Nanoparticle drug stops cancer's spread in mice | Science/AAAS | News - 0 views

  •  
    When a person dies from cancer, the culprit is usually not the original tumor but rather the cancerous cells that spread throughout the body and replicate in distant organs, a process called metastasis. Researchers have long known that metastasizing cancer cells slip their bonds and avoid immune detection by altering the sugars on their surfaces. They've even come up with a would-be drug to prevent such sugar alterations. But that compound interferes with needed sugars on normal cells, too, with lethal results in animals. Now, Dutch researchers report that they've packaged the drug in nanoparticles targeted exclusively to cancer cells, and they've shown that this combination prevents cancer cells from metastasizing in mice.

Deene Veu Latest Research About Genetic Signature Of Cancer | Deene Veu - 0 views

  •  
    A stride to understand the cancer and move towards its prevention, this time experts from around the world involved in searching the genome of cancer have analyzed the mutational signatures, the processes of mutation in the DNA of cells (which are always in the origin of cancer) and they follow a fixed pattern.

A Complex Disorder | The Scientist Magazine® - 0 views

  •  
    Some 20 percent of cancer-related deaths in the U.S. can be attributed to obesity, making it the number-one preventable cause of cancer death in the country. But with myriad metabolic and inflammatory changes associated with obesity, determining the mechanisms that underlie the obesity-cancer link has proven challenging.

How elephants crush cancer | Science/AAAS | News - 0 views

  •  
    Why elephants aren't riddled with tumors poses a weighty problem for researchers. A new study shows that the animals harbor dozens of extra copies of one of the most powerful cancer-preventing genes. These bonus genes might enable elephants to weed out potentially cancerous cells before they can grow into tumors.

Should We Screen for Cancer Genes? | Science | Classroom Resources | PBS Learning Media - 0 views

  •  
    This video excerpt from NOVA examines the dilemma some people face when they are deciding whether to undergo genetic testing. Journalist Catherine Elton describes her decision to refuse a test for BRCA1, a mutation that signals an increased risk of breast and ovarian cancers, despite the history of disease in her family. The video also explains that genetic testing results can help some individuals improve their wellness, prevent the onset of diseases they are at risk for, or lessen the harmfulness of diseases they do contract.

"Encouraging parents to have their sons get the human papillomavirus (HPV) vaccine-rather than just trying to get more girls vaccinated-could ultimately protect more people for the same price, according to a study by a mathematician."

Inoculating against science denial - 0 views

  •  
    Science denial has real, societal consequences. Denial of the link between HIV and AIDS led to more than 330,000 premature deaths in South Africa. Denial of the link between smoking and cancer has caused millions of premature deaths. Thanks to vaccination denial, preventable diseases are making a comeback.

Scientists Discover Children's Cells Living in Mothers' Brains - Scientific American - 0 views

  •  
    The physical connection between mother and fetus is provided by the placenta, an organ, built of cells from both the mother and fetus, which serves as a conduit for the exchange of nutrients, gasses, and wastes. Cells may migrate through the placenta between the mother and the fetus, taking up residence in many organs of the body including the lung, thyroid, muscle, liver, heart, kidney and skin. These may have a broad range of impacts, from tissue repair and cancer prevention to sparking immune disorders.

This protein is mutated in half of all cancers. New drugs aim to fix it before it's too... - 0 views

  •  
    She wanted to understand the effects of mutations that the gene for p53 is prone to. In dozens of simulations, she and her colleagues tracked how common p53 mutations further destabilize the already floppy protein, distorting it and preventing it from binding to DNA. Some simulations also revealed something else: a fingerhold for a potential drug. Once in a while, a small cleft forms in the mutated protein's core. When Amaro added virtual drug molecules into her models, the compounds lodged in that cleft, stabilizing p53 just enough to allow it to resume its normal functions.
