Disease relevance of TGFBI

  • betaig-h3 (TGFBI, keratoepithelin) was first identified as a transforming growth factor-beta1 (TGF-beta1)-inducible gene in a human lung adenocarcinoma cell line [1].
  • CONCLUSIONS: Two mutations in the TGFBI gene (A546D and P551Q) cosegregated with LCD in an extensively studied family that lacked the R124C mutation that frequently accompanies this form of corneal amyloidosis [2].
  • CONCLUSIONS: We concluded that the TGFBI gene is not responsible for causing keratoconus in these patients [3].
  • TGFBI gene mutation analysis in families with hereditary corneal dystrophies from Ukraine [4].
  • These results document the expression of beta ig-h3 in diseased human arterial tissue and support the hypothesis that active TGF-beta plays a role in atherogenesis and restenosis [5].
 

Psychiatry related information on TGFBI

  • CSD/BEM localization of P300 sources in adolescents "at-risk": evidence of frontal cortex dysfunction in conduct disorder [6].
  • These results indicate that CSD has aversive as well as amnesic properties, there exists a gradient of amnesia, dependent on concentration, and that the cortex is not necessary for learning a taste aversion [7].
 

High impact information on TGFBI

  • This suggests, as the last two diseases are characterized by amyloid deposits, that R124 mutated kerato-epithelin (the product of beta ig-h3) forms amyloidogenic intermediates that precipitate in the cornea [8].
  • Granular dystrophy Groenouw type I (CDGG1), Reis-Bücklers (CDRB), lattice type I (CDL1) and Avellino (ACD) are four 5q31-linked human autosomal dominant corneal dystrophies [8].
  • In this issue of Neuron, van den Maagdenberg et al. characterize a mouse with a knockin mutation known to cause familial hemiplegic migraine and provide evidence that a lowered threshold to the triggering of CSD may account for the devastating phenotype of familial hemiplegic migraine [9].
  • Our data show that the increased susceptibility for CSD and aura in migraine may be due to cortical hyperexcitability [10].
  • A kerato-epithelin (betaig-h3) mutation in lattice corneal dystrophy type IIIA [11].
 

Chemical compound and disease context of TGFBI

 

Biological context of TGFBI

  • In reciprocal blocking experiments both proteoglycans inhibited the others binding to beta ig-h3 indicating that they may share the same binding site or that the two binding sites are in close proximity on the beta ig-h3 molecule [14].
  • Lastly, it was observed that beta ig-h3-mediated keratinocyte differentiation was caused by promotion of cell adhesion and not by calcium regulation [15].
  • Subsequent analysis revealed not only induction of Akt phosphorylation by recombinant beta ig-h3 but also blockage of Akt phosphorylation by LY294002, an inhibitor of phosphatidylinositol 3-kinase [15].
  • Six autosomal dominant corneal dystrophies are caused by mutations in the TGFBI (BIGH3) gene on chromosome 5q31: three types of lattice corneal dystrophy (LCD), including type I and type IIIA, granular, Avellino (ACD), and Reis-Bucklers [16].
  • We analysed the TGFBI gene by SSCP analysis and direct sequencing in order to further assess the genotype-phenotype correlation [16].
 

Anatomical context of TGFBI

 

Associations of TGFBI with chemical compounds

 

Physical interactions of TGFBI

  • Biglycan core protein was shown to inhibit the extent of complexing of beta ig-h3 with native and pepsin-collagen VI suggesting that the glycosaminoglycan side chains of the proteoglycan were important for the formation of the large ternary complexes [14].
