A single nucleotide polymorphism of the porcine CXCL8 gene is associated with serum CXCL8 level

Figures & data

Figure 1. Relative quantification of the porcine CXCL8 mRNA level in seven different tissues. Bars represent the mean ± SE (n = 3). The values were normalised to GAPDH expression.

Table 1. Genotype frequencies and allelic frequencies of the SNP (NC_10450.4:g.69934997T > C, rs81218904) the CXCL8 gene determined by MALDI-TOFMS method in the three pig populations.

Breed	Number	Genotype frequencies			Allelic frequencies
		TT	TC	CC	T	C
Landrace	68	36	19	13	0.67	0.33
Large White	158	88	43	27	0.69	0.31
Songliao Black	74	38	17	19	0.63	0.37

Table 2. Association analysis and multiple tests of the SNP (NC_010450.4:g.69934997T > C, rs81218904) of the CXCL8 gene with the serum CXCL8 level in the three pig populations.
