The study investigates genetic associations between single nucleotide polymorphisms (SNPs) located in CCL2, CCL5, CXCL8, and CXCR2 genes and the onset and progression of endometrial cancer. A case-control design included 282 women, with 132 patients and 150 non-cancerous controls, genotyped by PCR-RFLP assays. Findings show significant links between specific CCL5 and CXCR2 polymorphisms and increased cancer risk. Reported associations remained statistically significant after adjustments for age, diabetes, hypertension, or endometrial thickening above 5 mm.

Taking into account the immunological mechanisms of defense against cancer, an important role is attributed to cytokines. In this case-control study, we aimed to identify the possible associations between selected single nucleotide polymorphisms (SNPs), localized in the CCL2, CCL5, CXCL8, and CXCR2 genes, and the onset and progression of endometrial cancer. We found that CCL5 and CXCR2 polymorphisms were associated with increased cancer risk, while the relationships remained signiﬁcant after adjustments for age, diabetes, hypertension, or endometrial thickening. The selected haplotypes for CCL5 and CCL2 SNPs also correlated with an increased risk of cancer. We concluded that the four polymorphisms studied were signiﬁcantly associated with an increased risk of endometrial cancer. The obtained results may be useful for identifying the signaling pathways involved in observed genetic changes, which is important for the tumorigenesis of endometrial cancer. Abstract: Signiﬁcant relationships with endometrial cancer were demonstrated, both for CCL2, CCL5, and CXCL8 chemokines and for the chemokine receptor CXCR2 . The reported case-control study of genetic associations was designed to establish the role of selected single nucleotide polymorphisms (SNPs) of the CCL2, CCL5, CXCL8, and CXCR2 genes in the onset and progression of endometrial cancer. This study was conducted on 282 women, including 132 (46.8%) patients with endometrial cancer and 150 (53.2%) non-cancerous controls. The genotypes for CCL2 rs4586, CCL5 rs2107538 andrs2280789, CXCL8 rs222753

FAQs

What is the main research question of the study?

The study examines whether specific SNPs in chemokine-related genes (CCL2, CCL5, CXCL8, CXCR2) are associated with the onset and progression of endometrial cancer.

How was the study designed and how many participants were included?

A case-control study was conducted with 282 women, including 132 endometrial cancer patients and 150 non-cancer controls.

Which genetic variants were associated with increased endometrial cancer risk?

CCL5 and CXCR2 polymorphisms showed significant associations with increased cancer risk, and certain haplotypes for CCL5 and CCL2 were also linked to higher risk.
