Fig. 2From: Circ_0000140 restrains the proliferation, metastasis and glycolysis metabolism of oral squamous cell carcinoma through upregulating CDC73 via sponging miR-182-5p Effects of circ_0000140 overexpression on the proliferation, migration and invasion of OSCC cells. CAL-27 and SCC-4 cells were transfected with circ_0000140 overexpression vector or vector. a The expression of circ_0000140 in CAL-27 and SCC-4 cells was detected by qRT-PCR to evaluate transfection efficiency. b Colony formation assay was performed to measure the number of colonies in CAL-27 and SCC-4 cells. c, d The number of migrated and invaded CAL-27 and SCC-4 cells was determined by transwell assay. e, f WB analysis was performed to detect the protein levels of ki67, MMP-2 and MMP-9 in CAL-27 and SCC-4 cells. ** P < 0.01Back to article page
