CASP3 and diabetic kidney disease: Experimentally, AS significantly suppressed expression of ECM-related proteins (Col-IV, LN, IL-6, IL-17) and pro-apoptotic proteins (Bax, Caspase-3), while restoring anti-apoptotic Bcl-2 levels and inhibiting phosphorylation of MEK4, JNK1, c-Jun, and FOS in DKD mice.
