Genomic Variant in NK-Lysin Gene Is Associated with T Lymphocyte Subpopulations in Pigs.

ABSTRACT: As an antimicrobial peptide, NK-lysin (NKL) plays an important role in the innate immune system of organisms. In this study, 300 piglets (68 Landrace pigs, 158 Large White pigs and 74 Songliao Black pigs) were used to further explore the function of NLK gene in porcine immune system. The quantitative real-time PCR analysis detected the NKL gene's expression, and the result demonstrated that NKL mRNA was expressed in lung, spleen, stomach, kidney, liver and heart, and the expression level decreased sequentially. A single-nucleotide polymorphism (SNP, g.59070355 G > A) in intron 3 of the NKL gene was detected by PCR amplification and sequencing. The results of the Chi-square (χ2) test showed that the genotype of the SNP was consistent with the Hardy-Weinber
