Personal health recommendations and diets tailored to better prevent diseases may be in our future, just by focusing on genetics. Researchers at Kansas State University recently published an academic journal article discussing the potential for nutrigenomics, a field that studies the effects of food on gene expression. The researchers discussed the possibility of using [...]

The molecular machinery that switches on a gene known to cause breast cancer to spread and invade other organs has been identified by an international team led by scientists at The University of Texas M. D. Anderson Cancer Center. The paper was published in Nature Cell Biology’s advanced online publication.

A team of McGill Chemistry Department researchers led by Dr. Hanadi Sleiman has achieved a major breakthrough in the development of nanotubes — tiny “magic bullets” that could one day deliver drugs to specific diseased cells. Sleiman explains that the research involves taking DNA out of its biological context. So rather than being used as [...]

A federal judge struck down patents on two genes linked to breast and ovarian cancer. The decision, if upheld, could throw into doubt the patents covering thousands of human genes and reshape the law of intellectual property. United States District Court Judge Robert W. Sweet issued the 152-page decision, which invalidated seven patents related to [...]

A Columbia scientist has become the first to grow a complex, full-size bone from human adult stem cells. Gordana Vunjak-Novakovic, a professor of biomedical engineering at the Fu Foundation School of Engineering and Applied Science, reports that her team grew a temporomandibular joint (TMJ) from stem cells derived from bone marrow. Her work is reported [...]

The key to human individuality may lie not in our genes, but in the sequences that surround and control them, according to new research by scientists at the Stanford University School of Medicine and Yale University. The interaction of those sequences with a class of key proteins, called transcription factors, can vary significantly between two [...]

Scorpion venom is notoriously poisonous — but it might be used as an alternative to dangerous and addictive painkillers like morphine, a Tel Aviv University researcher claims. Prof. Michael Gurevitz of Tel Aviv University’s Department of Plant Sciences is investigating new ways for developing a novel painkiller based on natural compounds found in the [...]

Regulatory proteins common to all eukaryotic cells can have additional, unique functions in embryonic stem (ES) cells, according to a study in the Journal of Cell Biology. If cancer progenitor cells — which function similarly to stem cells — are shown to rely on these regulatory proteins in the same way, it may be possible [...]

In ongoing work to identify how genes interact with social environments to impact human health, UCLA researchers have discovered what they describe as a biochemical link between misery and death. In addition, they found a specific genetic variation in some individuals that seems to disconnect that link, rendering them more biologically resilient in the face [...]
