Abstract

Oxidative stress contributes substantially to urothelial carcinogenesis. Its extent can be assessed by measurements of reactive species (mainly reactive oxygen species (ROS)), oxidatively modified damage products, and levels of various antioxidants. We presented herein the methods for the measurement of protein carbonyl content and intracellular production of ROS. Protein carbonyl is the most commonly used indicator of protein oxidation because it is early formed and relatively stable under oxidative stress. Determination of protein carbonyl relies on the derivatization of carbonyl groups (aldehydes: R-CHO and ketones: R-CO-R) with 2,4-dinitrophenylhydrazine (DNPH) under strongly acidic conditions to yield stable dinitrophenyl (DNP) hydrazones. Absorbance of the DNP hydrazones at 370–375 nm is proportional to the content of carbonyl groups. To report the protein carbonyl content, it is usually normalized by total proteins. Detection of intracellular ROS production is based on oxidation of 2′,7′-dichlorofluorescein-diacetate (DCFH-DA) by ROS to produce the highly fluorescent 2′,7′-dichlorofluorescein (DCF). Fluorescent intensity measured at 480 nm excitation and 535 nm emission is directly proportional to the amount of ROS generated.
