| Abstract: | AIM: To inhibit 293T cell proliferation by reducing miR-20 and miR-106 expression with antisense RNA. METHODS: Antisense RNA (or antisense oligonucleotides, ASO) specific to miR-20 and miR-106 was synthesized, and the 293T cells were treated with these antisense RNA. Then, the cell proliferation derived from suppression of antisense RNA was studied by microscopy and fluorescence-activated cell sorter. The expression of miRNA and its target gene Rb were analyzed by real-time PCR and ELISA, respectively. RESULTS: Our results showed that ASO could inhibit the expression of miR-20 and miR-106 effectively and inhibit 293T cell proliferation. The results also demonstrated that ASO specific to miR-106 could up-regulate anti-oncogene Rb expression. CONCLUSION: ASO could inhibit 293T cell proliferation by inhibiting miRNA expression and up-regulating Rb expression. |
