Modeling conserved microRNA expression

translocated chromosome

Insects as models to study the epigenetic basis of disease Excerpt: “…selected insects can be used as models for human diseases with an epigenetic component because the underlying molecular mechanisms (DNA methylation, histone acetylation and the expression of microRNAs) are…
