Autophagy manipulation as a strategy for efficient anticancer therapies: possible consequences.

Area of Science:

• Cellular Biology
• Oncology
• Immunology

Background:

• Autophagy is a cellular degradation process impacting cancer cell adaptation to stress.
• Autophagy's role in cancer is paradoxical, potentially promoting survival or triggering cell death.
• Modulating autophagy is explored as a cancer treatment strategy, often combined with other therapies.

Purpose of the Study:

• To review the benefits and drawbacks of manipulating autophagy in cancer.
• To explore autophagy's dual role in promoting cancer cell death and disabling oncogenes.
• To assess the interaction between autophagy and the immune response in cancer therapy.

Main Methods:

• Literature review of autophagy's role in cancer.
• Analysis of studies on autophagy induction and inhibition in preclinical and clinical settings.
• Evaluation of autophagy's impact on cancer cell fate and immune system interactions.

Main Results:

• Autophagy activation can promote cancer cell survival under stress but may also induce cell death.
• Inhibition of autophagy can sensitize cancer cells to conventional therapies.
• The interplay between autophagy and the immune system significantly influences therapeutic outcomes.

Conclusions:

• The decision to induce or inhibit autophagy for cancer treatment remains controversial and patient-specific.
• Targeting autophagy offers potential for cancer cell death and oncogene inactivation.
• Considering autophagy's interaction with the immune response is essential for optimizing anticancer strategies.
