This study investigated how recurrent sleep deprivation influences colon cancer progression and immune responses, with particular attention to the role of Galectin\u20109. A murine CT26 colon carcinoma model was established to examine tumor growth dynamics and host immune responses under scheduled cycles of sleep deprivation. For tumor implantation, mice were injected with CT26 cells stably transduced to overexpress Galectin\u20109 (Gal\u20109 OE) or with vector\u2010transduced wild\u2010type control CT26 cells. Immune phenotyping was conducted using flow cytometry, and chromatin immunoprecipitation assays were employed to assess regulatory mechanisms at the Gal\u20109 promoter. To further evaluate therapeutic potential, a bispecific CD3\/Gal\u20109 antibody was administered to determine its capacity to restore immune activity and restrain tumor growth under sleep\u2010disrupted conditions. Sleep deprivation significantly increased tumor burden and induced immune suppression, characterized by elevated Gal\u20109 expression, increased regulatory T cell infiltration, and diminished cytotoxic T cell activity. Treatment with the bispecific CD3\/Gal\u20109 antibody reversed these effects, reducing tumor growth and enhancing antitumor immune responses in Gal\u20109\u2010overexpressing tumors. Sleep deprivation promotes immune evasion and reduces ICB efficacy in colorectal cancer through Gal\u20109\u2010mediated pathways. Targeting Gal\u20109 with bispecific antibodies may represent a viable approach to restore immune competence in sleep\u2010disrupted conditions. These findings highlight the importance of sleep quality in cancer progression and suggest that integrating lifestyle interventions with immunotherapy may improve clinical outcomes.<\/jats:p>","DOI":"10.1002\/jbt.70837","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T12:09:04Z","timestamp":1778846944000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sleep
