A team of Ontario researchers has identified a six-gene signature that can help predict non-small cell lung cancer outcomes — and uncovered evidence that there may be thousands of alternative prognostic signatures for the disease.
Small (and not-so-small) noncoding RNAs have thrown a spanner in the works of understanding genome function. We take a look at the major questions brought about by micro-RNA, Piwi-interacting RNA, and more.
Trey Ideker says the real value of gene expression data is determining which pathways are critical to a particular disease. In his cancer studies, the pathway-based approach could become a new kind of biomarker.
