Impacts of Interleukin-10 Promoter Genotypes on Prostate Cancer.

Area of Science:

• Genetics
• Immunology
• Oncology

Background:

• Prostate cancer (PCa) is a multifactorial disease influenced by genetic, environmental, and immunological factors.
• Genetic polymorphisms in the interleukin-10 (IL-10) gene have been linked to PCa susceptibility and progression.

Purpose of the Study:

• To investigate the association between three IL-10 promoter single nucleotide polymorphisms (SNPs) and PCa risk in Taiwan.
• To evaluate the impact of IL-10 SNPs on PCa development and progression.

Main Methods:

• Genotyping of three IL-10 promoter SNPs (A-1082G, T-819C, A-592C) using PCR-RFLP.
• Case-control study with 218 PCa patients and 436 non-PCa controls.

Main Results:

• No significant association was found between the three IL-10 SNPs and overall PCa risk.
• The GG genotype at rs1800896, combined with smoking, significantly increased PCa risk (OR = 3.90).
• The rs1800896 AG and GG genotypes were associated with late-stage PCa (OR = 1.90 and 6.42, respectively).

Conclusions:

• The IL-10 promoter SNP A-1082G (rs1800896) may be a risk factor for PCa in smokers and patients with late-stage disease.
• Further validation in larger, diverse populations is recommended.
