Fusobacterium nucleatum promotes esophageal squamous cell carcinoma progression and chemoresistance by enhancing the secretion of chemotherapy-induced senescence-associated secretory phenotype via activation of DNA damage response pathway.

ABSTRACT: Senescence frequently occurs in cancer cells in response to chemotherapy (called therapy-induced senescence). Senescent cells can exert paracrine effects through the senescence-associated secretory phenotype (SASP) promoting cancer recurrence and chemoresistance. The altered gut microbiota has been closely associated with cancer progression through the direct interaction with cancer cells. However, little is known about the relationship between the gut microbiota and therapy-induced senescent cells. This study aimed to explore the impact of the gut microbiota on therapy-induced senescent cells and the SASP. We found that esophageal squamous cell carcinoma (ESCC) cells were induced into senescence following platinum-based chemotherapy, accompanied by the secretion of a robust SASP. Furtherm
