Osteoporosis is an age related disease characterised by a progressive decrease of bone mineral density and loss of bone quality. Twin studies show that genetic component contributes up to 85% of the BMD variability of population. Surprisingly little variability of BMD can be explained by genetic polymorphisms (~2.9%). This highlights the complex genetic architecture and suggests that many other molecular processes and genes have to be involved. Our previous research showed tha...

miRNAs are epigenetic regulators of gene expression, increasingly recognised as prominent regulators of bone metabolism. Following our in vitro studies of miRNAs profiles in osteoblasts we extended the research to human bone samples. Our aim was to find and functionally validate miRNAs differentially expressed in osteoporotic and osteoarthrotic bone with potential for targeting genes relevant in bone metabolism.Trabecular bone tissue samples wer...
