Researchers identify gene involved in dog size

... gene family in prostate cancer susceptibility has already been well established. Building upon previous research showing that the IGF-1 gene plays an important role in growth, body size and longevity in mice, the dog researchers used physical observations, X-ray imaging and DNA sequencing and genotyping ...

Penn researchers show how nanocylinders deliver medicine better than nanospheres

...mpoo and some foods. Although synthetic, PEGs have already been approved as biocompatible to humans, making them ideal carriers, note the researchers. While these findings could impact the way lung cancer is treated, this discovery of how to more effectively deliver drugs to the body could also improve th...

Need oxygen? Cells know how to spend and save

...xygen is low. And they learned that because COX4-1 already is in the mitochondria, the swap for COX4-2 occurs when the sensor turns on yet another gene that produces an enzyme to specifically chew up COX4-1. Engineering human cells to lack this enzyme and subjecting them to low oxygen, the scientists found t...

Cambodian vulture nests offer hope for species

...and support—longer-term conservation measures. "We already have a successful WCS model working in the Norther... The Cambodia Vulture Conservation Project has already been successful in helping stem the decline in Asia's vultures in Cambodia through a combination of ...

Eating with our eyes: Why people eat less at unbused tables

... watching the Super Bowl who saw how much they had already eaten -- in this case, leftover chicken-wing bones -- ate 27 percent less than people who had no such environmental cues, finds a new Cornell study. The difference between the two groups -- those eating at a table where leftover bones accumulated co...

New details on how the immune system recognizes influenza

...gy officer at LIAI. "Hundreds of flu epitopes have already been published and are now in the database, but critical gaps become apparent when one looks for human antibody targets." Plans for the future include adding data on epitopes that are involved in autoimmune diseases and epitopes that trigger allerg...

Woven scaffolds could improve cartilage repair

...hers said. "By taking a synthetic material that already has the properties of cartilage and combining it with living cells, we can build a human tissue that can be integrated rapidly into the body, representing a new approach in the field of tissue engineering," Moutos said. "Once implanted, the cartil...

Discovery could lead to better control of hemorrhagic fever viruses

...Serendipitously, several anti-TfR1 antibodies have already been developed as anticancer therapeutics (cancer cells are also high in TfR1), and some have already been through clinical trials. Choe's lab will test these antibodies, hoping to find one that inhibit...

Farmed salmon could become an invasive species in forest streams

...pulations. Escaped salmon could compete with already at-risk species, such as steelhead. "Given the precarious state of many of our native salmon stocks," explains Bisson, "it seems prudent to be safe rather than sorry, and to be diligent in monitoring any reports of Atlantic salmon in Pacific Nor...

Enhancing activity of marijuana-like chemicals in brain helps treat

...er, PhD, the study's lead author, combined a drug already used to treat Parkinson's disease with an experimental compound that can boost the level of endocannabinoids in the brain. When they used the combination in mice with a condition like Parkinson's, the mice went from being frozen in place to movin...

Fighting influenza & co. with 40,000 blood samples

...n the next three years. With other diseases it has already been proven that the older body can no longer produce a sufficient amount of effective antibodies. 'We want to know in particular whether this is the case with infectious diseases where the viruses were discovered recently,' Oliver Schildgen says. ...

Soft-cell approach cuts animal tests

...ny industrial and environmental air pollutants are already known to have adverse health effects on the respiratory system of workers. Increasingly, new formulations are using tiny nanoparticles and ultrafine particulates in cosmetics, pharmaceuticals and petrochemical products. Little is known about their to...

Hotspots of mercury contamination identified in eastern North America

...at are highly sensitive to the element or that are already affected by it could raise the risk to people and wildlife that consume fish. There is reason to believe, however, that lowering emissions can reduce risk: an analysis of levels of mercury contamination over time in the Merrimack River watershed sugg...

Genes set scene for metastasis

...and overtake distant organs. A number of genes are already known to contribute to the spread of breast cancer cells to the lungs. Using genetic and pharmacological approaches, Joan Massagué, PhD, Chair of MSKCC's Cancer Biology and Genetics Program and a Howard Hughes Medical Institute Investigator, and ...

Nanotechnology meets biology and DNA finds its groove

...ible to science. Scientists, Schwartz explains, already know how to take DNA and stiffen it by removing salts from its chemical makeup. But confining the molecule and presenting it for analysis is laborious, engaging armies of lab techs worldwide to prepare DNA samples for their moment in the lab. "To ...

Synthetic peptide targets latent papilloma virus infections

...archers could some day help the millions of people already infected and at constant risk of genital warts and cancer. One study found that 75 percent of sexually active men and women under 50 have, or have had, an HPV infection, while 10,000 women annually develop cervical cancer, more than 90 percent of wh...

A genetic 'gang of 4' drives spread of breast cancer
