Non-mammalian model organisms in epigenetic research : an overview

Boekbijdrage - Hoofdstuk

Recent advances in sequencing technology and genome editing tools had an indisputably enormous impact on our understanding of complex biological pathways and their genetic and epigenetic regulation. Unlike genetics, a study of phenotype development as a result of genotypic diversity, epigenetics studies the emergence of (possibly heritable) phenotypic assortment from one DNA sequence. Epigenetic modifications (i.e., DNA methylation, histone tail modifications, noncoding RNA interference, and many others) are diverse and can bring an additional layer of complexity to phenotype development and it's inheritance. Still, today, detailed mechanisms behind the development of epigenetic marks, their interaction, and their role in transgenerational inheritance of phenotypes are not fully understood. Therefore, chromatin biology and epigenetic research have a rich history of chasing discoveries in a variety of model organisms, including yeast, worms, flies, fish, and plants. Use of these models has opened numerous new avenues for investigation in the field. In the coming future, model organisms will continue to serve as an inseparable part of studies related to interpreting complex genomic and epigenomic data, gene–protein functional relationship, various diseases pathways, aging, and many others. Use of the model organism will provide insights not only into novel genetic players but also the profound impact of epigenetics on phenotype development. Here, we present a brief overview of the most commonly used nonmammalian model organism (i.e., fruit fly, nematode worm, zebrafish, and yeast) as potential experimental systems for epigenetic studies.
