    Background: The present study was designed to examine the influence of inositol 1,4,5-trisphosphate receptor (IP3R) and calcium calmodulin-dependent protein kinase (CaMK) on endothelin receptor regulation during organ culture in rat middle cerebral arteries (MCA). Methods: MCA segments were incubated with or without xestospongin C (XeC), an IP3R inhibitor, or KN93, a CaMKII blocker. The mRNA levels of the ETA and ETB receptors, nuclear factor of activated T cells activating protein (NFam1), CaMKII, IP3R and Downstream regulatory element antagonist modulator (DREAM) protein were determined by real-time PCR or immunohistochemistry. Contractile responses to endothelin-1 (ET-1) and sarafotoxin 6c (S6c) were studied by a sensitive myograph and the intracellular calcium levels [Ca2+]i were evaluated by the FURA-2AM. Results:..
