A new method of delivering chemotherapy to cancer patients without incurring side effects such as hair loss and vomiting is being developed.

Mayo Clinic researchers report that the expression of two novel genes within the tumors of women with early stage breast cancer may allow identification of women who are and are not at risk for early relapse or cancer-related death. Results of the study are published in the April 1 issue of Clinical Cancer Research.

Scientists from The University of Tokyo announce today that gibbons, arboreal primates that inhabit the jungles of Southeast Asia, do not carry a major obesity gene that is present in the genomes of all other primates, including humans. This omission is due to a genetic mis-shuffling event that occurred approximately 25 million years ago. Their results are reported in the April issue of the scientific journal Genome Research.

Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice. Their findings describe the first documented cases of human infection with a retrovirus that is native to rodents.

The journal PLoS Genetics has published the findings of a team of scientists at the nonprofit Boston Biomedical Research Institute that provides a whole genome analysis of the protein kinases from a scientifically valuable model organism known as Dictyostelium.

University of Cincinnati (UC) surgeons have developed a new, minimally invasive method for repairing a common and deadly form of aortic injury--an advance that could help reduce the number of deaths caused by auto accidents and major falls.
