How genetic and genomic analysis are leading to new therapies in Kawasaki disease Jane Burns UCSD School of Medicine, Department of Pediatrics Abstract: Our first genetic studies of Kawasaki disease (KD) began in 1998 when we found a skewed distribution of two single nucleotide polymorphisms (SNPs) in the promoter region of TNF? that were potentially implicated in increased gene expression. These early observations inspired a small clinical trial of pentoxifylline, a modulator of TNF?...

biosights: February 17, 2014 - Shroom takes embryos to new dimensions

submitted by: JCB
During development, the planar polarized distribution of Rho kinase and Myosin II helps Drosophila germ-band cells intercalate so that the embryo extends along its anterior-posterior axis. Simoes et al. reveal how Rho GTPase and the actin-binding protein Shroom combine to regulate the localization of Rho kinase and actomyosin contractility during axis elongation. This biosights episode presents the paper by Simoes et al. from the February 17, 2014, issue of The Journal of Cell Biology and...

Walt Wilczynski discusses research on the responses by non-mammals to signals during mating competitions

submitted by: nsf

Walter Wilczynski of Georgia State University is researching how non-mammals signal one another in mating competitions, and how these signals influence the behavior of individual males and females. According to Wilczynski's research, an individual's behavioral responses to such signals and whether it loses or wins a mating competition may modify its brain in ways that may influence its future behavior.

Hans Hofmann explains how environment and genetics influence the brains and behavior of cichlid fish

submitted by: nsf
Hans Hofmann of the University of Texas, Austin, is researching the influences of environment and genetics on the brains and behavior of cichlid fish. Cichlids provide excellent model organisms for such studies because thousands of species of cichlids have evolved; many of these species are genetically similar but behaviorally and socially different from one another. Hofmann is using the diversity of cichlid species to help identify which genes regulate various behaviors and evaluate how...

Melina Hale explains how her research of zebrafish is helping to advance brain research

submitted by: nsf

Melina Hale of the University of Chicago is studying neuronal circuits in zebrafish that generate startle responses. Because little is known about how circuits operate in any organism and because startle responses are controlled by relatively simple circuits, an improved understanding of the circuitry of the zebrafish's startle responses is expected to help lay the groundwork for research on more complicated circuits.
