The GHR gene expression in lung tissue at 120 days of age was extremely higher than those at other days of age( P<0.01). The GHR gene expressions in intestine tissue at 45 and 120 days of age were extremely higher than those at other days of age(P<0.01), but no significant difference was observed between 45 and 120 days of age(P>0.05). The GHR gene expression in kidney tissue at 150 days of age was significantly higher than those at other days of age( P<0.05).The GHR gene expression in skin tissue was extremely higher than that those at other days of age( P<0.01). The GHR gene expressions in intestinal tissue at 45 and 120 days of age were extremely higher than those in other tissues(P<0.01). The GHR gene expressions in skin tissue at 90 days of age was extremely higher than those in other tissues(P<0.01). The GHR gene expressions in intestine, spleen and kidney tissues at 150 days of age were extremely higher than those in other tissues(P<0.01). The GHR gene expressions in spleen tissue at 180 days of age was extremely higher than those in other tissues(P<0.01).[Conclusion] The expression of GHR gene in mink showed obvious spatio-temporal specificity.展开更多

The results showed that two SNPs were found at position 209 （T/C） and position 533 （C/A） of the 10^th exon of GHR gene in the two mink populations.展开更多
为了筛选与繁殖性能相关的显著差异表达蛋白及信号通路,试验采用TMT(tandem mass tag)标记蛋白定量技术与生物信息学分析方法,对高产(产仔数在11只以上)与低产(产仔数在7只以下)乌苏里貉卵巢组织进行差异表达蛋白筛选,GO功能注释、KEGG...为了筛选与繁殖性能相关的显著差异表达蛋白及信号通路,试验采用TMT(tandem mass tag)标记蛋白定量技术与生物信息学分析方法,对高产(产仔数在11只以上)与低产(产仔数在7只以下)乌苏里貉卵巢组织进行差异表达蛋白筛选,GO功能注释、KEGG信号通路富集分析。结果表明:在乌苏里貉卵巢组织中共鉴定到4915种蛋白,其中372种为显著差异表达蛋白(P≤0.05,差异倍数≥1.2或≤0.83),上调307种,下调65种。差异表达蛋白主要参与了羧酸代谢过程、胞内氨基酸代谢过程、转录起始、胞内脂代谢过程、磷脂代谢过程、GTP生物合成过程、UTP生物合成过程、CTP生物合成过程等生物学过程,主要参与了组氨酸代谢、氨酰-tRNA生物合成、N-聚糖生物合成、β-丙氨酸新陈代谢、PI3K-Akt信号通路、mTOR信号通路等16条信号通路;有11种差异表达蛋白与卵泡发育和排卵相关。蛋白网络互作分析获得10种核心蛋白,参与了蛋白折叠和蛋白合成。说明试验筛选到的显著差异表达蛋白可能与乌苏里貉的产仔数相关。展开更多
