Background: Fe(II)-dependent dioxygenases regulate epigenetic control, collagen maturation, and HIF degradation.Results: Iron chelation by fluoroquinolone antibiotics results in DNA and histone hypermethylation, suppression of collagen prolyl hydroxylation, and inhibition of HIF mRNA translation.Conclusion: Dioxygenase inhibition may explain renal toxicity and tendinopathy side effects of fluoroquinolones.Significance: This study suggests mechanisms for obscure fluoroquinolone-associated side effects and possible novel applications of these antibiotics as HIF antagonists.
