About

Dr. Hofland’s translational research focuses on the regulatory mechanisms of steroid hormone production, with special emphasis on cancer. This has involved elucidating the role of circulating (ACTH, arginine-vasopressin) and local factors (activin, inhibin) on adrenocortical production of aldosterone, cortisol and androgens in health and diseases, such as adrenal hyperplasia, adenomas and cancer. The other main research theme comprises the study of intratumoral steroidogenesis in prostate cancer as a possible cause for castration resistance and disease progression. His interdisciplinary research has aimed to unravel the complex interplay between circulating adrenal androgens and intracrine androgen conversion. His current fellowship at CEDAM serves to investigate the contribution of a novel androgen synthesis pathway within prostate cancer cells to resistance to castration and second line hormonal treatments. This will be accomplished through a steroid metabolome analysis in translational models, giving a unique and complete insight into androgen metabolism in prostate cancer.
