Lateral thinking produces first map of gene transmission

...curs in bacteria through methods such as bacterial viruses and direct contact between cells. "The idea of lateral genetic transfer has been around for a few years, but what was missing was a good, hard, rigorous look at it," Professor Ragan said. "Previous studies have either been small scale, or used st...

Common viruses may cause cancer

...ons can also cause cell fusion, but cells fused by viruses are widely considered to be harmless because they ... a recent study, however, cell fusion triggered by viruses is a possible contributing factor in the development of human cancer. The study also raises concerns...

Biologists discover new pathway into plant cells

...s a toxin to kill the cell. It had been known that viruses and bacteria can penetrate cell wall barriers and disrupt plant cells, but never before has a protein been found that could do this by itself. When more research is done, this may provide a new tool to penetrate plant cells and possibly manipulate t...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...oting results. That's interesting, because the two viruses are so different --HPV is a DNA virus, while hepatitis C is composed of RNA." Understanding just how hepatitis C infection leads to the development of cancer is of critical importance, Lemon said. With no one "silver bullet" cure for hepatitis C on ...

UCLA scientists discover immune response to HIV differs, even in identical twins

Yale scientists decipher 'wiring pattern' of cell signaling networks

...anisms as diverse as man, mouse, baker's yeast and viruses has been generated. While genomic DNA is the blueprint, the encoded proteins are the products that carry out the complex biological functions of cells. Although scientists can predict from the DNA what proteins are in the proteome of an organism, thi...

Infant transplant patients resist infections that kill adult AIDS patients

Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

...ter is marked by the outbreak of flu caused by new viruses that the human immune system doesn't recognize. The new Reactome influenza database outlines a typical virus life cycle, which will be updated as more research becomes available. "In the future, the goal is to build out all of the host-pathogen rea...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

...mophilia patients for years, but problems with the viruses typically used to transport needed genes to their target destinations have stymied their success, Fletcher said. Researchers usually hide corrective genes inside viruses, which then infect cells. Without the virus to act as a key, the gene would be ...
