Thanks to all of the @lamminglab.bsky.social members past and present for another terrific year, all our collaborators and colleagues for their help and friendship, and thanks as well to everyone who has participated in great conversations online and off about healthy aging, diet and mTOR!

We celebrated the graduation of two of our graduate students, Dr. Reji Babygirija and Dr. Mariah Calubag! Reji is now a postdoc with @WiscoSurgMetab while Mariah is looking for a postdoc – snap her up soon!

And we helped push a fascinating story over the finish line, “Dietary lipids are largely deposited in skin and rapidly affect insulating properties” www.nature.com/articles/s41...
Dietary lipids are largely deposited in skin and rapidly affect insulating properties - Nature Communications
The mechanisms underlying the regulation of the skin thermal barrier are poorly understood. Here the authors show that the thermal properties of the skin are reactive to diet and that skin is a target...

Working with Adam Konopka and colleagues we continued to study rapamycin, showing that “Rapamycin Does Not Compromise Exercise-Induced Muscular Adaptations in Female Mice” onlinelibrary.wiley.com/doi/10.1111/...
Rapamycin Does Not Compromise Exercise‐Induced Muscular Adaptations in Female Mice
Rapamycin is largely compatible with the physical and skeletal muscle benefits of progressive weighted wheel running (PoWeR). The detrimental effects of rapamycin on glucose metabolism in the context...

That brings us to our fourth manuscript of the year, “Ketogenesis is Dispensable for the Metabolic Adaptations to Caloric Restriction”, by lab postdoc Dr. Chung-Yang Yeh, onlinelibrary.wiley.com/doi/10.1111/...
Ketogenesis is Dispensable for the Metabolic Adaptations to Caloric Restriction
In this study, we demonstrated that metabolic responses to a daily-fed caloric restriction (CR) protocol remain robust in mice that cannot engage in canonical ketogenesis. This surprising finding is ...

Tissue‐Specific Effects of Dietary Protein on Cellular Senescence Are Mediated by Branched‐Chain Amino Acids
Restriction of dietary BCAAs protects male mice from the metabolic consequences of both normal- and high-protein diets. BCAA restriction also protects from hepatic cellular senescence in vivo and in ...

These effects are not only cell-intrinsic, but are distinct from the effects of rapamycin, suggesting that the effects of AA-depletion on the epigenome are largely mTOR-independent

Isoleucine, the focus of much of our labs research recently, had the strongest effect, w/ "expression of select chromatin modifying and metabolic enzymes that led to a prominent epigenetic state of histone H2A/H4 hypoacetylation and maintained hepatic acetyl-CoA levels"

Surprisingly, this is not the case - ketogenesis is dispensable for the metabolic effects of CR. Indeed, Dr. Yeh discovered that CR mice adapt to the repeated fasting by CR, and over time stop inducing ketogenesis during their inter-meal fast.

CR as typically delivered leads to long periods of fasting between meals - and fasting normally induces ketogenesis. So here, Dr. Yeh tested the hypothesis that ketogenesis contributes to the metabolic benefits of CR.
