Mutations in the androgen receptor (AR) are associated with androgen insensitivity syndrome (AIS). Most AIS mutations affect either hormone, DNA or coactivator binding to the AR, but for some mutations there was no explanation yet. Recently, a crystal structure revealed a possible dimerization interface in the ligand binding domain (LBD) of the AR.1 To test the physiological relevance of this LBD dimerization, we generated a mouse model with a W732R mutation located...

Most mutations found in the androgen receptor (AR) are associated with some form of androgen insensitivity syndrome (AIS), and correlate with a loss of either hormone, DNA or coactivator binding. For some mutations in the ligand binding domain (LBD) of the AR, it is unclear what the underlying mechanism of the AIS could be. In the beginning of 2017, a new dimerization interface was uncovered in a crystal structure of the ligand-binding domain (LBD) which provides a possible me...

Background and aim: Androgens and glucocorticoids are regulated via the hypothalamus-pituitary-gonadal (HPG) and hypothalamus-pituitary-adrenal (HPA) axis, respectively. We aimed to check possible interference of androgen deprivation with the HPA axis and circulating glucocorticoid levels. Androgen deprivation is most widely used in the treatment of prostate cancer, but is also applied in gender-affirming care and males with hypersexual disorder. Current insig...
