Mouse Lefty2 and zebrafish antivin are feedback inhibitors of nodal signaling during vertebrate gastrulation.

abstract：:One of the prominent biological phenomena controlled by Wnt signaling is the expansion of cells with predefined fates. In the November 27, 2002, issue of Cell, Rosenfeld and colleagues describe an example of Wnt-controlled proliferation during genesis of the cardiac outflow tract and the pituitary gland. As a downstre...

abstract：:Histone H2B monoubiquitination (H2Bub1) is centrally involved in gene regulation. The deubiquitination module (DUBm) of the SAGA complex is a major regulator of global H2Bub1 levels, and components of this DUBm are linked to both neurodegenerative diseases and cancer. Unexpectedly, we find that ablation of USP22, the ...
