In glioblastoma, miRNA‐127‐3p targets and inhibits SEPT7, which is a negative regulator of cell migration and invasion.44 Upregulation of miRNA‐127‐3p was observed in tumor initiating cells in lung carcinoma and also in circulating blood in breast cancer patients compared to that of healthy individuals.45, 46 Increased expression levels of serum miRNA‐4736 was observed in patients with various sarcomas. This evidence concerns the gene SEPTIN7 and breast cancer.
