    ..The data also suggest that Cyp6a2 and Cyp6a8 overexpression in the 91-R and MHIII-D23 strains is more likely due to mutation in the repressor locus (or loci) rather than in the cis-regulatory sequences of the Cyp6a2 and Cyp6a8 genes. ..

  8. Tsai J, Yan R, McKee B. Homolog pairing and sister chromatid cohesion in heterochromatin in Drosophila male meiosis I. Chromosoma. 2011;120:335-51 pubmed publisher
    ..This suggests that meiotic sister chromatid cohesion is incomplete within heterochromatin and may occur at specific preferential sites. ..
  9. Dombrowski S, Krishnan R, Witte M, Maitra S, Diesing C, Waters L, et al. Constitutive and barbital-induced expression of the Cyp6a2 allele of a high producer strain of CYP6A2 in the genetic background of a low producer strain. Gene. 1998;221:69-77 pubmed
    ..Possible reasons for low constitutive expression of the endogenous Cyp6a2 gene and moderate level of expression of the Cyp6a2-91 R allele in the ry506 genetic background are discussed. ..

    ..These results suggest that D-jun acts as a negative regulator, and caffeine induction of Cyp6a8 and Cyp6a2 genes is mediated by the upregulation of cAMP pathway and downregulation of the D-JUN protein level. ..
