LINC00022 promoted angiogenesis in CRC. After HCT116, DLD1, and CaCo-2 cells were infected with LINC00022 low expression lentivirus or high expression lentivirus, the level of VEGFA in the cell supernatant was detected by the detection kit (a); The mRNA and protein levels of VEGFA in HCT116, DLD1, and CaCo-2 cells were measured using qRT-PCR and Western blot, respectively (b and c); The number of cavity formation was calculated (d). Scale bar = 200 μm. Data were presented as mean ± standard deviation (SD). N = 3. **P < 0.01 and ***P < 0.001 vs Lv-anti-NC group or Lv-NC group. VEGFA, vascular endothelial growth factor A; qRT-PCR, quantitative Real-time PCR
