View SamplesRationale: Pulmonary arterial hypertension is a common and potentially fatal complication of scleroderma that may involve inflammatory and autoimmune mechanisms. Alterations in the gene expression of peripheral blood mononuclear cells have been previously described in patients with pulmonary arterial hypertension. The ability to identify patients at risk for developing pulmonary hypertension would be clinically beneficial.

View SamplesThe homeobox containing gene Arx is expressed during ventral telencephalon development and it is required for correct GABAergic interneuron tangential migration from the ganglionic eminences to the olfactory bulbs, cerebral cortex and striatum. Its human ortholog is associated with a variety of neurological clinical manifestations whose syntoms are compatible with a loss of cortical interneurons and altered basal ganglia related-activities in humans. Herein, we reported the identification by global expression profiling of a group of genes whose expression is consistently altered in Arx mutant ganglionic eminences. Following analysis revealed the striking ectopic expression in the ganglionic eminences of a number of genes normally not, or only marginally, expressed in the ventral telencephalon. Among them, we functionally analyzed Ebf3, whose ectopic expression in ventral telencephalon is preventingneuronal tangential migration. Further, we showed that Arx is sufficient to repress Ebf3 endogenous expression and that its silencing in Arx mutant tissue might marginally rescue tangential cell movements. Together, these data provide an initial analysis of the molecular pathways regulated by Arx and how their networking might regulate those specific cellular processes during telencephalon development strongly altered by loss of Arx.
Arx acts as a regional key selector gene in the ventral telencephalon mainly through its transcriptional repression activity.

View SamplesHuman herpesvirus-8 (HHV-8) is the causative agent of Kaposis sarcoma and is associated with the angioproliferative disorders primary effusion lymphoma (PEL) and multicentric Castlemans disease (MCD). We have previously described evidence of HHV-8 infection within the pulmonary vasculature of patients with idiopathic pulmonary arterial hypertension (IPAH). We speculated that viral infection of the pulmonary microvascular endothelial cells could cause the angioproliferative phenotype characteristic of severe pulmonary arterial hypertension (PAH). We now demonstrate the ability of HHV-8 to infect human pulmonary microvascular endothelial cells (HPMVECs) in vitro, confirming both latent and lytic infection. HHV-8 infection of HPMVECs resulted in significant changes of gene expression including alterations of pathways integral to both cellular apoptosis and angiogenesis. This infection also results in alterations of genes integral to the bone morphogenic protein (BMP) pathway, including down regulation of bone morphogenic protein receptor 1a (BMPR1a) and bone morphogenic protein 4 (BMP4). Other genes previously implicated in the development of PAH are also altered in expression by HHV-8 infection. These include increased expression of Interleukin-6 (IL-6) and the matrix metalloproteinases (MMP)-1, MMP-2 and MMP-10. Lastly, cells infected with HHV-8 apoptosis resistant. Infection of pulmonary microvascular endothelial cells with human herepesvirus-8 results in alteration of the BMP pathway as well as an anti-apoptotic phenotype, consistent with the development of plexiform lesions characteristic of pulmonary arterial hypertension.
