Abstract:

随机选取0、3、20、30、90、120和180日龄二花脸公猪和大白公猪各4头,用相对定量RT-PCR法研究睾丸组织中生长激素受体(GHR)基因表达的发育性变化。结果表明,二花脸猪与大白猪睾丸GHRmRNA表达的发育模式不同,二花脸猪GHRmRNA相对表达量从0到30日龄逐渐上升,在90和120日龄呈阶段性降低(P<0.05),之后在180日龄又再次上调;大白猪GHRmRNA相对表达量在出生当日最高,3日龄显著下降(P<0.05),随后直至180日龄维持在较低水平并相对恒定。总的来说,二花脸猪睾丸GHRmRNA相对表达量显著高于大白猪(P<0.05)。提示不同品种猪睾丸GHRmRNA表达具有特定的发育模式,并可能与性成熟的早晚有关。
