樟树籽仁油的遗传毒性评价

open access: yesZhongguo youzhi
为评价樟树籽仁油的食用安全性,通过细菌回复突变试验、体外哺乳类细胞TK基因突变试验及哺乳动物红细胞微核试验探究樟树籽仁油的致突变和潜在致癌作用。结果表明:樟树籽仁油对组氨酸缺陷型鼠伤寒沙门氏菌TA1535、TA97、TA98、TA100、TA102均无致突变作用;樟树籽仁油未抑制L5178Y小鼠淋巴瘤细胞的生长,对体外哺乳类细胞TK基因无致突变作用;樟树籽仁油未导致小鼠细胞微核率上升,对哺乳动物红细胞无致突变作用,无遗传毒性。综上,樟树籽仁油无细胞致突变和潜在致癌作用,没有遗传毒性,具有一定的食用安全性。

Identification of Hot and Cold Regions for Mutagenesis in the Escherichia coli tdk Gene: A Catalog of Mutational Sites

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT We constructed a catalog of mutational sites in the tdk gene of Escherichia coli that consists of 378 different base pair substitutions at 245 different sites (base pairs). This allows us to examine the tendency of different sub‐regions of the gene to be more or less prone to mutations when compared with other sub‐regions.
