“…The caspase-3, -8, -9 activities were determined by fluorometric assay kit according to the manufacturer's protocol as we described previously [20,31]. Briefly, lysates of HepG2 cells were prepared after treating with 2-DG (0, 2, 5, 10 mM), UP12 (0, 0.5, 1.5, 5 mM) and 2-DG (mM) + UP12 (mM) (0, 2 + 0.5, 5 + 1.5, 10 + 5) for 24 h. Lysates were incubated at 37 8C for 4 h. Samples were measured on an ELISA reader at 405 nm.…”
