Effect of in ovo ghrelin administration on subsequent serum insulin and glucose levels in newly-hatched chicks
chicken embryo ghrelin in ovo injection insulin
2015/6/9
Ghrelin is a regulatory peptide in glucose homeostasis in animal species. Its effect in the avian embryo is unclear. The aim of this study was to investigate the effects of in ovo ghrelin administrati...
为了解牛卵丘-卵母细胞复合体（COCs）体外成熟过程中Ghrelin对卵丘细胞增殖的可能调节及其与促卵泡素（Follicle-stimulating hormone，FSH）在卵丘细胞增殖过程中可能的调控关系，本研究运用实时定量RT-PCR技术首先检测了体外不同成熟时间（0 、8 、16和24 h）牛卵丘细胞中Ghrelin mRNA的相对表达差异，然后在体外成熟8 h，探讨了FSH与FSH受体结...
除胃饥饿素（Ghrelin）外，Ghrelin基因还能衍生出多种具有活性的产物。本文对Ghrelin基因衍生肽进行了介绍，并对2种主要的产物去酰化胃饥饿素（Des-acyl ghrelin）和肥胖抑制素（Obestatin）的分布、主要功能及其分泌调节等内容进行了综述，旨在为开展其在动物生产领域中的研究提供理论基础。
Ghrelin免疫阳性细胞在山羊胃肠道的发育性变化
Ghrelin 济宁青山羊 胃肠道 免疫组化
2013/12/2
为探究Ghrelin免疫阳性细胞山羊胃肠道的定位分布、形态特征与发育性变化，选用0、30、60、90、120、150和180日龄雌性济宁青山羊，按试验要求取材后进行免疫组织化学方法染色。结果显示，Ghrelin免疫阳性细胞主要分布在黏膜上皮、腺体和固有层，有“闭合型”和“开放型”2种类型。2种类型细胞在皱胃、十二指肠、空肠、回肠、盲肠和结肠均有分布，但未在瘤胃、网胃、瓣胃和直肠中检出。Ghreli...
旨在研究Ghrelin对产蛋鸡等级前卵泡发育的调节作用。通过RTPCR方法检测卵泡Ghrelin受体（GHSR）的表达情况，采用组织学和免疫组化方法探讨Ghrelin和促卵泡素（FSH）单独或联合处理对鸡等级前卵泡形态学的变化以及层粘连蛋白（LN）和缝隙连接蛋白43（Cx43）的标记率。结果表明，GHSR在颗粒层和膜层上均有表达，其表达量随着卵泡的发育分别至大白卵泡（LWF）和小黄卵泡（SYF）...
Intracerebroventricular Injection of Ghrelin Induces Sleep-Like Behavior in Neonatal Chicks
ghrelin intracerebroventricular sleep-like behavior chick
2009/8/3
Ghrelin, a novel growth hormone (GH)-releasing acylated peptide, is recently isolated from rat stomach. This peptide stimulates the release of GH from the anterior pituitary through the GH secretagogu...
Ghrelin in Birds:Its Structure,Distribution and Function
birds function gene expression ghrelin structure
2009/7/30
Feeding and somatic growth are closely related to each other,and are strictly governed by several endocrine and neuroendocrine systems in animals. Endocrine control of growth is an important subject i...
The aim of this study was to determine whether ghrelin was present in the internal contents of eggs. Ghrelin in the internal contents of fertilized eggs incubated for 0 to 5 days was measured by a t...
Effects of Exogenous Ghrelin on the Behaviors and Performance of Weanling Piglets
Ghrelin Behavior Drinking Piglet Stress Weanling
2016/4/27
The objective of this study was to evaluate the effect of exogenous ghrelin on the behaviors, weight gain, and feed intakes of weanling piglets. A total of 25 pairs of Duroc??Landrace??Large White pig...
