Identification and expression analysis of thyroid-stimulating hormone β subunit, and effects of T3 on gonadal differentiation-related gene expression in rice field eel, Monopterus albus

These results indicate that Thyroid-stimulating hormone may be involved in sex differentiation, and THs may play roles in the regulation of male development and sex reversal in rice field eel

Scholarcy highlights

  • Rice field eel tshβ was cloned and characterized, which was highly conserved in teleost
  • Monopterus albus, a protogynous hermaphroditic fish, which undergoes sex reversal from a functional female to a male, is an ideal model to investigate the regulation of sex differentiation
  • The tissue distribution indicated that tshβ showed high expression in the pituitary, moderate expression in the brain region, gonad, intestine and liver, and low expression in other peripheral tissues
  • The expression of tshβ had no significant difference in the pituitary
  • These results indicate that Thyroid-stimulating hormone may be involved in sex differentiation, and THs may play roles in the regulation of male development and sex reversal in rice field eel
