Gene Activity Changes in Male Black Tiger Shrimp After Eating Polychaetes to Boost Testis Development

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated

Abstract

Transcriptomic profiles of male black tiger shrimp fed polychaetes showed significantly higher expression levels of certain genes compared to those fed commercial pellets.

  • Six out of eleven differentially expressed genes were validated to have higher expression in polychaete-fed shrimp.
  • Differentially expressed genes were linked to DNA replication and microtubule formation pathways.
  • Nutrient uptake and nucleotide production genes were elevated only in the testes, while those related to protein refolding and cell death were increased in the vas deferens.
  • These changes may enhance sperm production by promoting spermatogonia growth in the testes and regulating mature sperm in the vas deferens.
