摘要:

为探究鹅肥肝形成的分子机制,利用4D-DIA定量蛋白质组学技术分析了3个不同填饲阶段的朗德鹅肝脏样品。本研究选取同批次体况相近的70日龄朗德鹅,分别在填饲前期(7 d)、填饲中期(16 d)、填饲后期(25 d)随机选取3只鹅屠宰,采集肝大叶肝尖组织样,用于4D-DIA定量蛋白组学分析,共3组,每组3个生物学重复。结果:1)在3个不同填饲阶段的朗德鹅肝脏共鉴定出5 208个蛋白。2)通过主成分分析发现,3个填饲阶段鹅肝脏蛋白谱存在明显差异,填饲前期与中期鉴定出449个差异蛋白,中期与后期鉴定出303个差异蛋白。3)通过代谢通路分析发现,鹅肥肝形成过程中发生显著变化的通路主要涉及类固醇激素生物合成、脂肪细胞因子信号通路、氨基糖和核苷酸糖代谢、半胱氨酸和蛋氨酸代谢、花生四烯酸代谢、氨基酸的生物合成等,并利用荧光定量PCR技术筛选了关键差异基因ADIPOQPASK。填饲导致鹅肝脏蛋白组谱发生显著变化,与类固醇激素生物合成、脂肪细胞因子信号通路等相关的蛋白可能参与到了鹅肥肝形成的分子调控。

Abstract:

The study aimed to explore the molecular mechanism of foie gras formation, liver samples of Landes geese at 3 different feeding stages were analyzed by 4D-DIA quantitative proteomics. The 70-day-old Landes geese of the same batch with similar body condition were randomly selected and slaughtered at the early stage (7 d), middle stage (16 d) and final stage (25 d), 3 in each stage, respectively. The liver lobe and liver apex tissue samples were collected for 4D-DIA quantitative proteomic analysis. There were 3 groups with 3 biological replicates each. Result: 1) A total of 5 208 proteins were identified by comparison of the Landes geese liver at three different feeding stages. 2) Principal component analysis revealed significant differences in liver protein profiles across the 3 over-feeding stages, with 449 differential proteins identified in the comparison of early stage vs. middle stage, and 303 differential proteins identified in the comparison of middle stage vs. final stage. 3) Through pathway analysis of the differential metabolites, the enriched pathways were observed to be mainly involved in steroid hormone biosynthesis, ADIPOQ signaling pathway, amino sugar and nucleotide sugar metabolism, cysteine and methionine metabolism, arachidonic acid metabolism, and amino acid biosynthesis. The key differential genes ADIPOQ and PASK were identified based on RT-qPCR. The proteomic profile of liver of geese was significantly changed after over-feeding. The proteins related to steroid hormone biosynthesis and adipocytokine signaling pathway may be involved in the molecular regulation of foie gras formation.

Key words: foie gras, 4D-DIA quantitative proteomics, lipid metabolism, differential protein, molecular regulation mechanism
