Transcription factors Atf1 and Sty1 promote stress tolerance under nitrosative stress in Schizosaccharomyces pombe
چکیده انگلیسی

Nitric Oxide (NO) and its associated reactive nitrogen species (RNS) produce nitrosative stress under various pathophysiological conditions in eukaryotes. The fission yeast Schizosaccharomyces pombe regulates stress response mainly through the Sty1-Atf1 MAP Kinase pathway. The present study deals with the role of transcription factor Atf1 and Sty1 in S. pombe under nitrosative stress. In this study, exposure to an NO donor resulted in S-phase slowdown with associated mitotic block in S. pombe. Deletion of sty1 and atf1 in S. pombe had differential growth sensitivity towards NO donor. Both Sty1 and Atf1 were involved in regulating mitotic slowdown in S. pombe under nitrosative stress. Experimental data obtained in this study reveals a novel role of Atf1 in initiating the replication slowdown in S. pombe under nitrosative stress. Both Sty1 and Atf1 were accumulated in the nucleus in S. pombe under nitrosative stress in a concentration and time dependent manner. Atf1 is also found to be nuclear delocalized under longer nitrosative stress.
