Dual-action enzyme protects esophagus
May. 9, 2013—An antioxidant enzyme also functions as a tumor suppressor to limit cancer development in the esophagus.
Leukemia culprit’s cellular actions
Apr. 11, 2013—Overexpression of a gene that is a common culprit in leukemia induces stem cell-like features in T cells, which may enable the cells to become cancerous.
Nobel laureate Hartwell set for Discovery Lecture
Apr. 4, 2013—Nobel laureate Lee Hartwell, Ph.D., will deliver the next Flexner Discovery Lecture on Thursday, April 11.
Foundation lauds graduate student’s melanoma research
Mar. 28, 2013—Katherine Hutchinson, a third-year graduate student in Cancer Biology at Vanderbilt University, has won a $10,000 Research Scholar Award from the Joanna M. Nicolay Melanoma Foundation.
New drugs a good BET for brain cancer
Mar. 20, 2013—A novel class of drugs that target “BET” proteins may have broad utility for treating genetically diverse brain tumors.
Linking oxygen, iron and red blood cells
Feb. 6, 2013—The HIF oxygen-sensing pathway and its responses to low oxygen may be targeted for treatments of anemia and disorders of iron balance.
Brain tumor TIP reveals new target
Feb. 4, 2013—The protein TIP-1 appears to be a novel prognostic marker for glioblastoma and may be a good therapeutic target for disrupting tumor-driven blood vessel development.
Do-it-yourself repair in the kidney
Jan. 31, 2013—The kidney can mediate its own repair through proliferation of resident immune system cells.
A drug combo for ovarian cancer
Dec. 24, 2012—Combining another drug with platinum-based chemotherapies may be more effective against ovarian cancer.
Study tracks antioxidants’ role in prostate tumor growth
Nov. 15, 2012—Antioxidants promote cell growth in a mouse model of prostate cancer, Vanderbilt researchers report in the journal PLoS ONE. The findings provide insight into the recent controversy regarding antioxidants and prostate cancer prevention.
Stomach bug alters tumor suppressor
Oct. 23, 2012—The stomach bug Helicobacter pylori increases forms of a protein that promote tumor development, perhaps explaining how it elevates risk for gastric cancer.
Proteins help flip tumor’s invasive switch
Oct. 4, 2012—Vanderbilt investigators have identified how two key components of cancer's invasive "switch" — the series of signaling events that turn on a tumor cell’s invasive behavior — work together.
