概括

多环芳 (PAH) 会导致鱼类的发育缺陷. 抑制基碳化合物受体 (AhR) 或细胞染色体P450 (CYP) 途径可以改变这些毒性作用,揭示出明显的PAH机制.

科学领域:

环境毒理学环境毒理学
发展生物学发展生物学
生态毒理学生态毒理学

背景情况:

多环芳 (PAH) 是环境污染物,已知会导致水生生物,特别是鱼类胚胎的发育异常.
造成PAH诱导的发育毒性背后的精确机制,特别是基碳化合物受体 (AhR) 和细胞染色体P450 (CYP) 途径的作用,仍然不完全理解.

研究的目的:

调查CYP1A抑制和AhR对抗对暴露于各种PAH的日本medaka (Oryzias Latipes) 胚胎发育形的影响.
阐明AhR和CYP途径在调解不同PAH的发育毒性方面的不同作用.

主要方法:

日本的梅达卡胚胎暴露于单独的,,,,,,或,或与CYP1A抑制剂piperonylbutoxide (PBO) 或AhR抗剂CH223191 (CH) 结合使用.
胚胎在显微镜下检查了形态形,包括面形,心脏缩,心周胀和脊柱曲.

主要成果:

甲 (BaA) 暴露引起了面形,同时暴露于PBO加剧了这些缺陷.
皮伦 (Pyr) 暴露导致面缺陷,心脏缩,心周胀和脊柱曲,这些因同时暴露于CH或PBO而显著减少.
兰和兰没有诱导显著的形态形.

结论:

结构多样化的PAHs可以通过不同的毒理途径在鱼类胚胎中诱导明显的发育缺陷.
AHR和CYP1A通路在调解某些PAH的发育毒性方面发挥着重要作用,根据特定的PAH结构而有不同的贡献.

Mutagenicity and Carcinogenicity

Mutagenicity and Carcinogenicity

Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
