Gut microbiota regulating programmed cell death: Impacts on cancer immunotherapy, mechanisms, therapeutic responses...

Area of Science:

• Oncology
• Microbiology
• Immunology

Background:

• Cancer is a leading global cause of death, presenting a significant healthcare burden.
• The host gut microbiota is a dynamic ecosystem increasingly recognized for its role in cancer progression and treatment response.
• Interactions between the gut microbiota and the host immune system critically impact tumor development and therapeutic outcomes.

Purpose of the Study:

• To systematically review the mechanisms by which gut microbiota regulates programmed cell death (PCD) in cancer.
• To analyze key molecular pathways involved in microbiota-mediated regulation of PCD and cancer.
• To summarize novel strategies for enhancing cancer therapy by modulating the gut microbiota.

Main Methods:

• Systematic review of existing literature on gut microbiota, programmed cell death, and cancer therapy.
• Analysis of molecular pathways linking gut microbiota composition to host immune responses and cancer cell death.
• Synthesis of current research on microbiota-targeted interventions for cancer treatment.

Main Results:

• Gut microbiota influences cancer progression and response to therapy through modulation of PCD.
• Key immune signaling pathways are regulated by the gut microbiota, affecting tumor microenvironment and treatment efficacy.
• Microbiota composition is a critical determinant of programmed cell death induction and evasion in cancer.

Conclusions:

• The gut microbiota plays a pivotal role in cancer pathogenesis and response to antitumor therapies.
• Understanding microbiota-driven PCD regulation is essential for developing effective cancer treatments.
• Targeting the gut microbiota presents a promising avenue for reducing treatment resistance and personalizing cancer care.
