Title of Doctorate thesisInterrelation between lifespan, fecundity and metabolism

Specialty: 03.00.04 Biochemistry

Advisor: Prof., D.Sci. Volodymyr Lushchak

Annotation. Nutrition is an important physiological train for every alive organism. It influences the lifespan, metabolism, reproduction and others. However, these factors together with hormonal regulation affect nutrition to form the network of regulatory mechanism to form proper response to macronutrient availability. Unbalanced nutrition may cause the changes in metabolism to induce development of complication like obesity, diabetes or cancer. The aim of the work is to study the molecular mechanisms to regulate nutrition, lifespan and metabolism in response to diet. Additionally, evolutional aspects of adaptation to unbalanced diet and the role of TOR and IIS/IGF pathways will be analyzed.

Maria Bayliak, PhD

Title of Doctorate thesis: Using of natural substances for enhancement of adaptive potential and retardation of aging

Specialty: 03.00.04 Biochemistry

Advisor: Prof., D.Sci. Volodymyr Lushchak

Annotation. The dissertation is devoted to the study of stress-protective and geroprotective properties of plant derived substances (quercetin and Rhodiola rosea extracts), as well as cellular metabolites, alpha-ketoglutarate and arginine. The common feature of all the substances studied is their ability to affect redox processes. Therefore, we elucidated the role of antioxidant and prooxidant mechanisms of the substances in modulation of adaptive potential and lifespan of model organisms, yeast Saccharomyces cerevisiae and fruit fly Drosophila melanogaster. In general, in vitro experiments and experiments with model organisms, yeast S. cerevisiae and fruit fly D. melanogaster, showed that the studied natural substances can act as antioxidants or, on the contrary, stimulate the production of ROS depending on the conditions. It was found, that due to their pro-oxidant properties, natural substances were able to increase adaptive potential and prolong lifespan of yeasts and fruit flies and as well as they can exhibit toxic effects.
