Anti-tumor principles from Nigella sativa and saffron (Crocus sativus) on chemical carcinogenesis
Roles of cytochrome P450 enzymes in chemical carcinogenesis
and cancer chemotherapy.
He chaired a number of federal committees and task forces, including the development and implementation of the Technology Transfer Act of 1986 and the White House Task Force on Chemical Carcinogenesis
Although assumed, proof of the direct emergence of epithelial CSCs from an NSC population is not available, and the identity of the cells that acquire the molecular lesions initiating chemical carcinogenesis
remains undefined (Perez-Losada and Balmain 2003).
In Chapter six the author missed a good opportunity to discuss biochemical principles in more detail such processes like mutagenesis, chemical carcinogenesis
, teratogenesis and immunotoxicity, which are fundamental in toxicology.
They were instead designed to assist epidemiologists in making inductive inferences about the causal relationship of observed associations or, in the language of chemical carcinogenesis
, as an aid in addressing the question, "Does a chemical exposure cause cancer?
Understanding what modulates changes in DNA methylation during malignant transformation is a key issue in chemical carcinogenesis
Mice deficient in COX-2 develop 75% fewer tumors than their wild type littermates when subjected to a 9,10-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate two-stage chemical carcinogenesis
protocol (Tiano et al.
Indeed, gestation is a period of high sensitivity to chemical carcinogenesis
in general in both rodents and probably humans (Anderson et al.
A critical review of experiments in chemical carcinogenesis
using newborn animals.
In 1984 the NTP Board of Scientific Counselor's Ad Hoc Panel on Chemical Carcinogenesis
Testing and Evaluation report recommended that the NTP "establish a goal of better understanding mechanisms by developing a battery of short-term tests that measures the widest possible number of end points (including promotion, transformation, and chemical interaction with oncogenes)" (NTP 1984).
