E-mail: mettemj@sund.ku.dk Introduction For the evaluation of impact in animal studies throughout preclinical improvement of new anticancer agents, reduction in tumor volume is definitely the most normally applied criterion for efficacy. Nevertheless, the time until tumor shrinkage might be long and it needs repeated tumor volume measurements a number of occasions weekly to show impact. Non-invasive molecular imaging like positron emission tomography makes it possible for for biological processes to become visualized and quantified non-invasively more than time. A non-invasive method to detect early biological response following anticancer treatment could be beneficial in anticancer drug development to distinguish powerful from non-effective drugs prior to adjustments in tumor volume become evident. Increased cell proliferation is among the principal capabilities of cancer. Much investigation focuses on the non-invasive visualization of cell proliferation, which may be utilized to define a biological response to therapy early for the duration of the course of therapy. 39-deoxy-39fluorothymidine is made use of as a PET tracer for visualization of cell proliferation. 18F-FLT is often a thymidine analogue and consequently a substrate from the DNA synthetic pathway. When taken up in cells 18F-FLT is phosphorylated by thymidine kinase-1, which leads to intracellular trapping. TK1 activity is tightly cell cycle regulated and is mainly expressed September 2010 | Volume 5 | Problem 9 | e12965 FLT-PET and Exp. Chemotherapy during the S-phase of your cell cycle; consequently, it is assumed to reflect the level of proliferating cells. 18F-FLT uptake is positively correlated with cell growth and TK1 activity. Various studies have showed a correlation in between 18F-FLT uptake and tumor cell proliferation both in cancer xenografts in mice and human tumor s
