INVOLVEMENT OF CATALASE IN SACCHAROMYCES CEREVISIAE HORMETIC RESPONSE TO HYDROGEN PEROXIDE

By Ruslana Vasylkovska, Nadia Burdylyuk and Halyna Semchyshyn

Abstract

In this study, we investigated the relationship between catalase activity and H<sub>2</sub>O<sub>2</sub>-induced hormetic response in budding yeast <em>S. cerevisiae</em>. In general, our data suggest that: (<em>i</em>) hydrogen peroxide induces hormesis in a concentration- and time-dependent manner; and (<em>ii</em>) the effect of hydrogen peroxide on yeast colony growth positively correlates with the activity of catalase that suggests the enzyme involvement in overall H<sub>2</sub>O<sub>2</sub>-induced stress response and hormetic response in yeast
