ABSTRACT Background Liver‐related sarcopenia is a devastating systemic complication of chronic liver disease (CLD) driven by mechanisms extending beyond nutritional deficiency. However, the role of liver‐derived humoral factors remains unclear. We utilised a unique cohort of human skeletal muscle biopsies to test the hypothesis that serum conjugated ...

Macrophage-released ADAMTS1 promotes muscle stem cell activation. [PDF]
Coordinated activation of muscle stem cells (known as satellite cells) is critical for postnatal muscle growth and regeneration. The muscle stem cell niche is central for regulating the activation state of satellite cells, but the specific extracellular ...

Abstract Skeletal muscles are exquisitely designed to produce force that facilitate movement. Circadian “molecular clocks” residing in muscle play a role in regulating force production with muscle stem cell (satellite cells, SC) molecular clocks modulating isometric and eccentric force according to time‐of‐day.

MLL1 is required for PAX7 expression and satellite cell self-renewal in mice
PAX7 transcription factor specifies the myogenic identity of muscle stem cells and acts as a nodal factor by stimulating proliferation while inhibiting differentiation.

Regulation of Pax7 protein levels by caspase-3 and proteasome activity in differentiating myoblasts
The transcription factor Pax7 negatively regulates the activity of the muscle regulatory transcription factor MyoD, preventing muscle precursor cells from undergoing terminal differentiation.

Essential for muscle fiber formation and hypertrophy, muscle stem cells, also called satellite cells, reside beneath the basal lamina of the muscle fiber.

The Satellite Cell Niche Regulates the Balance between Myoblast Differentiation and Self-Renewal via p53 [PDF]
Satellite cells are adult muscle stem cells residing in a specialized niche that regulates their homeostasis. How niche-generated signals integrate to regulate gene expression in satellite cell-derived myoblasts is poorly understood.

Segregation of striated and smooth muscle lineages by a Notch-dependent regulatory network [PDF]
Background: Lineage segregation from multipotent epithelia is a central theme in development and in adult stem cell plasticity. Previously, we demonstrated that striated and smooth muscle cells share a common progenitor within their epithelium of origin,

Comparative expression analysis of Pax3 and Pax7 during mouse myogenesis
Pax3 and Pax7 are closely related transcription factors involved in the commitment of myogenic precursors in the developing trunk. However, it is not yet clear whether these genes are required for myogenic cell specification in the head and for post-somitic myogensis per se.
