Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications
Portal Hypertension &Cirrhosis, EarlyView.This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

, 2008 Activin A is a well characterised inhibitor of proliferation in most epithelial cells. The actions of activin A on cell growth are mediated through Smad-dependent pathways. Activin A is potent at low levels, therefore its synthesis and bioactivity must

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Background Immunotherapy response rates in head and neck squamous cell carcinoma (HNSCC) are limited by multiple factors. Tumor cell‐derived follistatin (FST) has been linked to immunotherapy resistance, but the underlying mechanisms remain poorly understood. This study aimed to investigate the prognostic value of FST and its associations with

Cancers, 2014 In recent years, a significant amount of research has examined the controversial role of activin A in cancer. Activin A, a member of the transforming growth factor β (TGFβ) superfamily, is best characterized for its function during embryogenesis in ...

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche
Insect Science, EarlyView.Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

PLoS ONE, 2019 Activin A, a member of the transforming growth factor-beta superfamily, is a critical modulator of inflammation and plays a key role in controlling the cytokine cascade that drives the inflammatory response. However, the role of activin A in inflammatory

Integrative Zoology, EarlyView.① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

Allergy, EarlyView.Gene expression of Ara h 2‐specific B cells over the course of the peanut OIT. Isotype of allergen‐specific B cells changes through OIT towards IgG4. Peanut OIT changes the gene expression of allergen‐specific memory B cells. OIT patients showed increased gene expression for regulatory B cells and immune regulation.
