Abstract:
The present study was carried out to demonstrate the epidemiological value of microRNA (miRNA) in colorectal cancer (CRC) by investigating the association between miRNA gene polymorphisms and the susceptibility to CRC. Multiple meta-analyses of reported data were conducted, and odds ratio values and 95% confidence intervals were used to assess these associations. Stata 11.0 software was used to analyze the data and the modified Jadad quality score was employed to evaluate the quality of the retrieved studies. We retrieved 38 studies on the association between miRNA polymorphisms and risk of CRC, however only 15 met the requirements of the inclusion criteria. In conclusion, we identified a variety of miRNAs (miRNA-let-7, miR-34b/c, miR-146a, miR-603 and miR-149) gene polymorphisms that are associated with susceptibility to CRC. However, some miRNAs (miR-192a, miR-608 and miR-27a) are associated with CRC, but not susceptibility to CRC. The results have limitations given the relatively low number of studies available. Therefore, it is necessary to collect data from large sample-size studies to further validate the results.
Insights
Certain microRNA (miRNA) gene variations are linked to colorectal cancer (CRC) susceptibility. Further large-scale studies are needed to confirm these findings on miRNA and CRC risk.
Area of Science:
- Genetics
- Oncology
- Epidemiology
Background:
- Colorectal cancer (CRC) remains a significant global health concern.
- MicroRNAs (miRNAs) play crucial roles in cancer development and progression.
- Understanding the genetic basis of CRC susceptibility is vital for prevention and early detection.
Purpose of the Study:
- To evaluate the epidemiological significance of microRNA gene polymorphisms in relation to colorectal cancer susceptibility.
- To systematically analyze existing data on the association between miRNA gene variations and CRC risk.
Main Methods:
- Conducted multiple meta-analyses of published studies.
- Assessed associations using odds ratios and 95% confidence intervals.
- Utilized Stata 11.0 for data analysis and modified Jadad quality scores to evaluate study quality.
Main Results:
- Identified 15 eligible studies from an initial retrieval of 38.
- Found associations between specific miRNA gene polymorphisms (miRNA-let-7, miR-34b/c, miR-146a, miR-603, miR-149) and CRC susceptibility.
- Observed associations for other miRNAs (miR-192a, miR-608, miR-27a) with CRC, but not specifically with susceptibility.
Conclusions:
- Certain miRNA gene polymorphisms are associated with colorectal cancer susceptibility.
- Some miRNAs are linked to CRC but not directly to susceptibility.
- Limitations include a small number of available studies, necessitating larger sample-size investigations for validation.
