ENO1 and neoplasm: Notably, among the eight cell lines tested, ENO1 was expressed at intermediate or high levels in metastatic cell lines (Hs766T [17], T3M4 [18], CFPAC-1 [19], L3.6pl [20]), and was absent or expressed at lower levels in primary tumor-derived cell lines (BxPC3 [21], PANC-1 [22], PT45 [23], Mia-PaCa2 [24]).
