Expression data from Saccharomyces cerevisiae temperature-sensitive strains specific for SCF core components (Skp1, Cullin (Cdc53), E2 enzyme (Cdc34)) and the F-box protein Cdc4.


ABSTRACT: The target of rapamycin (TOR) plays a central role in eukaryotic cell growth control. With prevalent hyper-activation of the mTOR pathway in human cancers, novel strategies to enhance TOR pathway inhibition are highly desirable. We used a yeast-based high-throughput chemical genetic screen to identify small-molecule enhancers of rapamycin (SMERs) and used whole genome expression analysis to identify their mechanisms of action. We incubated various temperature-sensitive yeast strains at either the permissive (room temperature) or non-permissive (35°C) temperature for 1 hour prior to RNA extraction and hybridization on Affymetrix microarrays. Comparison of expression profiles enabled identification of gene-signatures specific to inhibition of each gene product.
