The latest progress on miR-374 and its functional implications in physiological and pathological processes.

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• Non-coding RNAs (ncRNAs) are crucial regulators of gene expression.
• MicroRNAs (miRNAs) are a class of ncRNAs with diverse regulatory functions.
• The miR-374 family, located at the X-chromosome inactivation center, has emerged as significant in various biological processes.

Purpose of the Study:

• To review the multifaceted roles of miR-374 family members in physiological and pathological conditions.

• Analysis of miRNA biogenesis and regulatory mechanisms.
• Synthesis of data on miR-374's involvement in various diseases.

Main Results:

• MiR-374 family members regulate gene expression through direct mRNA targeting and indirect interactions with other ncRNAs.
• These miRNAs are implicated in reproductive disorders, cell growth, kidney calcium handling, cancers, and epilepsy.
• Evidence suggests miR-374 family members play critical roles in both normal physiology and disease pathogenesis.

Conclusions:

• The miR-374 family is a vital regulatory unit with broad implications in human health and disease.
