The zebrafish pronephric tubule consists of proximal and distal segments and a
collecting duct. The proximal segment is subdivided into the neck, proximal
convoluted tubule (PCT) and proximal straight tubule (PST) segments. The distal
segment consists of the distal-early (DE) and distal-late (DL) segments. How the
proximal and distal segments develop along the anteroposterior axis is poorly
understood. Here we show that knockdown of taz in zebrafish caused shortening and
a significant reduction in the number of principal cells of the PST-DE segment,
and proximalization of the pronephric tubule in 24 hpf embryos. RA treatment
expanded the pronephric proximal domain in normal embryos as in taz morphants, an
effect that was further enhanced upon exposure of taz morphants to RA. The early
pronephric defects in 24 hpf taz morphants led to the failure of anterior
pronephric tubule migration and convolution, and to PCT dilation and cyst
formation in older embryos. In situ hybridization showed weak and transient
expression of taz at the bud stage in the intermediate mesoderm, the source of
pronephric progenitors. The present findings show that Taz is required in the
anteroposterior patterning of the pronephric progenitor domain in the
intermediate mesoderm, acting in part by regulating RA signaling in the
pronephric progenitor field in the intermediate mesoderm.
