摘要: 从HDLBP转录本(NM_205096.2)中鉴定6个同义突变的SNPs,在欣华鸡的关联分析发现C3381T和T387C与开产日龄(AFE)和蛋重(EW)显著关联(P<0.05),表明该基因可能是蛋用性状相关的候选基因。从小白卵泡(SWF)到小黄卵泡(SYF)中,HDLBP表达水平在膜层和颗粒层中逐渐升高。在排卵前期,F3到F2的颗粒层中HDLBP mRNA水平显著下降(P<0.05)。此外,EGF、VEGF、FSH在不同颗粒细胞生长阶段对HDLBP调控具有剂量依赖性,Follistatin对HDLBP mRNA表达没有明显影响。

Abstract: 6 SNPs in the full length of HDLBP transcript were identified as a synonymous mutation in adult hens. Association between two SNPs and egg performance traits were analyzed in Xinhua E-strain chickens, which showed that they were highly significantly associated with AFE and EW (P<0.05), suggesting that it was a candidate gene related with egg production. The HDLBP mRNA in different sized follicles showed that the expression was progressively increased in follicles from undifferentiated follicles to SYFs, and maintain stable in pre-ovulatory follicle. Besides, FSH, EGF, VEGF with dosage dependent could regulate the expression of HDLBP in granulosa cells of phases, while Follistatin showed no effect.
