  • 产品描述：

    NKX2-1 is a homeodomain transcription factor that is required for thyroid genesis and thyroid-specific gene transcription. NKX2-1 is selectively expressed from prenatal development to adulthood in the brain, thyroid gland, parathyroid gland, lungs, skin, and enteric ganglia, and plays a vital role at the interface of the brain, endocrine, and immune systems. NKX2-1 is involved in a number of physiologic processes that are linked to the somatic symptoms that are typical in schizophrenia. NKX2-1 is also important for neurodevelopment and is required for the formation and function of subgroups of neurons, glia, and functional brain networks in schizophrenia.

    The production of the recombinant NKX2-1 antibody includes extracting RNA from spleen cells that are derived from immunized animals, reversely transcribing the RNA into DNA, sequencing and screening antibody genes, amplifying the heavy chain and light chain genes of the antibody using PCR technology, linking and cloning the genes into a plasma vector, and introducing the vector clone into a mammalian cell for functional antibody expression. The recombinant NKX2-1 antibody was purified using Affinity-chromatography. It can be used to detect the NKX2-1 antibody from Human in the ELISA, WB, IHC, FC.

  • 功能：
    Transcription factor that binds and activates the promoter of thyroid specific genes such as thyroglobulin, thyroperoxidase, and thyrotropin receptor. Crucial in the maintenance of the thyroid differentiation phenotype. May play a role in lung development and surfactant homeostasis. Forms a regulatory loop with GRHL2 that coordinates lung epithelial cell morphogenesis and differentiation. Activates the transcription of GNRHR and plays a role in enhancing the circadian oscillation of its gene expression. Represses the transcription of the circadian transcriptional repressor NR1D1.

    1. We observed that hyaline membrane disease is the most common cause of perinatal death among respiratory disorders, and in this disease, the expression of TTF-1 is significantly reduced in terminal bronchioles, distal airways, and alveoli compared to the control group. PMID: 30004050
    2. NKX2-1 expression was upregulated in never-smokers , lung adenocarcinoma and patients with wild-type TP53. A negative correlation between NKX2-1 and miR-365 expression was found but there was no correlation between NKX2-1 and miR-33a expression. NKX2-1 expression impacts prognosis in early-stage non-small cell lung cancer patients, particularly in those with neither TP53 nor KRAS mutations. PMID: 29237428
    3. Study shows that that NKX2-1 directly and positively regulates transcription of cyclin D1 in lung adenocarcinoma. Also, the expression of NKX2-1, but not cyclin D1, is significantly associated with metastatic incidence as an independent good prognostic factor of adenocarcinoma. PMID: 28634225

    11. Because TTF-1 is not detected in the vast majority of cases using a separate antibody clone, 8G7G3/1, we conclude that aberrant staining is due to cross-reactivity to unknown antigen(s). TTF-1 positivity and even Napsin A positivity, therefore, cannot be used as conclusive evidence of pulmonary origin and gastrointestinal origin must be considered in the differential diagnosis PMID: 26469324

Moreover, upregulation of TTF1 was shown to promote the proliferation of HCC cells in vitro. PMID: 26821084
    14. P-AKT and TTF-1 using IHC had statistically significant correlation with EGFR mutation with high negative predictive value PMID: 26905105

    16. TTF-1 immunoreactivity was seen in 19 pulmonary neuroendocrine carcinoma (PNEC) cases (95%) and 13 thymic (TNEC) cases (59.1%). TTF-1 positivity was associated with high sensitivity but low specificity for PNEC, and adding PAX8 negativity significantly increased the specificity. PAX8 positivity alone showed essentially 100% specificity and 86.4% sensitivity for TNEC. PMID: 27761900
    17. Studied the prognostic relevance of thyroid transcription factor 1 (TTF1) copy number alterations (CNAs) and expression levels in non-small cell lung cancer; found TTF1 CNAs and expression high within tumors and between primary and metastatic tumors. PMID: 28378892
    18. it may be useful to combine NAPA and TTF-1 for increased sensitivity in lung cancer diagnostics.

    26. In conclusion, TTF-1 is a useful marker in distinguishing subependymal giant cell astrocytoma from its mimics. Expression of TTF-1 in the fetal medial ganglionic eminence indicates that subependymal giant cell astrocytoma may originate from the progenitor cells in this region. PMID: 27910945

    31. We demonstrated that the 14q13.2q21.1 deletion, which encompasses NKX2-1, but not FOXG1 gene and HPE8 region, identifies a well defined, more benign, microdeletion syndrome PMID: 27148860
    32. Findings suggest that the novel non-transcriptional function of TTF-1 identified in this study may contribute to lung adenocarcinoma development by conferring tolerance to DNA RS, which is known to be inherently elicited by activation of various oncogenes. PMID: 28192407
    33. Immunohistochemical detection of thyroid transcription factor 1, Napsin A, and P40 fragment of TP63 can be used in the subclassification of non-small cell lung carcinomas. PMID: 27045515

    43. EGFR knockdown led to upregulation of NKX2-1, suggesting a negative feedback loop. combined knockdown of NKX2-1 and EGFR in NCI-H1819 lung cancer cells reduced cell proliferation more than knockdown of either alone. PMID: 26556242
    44. TTF-1 had no prognostic value concerning OS, but may serve as a predictor for response to first line chemotherapy in small cell lung cancer. PMID: 25889870
    45. s suggest that NKX2-1 as a tumour suppressor or a tumour promoter in lung adenocarcinoma progression is dependent on p53 status. PMID: 25881545

    49. No TTF1 or EAP1 germline mutations were associated with central pubertal disorders. TTF1 and EAP1 may affect puberty by changing expression in response to other members of puberty-associated gene networks PMID: 24051510
    50. Loss of TTF-1 is associated with low response to chemotherapy in non-small-cell lung cancer. PMID: 24457236
