Target Data

Function Neurofilaments usually contain three intermediate filament proteins
Gene References into Functions
  1. In newborns undergoing cardiac surgery, phosphorylated axonal neurofilament heavy chain was decreased at 0 hours in both the cardiopulmonary bypass and deep hypothermic circulatory arrest groups compared to baseline. PMID: 29945509
  2. Phosphoneurofilament heavy chain level was higher in ALS patients than in controls PMID: 27538346
  3. Data suggest that high CSF NfH levels are an early predictor of later brain and spinal cord atrophy in multiple sclerosis patients. PMID: 27207456
  4. Findings in the dorsolateral prefrontal cortex in schizophrenia provide evidence of altered proteins involved in synaptic function (FABP4), cytoarchitecture organization (NEFH), and circadian molecular clock signaling (CSNK1E), which may be contributing to the cognitive and/or negative symptoms in this disorder. FABP4, CSNK1E and NEFH could become potentially useful biomarkers for schizophrenia. PMID: 27236410
  5. Unique deletions of two nucleotides causing frameshifts near the end of the NEFH coding sequence were identified in two Charcot-Marie-Tooth disease families. Using electroporation of chick embryo spinal cord, confirmed that NEFH mutants form aggregates in vivo and trigger apoptosis of spinal cord neurons. PMID: 28709447
  6. This study confirmed the general applicability of the monocentric obtained cut-off values for neurofilamens in ALS, especially for pNfH PMID: 27415180
  7. data support the use of Cebrospinal fluid phosphorylated NFH as a prognostic biomarker for amyotrophic lateral sclerosis. PMID: 28628244
  8. Study found a significant correlation between values of 8-hydroxy-2'-deoxyguanosine and phosphorylated NF-H only in clinically isolated syndrome group. While the plasma values of 8-hydroxy-2'-deoxyguanosine reflect the degree of acute demyelination in clinically isolated syndrome, phosphorylated NF-H values reflect that in relapsing-remitting multiple sclerosis. PMID: 27295058
  9. Results provide evidence that in particular pNfH can be used as a good diagnostic biomarker of ALS at the diagnostic stage. Moreover, results indicate that NfL may be useful in monitoring disease progression in a subset of patients. PMID: 28500227
  10. Level of neurofilament heavy chain and light chains were significantly elevated in the cerebrospinal fluid of Amyotrophic Lateral Sclerosis (ALS) patients compared to healthy controls/controls without parenchymal central nervous system involvement and ALS mimic disease patients. PMID: 27732645
  11. Study found a significant increase of pNF-H levels in both plasma and CSF in amyotrophic lateral sclerosis patients PMID: 27423602

  13. This study demonstrated that Higher NF-L concentrations (beta = -0.26) were associated with functional decline in patients with vascular burden. PMID: 25633679
  14. Phospho-NFH levels were significantly higher in amyotrophic lateral sclerosis patients in comparison with controls, in particular in fast progressors. PMID: 25261856
  15. Data identified NEFH methylation as a candidate epigenetic marker for prognosis of RCC patients as well as prediction of anti-vascular endothelial growth factor-based therapy response. PMID: 24464810

  19. In conclusion, pNfH represents a promising candidate for inclusion in a panel of diagnostic and prognostic biomarkers. PMID: 23134506
  20. CSF and intrathecal levels and CSF/serum ratios of anti-NFH antibodies were increased in the CIS patients early developing multiple sclerosis. PMID: 23632043
  21. These data support further study of pNF-H in CSF, serum and plasma as a potential amyotrophic lateral sclerosis biomarker PMID: 23117489
  22. NF-H levels increase significantly faster in children who have a worse Glasgow Outcome Scale following traumatic brain injury, or died. PMID: 21976236

  24. Serum neurofilament protein H levels were significantly elevated in stroke patients compared to healthy controls. PMID: 21349546
  25. Data suggest that a deficiency of cellular neuroprotective mechanisms (decrease of sAPP) is linked to progressive neuro-axonal damage (increase of NfH(SMI35)) and to progression of disease. PMID: 21858182
  26. Data show that RNA interference-mediated knockdown of NEFH accelerated ESCC cell growth in culture and increased tumorigenicity in vivo. PMID: 20140245
  27. NEFH is phosphorylated at serine 493 by GSK3b PMID: 12130654
  28. NEFH gene is involved in the pathogenesis of sporadic motor neuron disease PMID: 14722583
  29. mutations in neurofilaments are possible risk factors that may contribute to pathogenesis in amyotrophic lateral sclerosis in conjunction with one or more additional genetic or environmental factors, but are not significant primary causes PMID: 16084104
  30. A subgroup of FTD patients had remarkably high CSF levels of NfH. The degree of NfH phosphorylation was increased in FTD compared to both other groups. PMID: 17290105

  35. cerebrospinal fluid phosphorylated forms of neurofilament heavy subunit are not molecular markers of axonal damage for HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) probably due to the slow progression of this disease. PMID: 19678766
