体外研究 (In Vitro) | Vps34-PIK-III (1, 5, 10 μM; 24 h) inhibits autophagy and LC3 lipidation in DLD1 cells[1]. Vps34-PIK-III (1, 5, 10 μM; 24 h) leads to an increase in the lipidated and nonlipidated forms of LC3 in DLD1 cells[1]. Vps34-PIK-III (5 μM; 24 h) significantly decreases the expression of stemness genes in HCC cells[2]. Vps34-PIK-III (5 μM; 24 h) suppresses liver CSCs via AMPK activation in Huh7 and MHCC97H cells[2].
