MetabolomicsSerine synthesis pathway enzyme PHGDH is critical for muscle cell biomass, anabolic metabolism and mTORC1 signaling

Cells use glycolytic intermediates for anabolism e.g., via the serine synthesis and pentose phosphate pathways. However, we still understand poorly how these metabolic pathways contribute to skeletal muscle cell biomass generation. The first aim of this study was therefore to identify enzymes tha...

MetabolomicsGenomic and lipidomic actions of nandrolone on detached rotator cuff muscle in sheep
Reversal of fatty infiltration of pennate rotator cuff muscle after tendon release is hitherto impossible. The administration of nandrolone starting at the time of tendon release prevents the increase in fat content, but does not revert established fatty infiltration. We hypothesised that tendon rel...

MetabolomicsPhotosynthetic bioenergetic-redox restoration rejuvenates the aged muscle regenerative niche

Aging impairs muscle regeneration, but the key constraint remains unclear. Aged injured muscle fails to restore mitochondrial respiration, membrane potential, ATP/NADPH balance and redox control, forming a bioenergetic-redox bottleneck. To target this, we engineered CM-NTU-Ce, a C2C12 membrane-co...

MetabolomicsRegulatory T cells promote endurance exercise adaptation by shielding muscle mitochondria from damage

Exercise enhances physical performance and reduces the risk of many disorders such as cardiovascular disease, type 2 diabetes, dementia and cancer. Exercise characteristically incites an inflammatory response, notably in skeletal muscles. While some effector mechanisms have been identified, regul...

GenomicsThe Mediator MED23 plays opposing roles in directing smooth muscle cell and adipocyte differentiation
The Mediator complex functions as a control center orchestrating diverse signalings, gene activities, and biological processes. However, how Mediator subunits determine distinct cell fates remains to be fully elucidated. Here, we show that Mediator MED23 controls the cell fate preference that direct...

MetabolomicsMetabolomics Identifies Metabolic Markers of Maturation in Human Pluripotent Stem Cell-Derived Cardiomyocytes
Cardiovascular disease is a leading cause of death worldwide. Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) hold immense clinical potential and recent studies have enabled generation of virtually pure hPSC-CMs with high efficiency in chemically defined and xeno-free conditions. Despi...

TranscriptomicsmicroRNA-222 regulates muscle alternative splicing through Rbm24 during differentiation of skeletal muscle cells
A number of microRNAs have been shown to regulate skeletal muscle development and differentiation. MicroRNA-222 is downregulated during myogenic differentiation and its overexpression leads to alteration of muscle differentiation process and specialized structures. By using RNA induced silencing com...

TranscriptomicsERK5 Regulates Muscle Cell Fusion through Klf Transcription Factors
In skeletal muscle differentiation, muscle-specific genes are regulated by two groups of transcription factors, the MyoD and MEF2 families, which work together to drive the differentiation process. Here we show that ERK5 regulates muscle cell fusion through Klf transcription factors. The inhibition ...

ProteomicsIdentification of proteolytic events during C2C12 myoblast differentiation
Identification of product of proteolysis during C2C12 myoblast differentiation using subtiligase N-terminomics. Different cell populations collected during a time-course of differentiation (4 days) were used for N-terminal labeling in a forward degradomics approach (n=2). Day0 population= Myoblasts,...
