Abstract:
Objective:To observe the expression of long non-coding RNA (lncRNA) PEBP1P2 in renal cell carcinoma (RCC) tissues and its effect on the proliferation and migration of RCC cells.Methods:The expression of PEBP1P2 in 51 RCC tissues and RCC cell lines was detected by real-time quantitative polymerase chain reaction (qPCR). The A498 cells with the lowest expression of PEBP1P2 were transfected, and the cells transfected with PEBP1P2 plasmid were used as the PEBP1P2 group, and the cells transfected with the negative control plasmid were used as the NC group. qPCR was used to detect the expression of PEBP1P2 in the two groups of cells. MTT assay and Transwell migration assay were used to detect the proliferation and migration ability of RCC cells. qPCR and Western blotting were used to detect the expression of caspase recruitment domain family member 10 ( CARD10) gene and NF-κB pathway protein, respectively. Measurement data were expressed as mean±standard deviation ( Mean± SD), and LSD- t test was used for comparison between groups. Results:The expression of PEBP1P2 in RCC tissues was lower than that in adjacent tissues ( t=4.89, P<0.01). The expression of PEBP1P2 in RCC cells was lower than that in normal renal tubular epithelial cells ( P<0.01). The expression of PEBP1P2 in A498 cells of the PEBP1P2 group and NC group was (11.01±1.26) and (1.06±0.19), respectively, and the PEBP1P2 group was significantly higher than that in the NC group ( t=7.81, P<0.01). Overexpression of PEBP1P2 significantly inhibited the proliferation of RCC cells ( P<0.05) and migration ability ( t=3.65, P<0.05). Overexpression of PEBP1P2 significantly suppressed the expression of CARD10 gene in RCC A498 cells ( t=6.83, P<0.01) and inhibited the transduction of NF-κB signaling pathway proteins. Conclusions:PEBP1P2 expression was significantly decreased in RCC tissues. Overexpression of PEBP1P2 significantly inhibited the proliferation and migration of RCC A498 cells. Its molecular mechanism is that PEBP1P2 down-regulates CARD10 gene expression and inhibits NF-κB signaling pathway.
