abstract = {INTRODUCTION: Methylation of genomic DNA is one of the major mechanisms that deactivates genes and regulates their tissue-specific transcription levels. Its patterns are based on clonal inheritance that occurs in the early stages of embryogenesis. All changes in the DNA methylation levels occurring especially in the promoter region of the genes, which involve hypo- as well as hyper-methylation, lead to cell differentiation and growth disorders. Therefore it can become an impulse that initiates different pathological processes including carcinogenesis. MATERIAL AND METHODS: The purpose of this review was to present the recent knowledge concerning methylation of genomic DNA based on recent references and authors' experience. RESULTS AND CONCLUSION: Genome stability disorders could be caused either by mutations, which damage the structure of the genes and have not been formerly removed, or as the consequence of an epigenetic mechanism. Methylation plays a decisive role in the activity of many genes and could be a natural weapon of an organism against the expression of foreign genetic material that degrades the original genome structure.},

abstract = {Malignant transformation results from accumulation of genetic and epigenetic events. Functional studies of cancer will be crucial to our understanding of its complexity and polymorphism. There is no doubt that emerging genomic and proteomic technologies will facilitate such investigations. Microarray technology is a new and efficient approach to extract data of biomedical relevance for a wide range of applications. In cancer research, it will provide high-throughput and valuable insights into differences in an individual's tumor as compared with constitutional DNA, mRNA expression, and protein expression and activity. Across individuals, comparisons could provide tissue-specific disease signatures that provide diagnosis based on hundreds of informative genes. The resulting product should be a wealth of tumor-associated and tumor-specific biomarkers, which may help in cancer etiology, diagnosis, and therapy and ultimately lead to "molecular nosology" of cancers. This review highlights the recent developments in microarray technologies in cancer research, focuses on the results obtained so far, and describes the eventual use of microarray technology for clinical applications.},

abstract = {DNA methylation level from woman ovarian malignant tissues was investigated by 32P postlabeling of the single nucleotides, separation on TLC with followed autoradiography and Cerenkov counting. Slight differences in DNA methylation extent were found in malignant ovarian tumors as compared to normal myometrium and benign uterine tumor [myomas]. Lowest level of m5dC in relation to C and also in relation to total DNA was found in carcinoma embryonal tissue whereas maximal DNA methylation level was obtained in folliculoma tissue. This preliminary report needs further investigation of particularly genes methylation.},
