Effect of 2-DG and 5-FU combination in vitro. (a) Caspase 3/7 activation, normalized on ACTB protein expression measured by western blot (data not shown), and (b) Annexin V analysis of HepG2 cells treated with 2-DG (10 and 20 mM), 5-FU (2.5 μM) or in combination in Dulbecco’s modified Eagle’s medium (DMEM) low glucose for 24 h. Only bright annexin was measured as high apoptosis rate was detectable in treated cells.
