MATN1-AS1 Promotes Tumour Metastasis and Sunitinib Resistance via E2F2 in Clear Cell Renal Cell Carcinoma.

ABSTRACT: It has become increasingly recognised that MATN1-AS1 is involved in multiple tumour development. The role of MATN1-AS1 in clear cell renal cell carcinoma (ccRCC), however, is still largely unrecognised. This study investigated the molecular functions of MATN1-AS1 in promoting ccRCC metastasis and sunitinib resistance. MATN1-AS1 was found to be mainly located in the cytoplasm and was upregulated in ccRCC, and a positive association was seen between greater levels of MATN1-AS1 expression and worse clinical outcomes. Downregulating MATN1-AS1 significantly hindered cell proliferation, migration, invasion and epithelial-mesenchymal transition (EMT). MATN1-AS1 promoted tumour growth and metastasis in vivo. Mechanismly, MATN1-AS1 targeted microRNA miR-214-5p, thereby upregulating E2F2 and promoti
