Lymph node environment drives FSP1 targetability in metastasizing melanoma - Nature Targeting FSP1 in lymph nodes has considerable potential for blocking melanoma progression.

Melanoma cells that spread to lymph nodes depend on FSP1 to survive, revealing a new metabolic vulnerability. New study in Nature by @mariopalma.bsky.social @ubellackerlab.bsky.social and colleagues shows that blocking FSP1 triggers ferroptosis and suppresses tumor growth in lymph node metastases.

The diabetes gene Tcf7l2 organizes gene expression in the liver and regulates amino acid metabolism Though Tcf7l2 harbors the strongest genetic association with diabetes identified thus far, how it promotes metabolic disease remains unclear. Our aim …

New Molecular Metabolism study from the Biddinger Lab finds diabetes gene TCF7L2 is crucial for hepatic zonation and glutamine metabolism. Liver-specific Tcf7l2 knockout mice exhibit metabolic reprogramming, and decreased glutamine in humans with the rs7903146 variant. #BiddingerLab

I Was Just About To When My Grant Was Cut. We ask researchers to send us their stories of what they were working on when their research grant was cut. Today, we share the stories of Tashara and Brendan.

Just two of thousands of such stories. substack.com/home/post/p-...

Using a phospho-mutant TSC2-5A mouse, the work reveals tissue-specific roles for this pathway in organ growth, including reduced brain and muscle size. Congratulations to all contributing researchers on this important publication! #Metabolism #ManningLab

AKT-mediated phosphorylation of TSC2 controls stimulus- and tissue-specific mTORC1 signaling and organ growth Cormerais et al. describe the TSC2-5A mouse model lacking the five phosphorylation sites on TSC2 through which AKT activates mTORC1. The TSC2-5A mice are developmentally normal but show reduced body- ...

New study in @cp-devcell.bsky.social from the @bdmanning.bsky.social Lab.

Brendan Manning: Unraveling the cell’s inner workings For Brendan Manning, PhD, today’s advances in basic science are the stepping stones to the next breakthrough in treating tuberous sclerosis complex (TSC). Manning has spent the last 25 years researchi...

For 25 years, Dr. Manning & his lab have advanced TSC research, uncovering how the mTOR pathway shapes cell growth—and unlocking insights across cancer, diabetes & more. Research that until recently was supported by taxpayers through the NIH. #TSC #science #ResearchMatters

Newly discovered mechanism of mitochondrial dysfunction in obesity may drive insulin resistance and type 2 diabetes | Harvard T.H. Chan School of Public Health A newly discovered mechanism that leads to liver dysfunction may be a key factor in type 2 diabetes and other metabolic disorders in individuals with obesity, according to a new study led by Harvard C...

From @hsph.harvard.edu Hotamışlıgil Lab, @renata-goncalves.bsky.social identifies an important mechanism that leads to liver dysfunction in obesity—defective coenzyme Q metabolism. This finding paves the way for more targeted diabetes & metabolic disease treatments. Read more:

🗓️ Join us Friday, Apr 25 for a #seminar with Brendan Manning — Professor and Chair of Molecular Metabolism at Harvard T.H. Chan School of Public Health.
He'll explore the TSC-mTOR pathway in growth and metabolism. Don’t miss it! @bdmanning.bsky.social @met-hsph.bsky.social @mario-pende.bsky.social

A reminder that for next month’s BCDI in place of our regular discussion, we encourage you to attend the Cutter Distinguished Lecture @met-hsph.bsky.social by the great Scott Dixon!

See you there: Monday May 12, 2025, Kresge Building at HSPH, G1 auditorium, 12:00-1:00pm

This study has advanced the frontier of in vivo flux quantification, offering important tools and resources for metabolic research. Incredible work by all researchers involved! #Metabolism #ObesityResearch

An organism-level quantitative flux model of energy metabolism in mice Mammalian tissues feed on nutrients in the blood circulation. At the organism level, mammalian energy metabolism is comprised of the oxidation, storag…

Exciting findings from Bo Yuan, PhD of the @tonyhui.bsky.social Lab: a whole-body quantitative flux model of energy metabolism was built, revealing surprising features of energy metabolism in both normal physiology and obesity. Great collaboration with the Hotamışlıgil Lab!

Great work, led by Dr. Hotamisligil, Postdoctoral Fellow Dr. Baazim and the research team!
