Can thermodynamics help us better understand human cancers?

When the “war on cancer” was declared with the signing of the National Cancer Act in 1971, identifying potential physical traits, or biomarkers, that would allow doctors to detect the disease early on was a significant goal. To this day, progress in the battle against cancer depends on understanding the underlying causes and molecular mechanisms of the disease.

In a new study, UCLA researchers analyzed the gene-expression profiles of more than 2,000 patients and were able to identify cancer-specific gene signatures for breast, lung, prostate and ovarian cancers. The study applied an innovative approach to gene-array analysis known as “surprisal analysis,” which uses the principles of thermodynamics — the study of the relationship between different forms of energy — to understand cellular processes in cancer.
