Tumor-suppressor microRNA-151-5p regulates the growth, migration and invasion of human breast cancer cells by inhibiting SCOS5.

ABSTRACT: Breast cancer is a prevalent malignancy in women and its incidence is increasing at an alarming rate. Breast cancer treatment is mainly obstructed by late diagnosis due to lack of biomarkers, dearth of therapeutic targets, constant relapses, drug resistance, and adverse effects of the chemotherapy. MicroRNAs (miRs) have shown exceptional potential to act as therapeutic agents for treatment of cancer. This study was designed to investigate the role and therapeutic implications of miR-151-5p in breast cancer. The results of the present study revealed that miR-151-5p is significantly downregulated in breast cancer tissues and cell lines. Overexpression of miR-151-5p in SK-BR-3 and CAMA-1 cells inhibits their proliferation and colony formation. Wound heal and transwell assays showed that miR-1
