Nitric oxide (NO) plays an important role in the progression of early-stage diabetic nephropathy (DN), which is found to contribute to extracellular matrix (ECM) accumulation in mesangial cells (MCs). As a cofactor for NO production, tetrahydrobiopterin (BH4), a folacin analogue, may be responsible for the ECM accumulation and proliferation of MCs. This study was to investigate the effects of BH4 on glomerulosclerosis in early-stage DN.
