Summary

This summary is machine-generated.

Long non-coding RNA SNHG1 (lncSNHG1) activates quiescent skeletal muscle stem cells (MuSCs). This key factor promotes MuSC proliferation and differentiation via the Wnt/β-catenin pathway, advancing muscle regeneration research.

Area Of Science

  • Muscle stem cell biology
  • Molecular mechanisms of cell activation
  • Non-coding RNA in stem cell regulation

Background

  • Skeletal muscle stem cells (MuSCs) are crucial for muscle tissue maintenance.
  • MuSCs exist in a quiescent state and activate for self-renewal and differentiation.
  • Molecular mechanisms regulating MuSC activation are not fully understood.

Purpose Of The Study

  • To identify key molecular regulators of MuSC activation.
  • To elucidate the role of long non-coding RNAs in MuSC quiescence exit.
  • To investigate the signaling pathways involved in MuSC activation.

Main Methods

  • Transcriptome data analysis of activated MuSCs.
  • Weighted gene co-expression network analysis (WGCNA).
  • Functional studies involving lncSNHG1 overexpression and knockdown.
  • Investigation of the Wnt/β-catenin pathway.

Main Results

  • Identified long non-coding RNA SNHG1 (lncSNHG1) as a key regulator of MuSC activation.
  • lncSNHG1 overexpression enhanced MuSC proliferation and differentiation.
  • lncSNHG1 knockdown inhibited MuSC activation and function.
  • Disruption of the Wnt/β-catenin pathway blocked lncSNHG1-induced quiescence exit.

Conclusions

  • lncSNHG1 is a critical factor promoting the transition of MuSCs from quiescence to activation.
  • lncSNHG1 facilitates MuSC proliferation and differentiation.
  • The Wnt/β-catenin pathway mediates the effects of lncSNHG1 on MuSC activation.

Formation of Muscle Fibers from Myoblasts 01:13

4.7K

De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription...

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Role Of Notch Signalling In Intestinal Stem Cell Renewal 01:12

2.0K

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Canonical Wnt Signaling Pathway 02:54

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Stem Cell Niche 01:26

5.0K

The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
