Cellular Ca2+ signals have been proposed to activate signal for hormone secretion. In pancreatic β cell which produce insulin, Ca2+ signals have been known contributing insulin secretion. Prior to conduct this study, we confirmed Calbindin-D9k (CaBP-9k) which responsible for regulation of the distribution of free calcium in the cytoplasm. We confirmed Insulin-secreting β cell express CaBP-9k and assumed that CaBP-9k play a certain role in β...

Introduction: Hypoxia is involved with various physiological activities from glucose metabolism to tumor suppression. Hypoxia-inducible factor (HIF) is known as master regulator of oxygen homeostasis that triggers more than 1,000 related gene expressions. When hypoxia occurs, HIF1a protein is stabilized and starts transcription. Mucin1 mediates the stabilization of HIF1a in a cytoplasm. In addition, cytoplasmic domain of mucin1 and HIf1a form a transcriptional complex at glyco...

It has been proposed that cellular Ca2+ signals activate hormone secretion. In pancreatic β cells, which produce insulin, Ca2+ signals have been known to contribute to insulin secretion. In previous study, demonstrated that endocrine disrupting chemicals (EDCs) such as bisphenol A (BPA) and Octylphenol (OP) could cause increase in insulin level and insulin transcription factors. But in regulations of plasma glucose level were not decreased as much as...

Introduction: Phthalates are chemicals used to improve the plasticity of industrial polymers and used in commercial products such as toys, paints, packaging materials, medicals devices and personal care items. Phthalates, endocrine disrupting chemicals, have been documented to cause adverse effects to the human health such as breast cancer in female, reduced uroogenital distance and changed the expression of steroidogenesis and folliculogenessis. In this study, we investigated...

It has been proposed that cellular Ca2+ signals activate hormone secretion. In pancreatic β cells, which produce insulin, Ca2+ signals have been known to contribute to insulin secretion. Prior to this study, we confirmed that Calbindin-D9k (CaBP-9k) was responsible for regulation of the distribution of free calcium in the cytoplasm. We also confirmed that insulin-secreting β cells express CaBP-9k, and assumed that CaBP-9k play a role in β c...

Calcium ion is important for physiological functions in all tissues and organs, and is essential for many vital functions. Calcium in lumen is absorbed to cytosol, and Calbindin-D9k binds calcium. It can remove calcium to extracellular through PMCA1 and NCX1. However, in the rat esophagus, the calcium related gene regulations and localizations were not well documented. We evaluated calcium related genes including Calbindin-D9k, PMCA1, and NCX1. Immature rats were daily treated...

Cellular Ca2+ signals have been proposed to activate signal for hormone secretion. In pancreatic β cell which produce insulin, Ca2+ signals have been known contributing insulin secretion. Prior to conduct this study, we confirmed calbindin-D9k (CaBP-9k) which responsible for regulation of the distribution offree calcium in the cytoplasm. Hypoxic condition induces endoplasmic reticulum(ER) stress, increase both insulin signaling and insulin resistance. Byexposing hypoxia, ...
