Single nucleotide polymorphisms (SNPs) in cell cycle genes may predict aggressive prostate cancer (PCa). The MDM2 tSNP309g variant showed a significant association with advanced PCa risk in European-Americans.
Area of Science:
- Genetics
- Oncology
- Molecular Biology
Background:
- Single nucleotide polymorphisms (SNPs) are linked to various cancers, including prostate carcinoma (PCa).
- Identifying SNPs associated with aggressive PCa is crucial, given that many patients have low-risk disease.
- This study investigates SNPs in cell cycle genes for their association with advanced PCa.
Purpose of the Study:
- To explore the role of specific single nucleotide polymorphisms (SNPs) in cell cycle genes.
- To determine if these SNPs are associated with advanced prostate carcinoma (PCa).
Main Methods:
- Evaluated nine SNPs in six cell cycle genes within a European-American cohort.
- Included 186 patients with advanced PCa and 222 cancer-free controls.
- Genotypes determined using Pyrosequencing assays.
Main Results:
- One SNP (CDKN1A c10791t) showed statistical significance (P<0.05).
- Two SNPs (CCND1 a870g and MDM2 tSNP309g) approached significance (P<0.1).
- The MDM2 tSNP309g variant was associated with increased risk of advanced PCa (OR 2.26), particularly in androgen-independent disease and younger diagnoses.
Conclusions:
- SNPs in cell cycle genes show promise as markers for aggressive PCa in European-Americans.
- Further research with larger cohorts is necessary to validate these findings.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
