Wnt and frizzled expression during regeneration of internal organs in the holothurian Eupentacta fraudatrix.
Abstract
Several genes of the Wnt and Frizzled families in the holothurian Eupentacta fraudatrix are characterized, and the complete coding sequences of wntA, wnt4, wnt6, wnt16, frizzled1/2/7, frizzled4, and frizzled5/8 are obtained. The dynamics of expression of these genes during regeneration of internal organs after evisceration are studied. Evisceration and the associated damages supposedly induce the expression of wnt16 on third day after evisceration. Genes wntA, wnt4, wnt6, and frizzled1/2/7 up-regulate during the period of active morphogenesis (5-7 days after evisceration) and might participate in regulation of tissue and organ formation. The signaling induced via Frizzled5/8 is could be necessary for formation of the anterior (ectodermal) part of the digestive system and development of the calcareous ring on 10th day after evisceration. Our data suggest that the Wnt signaling pathway plays a significant role in the regulation of regeneration of internal organs in holothurians.
