Cardiac REDD1 alters glucose and fatty acid metabolic gene expression via an mTORC1-independent, PPAR alpha-dependent mechanism and drives hypertrophic growth

This study demonstrates that cardiac REDD1 promotes glucose oxidation and hypertrophic growth by suppressing PPARα activity and its downstream targets (such as PDK4) through an mTORC1-independent mechanism.

Species-specific small models for cell type classification approach the performance of large single cell foundation models

The paper introduces CytoType and its simplified variant ESM-CE, species-specific models that leverage pre-trained protein embeddings to achieve cell type classification performance comparable to large foundation models while using orders of magnitude fewer parameters and offering greater interpretability.

Deep phenotyping of ATDC5-derived in vitro cartilage organoids

This study provides a comprehensive molecular characterization of ATDC5-derived cartilage organoids through time-resolved transcriptomic and proteomic analyses, revealing a detailed profile of chondrogenic differentiation and previously unreported extracellular matrix components to enhance the model's utility for studying human genetic skeletal diseases.

Greatwall Kinase regulates Acute Myeloid Leukaemia Cell Division through a Non-Canonical Mechanism

This study reveals that Greatwall kinase drives acute myeloid leukemia cell proliferation through a non-canonical mechanism involving the direct phosphorylation of MARK3 to regulate cytokinesis, rather than the previously established ENSA-PP2A-B55 pathway.

Cell therapy for regeneration of injured donor lungs for transplantation

This study demonstrates that repeated administration of mesenchymal stromal cells (MSCs) during ex vivo lung perfusion and the early post-transplant period, rather than a single dose or the specific cell source, effectively restores function and prevents graft dysfunction in severely injured porcine donor lungs, offering a promising regenerative strategy to expand the organ pool for transplantation.

Physiologically relevant media are associated with overlapping metabolic responses in primary human hepatocytes and Huh7 cells

This study demonstrates that Huh7 cells cultured in physiologically relevant media exhibit metabolic responses and lipid accumulation patterns comparable to primary human hepatocytes, supporting their utility as a scalable in vitro model for studying metabolic dysfunction-associated steatotic liver disease (MASLD).

Cardiomyocyte autophagy promotes a pro-regenerative immune response during cardiac regeneration

This study reveals that cardiomyocyte autophagy, regulated by AP-1 transcription factors, is essential for driving heart regeneration in adult zebrafish by facilitating cardiomyocyte protrusion into injured tissue and modulating macrophage phenotypes from pro-inflammatory to pro-angiogenic and pro-fibrotic states to ensure effective scar resolution.
