22q11 deletion syndrome (22q11DS) is a developmental anomaly caused by a microdeletion on human chromosome 22q11. Although mouse models indicate that Tbx1 is the gene responsible for the syndrome, the phenotypic spectrum of del22q11 patients is complex suggesting that gene–gene and gene–environment interactions are operative in delineating the pathogenesis of 22q11DS. In order to study the regulatory...
Summary Androgens play an important role in controlling the growth of the normal prostate gland and in the pathogenesis of benign prostate hyperplasia, and prostate cancer. Although testosterone is the main androgen secreted from the testes, dihydrotestosterone (DHT), a more potent androgen converted from testosterone by 5α-reductase isozymes, type I and II, is the major androgen in the prostate cells...
