Disease relevance of Polk

  • Recently several chronic toxicity/carcinogenicity studies of di-isononyl phthalate (DINP) have been reported [1].
 

High impact information on Polk

 

Biological context of Polk

  • Mutation rates at two expanded simple tandem repeat (ESTR) loci were studied in the germline of DNA polymerase kappa (Polkappa(-/-)) deficient mice [6].
 

Anatomical context of Polk

  • The short-term hepatic effects of DINP (CAS 68515-48-0, designated DINP-1) in rats and mice were evaluated at tumorigenic and nontumorigenic doses from previous chronic studies [7].
 

Associations of Polk with chemical compounds

  • To extend these observations, three other commercial phthalate ester plasticizers, di-isononyl phthalate (DINP), di-isohexyl phthalate (DIHP), and butyl benzyl phthalate (BBP), were assessed using the same protocol [8].
  • In summary, treatment with DEHP, DINP, DIHP, and BBP did not result in significant elevations in total serum IgE, IL-4, or IL-13 [8].
  • The esters tested were: dimethyl phthalate (DMP), di-n-butyl phthalate (DBP), butyl benzyl phthalate (BBP), di-¿n-hexyl, n-octyl, n-decyl¿ phthalate (610P), di-isononyl phthalate (DINP), di-¿heptyl, nonyl, undecyl¿ phthalate (711P), di-isodecyl phthalate (DIDP) and di-undecyl phthalate (DUP) [9].
 

Other interactions of Polk

  • During the autumn of 1993, a focal outbreak was reported from Lee (5 cases) and Collier (3) Counties in southwest Florida. During the autumn of 1997, sporadic transmission to nine humans was reported from five Florida counties (Brevard [1 case], Polk [3], Charlotte [1], Lee [2], and Palm Beach [2]) [10].
  • The absence of DNA polymerase kappa does not affect somatic hypermutation of the mouse immunoglobulin heavy chain gene [11].
