摘要

The importance of noncoding genome has become more evident in recent years. Before genome sequencing, the most well studied portion of our genome was protein coding genes. Interestingly, this coding portion accounted only for 1.5% of the genome, the rest being the noncoding sequences. Noncoding RNAs (ncRNAs) are involved in normal cell physiology, stress, and disease states. A class of small ncRNAs and miRNAs has gained much importance because of its involvement in human diseases such as cancer. Involvement of long ncRNAs have also been acknowledged in other human diseases, especially in neurodegenerative diseases. Neurodegenerative diseases are characterized by the presence of abnormally folded proteins that are toxic to the cell. Several studies from model organisms suggest upregulation of pathways that clear this toxic protein may provide protection against neurodegeneration. In this review, I summarize the importance of ncRNAs in protein quality control system of cell that is implicated in this fatal group of neurodegenerative diseases.
