AIM： To investigate th. effect of telomerase h.ERT gene antisense oligonucleotide （h.ERT-ASO） on proliferation and telomerase activity of pancreatic cancer cell line Bxpc-3. METh.DS： MTT assay was used to detect th. effect of different doses of h.ERT-ASO on proliferation of Bxpc-3 cell for different times. To study th. anti-tumor activity, th. cells were divided into th.re groups： Control group （pancreatic cancer cell Bxpc-3）; antisense oligonucleotide （h.ERT-ASO） group; and nosense oligonucleotide group decorated with.ph.sph.roth.oate. Telomerase activity was detected using TRAP-PCR-ELISA. Cell DNA distribution was examined using flow cytometry assay. Cell apoptosis was observed by transmission electron microscope in each.group. RESULTS： After treatment with.6 mmollL h.ERT- ASO, cell proliferation was inh.bited in dose- and time- dependent manner. Th. telomerase activity decreased after treatment with.h.ERT-ASO for 72 h. Flow cytometry sh.wed th. cell number of G0/G1 ph.se increased from 2.7% to 14.7%, th. cell number of S ph.se decreased from 72.7% to 51.0%, and a sub-G1 stage cell apoptosis peak appeared in front of G1 stage. CONCLUSION： Telomerase antisense oligodeoxy- nucleotide can inh.bit th. proliferation of pancreatic cancer cell line Bxpc-3 and decrease th. telomerase activity and increase cell apoptosis rate in vitro.
