Neddylation Is a Novel Therapeutic Target for Lupus by Regulating Double Negative T Cell Homeostasis

[Signal Transduction And Targeted Therapy] The authors reported that neddylation inactivation with MLN4924, a specific inhibitor of NEDD8-activating enzyme E1, or genetic abrogation of Ube2m in T cells decreased double-negative T cell accumulation and attenuated murine lupus development.

Depletion of SAM Leading to Loss of Heterochromatin Drives Muscle Stem Cell Aging

[Nature Metabolism] The authors showed that heterochromatin markers, including histone H3K9 di/tri-methylation and HP1, decreased with age in muscle stem cells as a consequence of the depletion of the methyl donor S-adenosylmethionine.

Machine Learning Inference of Continuous Single-Cell State Transitions during Myoblast Differentiation and Fusion

[Molecular Systems Biology] Investigators combined live-cell imaging and machine learning to monitor ERK1/2-inhibited primary murine skeletal muscle precursor cells, that transitioned rapidly and robustly from proliferating myoblasts to post-mitotic myocytes and then fuse, forming multinucleated myotubes.

Serping1 Associated with α-Synuclein Increase in Colonic Smooth Muscles of MPTP-Induced Parkinson’s Disease Mice

[Scientific Reports] The morphological changes and association between serping1 and α-syn were investigated in the colon of the 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine-induced chronic Parkinson’s disease model.

DNMT3A Clonal Hematopoiesis-Driver Mutations Induce Cardiac Fibrosis by Paracrine Activation of Fibroblasts

[Nature Communications] Researchers used combined transcriptomic data derived from peripheral blood mononuclear cells of heart failure patients, both with and without CHIP, and cardiac tissue.

MITOL Deficiency Triggers Hematopoietic Stem Cell Apoptosis via ER Stress Response

[EMBO Journal] The authors investigated the functional involvement of MITOL in HSC maintenance by generating MX1-cre inducible Mitol knockout mice.
