Researchers Hope New Database Becomes Universal Cancer Genomics Tool

By Mike Martin for the Journal of the National Cancer Institute

Swiss scientists hope that a new online database called “arrayMap” will bring cancer genomics to the desktop, laptop, and tablet computers of pathologists and researchers everywhere.

The database combines genomic information from three sources: large repositories such as the NCBI Gene Expression Omnibus (GEO) and Cancer Genome Atlas (CGA); journal literature; and submissions from individual investigators. It incorporates more than 42,000 genomic copy number arrays—normal and abnormal DNA comparisons—from 195 cancer types.

“arrayMap includes a wider range of human cancer copy number samples than any single repository,” said principal investigator Michael Baudis, M.D. Ease of access, visualization, and data manipulation, he added, are top priorities in its ongoing development.

A product of the University of Zurich Institute for Molecular Life Sciences, where Baudis researches bioinformatics and oncogenomics, arrayMap illustrates the importance of copy number abnormalities (CNA)—dysfunctional DNA gains or losses that visibly lengthen or shorten certain chromosomes—in the diagnosis, staging, and treatment of various malignancies.

Semantic Web May Be Cancer Information’s Next Step Forward

By Mike Martin for the Journal of the National Cancer Institute

The next big thing on the Web—which World Wide Web inventor Tim Berners-Lee nicknamed “Web 3.0,” or the Semantic Web—may also be the next milestone in cancer information.

Already deployed in the U.S. census, the catalog of electronics retailer Best Buy, and Facebook pages, Semantic Web technology could give rise to “a killer app that allows the clinical oncologist to access, integrate, and analyze drug and genomics data, medical records, and other cancer-related information to enhance care and efficiency,” said Kei-Hoi Cheung, Ph.D., an associate professor at the Yale University School of Medicine Center for Medical Informatics.

Rewriting the Mathematics of Tumor Growth

By Mike Martin for the Journal of the National Cancer Institute

A new theory about tumor growth makes oncology look a little like cosmology. Just as the universe accelerates as it expands, tumors become malignant at an accelerating speed, according to a team of scientists who have been probing the mathematics of tumor growth.

About Mike Martin

A former senior science writer for United Press International, Mike Martin has written articles for Science, The Scientist, Harvard Magazine, MIT's Technology Review, and the Journal of the National Cancer Institute.

His clients include the Epilepsy Foundation, the Association of American Medical Colleges, the U.S. Department of Energy, and the California, Oregon, and Missouri university systems.

A member of the National Press Club and the National Association of Science Writers, Martin specializes in news about early-stage university and laboratory research.

He was a science journalism fellow at Duke University's National Evolutionary Synthesis Center in Fall 2011, where he completed two stories about Margie Profet -- one for the Journal of the National Cancer Institute and a second for Psychology Today. The latter piece led to a happy ending to her 8-year missing person story.

I’m writing from InkWell Management, a literary agency in New York. I recently had the pleasure of reading your exceptional article about Margie Profet. Have you considered book-writing? -- Nathaniel Jacks, InkWell Management, New York, NY on Margie Profet's Unfinished Symphony

I loved your piece on Margie Profet in Psychology Today. It was well done and well reported -- as interesting a piece on the nature of science, madness and genius as I’ve read. -- Daniel Levine, Partner, Levine Greenberg Literary Agency, on Margie Profet's Unfinished Symphony

Thanks for a great story. I really appreciate the job you are doing.

A very fine story, Mike. Thank you for this. -- Harvey Mansfield, William R. Kenan, Jr. Professor of Government, Harvard University, on Margie Profet's Unfinished Symphony

I knew Margie well during her time at the University of Washington. I agree with what is said near the end of the article: she was very innovative but was accepted, even embraced, by the scientific community for all of her innovation and oddness. I like that this article takes the optimistic view, implying that we will someday see her again. But I can't see her living a backwoods hermetic life. I fear that she is gone and I will forever miss her. -- George Lake, Professor of Theoretical Physics, Head, Computational Science Program Institute for Theoretical Physics, University of Zurich, Switzerland, on Margie Profet's Unfinished Symphony. [Note: Margie was found shortly after the story appeared].

Congratulations -- I think you did a great job. I really liked the way you explained how information can be fundamental, and the image about the big bang being like a supercomputer downloading information is brilliant. I'm going to quote you on that! -- Raphael Bousso, Professor of Physics, University of California Santa Barbara
