In Drosophila, the glial cells missing (gcm) gene encodes a transcription factor that controls the determination of glial versus neuronal fate. In gcm mutants, presumptive glial cells are transformed into neurons and, conversely, when gcm is ectopically misexpressed, presumptive neurons become glia. Although gcm is thought to initiate glial cell development(More)
Severe systemic infections induce ubiquitous calcitonin (CALC) gene expression with release of calcitonin peptides, namely procalcitonin, calcitonin gene-related peptide and adrenomedullin. Using an in vitro model for bacterial infection, we tested the hypothesis that intracellular calcium concentration ([Ca(2+)](i)) is elevated after lipopolysaccharide(More)
OBJECTIVE To study the effects of metformin on lipolysis and hormone sensitive lipase (HSL) phosphorylation in human adipocytes treated with lipolytic and inflammatory agents. METHODS Lipolysis and phosphorylation status of HSL were assessed in subcutaneous pre-adipocytes surgically isolated from patients and differentiated into mature adipocytes in(More)
The mechanisms of metformin effects on glucose transport and metabolism were investigated in human adipocytes. Human preadipocytes obtained from surgical biopsies were differentiated in vitro into adipocytes and the effects of metformin on glucose uptake, glucose oxidation and the involved signaling pathways were analyzed. Metformin (1mM, 24h) increased(More)
High fat diet-induced endotoxaemia triggers low-grade inflammation and lipid release from adipose tissue. This study aims to unravel the cellular mechanisms leading to the lipopolysaccharide (LPS) effects in human adipocytes. Subcutaneous pre-adipocytes surgically isolated from patients were differentiated into mature adipocytes in vitro. Lipolysis was(More)
BACKGROUND Procalcitonin has been well established as an important marker of sepsis and systemic infection. The authors evaluated the diagnostic and predictive value of calcitonin and its prohormone procalcitonin in medullary thyroid cancer. METHODS The authors systematically explored the ability of calcitonin and procalcitonin to identify medullary(More)
CONTEXT Increased plasma levels of glucose-dependent insulinotropic polypeptide (GIP), calcitonin CT gene-related peptide (CGRP)-I, and procalcitonin (Pro-CT) are associated with obesity. Adipocytes express functional GIP receptors and the CT peptides Pro-CT and CGRP-I. However, a link between GIP and CT peptides has not been studied yet. OBJECTIVE The(More)
