Nuclear receptors and microRNAs: Who regulates the regulators in neural stem cells?

In this mini-review, we focus on regulatory loops between nuclear receptors and microRNAs, an emerging class of small RNA regulators of gene expression. Evidence supporting interactions between microRNAs and nuclear receptors in the regulation of gene expression networks is discussed in relation to its possible role in neural stem cell self renewal and differentiation. Furthermore, we discuss possible disturbances of the regulatory loops between microRNAs and nuclear receptors in human neurodegenerative disease. Finally, we discuss the possible use of nuclear receptors as pharmacological entry points to regulate neural stem cell self-renewal and differentiation.
