We also showed that CF6 increases the gene expression related to CHF. To investigate the role of CF6 in the genesis of CHF, we generated CF6-overexpressing transgenic( TG) mice, and characterized the phenotype. DNA fragment consisting of human elongation factor 1α promoter, and human calcitonin/CF6 fused gene was injected into the embryo of C57BL/6J mouse, and homozygous TG mice were generated. In TG mice, CF6 gene was overexpressed by two fold in overall tissues compared with wild type( WT) mice. Under normal salt diet, blood pressure, heart rate, and the expression of energy metabolism-related genes were similar between TG and WT mice. When the mice were fed with 8% -salt diet for 35 weeks, the mortality of TG mice was higher than that of WT mice( survival rate; 50% in TG versus 92% in WT, p<0.05 by log-rank test). This preliminary report indicates that further examination, especially analysis of the cardiac function, is needed to clarify the cause of high mortality of TG mice under high salt intake., 弘前医学. 60(1/2/3/4), 2009, p.18-26}, pages = {18--26}, title = {Generation and Characterization of Coupling Factor 6-Overexpressing Transgenic Mice}, volume = {60}, year = {2009} }
