Less is more: seipin, phospholipids, and embryogenesis

In a recent paper published in Life Metabolism, Zhu et al. revealed that mutations that reduce phosphatidylcholine (PC) synthesis rescue embryonic lethality but exacerbate lipid droplet (LD) abnormalities in C. elegans seipin mutants, demonstrating distinct roles for Seipin in embryogenesis and LD formation.
