Peter King graduated from Cambridge University with a degree in Natural Sciences. He was awarded a PhD by the Imperial Cancer Research Fund (now CRUK) on transcriptional regulation of the human beta interferon gene, with studies performed at Lincolns Inn Fields and St Georges Hospital Medical School, London. He joined the Molecular Endocrinology Department at Bart’s in 1997, was appointed to a lectureship in 2001 and was promoted to Senior Lecturer in 2009.

The main aim of my research is to understand the molecular mechanisms that control adrenal development and differentiation during organogenesis, and homeostasis in the adult. The adrenal is a vitally important gland that controls both the stress response and blood volume and, as such, disorders of development and function can be fatal without lifelong therapeutic intervention. Previous research has identified sonic hedgehog (Shh) as an important signalling molecule in adrenal development and has proposed that the cells that produce it and/or the signal receiving cells in the adrenal capsule, are candidates for stem/progenitor cells in development and in the adult. Current research is focussing on potential signalling pathways that control Shh signalling or are downstream of it in the adrenal, for example, Wnt/b catenin, FGF and Dlk1 pathways, and the control that these exert over adrenal remodelling in the adult, which is the concerted response of the gland to stress or changes in blood volume that require the rapid recruitment of new steroidogenic cells. It is anticipated that these will prove to be novel targets for treatment of hypertension.
More recently we have begun to investigate the role of primary cilia (see also Chapple) in adrenal development and function and the shared origins of adrenal and testicular steroidogenic (Leydig) cells, as well as continuing to study signalling pathways that control steroidogenesis and are involved in adrenal cell growth and cancer.
Dlk1 mRNA and DLK1 protein is a marker of the outer ZU
Adult rat adrenal sections were processed for Dlk1 NR-ISH (B) and then stained with antibodies to CYP11B1 (B1) and CYP11B2 (B2) (A, both green). The Dlk1 signal was pseudocoloured to red (C) and the merged image (D) assembled. White arrows indicate CYP11B2 positive/Dlk1 negative cells while the yellow arrows indicate a minority of double positive cells. The same result was obtained with an anti-Dlk1 antibody (inset). Taken from Guasti et al. (2013), Endocrinology 154: 4675-4684.
