ATAD2 and hepatocellular carcinoma: To obtain further insight into the functions of ATAD2 in HCC cell invasion and metastasis, the mRNA expression profile of siATAD2-transfected Huh7 cells was compared with that of si-negative transfected cells using a Human Tumor Metastasis RT2 ProfilerTM PCR Array containing 84 cell metastasis-related genes.
