MEIS1: From functional versatility to post-transcriptional/translational regulation

Area of Science:

• Molecular Biology
• Developmental Biology
• Genetics

Background:

• Myeloid ecotropic virus insertion site 1 (MEIS1) is a key transcription factor regulating critical cellular processes.
• Aberrant MEIS1 expression is linked to diseases including cancer, cardiomyopathies, and neurodegeneration.

Purpose of the Study:

• To review the multifaceted roles of MEIS1.
• To emphasize MEIS1's dynamic regulatory networks in physiological and pathological contexts.
• To provide guidance on MEIS1's therapeutic potential.

Main Methods:

• Review of recent advances in MEIS1 regulation.
• Analysis of post-transcriptional and translational mechanisms.
• Exploration of MEIS1's interplay with non-coding RNAs.

Main Results:

• MEIS1 activity is finely tuned by chromatin remodeling, epigenetic modifications, and protein modifications (phosphorylation, ubiquitination).
• MEIS1 interacts with non-coding RNAs, influencing its expression and function.
• Complex regulatory networks govern MEIS1's role in both normal development and disease pathogenesis.

Conclusions:

• MEIS1 is a versatile factor with significant implications in health and disease.
• Understanding MEIS1's regulatory networks is crucial for developing targeted therapies.
• MEIS1 holds promise as a key target for therapeutic innovation across various clinical settings.
