Defective protein synthesis leads to diseases. If protein synthesis can be controlled, disease causing molecules can be tailored in some way. This is the perception behind RNA interference. RNA interference (RNAi) therapeutics is branch of medicine which deals with the treatment of diseases while controlling the gene expression at RNA level. The motive of this chapter is to discover the state-of-the-art of RNAi therapeutics, to explore various techniques used by RNAi therapeutics to fight from diseases, and discuss the future prospects of it.

Common diseases are complex, multifactorial disorders whose pathogenesis is influenced by the interplay of genetic predisposition and environmental factors. Genome-wide association studies have interrogated genetic polymorphisms across genomes of individuals to test associations between genotype and susceptibility to specific disorders, providing insights into the genetic architecture of several complex disorders. However, genetic variants associated with the susceptibility to common diseases are often located in noncoding regions of the genome, such as tissue-specific enhancers or long noncoding RNAs, suggesting that regulatory elements might play a relevant role in human diseases. Enhancers are cis-regulatory genomic sequences that act in concert with promoters to regulate gene expression in a precise spatiotemporal manner. They can be located at a considerable distance from their cognate target promoters, increasing the difficulty of their identification. Genomes are organized in domains of chromatin folding, namely topologically associating domains (TADs). Identification of enhancer–promoter interactions within TADs has revealed principles of cell-type specificity across several organisms and tissues. The vast majority of mammalian genomes are pervasively transcribed, accounting for a previously unappreciated complexity of the noncoding RNA fraction. Particularly, long noncoding RNAs have emerged as key players for the establishment of chromatin architecture and regulation of gene expression. In this perspective, we describe the new advances in the fields of transcriptomics and genome organization, focusing on the role of noncoding genomic variants in the predisposition of common diseases. Finally, we propose a new framework for the identification of the next generation of pharmacological targets for common human diseases.

For a long time scientists have tried to describe disorders are due to genetic as well as environmental factors. In the past few years, revolution in technology that has made it possible to decipher the human genome. Epigenetics explains the capability gene expression regulation without modifying the genetic sequence. Epigenetic mechanisms are rooted changes in molecules, or nuclear characteristics that can alter gene expression without altering the sequences of DNA, i.e. DNA methylation, histone modification, and non-coding RNAs. Learning of the fundamental epigenetic modification allowing gene expression as well as cellular phenotype are advanced that novel insights into the epigenetic control of cardiovascular disease, hepatic disease, as well as chronic kidney disease are now emerging. From a half of century ago, in human disease the role of epigenetics has been considered. This subject has attracted many interests in the past decade, especially in complicated diseases like cardiovascular disease, hepatic disease as well as chronic kidney disease. This review first illustrates the history and classification of epigenetic modifications and the factors (i.e. genetic, environment, dietary, thought process and lifestyle) affecting to the epigenetics mechanisms. Likewise, the epigenetics role in human diseases is think out by targeting on some diseases and at the end, we have given the future perspective of this field. This review article provides concepts with some examples to describe a broad view of distinct aspects of epigenetics in biology and human diseases. Keywords: - Epigenetics, DNA methylation, Histone modifications, microRNAs and Gene expression and Disease.

miRNAs are fascinating molecular players for gene regulation as individual miRNA can control multiple targets and a single target can be regulated by multiple miRNAs. Loss of miRNA regulated gene expression is often reported to be implicated in various human diseases like diabetes and cancer. Recently, geneticists across the world started reporting single nucleotide polymorphism (SNPs) in seed sequences of miRNAs. Similarly, SNPs are also reported in various target sequences of these miRNAs. Both the scenarios lead to dysregulated gene expression which may result in the progression of diseases. In the present paper, we explore SNPs in various miRNAs and their target sequences reported in various human cancers as well as diabetes. Similarly, we also present evidence of these mutations in various other human diseases.
