Desert Hedgehog/Patched 1 signaling specifies fetal Leydig cell fate in testis organogenesis.

abstract：:In Xenopus embryos, a dorsal-ventral patterning gradient is generated by diffusing Chordin/bone morphogenetic protein (BMP) complexes cleaved by BMP1/Tolloid metalloproteinases in the ventral side. We developed a new BMP1/Tolloid assay using a fluorogenic Chordin peptide substrate and identified an unexpected negative...

abstract：:The connection between RNA and protein export from the nucleus was examined in the budding yeast Saccharomyces cerevisiae. NPL3 encodes an RNA-binding protein that shuttles in and out of the nucleus. Export of poly(A)+ RNA has been shown previously to be blocked in np13-1 mutants. To understand the role of Np13p in RN...
