Inhibitory Effects of Arsenic Trioxide on Telomerase Activity in Melanoma A375 Cells |
| |
Abstract: | BACKGROOND&AIM: To study the inhibition of telomerase activity in melanoma A 375 cells by arsenic trioxide(As 2 O 3 ).We analyzed the inhibition of telomerase activity in A 375 cells by TRAP_ELISA and TRAP_PAGE_silver staining. MATERIAL AND METHODS: TRAP_ELISA and TRAP_PAGE_silver staining. RESULTS: As 2 O 3 can inhibit telomerase activity in A 375 cells and the rates of inhibition have both dose_dependent and time_dependent manner. CONCLUSION: As 2 O 3 can inhibit telomerase activity in telanoma A 375 cells.The TRAP_ELISA assay showed a dose_response and a time_response relationship for inhibition of A 375 cells by As 2 O 3 .The inhibition was enhanced with the increase of As 2 O 3 concentration or prolong of co_culture time. |
