Expression of NK1 receptor at the protein and mRNA level in the porcine female reproductive system
2015
Bukowski, R.
The presence and distribution of substance P (SP) receptor NK1 was studied in the ovary, the oviduct and the uterus (uterine horn and cervix) of the domestic pig using the methods of molecular biology (RT-PCR and immunoblot) and immunohistochemistry.The expression of NK1 receptor at mRNA level was confirmed with RT-PCR in all the studied parts of the porcine female reproductive system by the presence of 525 bp PCR product and at the protein level by the detection of 46 kDa protein band in immunoblot. Immunohistochemical staining revealed the cellular distribution of NK1 receptor protein. In the ovary NKI receptor was present in the wall of arterial blood vessels, as well as in ovarian follicles of different stages of development. In the tubular organs the NK1 receptor immunohistochemical stainings were observed in the wall of the arterial blood vessels, in the muscular membrane, as well as in the mucosal epithelium.The study confirmed the presence of NK1 receptor in the tissues of the porcine female reproductive tract which clearly points to the possibility that SP can influence porcine ovary, oviduct and uterus.
