Abstract

Abstract:

Objective To explore the function of sox19b on the eye development in zebrafish by knockdown of sox19b. Methods To inhibit the expression of sox19b by microinjection of sox19b morpholinos（MO）and then observe the effect of the development of the eyes in zebrafish by RT-PCR and the whole-mount in situhybridization. Results The development of the eyes was abnormal after knockdown of sox19b, mainly showed small eyes or eye deficiency and the abnormal retina and lens(n =57/93). The expression of some important genes during the development of the eyes, such as rx3, pax2a and vsx2, was decreased apparently in the sox 19b morphant. Conclusion The transcription factor, sox19b is critical for the development of the eyes via the regulation of the important eye-field transcription factors,EFTEs in early zebrafish embryos.
