The regulation of parathyroid hormone (PTH) secretion is of fundamental importance for calcium homeostasis and in mineral conditions affecting bone and the kidneys. Whilst it is clear that the calcium-sensing receptor (CaR) represents the key controller of PTH secretion by suppressing its secretion, the way the CaR works remains unclear. Indeed, it is still not clear how elevated intracellular calcium concentration (Ca2+i) appears to suppress PTH secretion in parathyroid gland while stimulating hormone / neurotransmitter secretion in many other cell-types. Furthermore, the pulsatility of PTH secretion, which is vital for bone formation, remains poorly understood. Therefore, this project aims to shed light on both the basic physiology of mammalian calcium homeostasis as well as helping us to understand the development of osteoporosis and CKD-MBD (bone mineral disease of chronic kidney disease). This project involves live cell imaging (including intracellular calcium and cAMP imaging) as well as cell transfection with receptors, signalling modulators and siRNAs for selectively knocking down expression of CaR signal regulators.
Training/techniques to be provided:
Intracellular signalling measured using a) FRET-based cell imaging and b) Epifluorescence microscopy
Cell culture, transfection, gene knockdown and cell assay.
Molecular techniques including Immunoblotting, Immunofluorescence, RT-PCR and mutagenesis
Use of receptor allosteric modulators and consideration of GPCR signal and tissue bias.
Candidates are expected to hold (or be about to obtain) a minimum upper second class honours degree (or equivalent) in a related area/subject. Candidates with previous laboratory experience, particularly in cell culture and molecular biology, are particularly encouraged to apply.
