[PMID: 32559621 DOI: 10.1016/j.biopha.2020.110346] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 05/23/2020] [Accepted: 05/30/2020] [Indexed: 02/07/2023] Open
Abstract
PURPOSE The aim of this study was to research the molecular mechanism of lncRNA LINC01963 in pancreatic carcinoma progression. METHODS Total 67 pancreatic cancer patients diagnosed and undergoing pancreatic cancer surgery in our hospital from April 2018 to April 2019 were included in this study. Pancreatic cancer cell lines including PANC-1, CFPAC-1, BxPC-3, SW1990 and AsPC1 were used. Based on bioinformatics information, pIRES2-LINC01963 plasmid, siLINC01963, miRNA mimics, miRNA inhibitor or siTMEFF2 were transfected. qRT-PCR and western blot were used to detect the expression of LINC01963, miR-641 and TMEFF2. CCK8 and Colony formation assay were processed for proliferation. Flow Cytometry Assay was processed to detect cell cycle and apoptosis. Transwell experiment was undertaken for invasion and migration. Luciferase assay and RNA Immunoprecipitation assay were used to verify the binding site among LINC01963, miR-641 and TMEFF2. Tumorigenic experiment was processed to confirm the above mechanisms in vivo. RESULTS lncRNA LINC01963 was confirmed to be lower expressed in pancreatic carcinoma tissues and cell lines. By up-regulating the expression of lncRNA LINC01963 in pancreatic carcinoma cell lines, colony number, cell cycle, proliferation and invasion were inhibited, while apoptosis was improved. More importantly, shLINC01963 could improve development of tumor in vivo. Besides, lncRNA LINC01963 negatively regulated the expression of miR-641, while miR-641 negatively targeted TMEFF2. Both miR-641 mimic and siTMEFF2 could reverse the effects of lncRNA LINC01963 overexpression in vitro. CONCLUSIONS Long non-coding RNA LINC01963 inhibits progression of pancreatic carcinoma by targeting miR-641/TMEFF2.

Abstract
AIM To examine the expression of olfactory receptor family 2 subfamily W member 3 (OR2W3) in human pancreatic cancer (PC) and to analyze its clinical significance.
METHODS The expression of OR2W3 in 50 paraffin-embedded PC tissues and tumor adjacent tissues was detected by immunohistochemistry, and the relationship between the expression of OR2W3 protein and the clinicopathological factors was analyzed.
RESULTS The high expression and low expression rates of OR2W3 protein in PC tissues and tumor adjacent tissues were 78% (39/50) vs 12% (6/50) and 22% (11/50) vs 88% (44/50), respectively, and the differences between them were statistically significant (χ2 = 44.00, P < 0.05). Single factor analysis showed that the expression of OR2W3 was closely related to the degree of tissue differentiation, clinical stage, and lymph node metastasis of PC (P < 0.05).
CONCLUSION Overexpression of OR2W3 may play an important role in the development and progression of PC.
