For example, miR-1207-5p targeting CSF1 inhibits the implantation and metastasis of lung cancer [39]; miR-148b targets CSF1 and other genes that inhibit the development of breast cancer [40]; miR-142-3p targets CSF1 to induce the conversion of monocytes to macrophages [41]; and miR-214 targets CSF1 to regulate the proliferation, invasion, and migration of gastric cancer cells [42]. The gene discussed is CSF1; the disease is breast carcinoma.
