Tools for exploring ‘omics’ data

Thursday, May 21st, 2015

Advances in technology have generated vast amounts of “omics” data: genomic, epigenomic, transcriptomic, proteomic and metabolomic changes for all types of specimens. Bridging the gap between data generation and investigators’ ability to retrieve and interpret data is essential to realize the biological and clinical value of this wealth of information. Bing Zhang, Ph.D., and colleagues […]

VICC research efforts in spotlight at AACR conference

Thursday, April 30th, 2015

Adding an investigational drug to an already approved estrogen blocking therapy appears to be safe and provided clinical benefit for some postmenopausal women with estrogen-positive breast cancer. The research led by Ingrid Mayer, M.D., associate professor of Medicine and clinical director of the Breast Cancer Program at Vanderbilt-Ingram Cancer Center (VICC), was selected for the […]

Cancer signaling pathway blocker

Friday, April 10th, 2015

Researchers at Vanderbilt University have discovered a new way to inhibit Hedgehog (Hh) signaling, an important regulatory pathway for vertebrate development – and cancer. Abnormal regulation of this pathway leads to several human malignancies, including small cell lung cancer and pancreatic cancer, and therefore it is a potential drug target for cancer. Small molecules have […]

Micelle “packets” deliver cancer drugs

Friday, April 10th, 2015

Small interfering RNA (siRNA) molecules can suppress tumor growth and target cells otherwise untreatable by conventional therapeutics, but targeted, intracellular delivery is a significant limitation to siRNA translation. To deliver the siRNA molecules into tumor cells, researchers have packaged them in micelles that express folic acid, which is internalized by cancer cells that overexpress folate […]

New driver behind lung cancer progression

Thursday, April 2nd, 2015

Vanderbilt-Ingram Cancer Center investigators have identified the mechanisms used by a gene and its binding protein to drive tumor growth in several forms of cancer, including non-small cell lung cancer. In a report published online recently in the Proceedings of the National Academy of Sciences (PNAS), first author Jun Qian, Ph.D., lead investigator Pierre Massion, M.D., […]

‘Docking stations’ on chromosomes new anti-cancer target

Thursday, March 26th, 2015

Vanderbilt University researchers have discovered a cleft in a chromosome-binding protein that may hold the key to stopping most cancers in their tracks. The protein, WDR5, is a “docking station” for a family of transcription factors called MYC that is overexpressed in the majority of malignancies and which contributes to an estimated 100,000 cancer-related deaths […]

Mutations may predict melanoma response to immunotherapies

Thursday, March 12th, 2015

Melanoma patients whose tumors test positive for mutations in the NRAS gene were more likely to benefit from new immunotherapy drugs, according to a new study led by Vanderbilt-Ingram Cancer Center (VICC) investigators. Douglas Johnson, M.D., assistant professor of Medicine, and Christine Lovly, M.D., Ph.D., assistant professor of Medicine and Cancer Biology, are co-first authors […]

Cancer survival improvements vary by age, race

Thursday, February 26th, 2015

Improvements in cancer diagnosis and treatment have led to longer survival for most cancer patients in the United States. However, the improvement in survival was substantially greater among younger patients and those who are white in most of the cancers studied, according to new research by Vanderbilt University investigators. The study was published online recently […]

Gene profile predicts metastasis

Thursday, February 12th, 2015

Gene expression profiling has been applied to predict metastatic recurrence, the leading cause of deaths in patients with colorectal carcinoma. However, the biological mechanism is not completely understood, driving poor clinical outcomes. To address this issue, Dan Beauchamp, M.D., Bing Zhang, Ph.D., and colleagues analyzed the 11 human microarray datasets from 1,295 tumor specimens as […]

Yoga therapy for cancer patients studied

Thursday, January 29th, 2015

Cancer is bad enough. But cancer patients who receive surgery, radiation and chemotherapy may suffer from side effects that run from irritating to crippling — problems that are postural, musculoskeletal and respiratory, along with lowered self-esteem. Many suffer from lymphedema, swelling caused by retained fluid in a compromised lymphatic system. One answer may be the […]
