Paclitaxel (PTX) is one of the most broadly used chemotherapeutic agents for the treatment of several tumor types including ovarian, breast, and non-small cell lung cancer.

Mice were pre-treated with sodium butyrate (BuNa) for 30 days before receiving PTX. After 14 days, mice underwent to behavioral analysis and biochemical investigations of gut barrier integrity and microbiota composition. Paired evaluations of gut functions revealed that the treatment with BuNa restored PTX-induced altered gut barrier integrity, microbiota composition and food intake suggesting a gut-to-brain communication. The treatment with BuNa also ameliorated depressive- and anxiety-like behaviors induced by PTX in mice, and these effects were associated with neuroprotective and anti-inflammatory outcomes.

Abstract

Paclitaxel (PTX) is one of the most broadly used chemotherapeutic agents for the treatment of several tumor types including ovarian, breast, and non-small cell lung cancer. However, its use is limited by debilitating side effects, involving both gastrointestinal and behavioral dysfunctions. Due to growing evidence showing a link between impaired gut function and chemotherapy-associated behavioral changes, the aim of this study was to identify a novel therapeutic approach to manage PTX-induced gut and brain comorbidities. Mice were pre-treated with sodium butyrate (BuNa) for 30 days before receiving PTX. After 14 days, mice underwent to behavioral analysis and biochemical investigations of gut barrier integrity and microbiota composition. Paired evaluations of gut functions revealed that the treatment with BuNa restored PTX-induced altered gut barrier integrity, microbiota composition and food intake suggesting a gut-to-brain communication. The treatment with BuNa also ameliorated depressive- and anxiety-like behaviors induced by PTX in mice, and these effects were associated with neuroprotective and anti-inflammatory outcomes. These results propose that diet supplementation with this safe postbiotic might be considered when managing PTX-induced central side effects during cancer therapy.
