Genome-wide mouse study yields link to human leukemia

Thanks to a handful of very special mice, scientists have discovered a new tumor suppressor gene and a unique chemical signature implicated in the development of human leukemia, findings that open up a "treasure box" of opportunity and possibility, study authors say. Researchers in The Ohio State Univ...

...is case, the challenge was undertaken by a team of scientists ledby Gudrun Rappold, Ph.D., Professor of Human Genetics at the Universityof Heidelberg in Germany. Their manuscript describing this work,published online today and in the February print issue of GenomeResearch (www.genome.org), presents the sequenci...

Live Recombinant Adenovirus Vaccine Technique Explored

... which behaves similarly to HPV. Research by other scientists showed that a vaccine consisting of recombinant HPV major capsid protein (L1) provides effective immunity to HPV infection. Dr. Ketner and his colleagues theorized that a live recombinant adenovirus could be made to express L1 as the virus replicated...

Gene therapy converts dead bone graft to new, living tissue

... the Musculoskeletal Transplant Foundation. Other scientists have attempted to invoke a similar reaction in dead bone by infusing tissue-growing proteins directly into the bone. This has proven successful for the small bone transplants used in spinal fusion, but not for larger grafts, because the proteins' eff...

Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

For the first time, scientists have foundthat bacteria can use a Sonar-like system to spot other cells (eithernormal body cells or other bacteria) and target them for destruction.Reported in the December 24 issue of Science, this finding explains howsome bacteria know when to prod...
