1 Retinoic acid improves nephrotoxic serum-induced glomerulonephritis through activation of podocyte retinoic acid receptor alpha. Tretinoin retinoic acid receptor, alpha Mus musculus
2 We previously found that retinoic acid (RA) inhibits proliferation and induces differentiation of podocytes by activating RA receptor-alpha (RARalpha) in a murine model of HIV-associated nephropathy. Tretinoin retinoic acid receptor, alpha Mus musculus
3 We previously found that retinoic acid (RA) inhibits proliferation and induces differentiation of podocytes by activating RA receptor-alpha (RARalpha) in a murine model of HIV-associated nephropathy. Tretinoin retinoic acid receptor, alpha Mus musculus
4 RA treatment markedly improved renal function and reduced the number of crescentic lesions in nephritic wild-type mice, while this protection was largely lost in mice with podocyte-specific ablation of Rara (Pod-Rara knockout). Tretinoin retinoic acid receptor, alpha Mus musculus
5 RA treatment markedly improved renal function and reduced the number of crescentic lesions in nephritic wild-type mice, while this protection was largely lost in mice with podocyte-specific ablation of Rara (Pod-Rara knockout). Tretinoin retinoic acid receptor, alpha Mus musculus
6 Furthermore, RA suppressed the expression of cell injury, proliferation, and parietal epithelial cell markers in nephritic wild-type mice, all of which were significantly dampened in nephritic Pod-Rara knockout mice. Tretinoin retinoic acid receptor, alpha Mus musculus
7 Thus, RA attenuates crescentic glomerulonephritis primarily through RARalpha-mediated protection of podocytes and in part through the inhibition of parietal epithelial cell proliferation and induction of their transdifferentiation into podocytes. Tretinoin retinoic acid receptor, alpha Mus musculus
