1. Oscillatory Signaling and Insulin Secretion from Single ß-cells
Abstract : cAMP and Ca2+ are key regulators of exocytosis in many cells, including insulin-secreting pancreatic β-cells. Glucose-stimulated insulin secretion from β-cells is pulsatile and driven by oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), but little is known about the kinetics of cAMP signaling and the mechanisms of cAMP action.

2. Regulation of E-cadherin mediated adhesion in thyroid epithelial cells
Abstract : Cell adhesion is one of multicellular organisms most fundamental features. Cells connect to each other by transmembrane proteins arranged in junction complexes. READ MORE

3. Epac2 signaling at the β-cell plasma membrane
Abstract : Secretion of appropriate amounts of insulin from pancreatic β-cells is crucial for glucose homeostasis. The β-cells release insulin in response to glucose and other nutrients, hormones and neurotransmitters, which trigger intracellular signaling cascades, that result in exocytotic fusion of insulin-containing vesicles with the plasma membrane.

4. The calcitonin gene family of peptides : receptor expression and effects on bone cells
Abstract : The calcitonin gene family of peptides consists of calcitonin (CT), two calcitonin gene related peptides (α-CGRP, β-CGRP), adrenomedullin (ADM), amylin (AMY), three calcitonin receptor activating peptides (CRSP1-3) and intermedin/adrenomedullin2 (IMD). These peptides bind to one of two G protein -coupled receptors, the calcitonin receptor (CTR) or the calcitonin receptor-like receptor (CRLR). READ MORE

5. The role of phosphodiesterase 3B in energy metabolism
Abstract : Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. READ MORE
