Abstract

Abstract:

To investigate the function of soluble guanylate cyclase (sGC) in alpaca skin and coat color regulation, differential expression of sGC in skin of brown versus white alpacas was examined using quantitative real-time PCR(qRT-PCR), Western blotting and immunohistochemistry．Expression of sGC mRNA was lower (0.16 fold) in skin samples from brown alpacas relative to expression in skin of white alpacas with significant difference (P<0.01). Using a rabbit polyclonal sGC antibody, an immune reactive band corresponding to sGC was detected by Western blotting analysis in skin samples from white and brown alpacas, showing a weaker signal detected in the samples from brown alpacas with significant difference (P<0.01). The results of immunohistochemistry revealed that sGC was localized in the cytoplasm and intercellular substance of upper hair papilla in hair follicles of alpacas with white hair color, but was localized in ytoplasm and intercellular substance of lower hair bulb and outer root sheath cells in hair follicles of alpacas with brown hair color. Observed differential expression and localization of sGC in skin of white versus brown alpacas suggests a potential role in hair color regulation.
