    DNA Repair (Amst) 4:1457-62. 2005
    ..We propose that physiological relevant UV doses should be determined for each target cell type prior to studying UV-induced responses and that p21(CDKN1A) is indeed critical for cell cycle arrest in cells that survive UV-irradiation...
  2. ncbi request reprint Xeroderma pigmentosum group E and DDB2, a smaller subunit of damage-specific DNA binding protein: proposed classification of xeroderma pigmentosum, Cockayne syndrome, and ultraviolet-sensitive syndrome
    Toshiki Itoh
    Department of Pathology, The University of Iowa, Carver College of Medicine, 200 Hawkins Dr, Iowa City, IA 52242, USA
    J Dermatol Sci 41:87-96. 2006
    ..These phenotypes are unique to XP-E because other XP groups show normal (XP-V) or hypersensitivity (XP-A, B, C, D, F, and G) to UV-irradiation. Thus XP-E is defined as a skin cancer prone disease with unique resistance to UV-irradiation...

    Toshiki Itoh
    Department of Pathology, The University of Iowa, Carver College of Medicine, Iowa City, IA 52242, USA
    Hum Mol Genet 16:1578-86. 2007
    ..These results demonstrate that in whole animals as in cultured cells Ddb2 can regulate apoptosis and tumor incidence...

    Toshiki Itoh
    Division of Biochemistry and Molecular Biology, Department of Molecular and Cell Biology, University of California, Berkeley, California 94720 3202, USA
    Mol Cell Biol 23:7540-53. 2003
    ..We propose that both before and after UV irradiation, DDB2 directly regulates p53 levels, while DDB2 expression is itself regulated by p53...

    Toshiki Itoh
    Divisions of Biochemistry and Molecular Biology, Department of Molecular and Cell Biology, University of California, Berkeley, CA 94720 3202, USA
    Proc Natl Acad Sci U S A 101:2052-7. 2004
    ..In sum, these results demonstrate that DDB2 is well conserved between humans and mice and functions as a tumor suppressor, at least in part, by controlling p53-mediated apoptosis after UV-irradiation...

    Nat Cell Biol 6:420-6. 2004
    ..These results suggest that one of the products of PI(3)K, PtdIns(3,4,5)P(3), recruits WAVE2 to the polarized membrane and that this recruitment is essential for lamellipodium formation at the leading edge...
