Signalling pathways in endometrial cancer.

Carcinogenesis is a multistage process, during which the activity of signalling pathways responsible for cell cycle regulation and division is disrupted which leads to inhibition of apoptosis and enhanced proliferation. Improper activation of Wnt/β-catenin and PI3K. Akt pathways play essential role in endometrial cancers (EC), mainly type I.

Replication study for the association of seven genome- GWAS-identified Loci with susceptibility to ovarian cancer in the Polish population.

We investigated the previously-demonstrated association of seven genome-wide association studies (GWAS) single nucleotide polymorphisms (SNPs), including rs2072590 (HOXD-AS1), rs2665390 (TIPARP), rs10088218 and rs10098821 (8q24), rs3814113 (9p22), rs9303542 (SKAP1) and rs2363956 (ANKLE1), as risk factors of epithelial ovarian tumors (EOTs). These SNPs were genotyped in two hundred seventy three patients with EOTs and four hundred sixty four unrelated healthy females from the Polish population. We observed the lowest p values of the trend test for the 9p22 rs3814113 and 8q24 rs10098821 SNPs in patients with all subtypes of ovarian cancer (p(trend) = 0.

Does Metformin affect ER, PR, IGF-1R, β-catenin and PAX-2 expression in women with diabetes mellitus and endometrial cancer?

Objective: Diabetes mellitus, as a risk factor for endometrial cancer (EC), causes an increase in insulin and IGF-1 concentrations in the blood serum. The increase in insulin and IGF-1 are considered mitogenic factors contributory to cancer development. Studies suggest that metformin has preventive activity, decreasing mortality and the risk of neoplasms.

An analysis of polymorphisms within the Wnt signaling pathway in relation to ovarian cancer risk in a Polish population.

Background And Objective: The Wnt/β-catenin signaling pathway has been considered to be a factor in the development and progression of ovarian cancer.

Methods: All patients with ovarian cancer and controls were tested for BRCA1 mutations (5382incC, C61G, 4153delA) with HybProbe assays and for BRCA2 mutation (5946delT) using high-resolution melting curve analysis (HRM). Mutation carriers were excluded from the association analysis.

The influence of metformin in the etiology of selected cancers.

Obesity, hypertension and glucose tolerance disorders have become a growing concern in recent years. It is estimated that over 220 million people suffer from diabetes. It is a condition conducive to cardiovascular diseases, nephropathy, retinopathy and neuropathy but also to the development of many types of cancer.

[Influence of oncological treatment on fertility of women and pregnancy outcome].

Advances in cancer treatment of young patients have resulted in markedly improved survival rates and quality of life. However infertility remains to be one of adverse effects of anticancer therapy. Female patients who receive high-dose abdominal and/or pelvic irradiation or chemotherapy based on alkylating agents are at highest risk of developing ovarian failure.
