Abstract:
:Cellular senescence is a state of irreversible cell growth arrest. Increasing evidence suggests that cellular senescence contribute to tumour suppression in vivo. However, only a few anti-cancer drugs have been discovered to induce cellular senescence. Searching for new compounds which can inhibit cancer cell growth by inducing senescence is becoming one of the most attractive research fields. To test the effects of candidate compounds on cancer cell growth, cell proliferation assays, senescence-associated β-galactosidase (SA-β-gal) staining, and flow cytometry assay were performed. Immunofluorescence, western blot, and qRT-PCR experiments were used to further study the molecular mechanisms of the candidate compounds. We demonstrated that a pyridine derivative, 4-(4-fluorophenyl)-2-phenyl-5, 6, 7, 8-tetrahydroquinoline (FPTHQ), from a pool of 46 compounds can induce senescence of ovarian cancer cells in a dose-dependent manner. FPTHQ caused growth inhibition by inducing G0/G1 cell cycle arrest in A2780 cells. Increased activities of SA-β-gal were observed in FPTHQ-treated A2780, OVCAR-3 and SKOV-3 cell lines. In addition, FPTHQ treatment increased the protein levels of MMP3 and the mRNA levels of IL-6 and IL-8 in A2780 cells, indicating the appearance of senescence-associated secretary phenotype (SASP) in the cells. Furthermore, we found that p21 was up-regulated and DNA damage was accumulated in FPTHQ-treated ovarian cancer cells. So far, our data suggest that FPTHQ can induce senescence in multiple ovarian cancer cell lines through activation of p21 signalling pathway by causing excessive DNA damage.
