Abstract

Objectives: Osteoporosis is a chronic, generalized bone disease conditioned by many factors among which the genetic background plays the significant role. Bone morphogenetic protein (BMP2), a growth factor belong to superfamily of TNF- proteins, is actively involved in bone tissue metabolism. BMP2 protein shows the osteoinduction potential and regulates growth of cartilage plate, and the same directly influences the process of osteogenesis. The aim: The aim of study was to examine the frequency of genotypes and alleles of 570A>T and 5375G>A of BMP2 gene polymorphisms in population of Polish postmenopausal women, as well as to analyze the relationship between investigated polymorphic variants and bone turnover parameters. Material and methods: Into the study 117 postmenopausal women, Caucasian race (average age 55,1 years) living in Wielkopolska region were classified. The analysis of 570A>T and 5375G>A BMP2 polymorphisms was performed by polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP) while bone mineral density (BMD) was measured by DEXA method. In the research the chosen clinical and bone turnover parameters were analysed. Results: In both 570A>T and 5375G>A BMP2 polymorphisms the similar frequency of genotypes and alleles in investigated groups of postmenopausal women with osteoporosis, osteopenia and in the group with correct T-score were noted. The analysis do not show the relationship of clinical and bone turnover parameters with particular genotypes of BMP2 polymorphisms in women with osteoporosis, osteopenia and in the group with correct T-score. Conclusions: The research did not confirm directly relationship of 570A>T and 5375G>A BMP2 polymorphisms with osteoporosis development in population of Polish postmenopausal women. The investigation also shows lack of correlation of 570A>T and 5375G>A BMP2 polymorphisms polymorphisms with analysed clinical and bone turnover parameters.
