Background:
Aberrant alternative splicing included alterations in components of the mRNA splicing machinery often occurred in colon cancer. However, the role of SF3A1, one key component of the mRNA splicing machinery, on colorectal cancer (CRC) risk was still not elucidated.
Method And Findings:
We performed a hospital-based case-control study containing 801 CRC patients and 817 cancer-free controls to examine the association between SF3A1 polymorphisms and CRC risk in a Chinese population. Four candidate SNPs (rs10376, rs5753073, rs2839998 and rs2074733) were selected based on bioinformatics analysis and previous findings. The results showed no significant associations between these SNPs and CRC risk (P > 0.05). Besides, the stratified analysis based on the smoking and alcohol use status obtained no statistically significant results.
Conclusion:
Our study was the first one to investigate the association between SF3A1 polymorphisms and CRC risk. The results suggested these four SNPs in SF3A1 were not associated with CRC risk in a Chinese population, however, further more studies are needed to confirm our findings.
Insights
This study found no association between SF3A1 gene polymorphisms and colorectal cancer (CRC) risk in a Chinese population. Further research is needed to confirm these findings on CRC development.
Area of Science:
- Genetics
- Oncology
- Molecular Biology
Background:
- Aberrant alternative splicing is common in colon cancer.
- SF3A1, a key splicing factor, has an unclear role in colorectal cancer (CRC) risk.
- Understanding SF3A1's role is crucial for CRC research.
Purpose of the Study:
- To investigate the association between SF3A1 gene polymorphisms and CRC risk.
- To analyze specific single nucleotide polymorphisms (SNPs) in the SF3A1 gene.
- To evaluate the influence of SF3A1 variations on CRC susceptibility in a Chinese population.
Main Methods:
- A hospital-based case-control study was conducted.
- 801 CRC patients and 817 cancer-free controls were included.
- Four candidate SF3A1 SNPs (rs10376, rs5753073, rs2839998, rs2074733) were analyzed.
Main Results:
- No significant association was found between the studied SF3A1 SNPs and CRC risk (P > 0.05).
- Stratified analyses based on smoking and alcohol consumption also yielded no significant results.
- The investigated genetic variations in SF3A1 do not appear to influence CRC risk in this population.
Conclusions:
- This is the first study to examine SF3A1 polymorphisms in relation to CRC risk.
- The findings suggest that the four selected SF3A1 SNPs are not associated with CRC risk in the studied Chinese population.
- Further studies are warranted to validate these results and explore other potential genetic factors in CRC development.
