Discussion
MiR-129-5p may suppress cell proliferation of OS by down-regulating Lnc712.
Methods
OS and paired non-tumor tissues were collected from 58 OS patients. Expression of Lnc712 and miR-129-5p in paired tissue samples was determined by RT-qPCR. Lnc712 and miR-129-5p expression was achieved in OS cells to study the interaction between them. Cell proliferation was analyzed by CCK-8 assay.
Results
Lnc712 was upregulated in OS and was inversely correlated with miR-129-5p. In OS cells, Lnc712 overexpression failed to significantly affect miR-129-5p, while miR-129-5p overexpression led to downregulated Lnc712. Cell proliferation showed that Lnc712 overexpression resulted in increased cell proliferation rate. MiR-129-5p overexpression played an opposite role and reversed the effect of Lnc712 overexpression.
