Introduction: Placenta has many essential roles to maintain pregnancy and homeostasis. Calcium transport and its regulation are also important for vital roles of placenta. In general, calcium transport is regulated by active transcellular and passive paracellular pathways. Transient receptor potential cation channel subfamily V member 5/6 (TRPV5/6), calbindin-D9k (CaBP-9k), calbindin-D28k (CaBP-28k), and Na+/Ca2+ exchanger (NCX1) are involved in the transcellular pathway. Para...

Introduction: Calcium transport is regulated by active transcellular and passive paracellular pathways which are responsible for calcium (re)absorption in the intestine and kidney. The activity of passive transport is determined by the permeability of tight junction. In general, the permeability of tight junction is inversely proportional with the expression of tight junction genes. Claudin and occludin among the tight junction genes are concerned directly with permeability of...
