Weight loss surgery was more effective than a low-fat diet at reversing the cancer-promoting effects of chronic obesity in mice, UNC Lineberger Comprehensive Cancer Center researchers report in a new study. The preliminary findings will be presented April 18 at the 2016 American Association of Cancer Research Annual Meeting in New Orleans.
Researchers with UNC Lineberger examined whether weight loss via four different diets was linked to reduced tumor growth in laboratory models of breast cancer. While tumor size did not differ between obese mice and obese mice that returned to a normal weight on a low-fat diet, they did find that obese mice that lost significant amounts of weight on three calorie-restricted diets had smaller tumors.
A UNC Lineberger-led study has identified genetic differences in tumors of African-Americans with the most common type of kidney cancer compared with whites. The researchers, led by senior author Dr. William "Billy" Kim, say the findings could help explain lower survival rates for African-Americans with clear cell renal cell carcinoma.
Researchers at UNC Lineberger and at other institutions developed a new potential treatment for acute myeloid leukemia. In the journal JCI Insight, they report that the compound MRX-2843 more than doubled the median days of survival in laboratory models with a drug-resistant form of the disease.
