Disease relevance of Notch4

  • Endothelial expression of constitutively active Notch4 elicits reversible arteriovenous malformations in adult mice [1].
  • Expression of Notch4(int-3), a truncated form of Notch4 having most of its extracellular domain deleted, as a transgene in mice induces the formation of poorly differentiated mammary carcinomas [2].
  • Here we show that blood flow recovery and postnatal neovascularization in response to hindlimb ischemia in haploinsufficient global or endothelial-specific Notch1(+/-) mice, but not Notch4(-/-) mice, were impaired compared with wild-type mice [3].
  • Insertional mutation of the Int3 gene, a member of the Notch gene family, is frequently associated with primary mouse mammary tumors induced by the mouse mammary tumor virus (MMTV) [4].
  • A novel non-mouse mammary tumor virus activation of the Int-3 gene in a spontaneous mouse mammary tumor [5].
 

High impact information on Notch4

  • However, the Notch4 mutation displayed genetic interactions with a targeted mutation of the related Notch1 gene [6].
  • We expressed a constitutively active Notch4, int3, in the adult mouse endothelium by using the tetracycline-repressible system to suppress int3 during embryogenesis. int3 caused profound blood vessel enlargement and AV shunting, which are hallmarks of AVM, and led to lethality within weeks of its expression [1].
  • Vascular patterning defects associated with expression of activated Notch4 in embryonic endothelium [7].
  • In transgenic livers, we showed that DLL4, active Notch4, and ephrin B2 were gradually up-regulated within the hepatocarcinoma progression and expressed on tumor sinusoidal endothelial cells [8].
  • Expression of a truncated Int3 gene in developing secretory mammary epithelium specifically retards lobular differentiation resulting in tumorigenesis [4].
 

Biological context of Notch4

  • Embryos homozygous for mutations of both the Notch4 and Notch1 genes often displayed a more severe phenotype than Notch1 homozygous mutant embryos [6].
  • We also showed that the activation of Notch4 is required for VEGF-induced up-regulation of ephrin B2 and the differentiation of human venous endothelial cells in vitro [8].
  • 9, that developed in a BALB/c mouse, we have found an insertion of a 1.2-kb sequence, consisting of a 5' long terminal repeat and gag sequences of an intracisternal type A particle (IAP) as well as an extra copy of the Notch4/int3 genomic sequences containing exons 23 and 24, into the intron between exons 24 and 25 of the Notch4/int3 gene [9].
  • The int3 oncogene was discovered as a frequent target in mouse mammary tumor virus-induced mammary tumors and encodes the intracellular domain of a Notch4/int3 protein [9].
  • The protein encoded by the Notch4 gene is a member of the Notch/lin-12 family of transmembrane receptor proteins, which have been shown to control cell fate determination and cell differentiation in a wide variety of organisms [2].
 

Anatomical context of Notch4

  • Surprisingly, directed expression of a constitutively active form of Notch4 within mouse endothelial cells produces a similar vascular embryonic lethality [10].
  • RESULTS: Macrophage precursors expressed high levels of Notch1 transcript, while maturing macrophages expressed high levels of both Notch1 and Notch4 [11].
  • Notch4 and Dll-4 mRNAs are synthesized from the 2-cell through to the hatched blastocyst stage [12].
  • These results were attributed to a gain of function modification of the Int3 gene, which led to a restriction of cell fate selection in the affected mammary epithelial cells [4].
  • Previous studies have demonstrated that mammary gland development and function was severely impaired in transgenic mice expressing the truncated Int3 gene product from the MMTV viral promoter [4].
 

Associations of Notch4 with chemical compounds

  • Here, we characterize the expression patterns of Notch1, Notch4, and Jagged1 proteins during the process of folliculogenesis and corpus luteum formation in the mouse ovary, an organ with dynamic physiological angiogenic growth [13].
