Man and mouse share genome structures

...rtions of the mouse genome. Until now, they'd been missed by more standard genome analysis tools. Most exciting to Bernstein is the unusual density of histone tags spread over the regions of genome containing the HOX genes, which are key regulators of development. "In most of the genome, we see short stre...

W.M. Keck Foundation funds study of friendly microbes

You could say that the Human Genome Project missed 99 percent of the genes in the adult body. That's because it didn't sequence genes belonging to the vast communities of bacteria that normally live on and in us. Now a $1.45 million grant from the W.M. Keck Foundation to researchers at the School of...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

..., the protocol indicates that the researchers have missed a gene's activation somewhere in their time series. Just as important, according to Bar-Joseph, is whether a DNA microarray summary value exceeds its time sequence value. If that's the case, then researchers have likely identified gene activity that...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

...fference in QT interval, meaning that other genes, missed in this study, certainly contribute to QT length. Now that researchers know that variants of the NOS1AP gene correlate with QT interval length, they hope to figure out exactly how the DNA sequence variations alter the function of the gene, and how c...
