Using LINCS and other Big Data to Find New Cancer Treatments

A new study using computational tools to combine multiple sets of previously generated biomedical big data has identified drugs that can be repurposed to fight cancer. Dr. Bin Chen, a Big Data to Knowledge (BD2K) Mentored Career Development Awardee, and colleagues took advantage of multiple existing data sets, including the NIH Common Fund’s Library of Integrated Network-based Cellular Signatures (LINCS) L1000 data set and the National Cancer Institute’s The Cancer Genome Atlas (TCGA) data set to generate a list of potential drugs predicted to inhibit the growth of liver cancer cells. Dr. Chen and colleagues compared the global cellular changes between normal and cancerous liver cells in the TCGA data set with changes caused by treating cells with a panel of 12,442 distinct chemical compounds in the LINCS data sets. They tested the hypothesis that compounds causing inverse changes to those seen when a cell becomes cancerous would be strong candidates for treating cancer. Using this approach, four compounds were selected that had the potential to reverse the changes seen in liver cancer patients. When these compounds were tested against liver cancer cell lines grown in the laboratory, all four inhibited the growth of these cells. The most potent of these drugs was also tested in a mouse liver cancer model and was shown to reduce the size of tumors. This drug (pyrvinium pamoate), which has been previously FDA approved to treat pinworm infections, will require further experimentation to determine if it can be repurposed to treat liver cancer in humans.

The growing number of large, robust experimental data sets in biomedical research offers unprecedented opportunities for new discoveries using computational approaches, which is a continuing goal of the BD2K program. This study, also demonstrates the power of using the LINCS data sets to discover novel therapeutics by focusing on global cellular changes instead of a singular molecular target. Similar approaches have the potential to yield candidate drugs for repurposing to treat a wide spectrum of diseases.

The ENIGMA Consortium Maps the Brain’s Gray Matter in People with Bipolar Disorder

Bipolar Brain ImagingBipolar disorder, which affects 1-3% of the adult population, is a disorder of the brain that results in extreme shifts in mood from periods being extremely “up” (manic episodes) to extremely “down” (depressive episodes). Despite bipolar disorder being a common disease, not much is known about the biological mechanisms that lead to it.

In the largest ever imaging study of bipolar disorder, the ENIGMA consortium, a BD2K Center of Excellence, found that the gray matter in particular sections of the brain in people with bipolar disorder is thinner than in healthy individuals. Gray matter covers the surface of the brain and is where the bodies of the brain’s nerve cells are located. This study, which was a collaboration between 79 institutions worldwide, analyzed the MRI scans of 6503 individuals in order to control for variables such as age, sex, prescribed medications, and duration and type of disease. The researchers found that the thinning effect was greater the longer people had the disease and some of the medications used to treat bipolar disorder seemed to protect against thinning. The results of this study could be used to evaluate the effectiveness of treatments and aid in early detection and intervention.
