Meiotic Silencing by Unpaired DNA [PDF]
, 2001 The silencing of gene expression by segments of DNA present in excess of the normal number is called cosuppression in plants and quelling in fungi. We describe a related process, meiotic silencing by unpaired DNA (MSUD).

International Journal of Molecular Sciences, 2023 Emerging Mycobacterium tuberculosis (Mtb) resistant strains have continued to limit the efficacies of existing antitubercular therapies. More specifically, mutations in the RNA replicative machinery of Mtb, RNA polymerase (RNAP), have been widely linked to rifampicin (RIF) resistance, which has led to therapeutic failures in many clinical cases ...

Inhibitors of HIV-1 Reverse Transcriptase—Associated Ribonuclease H Activity
Biology, 2012 HIV-1 enzyme reverse transcriptase (RT) is a major target for antiviral drug development, with over half of current FDA-approved therapeutics against HIV infection targeting the DNA polymerase activity of this enzyme. HIV-1 RT is a multifunctional enzyme

eLife, 2022 In plants, selfish genetic elements, including retrotransposons and DNA viruses, are transcriptionally silenced by RNA-directed DNA methylation. Guiding the process are short interfering RNAs (siRNAs) cut by DICER-LIKE 3 (DCL3) from double-stranded ...

Plasmid-based lacZalpha assay for DNA polymerase fidelity: application to archaeal family-B DNA polymerase [PDF]
, 2009 The preparation of a gapped pUC18 derivative, containing the lacZalpha reporter gene in the single-stranded region, is described. Gapping is achieved by flanking the lacZalpha gene with sites for two related nicking endonucleases, enabling the excision ...

Antibodies to the DNA-directed RNA polymerase II subunit RPB1 occur with highest frequency in centenarians [PDF]
Immunity & Ageing, 2016 BACKGROUND: Recently, phage display technology has made it possible to define the circulating repertoire of humoral immunity. This study was designed to define the circulating antibodies specific to centenarians. RESULTS: We used a phage-displayed combinatorial peptide library to screen for peptides (YSATLRY and YSPTLFY) that preferentially react with ...

Chimerization of antibodies by isolation of rearranged genomic variable regions by the polymerase chain reaction [PDF]
, 1991 We describe a new method for amplification, by polymerase chain reaction (PCR), of rearranged segments encoding the variable part of light and heavy chains of an antibody (Ab) from the chromosomal DNA of hybridoma cells for the chimerization ofAbs.

Inhibition of RNA-directed DNA polymerase by aurintricarboxylic acid.
Nucleic Acids Research, 1976 Commercial-grade aurintricarboxylic acid (ATA) inhibits poly(A), poly(C) and viral RNA-directed DNA synthesis by detergent-disrupted virions of Moloney murine leukemia virus. Paper chromatography of crude ATA yields two active components, which appear to

Mode of inhibition of HIV reverse transcriptase by 2-hexaprenylhydroquinone, a novel general inhibitor of RNA-and DNA-directed DNA polymerases [PDF]
Biochemical Journal, 1997 A natural compound from the Red Sea sponge Ircinia sp., 2-hexaprenylhydroquinone (HPH), has been shown to be a general inhibitor of retroviral reverse transcriptases (from HIV-1, HIV-2 and murine leukaemia virus) as well as of cellular DNA polymerases (Escherichia coli DNA polymerase I, and DNA polymerases α and β).

The Inhibitory Action of Kohamaic Acid A Derivatives on Mammalian DNA Polymerase β
Molecules, 2008 We previously isolated a novel natural product, designated kohamaic acid A (KA-A, compound 1), as an inhibitor of the first cleavage of fertilized sea urchin eggs, and found that this compound could selectively inhibit the activities of mammalian DNA ...
