Roles of the canonical myomiRs miR-1, -133 and -206 in cell development and disease

Area of Science:

• Molecular Biology
• Genetics
• Cell Biology

Background:

• MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression and cellular pathways.
• Aberrant miRNA expression is linked to disease development and progression.
• MyomiRs (miR-1, -133, -206) are crucial for muscle development and health.

Purpose of the Study:

• To review the multifaceted roles of myomiRs beyond muscle tissues.
• To examine myomiR involvement in cell development, tissue regeneration, and inflammation.
• To investigate the association of myomiR deregulation with cancer development and progression.

Main Methods:

• Literature review of studies on myomiR function and expression.
• Analysis of myomiR roles in non-muscle tissues, including neural, adipose, and immune cells.
• Examination of myomiR involvement in cancer, considering both tumor suppressor and oncogenic functions.

Main Results:

• MyomiRs exhibit regulatory roles in diverse non-muscle tissues, impacting development and function.
• MyomiR deregulation is implicated in various cancers, often acting as tumor suppressors.
• Evidence suggests both tumor suppressor and oncogenic roles for myomiRs depending on the cellular context.

Conclusions:

• MyomiRs are key regulators at the intersection of tissue development, regeneration, inflammation, and cancer.
• Understanding myomiR functions in different cellular environments is crucial for therapeutic strategies.
• Further research is needed to fully elucidate the complex roles of myomiRs in health and disease.
