Abstract
The role of the cytostatic factor in the cytotoxic effect of γ-quantum 60Co before and after treatment of cells with a glycolysis inhibitor d-glucosamine was studied on 3 human cell lines. It was shown that treatment of cells with d-glucosamine hydrochloride led to the accumulation of cells in the G1 phase of the cell cycle. The pre-radiation treatment of cells with d-glucosamine leads to a significant (more than 2-fold) increase in the proportion of apoptotically dying tumor cells (lines HeLa G 63, Hep G2), compared with separate exposure, which is not observed for non-tumor cells (ECV 304). d-glucosamine induced selectively directed radiosensitization of tumor cells. A synergistic effect was recorded 48 hours after irradiation. d-glucosamine is believed to inhibit ATP-dependent post-radiation repair processes.
