Insects provide tractable models for enhancing our understanding of the physiological and cellular processes that enable survival at extreme low temperatures. They possess three main strategies to survive cold: freeze tolerance, avoidance or cryoprotective dehydration, which latter method is exploited by model species, Arctic springtail Megaphorura arctica, formerly Onychiurus arcticus (Tullberg 1876). The mechanisms underlying dehydration have been well characterised in M. arctica date this...
Abstract Honey bee health has been an important and ongoing topic in recent years. is also model organism for aging studies. Polyamines, putrescine, spermidine spermine, are ubiquitous polycations, involved a wide range of cellular processes such as cell growth, gene regulation, immunity, regulation lifespan. Spermidine, named longevity elixir, most analysed the context aging. One several proposed mechanisms behind actions antioxidative activity. In present study we showed that dietary...
The honey bee (Apis mellifera L.), as an eusocial insect species, is important model organism in research focusing on ageing and longevity, due to prominent seasonal lifespan plasticity within the worker caste (summer winter bees). In this study, we employed a screening approach evaluate several molecular parameters, providing comprehensive insights into antioxidative (superoxide dismutase catalase activity, reduced glutathione sulfhydryl group content, total capacity), detoxifying...
Ice, snow and temperatures of -14°C are conditions which most animals would find difficult, if not impossible, to survive in. However this exactly describes the Arctic winter, springtail Onychiurus arcticus regularly survives these extreme re-emerges in spring. It is able do by reducing amount water its body almost zero: a process that called "protective dehydration". The aim project was generate clones sequence data form ESTs provide platform for future molecular characterisation processes...
Understanding the cellular stress response in honey bees will significantly contribute to their conservation. The aim of this study was analyze antioxidative enzymes superoxide dismutase and catalase related presence toxic metals different habitats. Three locations were selected: (i) Tunovo on mountain Golija, as control area, without industry large human impact, (ii) Belgrade urban (iii) Zajača, mining industrial zone. Our results showed that concentrations lead (Pb) whole body vary...
The European corn borer, Ostrinia nubilalis Hbn., is a pest Lepidopteran species whose larvae overwinter by entering diapause, gradually becoming cold-hardy. To investigate metabolic changes during cold hardening, activities of four enzymes - citrate synthase (CS), lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate (AST) were measured in whole-body homogenates pupae, non-diapausing diapausing acclimated to 5 °C, -3 °C -16 °C. highest CS activity was detected larvae,...
Abstract The recent decline in managed honey bee populations, A pis mellifera L. ( H ymenoptera: pidae), has caused scientific, ecological, and economic concern. Research into the formation of reactive oxygen species ROS ), antioxidative defense mechanisms, oxidative stress can contribute to our understanding survival conservation this species. Activities superoxide dismutase SOD catalase CAT glutathione S ‐transferase GST ) enzymes together with levels malondialdehyde MDA were measured...
Abstract Metallothioneins are ubiquitous proteins important in metal homeostasis and detoxification. However, they have not previously been identified honey bees or other Hymenoptera, where metallothioneins could be of ecophysiological ecotoxicological significance. Better understanding the molecular responses to stress induced by toxic metals contribute bee conservation. In addition, metallothionein represent a biomarker for monitoring environmental quality. Here we identify characterize...
Cold hardiness in the Arctic Collembola Megaphorura arctica (Tullberg), formerly Onychiurus arcticus , has been subject of extensive studies over last decade. This species employs an unusual strategy known as cryoprotective dehydration to survive winter temperatures low −25 °C. To expand knowledge M. present study investigates how a reduction ambient temperature affects fatty acid composition total body lipid content along with polar (mainly membrane phospholipids) and nonpolar...
Nuclear magnetic resonance (NMR) spectroscopy is powerful metabolomic technique which allows overview of numerous compounds simultaneously. In this study, 1H-NMR -based approach was used to investigate entering into diapause and cold hardiness diapausing larvae European corn borer (Ostrinia nubilalis). Obvious relationship between species poorly understood, especially on level. Therefore, we have compared the patterns in polar extract hemolymph non-diapausing O. nubilalis. Results shown that...
