Abstract
Imprinted genes play significant roles in the regulation of fetal growth and development, function of the placenta, and maternal nurturing behaviour in mammals. At present, few imprinted genes have been reported in pigs compared to human and mouse. In order to increase understanding of imprinted genes in swine, a polymorphism-based approach was used to assess the imprinting status of three porcine genes in 12 tissue types, obtained from F1 pigs of reciprocal crosses between Rongchang and Landrace pure breeds. In contrast to human and mouse homologues, porcine PPP1R9A was not imprinted, and was found to be expressed in all tissues examined. The expression of porcine NAP1L5 was detected in pituitary, liver, spleen, lung, kidney, stomach, small intestine, skeletal muscle, fat, ovary, and uterus, but undetectable in heart. Furthermore, porcine NAP1L5 was paternally expressed in the tissues where it's expression was observed. For PEG3, pigs expressed the paternal allele in skeletal muscle, liver, spleen, kidney, and uterus, but biallele in heart, lung, fat, stomach, small intestine, and ovary. Our data indicate that tissue distribution of the three gene differs among mammals, and the imprinting of NAP1L5 and PEG3 is well conserved.
