Cardiac hypertrophy and impaired relaxation in transgenic mice overexpressing triadin 1.
Triadin 1 is a major transmembrane protein in cardiac junctional sarcoplasmic reticulum (SR), which forms a quaternary complex with the ryanodine receptor (Ca(2+) release channel), junctin, and calsequestrin. To better understand the role of triadin 1 in excitation-contraction coupling in the heart, we generated transgenic mice with targeted overexpression of triadin 1 to mouse atrium and ventr...
متن کاملmpaired relaxation in transgenic mice overexpressing junctin
Objective: Junctin is a major transmembrane protein in cardiac junctional sarcoplasmic reticulum, which forms a quaternary complex 21 with the ryanodine receptor (Ca release channel), triadin, and calsequestrin. Methods: To better understand the role of junctin in excitation–contraction coupling in the heart, we generated transgenic mice with targeted overexpression of junctin to mouse heart, u...
متن کاملCraniosynostosis in transgenic mice overexpressing Nell-1.
Previously, we reported NELL-1 as a novel molecule overexpressed during premature cranial suture closure in patients with craniosynostosis (CS), one of the most common congenital craniofacial deformities. Here we describe the creation and analysis of transgenic mice overexpressing Nell-1. Nell-1 transgenic animals exhibited CS-like phenotypes that ranged from simple to compound synostoses. Hist...
متن کاملCardiac remodeling and atrial fibrillation in transgenic mice overexpressing junctin.
Junctin is a 26-kDa integral membrane protein, colocalized with the ryanodine receptor (RyR) and calsequestrin at the junctional sarcoplasmic reticulum (SR) membrane in cardiac and skeletal muscles. To elucidate the functional role of junctin in heart, transgenic (TG) mice overexpressing canine junctin (24-29 folds) under the control of mouse a-myosin heavy chain promoter were generated. Overex...
متن کاملCalcium Signaling in Transgenic Mice Overexpressing Cardiac Na+-Ca2+ Exchanger
We have produced transgenic mice which overexpress cardiac Na(+)-Ca2+ exchange activity. Overexpression has been assessed by Western blot, Northern blot, and immunofluorescence. Functional overexpression was analyzed using membrane vesicles and isolated ventricular myocytes. In whole cell clamped myocytes dialyzed with 0.1-0.2 mM Fura-2, the magnitude of ICa and Ca2+i-transient triggered by ICa...
