Promising but preliminary

Krüppel-like factor 4 downregulation during esophageal cancer formation facilitates immune evasion and impairs immunotherapy.

Low levels of a specific protein predict immunotherapy failure across multiple cancer types, offering a potential biomarker for treatment selection.

Impaired antigen processing and presentation are critical for cancer immune evasion, but the underlying mechanism is not fully known. Extending beyond esophageal cancer, we reveal that low KLF4 levels are significantly correlated with high immunotherapy failure rates across multiple human cancer types.
