Gut microbiota controlling radiation-induced enteritis and intestinal regeneration

Area of Science:

• Oncology
• Gastroenterology
• Microbiology

Background:

• Radiotherapy is a common cancer treatment but causes toxicity in healthy tissues, particularly the bowel.
• Radiation-induced enteritis significantly impacts cancer patients' quality of life due to morbidity and mortality.
• The gut microbiome plays a crucial role in maintaining gut health and responding to injury.

Purpose of the Study:

• To critically review the key factors influencing the gut microenvironment during homeostasis, disease, and injury.
• To focus on the role of gut microbial metabolites and microorganisms in epithelial regeneration following radiation damage.

Main Methods:

• Literature review of studies on radiation-induced enteritis and gut microbiome.
• Analysis of research on gut microenvironment modulation.
• Focus on microbial metabolites and microorganisms influencing epithelial repair.

Main Results:

• The gut microenvironment is dynamic and influenced by various factors during radiation injury.
• Gut microbial metabolites and specific microorganisms are critical in promoting or hindering epithelial regeneration.
• Understanding these interactions is key to mitigating radiation-induced enteritis.

Conclusions:

• Modulating the gut microenvironment through microbial interventions holds therapeutic potential for radiation-induced enteritis.
• Targeting gut microbial metabolites and microorganisms can enhance gut epithelial repair after radiotherapy.
• Further research is needed to translate these findings into clinical practice for cancer patients.
