Abstract:
:Lipid droplets are fat storage organelles in cells that physically resemble stable oil-water emulsion droplets. In this issue of Developmental Cell, Ben M'barek et al. (2017) show that the resemblance is more than superficial: physical principles governing emulsion stability also control lipid droplet nucleation and growth.

评论,杂志文章,评审abstract::PTEN is one of the most commonly lost tumor suppressors in human cancer and is known to inhibit insulin signaling. Eph receptor tyrosine kinases (RTKs) have also been implicated in cancer formation and progression, and they have diverse functions, including nervous and vascular system development.
