ABSTRACT
High-throughput screening (HTS) is a simple, rapid and cost-effective solution to determine active candidates from large library of compounds. HTS is gaining attention from Pharmaceuticals and Biotechnology companies for accelerating their drug discovery programs. Conventional drug discovery program is time consuming and expensive. In contrast drug repurposing approach is cost-effective and increases speed of drug discovery as toxicity profile is already known. The present chapter highlight HTS technology including microplate, microfluidics, lab-on-chip, organ-on-chip for drug repurposing. The current chapter also highlights the application of HTS for bacterial infections and cancer.

In the past few decades, epigenetics has emerged as an important area of study to enable a better understanding of gene expression and its regulation. Due to epigenetics, stable phenotypic changes have been possible without alterations in DNA sequences. Epigenetic changes may occur due to DNA methylation, acetylation, phosphorylation and other such mechanisms which alter the level of gene expression without making any difference to DNA sequences. In this chapter, CRISPR-dCas9 used to bring about epigenome modifications for regulating gene expression towards a therapeutic approaches for treating human diseases have been discussed.
