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.
Macrophages are known to play an important role in hepatocyte mediated liver regeneration by secreting inflammatory mediators. However, there is little information available on the role of resident macrophages in oval cell mediated liver regeneration. In the present study we
Pretreatment of mesenchymal stem cells (MSCs) with melatonin (Mel) improves their potential therapeutic effect on chronic diseases and cancers. However, this preconditioning strategy may direct the effect of Mel toward MSCs alone and deprive cancer cells of the oncostatic effect
Site-specific delivery of chemotherapeutics specifically to neoplastic hepatocytes without affecting normal hepatocytes should be a focus for potential therapeutic management of hepatocellular carcinoma (HCC). The aptamer TLS 9a with phosphorothioate backbone modifications (L5) has not been explored so far for
Journal of the American Chemical Society, 133(32), 12600-12607 (2011-07-15)
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) 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
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.
