ВВЕДЕНИЕВ настоящее время активно исследуется влияние на продолжительность жизни (ПЖ) различных экологических факторов -температуры (Helfand, Rogina, 2003;Huang et al., 2004), качества пищи (Helfand, Rogina 2003;Cheng et al., 2005;Partridge et al., 2005), ионизирующей радиации (Моска-лев, 2004Sasaki, Fukuda, 2006;Moskalev, 2007;Moskalev et al., 2008), ведется поиск генетических механизмов их влияния на скорость старения ор-ганизма. В то же время работы, касающиеся проблем генетического контроля влияния на ПЖ различных режимов освещения, крайне немногочисленны.Известно, что искусственное увеличение длины светового дня уменьшает ПЖ Drosophila melanogaster и мышей, тогда как его укорочение увеличива-ет ее (Москалев и др
It was investigated the combined effects of different light regimes (round-the-clock lighting or darkening) and antioxidant melatonin on Drosophila melanogaster life span of wild type strain Canton-S,mutant strain with defect of red-ox system (Sod) and mu tant strain with disturbance of excision DNA repair (mus210). It was revealed, that maintenance of Drosophila imago at round-the-clock lighting leads to decrease of mean and/or maximum life span with compare to being at darkening. Adding of melatonin to Drosophila meal induces the geroprotector effects, mainly, in dark conditions. The effects mentioned above were most expressed in strain with mutation of Sod. All effects have revealed in both sexes. The data analysis has shown that mechanisms of different light regimes and melatonin influ ence on life span are rather different.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
