Bastos et al. Multiple technological platforms have been developed for miRNA isolation, miRNA quantitation, miRNA profiling, miRNA target detection, and modulating miRNA levels in vitro and in vivo. (C) The pre-miRNA forms a complex with exportin-5. Gene Expression Profiling. microRNA and small RNA profiling can reveal fascinating insights into a multitude of diseases. ) need to undergo a series of processes as depicted in the flow diagram ( Figure 1 ). Small noncoding RNAs act in gene silencing and post-transcriptional regulation of gene expression. This species is capable of diving > 900 m deep and remaining underwater for more than 60 min. have identified miR-31 as an oncomiR in lung cancer (43).
