Researchers confirm molecule's role in kidney formation
Using an innovative screen approach that graduate student Shahram Jevin Poureetezadi designed, the team exposed zebrafish embryos to small molecules, prostaglandin E2, from a chemical library of such molecules known to be active in cell development generally. The researchers wanted to identify small molecules that regulate or modify development. They discovered that activating or interrupting the prostaglandin pathway has a direct impact on the kidney, meaning that it is essential for normal development. The discovery is the culmination of six years of work in the lab, assembling various genes that are important for making kidney cells. Now that the pieces are being connected and the role of prostaglandin is established, Wingert will turn attention to gaining a deeper molecular and mechanistic understanding of how the molecule works in kidney development, especially the gene targets of the signaling. Prostaglandin E2 regulates the formation of blood stem cells and is known to inf...
