This study aimed to investigate the protective effect of melatonin on corneal epithelium in dry eye disease(DED) and explore its underlying mechanism. Human epithelial(HCE) cells was exposure t-butylhydroperoxide(tBH), C57BL/6 mice were injected subcutaneous scopolamine imitate DED. Melatonin used both vivo vitro. Cell viability detected by Counting Kit-8 assay Lactate Dehydrogenase Leakage. The change cellular reactive oxygen species (ROS) levels, mitochondrial membrane potential (MMP), apoptosis analyzed flow cytometry. Western blot assays immunofluorescence carried out measure protein changes. mRNA expression investigated RNA sequencing (RNA-Seq) quantitative real-time PCR. autophagic flux observed through mCherry-GFP-LC3 transfection electron microscopy(TEM). Clinical parameters defects, conjunctival goblet cells, tear volume, level ocular surface inflammation recorded. able reduce excessive ROS production maintain function. TEM found rescued impaired under tBH. Moreover, significantly preserved cell viability, abolished LDH release, decreased apoptosis. RNA-Seq indicated that greatly activating hemeoxygenase-1 (HO-1) expression. Interestingly, HO-1 ablation largely attenuated effects. Besides, mouse model, intraperitoneal injection showed improved clinical parameters, inhibited activated NLRP3 cascade, increased density volume. Thus, protects epithelial from oxidative damage, normal autophagy, via trigging

Rationale: Colorectal cancer (CRC) is a common malignant tumor of the digestive system. However, efficacy surgery and chemotherapy limited. Ferroptosis an iron- reactive oxygen species (ROS)-dependent form regulated cell death (RCD) plays vital role in suppression. inducing agents have been studied extensively as novel promising way to fight against therapy resistant cancers. The aim this study investigate mechanism action tagitinin C (TC), natural product, ferroptosis inducer Methods: response CRC cells was assessed by viability assay, clonogenic transwell migration cycle assay apoptosis assay. Molecular approaches including Western blot, RNA sequencing, quantitative real-time PCR immunofluorescence were employed well. Results: Tagitinin C, sesquiterpene lactone isolated from Tithonia diversifolia, inhibits growth colorectal HCT116 cells, induced oxidative cellular microenvironment resulting cells. C-induced accompanied with attenuation glutathione (GSH) levels increased lipid peroxidation. Mechanistically, endoplasmic reticulum (ER) stress stress, thus activating nuclear translocation factor erythroid 2-related 2 (Nrf2). As downstream gene (effector) Nrf2, heme oxygenase-1 (HO-1) expression significantly treatment C. Upregulated HO-1 led increase labile iron pool, which promoted peroxidation, meanwhile showed synergistic anti-tumor effect together erastin. Conclusion: In summary, we provided evidence that induces has through ER stress-mediated activation PERK-Nrf2-HO-1 signaling pathway. identified inducer, may be effective chemosensitizer can expand range chemotherapeutic agents.

In recent years, the incidence of gastrointestinal cancers is increasing, particularly in younger population. Effective treatment crucial for improving patients' survival outcomes. Programmed cell death, regulated by various genes, plays a fundamental role growth and development organisms. It also critical maintaining tissue organ homeostasis takes part multiple pathological processes. addition to apoptosis, there are other types programmed such as ferroptosis, necroptosis, pyroptosis, which can induce severe inflammatory responses. Notably, besides pyroptosis contribute occurrence cancers. This review aims provide comprehensive summary on biological roles molecular mechanisms well their regulators hope open up new paths tumor targeted therapy near future.

Oral squamous cell carcinoma (OSCC) is the leading cause of mortality for oral cancer. Numerous risk factors mainly related to unhealthy habits and responsible chronic inflammation infections have been recognized as predisposing carcinogenesis. Recently, even microbiota alterations associated with development human cancers. In particular, some specific bacterial strains strongly cancer (Capnocytophaga gingivalis, Fusobacterium spp., Streptococcus Peptostreptococcus Porphyromonas gingivalis Prevotella spp.). Several hypotheses proposed explain how could be involved in pathogenesis by paying attention inflammation, microbial synthesis cancerogenic substances, alteration epithelial barrier integrity. Based on knowledge carcinogenic effects dysbiosis, it was recently suggested that probiotics may anti-tumoral activity. Nevertheless, few data exist regard probiotic On this basis, association between dysbiosis discussed focusing potential benefits administration prevention.

In this study, the anti-ferroptosis effects of catecholic flavonol quercetin and its metabolite Diels-Alder anti-dimer (QDAD) were studied using an erastin-treated bone marrow-derived mesenchymal stem cell (bmMSCs) model. Quercetin exhibited higher levels than QDAD, as indicated by 4,4-difluoro-5-(4-phenyl-1,3-butadienyl)-4-bora-3a,4a-diaza-s-indacene-3-undecanoic acid (C11-BODIPY), 2′,7′-dichlorodihydrofluoroscein diacetate (H2DCFDA), lactate dehydrogenase (LDH) release, counting kit-8 (CCK-8), flow cytometric assays. To understand possible pathways involved, reaction product with 1,1-diphenyl-2-picrylhydrazyl radical (DPPH●) was measured ultra-performance liquid-chromatography coupled electrospray-ionization quadrupole time-of-flight tandem mass spectrometry (UHPLC-ESI-Q-TOF-MS). found to produce same clusters molecular ion peaks fragments standard QDAD. Furthermore, antioxidant QDAD compared determining their 2-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide radical-scavenging, Cu2+-reducing, Fe3+-reducing, lipid peroxidation-scavenging, DPPH●-scavenging activities. consistently showed lower IC50 values These findings indicate that can protect bmMSCs from erastin-induced ferroptosis, possibly through pathway. The pathway convert into QDAD—an inferior ferroptosis-inhibitor antioxidant. weakening has highlighted a rule for predicting relative flavonols dimer metabolites.
