Data from: Orientation of mouse H19 ICR affects imprinted H19 gene expression through promoter methylation–dependent and –independent mechanisms
<p>The mouse <em>Igf2/H19</em> locus is regulated by genomic imprinting, in which the paternally methylated <em>H19</em> imprinting control region (ICR) plays a critical role in mono-allelic expression of the genes in the locus. Although the maternal allele–specific insulator activity of the <em>H19</em> ICR in regulating imprinted <em>Igf2</em> expression has been well established, the detailed mechanism by which the <em>H19</em> ICR controls mono-allelic <em>H19</em> gene expression has not been fully elucidated. In this study, we evaluated the effect of <em>H19</em> ICR orientation on imprinting regulation in mutant mice in which the <em>H19</em> ICR sequence was inverted at the endogenous locus. When the inverted-ICR allele was paternally inherited, the methylation level of the <em>H19</em> promoter was decreased and the <em>H19</em> gene was derepressed, suggesting that methylation of the <em>H19</em> promoter is essential for complete repression of <em>H19</em> gene expression. Unexpectedly, when the inverted allele was maternally inherited, the expression level of the <em>H19</em> gene was lower than that of the WT allele, even though the <em>H19</em> promoter remained fully hypomethylated. These observations suggested that the polarity of the <em>H19</em> ICR is involved in controlling imprinted <em>H19</em> gene expression on each parental allele, dependent or independent on DNA methylation of the <em>H19</em> promoter.</p>

Orientation behavior of riparian Long-Jawed Orb Weavers (Tetragnatha elongata) after displacement over water
<p>Many organisms possess remarkable abilities to orient and navigate within their environment to achieve goals. We examined the orientation behavior of a riparian spider, the Long-Jawed Orb Weaver (<i>Tetragnatha elongata</i>), when displaced onto the surface of the water. When displaced, spiders move with alternating movements of the first three leg-pairs while dragging the most posterior pair of legs behind them. In addition, spiders often perform a series of orientation behaviors consisting of concentric circles before ultimately choosing a path of travel directly towards the nearest point to land. While the number of orientation behaviors increased with increasing distance from shore, distance had no effect on the direction of travel, which was significantly oriented toward the closest shoreline. These results indicate a complex ability to orient toward land when displaced onto water, possibly to decrease the amount of time on the surface of the water and thus decrease predation risk.</p>

Wasp controls oriented migration of endothelial cells to achieve functional vascular patterning
<p>Endothelial cell migration and proliferation are essential for the establishment of a hierarchical organization of blood vessels and optimal distribution of blood. However, how these cellular processes are quantitatively coordinated to drive vascular network morphogenesis remains unknown. Here, using the zebrafish vasculature as a model system, we demonstrate that the balanced distribution of endothelial cells as well as the resulting regularity of vessel caliber, is a result of migration of cells from veins connected to arteries and cell proliferation in veins. We identify the Wiskott-Aldrich Syndrome protein (WASp) as an important molecular regulator of this process and show that loss of coordinated migration from veins to arteries upon <i>wasb </i>depletion results in aberrant vessel morphology and the formation of persistent arteriovenous shunts. We demonstrate that WASp achieves its function through the coordination of junctional actin assembly and PECAM1 recruitment and provide evidence that this is conserved in human. Together, we demonstrate that functional vascular patterning in the zebrafish trunk utilizes differential cell movement regulated by junctional actin, and that interruption of differential migration may represent a pathomechanism in vascular malformations.</p>
