Researchers report the development of a technique that allows them to measure how well cancer drugs reach their targets inside the body. It shows individual cancer cells in a tumor in real time, revealing which cells interact with the drug and which cells the drug fails to reach, according to the scientists. In the future, the findings (“ Heterogeneity in tumor chromatin-doxorubicin binding revealed by in vivo fluorescence lifetime imaging confocal endomicroscopy ”), published in Nature Communications , could help clinicians decide the best course and delivery of treatment for cancer patients, note the researchers. “We present an approach to quantify drug–target engagement using in vivo fluorescence endomicroscopy, validated with in vitro measurements. Doxorubicin binding to chromatin changes the fluorescence lifetime of histone-GFP fusions that we measure in vivo at single-cell resolution using a confocal laparo/endomicroscope. We measure both intra- and inter-tumor heterogeneity in doxorubicin chromatin engagement in a ...

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
