Huntington disease (HD) is a neurodegenerative disease caused by a mutation in the huntingtin (HTT) gene. HTT is a large protein, interacts with many partners and is involved in many cellular pathways, which are perturbed in HD. Therapies targeting HTT directly are likely to provide the most global benefit. Thus there is a need for preclinical models of HD recapitulating human HTT genetics. We previously generated a humanized mouse model of HD, Hu97/18, by intercrossing BACHD and YAC18 mice with knockout of the endogenous mouse HD homolog (Hdh)...

Previous studies have shown that leptin, an adipocyte-secreted hormone, stimulates ovarian cancer invasion. Here, we investigated the contribution of uPA in leptin-induced ovarian cancer cell invasion. The cell invasion and migration experiments were carried out using matrigel invasion and wound healing assays in ovarian cancer cell lines (OVCAR3, SKOV3and CaoV-3). The mechanism underlying the invasive effect of leptin was examined using cell transfection with Ob-Rb siRNA, pre-treatment with a specific inhibitor of RhoA and ROCK, RhoA activation assay, OB-Rb, Rock and upA protein expression...

BACKGROUND: The X-linked condition "Aarskog-Scott syndrome (AAS)" causes a characteristic combination of short stature, facial, genital and skeletal anomalies. Studies elucidated a causative link between AAS and mutations in the FGD1 gene, which encodes a Rho/Rac guanine exchange factor. FGD1 is involved in regulating signaling pathways that control cytoskeleton organization and embryogenesis. CASE PRESENTATION: FGD1 was studied in an Emirati family with two cases of AAS using PCR amplification and direct sequencing of the entire coding region of the gene...

Overexpression of nuclear factor (NF-κB) or activation of Smad3 by transforming growth factor β (TGF-β1) induced by oncogenes results in overexpression of fibrotic processes and hence cell death. The objective of this study is to examine whether Silymarin (Sil) alone or in combination with Vitamin E (Vit E) and/or Curcumin (Cur) plays a modulatory role against the overexpression of NF-κB, and TGF-β that induced in response to carbon tetrachloride (CCl4) administration. The present work revealed that CCl4 induced elevation of in serum alanine aminotransferase (ALT), Apoptosis regulator (Bax), Smad3, TGF-β, and NF-kB hepatic mRNA expression (using Real-time PCR), administration of Sil alone downregulated these expressions...

More than half of deaths in end-stage kidney disease (ESKD) patients are due to cardiovascular disease. Elevated fibroblast growth factor 23 (FGF-23) was found to be associated with mortality in hemodialysis (HD) patients and correlates with peripheral calcification. Aortic calcification is associated with coronary artery calcification. Both aortic and peripheral vascular calcifications were associated with mortality in chronic kidney disease. We aimed to investigate the relation between intact FGF-23 and cardiovascular calcification in patients with ESKD who were maintained on regular HD...
