Oxidative Stress in the Carcinogenicity of Chemical Carcinogens [PDF]

open access: yesCancers, 2013
This review highlights several in vivo studies utilizing non-genotoxic and genotoxic chemical carcinogens, and the mechanisms of their high and low dose carcinogenicities with respect to formation of oxidative stress. Here, we survey the examples and discuss possible mechanisms of hormetic effects with cytochrome P450 inducers, such as phenobarbital, a-

Tauroursodeoxycholic acid dampens oncogenic apoptosis induced by endoplasmic reticulum stress during hepatocarcinogen exposure [PDF]

open access: yes, 2015
Hepatocellular carcinoma (HCC) is characterized by the accumulation of unfolded proteins in the endoplasmic reticulum (ER), which activates the unfolded protein response (UPR).

Cytochromes P450 are Expressed in Proliferating Cells in Barrett's Metaplasia

open access: yesNeoplasia: An International Journal for Oncology Research, 1999
The expression of cytochromes P450 (CYP) in Barrett's esophagus and esophageal squamous mucosa was investigated. Esophagectomy specimens from 23 patients were examined for CYP expression of CYP1A2, CYP3A4, CYP2C9/10, and CYP2E1 by immunohistochemical ...

Changes in miR-124-1, miR-212, miR-132, miR-134, and miR-155 Expression Patterns after 7,12-Dimethylbenz(a)anthracene Treatment in CBA/Ca Mice

open access: yesCells, 2022
Specific gene and miRNA expression patterns are potential early biomarkers of harmful environmental carcinogen exposures. The aim of our research was to develop an assay panel by using several miRNAs for the rapid screening of potential carcinogens.

Carcinogenic Tattoos?

open access: yesEpidemiology, Biostatistics, and Public Health, 2022
Millions of people have tattoos. The systemic effects of tattoo colorants (TCs) are mostly unknown. Several tattoos are on the market, which contain carcinogenic compounds such as poly aromatic hydrocarbons compounds or carcinogenic aromatic amines.

The role of cytochrome P450 enzymes in carcinogen activation and detoxication: an in vivo–in vitro paradox

open access: yesCarcinogenesis, 2018
Cytochrome P450 enzyme systems have been widely used in vitro to determine the pathways of activation of procarcinogens, but paradoxically, these same enzymes can play a more predominant role in carcinogen detoxification in vivo.

An Electrochemical DNA Biosensor for Carcinogenicity of Anticancer Compounds Based on Competition between Methylene Blue and Oligonucleotides

open access: yesSensors, 2019
A toxicity electrochemical DNA biosensor has been constructed for the detection of carcinogens using 24 base guanine DNA rich single stranded DNA, and methylene blue (MB) as the electroactive indicator.

Glass Particles in the Nasal Cavity for 30 Years and Squamous Cell Carcinoma: Is There a Relationship?

open access: yesTurkish Archives of Otorhinolaryngology, 2022
Nasal cavity tumors constitute a very small part of head and neck malignancies. Although paranasal sinus tumors due to the presence of backward foreign bodies, neoplasms of nasal cavity associated with a foreign body are extremely rare.
