工作总结:硫酸钴导致更高的发病率 雄性和雌性小鼠的肺泡/细支气管腺瘤和癌 与对照组相比,暴露于不同浓度的硫酸钴。 对来自肺肿瘤的DNA样本进行了测序,以确定其在 K-ras基因。检测到K-ras基因外显子2存在独特的点突变。 该项目的未来工作包括确定 潜在的独特突变和基因改变的特征 可能与人类暴露相关的肿瘤抑制基因。这个 这些研究的第一部分的结果发表在NTP上 1996年12月成立了复审委员会。
英文摘要
Summary of Work: Cobalt sulfate induced a higher incidence of alveolar/bronchiolar adenomas and carcinomas in male and female mice exposed to various concentrations of cobalt sulfate compared to controls. DNA samples from lung neoplasms were sequenced for point mutations in the K-ras gene. Unique point mutations were detected in K-ras exon 2. Future work on this project includes determining the mechanism for the unique mutations and characterizing genetic alterations in potential tumor suppressor genes which may be relevant to human exposure. The findings for the first part of these studies were printed in the NTP Review Board in December 1996.
