Noncoding RNA and Cardiomyocyte Proliferation

Abstract EN

It is acknowledged that postnatal mammalian cardiomyocytes (CMs) turn over with a very limited efficacy in both physiological and pathological conditions.

Recent studies showed that those newly formed CMs are derived from preexisting CMs.

Thus, stimulating CM proliferation becomes a promising strategy for inducing cardiac regeneration.

Noncoding RNAs were found differently expressed in CMs with different proliferation potential.

Moreover, manipulation of noncoding RNAs, in particular microRNAs, was proved to promote or suppress CM proliferation, indicating that noncoding RNAs are involved in the underlying mechanism of CM proliferation.

This review mainly summarizes the roles of noncoding RNAs, as a class of influential factors, in the regulation of CM proliferation.
