Discovery of stabilized functional mutants of human aquaporin 1 by Soh, Miao Yi

“…A cell-based freeze-thaw functionality assay that was developed by the lab was conducted on yeast Saccharomyces cerevisiae cells transformed with the plasmids to identify the functional mutants, i.e., mutants that express the mutated AQP1 protein that would allow them to exhibit a protective effect in response to rapid freezing. ~ 5% of mutants from a total of 2816 screened from thirty-three 96-well plates were identified after a series of initial and verification screens. …”

Legionella pneumophila filamentous morphological form and the generation of novel spherical form upon interaction with protozoan hosts by Chan, Sock Hoai

“…Our investigation showed that filamentation cannot be neatly pegged to a single dominant factor but is promoted under a concerted influence of environmental conditions leaning towards (i) higher than ambient temperatures, at 37-42°C, (ii) static fluid movement, and (iii) with at least a minimal organic content of 5% buffered yeast extract, or equivalent. In the course of investigating interaction of the filamentous form with protozoan hosts, a spherical form was discovered. …”

Finding transcription factor binding motifs for coregulated genes by combining sequence overrepresentation with cross-species conservation by Jia, Hui., Li, Jinming.

“…Compared with the prevailing motif finding software, our method has some advantages in finding transcriptional factor binding motifs for potential coregulated genes if the gene upstream sequences of multiple closely related species are available. Although we used yeast genomes to assess our method in this study, it might also be applied to other organisms if suitable related species are available and the upstream sequences of coregulated genes can be obtained for the multiple closely related species.…”
