- Emerging roles for organelles in cellular regulation
Organelles not only regulate cell behavior and function but are themselves regulated by internal and external signals.
Research Articles
- A TGFβ–miR-182–BRCA1 axis controls the mammary differentiation hierarchy
TGFβ promotes luminal differentiation of mammary stem cells by suppressing a BRCA1-targeting microRNA.
- Widespread control of calcium signaling by a family of SERCA-inhibiting micropeptides
A family of micropeptides inhibits calcium reuptake by the endoplasmic reticulum in diverse cell types.
- Late-phase synthesis of IκBα insulates the TLR4-activated canonical NF-κB pathway from noncanonical NF-κB signaling in macrophages
Macrophage-specific insulation of canonical NF-κB signaling from the noncanonical pathway prevents excessive inflammation.

About The Cover

Online Cover This week features a Research Article that describes two micropeptides, ALN (another-regulin) and ELN (endoregulin), that inhibit calcium reuptake by the endoplasmic reticulum in diverse cell types. The image shows the distribution of mRNA transcripts encoding ALN (left) and ELN (right) in mouse embryos. [Image: Douglas M. Anderson, Department of Molecular Biology, and John M.
