MicroRNA ‑192 inhibits cell proliferation and induces apoptosis in human breast cancer by targeting caveolin 1.

MicroRNA‑192 inhibits cell proliferation and induces apoptosis in human breast cancer by targeting caveolin 1. Oncol Rep. 2019 Aug 30;: Authors: Chen P, Feng Y, Zhang H, Shi X, Li B, Ju W, Yu X, Zhang N, Luo X Abstract It has been demonstrated that microRNA‑192 (miR‑192) serves important roles in different cancer types, including breast cancer, prostate cancer and colorectal cancer. However, its biological role and function in breast cancer remains largely unknown. The present study aimed to determine the role of miR‑192 in breast cancer. In the present study, one normal breast and two breast tumor cells lines were used, which included the normal mammary fibroblast cell line Hs578Bst, a more aggressive breast tumor cell line MDA‑MB‑231 and a less aggressive breast tumor cell line MCF‑7. The effect of miR‑192 on proliferation of breast cancer cells was detected with an MTT assay. Western blot analysis was performed to determine protein expression of caveolin 1 (CAV1). A lentiviral vector that overexpresses pre‑miR‑192 and control lentiviral packaging plasmids were used in the present study. The Student's t‑test was performed to analyze the significance of differences between samples. In the present study, it was determined that the expression of miR‑192 is downregulated in breast cancer, compared with the adjacent normal tissues. Overexpression of miR‑192 significantly inhibited cell proliferation, and induce...
