Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

... which appears in the February 24 issue of Nature, presents the first genome-wide study of an amoeba. It is also the first genome sequence to be published from this class of amitochondrial human pathogens. The analysis reveals the degradation of the E. histolytica genome in its transition from a free-living ...

Found: Missing sequence of the human Y chromosome

...ry print issue of GenomeResearch (www.genome.org), presents the sequencing and analysis of 554kilobases of previously uncharacterized sequence from thepericentromeric region of the Y chromosome. This sequence contains a450-kilobase "euchromatic island" with eight presumably active genesflanked by repetitive s...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice

...le online). "Gene therapy in muscular dystrophies presents a unique challenge, because replacement of deficient, therapeutic proteins invokes an immune response that limits the efficacy of the treatment," said Duke medical geneticist Dwight Koeberl, M.D., senior author of the study. "By restricting the expre...

Gene Therapy For Parkinson's Disease Moves Forward In Animals

...erapy, which is very applicable to humans. It even presents theoretical reasons that might solve some of the safety issues that have been raised about GDNF. But many things remain that we still don't understand.?/p> The recent findings in laboratory animals were a joint effort of Lund University in Lund, ...

An entropy-based gene selection method for cancer classification using microarray data

...ne by others using the same data sets. This study presents an entropy-based iterative algorithm for selecting genes from microarray data that are able to classify various cancer sub-types with high accuracy. In addition, the feature set obtained is very compact, that is, the redundancy between genes is reduc...

"In light of findings by insect biologists that certain proteins function as important Bt toxin receptors in some cases, how might glycolipid and protein receptors cooperate to engage this intoxication program...

Scientists solve structure of key protein in innate immune response

...eria. Once CD14 binds to LPS or another ligand, it presents the molecule to other proteins which initiate a strong pro-inflammatory response that stimulates host defenses. "Macrophages and monocytes can recognize distinct structural patterns in various molecules from pathogenic microorganisms," explains Dr. ...

Oceans more vulnerable to agricultural runoff than previously thought, study finds

... Now a new study by Stanford University scientists presents the first direct evidence linking large-scale coastal farming to massive algal blooms in the sea. Writing in the March 10 issue of the journal Nature, the authors conclude that some highly productive regions of the ocean are much more vulnerable to ...

Measuring Enzymes At End Of Cancer Pathway Predicts Outcome Of Tarceva, Taxol

...us that CDK2 is the real target of Tarceva. "This presents a concept that describes how Tarceva works, and it also shows that we have a technology that can rapidly measure the true activity of CDK2 in a tumor sample," Ueno says. First author Fumiyuki Yamasaki, M.D., Ph.D., a post-doctoral fellow, is presenti...

Oldest fossil human protein ever sequenced

...fossils which no longer contain DNA. The research presents the sequence for the bone protein osteocalcin from a Neanderthal from Shandivar Cave as well as osteocalcin sequences from living primates (humans, chimpanzees, gorillas and orangutans). The team found that the Neanderthal sequence was the same as mo...

Report that delayed motherhood decreases life expectancy of mouse offspring
