RHOC and cancer: Specifically, the action of miR‐138 in suppressing RhoC has been shown to result in inhibition of cancer cell proliferation, migration, and invasion.48, 49, 74 This makes sense in the context of findings from RhoC null mice, whereby RhoC was demonstrated to play a critical role in inducing cancer metastasis.30 However, the functional interplay between miR‐138 and RhoC in physiological tissue developmental or repair processes is not yet understood.
