Lysosomes (LY) with antimicrobial (AM) and anticancerous (AC) functions, were altered by some stimuli factor. Unlike LY, peroxisomes (PE) have different cellular functions because they contain oxidative stress related enzymes. In this study, the LY activity under the several stresses have characterized to separate function of LY and PE based on subcellular distribution under several stressful conditions. The AM and AC activity of LY was enhanced as a result of subcellular distribution of LY and PE, and also affected the reduction of melanin pigments intensity. Aminopeptidase Y (APE3) was found as the highest expressed protein in response to oxidative stress by 2-DE. Then, the gene encoding for the APE3 gene was used to construct the recombinant Saccharomyces cerevisiae in order to enhance its activity in LY. As a result, recombinant S. cerevisiae have showed more enhanced AM and AC activity comparing with normal cells. Finally we found that a bacterial growth in blood was inhibited by LY, when we injected LY for therapy of bacterimia in rat. Our results indicated the increase in endogenous levels of LY and their activity following genetic modification may have various applications as AM agent and apoptosis-inducing materials for cancer cells. Therefore, it is very promising to use the organelles from genetic modified cells for improving in vitro and in vivo functions and PE extract as useful agent for skin lightening cosmetics and treatment of hyperpigmentation disorders.
