Insights

MicroRNAs (miRs) are small molecules crucial for muscle development and cancer. This review explores their role in normal skeletal muscle and their dysregulation in pediatric rhabdomyosarcoma (RMS).

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • MicroRNAs (miRs) are small non-coding RNAs regulating gene expression.
  • They are vital for tissue development, function, and disease pathogenesis, including cancer.
  • Rhabdomyosarcoma (RMS) is the most common pediatric soft tissue tumor.

Purpose of the Study:

  • To review the current understanding of microRNA roles in normal skeletal muscle development.
  • To summarize the involvement and deregulation of microRNAs in rhabdomyosarcoma pathogenesis.
  • To highlight the potential of miRs as diagnostic, prognostic, and therapeutic tools for RMS.

Main Methods:

  • Literature review of studies on microRNAs in skeletal muscle and rhabdomyosarcoma.
  • Analysis of existing data on microRNA expression patterns in normal and cancerous tissues.
  • Synthesis of information regarding the functional impact of miRs in RMS development.

Main Results:

  • MicroRNAs are key regulators of skeletal muscle differentiation and homeostasis.
  • Specific miRs are frequently deregulated in rhabdomyosarcoma, impacting tumor initiation and progression.
  • Altered miR profiles correlate with distinct RMS subtypes and clinical outcomes.

Conclusions:

  • MicroRNAs play a significant role in both normal muscle development and rhabdomyosarcoma.
  • Deregulation of miRs contributes to the pathogenesis of this pediatric cancer.
  • Targeting miRs presents a promising avenue for novel diagnostic and therapeutic strategies in RMS management.

Formation of Muscle Fibers from Myoblasts01:13

Formation of Muscle Fibers from Myoblasts

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 factors...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Satellite Stem Cells and Muscular Dystrophy

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
