Polysialic acid (PSA) and its major protein carrier, the neural cell adhesion molecule NCAM, play important roles in many nervous system functions during development and in adulthood. Here, we show that a PSA-carrying NCAM fragment is generated at the plasma

The effect of zaldaride maleate (ZAL) on intracellular Ca2+-mediated short-circuit current (Isc) response in rat colonic mucosa was investigated. The Isc response to acetylcholine was partially reduced by the neuronal blocker tetrodotoxin. The tetrodotoxin-sensitive Isc response to acetylcholine was inhibited

The effect of zaldaride, a calmodulin inhibitor, on 16,16-dimethyl prostaglandin E2 (dmPGE2)-induced intestinal ion secretion was investigated in rats. Zaldaride inhibited the dmPGE2-induced increase in water content in the colon, but not that in the small intestine. In the colonic

The steroid hormone estrogen elicits biological effects in cells by binding to and activating the estrogen receptor (ER). Estrogen binding induces a conformational change in the receptor, inducing nuclear translocation and transcriptional activation of ER. The ubiquitous Ca(2+)-binding protein calmodulin
