Expression of circulating miR ‐17, miR‐25, and miR‐133 in breast cancer patients

This study aimed to investigate some miRNAs in the serum of patients with breast cancer compared with the control group. Total RNA was extracted from the serum of patients with breast cancer and healthy volunteers. The expression levels of miRNAs and the genes were assessed using real ‐time reverse transcriptase‐polymerase chain reaction with specific primers. Our data showed that miR‐25 and miR‐133 were downregulated, and miR‐17 was upregulated in patients with breast cancer. Upregulation of miR‐17 is related to the poor survival time and increased cell proliferation . The reduced expression of miR‐133 and miR‐25 is significantly associated with clinical stage, metastasis, and survival time of patients with breast cancer. Expressions of miRNAs miR‐17, miR‐25, and miR‐133 are altered in patients with clinical stage, metastasis, poor survival time.
