LIMD1 and lung adenocarcinoma: LIMD1 overexpression increased the sensitivity of lung adenocarcinoma cells to cisplatin, but after the p38 MAPK signaling pathway was inhibited by SB203580, the expression of proapoptotic proteins in the LIMD1-overexpressing group was significantly decreased, suggesting that inhibiting the p38 MAPK signaling pathway can reverse the increase in apoptotic protein expression induced by LIMD1 overexpression.
