RESUMO
Toxicity and autophagy effects of a new complex of platinum II (CPC) were evaluated on HeLa cells cultured on a PCL/gelatin electrospinning scaffold. HeLa cells were treated with CPC on the first, third, and fifth days and the concentration of IC50 was determined. The autophagic and apoptotic effects of CPC were examined by MTT assay, Acridine Orange, Giemsa, DAPI, MDC, real-time PCR, Western blot testing, and molecular docking. The cell viability was obtained on days 1, 3, and 5 as much as 50, 7.28, and 19%, respectively with a concentration of IC50 (100µM) of CPC. The staining results indicated that the treatment of HeLa cells with CPC had antitumor and autophagic effects. Results of RT-PCR showed that the expression of BAX, BAD, P53, and LC3 genes was significantly increased in the sample treated with IC50 concentration compared to the control sample whereas the expression of BCL2, mTOR, and ACT genes in cells was significantly decreased compared to the control group. Also, these results were confirmed by Western blotting. The data indicated the induction of apoptotic death and autophagy in the studied cells. The new compound of CPC has antitumor effects.
