To understand how an internal combustion engine works, we may initially dissect a motorcycle rather than a Mercedes.To understand fundamental mechanisms of cell cycle and gene expression in eukaryotes, there are advantageous to employ yeasts as model organisms to address questions of human interests.Two ongoing projects will be presented as examples.In the first project, using two divergent yeasts: fission yeast and budding yeast, we seek to develop a global picture of the mechanisms for cellular response to phenol derivatives, BPA, BHA, and BHT, which are widely present in daily life as environmental pollutants.We are investigating in an evolutionary context whether the two yeasts handle the environmental challenge in the same way or different ways, that is, using similar pathways and corresponding gene elements or not.In the second project, we explore novel roles of two protein kinases, Dsk1 and Kic1, which are involved in the interplay between cell cycle regulation and multiple steps of eukaryotic gene expression in fission yeast.The two kinases are members of LAMMER-related kinases that are conserved through evolution and play important roles in cell growth, differentiation, hepatitis B virus infection, cancer development and sensitivity to anti-cancer drugs, insulin-regulated glucose metabolism and nutrient homeostasis.
