Transcriptomic responses of juvenile Pacific whiteleg shrimp, Litopenaeus vannamei, to hypoxia and hypercapnic hypoxia

ABSTRACT: Here we used microarrays to characterize changes in global gene expression in the hepatopancreas of Pacific white shrimp, Litopenaeus vannamei, exposed to short term (4 h) hypoxia (H) or hypercapnic hypoxia (HH) or long term (24 h) H or HH, compared to animals in air-saturated water (normoxia). The transcriptomes of crustaceans exposed to low O2 and high CO2 contained both shared and treatment-specific signature genes (q M-bM-^IM-$ 0.01, FC M-bM-^IM-% 1.5), with shifts characteristic of metabolic depression rather than anaerobic metabolism. Down-regulated signature genes dominated the transcript profile in three of the four treatments (H 4 h, H 24 h, 4 h HH); many of these genes were involved in amino acid or RNA metabolism or in translation, including several tRNA synthetases.
