Opis:
Cytogenetics is complementary to genetic and molecular analysis of genome structure and function. From the beginning it has been mainly used for identification of chromosomes and karyotype construction. Most significant for the progress in cytogenetics was development of chromosome banding techniques and in situ hybridization, especially fluorescent in situ hybridization (FISH) and its different modifications which have become the most important techniques in molecular cytogenetics. FISH allows physical gene mapping and localization of different non-coding DNA sequences on chromosomes and interphase nuclei. Repetitive DNA sequences can generate unique FISH-signal patterns on individual chromosomes valuable for karyotyping and phylogenetic analysis. These studies have important implications for basic research and practical applications. The understanding of the structure, function, organization and evolution of genomes enabled many new cytogenetic applications to both medicine and agriculture, particularly in diagnosis and plant breeding.

Opis:
Cholesteatoma is described as cystic lesion consisting of keratinizing squamous cell epithelium, filed with keratin debris, surrounded by inflammatory fibrous tissue, gradually expanding in the middle ear and causing destruction of neighboring bones. This paper presents brief review of existing hypotheses explaining its etiology in the light of the researches using high throughput, “omics”, technologies of molecular biology. Classic theories of pathogenesis of acquired cholesteatoma as: immigration, squamous metaplasia, basal cell hyperplasia or invagination theory have not been able to explain fully all pathological processes observed in cholesteatoma tissue. This also concerns the newer concepts that cholesteatoma is a result of mucosal traction generated by interaction of migrating opposing surfaces, a natural attempt by the body to cure the underlying inflammation in the cavity or chronic wound healing process triggered by micro defects in the basement membrane of the epithelium in the retraction pocket. Introduction of high-throughput, “omics”, technologies of molecular biology to the studies under cholesteatoma pathogenesis allowed identification of cholesteatoma-related gene expression signatures using full-genome microarrays as well as proteomic analysis of cholesteatoma. Those studies confirmed known pathological processes observed in cholesteatoma tissue such as: high proliferative activity, decreased signal transduction, active immunological response, alterations in the extracellular matrix, increased expression of proinflammatory cytokines, neovascularization and may others. This technique allows precise and complete insight into molecular mechanisms in those processes. However, it is still unknown what is the cause that trigger epithelial hyperplasia, inhibited migration and inflammatory response in the preexisting retraction pocket.

Opis:
Deoxyribonucleic acid (DNA) was identified 140 years ago by a Swiss physician Friedrich Miescher. His discovery was fundamental for the development of biochemistry, genetics and molecular biology. Contemporary biology, biotechnology and medicine largely depends on our ability to analyze, synthesize and manipulate DNA. We present highlights of the history of DNA research from the very beginning to the sequencing of human genome.
