Announcing a new article publication for Zoonoses journal. Schistosomiasis, which is caused by the schistosome worm, poses significant health challenges. Understanding the sexual development and maturation of schistosomes would provide valuable insight for preventing the transmission of schistosomiasis and pathologic damage to the host.
Isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomics was performed to monitor the dynamic proteomic profiles in Schistosoma japonicum during development from pairing-to-maturation. RNA interference (RNAi) experiments were used to elucidate sex-biased gene function.
Of the 2927 identified proteins, 58.6% showed differential expression after comparing sexes and developmental stages. Both male and female worms displayed a similar number of gender-differentially expressed proteins after pairing. However, these proteins exhibited significant gender-specific functions, with reproduction central in females, while males were enriched in metabolic processes. Females exhibited 73% of their time-variant protein expression during 22-26 days post-infection (dpi), while males had 62% during 18-22 dpi, indicating earlier maturation in males. Functional analysis revealed different peptidases expressed during male and female development and maturation. Sex-biased SjU2AF exhaustion led to worm development delay, abnormal reproductive organ development, and death.
Comparative proteomics enhances our understanding of mechanisms underlying schistosome maturation and reveals a new potential target for chemotherapy and vaccines.
