Abstract

SPECIALTY GRAND CHALLENGE article Front. Genet., 19 January 2011 | https://doi.org/10.3389/fgene.2011.00001

Highlights

  • Most of the newly identified ncRNAs’ functions are unknown, but these transcripts are increasingly recognized as regulators of gene expression

  • The roles of ncRNAs are many and diverse. As they involve in the regulation of cellular differentiation and proliferation, the altered expression of key ncRNAs may lead to certain human diseases (Irminger-Finger et al, 2010)

  • Increasing number of studies indicate that miRNAs are emerging as important modulators in cellular pathways and they play a key role in human diseases (Cho, 2010a)

Summary

Introduction

Most of the newly identified ncRNAs’ functions are unknown, but these transcripts are increasingly recognized as regulators of gene expression. MicroRNA (miRNA) is one important subcategory of ncRNAs. Most of these molecules appear to regulate target gene expression through translation repression or mRNA degradation (Cho, 2007). Increasing number of studies indicate that miRNAs are emerging as important modulators in cellular pathways and they play a key role in human diseases (Cho, 2010a).
