LncRNA RP3-326I13.1 promotes cisplatin resistance in lung adenocarcinoma by binding to HSP90B and upregulating MMP13.

ABSTRACT: Cisplatin (DDP) resistance has become the major obstacle in the therapy of malignant tumors, including lung adenocarcinoma (LAD). Long non-coding RNAs (lncRNAs) were confirmed to be related to DDP-resistance. Studies have shown that RP3-326I13.1 (also known as PINCR) could promote the progression of colorectal cancer, and RP3-326I13.1 knockdown could induce hypersensitivity to chemotherapy drugs. While the function of RP3-326I13.1 in LAD is unclear, therefore, this study aimed to research the biological function and related molecular mechanisms of RP3-326I13.1 in DDP-resistance of LAD. QPCR analysis found that RP3-326I13.1 was highly expressed in A549/DDP cells and LAD tissues. Cytological assays found that RP3-326I13.1 pro-moted the proliferation, migration, invasion, and DDP-resistance o
