Abstract:
AIM: To study the effects of cripto antisense oligodeoxynucleotide (ASODN) on telomerase activity in colon cancer LS-174T cells. METHODS: Colon cancer LS-174T cells were treated with cripto ASODN. The expression of cripto mRNA was studied using real-time PCR. The telomerase activity was detected by telomeric repeat amplification protocol enzyme-linked immunoabsordent assay (TRAP-ELISA). The growth of LS-174T cells was observed with soft agar. RESULTS: Cripto ASODN inhibited the growth of LS-174T cells in a dose-dependent manner in soft agar. Cripto ASODN decreased the telomerase activity in colon cancer LS-174T cells, and the effects of repression were time-and dose-dependent. CONCLUSION: Cripto may contribute to the activation of telomerase in colon cancer.
