Abstract 【Objective】 To investigate the effects of miR-181a and miR-138 on the proliferation of chondrosarcoma cells. 【Methods】A total of 20 samples of osteosarcoma and 20 samples of chondrosarcoma tissues were collected. qRT PCR was used to detect the expression levels of miR-181a and miR-138. miRNA mimetics were used to promote the expression of miR-181a and miR-138 in chondrosarcoma cells SW1353. Cell counting was used to detect the effects of miR-181a or miR-138 overexpression alone or in combination on the growth ability of SW1353 cells. The binding sites of miR-181a, miR-138 and RAS family associated domain protein 8 (RASSF8) were predicted using the TargetScan database, and gene experiments were validated using dual luciferase reporter technology.【Results】Compared with chondrosarcoma tissue, the expression of miR-181a and miR-138 was significantly upregulated in chondrosarcoma tissue (P<0.05); Compared with the negative control group, the cell growth ability of the miR-181a and miR-138 overexpression groups was significantly increased (P<0.05), and the combined overexpression group of miR-181a and miR-138 showed the most significant upregulation of cell growth ability; According to predictions, both miR-181a and miR-138 have binding sites with RASSF8; Compared with the cotransfected wild-type RASSF8+scaffold group, the luciferase activity in the cotransfected wild-type RASSF8+miR-181a group and wild-type RASSF8+miR-138 group was significantly reduced (P<0.05); Compared with the cotransfected mutant RASSF8+scaffold group, there was no significant change in luciferase activity in the cotransfected mutant RASSF8+miR-181a group and the mutated RASSF8+miR-138 group (P>0.05). 【Conclusions】miR-181a and miR-138 may promote the growth of chondrosarcoma cells by inhibiting RASSF8.
