An Overview of Aptamer: The Prominent Applications and Different Computational Tools for its Design.

BACKGROUND: Aptamers are short single-stranded oligonucleotides; due to their 3D structure, they can specifically bind to various targets. They can target several molecules ranging from metal ions, organic components to proteins, and large cells.
METHODS: According to the high affinity of aptamers, they can be used for diagnosis, therapeutic, vaccine development, and gene silencing applications. The conventional method for aptamer selection is known as the Systematic Evolution of Ligands by Exponential (SELEX). However, despite the efficiency of SELEX as a screening procedure, it is beneficial to develop more rational procedures for aptamer selection. RESULTS & DISCUSSION: Herein, in silico approaches can play an effective role given their potential in representing an efficient, cost-effective, parallelizable, and rapid strategy. In recent years, several attempts have been applied to develop algorithms and software for the rational selection of aptamers. However, there is still a need for more efforts to achieve the most efficient techniques in this area.
CONCLUSION: In this review, we aim to overview different computational approaches that are used for aptamer selection. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.
