title: Coronary artery disease susceptibility gene ADTRP regulates cell cycle progression, proliferation, and apoptosis by global gene expression regulation.
abstract: The ADTRP gene encodes the androgen-dependent TFPI-regulating protein and is a susceptibility gene for contrary artery disease (CAD). We performed global gene expression profiling for ADTRP knock-down using microarrays in human HepG2 cells. Follow-up real-time RT-PCR analysis demonstrated that ADTRP knock-down regulates a diverse set of genes, including upregulation of seven histone genes, downregulation of multiple cell cycle genes (CCND1, CDK4, and CDKN1A), and upregulation of apoptosis genes (CASP7 and PDCD2) in HepG2 cells and endothelial cells. Consistently, ADTRP increases the number of S phase cells during cell cycle, promotes cell proliferation, and inhibits apoptosis. Our study provides novel insights into the function of ADTRP and biological pathways involving ADTRP, which may be involved in the pathogenesis of CAD.
