Background: The cyclic GMP-AMP synthase stimulator of interferon genes (cGAS-STING) signalling pathway is an element of the innate immune response and is activated by the presence of DNA in the cytosol. Triggering of this immune response may occur in the setting of infection or neoplasia. Activation of this pathway results in phosphorylation of interferon regulatory factor 3 and downstream transcription of cytokines such as interferon β and interleukin-6. Polyinosinic:pol...

Pituitary neuroendocrine tumours (PitNETs) are heterogeneous and have limited biomarkers to predict their behaviour, thus making their prognostication difficult. Ki-67 is a protein expressed in active phases of the cell cycle and is one of the biomarkers utilized in routine assessment of PitNET tissue. Current European Society of Endocrinology recommendations advise that histopathological analysis of PitNETs should as a minimum include Ki-67 proliferation index and anterior pi...

In Northern Ireland, the sole tertiary referral centre for pituitary disease which includes neurosurgery and endocrinology for ~1.9 million people, is based in the Royal Victoria Hospital, Belfast. A retrospective study has been commenced to examine clinical, biochemical, histopathological and radiological data for all patients operated on across an approximately 20 year period in Northern Ireland. Ethical approval was obtained from the Northern Ireland Biobank (study num...
