靶點詳情

  • 功能：
    Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.
  • 基因功能參考文獻：
    1. Data suggest that the mutated transthyretin (TTR) seems to have potential as biomarker for early detection of hepatocellular carcinoma (HCC). PMID: 28876464
    2. Serum transthyretin level dramatically decreased in animals displaying decompression sickness symptoms. PMID: 27068327
    3. We conclude that stress upregulates TTR expression in choroid plexus. PMID: 22371232
    4. Decreased trophoblast expression of retinol transport proteins suggest that nitrofen may interfere with the fetal retinol transport resulting in reduced pulmonary RBP and TTR levels and causing pulmonary hypoplasia in CDH. PMID: 22015466
    5. Data demonstrate that, in vitro and in vivo, transthyretin is up-regulated by progesterone, and suggest that this response is mediated through a progesterone receptor-mediated mechanism. PMID: 20535645
    6. Structural basis of negative cooperativity in transthyretin PMID: 11995997
    7. Complex of rat transthyretin with tetraiodothyroacetic acid refined at 2.1 and 1.8 A resolution PMID: 11995998
    8. Comparison of binding interactions of dibromoflavonoids with transthyretin PMID: 11995999
    9. Amyloid formation in rat transthyretin: effect of oxidative stress PMID: 12135814
    10. data show the LR1 gene is up-regulated following short interval successive partial hepatectomy; it may play an important role in liver regeneration PMID: 12508371
    11. Data suggest that monomeric transthyretin may represent an ischemia-specific CSF marker to indicate the sequential changes according to ischemic insults of the brain. PMID: 15469881
    12. Our study provides genetic, behavioural and molecular evidence that TTR is involved in the maintenance of normal cognitive processes during aging by acting on the retinoid signalling pathway. PMID: 17512093
    13. Ttr mRNA expression in dorsal root ganglia and cauda equina. PMID: 18406527
    14. Sex hormones may increase TTR synthesis by the liver, and therefore, may contribute to amyloid deposition. PMID: 18568387
    15. Results suggest that transthyretin is up-regulated by estradiol via a pathway involving estrogen receptors alpha and beta. PMID: 19130215
    16. The expression of transthyretin in brain of a transgenic mouse model of Alzheimer's disease is asymmetric and affected by age and sex. PMID: 19167467
    17. rat and murine TTR have a lower intrinsic beta-aggregation propensity and a similar native beta-structure stability compared with human TTR. PMID: 19602727
    18. Transthyretin is expressed in the pineal gland >30-fold higher than the median expression level in other tissues, at levels similar to those in the choroid plexus. PMID: 19103603
