Background It is well established that females are more susceptible to the toxic effects of alcohol, although exact mechanisms still poorly understood. Previous studies noted alcohol reduces expression mitogen-activated protein kinase phosphatase 1 (MKP1), a negative regulator kinases (MAPK) in liver. However, role hepatocyte- specific MKP1 pathogenesis alcohol-associated liver disease (ALD) remains uncharacterized. This study aimed evaluate hepatocyte-specific susceptibility and sexual dimorphism alcohol-induced injury. Methods C57Bl/6 mice were used an intragastric ethanol feeding model steatohepatitis (ASH). Hepatocyte-specific Mkp1 -/- knockout ( +/+ “f/f” male female subjected NIAAA chronic plus binge model. Primary mouse hepatocytes for vitro studies.

BACKGROUND Liver hepatocellular carcinoma (LIHC) is a highly aggressive cancer with poor prognosis due to its complex tumor microenvironment (TME) and immune evasion. Regulatory T cells (Tregs) play critical role in progression. Suppressor of cytokine signaling 2 (SOCS2), key regulator, may modulate Treg activity impact LIHC growth metastasis. AIM To explore how the SOCS2 affects on METHODS transcriptome data from The Cancer Genome Atlas database were analyzed using Gene Set Enrichment Analysis, Estimation Stromal Immune Cells Malignant Tumors Using Expression Data, Cell-Type Identification by Estimating Relative Subsets RNA Transcripts evaluate pathways infiltration. Key prognostic genes identified Weighted Co-expression Network Analysis machine learning. In vitro , co-culture experiments, migration assays, apoptosis detection, enzyme-linked immunosorbent assay conducted. vivo growth, metastasis, assessed subcutaneous lung metastasis mouse models hematoxylin eosin staining, Terminal Deoxynucleotidyl Transferase dUTP Nick End Labeling, immunohistochemistry analyses. RESULTS overexpression inhibited cell activity, reducing invasion while increasing apoptosis. suppressed confirming therapeutic potential. CONCLUSION modulates CD4+ function TME, contributing Targeting presents potential strategy for treating LIHC.

Background: Hepatocellular carcinoma (HCC) is a prevalent and highly lethal form of liver cancer, with limited effective treatment options, particularly in the advanced stages. Immunotherapy using PD-1 inhibitors has emerged as promising modality, yet substantial proportion patients exhibit resistance or fail to respond such therapies. This study aimed elucidate role G0/G1 Switch 2 (G0S2) regulating PD-L1 expression monocytes within HCC tumor microenvironment investigate its impact on efficacy inhibitors. Methods: Gene data among treated were obtained from single-cell sequencing database; immunohistochemistry was performed detect G0S2 cancer tissues adjacent non-tumorous patients; flow cytometry utilized analyze G0S2, PD-L1, CD206, CD14 PBMCs CD8+T cell proliferation IFN-γ secretion used evaluate knockdown. Results: Utilizing patients, we identified that significantly elevated non-responders (NR) compared responders (R) inhibitor therapy. The immunohistochemical analysis confirmed higher levels tissues, while revealed increased CD206 peripheral blood mononuclear cells (PBMCs) NR R healthy controls. functional experiments involving knockdown THP-1 monocyte line resulted significant reduction concomitant increase production. Conclusions: These findings indicate facilitates upregulation monocytes, thereby suppressing T activity contributing against HCC. high offers non-invasive easily detectable biomarker for predicting Consequently, targeting may enhance responsiveness immunotherapy providing new avenue optimizing strategies improving patient outcomes.

Introduction The four members of the p90 ribosomal S6 kinase (RSK) family are serine/threonine protein kinases, which phosphorylated and activated by ERK1/2. RSK1/2/3 further PDK1. Receiving inputs from two major signaling pathways places RSK as a key node in numerous pathologies. A plethora RSK1/2 substrates have been identified, majority cases causative roles these play pathology unknown.

While steroid therapy is the preferred treatment for severe alcohol-associated hepatitis, role of effector regulatory T (eTreg) cells and their association with response clinical outcomes in these patients remains to be elucidated. We prospectively enrolled 47 consecutive consisting hepatitis treated steroids (n=18; steroid-treated group) mild (n=29; nontreated group). After isolating peripheral blood mononuclear from at enrollment again 7 days later, frequency eTreg was examined using flow cytometry. Single-cell RNA sequencing analysis conducted paired cells. In vitro experiments were also performed assess phenotype changes suppressive function Treg following treatment. The group exhibited significantly higher Model End-Stage Liver Disease scores than ( p < 0.01). Within group, proportion expanded responders (n=13; = Furthermore, a significant positive correlation observed between decrease score increase 0.05). (pre-steroid post-steroid therapy) responder revealed gene expression monocytes, suggesting enhancement cell function. results showed an elevation after therapy. conclusion, our findings suggest that efficacy mediated by number
