Study Finds Potential New Biomarker for Cancer Patient Prognosis

Berkeley Lab researchers identified 14 genes regulating genome integrity that were consistently overexpressed in a wide variety of cancers. They then created a scoring system based upon the degree of gene overexpression. For several major types of cancer, including breast and lung cancers, the higher the score, the worse the prognosis. Perhaps more importantly, scores could accurately predict patient response to specific cancer treatments.

The researchers said the findings, published in the journalĀ Nature Communications, could lead to a new biomarker for the early stages of tumor development. The information obtained could help reduce the use of cancer treatments that have a low probability of helping.

As the co-authors of the study, Jian-Hua Mao (BBDS) and Wei Zhu (Cellular Biomedicine Group in Shanghai) provided critical expertise in bioinformatics for this research. (Related news link)
