Zhilining formula alleviates ulcerative colitis by restricting STAT3 activation and subsequent Th17 cell differentiation.

Phytomedicine : international journal of phytotherapy and phytopharmacology
BACKGROUND: Ulcerative colitis (UC) is a chronic, relapsing inflammatory bowel disease with rising prevalence and limited therapies. Zhilining Formula (ZLN), a Traditional Chinese Medicine (TCM), shows clinical efficacy in UC, yet its core material b...

SLC25A39 regulates Hedgehog signaling to promote tumor progression and sorafenib resistance in hepatocellular carcinoma.

Scientific reports
Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC), yet resistance limits its efficacy. The Hedgehog (HH) signaling pathway contributes to drug resistance by maintaining HCC stem cell characteristics, but its role at the ...

Mechanistic Basis for GPCR Phosphorylation-Dependent Allosteric Signaling Specificity of β-Arrestin 1 and 2.

Journal of chemical information and modeling
β-Arrestins (βarr1 and βarr2) are key transducers of G protein-coupled receptor (GPCR) signaling, orchestrating both shared and isoform-specific intracellular pathways. Phosphorylation of the receptor C-terminal tail by GPCR kinases encodes regulator...

Tanshinone IIA ameliorates pancreatic injury in type 2 diabetic mice by modulating inflammation and endoplasmic reticulum stress via the IL-6/JAK2/STAT3 pathway.

Functional & integrative genomics
Type 2 diabetes mellitus (T2DM) is a severe metabolic disorder in which pancreatic injury plays a pivotal role in disease progression. Tanshinone IIA (TanIIA), a bioactive compound extracted from Salvia miltiorrhiza, has shown therapeutic potential i...

Artesunate alleviates chronic allergic rhinitis and asthma syndrome via the CCR3/NF-κB pathway: a comprehensive analysis.

International immunopharmacology
BACKGROUND: Chronic allergic rhinitis and asthma syndrome (CARAS) is a comorbid inflammatory condition affecting both upper and lower airways, with limited treatment options. Artesunate (ART), a derivative of artemisinin, has shown anti-inflammatory ...

SPP1 as a key modulator of M2 macrophage polarization promotes endometriosis progression via activation of the FAK/PI3K/AKT pathway: A bioinformatics and experimental study.

International immunopharmacology
Endometriosis (EMs) is a gynecological disorder characterized by chronic inflammation and an aberrant immune microenvironment. In this study, we integrated the GSE6364 dataset from the GEO database to identify differentially expressed genes, and appl...

Neural xenografts contribute to long-term recovery in stroke via molecular graft-host crosstalk.

Nature communications
Stroke remains a leading cause of disability due to the brain's limited ability to regenerate damaged neural circuits. Here, we show that local transplantation of iPSC-derived neural progenitor cells (NPCs) improves brain repair and long-term functio...

Bone marrow immune remodeling in depression: TNF/NF-κB mediated leukocyte redistribution and construction of an interpretable predictive model.

International immunopharmacology
Environmental stress contributes to the development of depression through neuro-immune interactions, yet the underlying molecular mechanisms and associated clinical diagnostic biomarkers remain unclear. We established a psychosocial stress mouse mode...

Screening of hub genes and immunocytes related to tendon injury based on bioinformatics and machine learning models.

Scientific reports
Tendon injury is a common and challenging clinical problem, and its healing process involves complex cellular and biological factors. Therefore, this study aims to reveal the mechanism of tendon healing and provide theoretical basis for clinical trea...
