N-(2-Fluorenyl)acetamide (2-Acetamidofluorene, 2-AAF), a genotoxic carcinogen, is used to induce liver cancer in animal models such as the 2-AAF/partial hepatectomy rat. 2-AAF may be used to study the mechanism of liver carcinogenesis and as a reference material during its identification or quantitation.
Biochem/physiol Actions
A genotoxic carcinogen that is used to model liver carcinogenesis in rat. When N-hydroxylated by cytochrome CYP1A2 in the liver, 2-AAF forms adducts with DNA and is tumorigenic in liver and bladder.

Water-soluble conjugated polymers with controlled molecular weight characteristics, absence of ionic groups, high emission quantum yields, and end groups capable of selective reactions of wide scope are desirable for improving their performance in various applications and, in particular, fluorescent biosensor

Nucleotide excision repair (NER) removes lesions caused by environmental mutagens or UV light from DNA. A hallmark of NER is the extraordinarily wide substrate specificity, raising the question of how one set of proteins is able to recognize structurally diverse
Nucleotide excision repair (NER) efficiencies of DNA lesions can vary by orders of magnitude, for reasons that remain unclear. An example is the pair of N-(2'-deoxyguanosin-8-yl)-2-aminofluorene (dG-C8-AF) and N-(2'-deoxyguanosin-8-yl)-2-acetylaminofluorene (dG-C8-AAF) adducts that differ by a single acetyl group. The NER

It is known that excessive hepatocellular apoptosis is a typical characteristic of hepatic disease, and is regulated by the mammalian target of rapamycin (mTOR) signaling pathway. As the main active component of Kudzu (Pueraria lobata) roots, which is frequently used
Hepatic oval cells are likely to be activated during advanced stage of liver fibrosis to reconstruct damaged hepatic tissue. However, their scarcity, difficulties in isolation, and in vitro expansion hampered their transplantation in fibrotic liver. This study was aimed to
DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.
Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.
