CircRNA is conserved amongst species and is steady in blood, saliva, and exosomes. These characteristics might enable circRNA to become employed in the diagnosis of illnesses, including cancer. Though quite a bit of study is focusing on circRNA, many inquiries remain unanswered. CircKRT7 is derived from KRT7 gene, which is frequent findings in numerous cancers and constitutes a prognostic factor. Nevertheless, no investigation has focused on circKRT7 and its biological function in ovarian cancer. Within this study, we found that circKRT7 is abnormally extremely expressed in ovarian cancer. In order to verify the function and mechanism of circKRT7 in ovarian cancer, we employed cell and animal experiments to confirm. It was found that overexpression of circKRT7 can block the degree of miR-29a-3p and market the proliferation and invasion of ovarian cancer cells. As a tumor suppressor, miR-29a-3p has been shown to inhibit the progression of thyroid tumors, hepatocellular carcinoma, and glioma.147 Moreover, circFOXO3 could market prostate cancer progression by sponging miR-29a-3p.18 Right here we found that miR-29a-3p can inhibit the expression of COL1A1, and circKRT7 can precisely release COL1A1 by adsorbing miR-29a-3p, which ultimately urges the proliferation and metastasis of ovarian cancer cells. Most malignant tumors derived from epithelial tissues. Epithelial tissue-derived tumors endow mesenchymal properties by means of EMT pathway and turn out to be far more malignant and metastatic.19,20 Here we come across that the expression of vimentin was considerably up.
