About the research

Pituitary tumour research focuses on hypothalamo-pituitary disease including pituitary and other sellar/parasellar tumours, hypothalamic dysfunction and the consequences of pituitary tumour treatment including hypopituitarism, employing clinical and translational approaches (Karavitaki). We are particularly interested in the identification of biomarkers of diagnostic, prognostic and therapeutic significance; systemic biobanking of patients and detailed phenotyping facilitate these aims (Birmingham Pituitary Biobank). In collaborative studies, we look at the pathogenesis of craniopharyngiomas and pituitary adenomas, long-term outcomes of various management approaches and prognostic parameters. Novel treatments for pituitary tumours and relevant clinical trials are further areas of our work.

About the research

Thyroid tumour research comprises a large programme (McCabe) aimed at improving radioiodine treatment of aggressive thyroid cancers via new understanding of sodium iodide symporter (NIS) trafficking. Via novel high-throughput drug screening, several drugs have been identified that increase NIS function at the plasma membrane, now systematically appraised in thyroid and breast cancer models. Recent work has identified unique gene and miRNA changes in early thyroid cancer recurrence, now evaluated by Nanopore DNA sequencing of fine needle aspirants for rapid detection of patient driver mutations. Vicki Smith investigates the roles of the understudied proto-oncogenes PBF and PTTG in thyroid and breast cancer, focussing on cellular signalling pathways and their disruption in neoplasia. Her current research examines the interplay between signal transduction and actin dynamics that drives tumour cell motility and invasion.

About the research

Adrenal tumour research focusses on both common conditions (adrenal incidentaloma – 5% of the population with metabolic disease burden, Conn’s syndrome affecting 10% of hypertensives) and rare but devastating adrenocortical carcinoma (ACC; 5-year survival rate 30-40%). Through the European Network for the Study of Adrenal Tumours (ENSAT) we have access to a global network of other internationally leading teams. Combining mass spectrometry-based urine multi-steroid profiling and machine learning methods for data analysis, we have used this novel urine steroid metabolomics approach to uncover prevalent cortisol excess in mineralocorticoid hypertension and to develop a biomarker tool for the non-invasive diagnosis of ACC, recently validated in an ENSAT multi-centre trial led by Arlt with Chortis (EURINE-ACT), now in the process of roll-out to clinical practice.

Ronchi has developed novel applications of targeted molecular analyses including a liquid biopsy approach for rapid detection of ACC recurrence and also uses novel cell and tissue-based models for the identification of novel therapeutic targets for ACC treatment, and collaborating with Calebiro to investigate GPCR alterations in cortisol excess. Elhassan and Calebiro are collaborating in studying receptor signalling in adrenocortical tumours utilising state-of-the-art methodology, such as live-cell imaging, with the aim to understand tumour pathogenesis. Additional work targets the metabolic impact of mild autonomous cortisol excess (MACE) in adrenal incidentalomas (Prete, Arlt, Manolopoulos) and the significance of mineralocorticoid excess in hypertension (Lang, Prete, Arlt).

About the research

Our research into endocrine-related cancers spans the understanding of basic steroidal metabolism to drug discovery and translational clinical medicine. By using our Steroid Metabolome Analysis Core, we are investigating how mapping steroid output from endocrine-related cancers can inform new diagnostic tests and drug discovery opportunities (Arlt, Jeevan Foster). Studies have also highlighted oestrogen metabolism through 17β-hydroxysteroid dehydrogenases as a potential driver of colorectal cancer and thus opening up this malignancy for novel approaches for new treatment (Foster).

About the research

One particular strength is our ability to develop innovative microscopy methodologies (Calebiro), in combination with new biosensors, to monitor receptor signalling directly in living cells and tissues with unprecedented spatiotemporal resolution. This is combined with novel mathematical and computational approaches to extract quantitative information from complex imaging data and model receptor signalling at both molecular and cellular level.
