Outline of Final Research Achievements |
In this study, it was revealed the following three points using smooth muscle cells having both TRIC channel subtypes and Ca2+ release channels including ryanodine cereptor (RyR) and inositol-1,4,5-trisphosphate receptor (IP3R). 1) Overexpression of TRIC-A enhanced hyperpolarization signaling which evoked by Ca2+ spark, and showed hypotension induced by constitutively vascular relaxation. 2) It was suggested that TRIC-A expression level in vascular smooth muscle cells controlled blood pressure. 3) It was suggested that TRIC-A expression level in vascular smooth muscle cells also affected the amount of Ca2+ contents in the endo/sarcoplasmic reticulum which distributed RyR and/or IP3R.
