Transcriptional profiling of Caenorhabditis elegans and Caenorhabditis briggsae before and after heat shock


ABSTRACT: Transcriptional profiling of heat-shocked worms was compared to non-heat-shocked worms to determine genes that are induced upon heat shock in each species; heat-shock-induced genes in each species were compared Overall design: 3 biological replicates were performed for both control (NHS) and heat-shocked (HS) worms of each species giving a total of 12 samples

Heat Shock Factor 1 (HSF-1) is a key regulator of the heat shock response (HSR). Upon heat shock, HSF-1 binds well-conserved motifs, called Heat Shock Elements (HSEs), and drives expression of genes important for cellular protection during this stress. Remarkably, we found that substantial numbers of HSEs in multiple <i>Caenorhabditis</i> species reside within Helitrons, a type of DNA transposon. Consistent with Helitron-embedded HSEs being functional, upon heat shock they display increased HSF-  ...[more]
