title: Tiny non-coding RNAs in Parkinson's disease: implications, expectations and hypes.
abstract: Parkinson's disease (PD) is the second most prevalent, progressive and aging related neurodegenerative disorder, characterized by the irreversible and selective degeneration of the nigrostriatal dopaminergic neurons. The early diagnosis, molecular explanation and permanent cure of this devastating and baffling disease have not yet been completely deciphered. Tiny non-coding RNAs, which consist of small or short interfering RNA (siRNA) and micro RNA (miRNA), intervene with and silence the expression of the specific genes through the evolutionary conserved process of RNA interference and act as post-transcriptional regulators. The differential expression patterns of miRNAs operate as key watchdogs and facilitate the identification of the potential therapeutic targets; however, miRNA modifiers aid in designing the strategies to encounter PD. Similarly, siRNA-mediated gene silencing paves the way to understand the function of the specific genes in PD pathogenesis by knocking down their expression. Applications of siRNAs and contributions of the potential miRNAs in investigating the etiology and molecular mechanisms of PD as well as in therapeutic interventions have been discussed in this article. The review also highlights the achievements, expectations and hypes associated with these tiny non-coding RNAs in PD.
