Cancer Research: Mutations driving leukemia identified ♦Why cancer anemia treatment leads to tumor growth ♦ New test to predict relapse of testicular cancers

Scientists produce clearest-ever images of enzyme that plays key roles in aging, cancer The telomerase enzyme is known to play a significant role in aging and most cancers. Scientists have discovered several major new insights about this enzyme and they are now able to see the complex enzyme's subunits in much sharper resolution than ever before.
New test to predict relapse of testicular cancers Scientists have developed a new test to identify patients who are at risk of suffering a relapse from testicular cancer. Assessing just three features of a common kind of testicular cancer -- called non-seminomatous germ cell tumor -- can identify those at most at risk of relapse even where there is no evidence of tumor spread. The researchers believe the test could be used in the clinic to make decisions about which patients should be given chemotherapy.
Why cancer anemia treatment leads to tumor growth Scientists have shown why a drug widely used to treat chemotherapy-induced anemia in ovarian and breast cancer patients also may shorten survival times in some patients by inadvertently stimulating tumor growth.
Special class of T cells shown to both attack cancer cells and enlist other immune cells New insights about a subset of T cells has been shared by researchers, that suggest that they appear to both inhibit cancer growth and enhance the tumor-killing powers of other immune cells.
Mutations driving leukemia identified An international team of scientists has identified novel genes associated with chronic lymphocytic leukemia through the analysis of high-throughput sequencing data.
