Book Description
An exciting class of regulatory small noncoding RNAs (ncRNAs) has emerged in recent years that play key role(s) in the etiology/pathogenesis and diagnosis/prognosis of various human diseases including various hematologic and solid cancers, cardiovascular diseases including stroke/atherosclerosis, diabetes, obesity, and metabolic disorders, neuropathies, neurodegeneration including Alzheimer’s Disease, Parkinson’s Disease or Multiple Sclerosis, neurological disorders including epilepsy and muscular dystrophies, liver diseases, pulmonary fibrosis, immune-mediated inflammatory disorders and inflammatory bowel disease, gastritis, autoimmune disorders including arthritis, acromegaly, chronic kidney disease, allergic rhinitis, vitiligo, osteoporosis, obstructive sleep apnea, ocular disease, periodontitis, skeletal muscle atrophy, and parasitic diseases including leishmaniasis, amongst others. These ncRNAs include primarily microRNAs (miRNAs), long noncoding RNAs (lncRNAs), circular RNAs (circRNAs), piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs), small interfering RNAs (siRNAs) or exosomal RNAs (exRNAs), etc. that modulate the expression of target genes thus potentially regulating protein expression in normal versus diseased individuals. This Research Topic recognizes the importance of and seeks to explore, ncRNAs in the diagnosis, etiology, progression, prognosis, and treatment of human disease as well as novel biomarker discovery by multi-omics technologies and other methodologies. Indeed, high-throughput technologies employing deep sequencing, proteogenomic, microarrays, and quantitative real-time PCR have begun to shed new light on the architecture of ncRNA landscapes in various diseases and key signal transduction cascades modulated by these ncRNAs in disease pathology. Epigenetic control of gene expression mediated via miRNAs, for instance, has expanded our understanding of transcriptional and post-transcriptional regulation of gene expression by critical ncRNAs in the cellular milieu. Network biology approaches including the construction of relevant ncRNA networks, ncRNA-mRNA networks, and bioinformatics for mining of ncRNAs, are gaining greater relevance in the search for ‘target hubs’ or novel biomarker(s) of disease. Delineation of ncRNA signatures by transcriptomic profiling or RNA-seq, for example, is an important milestone in furthering our knowledge of the repertoire of specific ncRNAs implicated in various diseases. Further, elucidation of the specific steps of the signaling cascades where ncRNAs exert their regulatory actions will augment our understanding of diseases. This will lead to the development of (i) a novel biomarker, or biomarker signature panel, for disease; (ii) ncRNA-based companion diagnostics for diagnosis of disease; (iii) point-of-care testing devices based on ncRNAs; (iv) newer therapeutic agents that target novel biomarkers with specificity, thereby reducing toxicity; (v) ncRNA-based prophylactic approaches of the future; and, (vi) ncRNA-based prognosis of disease.
