为探明柯乐猪血液免疫细胞的基因表达是否受甲基化调控,应用甲基化敏感扩增多态性技术(MSAP)和酶联免疫吸附测试技术(ELISA)对柯乐猪与大白猪血液基因组 DNA 的甲基化水平、血清中的细胞因子浓度进行检测,分析柯乐猪与大白猪在甲基化水平、细胞因子浓度方面的差异及其相关关系。结果表明:柯乐猪基因组总甲基化水平为32.38%,与大白猪接近(P >0.05);IL-2、IL-4、IL-6和 IL-10浓度分别为(302.37±125.72)pg/mL、(88.71±32.05)pg/mL、(219.01±30.42)pg/mL 和(116.95±30.24)pg/mL,其中 IL-6和 IL-10分别极显著、显著低于大白猪;IFN-α、IFN-γ分别为(211.09±76.08)pg/mL和(57.18±14.21)pg/mL,分别极显著、显著高于大白猪。柯乐猪基因组的全甲基化水平与 IFN-γ浓度间呈弱负相关关系(ρ=-0.256)。说明,血液免疫细胞的基因表达可能受甲基化的调控,且与柯乐猪的抗病力强有关。
為探明柯樂豬血液免疫細胞的基因錶達是否受甲基化調控,應用甲基化敏感擴增多態性技術(MSAP)和酶聯免疫吸附測試技術(ELISA)對柯樂豬與大白豬血液基因組 DNA 的甲基化水平、血清中的細胞因子濃度進行檢測,分析柯樂豬與大白豬在甲基化水平、細胞因子濃度方麵的差異及其相關關繫。結果錶明:柯樂豬基因組總甲基化水平為32.38%,與大白豬接近(P >0.05);IL-2、IL-4、IL-6和 IL-10濃度分彆為(302.37±125.72)pg/mL、(88.71±32.05)pg/mL、(219.01±30.42)pg/mL 和(116.95±30.24)pg/mL,其中 IL-6和 IL-10分彆極顯著、顯著低于大白豬;IFN-α、IFN-γ分彆為(211.09±76.08)pg/mL和(57.18±14.21)pg/mL,分彆極顯著、顯著高于大白豬。柯樂豬基因組的全甲基化水平與 IFN-γ濃度間呈弱負相關關繫(ρ=-0.256)。說明,血液免疫細胞的基因錶達可能受甲基化的調控,且與柯樂豬的抗病力彊有關。

The methylation level of genomic DNA and cytokines concentration in serum of Kele and Yorkshine pigs were detected by MSAP and ELISA and the correlation between methylation level and cytokines concentration was analyzed to explore the effect of methylation regulation on genetic expression of blood immune cells of Kele pig.The genomic methylation level of Kele pig is 32.38% and is similar to Yorkshine pig(P >0.05).The concentration of IL-2,IL-4,IL-6 and IL-10 is (302.37±125.72)pg/mL, (88.71±32.05)pg/mL,(219.01±30.42)pg/mL and (116.95±30.24)pg/mL respectively,of which,IL-6 and IL-10 concentration is very significantly and significantly lower than Yorkshine pig separately.The concentration of IFN-αand IFN-γ is (211.09±76.08)pg/mL and 57.18±14.21)pg/mL,very significantly and significantly higher than Yorkshine pig separately.There is a weak negative correlation between genomic methylation level and IFN-γ concentration in Kele pig (ρ= -0.256),which indicates that gene expression of blood immune cells may be regulated by methylation and be related to strong disease resistance of Kele pig.
