Cloning, mapping, and expression of two novel actin genes, actin-like-7A (ACTL7A) and actin-like-7B (ACTL7B), from the familial dysautonomia candidate region on 9q31.

Apo E is thought to mediate the removal of remnant lipoproteins from the plasma by virtue of its ability to bind to hepatic lipoprotein receptors.In F. Dys. patients, remnant-like lipoproteins accumulate, apparently because of delayed clearance by the liver.
Fullerene derivatives inhibited the phorbol myristic acid/oxidized low-density lipoprotein-induced differentiation of macrophages into foam cells as determined by lipid staining and morphology.Lipoprotein-induced generation of TNF-α, C5a-induced MC activation, ICAM-1 driven adhesion, and CD36 expression were significantly inhibited in FD treated cells compared to non-treated cells.
We sought to inspect the role of AMD3100, which acts as an antagonist of stromal cell-derived factor-1/CXC chemokine receptor 4 on the formation of neointima in rabbit saccular aneurysm after flow diverter (FD) treatment.
Interestingly, dystonin is significantly more abundant in cells of familial dysautonomia patients with IKBKAP (I-κ-B kinase complex-associated protein) mutation compared to fibroblasts of controls, suggesting that upregulation of dystonin is responsible for the milder course in familial dysautonomia.
The ability to modulate the production of the wild-type transcript in cells bearing the splice-altering familial dysautonomia (FD) causing mutation in the IKBKAP gene prompted a study of the impact of a panel of pharmaceuticals on the splicing of this transcript, which revealed the ability of the cardiac glycoside digoxin to increase the production of the wild-type, exon-20-containing, IKBKAP-encoded transcript and the full-length IκB-kinase-complex-associated protein in FD-derived cells.
The common familial dysautonomia (FD) mutation results in tissue specific mis-splicing with reduced amount of wild-type (WT) IkappaB kinase associated protein gene (IKBKAP) mRNA and ELP1.
We recently identified a mutation in the I-kappa B kinase associated protein (IKBKAP) gene as the major cause of familial dysautonomia (FD), a recessive sensory and autonomic neuropathy.

The molecular hallmark of familial dysautonomia (FD) is the splicing mutation of Elp1 [also known as IκB kinase complex-associated protein (IKAP)] in the nervous system that is believed to be the primary cause of the devastating symptoms of this disease.
We show that the mutant IKBKAP transgene is misspliced in this model in a tissue-specific manner that replicates the pattern seen in FD patient tissues.
To better understand the specificity of neuron loss in FD, we modeled the molecular mechanisms of IKBKAP mRNA splicing by studying human olfactory ecto-mesenchymal stem cells (hOE-MSCs) derived from FD patient nasal biopsies.
