  • 最新研究进展：
    ENO2，又称为神经元特异性烯醇化酶，是一种在神经元中广泛表达的酶，参与多种神经过程的调节，包括神经元的分化、迁移、突触形成和记忆等。最新的研究显示，ENO2的异常表达与神经系统疾病的发生和发展密切相关，例如阿尔茨海默病、帕金森病和多发性硬化症等。
  • 功能：

    1. CgA and NSE are clinically valuable tumor markers in neuroblastoma and they merit prospective clinical evaluations as such. PMID: 29737901
    2. the major result was that elevated serum NSE appears to correlate with prognosis in advanced prostate cancer (PCa), particularly in patients with progressive and metastatic castration-resistant PCa. Based on the existing literature, the role of serum NSE in PCa patients should be further evaluated. PMID: 28885659
    3. Identify a possible cross-reactive conformational B cell epitope, shared by Borrelia enolase and gamma enolase, but not by alpha enolase. We hypothesize that this autoantibody interferes with glycolysis in neuronal cells, as the physiological basis for chronic symptoms in at least some cases of post-treatment Lyme disease syndrome. PMID: 29317049
    4. We investigated the possible correlation between TCD results and S100B, NSE and LDH levels as well as between NSE-LDH and S100B-LDH levels by regression analysis. We found a statistically significant relationship for both NSE, S100B with LDH. PMID: 29244749
    5. ENO2 promoted cell growth, glycolysis, and glucocorticoid resistance, all of which were effectively inhibited when ENO2 was silenced with shRNAs and up-regulated various glycolysis-related genes and enhanced Akt activity with subsequent glycogen synthase kinase3beta (GSK-3beta) phosphorylation, inducing cell proliferation and glycolysis. PMID: 29689546
    6. High Neuron-Specific Enolase expression is associated with poor response to therapy in small cell lung cancer. PMID: 28127669

    17. Suggest that NSE may be a practical parameter that can be used to monitor TB activity and treatment response. Elevated serum NSE level originates, at least in part, from macrophages in granulomatous lesions. PMID: 27271274
    18. HER2 and NSE serum levels were independent prognostic factors in patients with brain metastases in breast cancer. Serum HER2 and MMP-9 appear to be associated with BM in metastatic BC patients. Their predictive value for BM still needs to be evaluated in further prospective studies. PMID: 27464303

    20. The study aimed to identify a small set of genetic signatures that may reliably predict the individuals with a high genetic propensity to heroin addiction. A set of 4 genes (JUN, CEBPB, PRKCB, ENO2, or CEBPG) could predict the diagnosis of heroin addiction with the accuracy rate around 85% in our dataset. PMID: 27495086
