Background:

• Conventional prostate cancer therapies exhibit limitations such as nonspecific toxicity and multi-drug resistance.
• Nanoparticle-based small interfering RNA (siRNA) therapeutics are being developed to overcome these challenges.
• Existing siRNA therapeutics face hurdles including ineffective delivery, immune stimulation, and limited understanding of nano-bio interactions.

Purpose of the Study:

• To review recent advancements in nanoparticle-mediated siRNA delivery systems for prostate cancer treatment.
• To explore the potential of co-delivery strategies combining chemotherapy drugs with siRNA for enhanced prostate cancer therapy.

Main Methods:

• Comprehensive literature review of nanoparticle-based siRNA delivery systems.
• Analysis of polymeric, lipid, specific, and rigid nanoparticle carriers.
• Evaluation of combinational therapy approaches using siRNA and chemotherapy.

Main Results:

• Various nanoparticle systems show promise for targeted siRNA delivery in prostate cancer.
• Co-delivery strategies represent a robust approach for combinational prostate cancer therapy.
• Advances in nanoparticle design and manufacturing are crucial for clinical translation.

Conclusions:

• Nanoparticle-mediated siRNA delivery holds significant potential for improving prostate cancer therapeutics.
• Further research into nano-bio interactions and overcoming manufacturing/clinical translation barriers is essential.
• Combinational therapy using co-delivery systems offers a promising avenue for overcoming treatment resistance.
