Plasminogen activator inhibitor-1 (PAI-1) gene 4G/5G promoter polymorphism is not associated with breast cancer.
Acta Biochim Pol. 2000; 47(1):191-9.AB

Abstract

The antigen content of plasminogen activator inhibitor-1 (PAI-1) in primary breast cancer tissue extracts may be of strong prognostic value: high levels of PAI-1 in tumors predict poor prognosis for patients. The gene encoding PAI-1 is highly polymorphic and an insertion (5G)/deletion (4G) polymorphism in the PAI-1 gene promoter (the 4G/5G polymorphism), may have functional significance in PAI-1 expression. In the present work the distribution of genotypes and frequency of alleles of the 4G/5G polymorphism in subjects with breast cancer were investigated. Tumor tissues were obtained from 100 postmenopausal women with node-negative and node-positive ductal breast carcinoma with uniform tumor size. Blood samples from age matched healthy women served as control. The 4G/5G polymorphism was determined by PCR amplification using the allele specific primers. The distribution of the genotypes of the 4G/5G polymorphism in both control and patients did not differ significantly (P > 0.05) from those predicted by the Hardy-Weinberg distribution. There were no differences in the genotype distributions and allele frequencies between node-positive and node-negative patients. The 4G/5G polymorphism may not be linked with elevated level of PAI-1 observed in breast cancer and therefore may not be associated with appearance and/or progression of breast cancer.
