產品詳情

  • 產品描述：
    豬生饑餓激素(GHRL)酶聯免疫試劑盒（CSB-E09437p）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的GHRL含量。GHRL即胃饑餓素，是胃分泌的一種肽。它能調節(jié)食欲和能量穩(wěn)態(tài)，與肥胖、糖尿病等代謝疾病相關。研究機制主要圍繞其與受體的結合，通過信號傳導調節(jié)神經內分泌，影響進食行為和代謝過程，為相關疾病治療提供潛在靶點。試劑盒檢測范圍為62.5 pg/mL-4000 pg/mL，本試劑盒適用于科研場景中GHRL相關基礎研究，例如探索營養(yǎng)干預、代謝性疾病模型或生理周期變化對GHRL表達的影響，滿足能量代謝機制、內分泌調控通路等領域的科研需求。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR). Induces the release of growth hormone from the pituitary. Has an appetite-stimulating effect, induces adiposity and stimulates gastric acid secretion. Involved in growth regulation.; Obestatin may be the ligand for GPR39. May have an appetite-reducing effect resulting in decreased food intake. May reduce gastric emptying activity and jejunal motility.
  • 基因功能參考文獻：
    1. These expression data may indicate that factors other than ghrelin and leptin are more involved in the regulation of feed intake in pigs apparently acclimated to heat stress. PMID: 27264891
    2. slc30A8 colocalizes with ghrelin and motilin in the gastrointestinal tract of pigs PMID: 26388512
    3. Studied an alternative vascular approach to the modulation of gastric ghrelin levels.. PMID: 25294792
    4. Obestatin enhances proliferation and differentiation of preadipocytes promoting PPARgamma and C/EBPa expression, and inhibiting preadipocyte apoptosis by decreasing expression of Caspase-3, Caspase-7 and Caspase-9. PMID: 24534601
    5. The expression of ghrelin in the digestive tract of low birth weight and normal weight piglets is reported. PMID: 24237675
    6. Data suggest that a dietary factor (here, high levels of dietary copper) is able to up-regulate expression of ghrelin in the fundic gland of growing pigs; the diets tested in this study also increase feed intake and promote weight gain. PMID: 22911428
    7. Ghrelin immunolocalization in the gastrointestinal tract of pigs at different ages were studied and it was concluded that gastric ghrelin expression is not related merely to age but could also potentially be influenced by food intake. PMID: 22281862
    8. BsrI polymorphism at the ghrelin gene locus is potentially associated with carcass and meat quality traits. PMID: 21669497
    9. Plasma concentrations of ghrelin were greater before feeding and decreased after feeding in pigs fed once per day; there was no consistent pattern to ghrelin secretion in the ad libitum fed group. PMID: 20399063
    10. glucose output by primary porcine hepatocytes in suspension culture, after incubation with acylated ghrelin (AG), unacylated ghrelin (UAG), and hexarelin (HEX). PMID: 15536157
    11. Immunization against ghrelin was associated with increased antibody titers, decreased voluntary food consumption, and decreased body weight gain by pigs. PMID: 16793235
    12. ghrelin mRNA expression is up-regulated 10 days after weaning in the gastric fundus of piglets, coinciding with the increase of H(+)-K(+)-ATPase mRNA expression and activity PMID: 16920167
    13. growth hormone stimulated both ghrelin synthesis and secretion in the ovarian follicles PMID: 17951088
    14. Ghrelin requires activation of the NOS/NO route, and its subsequent GC/cGMP signal transduction pathway, as necessary steps to induce GH secretion from somatotrophs. PMID: 18208548
    15. Expression of ghrelin mRNA is affected by estrus in the hypothalamus, pituitary gland and ovary. PMID: 18295988
    16. circulating total plasma ghrelin concentrations in the pig appear to be influenced by chronic changes in energy balance rather than the feeding pattern per se. PMID: 18434347
    17. provides novel evidence that ghrelin has a modulatory effect in the ovary PMID: 19212011
