Oxidative stress and inflammation are mediated via aryl hydrocarbon receptor signalling in idiopathic membranous nephropathy
Free Radic Biol Med. 2023 Jul 12:S0891-5849(23)00543-9. doi: 10.1016/j.freeradbiomed.2023.07.014. Online ahead of print.ABSTRACTMembranous nephropathy (MN) patients are diagnosed by the presence of phospholipase A2 receptor (PLA2R) before they progress to renal failure. However, the subepithelium-like immunocomplex deposit-mediated downstream molecular pathways are poorly understood. The aryl hydrocarbon receptor (AHR), NF-ƙB and Nrf2 pathways play central roles in the pathogenesis and progression of chronic kidney disease. However, their mutual effects on MN require further examination. Thus, we investigated the effect o...

Extracellular matrix-induced Hic-5 expression in glomerular mesangial cells leads to a prosclerotic phenotype independent of TGF-{beta} Research Communication
Chronic fibroproliferative diseases account for approximately 45% of all deaths in the developed world. In the kidney, glomerulosclerosis is the underlying pathology in approximately half of patients with renal failure receiving dialysis. Mesangial cell expression of the LIM protein hydrogen peroxide-induced clone-5 (Hic-5) is important in its pathogenesis. Hic-5 expression increases following mesangial cell attachment to collagen I, associated with increased collagen I expression and increased susceptibility to apoptosis both in vitro and in experimental glomerulosclerosis. TGF-β has an established role in many fibro...
