MicroRNAs (miRNAs) are noncoding RNAs that are highly relevant as disease biomarkers. Aim: This study aimed to accurately identification of potential miRNAs for gastric cancer (GC) diagnosis at the early stages of the disease. It is estimated that miRNAs constitute nearly 1% of all predicted genes in nematodes, flies. miRNAs are associated with various pathological conditions due to the disruption of miRNA biogenesis or its complex that results in dysregulation of miRNAs, leading to inappropriate expression and consequently function []. 1. Dysregulation of miRNA expression has been implicated in numerous diseases 7, including cancer 8,9. Figure 1. miRNAs in TNBC Tumorigenesis, Promotion, Progression and Stemness. They were found to be associated with leaf morphogenesis, flowering time, vegetative phase change, and response to. The biogenesis of microRNAs (miRNAs) in plants is a unique and evolutionary divergent pathway that differs from its counterpart in metazoans 1,2. However, this strength of miRNAs is also a weakness because. An interaction graph of the 55 conserved miRNAs from Ae. Plant miRNA targets frequently fit into diverse. MicroRNAs (miRNAs) are a class of short, single-stranded, noncoding RNAs, with a length of about 18–22 nucleotides. MicroRNAs (miRNA) are a noncoding RNA species that play important roles in the regulation of gene expression. MiRNAs, approximately 18–26 nucleotides long, are expressed in plants, fungi, animals, and unicellular organisms and their synthesis is a finely regulated multi-step process .
