“…Inside the cytoplasm, a new reaction, initiated by an RNAse III endonuclease called Dicer and by the RNA binding protein (TRBP), takes place, which leads to the formation of the final microRNA species [17,20,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88]. The last step involves coupling the RNA-induced silencing complex (RISC) [18,78,79,80,81,82,83,84,85,86,87,88,89,90,91]. The final molecular species is then transported outside the cell through different mechanisms and in various forms, such as ribonucleoprotein complexes, microvesicles, exosomes, and high-density lipoproteins (Figure 1) [14].…”
