Key result

Co-stimulation of human mesangial cells with thrombin and TNFalpha synergistically upregulated preproET-1 gene expression via p38 MAPK and PKC pathways, overcoming negative promoter modulation.

Population

Human mesangial cells

Comparison

Co-stimulation with thrombin and tumor necrosis… vs Thrombin alone or unstimulated cells

Implication

May inform ET-1 regulation in inflammatory renal disease; hypothesis-generating and requires in vivo confirmation before any clinical consideration.

Co-stimulation with thrombin and TNFalpha synergistically upregulates preproET-1 expression in human mesangial cells via p38 MAPK and PKC pathways, suggesting a mechanism for ET-1 production in inflammatory renal disease.

Foschi et al. (2001) studied Renal inflammation. Thrombin and TNFalpha co-stimulation vs. Thrombin alone was evaluated on preproET-1 gene expression. Co-stimulation of human mesangial cells with thrombin and TNFalpha synergistically upregulated preproET-1 gene expression via p38 MAPK and PKC pathways, overcoming negative promoter modulation.
