MicroRNAs are important regulators in the growth and metastasis of ovarian cancers. Many assays were established to identify the role of miR-144-3p in ovarian cancer cells and its interaction with COX-2 and chemokines (CXCR4 and CXCL12). The ovarian cancer cells (OVCAR-3 and SKOV-3) were transfected with Anti-miR-144 to downregulate the miR-144-3p and cultured for 36 h. We herein examined the cell viability, colony formation, cell migration, COX-2 reporter activity, the protein expressions of CXCR4, CXCL12, COX-2, VEGF, Caspase-3, BAX and Bcl-2. We have observed that the suppression of miR-144-3p significantly increased the cell proliferation and migration and decreased the apoptosis. Moreover, the downregulation of miR-144-3p markedly increased the COX-2, CXCR4, CXCL12 and VEGF expression in OVCAR-3 and SKOV-3 ovarian cancer cells. In conclusion, miR-144-3p may play important roles in the regulation of chemokine receptor CXCR4 and its ligand CXCL12 in the progressive ovarian tumors expressing COX2. These data suggests that miR-144 has the novel therapeutic targets for the cancer therapy and cancer prevention.
