This study analyzes the expression and the function of Xenopus msx-1 (Xmsx-1) in embryos, in relation to the ventralizing activity of bone morphogenetic protein-4 (BMP-4). Expression of Xmsx-1 was increased in UV-treated ventralized embryos and decreased in LiCl-treated dorsalized embryos at the neurula stage (stage 14). Whole-mount in situ hybridization analysis showed that Xmsx-1 is expressed...
The establishment of cell and tissue polarity during animal development often requires signaling by Wnts, extracellular signaling polypeptides. Transmembrane receptors of the Frizzled family are implicated in the transduction of Wnt signals in responding cells. Xfz8 is a novel cDNA encoding a Xenopus homologue of mouse Frizzled 8. Xfz8 transcripts are expressed zygotically in the organizer at t...
Hairy cell leukemia (HCL) is a distinct clinicopathologic entity that responds well to purine analogs but is sometimes difficult to differentiate from HCL-like disorders (e.g., splenic marginal zone lymphoma and HCL variant). We recently identified the BRAF-V600E mutation as the disease-defining genetic event in HCL. In this study, we describe a new, simple, and inexpensive test for genetics-ba...
