2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is a food-derived carcinogen that is found in high temperature-cooked fish and meat.{38226} In humans, PhIP is metabolized by the cytochrome (CYP) P450 isoform CYP1A2 and conjugated by N-acetyltransferase or sulfotransferase to a metabolite that reacts with DNA to form adducts, which are directly correlated with increased risk of breast, colon, and prostate cancers.{38226,38227,38228} Chronic treatment (1 pM/L for 20 cycles) of MCF-10A cells with PhIP induces anchorage-independent cell growth and reduces cellular dependence on growth factors.{38226} It increases wild-type H-Ras gene and protein expression, which activates ERK signaling, MMP-2 and MMP-9 protein expression, and NOX1-driven production of reactive oxygen species (ROS) in vitro. In vivo, PhIP pre-treatment of MCF-10A cells increases tumor formation in a murine breast cancer xenograft model. In a CYP1A2 humanized rat model, PhIP induces formation of colon tumors with β-catenin gene mutations that hyperactivate the Wnt signaling pathway, mimicking the phenotype observed in human tumor isolates.{38228} In vivo administration of PhIP (400 ppm/week for 52 weeks) also increases the occurrence of atypical hyperplasias and carcinomas in the ventral prostate and seminal vesicles of rats.{38227}

  • A powerful effector in both the TetR and revTetR transcriptional regulator systems

    Anhydrotetracycline (hydrochloride) – 100 mg

    The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}

  • A small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state; activity is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM

    SC-1 – 1 mg

    The maintenance of embryonic stem cells in culture typically requires feeder cells and various exogenous factors found in serum. Murine embryonic stem (mES) cells can be maintained in the absence of feeder cells and serum but require the leukemia inhibitor factor (LIF) and bone morphogenic protein (BMP) to prevent differentiation and promote self-renewal. SC-1 is a small molecule activator of stem cell renewal that allows the propagation of OG2 mES cells for at least 10 passages in an undifferentiated state.{14533} The activity of SC-1 is mediated by the combined inhibition of RasGAP and ERK1 with Kd values of 98 and 212 nM, respectively.{14533} Inhibition of RasGAP increases Ras signaling via the PI3-kinase pathway which promotes self-renewal, whereas inhibition of ERK blocks differentiation.
