The Roles of Non-Coding RNAs in the Pathogenesis of Uterine Fibroids

Area of Science:

• Gynecologic Oncology
• Molecular Biology
• Genetics

Background:

• Uterine fibroids are common benign tumors affecting approximately 70% of women, with Black women experiencing higher incidence.
• Tumor growth is influenced by estrogen, progesterone, and genetic mutations (e.g., MED12, HMGA2, FH).
• The precise pathogenesis of uterine fibroids remains largely unknown, limiting effective therapeutic strategies.

Purpose of the Study:

• To explore the role of non-coding RNAs (ncRNAs) in the pathogenesis of uterine fibroids.
• To investigate how factors like race, MED12 mutations, and ovarian steroids affect ncRNA expression in fibroids.
• To assess the potential of ncRNAs as therapeutic targets for uterine fibroids.

Main Methods:

• Analysis of non-coding RNA expression profiles in uterine fibroids.
• Investigating the influence of race/ethnicity, MED12 mutations, and hormonal status on ncRNA expression.
• Review of current literature on ncRNA involvement in fibroid development and progression.

Main Results:

• Non-coding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, are increasingly implicated in regulating genes involved in fibroid development.
• Aberrant ncRNA expression is linked to key fibroid processes such as extracellular matrix production, cell proliferation, apoptosis, and inflammation.
• Expression of ncRNAs is influenced by race/ethnicity, MED12 mutations, and ovarian steroids, highlighting their complex role in fibroid pathogenesis.

Conclusions:

• Dysregulated ncRNAs play a significant role in the molecular mechanisms underlying uterine fibroid development.
• ncRNAs represent promising biomarkers and therapeutic targets for uterine fibroids.
• Targeting ncRNAs could lead to novel, individualized, non-hormonal treatments for uterine fibroids.
