Results from Berkeley Lab and University of Copenhagen Collaboration Contradict Current Views on Cancer Stem Cells

New findings in breast cancer research by an international team of scientists contradict the prevailing belief that only basal-like cells with stem cell qualities can form invasive tumors. Research led by Ole William Petersen at the University of Copenhagen (CU) and Mina Bissell of the Lawrence Berkeley National Laboratory (Berkeley Lab) and has shown that luminal-like cells with no detectable stem cell qualities can generate larger tumors than their basal-like counterparts. This may hold important implications for the diagnosis and the treatment of breast cancer as well as future personalized cancer medicine. (more…)

Deficiencies compound over time, researchers say

Evolutionary biologists at the University of Toronto have found that individuals with low-quality genes may produce offspring with even more inferior chromosomes, possibly leading to the extinction of certain species over generations. (more…)

People who received frequent dental X-rays in the past, before dosages were lowered, have an increased risk of developing a meningioma, the most common and potentially debilitating type of non-cancerous brain tumor, a new study led by the Yale School of Public Health has found. The study is published online in Cancer, a journal of the American Cancer Society. (more…)
