androgen receptor signaling pathway prostate induction obsolete activation of prostate induction by androgen receptor signaling pathway https://github.com/geneontology/go-ontology/issues/28041 true activation of prostate induction by androgen receptor signalling pathway This term was obsoleted because it represents a GO-CAM model. GO:0060520 biological_process OBSOLETE. The series of molecular signals initiated by androgen binding to its receptor in the urogenital sinus mesenchyme that initiates prostate induction. Prostate induction is the close range interaction of the urogenital sinus mesenchyme and the urogenital sinus epithelium that causes the cells of the urogenital sinus epithelium to change their fates and specify the development of the prostate gland.
