Cancer Research: Virus in cattle linked to human breast cancer ♦ Genetic mechanism for cancer progression discovered ♦ Keeping one step ahead of cancer cells

Genetic mechanism for cancer progression discovered Genetics researchers have identified a novel long non-coding RNA, dubbed DACOR1, that has the potential to stymie the growth of tumor cells in the second-most deadly form of cancer in the US -- colorectal cancer.
Drug resistance in cancer patients linked to oxygen-bearing molecules in body Increased levels of certain chemically reactive, oxygen-containing molecules in the body can cause patients to become resistant to cancer drugs such as chemotherapy.
Mediterranean diet plus olive oil associated with reduced breast cancer risk Eating a Mediterranean diet supplemented with extra virgin olive oil was associated with a relatively lower risk of breast cancer in a study of women in Spain.
Virus in cattle linked to human breast cancer For the first time, researchers have established a link between infection with the bovine leukemia virus and human breast cancer. Researchers analyzed breast tissue from 239 women, comparing samples from women who had breast cancer with women who had no history of the disease for the presence of bovine leukemia virus (BLV). They found that 59 percent of breast cancer samples had evidence of exposure to BLV, as determined by the presence of viral DNA.

Keeping one step ahead of cancer cells BRD4 inhibitors are among the most promising new agents in cancer therapy that are currently evaluated in clinical trials. In a new study, a team of researchers reveals how leukemia cells can evade the deadly effects of BRD4 inhibition. Understanding this adaptation process could aid the development of sequential therapies to outsmart resistant leukemias.
