Agent prevents prostate cancer growth, spread in animal studies — ScienceDaily

Published online Dec. 5 in PLOS ONE, the scientists say the agent, YK-4-279, is the first drug targeted at the chromosomal translocations found in about half of prostate cancer cells. These translocations occur when two normal genes break off from a chromosome and fuse together in a new location. …

Modeling tumor dormancy: What makes a tumor switch from dormant to malignant?

A new computational model developed in the laboratory of Salvatore Torquato, a Professor of Chemistry at Princeton University, may help illuminate the conditions surrounding tumor dormancy and the switch to a malignant state. Published today in PLOS ONE, the so-called cellular automaton model simulated various scenarios of tumor growth leading to tumor suppression, dormancy or proliferation. “The power of the model is that it lets people to test medically realistic scenarios,” Torquato said. In future collaborations, these scenarios could be engineered in laboratory experiments and the observed outcomes could be used to calibrate the model. …

Triple therapy revs up immune system against common brain tumor

Mice with implanted, mouse-derived glioblastoma cells lived an average of 67 days after the triple therapy, compared with mice that lasted 24 days when they received only the two immunotherapies. Half of the mice who received the triple therapy lived 100 days or more and were protected against further tumors when new cancer cells were re-injected under the animals’ skins. The combination treatment described in the July 11 issue of PLOS One consists of highly focused radiation therapy targeted specifically to the tumor and strategies that lift the brakes and activate the body’s immune system, allowing anti-cancer drugs to attack the tumor…
