Nuclei swap to stop disease?

By | April 14, 2010

A technique may one day prevent something that is currently unpreventable -- the transmission of mitochondrial diseases from mother to child, according to a proof-of-concept paper published online today (April 14) in Nature. Blastocyst on day 5 after fertilizationImage: Wikimedia commons, EkemThe authors swapped the nuclei from one fertilized human egg with the nuclei from another, creating an embryo with nuclear DNA from the donor egg, but mitochondrial DNA primarily from the recipient. They s


Top killers share genes

By | April 12, 2010

Cancer, obesity, and even atherosclerosis share a common set of differentially expressed genes, suggesting a diverse number of human diseases share the same disrupted biological pathways, according to new research published this week in Cancer Cell. The genetic link also suggests that drugs currently used for the treatment of metabolic and cardiovascular diseases might also be used against cancer, researchers say.

Gut bacteria are what we eat

By | April 7, 2010

Gut microbes, which help humans degrade otherwise indigestible plant material, acquire some crucial digestive enzyme genes from the bacteria in the food we eat, according to a study published this week in Nature. This new finding provides an example of horizontal gene transfer by which diet can influence the genetic diversity and functionality of the human gut microbiome.

The stem cell banking crisis

By | April 7, 2010

The National Institutes of Health (NIH) has allowed a contract for the dissemination of embryonic stem cell lines approved for US government funding to lapse, shuttering a key stem cell bank, and doubling the price researchers pay for samples of some human embryonic stem cell (hESC) lines. Human embryonic stem cellsImage: Wikimedia commons, Nissim BenvenistyResearchers hoped that stem cell research would be moving forward by leaps and bounds with the number of hESC lines approved for federal fu
