Association between lncrna PCGEM1 polymorphisms and prostate cancer risk

Area of Science:

• Genetics
• Oncology
• Molecular Biology

Background:

• Prostate cancer (PCa) is a significant health concern.
• The long noncoding RNA PCGEM1 plays a role in PCa.
• The association between PCGEM1 genetic variations and PCa risk was previously unstudied.

Purpose of the Study:

• To investigate the association between PCGEM1 gene polymorphisms and prostate cancer risk in Chinese men.
• To analyze the impact of specific tagging single-nucleotide polymorphisms (tSNPs) on PCa susceptibility.

Main Methods:

• Genotyping of two PCGEM1 tSNPs (rs6434568 and rs16834898) in a Chinese cohort.
• Statistical analysis using odds ratios (ORs) and 95% confidence intervals (CIs) to assess risk.
• Evaluation of combined effects of risk alleles and their association with clinical parameters.

Main Results:

• The rs6434568 AC/AA genotypes and rs16834898 AC/CC genotypes were associated with a significantly decreased risk of PCa.
• The combined genotypes carrying four risk alleles (rs6434568 C and rs16834898 A) showed an increased risk of PCa.
• This increased risk was more pronounced in younger men (≤70 years), those with higher Gleason scores (≥7), and elevated PSA levels (≥20).

Conclusions:

• PCGEM1 gene polymorphisms may influence prostate cancer risk in Chinese men.
• Specific PCGEM1 variants are associated with altered PCa risk.
• Further functional studies are needed to elucidate the underlying mechanisms.
