Our study reveals a novel role for high-expressed KDM2A in colorectal adenocarcinoma cell growth, and that the expression of KDM2A is associated with that of cyclin D1 in colorectal adenocarcinoma.
In the present study, c-myc and cyclin D1 gene amplification was examined in 76 primary and metastatic liver carcinomas using formalin-fixed paraffin-embedded tissue sections and a differential polymerase chain reaction procedure. c-myc and cyclin D1 gene amplification was detected in 15 (33%) and two (4%) of 46 hepatocellular carcinomas (HCC), one (10%) and 0 (0%) of 10 intrahepatic cholangiocarcinomas (ICC), one (33%) and 0 (0%) of three combined hepatocellular and cholangiocarcinomas (HCC + ICC), and nine (56%) and three (19%) of 16 metastatic lesions to the liver from colorectal adenocarcinoma (MCA), respectively.
