Understanding how cancer cells shift into high gear—what makes them become more aggressive and unresponsive to treatment—is a key concern of cancer researchers. A new study reveals how this escalation occurs in the most common form of kidney cancer: clear cell renal cell carcinoma (ccRCC). The study shows that ccRCC tumors acquire specific mutations that encourage uncontrollable growth and shifts in energy use and production [1].

Conducted by researchers in the NIH-led The Cancer Genome Atlas (TCGA) Research Network, the study compared more than 400 ccRCC tumors from individual patients with healthy tissue samples from the same patients. Researchers were looking for differences in the gene activity and proteins in healthy vs. tumor tissue.
