AIM: To study the effects of combinational treatment of hyperbaric oxygen (HBO) and nanotemozolomide in glioma.
MATERIALS & METHODS: Temozolomide (TMZ)-loaded porous silicon nanoparticles (TMZ/PSi NPs) were prepared. In vitro and in vivo evaluations were performed.
RESULTS: The cell uptake of TMZ/PSi NPs could be tracked by autofluorescence of porous silicon. The concentration of oxygen in tumor was improved and the antitumor rate was increased to 84.2% in the TMZ/PSi NPs combined with HBO group. The viability of hypoxia-induced glioma C6 cells was decreased and cell cycle was arrested at G2/M phase in response to TMZ/PSi NPs treatment with HBO compared with continuous treatment with hypoxia.
CONCLUSION: The combinational treatment of TMZ/PSi NPs and HBO could be a promising therapeutic strategy for glioma.
