AUF1/heterogeneous nuclear ribonucleoprotein D (hnRNPD) is an adenylate uridylate-rich elements (ARE) binding protein, which regulates the mRNA stability of many genes related to growth regulation, such as proto-oncogenes, growth factors, cytokines and cell cycle regulatory genes. Several studies demonstrated AUF1 expression in kidneys, liver, lymphoid tissues and melanocytes, and its involvement in apoptosis, tumorigenesis and development by its interactions with AREs bearing...

Skeletal muscle is the principal tissue responsible for insulin-stimulated glucose disposal and is thus the major site of peripheral insulin resistance. Urocortin 2 (Ucn2), a corticotropin releasing factor (CRF) family member and the type 2 CRF receptor (CRFR2) are highly expressed in skeletal muscle. To determine the physiological role of Ucn2, we generated mice deficient in this peptide. Using glucose and insulin tolerance tests and hyperinsulinemic euglycemic glucose clamp ...

Standard therapy (ST) for chronic hypoparathyroidism (HPT) includes calcium and active vitamin D supplementation, which can be associated with an increased risk of renal complications. This study compared renal function change, assessed by estimated glomerular filtration rate (eGFR) over 5 years between HPT patients receiving rhPTH1-84 as an adjunct to ST and a historical control cohort without rhPTH1-84. rhPTH1-84-treated HPT patients were selected from two single-arm, long-t...

Significant knowledge gaps exist regarding the humanistic effects of chronic hypoparathyroidism (HPT), a rare, debilitating condition. We provide interim results from a global survey conducted to characterise the burden associated with chronic HPT from the patient perspective. An anonymous, self-reported survey (online or paper) was conducted in patients with chronic HPT, not adequately controlled with standard therapy by self-perception, from 12 countries through physicians o...

IntroductionIntegrins are heterodimeric transmembrane proteins composed of alpha and beta subunits that mediate cell-cell and cell-extracellular matrix (ECM) interactions. Several integrins are overexpressed in human cancers and their ECM recognition motif, arginine-glycine-aspartate (RGD), is being utilized for tumour imaging and targeting.AimTo explore the expression and function of RGD-binding integrins in...

Cow’s milk remains a key source of iodine in the UK. However, there are concerns around the environmental impact of methane emissions from dairy cattle. Initial work suggests that adding certain seaweed species to the diet of cows can reduce enteric methane emissions and may increase the content of certain minerals such as iodine in milk. Little is known about the simultaneous effect of this feeding practice on milk organoleptic characteristics. This study investigates th...

Background: GI neuroendocrine tumors express somatostatin (SSTR) receptors, and the radioloabeled SSTR analog Lu-177-DOTATATE is an FDA-approved systemic treatment for those with metastatic disease. Olaparib is a poly (ADP-ribose) polymerase inhibitor (PARPi) which inhibits cells from repairing damaged DNA, especially single-stranded DNA breaks caused by beta particle emissions from the radioactive decay of Lu-177. We report the first results of a phase 1/2 study evaluating th...

Background: Metastatic GI Neuroendocrine Tumors (GI-NET) and pheochromocytoma/paraganglioma (PPGL) are are tumors which overexpresses somatostatin receptors (SSTR) and can be treated with targeted radioligand therapy (RLT) such as Lu-177-DOTATATE. However, despite demonstrated clinical efficacy at stabilizing tumor growth, durable response is very rare and almost all patients inevitably progresses at some time after treatment. Good systemic therapy options after beta-emiting R...

Background: To evaluate and compare the diagnostic performance of 68Ga-DOTATATE PET/CT to 18F-FDG PET/CT, CT of neck, chest, abdomen and pelvis (CT), and MRI of cervical, thoracic, and lumbar spine (MRI spine), for the detection of spinal bone metastases in metastatic pheochromocytoma and/or paraganglioma (PPGL).Methods: Between 2014 and 2019, 41 consecutive metastatic PPGL patients (19 females; mean age, 43 years) underwent 68...

Introduction: Growth hormone (GH) replacement therapy is safe and confers significant benefits in body composition, bone health, cardiometabolic risk factors, and quality of life in adults with GH deficiency. However, longer term safety and efficacy data are limited by the lack of consistency in data collection between studies. The study aim was to develop a simple global register by standardising and developing a minimum data set (MDS) to facilitate international collection o...
