Inorganic Nanocarriers Overcoming Multidrug Resistance for Cancer Theranostics

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Oncology

Background:

• Cancer multidrug resistance (MDR) is a major challenge in chemotherapy and radiotherapy, leading to treatment failure.
• Conventional anticancer agents and imaging probes have limitations in targeting specific cancer cells.
• Advanced drug delivery platforms are needed to overcome MDR and enhance therapeutic efficacy.

Purpose of the Study:

• To review the mechanisms of cancer MDR.
• To summarize recent advances in applying inorganic nanocarriers for MDR cancer imaging and therapy.
• To highlight the potential of inorganic nanocarriers in overcoming MDR and guiding clinical translation.

Main Methods:

• Review of existing literature on cancer MDR mechanisms.
• Analysis of studies utilizing inorganic nanocarriers for theranostic applications in MDR cancers.
• Exploration of synergistic therapeutic approaches combined with nanocarriers (e.g., RNA interference, thermal therapy).

Main Results:

• Inorganic nanocarriers can achieve synergistic therapeutic effects, enhancing cancer cell killing in MDR models.
• These nanocarriers offer imaging capabilities for monitoring treatment response and understanding MDR mechanisms.
• Combined therapeutic strategies show enhanced efficacy against MDR cancer cells.

Conclusions:

• Inorganic nanocarriers represent a promising platform for overcoming cancer MDR.
• They enable real-time molecular imaging to track therapeutic processes.
• Further research into nanocarrier design holds potential for clinical translation in treating MDR cancers.
