OpGen, Inc. (510 Charmany Drive, Suite 151, Madison, WI 53719, Tel: 608/44'-8100, Fax: 608/441-8101) has completed a whole genome map of the fungal pathogen, Aspergillus fumigatus (strain Af293), for an […]

The article reports that scientists at the institute directed by geneticist J. Craig Venter announced they have successfully implanted the genome of one species of bacteria into another, which they view as a major step towards the synthetic creation of life. Venter's goal is to create cells which might take carbon dioxide out of the atmosphere to make methane for use in other fuels. Outside scientists differed on the scope of the institute's accomplishment.

Focuses on genomic imprinting, which is recognized as a breakthrough in understanding of genetics. Example of how imprinting might influence offspring growth and development; Reasons that genomic imprinting is a wild and amazing discovery; Implication of genomic imprinting and the complexity that lies behind the waddling goslings.

Focuses on the unusual inheritance pattern called imprinting. Biology professor Shirley M. Tilghman's study on the function of the H19 gene; Certain genes as active only if they come from the mother's or father's side; Conflict theory's predicted growth pattern; Experiments conducted on mice; Implications of gene imprinting on improving the efficiency of cloning.

For some genes, either the father's version or the mother's version is active, but not both. Which version of the gene works is determined before conception, as the sperm and egg are developing, in a process called imprinting. By mimicking that process in the lab, and turning off a gene in mice, scientists have produced a change in social dominance behavior. In laboratory tests, mice with the paternal version of the gene known as Grb10 inactivated were more aggressive in their behavior, according to new research in the journal Nature. The researchers had two methods of measuring social dominance. They found that mice with the inactive gene engaged in more social grooming, and nibbled off more fur and whiskers of other mice. Also, when two mice were placed in a tube and approached each other, mice with the inactive gene were less likely to back down and turn away. [ABSTRACT FROM PUBLISHER]

Reports that researchers at Massachusetts General Hospital in Boston (Mass.) suggest a new test appears to predict the outcome of a common breast-cancer treatment, making it one of several predictive "genomic" tests that are moving toward potential use in cancer treatment. Details of the new diagnostic test, which is designed to foretell whether breast-cancer patients are likely to respond to the drug tamoxifen; Companies that have begun marketing genomic tests for breast cancer; Comments from Larry Norton, a cancer specialist at Memorial Sloan-Kettering Cancer Center in New York (N.Y.), suggesting the tests are still too new to offer reliable predictions; Speculation about the future of diagnostics.
