Disease relevance of ZIC3

  • These patients occasionally also show spina bifida, indicating that genetic variation in human ZIC3 may contribute to other congenital malformations, including neural tube defects [1].
  • The frameshift allele is also associated with situs inversus among some heterozygous females, suggesting that ZIC3 functions in the earliest stages of LR-axis formation [2].
  • Mutations in the zinc finger transcription factor ZIC3 cause X-linked heterotaxy and have also been identified in patients with isolated congenital heart disease (CHD) [3].
  • Identification and functional analysis of ZIC3 mutations in heterotaxy and related congenital heart defects [3].
  • METHODS: Neovascularization was investigated in 14 explanted hearts from patients with ischemic cardiomyopathy (ICMP) who had been bridged to HTX with PGE-1 (8+/-1 mg/kg/min, 97+/-75.6 days) and compared with 14 hearts who did not receive PGE-1 prior to HTX [4].
 

High impact information on ZIC3

  • From this chromosomal region we have positionally cloned ZIC3, a gene encoding a putative zinc-finger transcription factor [2].
  • X-linked situs abnormalities result from mutations in ZIC3 [2].
  • Functional analysis of all currently known ZIC3 point mutations indicates that mutations in the putative zinc finger DNA binding domain and in the N-terminal domain result in loss of reporter gene transactivation [3].
  • It is surprising that transfection studies demonstrate aberrant cytoplasmic localization resulting from mutations between amino acids 253-323 of the ZIC3 protein, indicating that the pathogenesis of a subset of ZIC3 mutations results at least in part from failure of appropriate nuclear localization [3].
  • 1. Further analysis of this family has revealed two recombinations that place HTX1 between DXS300 and DXS1062, an interval spanning approximately 1.3 Mb in Xq26 [5].
 

Chemical compound and disease context of ZIC3

 

Biological context of ZIC3

 

Anatomical context of ZIC3

  • Disruption of gradient expression of Zic3 by retroviral overexpression resulted in mis-targeting of retinal axons and some axons misrouted to the sub-retinal space at the photoreceptor side of the retina [10].
  • A complex syndrome of left-right axis, central nervous system and axial skeleton defects in Zic3 mutant mice [11].
  • Zic3 is not expressed in the node during primitive streak stages but is expressed in and around the node beginning from the head fold stages of development [12].
  • The Zic3 expression in the mesoderm is induced by activin (beta) or Vg1, which are also involved in the left-sided signal in L-R specification [13].
  • Direct titration of quinacrine into suspensions of a high concentration of AcChR-associated membranes yielded an upper limit to the binding stoichiometry of 1.4 HTX- or PCP-displaceable quinacrine binding sites/AcChR functional units [14].
 

Associations of ZIC3 with chemical compounds

  • Specific labeling required the presence of high concentration of agonist and was inhibited by reversible noncompetitive antagonists including proadifen, meproadifen, perhydrohistrionicotoxin (HTX), and tetracaine when present at concentrations consistent with the binding affinity of these compounds for the allosteric antagonist site [15].
  • Especially within the 1st year after HTX, luminal loss is influenced not only by an increase in plaque area but by a decrease in total vessel volume as well [16].
  • Acetylcholine induced significant epicardial vasodilation in control subjects and vasoconstriction in HTX, as well as a marked increase in CBF in both groups [17].
  • METHODS: Genotyping and assessment of fasting HCY levels were performed in a cohort of 146 HTX recipients and correlated to the onset and progression of CAVD, assessed by serial angiography [18].
  • In HTX, phenylephrine infusion increased Ees, Ea, EW, PVA, and MVO2 without modifying Ees/Ea, EW/PVA, PVA/MVO2, and EW/MVO2 [19].
 

Other interactions of ZIC3

 

Analytical, diagnostic and therapeutic context of ZIC3

  • Pattern of remodeling was analyzed in patients "early" (n = 15, BL study 1.4+/-0.7 months after heart transplantation [HTX]) compared with "late" after HTX (n = 15, BL 46.1+/-29.1 months) [16].
  • Measurements were made at baseline in 11 control subjects and 9 heart transplant recipients (HTX) without rejection and were repeated after phenylephrine in the latter group [19].
  • BACKGROUND: The aim of the present analysis was to define the role of simultaneous heart and kidney transplantation (HNTX) using organs from the same donor by evaluation of clinical strategy and achieved outcome compared with a reference group of concurrently single heart transplant (HTX) and kidney transplant (NTX) recipients [23].
  • Only 3 patients (4%) in the control group had PRA > 10% at the time of HTX [24].
  • CONCLUSION: Patients with LVAD support before HTX do not appear to be at increased risk for significant allograft rejection in the first year or for death within the first 2 years after transplantation [24].
