mi RNA210, one of the important hypoxamirs, is reported to be a regulator of many cellularmechanisms including cell division, differentiation, apoptosis, cell cycle regulation, mitochondrial function, metabolism etc. Sincehypoxia is the microenvironment that prevailed in preeclampsia it is worth full to see the expression pattern of mi RNA 210 as anattempt to unearth the preeclampsia pathogenesis. This evidence concerns the gene MITF and preeclampsia.
