Disease relevance of NRG1

  • We have now screened for breaks at NRG1 in paraffin sections of breast tumors [1].
  • Breaks in NRG1 were detected in 6% (19 of 323) of breast cancers and in some lung and ovarian cancers [1].
  • Furthermore, the expression of all three components of the proposed autocrine loop (ie., ErbB-2, ErbB-4, and NRG1-beta) was significantly related to the presence of metastases at diagnosis (P < 0.05) [2].
  • We also demonstrate NRG1-beta expression in 87% (n = 46 of 48) of medulloblastoma primary tumors, with the greatest expression levels occurring in tumors with high ErbB-2 and ErbB-4 receptor coexpression [2].
  • This suggests that the NRG1 locus is a recurring target of translocations in carcinomas [3].
 

Psychiatry related information on NRG1

  • Several disposition genes for schizophrenia (DTNBP1, NRG1, G72) were identified, whereas evidence for specific disposition genes in bipolar disorder is more limited [4].
  • Increasing evidence suggests an overlap in genetic susceptibility across the traditional classification systems that dichotomised psychotic disorders into schizophrenia or bipolar disorder, most notably with association findings at DAOA(G72), DISC1, and NRG1 [5].
  • To replicate this finding and assess the association between age at onset of schizophrenia and the NRG1 Arg38Gln polymorphism, we investigated the prevalence of this polymorphism in a Chinese population (228 schizophrenic disorder patients and 269 controls) [6].
  • A significant linkage signal was observed on D8S1769, which is located 352 kb upstream of the 5' end of the first exon of NRG1 for two ("narrow" and "narrow with auditory hallucination (AH)") of the three adopted phenotype classes [7].
  • Neuregulin-1 polymorphism in late onset Alzheimer's disease families with psychoses [8].
 

High impact information on NRG1

 

Chemical compound and disease context of NRG1

 

Biological context of NRG1

  • This direct replication of haplotype association in a second population further implicates NRG1 as a factor that contributes to the etiology of schizophrenia [16].
  • The NRG1/neuregulins are a diverse family of proteins that arise by alternative splicing from a single gene [17].
  • Currently, the weight of evidence supports NRG1 and DTNBP1 as schizophrenia susceptibility loci, though work remains before we understand precisely how genetic variation at each locus confers susceptibility and protection [18].
  • The recently isolated second family of neuregulins, NRG2, shares its primary receptors, ErbB-3 and ErbB-4, and induction of mammary cell differentiation with NRG1 isoforms, suggesting functional redundancy of the two growth factor families [19].
  • A recurrent chromosome breakpoint in breast cancer at the NRG1/neuregulin 1/heregulin gene [1].
 

Anatomical context of NRG1

  • We previously reported that five breast cancer cell lines have chromosome translocations that break in the NRG1 gene and that could cause abnormal NRG1 expression [1].
  • Comparison of NRG1 transcript expression in peripheral leukocytes from schizophrenia patients and unaffected siblings identified 3.8-fold higher levels of the SMDF variant in patients (P=0.039) [20].
  • At the cellular level, NRG1 mRNA was abundant in hippocampal and cortical pyramidal neurons and some interneurons, and in cerebellar Purkinje cells and Golgi cells [21].
  • We report that neoplastic Schwann cells within schwannomas overexpress multiple alpha and beta transmembrane precursors from the class II and class III NRG-1 subfamilies [22].
  • It can cleave epidermal growth factor (EGF)-like growth factors, such as heparin-binding (HB)-EGF and neuregulin (NRG), from the cell membrane [23].
 

Associations of NRG1 with chemical compounds

 

Physical interactions of NRG1

 

Enzymatic interactions of NRG1

  • In promoter-reporter assay, the luciferase activities of the reporter constructs, including the putative NF-kappa B site deleted and mutated form were significantly reduced after HRG-beta 1 treatment as compared with the 1.5-kb VEGF-C promoter [32].
 

Co-localisations of NRG1

 

Regulatory relationships of NRG1

  • RESULTS: Our results demonstrate that NRG activates ErbB-2/ErbB-3 heterodimers and induces cell death of LNCaP cells [25].
  • In this study, we identified that HRG-beta 1 stimulated up-regulation of VEGF-C mRNA and protein of human breast cancer cells in a dosage- and time-dependent manner and that this up-regulation was de novo RNA synthesis-dependent [32].
  • Interestingly, the HRG-beta 1-induced NF-kappa B activation cascade was also effectively blocked by SB203580 treatment or p38AF transfection [32].
  • Neuregulin-1 activates the JAK-STAT pathway and regulates lung epithelial cell proliferation [30].
  • Here we show that NDF inhibits EGF binding in a cell type-specific manner [29].
  • PKA directly phosphorylated ErbB2 on Thr-686, a highly conserved intracellular regulatory site that was required for the PKA-mediated synergistic enhancement of neuregulin-induced ErbB2-ErbB3 activation and proliferation in SCs [33].
 

Other interactions of NRG1

  • This sequence-independent effect of the N-terminal domain correlates with an enhanced ability of full-size neuregulin 1 to disrupt higher order oligomers of the ERBB3 extracellular domains in vitro [34].
  • Furthermore, PG-J(2) can abolish the NRG1 and NRG2-induced increase in anchorage-independent growth of these cells [35].
  • Neuregulins 1, 2 and 3 (NRG1, NRG2 and NRG3) are expressed in the mammalian nervous system [36].
  • The c-erbB-4 receptor and all of the ligands examined, neuregulin alpha, neuregulin beta, and betacellulin, were expressed at significantly higher levels in the secretory as compared with the proliferative phase of the menstrual cycle, suggesting a role for these proteins in endometrial maturation [37].
  • NRG1 encodes the Neuregulins 1 (formerly the Heregulins), ligands for members of the ErbB/epidermal growth factor-receptor family, which includes ErbB2/HER2 [1].
