Studies suppressing dynamin-related protein 1 (Drp1)—a fission protein whose recruitment to mitochondria is facilitated by INF2 (Jin et al., 2017; Korobova et al., 2013)—in breast cancer cells inhibited formation of lamellipodia and suppressed their migration and invasion capabilities (Zhao et al., 2013). The gene discussed is DNM1L; the disease is breast cancer.
