Arx is a homeobox-containing gene with a high degree of sequence similarity between mouse and zebrafish. Arx is expressed in the forebrain and floor plate of the developing central nervous systems of these vertebrates and in the presumptive cortex of fetal mice. Our goal was to identify genes in Xp22.1-p21.3 involved in human neuronal development. Our in(More)
Understanding the factors that govern human forebrain regionalization along the dorsal-ventral and left-right (L-R) axes is likely to be relevant to a wide variety of neurodevelopmental and neuropsychiatric conditions. Recent work in lower vertebrates has identified several critical signaling molecules involved in embryonic patterning along these axes.(More)
Oxidation of 5-methylcytosine in DNA by ten-eleven translocation (Tet) family of enzymes has been demonstrated to play a significant role in epigenetic regulation in mammals. We found that Tet enzymes also possess the activity of catalyzing the formation of 5-hydroxymethylcytidine (5-hmrC) in RNA in vitro. In addition, the catalytic domains of all three Tet(More)
Cytosine DNA methylation is an epigenetic mark in most eukaryotic cells that regulates numerous processes, including gene expression and stress responses. We performed a genome-wide analysis of DNA methylation in the human malaria parasite Plasmodium falciparum. We mapped the positions of methylated cytosines and identified a single functional DNA(More)
Factors that interact with the epidermal growth factor and fibroblast growth factor receptors have numerous effects in the central nervous system (CNS), inducing the proliferation of CNS stem cells and astrocytes and the survival and differentiation of neurons. Both receptors are expressed in the embryonic rodent brain in proliferative and nonproliferative(More)
Cadmium (Cd(2+)) is a toxic heavy metal and a well-known human carcinogen. The toxic effects of Cd(2+) on biological systems are diverse and thought to be exerted through a complex array of mechanisms. Despite the large number of studies aimed to elucidate the toxic mechanisms of action of Cd(2+), few have been targeted toward investigating the ability of(More)
