PQM-1 controls hypoxic survival via regulation of lipid metabolism.

Worms were exposed to 5 mM CoCl2 at the early day 1 of adulthood stage for 6 hr and 20 hr. Untreated worms were used as controls. Worms were collected, RNA isolated and hybridized on 4x44K C. elegans arrays (Agilent) at 60C overnight, as previously described 1). Three biological replicates were used. Significant differentially-expressed gene sets were identified using one or two-class SAM 2). 1) Shaw, W. M., Luo, S., Landis, J., Ashraf, J. & Murphy, C. T.
