Researchers interested in the developing stomach have a new resource, following efforts from scientists at the National Center for Protein Sciences in Beijing to describe the proteomic and transcriptomic changes along the way. The team sampled whole mouse stomachs at fifteen time points, from the earliest embryonic stages at which the stomach can be sampled through several weeks of postnatal development as the organ (and animal) matured. Out of an analysis of 12,108 gene products, they identify 2890 proteins that they consider to be core components of the stomach proteome. Their new atlas also suggests that the mouse stomach develops in three distinct phases, reflected in changes in which proteins and pathways are active. The data are available online in Nature Communications.
