Conclusion
the designed Gem gated biodegradable nanosystem is expected to provide an alternative way of improving antitumor efficacy by down-regulation of ECM levels and offers a passive-targeted therapy for pancreatic cancer treatment.
Methods
A biodegradable nanoplatform based on hollow mesoporous organosilica nanoparticle (HMON) was designed as an effective delivery system for pirfenidone (PFD) to overcome the challenges in pancreatic tumor treatment. By varying pH producing a mildly acidic environment to emulate tumor cells,
Results
The in vitro and in vivo immunocytochemistry evaluations demonstrated an excellent ECM regulation efficacy of the nanoplatform and therefore the improved penetration of drug into the cells. The technique employed was especially enhanced when mediated with ultrasound target microbubble destruction (UTMD). Evaluations culminated with pancreatic cancer bearing mice and demonstrated therapeutic efficacy, good biodegradability, and negligible systemic toxicity.
