PERK-dependent regulation of lipogenesis during mouse mammary gland development and adipocyte differentiation
Open accessAbstract
The role of the endoplasmic reticulum stress-regulated kinase, PERK, in mammary gland function was assessed through generation of a targeted deletion in mammary epithelium. Characterization revealed that PERK is required for functional maturation of milk-secreting mammary epithelial cells. PERK-dependent signaling contributes to lipogenic differentiation in mammary epithelium, and perk deletion inhibits the sustained expression of lipogenic enzymes FAS, ACL, and SCD1. As a result, mammary tissue has reduced lipid content and the milk produced has altered lipid composition, resulting in attenuated pup growth. Consistent with PERK-dependent regulation of the lipogenic pathway, loss of PERK inhibits expression of FAS, ACL, and SCD1 in immortalized murine embryonic fibroblasts when cultured under conditions favoring adipocyte differentiation. These findings implicate PERK as a physiologically relevant regulator of the lipogenic pathway.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
