• Nicotine Signaling in Chronic Kidney Disease Progression

  2026-08-30

  Jain and Jaimes integrate clinical and experimental evidence showing that nicotine may directly accelerate chronic kidney disease through non-neuronal nicotinic acetylcholine receptors, oxidative stress, hemodynamic changes, and pro-fibrotic signaling. The review’s main practical contribution is a mechanistic framework for connecting smoking exposure with renal injury across diabetes, hypertension, transplantation, and other CKD settings.

• HOXB4, BMSCs, and Wnt Signaling in Acute Lung Injury

  2026-08-29

  Lin et al. show that HOXB4-overexpressing bone marrow mesenchymal stem cells protect lipopolysaccharide-injured endothelial cells more effectively than unmodified BMSCs. Their transwell coculture and XAV-939 inhibition experiments connect this benefit partly to restoration of Wnt/β-catenin signaling, while also highlighting the need for in vivo validation.
