Exogenous MG treatment, a glycolysis by-product and glyoxalase enzyme substrate, exhibited dose and time-dependent toxicity in PCa cells when combined with CA. This combination treatment showed heightened toxicity against PCa cells, attributed to CA's inhibition of Glo-1 expression and the nontoxic doses of exogenous MG.
