Previously we have reported that missense mutations in the Very Low Density Lipoprotein Receptor gene (VLDLR), causing Dysequilibrium syndrome (DES), disrupt ligand-binding, due to endoplasmic reticulum (ER) retention of the mutants.
We have delineated the phenotype associated with dysequilibrium syndrome in two Omani families and identified the first homozygous missense pathogenic mutation in VLDLR gene with likely founder effect in the southeastern part of the Arabian Peninsula.
Homozygous deletion of the very low density lipoprotein receptor gene causes autosomal recessive cerebellar hypoplasia with cerebral gyral simplification.
We define the neurological characteristics of familial cases from multiple branches of a large consanguineous family with cerebellar ataxia, mental retardation (MR), and dysequilibrium syndrome type 3 caused by a mutation in the recently cloned CA8 gene.
Neonatal diethylstilbestrol (DES) treatment induces polyovular follicles (PFs), which contain more than two oocytes in a follicle, through estrogen receptor (ER) β, not ERα.
Perinatal diethylstilbestrol (DES) treatment induces the polyovular follicle containing two or more oocytes in a follicle of mouse ovary through estrogen receptor (ER) β.
Both treatments increased the levels of all three splice variants of VEGF mRNA and a maximum increase was detected with 10 microM concentrations of PDB or DES treatments after 2 h. Interestingly, both PDB and DES mediated stimulation of VEGF mRNA expression was completely blocked by the PKC inhibitor chelerythrine.
While none of the SNPs' variants were significantly associated with SS or DES in a recessive model, in an additive model the TNFα G risk allele was found higher among SS patients compared to DES (Homozygote-G: 84.2% vs. 70.8%; Heterozygote: 26.9% vs. 11.2%, respectively, <i>p</i> = 0.02).
To report the neuro-ophthalmologic findings in four patients from the same family with cerebellar ataxia, mental retardation, and dysequilibrium syndrome (CAMRQ)2 associated with quadrupedal locomotion.
Primary human corneal epithelial cells (HCEC), an SV40 HCEC cell line or a normal human conjunctival epithelial cell line (IOBA-NHC) were cultured under hyperosmolar stress (HOS) (400-500 mOsm/kg) or with DES associated cytokines (IL-1α/β, TNFα or TGFβ) at concentrations ranging from 1 to 1000 ng/ml for up to 24 h. Epithelial cells were harvested from a human cornea organ culture model following 24 h of desiccation.
