CXCL14 and acute respiratory distress syndrome: For instance, the sequencing results revealed several differentially expressed genes such as serpin peptidase inhibitor (SERPINB4), thymidine kinase 1 (TK1), CXCL14, and Krüppel-like factor 4 (KLF4) of unclear significance in ARDS but which could represent meaningful off-target effects.
