Disease relevance of ING4

 

High impact information on ING4

 

Chemical compound and disease context of ING4

  • In addition to its nuclear functions, cytoplasmic ING4 interacts with liprin alpha1 to regulate cell migration and, with its known antiangiogenic function, may prevent invasion and metastasis [5].
 

Biological context of ING4

 

Anatomical context of ING4

 

Associations of ING4 with chemical compounds

 

Physical interactions of ING4

  • However, which region of ING4 could have contributed to the binding to p53 remains largely unclear [8].
 

Regulatory relationships of ING4

 

Other interactions of ING4

  • Furthermore, the interaction of ING4 to p53 was abrogated in vitro and in vivo when certain mutations or the entire deletion of the NLS domain occurred [8].
  • The potential tumor suppressor ING4 was recently shown to be a critical regulator of NF-kappaB-mediated IL-8 transcription and subsequent angiogenesis in gliomas [9].
  • These results indicate that p29ING4 and p28ING5 may be significant modulators of p53 function [10].
  • These data provide evidence for the role of ING4 in mediating the effect of low K intake on ROMK channel activity by stimulation of p38 and ERK MAPK [11].
 

Analytical, diagnostic and therapeutic context of ING4

  • Quantitative real-time RT-PCR analysis demonstrated decreased expression of ING4 mRNA in 76% of primary tumors as compared with that of matched normal samples [3].
  • In mice, xenografts of human glioblastoma U87MG, which has decreased expression of ING4, grow significantly faster and have higher vascular volume fractions than control tumours [4].
  • Using the ING4 wobble isoforms as an example, we demonstrated that capillary electrophoresis can precisely separate DNA fragments with a small difference in size (<3 nt) and can be used to quantify the expression ratio, which thus measures the distribution of each splicing-junction wobble isoform in tissues [12].
