The human prostate is a gland of the male reproductive tract which, together with the seminal vesicles, is responsible for most seminal fluid production. In Drosophila, the male accessory glands make many major seminal fluid components and are in many aspects the functional equivalent of the human prostate. Mechanisms driving prostate epithelial tumorigenesis, such as basal epithelial cell extrusion, are being studied in flies using the male accessory gland. In some cases, the model involves expression in the accessory glands of established drivers of tumorigenesis in flies (for example, Ras85DV12; see FBhh0000474).
For reviews promoting this type of prostate cancer model, including detailed descriptions of the functional analogies of the human prostate and Drosophila male accessory glands, see Wilson et al., 2017 (FBrf0234322) and Rambur et al., 2021 (FBrf0251378).
