Adjuvant treatment for post-menopausal women with early breast cancer (BC) includes aromatase inhibitors (AI), known to decrease bone mineral density (BMD). In this study, we investigate whether denosumab is a valid second option for patients unable to receive standard adjuvant i.v. zoledronic acid (ZA). In total, 212 patients have been evaluated after they did not receive ZA. Of those 194 were included. After evaluation by an endocrinologist, all patients were offered ZA as t...

The pathogenesis of gonadotrophin secreting pituitary tumours (gonadotrophinomas) remains poorly understood. Bone morphogenetic proteins (BMPs) are important for the control of cell proliferation and differentiation and BMP2 is essential for commitment of undifferentiated pituitary cells to the gonadotroph cell lineage. In addition, BMPs have been implicated in tumourigenesis in a variety of tissues, associated with up-regulated expression of Id (Inhibitors of differentiation)...

Adrenomedullin (AM) is a multifunctional peptide hormone which plays a significant role in vasodilation and angiogenesis, implicating it in hypertension as well as in carcinogenesis. AM exerts its effects via the Calcitonin Receptor-Like Receptor (CLR) complexed with either Receptor Activity Modifying Protein (RAMP) 2 or 3.The aim of the present study is to investigate the biological actions, functions and possible target genes of AM in immortalized Huma...

Adrenomedullin (ADM) is a multifunctional peptide which plays a significant role in vasodilation, angiogenisis and septic shock. It exerts its effects via the calcitonin receptor-like receptor (CRLR) in combination with either receptor associated protein (RAMP) 2 or 3. However the regulation of the ADM receptors is still widely unknown (1). In the present study the effects of adrenomedullin on immortalized Human Microvascular Endothelial Cells (HMECs) was investigated. Endothe...

Background: Peptide receptor radionuclide therapy (PRRT) is a promising radiation-based therapy for metastatic neuroendocrine tumors (NETs) but remains palliative. Peptidyl-prolyl cis-trans isomerase (Pin1) is an evolutionally conserved enzyme that catalyzes the cis-trans isomerization of phosphorylated serine/threonine-proline motifs of its substrates and has recently been involved in DNA double strand break (DSB) repair in BRCA-proficient breast cancer cells. Here we study w...

Bone loss in chronic autoimmune inflammatory diseases is a major clinical problem. Inflammation-mediated osteoposis (IMO) is the first animal model of generalized osteoporosis resulting from inflammation. The P2×7 receptor, an ATP-gated ion-channel, is primarily expressed on immune and bone cells. ATP is now seen as a novel inflammatory mediator, with P2×7 as main target of the pro-inflammatory activity. The P2×7-receptor has a regulatory role in bone formation ...

The calcium receptor (CASR) serves as one of the main regulators of the calcium homeostasis. CASR is expressed in among other tissues parathyroid chief cells and kidney tubule cells. It has been hypothesized that CASR gene variations are responsible for low circulating calcium levels together with hypercalciuria and thereby increased risk of kidney stones. The CASR gene polymorphism A986S has been shown associated to elevated serum calcium levels in vivo<...

Introduction: Discontinuation of GH therapy in patients with COGHD after attainment of final height has been associated with impaired somatic development, altered peak bone mass and cardiovascular risk factors. A well-managed transition of care between paediatric and adult health services can improve the clinical and social outcomes in adolescents with GHD.Objective: To assess the quality of the transfer between children and adult medical services in our...

Objective: Adjuvant chemotherapy is often indicated in patients diagnosed with early breast cancer. Weight gain is one of the observed side effects of both chemotherapy and other cancer treatments, however, the mechanism is not well-described. In this study, we aimed to assess thyroid function before- and after the course of chemotherapy for early breast cancer.Methods: This study is a 5-year prospective cohort study of patients diagnosed with early brea...

Introduction: Aromatase inhibitors, such as Letrozole or Exemestane, are often used as adjuvant treatment for post-menopausal breast cancer. However, they are known to reduce bone mineral density (BMD). Furthermore, breast cancer patients often undergo chemotherapy with drugs associated to BMD loss by themselves. Therefore, patients treated for breast cancer are subject to a considerable risk of BMD loss, and to alleviate this the treatments are normally combined with an anti-...
