Functional Imaging of Cancer Mitochondria with Multiphoton Confocal Microscopy

  • Maximizing the possibility of effectively treating cancer requires timely assessment of its aggressiveness and susceptibility to drug intervention. During cancer surgery, the “fast biopsy” is a commonly employed technique to assess a tumor’s invasiveness and guide surgery. Unfortunately, it is of limited value in predicting a tumor’s metastatic potential and susceptibility to drug treatment. However, certain functional biomarkers, like mitochondrial membrane potential and reactive oxygen species, which may be indicative of both aggressiveness and drug susceptibility, can be measured in “real time” using confocal microscopy. To this end, theoretical and practical aspects of functional confocal imaging are presented as a general overview and in conjunction with a clinical trial treating glioblastoma multiforme (GBM) using the metabolic modulating drug DCA. Functional imaging of biopsies from 40 GBM patients, various cancer and normal cell lines validated confocal microscopy as a tool assessing functional biomarkers and the effectiveness of DCA treatment.
