To verify whether Lnc-LALC can promote the invasion and metastasis of CRC by regulating the expression of LZTS1, we randomly selected 40 CRC tissues in two groups(20 samples in High group and 20 samples in Low group, the two groups were divided according to their average Lnc-LALC expression level in tumor tissues) and performed qRT-PCR to detect the expression level of Vimentin (a mesenchymal marker) and E-cadherin (an epithelial marker) in these two groups. This evidence concerns the gene LZTS1 and colorectal carcinoma.
