Özet

Fission yeast is the ideal model organism for studying telomere maintenance in higher eukaryotes. Telomere length has been directly correlated with life expectancy and the onset of aging-related diseases in mammals. In this study, we developed a novel simple, and reproducible method to measure the telomere length, by investigating the effect of caffeine and cisplatin on the telomere length in fission yeast. Hydroxyurea-synchronized fission yeast cells were exposed to 62 μM cisplatin and 8.67 mM caffeine treatments for 2 h, then their telomere lengths were evaluated with two different methods. First, the quantitative polymerase chain reaction (qPCR) assay was used as a confirmative method, where telomere length was determined relative to a single-copy gene in the genome. Second, the newly developed method standard polymerase chain reaction (PCR)/ImageJ assay assessed the telomere length based on the amplified PCR band intensity using a set of telomere primers, reflecting telomeric sequence availability in the genome. Both methods show a significant decrease and a notable telomere lengthening in response to cisplatin and caffeine treatments, respectively. The finding supports the accuracy and productivity of the standard PCR/ImageJ assay as it can serve as a quick screening tool to study the effect of suspected chemotherapeutic and antiaging drugs on telomere length in fission yeast.
