1/Patient-derived xenografts (PDXs) are used in preclinical testing of cancer therapies, including metabolic therapies. We determined which metabolic properties are retained, and which are lost, when melanomas from patients are implanted and passaged as PDXs in mice.

Conservation and divergence of metabolic phenotypes between patient tumours and matched xenografts - Nature Metabolism
Rao and Cai et al. perform a detailed metabolic comparison between primary tumours from patients and their matching xenografts, which identify conserved as well as divergent metabolic patterns.

What if you could chart cells' regulatory programs at unprecedented resolution?
In my work with Jorge Martin-Rufino from the @bloodgenes.bsky.social lab, we dissect the genome’s control circuits and find where key genetic variation hides

Transcription factor networks disproportionately enrich for heritability of blood cell phenotypes
Most phenotype-associated genetic variants map to noncoding regulatory regions of the human genome, but their mechanisms remain elusive in most cases. We developed a highly efficient strategy, Perturb...

Stem cell-like states confer poor outcomes in blood cancer—but what mechanisms drive this and how can they be therapeutically targeted? In our new preprint, we show how a single TF represses one enhancer to maintain a subset of high-risk leukemias: 🧵👇

Congrats to Salma Merchant for Cell Stem Cell paper: the effects of fatty acid oxidation in hematopoietic stem cells are context dependent. FAO is not necessary in young HSCs, but becomes necessary during aging, and is deleterious when upregulated by a high fat diet.

Different effects of fatty acid oxidation on hematopoietic stem cells based on age and diet
Morrison and colleagues show long-chain fatty acid oxidation has context-dependent effects on hematopoietic stem cells (HSCs). It is dispensable for HSC function in young mice. It becomes necessary for normal HSC function and hematopoiesis in older mice. A high-fat diet increases fatty acid oxidation, and this impairs HSC function.
