Abstract:
Endometrial cancer (EC) remains one of the most common cancers of the female reproductive system. Epidemiological and clinical data implicate insulin resistance (IR) and its accompanying hyperinsulinemia as key factors in the development of EC. MicroRNAs (miRNAs) are short molecules of non-coding endogenous RNA that function as post-transcriptional regulators. Accumulating evidence has shown that the miRNA expression pattern is also likely to be associated with EC risk factors. The aim of this work was the verification of the relationships between IR, EC, and miRNA, and, as based on the literature data, elucidation of miRNA's potential utility for EC prevention in IR patients. The pathways affected in IR relate to the insulin receptors, insulin-like growth factors and their receptors, insulin-like growth factor binding proteins, sex hormone-binding globulin, and estrogens. Herein, we present and discuss arguments for miRNAs as a plausible molecular link between IR and EC development. Specifically, our careful literature search indicated that dysregulation of at least 13 miRNAs has been ascribed to both conditions. We conclude that there is a reasonable possibility for miRNAs to become a predictive factor of future EC in IR patients.
Insights
Insulin resistance (IR) is linked to endometrial cancer (EC). MicroRNAs (miRNAs) may serve as a molecular bridge, with 13 dysregulated miRNAs associated with both conditions, suggesting potential for EC prediction in IR patients.
Area of Science:
- Oncology
- Endocrinology
- Molecular Biology
Background:
- Endometrial cancer (EC) is a common gynecological malignancy.
- Insulin resistance (IR) and hyperinsulinemia are recognized risk factors for EC development.
- MicroRNAs (miRNAs) are key post-transcriptional regulators with altered expression patterns observed in various diseases, including EC.
Purpose of the Study:
- To investigate the intricate relationship between IR, EC, and miRNA expression.
- To explore the potential of miRNAs as biomarkers for EC risk in patients with IR.
- To elucidate the molecular mechanisms linking IR and EC through miRNA dysregulation.
Main Methods:
- Comprehensive literature review and data synthesis.
- Analysis of pathways implicated in IR, including insulin signaling and sex hormone regulation.
- Identification of miRNAs with dysregulated expression in both IR and EC.
Main Results:
- At least 13 miRNAs exhibit dysregulated expression in both IR and EC.
- MiRNAs are proposed as a plausible molecular link connecting IR and EC pathogenesis.
- Specific pathways involving insulin receptors, IGFs, SHBG, and estrogens are affected in IR.
Conclusions:
- Dysregulated miRNAs represent a potential molecular bridge between IR and EC.
- MiRNAs show promise as predictive biomarkers for identifying individuals at higher risk of developing EC, particularly those with IR.
- Further research into miRNA's role could lead to novel strategies for EC prevention in at-risk populations.
