Many of the most potent human oncoproteins belong to a class of proteins called transcription factors, but designing small molecule drugs that target transcription factors is a major challenge. An international team of researchers from the Institute for Research in Biomedicine in Barcelona, the Max Planck Institute for Molecular Genetics, BC Cancer (University of British Columbia) and other institutions has now discovered a potential way to target the androgen receptor, the most prominent oncogenic transcription factor in prostate cancer, based on its propensity to form droplets also known as condensates. ...
