Disease relevance of CDKN2B

  • Taken together, these results suggest that intragenic mutations in CDKN2A and CDKN2B occur in esophageal cancer, but that they are infrequent events [1].
  • In conjunction with our previously published data, we have identified a total of eight nucleic acid substitutions among 60 esophageal carcinomas; here, we describe one new CDKN2B nonsense mutation and one new silent CDKN2B mutation that occurred somatically [1].
  • Messenger RNA (mRNA) analysis showed that CDKN2C is expressed in all hepatoblastoma samples studied, while both CDKN2A and CDKN2B genes are not transcribed in the cancer specimens as well as in the matched normal liver tissues [2].
  • The 500 C>G polymorphism, however, was in linkage disequilibrium with approximately 50 kb apart the C>A intronic polymorphism in the CDKN2B gene (determined in 44 melanomas and 90 controls; Fisher exact test, p<0.0001) [3].
  • Genomic DNA and messenger RNA expression alterations of the CDKN2B and CDKN2 genes in esophageal squamous carcinoma cell lines [4].

Associations of CDKN2B with chemical compounds

  • Serial studies of methylation of CDKN2B and CDKN2A in relapsed acute promyelocytic leukaemia treated with arsenic trioxide [8].
  • Only G15 iron deficient rats had greater dopaminergic activity than controls as indicated by increased tyrosine hydroxylase levels, phosphorylated tyrosine hydroxylase levels, and cellular dopamine in prefrontal cortex and striatum at P15 [17].
  • Circulating testosterone levels peak in male ferrets on postnatal day P15, and mothers provide maximal anogenital stimulation (AGS) to males at this same age [18].
  • There were fewer glial cells per cross-section on day 15 and the cross-sectional areas of optic nerves were smaller on days G20, P15 and P90 in the ethanol exposed animals [19].
  • Dispersion of ABM/P-15 in sodium hyaluronate carrier (PPutty) improves the handling properties of the graft material [20].
