UCHL1 and neoplasm: Focusing on Ubiquitin Carboxyl-Terminal Hydrolase L1 (UCHL1), a deubiquitinating enzyme that has a putative oncogenic role in various cancer types [13,14,15,16,17,18], we sought to elucidate the molecular mechanism by which UCHL1 promotes tumor progression in USC, and evaluated the effect of targeting UCHL1 on tumor cell proliferation in vivo.
