Man and mouse share genome structures

...olleagues, for the daunting computational analysis required to interpret the resulting data. In most cases, the mapped tags coincided with the transcription starting points of active genes, as they and others had seen earlier in the yeast. Unexpectedly, they also found tags idling over regions near genes. Th...

Plants, animals share molecular growth mechanisms

... and disease. "These genes and their proteins are required for normal development and for normal cell-to-cell adhesion," Szymanski said. "They affect the growth of the whole plant and also the shape and size of types of cells in the plant." Results of the study are published in the February issue of the jou...

Novel Enzyme Shows Potential As An Anti-HIV Target

...ion controls transcription by recruiting cofactors required for transcription. Acetylation and deacetylation enzymes can also target other proteins. Of the three classes of deacetylases known to modify human histones, the sirtuins (SIRT1?) appear to preferentially target a number of nonhistone proteins. Ott ...

Brown and McDougall collected rocks containing volcanic debris, which McDougall dated to approximately 195,000 years old. Forty years ago, radiometric dating methods were less accurate...

Scientists rid stem cell culture of key animal cells

...portant ingredient in the mix of culture materials required to keep stem cells in their undifferentiated "blank slate" state. Embryonic stem cells are capable of forming any of the 220 tissues and cells in the human body and, in culture, are constantly trying to migrate down different developmental pathways. ...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

... are packaged in yeast. To go from yeast to humans required a technological breakthrough, however. "Most prior studies involved only single genes, but we wanted to investigate entire chromosomes, which contain hundreds of genes," Bernstein notes. He and Schreiber enlisted the help of Affymetrix, which makes...
