For single cell foundation model fans, Raul Rabadan & colleagues just published GET in @nature.com, which trained on chromatin accessibility data to predict transcription factor interactions/motifs, cis-regulatory elements, & gene expression from 213 human cell types www.nature.com/articles/s41...

First 2025 metabolism publication in @nature.com is from Michael Karin's group, finding that metabolic hepatosteatosis promotes senescence of hepatocytes, but is bypassed through transcriptional inactivation of FBP1, a novel gatekeeper against hepatocellular carcinoma www.nature.com/articles/d41...

Paradoxical link between senescent cell state and liver cancer resolved
DNA damage caused by a high-fat diet can increase the risk of tumour formation in the liver.

Two studies published recently in @nature.com proposed cryoEM structures of the lipoprotein apoB. Some of the biggest protein-lipid complexes ever visualized and some cool insights into lipoprotien bio.

Sleeping is one of my fav activities. Very excited that we got to share this study by @mcalpinelab.bsky.social showing that cardiac inflammation after a heart attack dictates sleep patterns and promotes healing/recovery. www.nature.com/articles/s41...

A great study by @lydialynch.bsky.social 's group showing that IL-17 producing immune cells in adipose dictate the circadian rhythm of that tissue and orchestrate de novo lipogenesis and systemic metabolism www.nature.com/articles/s41...

Rhythmic IL-17 production by γδ T cells maintains adipose de novo lipogenesis - Nature
Innate IL-17-producing T cells—in particular, adipose γδ17 T cells—are enriched in molecular-clock genes, and the circadian expression of IL-17A and RORγt by these cells has a role in maintaining loca...

First post! Didn't see this study on @bsky.app. From @zgerharthines.bsky.social group identifying neuronal NK2R as a regulator of feeding/hunger & energy expenditure, and demonstrating the efficacy of a small molecule agonist in non-human primates for weight loss. www.nature.com/articles/s41...

🧬 New in @Nature: Our team found that fat cells keep a “memory” of their previous obese state even after weight loss, helping explain why maintaining weight loss is so challenging. Excited to share this work!! www.nature.com/articles/s41...
