The discovery that prostate cancer gene 3 (PCA3) is overexpressed in malignant prostate cells has led to the development of a PCA3 urine test for prostate cancer. In this Review, the authors discuss the molecular marker PCA3 and its application in the diagnosis of prostate cancer and use as a prognostic indicator in men with prostate cancer.

Emphysematous pyelonephritis is a severe, necrotizing, renal parenchymal infection that is characterized by the production of intraparenchymal gas. Predominantly affecting female diabetics, the presentation of this disorder has changed over the past 25 years. A more conservative approach to treatment is now recommended.

Glutathione S-transferases protect cells from toxic electrophilic compounds, including potential carcinogens, by catalyzing their conjugation to glutathione. These enzymes are found in both kidney and urothelial tissue. In this Review, Simic and colleagues discuss the relationships between enzyme polymorphism, altered expression, susceptibility to kidney and bladder tumors, and resistance to chemotherapy.
