In lung cancer, miR-200c inhibits cancer cell invasion through the ubiquitin specific peptidase 25 (USP25) protein (Li J. et al., 2014), which is a peptidase primarily associated with protein ubiquitination and may intervene with TGFβ signaling and EMT (Soond and Chantry, 2011). The gene discussed is USP25; the disease is cancer.
