Lipid droplets
OK, they are cute, but why should a developmental biologist care about them? Onset of calcification early in ontogeny coupled with gradual, progressive morphological development permits the recognition of growth sequences for over a hundred trilobite species. Striking variation in the number of trunk segments at maturity across ontogeny and phylogeny, coupled with the curious pattern of segment...
متن کاملCytoplasmic lipid droplets are sites of convergence of proteasomal and autophagic degradation of apolipoprotein B.
Lipid esters stored in cytoplasmic lipid droplets (CLDs) of hepatocytes are used to synthesize very low-density lipoproteins (VLDLs), into which apolipoprotein B (ApoB) is integrated cotranslationally. In the present study, by using Huh7 cells, derived from human hepatoma and competent for VLDL secretion, we found that ApoB is highly concentrated around CLDs to make "ApoB-crescents." ApoB-cresc...
متن کاملCharacterization of the Proteome of Cytoplasmic Lipid Droplets in Mouse Enterocytes after a Dietary Fat Challenge
Dietary fat absorption by the small intestine is a multistep process that regulates the uptake and delivery of essential nutrients and energy. One step of this process is the temporary storage of dietary fat in cytoplasmic lipid droplets (CLDs). The storage and mobilization of dietary fat is thought to be regulated by proteins that associate with the CLD; however, mechanistic details of this pr...

متن کاملLipid droplets go nuclear
Lipid droplets (LDs) are sometimes found in the nucleus of some cells. In this issue, Ohsaki et al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201507122) show that the nuclear membrane, promyelocytic leukemia bodies, and the protein PML-II play a role in nuclear LD formation, suggesting functional relationships between these structures.
