The Carcinogenicity of Chromium [PDF]
Environmental Health Perspectives, 1981 The carcinogenicity of chromium compounds is reviewed with specific attention to the gaps in knowledge for risk estimation and research needs. The most important problems at present are whether trivalent chromium compounds cause cancer, and whether there is a difference in cancer causing effects between the soluble and the slightly soluble hexavalent ...

Are there thresholds for carcinogens carcinogenicity?
Mycotoxins, 2008 魚や肉などの焼けこげに含まれている2-amino-3,8-dimethylimidazo[4,5-f ] quinoxaline（MeIQx）のラット肝臓における低用量発がん性を中期発がん性試験法で検討した．その結果，MeIQx?DNA 付加体形成は微量からみられ，より高い用量で8-hydroxy-2′-deoxyquanosine 形成，lacI 遺伝子変異，イニシエーション活性等が誘発された．また，肝臓の前腫瘍性病変であるglutahione S-transferase placental（GST-P）陽性細胞巣は，さらにより高い用量で誘発された．N- ニトロソ化合物であるN-nitrosodiethylamine やN-nitrosodimethylamine でもGST-P ...

Cytochromes P450 are Expressed in Proliferating Cells in Barrett's Metaplasia
Neoplasia: An International Journal for Oncology Research, 1999 The expression of cytochromes P450 (CYP) in Barrett's esophagus and esophageal squamous mucosa was investigated. Esophagectomy specimens from 23 patients were examined for CYP expression of CYP1A2, CYP3A4, CYP2C9/10, and CYP2E1 by immunohistochemical ...
