BMP2 and focal segmental glomerulosclerosis: Subsequently, a network pharmacology-based approach was used to identify the potential targets of the YSHS granule for the alleviation of glomerulosclerosis in FSGS, and the results showed that the YSHS granule down-regulated the expressions of BMP2, GSTA1, GATS3, BST1, and S100A9 and up-regulated the expressions of TTR and GATM in ADR-induced FSGS model mice.
