Lung Cancer

A team of researchers has found that the expression pattern of certain microRNAs, or miRNAs, may predict tumor aggressiveness in some patients with lung cancer. These findings indicate that miRNAs may represent a new class of diagnostic and prognostic tools for lung cancer. The study results appear in the March 13, 2006, issue of Cancer Cell.

miRNAs are small segments of genetic material called ribonucleic acid, or RNA, and are thought to control gene expression. Their actions could change the expression of cancer-related genes within a cell and lead to malignancies.

The researchers identified two miRNAs
