Overweight and obesity is an escalating global health problem, affecting 40% of the population and being the 5th largest cause of death worldwide. Treatment options are limited, with pharmaceutical approaches being inadequate and the success of bariatric surgery being limited by its invasive nature. The regulation of appetite by small bioactive compounds in the gastrointestinal tract is an important target in antiobesity research. Metabolites from diet and both host and microb...

Cis-gender females are known to mount stronger humoral immune responses than cis-gender males. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system.Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ‘switches’ from early IgM/IgD classes to IgG/IgA/IgE. Whilst important in infection/vaccine responses; switched isot...

Introduction: YDC is a partnership of four hospital trusts;Kings College Hospital, Princess Royal University Hospital, Lewisham University Hospital and Evelina London Children’s Hospital,caring for a total of 492 children and young people with diabetes. Most young people are on conventional long acting insulin (Levemir and Glargine), but increasingly, poorly controlled patients (HbA1C>100 mmol/mol) with high admission rates are being switched to insulin Degludec due t...

By exploiting the canonical function of the sodium iodide symporter (NIS), ablative radioiodide therapy is an effective treatment for thyroid cancer. However, a subset of patients are unable to accumulate sufficient radioiodide due to decreased expression and/or plasma membrane localisation of NIS. Radioiodide therapy has been proposed as a viable treatment for breast cancer, but is hampered by low levels of NIS membrane localisation. Currently, the regulation of NIS trafficki...

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder characterised by the combined occurrence of parathyroid tumours, and neuroendocrine tumours (NETs) of the pituitary and pancreas. MEN1 is caused by mutations of the tumour suppressor gene MEN1, and MEN1 germline mutations are found in >75% of MEN1 patients. The remaining 25% of patients may have mutations involving as yet unidentified gene...

Idiopathic intracranial hypertension (IIH) is a condition of unknown aetiology characterised by raised intracranial pressure, chronic headaches and blindness. Akin to polycystic ovary syndrome (PCOS), IIH patients are almost exclusively obese females of reproductive age. A distinct androgen excess profile has been noted in PCOS. Here, we aimed to delineate androgen metabolism in IIH compared to PCOS and simple obesity.Women w...

Worldwide, ˜300,000 new cases of differentiated thyroid cancer are reported per annum and thyroid cancer now represents the most rapidly increasing cancer in the US and in the UK. In general terms, outcome is good (10-year survival >90%). However, up to 25% of patients develop local or regional recurrences, and have a significantly reduced life expectancy. We hypothesise those thyroid tumours which subsequently recur display a distinct pattern of driver ...
