Research interestMy first project in the Hohmann lab was to investigate the role and regulation of the yeast aquaporin Aqy2. Water is the major component of all living organisms and hence the transport of water into and out of cells is a fundamental process of life. Aquaporins exist in all organisms from bacteria to mammals and are thought to play important roles in the control of water homeostasis and turgor. The yeast Saccharomyces cerevisiae possesses two aquaporins, Aqy1 and Aqy2. We reported that Aqy2 is involved in controlling cell surface properties and that its expression is controlled by osmoregulatory and morphogenic signalling pathways. Our observations relate to the proposed role of mammalian aquaporins in tumour cell migration and invasion. (Furukawa et al., 2009, Mol Microbiol) See also a short review article (in Japanese).
In certain yeast strains such as Sigma1278b, diploid cells develop pseudohyphae under nitrogen starvation, while haploid cells produce invasive filaments that penetrate the agar in rich medium. During the study of yeast aquaporin, we found that these morphological developments are strongly inhibited under hyper-osmotic condition through the high-osmolarity glycerol (HOG) response MAPK pathway. Fungal Hog1 orthologues are thought to be central negative regulators of many aspects of morphological developments and virulence, and studies on the underlying mechanisms are relevant for the identification of novel targets for antifungal therapy. We have recently developed an efficient method for construction of diploid strains using a galactose-inducible mating-type switch gene (PGAL1-HO) and a counter selection marker gene (PSTE18-URA3), and applied our method to the study of yeast morphological developments.

I was involved in the CELLCOMPUT project (EC-funded FP6 project), which aims at generating cell communication systems that form building blocks for biological computation devices. This collaboration paper has been published in Nature (Regot et al., 2011). See also our press release. During this project, I got interested in synthetic biology. See our review article (Furukawa and Hohmann, 2013, Mol Microbiol) and short articles, Synthetic biology using yeast and Synthetic biology leading to health care (in Japanese). My current project is to elucidate properties of the yeast HOG pathway using a synthetic biological approach (Babazadeh et al., 2014, Sci Rep). In addition, I am trying to control yeast cell fate by combinatorial integration of various genetic toolkits including heterologous kinases (Furukawa et al., 2012, FEBS Lett), constitutively active components and chemical-inducible promoters.
