For example, miR-127 has been shown to participate in cancer development [85], miR-145 has been shown to control c-Myc expression through p53 [86], miR-199a regulates MET protooncogene and affects NF-KB expression [54], miR-379 affects brain neuronal development [87], [88], miR-451 affects erythroid differentiation [89], miR-126 affects angiogenic signaling and controls blood vessel development [90], miR-143 regulates ERK5 signaling and targets KRAS gene [91], miR-298 regulates CYPA3 expression [92] and miR-486 regulates kinase activity and tumor progression [93]. The gene discussed is KRAS; the disease is neoplasm.
