Abstract The liver carries out many essential tasks, such as synthesising cholesterol, controlling the body’s storage of glycogen, and detoxifying metabolites, in addition to performing, regulating homeostasis. Hepatic fibrosis is a pathological state characterized by over accumulation extracellular matrix (ECM) including collagen fibers. Sildenafil (a selective inhibitor type 5 phosphodiesterase) has anti-inflammatory, antioxidant anti-apoptotic properties. It commonly used treat erectile dysfunction male. purpose current investigation was evaluate sildenafil’s hepatoprotective potential against rats that caused carbon tetrachloride (CCl 4 ). Liver enzymes oxidative markers well profibrotic genes were determined. findings showed sildenafil alleviates hepatic dysfunctions CCl restoring normal levels ALT, AST, GGT status demonstrated increased glutathione (GSH), catalase. In addition, significantly down-regulated mRNA expressions [collagen-1α, IL-1β, osteopontin (OPN), transforming growth factor-β (TGF-β)]. Additionally, lessens periportal between lobules, congestion dilatation central vein, inflammatory cell infiltrations. As result, it hypothesized may be helpful management hepatotoxicity brought on through suppressing OPN.

Selenoprotein GPX4 (glutathione peroxidase 4), originally known as PHGPX (phospholipid hydroperoxide glutathione peroxidase), is the main oxidoreductase in use of a reducing agent scavenging lipid peroxidation products. There are three isoforms: cytosolic (cGPX4), mitochondrial (mGPX4), and nuclear (nGPX4), with distinct spatiotemporal expression patterns during embryonic development adult life. In addition to inducing phenotype ferroptosis, loss can some cells trigger apoptosis, necroptosis, pyroptosis, or parthanatos, which mediates accelerates developmental defects, tissue damage, sterile inflammation. The interaction autophagic degradation pathway further modulates cell fate response oxidative stress. Impaired function implicated tumorigenesis, neurodegeneration, infertility, inflammation, immune disorders, ischemia-reperfusion injury. Additionally, R152H mutation promote Sedaghatian-type spinal metaphyseal dysplasia, rare fatal disease newborns. Here, we discuss roles classical functions well emerging GPX4-regulated processes death, autophagy, disease.Abbreviations: AA: arachidonic acid; cGPX4: GPX4; CMA: chaperone-mediated autophagy; DAMPs: danger/damage-associated molecular patterns; mGPX4: nGPX4: GSDMD-N: N-terminal fragment GSDMD; I/R: ischemia-reperfusion; PLOOH: phospholipid hydroperoxide; PUFAs: polyunsaturated fatty acids; RCD: regulated death; ROS: reactive oxygen species; Se: selenium; SSMD: spondylometaphyseal dysplasia; UPS: ubiquitin-proteasome system

Abstract Ferroptosis, a unique modality of cell death with mechanistic and morphological differences from other modes, plays pivotal role in regulating tumorigenesis offers new opportunity for modulating anticancer drug resistance. Aberrant epigenetic modifications posttranslational (PTMs) promote resistance, cancer progression, metastasis. Accumulating studies indicate that can transcriptionally translationally determine vulnerability to ferroptosis functions as driver nervous system diseases (NSDs), cardiovascular (CVDs), liver diseases, lung kidney diseases. In this review, we first summarize the core molecular mechanisms ferroptosis. Then, roles processes, including histone PTMs, DNA methylation, noncoding RNA regulation such phosphorylation, ubiquitination, SUMOylation, acetylation, ADP-ribosylation, are concisely discussed. The PTMs genesis cancers, NSD, CVDs, well application PTM modulators therapy these then discussed detail. Elucidating mediated by will facilitate development promising combination therapeutic regimens containing or PTM-targeting agents inducers be used overcome chemotherapeutic resistance could prevent addition, highlight potential approaches chemoresistance halt

Alzheimer's disease (AD) is a neurogenerative and remains no effective method for stopping its progress. Ferroptosis adaptive immunity have been proven to contribute AD pathogenesis. Salidroside exhibits neuroprotective immunomodulatory effects. However, the underlying mechanisms linking salidroside, ferroptosis, in remain uncertain.The objective of this study explore effects potential molecular salidroside against neuronal ferroptosis CD8+ T cell infiltration senescence-accelerated mouse prone 8 (SAMP8) mice.SAMP8 mice were employed as an model treated with 12 weeks. Behavioral tests, immunohistochemistry, HE Nissl staining, immunofluorescence, transmission electron microscopy, quantitative proteomics, bioinformatic analysis, flow cytometry, iron western blotting, docking performed.Treatment dose-dependently attenuated cognitive impairment, reduced accumulation Aβ plaques restored damage. also suppressed CD8+T cells, oxidative stress, inflammatory cytokines, improved mitochondrial metabolism, lipid redox SAMP8 brain. The administration decreased deposition, TFR1, ACSL4 protein expression, upregulated SLC7A11, GPX4 promoted Nrf2/GPX4 axis activation.In conclusion, cells are involved process impairment mice. alleviates inhibits ferroptosis. may involve activation reduction infiltration. This provides some evidence roles

The endoplasmic reticulum (ER) played an important role in the folding, assembly and post-translational modification of proteins. ER homeostasis could be disrupted by accumulation misfolded proteins, elevated reactive oxygen species (ROS) levels, abnormal Ca2+ signaling, which was referred to stress (ERS). Ferroptosis a unique programmed cell death model mediated iron-dependent phospholipid peroxidation multiple signaling pathways. changes mitochondrial structure, damage glutathione peroxidase 4 (GPX4) excess iron were main characteristics ferroptosis. ROS produced ferroptosis can interfere with activity protein-folding enzymes, leading large amounts unfolded thus causing ERS. On contrary, increase ERS level promote ion lipid peroxide, up-regulation related genes. At present, studies on relationship between one-sided lack in-depth interaction mechanism. This review aimed explore molecular mechanism cross-talk ERS, provide new strategies targets for treatment liver diseases.
