Abstract

Myeloid ecotropic virus insertion site 1 (MEIS1) is a transcription factor involved in a myriad of functions such as hematopoiesis, cardiac regeneration, cell cycle progression, and limb and organ development. Its functional versatility extends beyond developmental biology, as aberrant MEIS1 expression has been implicated in various pathological contexts like carcinogenesis, cardiomyopathies, and neurodegenerative disorders. Recent advances in the field have uncovered novel layers of MEIS1 regulation, focusing on post-transcriptional and translational mechanisms, which collectively fine-tune its activity, stability, and subcellular localization. These include chromatin remodeling, epigenetic modifications in the enhancer and promoter regions, and protein modifications like phosphorylation and ubiquitination. The sophisticated regulation of MEIS1 including its interplay with non-coding RNAs (ncRNAs), either being an upstream or downstream of ncRNAs, equally represents an important regulatory mechanism orchestrating MEIS1 expression and function. This review explores the multifaceted roles of MEIS1, emphasizing its dynamic regulatory networks and their implications in physiological and pathological conditions. It also provides forward-thinking guidance on the utilization of MEIS1 in targeted therapies across various clinical settings, highlighting its potential as a key regulatory factor in disease modulation and therapeutic innovation.
