File Description [top]

CANCERLIT® is produced by the International Cancer Research DataBank Branch (ICRDB) of the U.S. National Cancer Institute. The database consists of bibliographic records referencing cancer research publications dating from 1963 to the present. Most records contain abstracts, and all records contain citation information and additional descriptive fields such as document type and language. Beginning with the June 1983 CANCERLIT update, records from the MEDLINE® database dealing with cancer topics have been added to CANCERLIT.

Records added to CANCERLIT since January 1980 are indexed using the U.S. National Library of Medicine (NLM) Medical Subject Heading (MeSH®). The CANCERLIT records with MeSH descriptors are updated annually with the current version of MeSH headings. An online thesaurus is available to aid in locating MeSH descriptors. All records added before June 1983 have abstracts; approximately 75% of the records added since June 1983 have abstracts.



Tips [top]

USE THE (L) OPERATOR

to link descriptors and subheadings:

     S PROTEIN KINASES(L)ME
      S CELL DIVISION(L)DRUG EFFECTS

USE EXPLODE (!)

to search narrower descriptors in the MeSH vocabulary:

     S TUMOR CELLS, CULTURED!

USE THE ONLINE THESAURUS

to check and select MeSH thesaurus terms:

     E (DNA DAMAGE)

USE MAP

to take CAS® Registry Numbers to another file:

     MAP RN TEMP S1

Subject Coverage [top]

  • All aspects of experimental and clinical cancer therapy
  • Biochemistry, immunology, physiology, and other biology of cancer, both in vivo and in vitro
  • Chemical, viral, and other agents that cause cancer
  • Mechanisms of carcinogenesis
  • Studies of mutagens, mutagen testing, and growth factors or other agents that stimulate cell division


Sources [top]

CANCERLIT includes indexing for articles from more than 3,500 journals; approximatley 200 core journals contribute a large percentage of the citations. Selected records are taken from the MEDLINE database beginning in June 1983. In addition, proceedings of meetings, government reports, symposia reports, selected monographs, and theses are also abstracted for inclusion in the database.

  /AB    Genistein,  a  natural  isoflavone  found in soybeans, exerts a number of 
    biological actions suggesting that it may have a role in cancer prevention. 
    We  have  previously  shown that it potently inhibits OCM-1 melanoma  cell 
    proliferation  by  inducing  a  G(2)  cell  cycle arrest. Here we show that 
    genistein  exerts  this  effect  by  impairing  the Cdc25C-dependent Tyr-15 
    dephosphorylation of Cdk1, as the overexpression of this phosphatase allows 
    the   cells   to  escape  G(2)  arrest  and  enter  an  abnormal  chromatin 
    condensation  stage.  Caffeine totally overrides the genistein-induced G(2) 
    arrest,  whereas  the  block  caused  by etoposide is not bypassed and that 
    caused  by  adriamycin  is  only  partially  abolished. We also report that 
    genistein  activates  the  checkpoint kinase Chk2 as efficiently as the two 
    genotoxic agents and that caffeine may counteract the activation of Chk2 by 
    genistein  but  not  by  etoposide.  In  contrast,  caffeine  abolishes the 
    accumulation  of  p53  caused  by  all  the  compounds. Wortmannin does not 
    suppress  the  Chk2 activation in any situation, suggesting that the ataxia 
    telangiectasia-mutated  kinase is not involved in this regulation. Finally, 
    unlike  etoposide and adriamycin, genistein induces only a weak response in 
    terms  of  DNA damage in OCM-1 cells. Taken together, these results suggest 
    that  the  G(2)  checkpoints  activated  by genistein and the two genotoxic 
    agents involve different pathways.
