Abstract：
:As the analysis of apoptosis is of interest in many basic and clinically oriented investigations, we intend to give a brief overview on the recently most-used methods for detection of apoptotic cells, including the study of morphology, analysis of DNA degradation, DNA end-labeling techniques, flow cytometric analysis, and nuclease assays. Features and advantages of the different methods are discussed.

We hypothesized that inducible overexpression of clock genes (cry, per, tim, cyc and Clk) in the nervous system can improve healthspan of D. melanogaster. We studied the lifes...
