title: The Interplay between Autophagy and Apoptosis Induced by One Synthetic Curcumin Derivative Hydrazinobenzoylcurcumin in A549 Lung Cancer Cells.
abstract: The two important cell autonomic responses, autophagy, and apoptosis, play critical roles in cellular homeostasis and survival. By studying of the synthetic curcumin derivative hydrazinobenzoylcurcumin (HBC), we revealed that it could induce autophagy in nonsmall lung cancer cells (A549). Here, we use the Hoechst 33342 staining, Annexin V/propyliodide double dyeing and Western blotting analysis of PARP protein to demonstrate that HBC could also induce apoptosis in A549 cells. Apoptosis inhibitor (Z-VAD-FMK, 10 μM) treatment helps to promote the cells survival. Moreover, inhibition of apoptosis-promoted HBC-induced autophagy of A549 cells by morphological detection and Western blotting analysis (vice versa). These data indicate that there exist some interconnections between the autophagy and apoptosis induced by HBC. The following work will be carried out to characterize the specific regulation processes between the two cell pathways in A549 cells.
