  1. Ray A, Ray B. Persistent expression of serum amyloid A during experimentally induced chronic inflammatory condition in rabbit involves differential activation of SAF, NF-kappa B, and C/EBP transcription factors. J Immunol. 1999;163:2143-50 pubmed
    ..This result suggested that C/EBP, SAF, and NF-kappa B are required for transient acute phase induction of SAA whereas SAF and NF-kappa B activities are necessary for persistent SAA expression during chronic inflammatory conditions. ..

    ..PKA-mediated phosphorylation increases transcriptional activity of SAF-1 by unmasking the DNA-binding domain. ..

  5. Ray A, Shakya A, Ray B. Inflammation-responsive transcription factors SAF-1 and c-Jun/c-Fos promote canine MMP-1 gene expression. Biochim Biophys Acta. 2005;1732:53-61 pubmed
    ..These results show that induction and activation of AP-1 and SAF-1 transcription factors are involved in the regulation of MMP-1 expression in the chondrocytes which could be used as therapeutic targets to combat pathogenesis of OA. ..
  6. Ray A, Shakya A, Kumar D, Benson M, Ray B. Inflammation-responsive transcription factor SAF-1 activity is linked to the development of amyloid A amyloidosis. J Immunol. 2006;177:2601-9 pubmed
    ..Together, these results provide direct evidence that SAF-1 plays a key role in the development of AA amyloidosis, a consequence of chronic inflammation. ..
