MRNA-seq of L1 larvae recovering from arrest


ABSTRACT: We used RNA-seq to sequence the transcriptome of worms arrested in the first larval stage after hatching without food and starved for 12 hours, then a timecourse of animals recovering from arrest after feeding. We collected samples after 12 hours of starvation and 1, 3 and 6 hours after feeding. Four time points (12 hr starvation and 1, 3, and 6 hr of recovery) with three biological replicates at times 0 and 6 and two biological replicates at times 1 and 3.

Nutrient availability profoundly influences gene expression. Many animal genes encode multiple transcript isoforms, yet the effect of nutrient availability on transcript isoform expression has not been studied in genome-wide fashion. When Caenorhabditis elegans larvae hatch without food, they arrest development in the first larval stage (L1 arrest). Starved larvae can survive L1 arrest for weeks, but growth and post-embryonic development are rapidly initiated in response to feeding. We used RNA-  ...[more]
