MRSA Extracellular Vesicles Drive OSCC via IL-8
2026-09-12
This study identifies methicillin-resistant Staphylococcus aureus extracellular vesicles as active drivers of oral squamous cell carcinoma progression, rather than passive by-products of infection. Its experiments connect EV uptake with ERK/c-Jun activation, increased IL-8 signaling through CXCR1, and downstream JAK/STAT5A activity, providing a mechanistic framework for studying antibiotic-resistant bacteria in the tumor microenvironment.

Anp32e Drives Renal Fibrosis Through TGF-β/Smad3
2026-09-11
The reference study identifies Anp32e as a previously underappreciated promoter of renal interstitial fibrosis and links its activity to activation of the TGF-β1/Smad3 axis. Evidence from IgA nephropathy tissue, unilateral ureteral obstruction mice, and proximal tubular cells suggests that Anp32e may participate in a feed-forward pathway that increases fibronectin and collagen I deposition.
