(Massachusetts General Hospital) A team of cancer researchers from several Boston academic medical centers has discovered a potential treatment for a group of tumors that have resisted previous targeted therapy approaches. In their Nature Medicine report, receiving early online release, the investigators report that combining two different kinase inhibitors ...

When mice that lack steroid receptor-2, a master regulator gene called a coactivator, fast for a day, their blood sugar levels plummet. If they go another day without food, they will die. The severity of the hypoglycemia was unexpected, according to an article in Science.

Metabolic diseases -- in particular the increasingly prevalent type 2 diabetes -- are caused by a complex interaction between genetic disposition and unfavorable lifestyle, above all unbalanced diet and too little physical exercise. Researchers have now for the first time been able to show a relationship between the genetic make-up ...

(Public Library of Science) Common genetic polymorphisms induce major differentiations in the metabolic make-up of the human population, according to a paper published Nov. 28 in the open-access journal PLoS Genetics. An international team of researchers, led by Karsten Suhre, has conducted a genome-wide association study with metabolomics, identifying ...

Cells can turn on tumor-promoting growth circuits by falsely reporting critical genetic information during the process of transcription: making RNA from DNA. Damage to the DNA making up a gene can lead to a misreading of the gene as it is made into RNA, a process called transcriptional mutagenesis. Transcriptional ...

Researchers have developed an unlimited number of pure insulin-producing cells from mouse embryonic stem cells. The cells, which have the same sub-cellular structures as the insulin-producing cells naturally found in the pancreas, were highly effective in treating diabetes in the mouse model.
