Abstract :
Distribution and expression of the 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) in different
breeds and tissues of pigs were studied by means of immunohistochemical and RT-PCR methods.
Three Huai and three Landrace pigs each were individually housed at the Fujian Shanghang Huai
pig breeding farm under similar feeding conditions. Pigs were humanely slaughtered at saleable
weight and samples of kidney, liver and skeletal muscle were collected for expression analyses.
mRNA expressions in liver, muscle and kidney of Huai pigs both occurred higher than
expression found in the Landrace. Positive staining of HMGR protein was revealed in the three
tissues considered. The HMGR protein expression level was not significant statistically in liver,
muscle and kidney across two breeds, but the amount of Huai pig HMGR protein expressed in
three tissues was higher than that of the Landrace. The level of HMGR protein expression in liver
was higher than in the muscle and renal tissues (
0.05). The results demonstrate that
expression in pigs may depend on tissue and species.
