In addition, western blotting indicated that miR-885-3p suppressed the progression of breast cancer cells by downregulating the expression level of PCNA and the expression levels of CDK2/CCNE1 and CDK4/6/CCND1 (Figure 4G–4I) (Student’s t test, p < 0.05). The gene discussed is CCND1; the disease is breast carcinoma.
