AKT1 and mycosis fungoides: Cobomarsen, an inhibitor of miR-155, was created and tested by Seto et al. They also showed that miR-155 regulated several parallel survival pathways (JAK/STAT, MAPK/ERK, and PI3K/AKT), which had previously been linked to MF pathogenesis, and cobomarsen could suppress these processes in vitro [34].
