DCLK1 and colorectal carcinoma: To determine the clinical relevance of CXCR7 expression with EMT, we analyzed the correlation of the expression of CXCR7 (ACKR3) with EMT markers and DCLK1 in human CRC tissues by Gene Expression Profiling Interactive Analysis (GEPIA) (http://GEPIA.cancer-pku.cn/index.html) using TCGA datasets.
