Cell cycle progression, but not genotoxic activity, mainly contributes to citrinin-induced renal carcinogenesis.
Citrinin (CTN) is a food-contaminating mycotoxin that efficiently induces renal tumors in rats. However, the modes of carcinogenic action are still unknown, preventing assessment of the risks of CTN… Expand

Ochratoxin A induces DNA double-strand breaks and large deletion mutations in the carcinogenic target site of gpt delta rats.
Ochratoxin A (OTA) is a carcinogen targeting proximal tubules at the renal outer medulla (ROM) in rodents. We previously reported that OTA increased mutant frequencies of the red/gam gene (Spi(-)),… Expand

In vivo genotoxicity of Ginkgo biloba extract in gpt delta mice and constitutive androstane receptor knockout mice.
The National Toxicology Program study of Ginkgo biloba extract (GBE), a herbal supplement, reported concerns regarding genotoxicity and clear evidence of hepatocarcinogenicity and liver hypertrophy… Expand

Role of p53 in the progression from ochratoxin A-induced DNA damage to gene mutations in the kidneys of mice.
Carcinogenic doses of ochratoxin A (OTA) cause increases of mutant frequencies (MFs) of the red/gam gene (Spi(-)) in the kidneys of p53-deficient gpt delta mice, but not in p53-proficient mice. Here,… Expand

Lack of genotoxic mechanisms in early‐stage furan‐induced hepatocellular tumorigenesis in gpt delta rats
Furan has been used as an intermediate in the chemical‐manufacturing industry and has been shown to contaminate various foods. Although furan induces hepatocellular tumors in rodents, equivocal… Expand

Possible participation of oxidative stress in causation of cell proliferation and in vivo mutagenicity in kidneys of gpt delta rats treated with potassium bromate.
Clarifying the participation of oxidative stress among possible contributing factors in potassium bromate (KBrO(3))-induced carcinogenesis is of importance from the perspective of human health… Expand

Molecular mechanisms underlying ochratoxin A-induced genotoxicity: global gene expression analysis suggests induction of DNA double-strand breaks and cell cycle progression.
Ochratoxin A (OTA) is a renal carcinogen primarily affecting the S3 segment of proximal tubules in rodents. In our previous study, we reported that OTA induces reporter gene mutations, primarily… Expand

Effects of Nrf2 silencing on oxidative stress‐associated intestinal carcinogenesis in mice
To assess the risk of colorectal cancer in humans with inactivation of NRF2, Nrf2‐proficient (Nrf2+/+) and ‐deficient (Nrf2−/−) mice were exposed to potassium bromate (KBrO3) at concentrations of 750… Expand

Acrylamide induces specific DNA adduct formation and gene mutations in a carcinogenic target site, the mouse lung.
Acrylamide (AA) is a contaminant in heated foods and is carcinogenic in multiple organs of rodents. There have been many reports regarding AA-induced DNA modification and genotoxicity. However, the… Expand

Effects of p53 knockout on ochratoxin A-induced genotoxicity in p53-deficient gpt delta mice.
Ochratoxin A (OTA) is a mycotoxin produced by fungal species and is carcinogenic targeting the S3 segment of the renal proximal tubules in rodents. We previously reported that exposure of gpt delta… Expand
