3 and 15), along with 13 known secondary metabolites via activity-directed fractionation. Compounds were characterized by NMR and HRESIMS. EtOH extract, fractions, and isolates were evaluated for their inhibition on nitric oxide (NO) release in LPS-induced RAW 264.7 cells. Compounds 3, 4, 6, 8, 9, 11, 13, 16, and 17 exhibited anti-inflammatory activity by inhibiting the release of NO (IC50 43.44-95.71 μM), and their mode of actions were elucidated by ELISA, Western blot, qPCR, immunostaining techniques and supported by molecular modelling studies. Compounds 8, 9, 11, 13, and 17 showed significant reduction in TNF-α, IL-1β, IL-6, PGE2, and COX-2 enzyme production, while 9 and 13 decreased iNOS protein expression in RAW 264.7 cells. Compound 13 exhibited remarkable inhibition on pro-inflammatory markers, cox-2 gene expression and translocation of NF-κB to the nuclear region. Moreover, it had the most favourable interaction (ds: -6.46 kcal/mol) with iNOS in in silico analyses. The cytotoxic activities of the most active isolates against MCF-7, MDA-MB-231, U87, A172, MIA PaCa-2, PANC-1, Mahlavu, and Hep3B cancer cell lines were assessed using CCK8 assay and their cell death mechanisms were unveiled via Apoptosis/Necrosis Assay Kit. Compound 8 had significant cytotoxic activity against MIA PaCa-2 (IC50 23.7 μM) and Hep3B (IC50 25.4 μM) cancer cell lines, via arresting cell cycle especially in G2/M phase and triggering the apoptotic pathway. These findings indicated that 8 and 13 deserve further in vivo assays on the way to discover new potential drug leads.

Abstract
In recent years, marine natural products (MNPs) have emerged as crucial sources of lead compounds for the advancement of anti-inflammatory drugs due to their abundant diversity, complexity, and distinctiveness. Inflammatory microenvironments (IMEs) are pervasive pathological features in the etiology of various chronic diseases, referring to the localized milieu or ecosystem where inflammatory responses occur, and they play a pivotal role in the onset and progression of inflammatory diseases. Uncontrolled IMEs can lead to dysregulation of inflammatory mediators within signaling pathways, thereby exerting detrimental effects on human health and even contributing to the development of inflammatory diseases such as cancer. Currently, inflammation treatment predominantly relies on chemical drugs. Nevertheless, these existing therapies are constrained by their numerous side effects and slow remission of symptoms. Consequently, there is an urgent need for the discovery and development of new drugs that exhibit minimal side effects while exerting potent anti-inflammatory effects. This article extensively explored the activities and mechanisms of MNPs (covering studies from 2010 to 2024) regulating key signaling pathways and inflammatory mediators in the IME, which establishes a theoretical basis for the further development of anti-inflammatory drugs.

Abstract
Intracerebral hemorrhage (ICH) is a common cerebrovascular disease characterized by a high incidence, disability rate, and mortality. Epigallocatechin gallate (EGCG), a key catechin compound found in green tea, has received increasing attention for its potential neuroprotective and therapeutic effects in neurological disorders. Studies have indicated that EGCG may influence various signaling pathways and molecular targets, including the inhibition of oxidative stress, reduction of inflammatory responses, suppression of cell apoptosis, regulation of cell survival, and enhancement of autophagy. Although the exact mechanism of action of EGCG is not fully understood, it has become a focal point of research in various disciplines due to its promising potential. This study aims to investigate the effects of EGCG on oxidative stress, iron deposition, and cell apoptosis in rats with ICH, as well as to uncover the underlying mechanisms. An ICH rat model was created to simulate cerebral hemorrhage, while an in vitro model utilizing primary cortical neurons was developed. The neurons were pre-treated with EGCG before being exposed to Erastin and RSL3 to induce iron death. The levels of oxidative stress, iron deposition, and cell apoptosis were evaluated in both models. In the ICH model, EGCG was discovered to enhance the activation of the Keap1/P62/Nrf2 signaling pathway in both in vivo and in vitro studies. Furthermore, EGCG significantly elevated the levels of GPX4 and XCT proteins, as well as the nuclear expression of Nrf2. It was noted that the Nrf2 inhibitor ML385 partially decreased the expression of these proteins. Through the activation of the Keap1/P62/Nrf2 pathway, EGCG inhibits inflammation, oxidative stress and iron deposition in rats with cerebral hemorrhage. EGCG inhibits oxidative stress, iron deposition and apoptosis in rats with ICH by activating Keap1/P62/Nrf2 pathway.

Zhang A, Cong L, Nan C, Zhao Z, Liu L. 3D biological scaffold delivers Bergenin to reduce neuroinflammation in rats with cerebral hemorrhage. J Transl Med 2024; 22:946. [PMID: 39420402 PMCID: PMC11484212 DOI: 10.1186/s12967-024-05735-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2024] [Accepted: 10/03/2024] [Indexed: 10/19/2024] Open
Abstract
BACKGROUND Intracerebral hemorrhage (ICH) is a severe form of stroke characterized by high incidence and mortality rates. Currently, there is a significant lack of effective treatments aimed at improving clinical outcomes. Our research team has developed a three-dimensional (3D) biological scaffold that incorporates Bergenin, allowing for the sustained release of the compound. METHODS This 3D biological scaffold was fabricated using a combination of photoinitiator, GEMA, silk fibroin, and decellularized brain matrix (dECM) to encapsulate Bergenin through advanced 3D bioprinting techniques. The kinetics of drug release were evaluated through both in vivo and in vitro studies. A cerebral hemorrhage model was established, and a 3D biological scaffold containing Bergenin was transplanted in situ. Levels of inflammatory response, oxidative stress, and apoptosis were quantified. The neurological function of rats with cerebral hemorrhage was assessed on days 1, 3, and 5 using the turning test, forelimb placement test, Longa score, and Bederson score. RESULTS The 3D biological scaffold incorporating Bergenin significantly enhances the maintenance of drug concentration in the bloodstream, leading to a marked reduction in inflammatory markers such as IL-6, iNOS, and COX-2 levels in a cerebral hemorrhage model, primarily through the inhibition of the NF-κB pathway. Additionally, the scaffold effectively reduces the expression of hypoxia-inducible factor 1-alpha (HIF-1α) in primary cultured astrocytes, which in turn decreases the production of reactive oxygen species (ROS) and inhibits IL-6 production induced by hemin. Subsequent experiments reveal that the 3D biological scaffold containing Bergenin promotes the activation of the Nrf-2/HO-1 signaling pathway, both in vivo and in vitro, thereby preventing cell death. Moreover, the application of this 3D biological scaffold has been demonstrated to improve drug retention in the bloodstream. CONCLUSION This strategy effectively mitigates inflammation, oxidative stress, and cell death in rats with cerebral hemorrhage by inhibiting the NF-κB pathway while concurrently activating the Nrf-2/HO-1 pathway.

Comp Biochem Physiol C Toxicol Pharmacol 2024; 283:109953.

Abstract
The intertidal organism Tegillarca granosa can survive under frequent hypoxia/reoxygenation (H/R) exposure. Sulfides as accompanying products in benthic hypoxic environments, may play an important regulatory role, but the mechanisms are not well understood. This article investigated the physiological and molecular changes of T. granosa after adding different concentrations of sulfides (0.1, 0.5, 1 mM) at 72 h into a 120-h exposure to hypoxia, as well as the recovery state of 24 h of reoxygenation. The results indicated that H/R stress induces ROS production and mild mitochondrial depolarization in clams, and sulfide can participate in its regulation. Among them, a low concentration of sulfide up-regulated glutathione content and alternative oxidase activity, maintained the stability of antioxidant enzymes, and up-regulated the expression of the survival genes XIAP/BCL-xl which mediate cell survival via the NFκB signaling pathway. High concentrations of sulfide had a significant inhibitory effect on the p38/MPAK pathway and inhibited intrinsic apoptosis caused by ROS accumulation during reoxygenation. Taken together, our study suggested that different concentrations of sulfides are involved in regulating the endogenous apoptosis of clams during H/R.

Abstract
Cancers are currently the major cause of mortality in the world. According to previous studies, matrix metalloproteinases (MMPs) have an impact on tumor cell proliferation, which could lead to the onset and progression of cancers. Therefore, regulating the expression and activity of MMPs, especially MMP-2 and MMP-9, could be a promising strategy to reduce the risk of cancers. Various studies have tried to investigate and understand the pathophysiology of cancers to suggest potent treatments. In this review, we summarize how natural products from marine organisms and plants, as regulators of MMP-2 and MMP-9 expression and enzymatic activity, can operate as potent anticancer agents.

Abstract
Gastric cancer (GC) is one of the severe malignancies with high incidence and mortality, especially in Eastern Asian countries. Significant advancements have been made in diagnosing and treating GC over the past few decades, resulting in tremendous improvements in patient survival. In recent years, traditional Chinese medicine (TCM) has garnered considerable attention as an alternative therapeutic approach for GC due to its multicomponent and multitarget characteristics. Consequently, natural products found in TCM have attracted researchers' attention, as growing evidence suggests that these natural products can impede GC progression by regulating various biological processes. Nevertheless, their molecular mechanisms are not systematically uncovered. Here, we review the major signaling pathways involved in GC development. Additionally, clinical GC samples were analyzed. Moreover, the anti-GC effects of natural products, their underlying mechanisms and potential targets were summarized. These summaries are intended to facilitate further relevant research, and accelerate the clinical applications of natural products in GC treatment.

Abstract
Hypopharyngeal carcinoma is notorious for its poor prognosis among all head and neck cancers, posing a persistent challenge in clinical settings. The continuous hyperactivation of the NFκB signalling pathway has been noted in various cancer types, including hypopharyngeal carcinoma. In our quest to develop a novel drug that targets hypopharyngeal cancer via the NFκB pathway, we employed curcumin, a well-known lead compound, and performed chemical modifications to create a mono-carbonyl analogue called L42H17. This compound exhibited exceptional stability and displayed an enhanced binding affinity to myeloid differentiation protein 2 (MD2). Consistent with expectations, L42H17 demonstrated the ability to inhibit TNF-α-induced phosphorylation of inhibitor of κB (IκB) kinase (IKK), prevent IκB degradation, and subsequently impede NFκB-p65 nuclear translocation in hypopharyngeal cancer cells. Additionally, L42H17 exhibited a remarkable capacity to induce cell cycle arrest at the G2-M phase by inactivating the cdc2-cyclin B1 complex. Moreover, it facilitated cell apoptosis by reducing Bcl-2 levels and augmenting the expression of cle-PARP and cle-caspase3. Importantly, we observed a significant enhancement in the anti-cancer efficacy of L42H17 in a patient-derived tumour xenograft (PDTX) model of hypopharyngeal carcinoma. In conclusion, our findings strongly suggest that L42H17 holds promise as a potential candidate drug for the treatment of hypopharyngeal carcinoma in the future.

Abstract
Localized provoked vulvodynia (LPV) affects ∼14 million people in the US (9% of women), destroying lives and relationships. LPV is characterized by chronic pain (>3 months) upon touch to the vulvar vestibule, which surrounds the vaginal opening. Many patients go months or years without a diagnosis. Once diagnosed, the treatments available only manage the symptoms of disease and do not correct the underlying problem. We have focused on elucidating the underlying mechanisms of chronic vulvar pain to speed diagnosis and improve intervention and management. We determined the inflammatory response to microorganisms, even members of the resident microflora, sets off a chain of events that culminates in chronic pain. This agrees with findings from several other groups, which show inflammation is altered in the painful vestibule. The vestibule of patients is acutely sensitive to inflammatory stimuli to the point of being deleterious. Rather than protect against vaginal infection, it causes heightened inflammation that does not resolve, which coincides with alterations in lipid metabolism that favor production of proinflammatory lipids and not pro-resolving lipids. Lipid dysbiosis in turn triggers pain signaling through the transient receptor potential vanilloid subtype 4 receptor (TRPV4). Treatment with specialized pro-resolving mediators (SPMs) that foster resolution reduces inflammation in fibroblasts and mice and vulvar sensitivity in mice. SPMs, specifically maresin 1, act on more than one part of the vulvodynia mechanism by limiting inflammation and acutely inhibiting TRPV4 signaling. Therefore, SPMs or other agents that target inflammation and/or TRPV4 signaling could prove effective as new vulvodynia therapies.

Abstract
The conversion of skeletal muscle fiber from fast-twitch to slow-twitch is crucial for sustained contractile and stretchable events, energy homeostasis, and anti-fatigue ability. The purpose of our study was to explore the mechanism and effects of garcinol on the regulation of skeletal muscle fiber type transformation. Forty 21-day-old male C57/BL6J mice (n = 10/diet) were fed a control diet or a control diet plus garcinol at 100 mg/kg (Low Gar), 300 mg/kg (Mid Gar), or 500 mg/kg (High Gar) for 12 weeks. The tibialis anterior (TA) and soleus muscles were collected for protein and immunoprecipitation analyses. Dietary garcinol significantly downregulated (p < 0.05) fast myosin heavy chain (MyHC) expression and upregulated (p < 0.05) slow MyHC expression in the TA and soleus muscles. Garcinol significantly increased (p < 0.05) the activity of peroxisome proliferator-activated receptor gamma co-activator 1α (PGC-1α) and markedly decreased (p < 0.05) the acetylation of PGC-1α. In vitro and in vivo experiments showed that garcinol decreased (p < 0.05) lactate dehydrogenase activity and increased (p < 0.05) the activities of malate dehydrogenase and succinic dehydrogenase. In addition, the results of C2C12 myotubes showed that garcinol treatment increased (p < 0.05) the transformation of glycolytic muscle fiber to oxidative muscle fiber by 45.9%. Garcinol treatment and p300 interference reduced (p < 0.05) the expression of fast MyHC but increased (p < 0.05) the expression of slow MyHC in vitro. Moreover, the acetylation of PGC-1α was significantly decreased (p < 0.05). Garcinol promotes the transformation of skeletal muscle fibers from the fast-glycolytic type to the slow-oxidative type through the p300/PGC-1α signaling pathway in C2C12 myotubes.

[PMID: 36209270 PMCID: PMC9547882 DOI: 10.1038/s41392-022-01190-w] [Citation(s) in RCA: 145] [Impact Index Per Article: 48.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Revised: 08/14/2022] [Accepted: 09/07/2022] [Indexed: 11/23/2022] Open
Abstract
Gastric cancer (GC) ranks fifth in global cancer diagnosis and fourth in cancer-related death. Despite tremendous progress in diagnosis and therapeutic strategies and significant improvements in patient survival, the low malignancy stage is relatively asymptomatic and many GC cases are diagnosed at advanced stages, which leads to unsatisfactory prognosis and high recurrence rates. With the recent advances in genome analysis, biomarkers have been identified that have clinical importance for GC diagnosis, treatment, and prognosis. Modern molecular classifications have uncovered the vital roles that signaling pathways, including EGFR/HER2, p53, PI3K, immune checkpoint pathways, and cell adhesion signaling molecules, play in GC tumorigenesis, progression, metastasis, and therapeutic responsiveness. These biomarkers and molecular classifications open the way for more precise diagnoses and treatments for GC patients. Nevertheless, the relative significance, temporal activation, interaction with GC risk factors, and crosstalk between these signaling pathways in GC are not well understood. Here, we review the regulatory roles of signaling pathways in GC potential biomarkers, and therapeutic targets with an emphasis on recent discoveries. Current therapies, including signaling-based and immunotherapies exploited in the past decade, and the development of treatment for GC, particularly the challenges in developing precision medications, are discussed. These advances provide a direction for the integration of clinical, molecular, and genomic profiles to improve GC diagnosis and treatments.

Abstract
Intestinal mucositis is a clinically related adverse reaction of antitumor treatment. Majority of patients receiving high-dose chemical therapy, radiotherapy, and bone-marrow transplant suffer from intestinal mucositis. Clinical manifestations of intestinal mucositis mainly include pain, body-weight reduction, inflammatory symptom, diarrhea, hemoproctia, and infection, which all affect regular nutritional input and enteric function. Intestinal mucositis often influences adherence to antitumor treatment because it frequently restricts the sufferer’s capacity to tolerate treatment, thus resulting in schedule delay, interruption, or premature suspension. In certain circumstances, partial and general secondary infections are found, increasing the expenditures on medical care and hospitalization. Current methods of treating intestinal mucositis are provided, which do not always counteract this disorder. Against this background, novel therapeutical measures are extremely required to prevent and treat intestinal mucositis. Plant-derived natural compounds have lately become potential candidates against enteric injury ascribed to the capacity to facilitate mucosal healing and anti-inflammatory effects. These roles are associated with the improvement of intestinal mucosal barrier, suppression of inflammatory response and oxidant stress, and modulation of gut microflora and immune system. The present article aims at systematically discussing the recent progress of plant-derived natural compounds as promising treatments for intestinal mucositis.

Abstract
Bladder cancer (BC) is a primary source of malignancy-associated death, and the mortality rate is high due to its prevalence of metastasis. Corilagin (CLG), a bioactive constituent of numerous medicinal plants, exerts assorted pharmacological actions comprising anti-cancer, apoptotic, anti-inflammatory, and hepatoprotective. CLG possesses a substantial anti-tumor prospective and less noxiousness in normal cells in vitro. However, the molecular mechanisms of CLG on BC cells are not studied well. The current research explored the molecular process intricate in the anticancer and anti-proliferative actions of CLG on the relocation of BC cells T24 and TSGH 8301. The cytotoxicity, apoptosis, adhesion, and migration of CLG on BC cells T24 and TSGH 8301 were evaluated by MTT assay, DAPI, Rh-123, cell adhesion, and cell migration assay. The results point out that CLG inhibits the viability, adhesion, movement, incursion, and inflammation, whereas persuades BC cells apoptosis in a concentration-dependent mode. Besides, CLG treated with T24 and TSGH-8301 cells subdue inflammatory and PI3K/Akt signaling pathways. CLG is accomplished of impeding BC cell migration, invasion, and metastasis through the repression of the NF-κB mediated P13K/Akt signaling. Our findings offer a unique vision into the demonstration of the anti-cancer potential of CLG on BC cells.

Epigallocatechin Gallate Protects against Hypoxia-Induced Inflammation in Microglia via NF-κB Suppression and Nrf-2/HO-1 Activation. Int J Mol Sci 2022; 23:ijms23074004.

Abstract
Hypoxia-induced neuroinflammation in stroke, neonatal hypoxic encephalopathy, and other diseases subsequently contributes to neurological damage and neuronal diseases. Microglia are the primary neuroimmune cells that play a crucial role in cerebral inflammation. Epigallocatechin gallate (EGCG) has a protective antioxidant and anti-inflammatory effects against neuroinflammation. However, the effects of EGCG on hypoxia-induced inflammation in microglia and the underlying mechanism remain unclear. In this study, we investigated whether EGCG might have a protective effect against hypoxia injury in microglia by treatment with CoCl2 to establish a hypoxic model of BV2 microglia cells following EGCG pre-treatment. An exposure of cells to CoCl2 caused an increase in inflammatory mediator interleukin (IL)-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2 expression, which were significantly ameliorated by EGCG via inhibition of NF-κB pathway. In addition, EGCG attenuated the expression of hypoxia-inducible factor (HIF)-1α and the generation of ROS in hypoxic BV2 cells. Furthermore, the suppression of hypoxia-induced IL-6 production by EGCG was mediated via the inhibition of HIF-1α expression and the suppression of ROS generation in BV2 cells. Notably, EGCG increased the Nrf-2 levels and HO-1 levels in the presence of CoCl2. Additionally, EGCG suppressed hypoxia-induced apoptosis of BV2 microglia with cleavage of poly (ADP-ribose) polymerase (PARP) and caspase-3. In summary, EGCG protects microglia from hypoxia-induced inflammation and oxidative stress via abrogating the NF-κB pathway as well as activating the Nrf-2/HO-1 pathway.

In Silico and In Vitro Screening of 50 Curcumin Compounds as EGFR and NF-κB Inhibitors. Int J Mol Sci 2022; 23:ijms23073966. [PMID: 35409325 PMCID: PMC9000198 DOI: 10.3390/ijms23073966] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 03/28/2022] [Accepted: 03/29/2022] [Indexed: 02/05/2023] Open
Abstract
The improvement of cancer chemotherapy remains a major challenge, and thus new drugs are urgently required to develop new treatment regimes. Curcumin, a polyphenolic antioxidant derived from the rhizome of turmeric (Curcuma longa L.), has undergone extensive preclinical investigations and, thereby, displayed remarkable efficacy in vitro and in vivo against cancer and other disorders. However, pharmacological limitations of curcumin stimulated the synthesis of numerous novel curcumin analogs, which need to be evaluated for their therapeutic potential. In the present study, we calculated the binding affinities of 50 curcumin derivatives to known cancer-related target proteins of curcumin, i.e., epidermal growth factor receptor (EGFR) and nuclear factor κB (NF-κB) by using a molecular docking approach. The binding energies for EGFR were in a range of −12.12 (±0.21) to −7.34 (±0.07) kcal/mol and those for NF-κB ranged from −12.97 (±0.47) to −6.24 (±0.06) kcal/mol, indicating similar binding affinities of the curcumin compounds for both target proteins. The predicted receptor-ligand binding constants for EGFR and curcumin derivatives were in a range of 0.00013 (±0.00006) to 3.45 (±0.10) µM and for NF-κB in a range of 0.0004 (±0.0003) to 10.05 (±4.03) µM, indicating that the receptor-ligand binding was more stable for EGFR than for NF-κB. Twenty out of 50 curcumin compounds showed binding energies to NF-κB smaller than −10 kcal/mol, while curcumin as a lead compound revealed free binding energies of >−10 kcal/mol. Comparable data were obtained for EGFR: 15 out of 50 curcumin compounds were bound to EGFR with free binding energies of <−10 kcal/mol, while the binding affinity of curcumin itself was >−10 kcal/mol. This indicates that the derivatization of curcumin may indeed be a promising strategy to improve targe specificity and to obtain more effective anticancer drug candidates. The in silico results have been exemplarily validated using microscale thermophoresis. The bioactivity has been further investigated by using resazurin cell viability assay, lactate dehydrogenase assay, flow cytometric measurement of reactive oxygen species, and annexin V/propidium iodide assay. In conclusion, molecular docking represents a valuable approach to facilitate and speed up the identification of novel targeted curcumin-based drugs to treat cancer.

Abstract
Xanthorrhizol (XNT) is a sesquiterpenoid agent isolated from Curcuma xanthorrhiza; It is known to exhibit various pharmacological activities including anti-cancer. We investigated the anti-cell proliferative and proapoptotic effects of XNT on Non-small cell carcinoma (A549) cells were analyzed by the generation of reactive oxygen species (ROS), alteration of mitochondrial membrane potential (ΔΨm), oxidative DNA damage, and apoptosis morphological changes were explored by Hoechst and AO/EtBr staining. Our study demonstrated that XNT treatment significantly reduced the viability of A549 cells in a concentration-dependent manner. We observed that XNT-induced oxidative stress-mediated apoptotic cell death by increasing intracellular ROS generation, depleting antioxidant levels, enhancing lipid peroxidation, increased apoptotic morphological changes, and % of DNA damage on human lung cancer cells. Furthermore, we observed that the XNT induce apoptosis through inhibits phosphorylation of PI3K, AKTand inhibit NF-κBp65 transcriptional signaling activity. In addition, XNT treatment alters the ΔΨm, thereby induces apoptosis was closely coordinated with the induction of pro-apoptotic markers Bax, Bad, caspase- 3, 9 and cytochrome c, and suppression of anti-apoptotic (Bcl-2, Bcl-XL) protein expression. According to our results, XNT-inducing apoptosis in A549 cells by causing oxidative damage and modulating apoptotic signaling events. Finally, XNT-induced apoptotic cell death was confirmed by the TUNEL assay. Therefore, XNT might be used as a chemotherapeutic agent for the treatment of lung cancer.

Abstract
Localized provoked vulvodynia (LPV) is the most common cause of chronic dyspareunia in premenopausal women, characterized by pain with light touch to the vulvar vestibule surrounding the vaginal opening. The devastating impact of LPV includes sexual dysfunction, infertility, depression, and even suicide. Yet, its etiology is unclear. No effective medical therapy exists; surgical removal of the painful vestibule is the last resort. In LPV, the vestibule expresses a unique inflammatory profile with elevated levels of pro-nociceptive proinflammatory mediators prostaglandin E2 (PGE2) and interleukin-6 (IL-6), which are linked to lower mechanical sensitivity thresholds. Specialized pro-resolving mediators (SPMs), lipids produced endogenously within the body, hold promise as an LPV treatment by resolving inflammation without impairing host defense. Ten of 13 commercially available SPMs reduced IL-6 and PGE2 production by vulvar fibroblasts, administered either before or after inflammatory stimulation. Using a murine vulvar pain model, coupling proinflammatory mediator quantification with mechanical sensitivity threshold determination, topical treatment with the SPM, maresin 1, decreased sensitivity and suppressed PGE2 levels. Docosahexaenoic acid, a precursor of maresin 1, was also effective in reducing PGE2 in vulvar fibroblasts and rapidly restored mouse sensitivity thresholds. Overall, SPMs and their precursors may be a safe and efficacious for LPV. Perspective: Vulvodynia, like many pain conditions, is difficult to treat because disease origins are incompletely understood. Here, we applied our knowledge of more recently discovered vulvodynia disease mechanisms to screen novel therapeutics. We identified several specialized pro-resolving mediators as likely potent and safe for treating LPV with potential for broader application.

Abstract
BACKGROUND Curcumin is a major active principle of Curcuma longa. There are more than 1700 citations in the Medline, reflecting various biological effects of curcumin. Most of these biological activities are associated with the antioxidant, anti-inflammatory and antitumor activity of the molecule. Several reports suggest various targets of natural curcumin that include growth factors, growth factor receptor, cytokines, enzymes and gene regulators of apoptosis. This review focuses on the improved curcumin derivatives that target the cancer and inflammation. METHODOLOGY In this present review, we explored the anticancer drugs with curcumin-based drugs under pre-clinical and clinical studies with critical examination. Based on the strong scientific reports of patentable and non-patented literature survey, we have investigated the mode of the interactions of curcumin-based molecules with the target molecules. RESULTS Advanced studies have added new dimensions of the molecular response of cancer cells to curcumin at the genomic level. However, poor bioavailability of the molecule seems to be the major limitation of the curcumin. Several researchers have been involved to improve the curcumin derivatives to overcome this limitation. Sufficient data of clinical trials to various cancers that include multiple myeloma, pancreatic cancer and colon cancer, have also been discussed. CONCLUSION The detailed analysis of the structure-activity relationship (SAR) and common synthesis of curcumin-based derivatives have been discussed in the review. Utilising the predictions of in silico coupled with validation reports of in vitro and in vivo studies have concluded many targets for curcumin. Among them, cancer-related inflammation genes regulating curcumin-based molecules are a very promising target to overcome hurdles in the multimodality therapy of cancer.

Abstract
AIM The rapid growth, morbidity and mortality of prostate cancer, and the lack of effective treatment have attracted great interest of researchers to find novel cancer therapies aiming at the effect of gossypin on cell proliferation and apoptosis of PC-3 cells. METHODS The effect of gossypin on cell viability was determined using MTT assay at 5-100μg/ml and cisplatin (50μM) in a time-dependent manner in PC-3 cell lines. The expression levels of caspase-3 (CASP3) and caspase-9 (CASP9) for apoptosis and Nuclear Factor Kappa B (NFKB1) for survival, inflammation, and growth were evaluated by real-time PCR. Hoechst staining was used to analyze apoptosis. RESULTS Gossypin showed an anti-proliferative effect on PC3 cell line in a time- and dose-dependent manner. In addition, gossypin led to a significant increase in apoptosis genes (CASP3, CASP9) when compared to control while it caused a decrease in the level of NFKB1, which is accepted as apoptosis inhibitor (p<0.05) (cisplatin-like). Gossypin 50 and 100μM significantly induced apoptotic mechanism in PC-3 cells. However, no apoptotic or commonly stained nuclei have been observed in control group cells. CONCLUSION The results indicated that gossypin can be defined as a promising anticancer agent for PC-3 human prostate cancer cell line.

Abstract
Natural compounds, such as paclitaxel and camptothecin, have great effects on the treatment of tumors. Such natural chemicals often achieve anti-tumor effects through a variety of mechanisms. Therefore, it is of great significance to conduct further studies on the anticancer mechanism of natural anticancer agents to lay a solid foundation for the development of new drugs. Myricetin, originally isolated from Myrica nagi, is a natural pigment of flavonoids that can inhibit the growth of cancer cells (such as liver cancer, rectal cancer, skin cancer and lung cancer, etc.). It can regulate many intracellular activities (such as anti-inflammatory and blood lipids regulation) and can even be bacteriostatic. The purpose of this paper is to outline the molecular pathways of the anticancer effects of myricetin, including the effect on cancer cell death, proliferation, angiogenesis, metastasis and cell signaling pathway.

Abstract
Oxidative damage in cells induced by reactive oxygen species (ROS) is a main factor in diabetes mellitus diseases progression. The composition of anthocyanins from Padus racemosa (APR) and the protective effects of APR on H2 O2 -induced rat insulinoma (INS-1) cells damage and streptozocin (STZ)-induced diabetes mice were investigated in this study. The main components of APR were cyanidin-cyanidin glucosyl-rutinoside, cyanidin-cyanidin xylosyl-rutinoside, cyanidin-xylosyl-glucoside and cyanidin-rutinoside, which were determined by liquid chromatography-mass spectrometry (LC/MS). APR could scavenge the 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl radical and superoxide radical in vitro. ROS level was decreased and the cell viability was increased in INS-1 cells after treated with APR. Cell apoptosis induced by H2 O2 in INS-1 cells was decreased after incubation with APR. APR could decrease the phosphorylation of p38 and the nuclear translocation of p65, which indicated that APR could inhibit the activation of p38 Mitogen-activated protein kinase (MAPK) and Nuclear factor kappa B (NF-κB) cell signaling pathways. Meanwhile, APR could effectively reduce the blood glucose and blood lipid in STZ-induced diabetic mice. These results suggested that APR might be a potential agent for diabetes mellitus diseases treatment.

Abstract
BACKGROUND AND OBJECTIVE This study was aimed to elucidate the molecular mechanism of Momordica charantia (MCh), along with a standard drug prednisolone, in a rat model of colitis induced by trinitrobenzene sulfonic acid (TNBS). METHODS After the induction of the experimental colitis, the animals were treated with MCh (4 g/kg/day) for 14 consecutive days by intragastric gavage. The colonic tissue expression levels of C-C motif chemokine ligand 17 (CCL-17), interleukin (IL)-1β, IL-6, IL-23, interferon-γ (IFN-γ), nuclear factor kappa B (NF-kB), and tumor necrosis factor-α (TNF-α), were determined at both mRNA and protein levels to estimate the effect of MCh. Besides, colonic specimens were analyzed histopathologically after staining with hematoxylin and eosin. RESULTS The body weights from TNBS-instigated colitis rats were found to be significantly lower than untreated animals. Also, the IFN-γ, IL-1β, IL-6, Il-23, TNF-α, CCL-17, and NF-kB mRNA and protein levels were increased significantly from 1.86-4.91-fold and 1.46-5.50-fold, respectively, in the TNBS-instigated colitis group as compared to the control. Both the MCh and prednisolone treatment significantly reduced the bodyweight loss. It also restored the induced colonic tissue levels of IL-1β, IL-6, IFN-γ, and TNF-α to normal levels seen in untreated animals. These results were also supported with the histochemical staining of the colonic tissues from both control and treated animals. CONCLUSION The presented data strongly suggests that MCh has the anti-inflammatory effect that might be modulated through vitamin D metabolism. It is the right candidate for the treatment of UC as an alternative and complementary therapeutics.

Abstract
The recent advances in cancer immunotherapy confirm the crucial role of the immune system in cancer progression and treatment. Chronic inflammation and reduced immune surveillance are both features of the tumor microenvironment. Strategies aimed at reverting pro-tumor inflammation and stimulating the antitumor immune components are being actively searched, and the anticancer effects of many candidate drugs have been linked to their ability to modulate the immune system. Marine organisms constitute a rich reservoir of new bioactive molecules; some of them have already been exploited for pharmaceutical use, whereas many others are undergoing clinical or preclinical investigations for the treatment of different diseases, including cancer. In this review, we will discuss the immune-modulatory properties of marine compounds for their potential use in cancer prevention and treatment and as possible tools in the context of cancer immunotherapy.

Abstract
Phospholipase Cγ2 (PLCG2) has been implicated in the regulation of cell proliferation, transformation, and tumor growth. In this study, we investigate the mechanism of PLCG2 action using a short interference RNA (siRNA) method. The effects of PLCG2 on rat liver BRL-3A cells treated siRNA were studied by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT assay), bromodeoxyuridine (BrdU) labelling assay, flow cytometry method (FCM), quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The results showed when PLCG2 was reduced, cell vitality and proliferation rate were significantly decreased (p < .05 vs. control). FCM analysis showed that the number of cell division phase (G2 + M) was declined (p < .05 vs. control). RT-PCR and western blot revealed that the expression of signalling related genes NF-κB, FOS, JUN and ELK, target genes BCL2, CCNB1 and CCND1 were remarkably down-regulated in cells treated with PLCG2 siRNAs. Based on these results, we conclude PLCG2 plays an important role in rat liver cell proliferation via ERK and NF-κB pathway by regulating the expression of BCl2, MYC and CCND1.

Abstract
The indole-3-carbinol (I3C) displays anti-cancer/proliferative activities against human cancer cells. Cellular proliferation is an event associated with the progress and its continuation. This manifest is described by variation in expression and/or functions of genes that are related with cell cycle relevant proteins. The constitutive activation of several signal transduction pathways stimulates cells proliferation as well. The immediate stages in cancer development are accompanied by a fibrogenic response and the progression of the hypoxic environment is in favor of survival and proliferatory functions of cancer stem cells. A main part for prevention of in cancer cells death may manifest through altering cell metabolism. Cellular proliferation and metastasis are reported to be supported with increased generation of responsible hormones (in hormone dependent malignancies), and further promotion the angiogenesis, with epithelial to mesenchymal transition. This may be facilitated by progression of autophagy phenomenon, as well as via taking cues from neighboring stromal cells. Several signaling pathways in association with various factors specific for cellular viability, including hypoxia inducible factor 1, NF-κB, insulin-like growth factor 1 (IGF-1) receptor, Human foreskin fibroblasts (HFF-1), phosphoinositide 3 kinase/Akt, Wnt, cell cycle related protein, with androgen and estrogen receptor signaling are reported to be inhibited by I3C. These evidences, in association with bioinformatics data represent very important information for describing signaling pathways in parallel with molecular targets that may serve as markers for early diagnosis and/or critical targets for designing and development of novel therapeutic regimes alone or combined with drugs, to prevent tumor formation and further progression. In particular, I3C and DIM have been extensively investigated for their importance against numbers human cancers both in vitro and in vivo. We aimed the present manuscript, current study, to review anticancer properties and the miscellaneous mechanisms underlying the antitumorigenicity in an in-depth study for broadening the I3C treating marvel.

Abstract
Inflammatory and microenvironmental factors produced by cancer cells are thought to directly or indirectly promote cancer cell growth. Prostaglandins, including prostaglandin E2, have key roles as a microenvironment factor in influencing the development of tumors, and are produced by the rate limiting enzyme cyclooxygenase 2 (COX-2). In this study, we used canine melanoma cells treated with the proinflammatory cytokine interleukin 1β (IL-1β) and investigated the transcriptional factor nuclear factor-κB (NF-κB) signaling in IL-1β-induced COX-2 expression. IL-1β induced prostaglandin E2 release and COX-2 mRNA expression in a time- and dose-dependent manner. In the cells treated with the NF-κB inhibitors BAY11-7082 and TPC-1, IL-1β-mediated prostaglandin E2 release and COX-2 mRNA expression were inhibited. IL-1β also provoked phosphorylation of p65/RelA and p105/NF-κB1, which are members of the NF-κB families. The IL-1β-induced phosphorylation of p65 and p105 was attenuated in the presence of both NF-κB inhibitors. In melanoma cells transfected with siRNA of p65 or p105, IL-1β-mediated COX-2 mRNA expression was inhibited. These findings suggest that canonical activation of NF-κB signaling plays a crucial role for inflammatory states in melanoma cells.

Abstract
BACKGROUND Berberine is an alkaloid plant-based DNA intercalator that affects gene regulation, particularly expression of oncogenic and tumor suppressor proteins. The effects of berberine on different signaling proteins remains to be elucidated. The present study aimed to identify the effects of berberine against key oncogenic proteins in breast cancer cells. METHODS Molecular docking and molecular dynamics simulations were used for EGFR, p38, ERK1/2, and AKT. The effects of berberine and lapatinib on MAPK and PI3K pathways in MDA-MB231 and MCF-7 cells were evaluated using immunoflorescence assays, and the amounts of phosphorylated kinases were compared to total kinases after treating with different concentrations of berberine. RESULTS Simulations showed berberine accurately interacted with EGFR, AKT, P38, and ERK1/2 active sites in silico (scores = -7.57 to -7.92 Kcal/mol) and decreased the levels of active forms of corresponding enzymes in both cell lines; however, berberine binding to p38 showed less stability. Cytotoxicity analysis indicated that MDA-MB231 cells were resistant to berberine compared to MCF-7 cells [72 h IC50 = 50 versus 15 μM, respectively). Also, lapatinib strongly activated AKT but suppressed EGFR in MDA-MB231 cells. The activity of EGFR, AKT, P38, and ERK1/2 were affected by berberine; however, berberine dramatically reduced EGFR and AKT phosphorylation. CONCLUSION By way of its multikinase inhibitory effects, berberine might be a useful replacement for lapatinib, an EGFR inhibitor which can cause acquired drug resistance in patients.

Abstract
Dehydroeffusol (DHE) is a phenanthrene isolated from the Chinese medicinal plant Juncus effusus. Biological evaluation of DHE reveals in vitro and in vivo anticancer effects. We performed a shotgun proteomic analysis using liquid chromatography-tandem mass spectrometry to investigate the changes in the protein profiles in cancer cells upon DHE treatment. DHE affected cancer-associated signaling pathways, including NF-κB, β-catenin, and endoplasmic reticulum stress. Through quantitative pathway and key node analysis of the proteomics data, activating transcription factor 2 (ATF-2) and c-Jun kinase (JNK) were found to be the key components in DHE's modulated biological pathways. Based on the pathway analysis as well as chemical similarity to estradiol, DHE is proposed to be a phytoestrogen. The proteomic, bioinformatic, and chemoinformatic analyses were further verified with individual cell-based experiments. Our study demonstrates a workflow for identifying the mechanisms of action of DHE through shotgun proteomic analysis.

Abstract
B cell activating factor (BAFF) is an important cytokine for the maintenance of B cell development, survival and homeostasis. BAFF/BAFF-R could directly activate nuclear factor kappa B (NF-κB) pathway. Tumour necrosis factor receptor-associated factors (TRAFs) are key regulatory proteins in NF-κB signaling pathways. TRAF1 enhances the activation of tumor necrosis factor receptor 2 (TNF-R2) induced by NF-κB. TRAF2 and TRAF3 signal adapters act cooperatively to control the maturation and survival signals mediated by BAFF receptor. TRAF5 is most homologous to TRAF3, as well as most functionally similar to TRAF2. TRAF6 is also required for the BAFF-mediated activation of NF-κB signal pathway. TRAF7 is involved in signal transduction pathways that lead either to activation or repression of NF-κB transcription factor. In this article, we reviewed the roles of TRAFs in NF-κB signaling pathway mediated by BAFF.

Abstract
Myricetin is a flavonoids compound extracted from edible myrica rubra. We aimed to evaluate the efficacy of Myricetin on colonic chronic inflammation and inflammation-driven tumorigenesis in mice. Myricetin was administrated by gavage for 4 consecutive weeks. Mice were sacrificed and the number of colonic polyps was counted. Myricetin significantly inhibited AOM/DSS-induced colitis and colorectal tumorigenesis. Myricetin prevented the incidence of colorectal tumorigenesis and reduced the size of colorectal polyps. Histopathologic analysis showed that Myricetin could attenuate the degree of colonic inflammation and colorectal tumorigenesis. Further analysis showed that Myricetin strongly reduced the levels of inflammatory factors TNF-α, IL-1β, IL-6, NF-κB, p-NF-κB, cyclooxygenase-2 (COX-2), PCNA and Cyclin D1 in the colonic tissues as analyzed by the assays of immunohistochemical staining, Western blotting and Q-RT-PCR. Our results demonstrated that Myricetin possesses the biological activities of chemoprevention colonic chronic inflammation and inflammation-driven tumorigenesis. We suggest that Myricetin could be developed as a promising chemopreventive drug for reducing the risk of colorectal cancer.

Abstract
Carcinogenesis has a multifactorial etiology, and the underlying molecular pathogenesis is still not entirely understood, especially for eye cancers. Primary malignant intraocular neoplasms are relatively rare, but delayed detection and inappropriate management contribute to poor outcomes. Conventional treatment, such as orbital exenteration, chemotherapy, or radiotherapy, alone results in high mortality for many of these malignancies. Recent sequential multimodal therapy with a combination of high-dose chemotherapy, followed by appropriate surgery, radiotherapy, and additional adjuvant chemotherapy has helped dramatically improve management. Transcription factors are proteins that regulate gene expression by modulating the synthesis of mRNA. Since transcription is a dominant control point in the production of many proteins, transcription factors represent key regulators for numerous cellular functions, including proliferation, differentiation, and apoptosis, making them compelling targets for drug development. Natural compounds have been studied for their potential to be potent yet safe chemotherapeutic drugs. Since the ancient times, plant-derived bioactive molecules have been used to treat dreadful diseases like cancer, and several refined pharmaceutics have been developed from these compounds. Understanding targeting mechanisms of oncogenic transcription factors by natural products can add to our oncologic management toolbox. This review summarizes the current findings of natural products in targeting specific oncogenic transcription factors in various types of eye cancer.

Abstract
Proteasome inhibition has recently emerged as a clinically effective anticancer therapeutic approach. The first proteasome inhibitor, bortezomib (Velcade, PS-341), and new proteasome inhibitors including ixazomib have become more important in the development of targeted cancer therapies. Under physiological conditions, MLN9708 (ixazomib citrate), the stable citrate ester drug substance, hydrolyzes rapidly to MLN2238 (ixazomib), the biologically active boronic acid. It is a second-generation proteasome inhibitor, similar to the well-known proteasome inhibitor bortezomib, which is currently being investigated in phase 3 trials as a treatment for multiple Myeloma. Despite the proven efficacy of these drugs in hematologic malignancies, clinical activity is limited to solid tumors such as colon adenocarcinoma. This study is the first to investigate and compare the antiproliferative and apoptotic effects of MLN2238 and bortezomib on human colon adenocarcinoma Caco2 cells. The antiproliferative effects of MLN2238 and bortezomib were determined using WST-1; apoptotic effects of this drug were determined by caspase-3 and a mitochondrial membrane potential (JC-1) activity assay. Expression levels associated with proteasome inhibition and apoptosis of NF-κB and c-myc mRNA were evaluated by RT-PCR. At 24 and 48 h, MLN2238 showed significant time- and concentration-dependent antiproliferative and apoptotic effects on Caco2 cells. Depending on increasing mitochondrial depolarization and caspase-3 activation, MLN2238 induced apoptosis at level similar to that of bortezomib. In addition, MLN2238 downregulated NF-κB and c-myc mRNA expression levels. For the first time, MLN2238 was shown to induce antiproliferative and apoptotic effects on human colon adenocarcinoma cells that are comparable with those of bortezomib; these in vitro data in Caco2 cells support the development of MLN2238 for colon cancer.

Abstract
Under physiological conditions, cells are in a stable state known as redox homeostasis, which is maintained by the balance between continuous ROS/RNS generation and several mechanisms involved in antioxidant activity. ROS overproduction results in alterations in the redox homeostasis that promote oxidative damage to major components of the cell, including the biomembrane phospholipids. Lipid peroxidation subsequently generates a diverse set of products, including α,β-unsaturated aldehydes. Of these products, 4-hydroxy-2-nonenal (HNE) is the most studied aldehyde on the basis of its involvement in cellular physiology and pathology. This review summarizes the current knowledge in the field of HNE generation, metabolism, and detoxification, as well as its interactions with various cellular macromolecules (protein, phospholipid, and nucleic acid). The formation of HNE-protein adducts enables HNE to participate in multi-step regulation of cellular metabolic pathways that include signaling and transcription of antioxidant enzymes, pro-inflammatory factors, and anti-apoptotic proteins. The most widely described roles for HNE in the signaling pathways are associated with its activation of kinases, as well as transcription factors that are responsible for redox homeostasis (Ref-1, Nrf2, p53, NFκB, and Hsf1). Depending on its level, HNE exerts harmful or protective effects associated with the induction of antioxidant defense mechanisms. These effects make HNE a key player in maintaining redox homeostasis, as well as producing imbalances in this system that participate in aging and the development of pathological conditions.

Differential Effects of Angelicin Analogues on NF- κB Activity and IL-8 Gene Expression in Cystic Fibrosis IB3-1 Cells. Mediators Inflamm 2017; 2017:2389487.

Abstract
The angelicin analogue 4,6,4′-trimethylangelicin (TMA) was recently reported as a strong inhibitor of nuclear factor-κB (NF-κB) activity and of the expression of the interleukin-8 (IL-8) gene in bronchial epithelial cells in which the inflammatory response has been challenged with P. aeruginosa, the most common bacterium found in the airways of patients affected by cystic fibrosis (CF). These findings encouraged us to analyze new synthetic analogues of TMA in order to evaluate their biological activities on human bronchial epithelial CF IB3-1 cells and to find more potent anti-NF-κB agents exhibiting only minor antiproliferative effects. Analogues able to inhibit NF-κB/DNA interaction at lower concentration than TMA were found and selected to investigate their biological activity on IB3-1 cells induced with TNF-α. In this biological system, NF-κB-mediated IL-8 gene expression was investigated. Some analogues showed similar activity to the lead compound TMA. Other analogues displayed higher activities; in particular, the most interesting compounds showing relevant anti-inflammatory effects were found to cause 56–83% reduction of IL-8 mRNA expression at low concentrations (1–10 μM), without changes in cell proliferation pattern, demonstrating their potential interest for a possible development of anti-inflammatory therapy of cystic fibrosis.

Abstract
Dieckol (DEK) is a major polyphenol of marine brown seaweed Ecklonia cava which is a potential candidate for cancer therapy. However, the underlying mechanism of DEK as an anticancer drug remains to be elucidated. In this study, we evaluated the molecular mechanisms involved in the chemopreventive efficacy of DEK in N-nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis rats by analyzing markers of xenobiotic-metabolizing enzymes (XMEs), apoptosis, invasion, and angiogenesis. Rats administered NDEA developed hepatocarcinogenesis that displayed apoptosis avoidance coupled to upregulation of pro-inflammatory, invasion, and angiogenesis markers. Treatment of DEK effectively suppressed the NDEA-initiated hepatocarcinogenesis by modulation of XMEs, inducing of apoptosis via the mitochondrial pathway as revealed by modulating the Bcl-2 family proteins, cytochrome C, caspases, and inhibiting invasion, and angiogenesis as evidenced by changes in the activities of MMPs (MMP2/9) and the expression of VEGF. In addition, DEK exerts its anticancer effects via inhibition of pro-inflammatory transcription factor NF-κB (nuclear factor κB) and COX2 in NDEA-induced hepatocarcinogenesis. Taken together, this study demonstrates that DEK modulates the expression of key molecules that regulate apoptosis, inflammation, invasion, and angiogenesis. These results strongly indicate that DEK from E. cava is an attractive candidate for chemoprevention.

Effect of natural and semi-synthetic cadinanes from Heterotheca inuloides on NF-κB, Nrf2 and STAT3 signaling pathways and evaluation of their in vitro cytotoxicity in human cancer cell lines. Bioorg Med Chem 2017; 25:3135-3147.

Abstract
The effects of ten natural cadinane sesquiterpenoids isolated from Heterotheca inuloides on the pathways of the NF-κB, Nrf2 and STAT3 transcription factors were studied for the first time. The main constituent in this species, 7-hydroxy-3,4-dihydrocadalene (1), showed anti-NF-κB activity and activated the antioxidant Nrf2 pathway, which may explain the properties reported for the traditional use of the plant. In addition to the main metabolite, a structurally similar compound, 7-hydroxy-cadalene (2), also displayed anti-NF-κB activity. Thus, both natural compounds were used as templates for the preparation of a novel semi-synthetic derivative set, including esters and carbamates, which were evaluated for their potential in vitro antiproliferative activities against six human cancer cell lines. Carbamate derivatives 32 and 33 were found to exhibit potent activity against human colorectal adenocarcinoma and showed important selectivity in cancer cells. Among ester derivatives, compound 13 was determined to be a more potent NF-κB inhibitor and Nrf2 activator than its parent, 7-hydroxy-3,4-dihydrocadalene (1). Furthermore, this compound decreases levels of phospho-IκBα, a protein complex involved in the NF-κB activation pathway. Molecular simulations suggest that all active compounds interact with the activation loop of the IKKβ subunit in the IKK complex, which is the responsible of IκBα phosphorylation. Thus, we identified two natural, and one semi-synthetic, NF-κB and Nrf2 modulators and two new promising cytotoxic compounds.

Abstract
Phosphatase and tensin homolog (PTEN) is a protein that regulates cellular response to growth/antigrowth signals, cell survival, apoptosis, proliferation, angiogenesis, and cellular migration. Impairments in these processes are the main hallmarks of cancer, and reduced expression, activity, or stability of PTEN are among the most common etiologies of diverse types of sporadic cancers. Rosiglitazone (RO), bortezomib (BO), phosphatidylserine (PH), ethanol (E), and radiotherapy (RA) (ROBOPHERA) stimulate the expression and increase the activity of PTEN. Here, it is hypothesized that the synergistic effects of these medications on cancerous cells may stimulate differentiation of cancer stem cells toward non-stem-cancer cells, hinder progression and metastasis of the cancer, sensitize cancerous cells to antineoplastic therapies, and increase the efficacy and the rate of success of current treatments.

Abstract
Hyperglycemia contributes to dysregulate endothelial function associated with diabetes, leading to initiation and propagation of vascular complications and dysfunction. Caffeic acid (CA), a dietary hydroxycinnamic acid abundant in coffee, has been reported to exert antidiabetic effects in rat models. Herein, we investigated the molecular effects of physiological concentrations of CA (10 nM) against endothelial dysfunction induced by high glucose (HG) in human endothelial cells (HUVECs). HUVECs were exposed to HG 25 mM, to mimic diabetic condition, in presence of CA. Intracellular redox status (reduced glutathione, superoxide dismutase (SOD) and total antioxidant activity levels), and NF-κB pathway were examined. We also evaluated the involvement of NF-E2-related factor 2 (Nrf2)/electrophile responsive element (EpRE) pathway. Our data show that CA inhibits HG-induced nuclear translocation of NF-κB and the downstream expression of endothelial adhesion molecule 1 and restores antioxidant levels by upregulating Nrf2/EpRE pathway. Our data suggest that CA can suppress several aspects of HG-induced endothelial dysfunction through the modulation of intracellular redox status controlled by the transcription factor Nrf2. These findings highlight that low physiological concentration of CA achievable specifically upon food consumption are able to prevent endothelial dysfunction associated with inflammation and oxidative stress induced by high concentration of glucose. © 2016 BioFactors, 43(1):54-62, 2017.

Abstract
Tumor necrosis factor alpha (TNF-α), originally described as an anti-neoplastic cytokine, has been found, in apparent contradiction to its name, to play an important role in promoting the development and progression of malignant disease. Targeting TNF-α with TNF antagonists has elicited an objective response in certain solid tumors in phase I and II clinical trials. This review focuses on the relationship of TNF-α expressed by leukemia cells and adverse clinical features of leukemia. TNF-α is involved in all steps of leukemogenesis, including cellular transformation, proliferation, angiogenesis, and extramedullary infiltration. TNF-α is also an important factor in the tumor microenvironment and assists leukemia cells in immune evasion, survival, and resistance to chemotherapy. TNF-α may be a potent target for leukemia therapy.

Abstract
CONTEXT Endophytic fungi, being a prolific source of bioactive secondary metabolites, are of great interest for natural product discovery. OBJECTIVE Isolation and partial characterization of endophytic fungi inhabiting the leaves and woody parts of Taxus fuana Nan Li & R.R. Mill. (Taxaceae) and evaluation of biological activity. MATERIALS AND METHODS Endophytic fungal isolates were identified by molecular analysis of internal transcribed spacer (ITS) regions of 18S rDNA. Extracts of the endophytic fungi cultured on potato dextrose agar and modified medium were evaluated using cancer chemoprevention bioassays [inhibition of TNF-α-induced NFκB, aromatase and inducible nitric oxide synthase (iNOS); induction of quinone reductase 1 (QR1)] and growth inhibition with MCF-7 cells. RESULTS Nine of 15 fungal isolates were identified as belonging to Epicoccum, Mucor, Penicillium, Chaetomium, Paraconiothriym, Plectania or Trichoderma. Five of the 15 extracts inhibited NFκB activity (IC50 values ranging between 0.18 and 17 μg/mL) and five inhibited iNOS (IC50 values ranging between 0.32 and 12.9 μg/mL). In the aromatase assay, only two isolates mediated inhibition (IC50 values 12.2 and 10.5 μg/mL). With QR1 induction, three extracts exhibited significant activity (concentrations to double activity values ranging between 0.20 and 5.5 μg/mL), and five extracts inhibited the growth of MCF-7 cells (IC50 values ranging from 0.56 to 17.5 μg/mL). Six active cultures were derived from woody parts of the plant material. CONCLUSION The endophytic fungi studied are capable of producing pharmacologically active natural compounds. In particular, isolates derived from the wood of Taxus fuana should be prioritized for the isolation and characterization of bioactive constituents.

Abstract
The preventive effect of a processed Aloe vera gel (PAG) on colon carcinogenesis was examined using an azoxymethane (AOM)-initiated and dextran sodium sulfate (DSS)-promoted mouse colon carcinogenesis model. Oral administration of PAG (200, or 400mg/kg/day) significantly reduced the multiplicity of colonic adenomas and adenocarcinomas compared with the AOM/DSS only-treated mice. In the mice treated with 400mg/kg of PAG, adenoma and adenocarcinoma development was reduced to 80% and 60%, respectively, compared to 100% in the PAG-untreated AOM/DSS-treated mice. Western blot analysis using colon extracts showed that PAG reduced the activation of nuclear factor kappa B (NF-κB), resulting in the inhibition of inducible nitric oxide synthase and cyclooxygenase-2 expression. PAG appeared to inhibit the NF-κB activation through the activation of peroxisome proliferator-activated receptor gamma. PAG also inhibited the expression and phosphorylation of signal transducer and activator of transcription 3, which is known to connect inflammation and cancer. In addition, PAG inhibited cell cycle progression-inducing cellular factors, such as extracellular signal-regulated kinases 1/2, cyclin-dependent kinase 4, and cyclin D1. On the other hand, PAG increased the expression of Caudal-related homeobox transcription factor 2, which is known to be a tumor suppressor in colorectal cancer. These findings show that PAG suppresses colitis-related colon carcinogenesis by inhibiting both chronic inflammation and cell cycle progression in the colon.

FISH & SHELLFISH IMMUNOLOGY 2016; 56:459-466. [PMID: 27492123 DOI: 10.1016/j.fsi.2016.07.038] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Revised: 07/13/2016] [Accepted: 07/31/2016] [Indexed: 06/06/2023]
Abstract
Pinocembrin is a flavonoid that has been reported to exhibit various pharmacological and biological activities including antimicrobial, antioxidant, and anti-inflammatory. To explore the anti-inflammatory activity of pinocembrin in a fish cell line, we investigated its ability to regulate the inflammatory mediators elevated by lipopolysaccharide (LPS) in Labeo rohita head-kidney (HK) macrophages. HK macrophages of L. rohita were treated with LPS (1 μg mL(-1)) in the presence or absence of pinocembrin. We examined the inhibitory effect of pinocembrin on LPS-induced nitric oxide (NO) and prostaglandin E2 (PGE2) production. The inhibitory effect of pinocembrin on nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) was investigated by RT-PCR and western blot. The effect of pinocembrin on pro-inflammatory cytokines (tumour necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β)) and anti-inflammatory cytokine IL-10 was investigated by ELISA and RT-PCR. The phosphorylation of three mitogen activated protein kinases (MAPKs) ERK, JNK, and p38 was analysed by western blot. Pinocembrin inhibited LPS-induced productions of NO and PGE2, and also markedly inhibited TNF-α, IL-1β, iNOS, and COX-2 production in a concentration-dependent manner. In addition, TNF-α and IL-1β mRNA expression levels decreased significantly, while IL-10 mRNA expression increased (P < 0.05) with pinocembrin pre-treatment. RT-PCR and western blot analysis showed that pinocembrin decreased both the mRNA and protein expression levels of LPS-induced iNOS and COX-2 in HK macrophages. Pinocembrin suppressed the phosphorylation of MAPK in LPS-stimulated HK macrophages. Further, pinocembrin significantly inhibited LPS-induced NF-κB transcriptional activity via the attenuation of IκBα degradation. Taken together, pinocembrin reduced the levels of pro-inflammatory mediators, such as iNOS, COX-2, TNF-α, and IL-1β, by inhibiting NF-κB activation via the suppression of ERK and p38 phosphorylation, and by attenuating the degradation of IκBα. These results suggest that pinocembrin is a potential novel candidate for the treatment of inflammatory conditions in L. rohita macrophages.

Evaluating ancient Egyptian prescriptions today: Anti-inflammatory activity of Ziziphus spina-christi. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2016; 23:293-306. [PMID: 26969383 DOI: 10.1016/j.phymed.2016.01.004] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2015] [Revised: 01/08/2016] [Accepted: 01/16/2016] [Indexed: 06/05/2023]
Abstract
BACKGROUND Ziziphus spina-christi (L.) Desf. (Christ's Thorn Jujube) is a wild tree today found in Jordan, Israel, Egypt, and some parts of Africa, which was already in use as a medicinal plant in Ancient Egypt. In ancient Egyptian prescriptions, it was used in remedies against swellings, pain, and heat, and thus should have anti-inflammatory effects. Nowadays, Z. spina-christi, is used in Egypt (by Bedouins, and Nubians), the Arabian Peninsula, Jordan, Iraq, and Morocco against a wide range of illnesses, most of them associated with inflammation. Pharmacological research undertaken to date suggests that it possesses anti-inflammatory, hypoglycemic, hypotensive and anti-microbial effects. The transcription factor NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) is critical in inflammation, proliferation and involved in various types of cancer. Identification of new anti-inflammatory compounds might be an effective strategy to target inflammatory disorders and cancer. Therefore, extracts from Z. spina-christi are investigated in terms of their anti-inflammatory effects. Our intention is to evaluate the effects of Z. spina-christi described in ancient Egyptian papyri, and to show whether the effects can be proven with modern pharmacological methods. Furthermore, we determine the active ingredients in crude extracts for their inhibitory activity toward NF-κB pathway. MATERIALS AND METHODS To determine the active ingredients of Z. spina-christi, we fractionated the extracts for bioassays and identified the active compounds. Epigallocatechin, gallocatechin, spinosin, 6''' feruloylspinosin and 6''' sinapoylspinosin and crude extracts of seed, leaf, root or stem were analyzed for their effect on NF-κB DNA binding by electromobility shift assay (EMSA) and nuclear translocation of NF-κB-p65 by Western blot analysis. The binding mode of the compounds to NF-κB pathway proteins was compared with the known inhibitor, MG-132, by in silico molecular docking calculations. Log10IC50 values of gallocatechin and epigallocatechin as two main compounds of the plant were correlated to the microarray-based mRNA expression of 79 inflammation-related genes in cell lines of the National Cancer Institute (NCI, USA) as determined. The expression of 17 genes significantly correlated to the log10IC50 values for gallocatechin or epigallocatechin. RESULTS Nuclear p65 protein level decreased upon treatment with each extract and compound. Root and seed extracts inhibited NF-κB-DNA binding as shown by EMSA. The compounds showed comparable binding energies and similar docking poses as MG-132 on the target proteins. CONCLUSION Z. spina-christi might possess anti-inflammatory activity as assumed by ancient Egyptian prescriptions. Five compounds contributed to this bioactivity, i.e. epigallocatechin, gallocatechin, spinosin, 6''' feruloylspinosin and 6''' sinapoylspinosin as shown in vitro and in silico.
