To assess the role of YAP1 in CRC, we first quantitated YAP1 gene expression levels in CRC biopsies and normal colorectal tissues using a microarray dataset, GSE20916, containing 24 normal colorectal tissues and 81 CRC tissue biopsies, with the Affymetrix HG U133 Plus 2.0 GeneChip platform. Here, YAP1 is linked to colorectal carcinoma.
