Matrine exerts an anti?tumor effect via regulating HN1 in triple breast cancer both in vitro and in vivo

Chemical Biology and Drug Design

Matrine inhibits TNBC cell proliferation, migration and invasion, promotes apoptosis, and suppresses tumor growth through down-regulation of HN1 expression. This study aimed to investigate the anti-tumor effect of matrine on the proliferation and apoptosis of TNBC cells based on HN1 regulation in vitro and in vivo.

Icariin promotes osteogenic differentiation of human bone marrow mesenchymal stem cells by regulating USP47/SIRT1/Wnt/??catenin

Chemical Biology and Drug Design

However, the underlying molecular mechanism by which Icariin regulates osteogenic differentiation needs to be further revealed. The protein levels of osteogenic differentiation-related markers, sirtuin 1 (SIRT1), ubiquitin-specific protease 47 (USP47), and Wnt/β-catenin-related markers were determined using western blot.

Hsa?miR?503?5p regulates CTDSPL to accelerate cisplatin resistance and angiogenesis of lung adenocarcinoma cells

Chemical Biology and Drug Design

High expression of hsa-miR-503-5p and decreased expression of CTDSPL in LUAD contribute to cisplatin resistance and angiogenesis. Hsa-miR-503-5p negatively regulates CTDSPL, suggesting its potential as a target to overcome cisplatin resistance in LUAD.

Jasminoidin reduces ischemic stroke injury by regulating microglia polarization via PASK?EEF1A1 axis

Chemical Biology and Drug Design

The mRNA or protein expressions of examined genes in microglia and brain tissues were detected by quantitative real-time polymerase chain reaction or western blot. JAS reduces IS injury by regulating microglia polarization via PASK-EEF1A1 axis. PASK overexpression reversed the effects of JAS on microglia.

Curcumin activates the JNK signaling pathway to promote ferroptosis in colon cancer cells

Chemical Biology and Drug Design

Curcumin modulates the gene and protein expression levels of ferroptosis mediators via JNK signaling. Ferroptosis, a new form of regulated cell death, plays a vital role in the pathogenesis and therapy of cancers.

Prostaglandin E2 may clinically alleviate dry eye disease by inducing Th17 cell differentiation

Chemical Biology and Drug Design

This study aimed to explore the mechanism through which prostaglandin E2 (PGE2) affects DE inflammation by regulating Th17. RT-qPCR and western blotting were used to test the mRNA and protein expression levels of IL-17 and retinoid-related orphan receptor-γt (RORγt). PGE2 was highly expressed in the DE mouse model.
