Glucocorticoid signalling exerts distinct lineage-permissive and dose-dependent disruptive actions during human osteoblast differentiation

At physiological levels glucocorticoid (GC) signalling within the osteoblast lineage has been proposed to be required for skeletal homeostasis, whereas supraphysiological activation supresses bone formation and causes bone loss. While these observations suggest that GC exert dose- and context-dependent effects, the mol...

Mitochondrial carrier SLC25A34 links clock, diet, and temperature control of adipocyte lipid cycling.

Adipocyte lipid metabolism is coordinated by circadian rhythms, diet, and environmental temperature, but how these diverse signals are molecularly integrated remains unknown. We showed that these cues converge on the orphan mitochondrial transporter SLC25A34 to orchestrate lipid cycling. During the sleep phase, the adi...

Mitochondrial membrane lipid cardiolipin controls fiber-type adaptations in aging muscle via estrogen-related receptor γ

Aging paradoxically leads to both a decline in skeletal muscle mitochondrial function and a shift in muscle composition that favors fibers rich in mitochondria. Yet the biological rationale and mechanism underlying this phenomenon remain largely unknown. Here we show that synthesis of the mitochondrial membrane lipid,...
