“Redox Imaging” to Distinguish Cells with Different Proliferative Indexes: Superoxide, Hydroperoxides, and Their Ratio as Potential Biomarkers

and oxidative capacities, confirmed by conventional analytical tests. The data suggest that cancer cells and noncancer cells are characterized by a completely different redox status. This can be ... capacity of the cancer cells compared to the normal cells. The data were verified by conventional analytical tests, demonstrating that normal colon epithelial cells have a higher reducing capacity and lower

Protein Analytical Assays for Diagnosing, Monitoring, and Choosing Treatment for Cancer Patients

Cancer treatment is often hindered by inadequate methods for diagnosing the disease or insufficient predictive capacity regarding therapeutic efficacy. Targeted cancer treatments, including Bcr-Abl and EGFR kinase inhibitors, have increased survival for some cancer patients but are ineffective in other patients. In addition, many patients who initially respond to targeted...
