the research illustrates how the control of adipocyte lipolysis by circulating ketone bodies is important for normal metabolic homeostasis. Thanks to the many contributors in the two Cambridges!

Genetic impairment of ketone body signalling is a prevalent contributor to human metabolic dysfunction Emerging evidence that circulating levels of key metabolic intermediates are sensed by a range of G-Protein Coupled receptors (GPCRs) is providing critical new insights into the control of systemic me...

Cardiac adaptation to endurance exercise training requires suppression of GDF15 via PGC-1α - Nature Cardiovascular Research Khetarpal et al. show that the metabolic regulator PGC-1α is essential in heart muscle cells for exercise-driven cardiac growth, and that suppression of the stress-induced myokine GDF15 is required to enable cardiomyocyte adaptations to training.

Interesting. But studies of GDF15 on cells used GDF15 made in mammalian cells which is always contaminated by TGFB family members (see PMID: 29161287) some of which are active at fmolar concs. Yeast or bacterially derived is fine. Qkine is good source

Patrick Vallance hits pause on Research Excellence Framework Science minister announces review of controversial changes to research environment assessment

Fantastic news. Processes designed to measure Research excellence should focus on whether research done at our universities is reproducible, represents a significant advance in understanding, and/or is actually or potentially useful. The rest is just prattle.

Glucose-dependent insulinotropic polypeptide receptor signaling in oligodendrocytes increases the weight-loss action of GLP-1R agonism Hansford et al. show that GIPR, a target of new weight-loss drugs, is found in brain cells called oligodendrocytes. GIPR helps these drugs access the brain and boosts weight loss. Without GIPR in thes...

OMG. This looks terrifying.

Mice lacking this amino acid lost 30% of their body weight But eliminating cysteine, which is found in high-protein foods, from human diets would be challenging.

Mice lacking this amino acid lost 30% body weight www.nature.com/articles/d41... Am I missing something? Mice engineered to have a specific and severe defect in amino acid metabolism get sick and lose weight. Might the rush to find new weight loss targets be impairing our critical faculties ?

I did start my talk by showing the photo and saying (with a wry smile, of course) how delighted I was to be in Uppsala….

Had a great time at Lund university attending their Spring Meeting. Amused to see this poster outside the lecture theatre. Those old English universities: it’s hard to tell them apart 😊

Indeed. And so ironic that while the new administration says it is very keen to understand the effects of food on health, their actions are resulting in the closure of one the US’s most effective labs in that area @kevinh-phd.bsky.social

Carole Hooven: Why I Left Harvard After I stated banal facts about human biology, I found myself caught in a DEI web, without the support to do the job I loved. The only way out was to leave it.

www.thefp.com/p/carole-hoo.... While I applaud Harvard for standing up to the Trump government, this article is mandatory reading for anyone who doesn’t understand how it got to this point.

UK’s supreme court rules that legal definition of woman is based on biological sex. This is a hugely important decision. Unanimous .I hope it will open up rational debate in other countries.

Thanks so much Brent. I hope I made it clear in my talk that the discovery of the role of GDF15 in pregnancy sickness was very much an international collaborative effort

I really enjoyed recording one of these with you several years ago. Wishing you well with whatever your next venture will be.
