  • Expression of HERG in CD1 Mice Gallbladder and Its Possible Implications

    Objective To study the expressions of human ether-a-go-go related gene (HERG) in CD1 mice gallbladder and interstitial cells of Cajal (ICC) and explore their possible implications. Methods The expression of HERG protein in gallbladder tissue slices obtained from CD1 mice was detected by immunohistochemistry method. The expression of HERG mRNA in gallbladder tissue was detected by reverse transcription (RT)-PCR. The production of HERG protein was confirmed in the CD1 mice gallbladder by Western blot. Enzymatically dispersed cells were identified as ICC using the specific ICC marker c-kit antibody, and the double positive cells of c-kit and HERG were observed by laser passing confocal microscope. Results HERG was present in the CD1 mice gallbladder tissues for the yellow or buffy positive reaction. At the same time, the expression of mRNA specific for the HERG gene and production of HERG protein in the CD1 mice gallbladder tissues were indicated by RT-PCR and Western blot analysis, respectively. Using double labeling of anti-c-kit and anti-HERG, the double positive cells of c-kit and HERG were observed in the CD1 mice ICC by laser passing confocal microscope. Conclusion The study demonstrates that HERG is present in the CD1 mice gallbladder tissues and ICC, which is likely related to the pacemaking activity of ICC.
