產品詳情

  • 產品描述：
    大鼠色氨酸羥化酶(TPH)酶聯免疫試劑盒（CSB-E13984r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的TPH1含量。TPH1（色氨酸羥化酶 1）是一種重要靶點。它主要參與血清素合成，在調節情緒、睡眠、食欲等生理過程中發揮關鍵作用。研究聚焦于其在神經精神疾病如抑郁癥、焦慮癥中的機制，旨在通過調控 TPH1 活性來開發新的治療手段。試劑盒檢測范圍為37.5 pg/mL-2400 pg/mL，用于探索5 - 羥色胺相關信號通路、構建情緒障礙動物模型、分析代謝調控機制或評估藥物對神經遞質合成的影響等科研場景；助力科研人員深入解析其在生理及病理狀態下的生物學功能本品僅用于科研，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：
    Oxidizes L-tryptophan to 5-hydroxy-l-tryptophan in the rate-determining step of serotonin biosynthesis.
  • 基因功能參考文獻：
    1. Ursolic acid derivatives targeted to tryptophan hydroxylase 1 prevented bone loss by suppressing serotonin biosynthesis without estrogenic side-effects in ovariectomized rats. PMID: 25930119
    2. there exists possible interrelation between tyrosine hydroxylase and TPH gene expression and epigenetic histone acetylation in chronic unpredictable stress-induced depressive rats, which at least partly contributes to the etiology of depression. PMID: 24495952
    3. An increased expression of TPH1 in the dorsal raphe nucleus may be the primary mechanism to explain the chronic increase in the brain synthesis of 5-HT in these in utero malnourished rats. PMID: 22819790
    4. Transfection of VMAT-1 and TPH-1 induced vesicular storage of serotonin which is triggered release upon cooling and has protective effects against hypothermia. PMID: 22253933
    5. An adjacent GC-rich cis -acting sequence cooperates with the inverted CCAAT box for full activation of basal transcription; both elements are essential for full cAMP response. In pinealocytes, NF-Y and Sp1 bind the inverted CCAAT box and GC-rich-region PMID: 12065627
    6. regulation of rat tryptophan hydroxylase gene expression by stress involves 5' untranslated region PMID: 12153488
    7. TPH1 mRNA expression was 105-fold more abundant in rat pineal than TPH2; TPH2 expression within the gland showed no significant variation with time of day and was very low. PMID: 12911638
    8. This study reveals adrenal glucocorticoid-independent induction of tryptophan hydroxylase gene expression in raphe nuclei in response to immobilization stress. PMID: 14744469
    9. TPH2 mRNA is expressed in raphe, in a pattern overlapping the histologically defined raphe nuclei. In sharp contrast, TPH1 (the previously known TPH) is expressed predominantly in pineal gland. PMID: 14960297
    10. Tph1 and Tph2 transcripts showed robust diurnal rhythms of abundance, with highest levels at night. PMID: 15194882
    11. Results show that the synthesis of 5-hydroxytryptamine and the expression of tryptophan hydroxylase in the dorsal raphe of rat offspring were suppressed by maternal ethanol intake. PMID: 16198203
    12. TPH1 mRNA is 2.5-fold upregulated by the stress in dorsal raphe nucleus but not in pineal gland. PMID: 18197473
    13. Data showed that calcium influx blockaded by nifedipine caused a decrease in tryptophan hydroxylase activity. PMID: 18221757
    14. mRNA for TPH-1 was present in peripheral arteries, with low levels of TPH protein and TPH activity PMID: 18414394
    15. data support the model that increased nocturnal 5-HT synthesis in the pineal gland is mediated by the phosphorylation of TPH1 at the serine 58, which elevates the TPH1 protein content and activity at night PMID: 18705647
