  • 產(chǎn)品描述：
    大鼠黃體生成素（LH）酶聯(lián)免疫試劑盒（CSB-E12654r）為競爭法ELISA試劑盒，定量檢測血清、血漿樣本中的LH含量。LH即促黃體生成素，是腺垂體分泌的糖蛋白激素。它在生殖系統(tǒng)中扮演重要角色，可刺激卵巢排卵和黃體形成，促進雄激素合成與分泌。研究表明，其水平變化與多種生殖內(nèi)分泌疾病相關(guān)，深入研究其作用機制有助于疾病診斷與治療。試劑盒檢測范圍為0.3 mlU/ml-60 mlU/ml，適用于科研領(lǐng)域探索生殖系統(tǒng)疾病模型建立、動情周期激素動態(tài)監(jiān)測、藥物干預對性腺軸的影響等研究場景。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

  • 基因功能參考文獻：
    1. Orchestrated Egr1 and Pitx1 activities depending on specific central and peripheral regulatory inputs could be responsible for physiologically variable Lhb gene promoter activation in vivo. PMID: 25258388
    2. GnRH stimulates AMPK, and AMPK inhibition suppresses GnRH-stimulated LHbeta transcription. PMID: 23518923
    3. data suggest that the molecular decision for LHbeta subunit to enter the regulated secretory pathway is a pre-Golgi event controlled by the C-terminal heptapeptide. PMID: 23734233
    4. increased LH concentration induces production of incomplete LHR transcripts in hippocampal cells and decreases immature LHR at the protein level PMID: 23678542
    5. Data suggest that LH beta subunit expression (and FSH beta subunit expression) is regulated by DUSP1 expression (specifically in response to high-frequency GnRH pulses); this effect may occur in association with MAPK3/1 phosphorylation. PMID: 21228211
    6. Complex interactions between Ahr and Esr alter Prl and luteinizing hormone (LH) synthesis by direct actions in lactotropes and gonadotropes. PMID: 21187122
    7. LHbeta promoter activity is further regulated by the orphan nuclear receptors, chicken ovalbumin upstream promoter-transcription factors (COUP-TFI and COUP-TFII). PMID: 20797425
    8. data suggest that LHbeta G1502A polymorphism may be involved in the predisposition to infertility and minimal/mild endometriosis-associated infertility, although endometriosis might be only a coincidental finding along with infertility. PMID: 20430510
    9. PACAP may be released from the anterior pituitary cells in a concentration which would be able to influence LH release not only in vitro but under in vivo conditions as well. PMID: 12409218
    10. These results suggest that GnRH directly regulates LH secretion as well as LHbeta-subunit synthesis, and that LH2 cells are a useful model for the study of LH secretion induced by several secretagogues. PMID: 12940464
    11. androgens acting directly on the pituitary increase FSH-beta and decrease LH-beta transcription PMID: 14512439
    12. identify a second functional Pitx1 region spanning positions -73 to -52 in the LHbeta gene promoter PMID: 16087728
    13. JNK regulates both LHbeta and FSHbeta transcription in a differential manner. PMID: 17932215
    14. LHbeta, FSHbeta and the common alpha-subunit mRNA's were detected in intact follicles, theca cells, corpora lutea and in meiotically competent and incompetent oocytes. PMID: 18248883
    15. the carboxyl-terminal sequence in the lutropin beta subunit contributes to the sorting of lutropin to the regulated pathway PMID: 18292086
    16. In the 14-day-old rat pituitary, the majority of GHRH target cells are cells expressing LH beta mRNA alone or in combination with GH and/or POMC mRNA. PMID: 18363807
    17. Results demonstrate that degradation via the proteasome is vital to GnRH-stimulated LHbeta expression, and this occurs in part by allowing proper transcription factor associations with the LHbeta promoter. PMID: 19095772
    18. Lhb gene transcription in rat pituitary requires GnRH-induced early growth response 1 gene expression, which is mediated by MAPK8/9 and MAPK1/3. PMID: 19710510
