Abstract:
Photodynamic therapy (PDT) is a noninvasive and effective local treatment for cancers that produces selective damage to target tissues and cells. However, PDT alone is unlikely to completely inhibit tumor metastasis and/or local tumor recurrence. RNA interference (RNAi) is a phenomenon of gene silencing mediated by exogenous or endogenous double-stranded RNA (dsRNA). RNAi has entered a golden period of development, with the approval of four treatments employing RNAi. PDT in combination with RNAi therapy to inhibit related targets has been a research hotspot, with better clinical outcomes than monotherapy. In this review, the progress of PDT and small interfering RNA (siRNA) targeting different genes is discussed, while the achievements of the combined immunotherapy are reviewed.
Insights
Photodynamic therapy combined with RNA interference offers improved cancer treatment by silencing genes. This combination therapy shows better outcomes than monotherapy for inhibiting tumor metastasis and recurrence.
Area of Science:
- Oncology
- Biotechnology
- Molecular Biology
Background:
- Photodynamic therapy (PDT) is a noninvasive cancer treatment causing selective cell damage.
- PDT monotherapy has limitations in preventing tumor metastasis and recurrence.
- RNA interference (RNAi) is a gene-silencing mechanism with approved therapeutic applications.
Purpose of the Study:
- To review the progress of combining Photodynamic Therapy (PDT) with RNA interference (RNAi) for cancer treatment.
- To discuss the efficacy of small interfering RNA (siRNA) targeting various genes within combined PDT protocols.
- To summarize the achievements of this combined immunotherapeutic approach.
Main Methods:
- Review of existing literature on PDT and RNAi (siRNA) in cancer therapy.
- Analysis of studies investigating combined PDT-RNAi strategies.
- Evaluation of clinical outcomes reported for combined versus monotherapy.
Main Results:
- Combined PDT and RNAi therapy is a significant research area.
- This combination demonstrates superior clinical outcomes compared to monotherapy.
- Specific gene targets for siRNA in conjunction with PDT are being explored.
Conclusions:
