WebApr 2, 2024 · For instance, calpain induction by tumor necrosis factor-α can be reversed by p38-mitgen-activated protein kinase inhibitor SB203580 [ 28 ]; thus, the induction may be mediated through the p38 transcriptional systems. Other researchers documented that treatment of hepatocytes with CCl 4 upregulates Capn2 mRNA expression [ 29 ].
