Cancer&Entry Information

Cancer Name	colon cancer
ICD-0-3	C18
Methods	qPCR, Western blot, in vitro knockdown, etc.
Sample	CC tissues, human CC cell lines SW480, SW620, HCT116 and HT-29
Expression Pattern	up-regulated
Function Description	analyzed the lncRNA expression patterns in Gene Expression Omnibus (GEO) datasets and the Cancer Genome Atlas (TCGA) RNA-seq datasets, and found that the expression level of AFAP1-AS1 was significantly elevated in CC tissues. High levels of AFAP1-AS1 were associated with poor disease-free survival and overall survival in CC patients. In vitro experiments demonstrated that AFAP1-AS1 knockdown significantly inhibited the cell invasive and migration capability in CC cell line HT-29. AFAP1-AS1 knockdown also increased the expression of E-cadherin and ZO-1 while inhibited the expression of Vimentin, MMP9, ZEB1 and ?-catenin, suggesting that AFAP1-AS1 is involved in the epithelial-mesenchymal transition (EMT) process of CC. Further studies confirmed that AFAP1-AS1 knockdown also affected the actin-cytokeratin signaling pathway. Thus, AFAP1-AS1 might be a potential novel diagnostic marker and therapeutic target for CC.
