The Mre11-Rad50-Nbs1 (MRN) complex acts as a DNA damage sensor, maintains genome stability during DNA replication, and activates and recruits ataxia-telangiectasia mutated (ATM) to damaged DNA. The genes that encode the MRN proteins are all essential for cell viability, so functional studies of MRN cannot involve deletion of these genes. Mirin is an inhibitor of MRN, inhibiting MRN-dependent phosphorylation of histone H2AX (IC50 = 66 μM).{16934} Through its effects on MRN, mirin prevents activation of ATM. Inhibition of MRN centers on the ability of mirin to block the nuclease activity of Mre11, rather than altering DNA-binding or MRN complex formation. In cells, mirin induces G2 arrest, abolishes the radiation-induced G2/M checkpoint, and prevents homology-directed repair of DNA damage.{16934}

  • 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}
