Multiwalled carbon nanotubes (MWCNTs) are suspected lung carcinogens because their shape and size are similar to asbestos. Various MWCNT types are manufactured; however, only MWNT-7 is classified into Group 2B by The International Agency for Research on Cancer. MWNT-7’s carcinogenicity is strongly related to inflammatory reactions.  In this study, to investigate in vivo MWNT-7 genotoxicity on various endpoints, authors attempted to develop a lung micronucleus assay through ex vivo culture targeting the cellular fraction of Clara cells and alveolar Type II (AT-II) cells, known as the initiating cells of lung cancer.

PIG-A gene mutation as a genotoxicity biomarker in polycyclic aromatic hydrocarbon-exposed barbecue workers

Yiyi Cao, Jing Xi, Chuanxi Tang, Ziying Yang, Weiying Liu, Xinyue You, Nannan Feng, Xin Yu Zhang, Jingui Wu, Yingxin Yu & Yang Luan

The PIG-A gene mutation assay is a valuable tool for measuring in vivo gene mutations in blood cells. The human PIG-A assay, used as a potential genotoxicity biomarker, is minimally invasive, sensitive, and cost-efficient; however, the relationship between carcinogen exposure and PIG-A mutations is not well understood.
Authors investigated the genotoxic effect of red blood cells using PIG-A assay and lymphocyte cytokinesis-block micronucleus test in barbecue restaurant workers (N = 70) exposed to polycyclic aromatic hydrocarbons (PAHs) and self-identified healthy control subjects (N = 56). Urinary PAH metabolites were measured to evaluate internal exposure levels.

About the Editor

New Content Item

Masami Yamada studied bacterial genetics and got a PhD degree from Osaka University. Since 1990, using genetic engineering techniques, she has constructed many strains from standard tester strains for the Ames test at the National Institute of Health Sciences, Tokyo. Such strains are useful for research fields on environmental mutagens.
Strain requests come to her every year from domestic, Asia, Europe, North America, South America, and other countries. Currently, she teaches Biology and Genetic Engineering at National Defense Academy of Japan.

About JEMS
The mission of the Japanese Environmental Mutagen and Genome Society (JEMS) is to discover how environmental mutagens affect all organisms, and to promote and apply this knowledge to protect human health and our environment. JEMS was founded in 1972, and since then the society has hosted annual conferences and open symposia on timely topics. The society is a member of the Asian Association of the Environmental Mutagen Societies and the International Association of Environmental Mutagenesis and Genomics Societies.

Aims and scope

Genes and Environment is an open-access, peer-reviewed journal that aims to accelerate communications among global scientists working in the fields of genes and environment. The journal welcomes papers dealing with those topics that are relevant to the environment, such as mutagenesis and carcinogenesis, genomics and epigenetics, molecular epidemiology and genetic toxicology, and regulatory sciences.
