Prevention of Fibrosis and Pathological Cardiac Remodeling by Salinomycin

Scientists demonstrated that salinomycin displayed potent anti-fibrotic activity in cardiac fibroblasts obtained from heart failure patients. In pre-clinical studies, salinomycin prevented cardiac fibrosis and functional decline in mouse models of ischemic and non-ischemic heart disease.

Complement Factor I Upregulates Expression of Matrix Metalloproteinase‐13 and ‐2 and Promotes Invasion of Cutaneous Squamous Carcinoma Cells

The authors studied the functional role of complement factor I (CFI) in the progression of cutaneous squamous cell carcinoma (cSCC). CFI was knocked down in cSCC cells and RNA‐seq analysis was performed.
