In each type of cell, like a muscle cell or a skin cell, different genes are expressed (turned on) or silenced (turned off). If the cells that are turned on mutate, they could—depending on what role ...

Most pharmaceuticals sold today have their origin in a biochemistry laboratory. Drug discovery has traditionally started with a biochemical pathway implicated in a pathophysiological process. An ...

Phase I and Pharmacologic Study of Oral ZD9331, A Novel Nonpolyglutamated Thymidylate Synthase Inhibitor, in Adult Patients With Solid Tumors ABSTRACT: Aberrant gene expression is critical for tumor ...

A standard Internet protocol that checks errors made during email transmissions has now inspired a revolutionary method to transform DNA microarray analysis, a common technology used to understand ...

Companies in the microarray sector are trying to take the technology out of core facilities and put it into the hands of individual researchers by developing technologies such as smaller, less-costly ...

Microarrays are used to detect the expression of a diverse range of thousands of genes. They include microscopic slides that can be printed with a spot of a known sequence of DNA. This sequence then ...

Microbial comparative genomics provides insights into gene function, bacterial speciation and evolutionary relationships. In the August 14 Proceedings of the National Academy of Sciences, Murray et al ...
