KLF4 downregulates FGF21 to activate inflammatory injury and oxidative stress of LPS‑induced ATDC5 cells via SIRT1/NF‑κB/p53 signaling.

ABSTRACT: Ankylosing spondylitis (AS) is a chronic inflammatory disease. Transcriptional regulation of fibroblast growth factor 21 (FGF21) by the transcription factor Krüppel‑like factor 4 (KLF4) serves an important role in chronic inflammatory disease. However, to the best of our knowledge, the role of both these factors in AS has not been previously reported. In the present study, ATDC5 cells were induced by lipopolysaccharide (LPS) to establish an AS inflammatory injury model. The expression levels of FGF21 and KLF4 were detected using reverse transcription‑quantitative PCR and western blotting. Cell transfection was performed to alter the expression levels of KLF4 and FGF21. Subsequently, the regulatory effects and mechanisms underlying KLF4 and FGF21 on oxidative stress and inflammation in AS w
