To investigate the inhibitory effect of LNCNA-NEA1 on pancreatic cancer development and progression via spongiosa miR-146b-5p/TRAF6, 60 pancreatic cancer patients diagnosed from December 2017 to December 2019 were selected as a general source of information. Real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) was used to detect the expression level of NEAT1 in cancerous and adjacent non-cancerous tissues. Cell counting kit-8 (CCK-8) and transwell were used to determine the effect of LNCNA-NEA1 on the proliferation and migration of pancreatic cancer cells (Panc-1). The results of dual luciferase reporter gene assay showed that nea 1 could target and regulate the expression of spongy miR-146b-5p/TRAF6, and reducing the expression of spongy miR-146b-5p/TRAF6 could reverse the inhibitory effects of nea 1-siRNA on proliferation, migration and invasion of pancreatic cancer cells. Therefore, it was concluded that knockdown of nea 1 could inhibit the proliferation, migration and invasion of pancreatic cancer cells by upregulating the level of miR-146b-5p/TRAF6, and the expression of lnc RNA-nea 1 could be used as an indicator for preoperative diagnosis and postoperative prognosis of pancreatic cancer patients. .
