Cancer cells supported by normal cells in and near tumors

The targeting of interactions between cancer cells and their environment together with the traditional tactic of directly targeting cancer cells with drugs or radiation is an important new front in the fight against cancer. The study was conducted by two CSHL scientists from different disciplines who joined forces in the Laboratory’s tradition of collaborative research. Mikala Egeblad, Ph.D., is an expert in the analysis of interactions between cancer cells and normal cells, and Scott Powers, Ph.D., is an expert in applying genome-wide "big-picture" methods to the study of cancer…

Cross-country collaboration leads to new leukemia model

And after almost a decade of bicoastal collaboration, Emmanuelle Passegué, now a professor in the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research at the University of California, San Francisco, and Amy Wagers, a professor in Harvard’s Department of Stem Cell and Regenerative Biology, have the answer. They have found that cancer stem cells actively remodel the environment of the bone marrow, where blood cells are formed, so that it is hospitable only to diseased cells. This finding could influence the effectiveness of bone marrow transplants, currently the only cure for late-stage leukemia, but with a 25 percent success rate due to repopulation of residual cancer cells…

Human and canine lymphomas share molecular similarities, first large-scale comparison shows

A team of scientists from the University of North Carolina School of Medicine, North Carolina State University’s College of Veterinary Medicine and Duke University have conducted one of the first studies to directly compare canine and human B-cell lymphoma by examining molecular similarities and differences between the two species. The study was published June 19, 2013 online in the journal Cancer Research. Kristy Richards, MD, PhD, corresponding author, said, "Comparing the molecular similarities of lymphomas across species has allowed us to see what parts of lymphoma development and growth are evolutionarily conserved. This teaches us more about what components of human lymphoma biology are most fundamental and critical. …
