Origins of colorectal cancer tumor cells traced

The scientists employed a “Big Bang” model of human colorectal cancer growth similar to the theory that the universe started from a single point and exploded outward. The team was led by Keck faculty researchers Darryl Shibata, M.D., professor of pathology, Keck School of Medicine of USC and Christina Curtis, Ph.D., M.Sc., assistant professor of medicine and genetics at Stanford University and adjunct assistant professor, department of Preventive Medicine, Keck School of Medicine of USC. “It’s like going back in time,” said Shibata. …

War metaphors for cancer hurt certain prevention behaviors

But a new University of Michigan study indicates that using those words can have an unintended negative effect. David Hauser, a U-M doctoral student in psychology, and colleague Norbert Schwarz of the University of Southern California, found in three studies that exposure to metaphoric language relating cancer to an enemy significantly lessens the extent to which people consider cancer-prevention behaviors. …

Researchers engineer ‘smart bomb’ to attack childhood leukemia

In a November study in the new peer-reviewed, open-access journal EBioMedicine, they describe how this approach could eventually prove lifesaving for children who have relapsed after initial chemotherapy and face a less than 20 percent chance of long-term survival. “We knew that we could kill chemotherapy-resistant leukemia cells if we only knew what made them so resistant…

Clear new evidence for mind-body connection demonstrated in study — ScienceDaily

A group working out of Alberta Health Services’ Tom Baker Cancer Centre and the University of Calgary Department of Oncology has demonstrated that telomeres — protein complexes at the end of chromosomes — maintain their length in breast cancer survivors who practise meditation or are involved in support groups, while they shorten in a comparison group without any intervention. Although the disease-regulating properties of telomeres aren’t fully understood, shortened telomeres are associated with several disease states, as well as cell aging, while longer telomeres are thought to be protective against disease. “We already know that psychosocial interventions like mindfulness meditation will help you feel better mentally, but now for the first time we have evidence that they can also influence key aspects of your biology,” says Dr. Linda E. …

Shingles vaccine remains effective after chemotherapy

Researchers examined the electronic health records of more than 21,000 Kaiser Permanente patients in Southern California who were 60 years of age and older and received chemotherapy between January 2007 and December 2012. Researchers found that those patients who were previously vaccinated with zoster vaccine were 42 percent less likely to develop shingles following chemotherapy. In addition, no vaccinated patients underwent hospitalization for shingles, while six unvaccinated patients were hospitalized with the disease, according to the study…

Genetic mutations linked to salivary gland tumors

The research, recently published online ahead of print by the Proceedings of the National Academy of Sciences, shows that a pair of proteins joined together by a genetic mutation — known as CRTC1/MAML2 (C1/M2) — work with MYC, a protein commonly associated with other cancers, to promote the oral cancer’s growth and spread. “This research provides new insights into the molecular mechanisms of these malignances and points to a new direction for potential therapies,” says TSRI biologist Michael Conkright, PhD, who led the study…
