Identification and Characterization of a Novel Androgen Response Element Composed of a Direct Repeat [PDF]

open access: hybridJournal of Biological Chemistry, 1997
Transcriptional regulation by the androgen receptor (AR) requires its binding to hormone response element nucleotide sequences in DNA. A consensus glucocorticoid response element (GRE) can mediate transactivation by AR and other members of the AR ...

Recombineering in Streptococcus mutans Using Direct Repeat-Mediated Cloning-Independent Markerless Mutagenesis (DR-CIMM) [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Studies of the dental caries pathogen Streptococcus mutans have benefitted tremendously from its sophisticated genetic system. As part of our own efforts to further improve upon the S. mutans genetic toolbox, we previously reported the development of the

Sequence Analysis of the Direct Repeat Region in Mycobacterium bovis [PDF]

open access: greenJournal of Clinical Microbiology, 2001
ABSTRACT Spoligotyping is a major tool for molecular typing of Mycobacterium bovis . This technique is based on the polymorphism of spacers that separate direct repeats (DRs) in the M. tuberculosis complex DR region. Numerous M.

A direct repeat sequence at the Rasgrf1 locus and imprinted expression.

open access: yesGenomics, 1999
Genomic imprinting is an epigenetic modification that can lead to parental-specific monoallelic expression of specific autosomal genes. While methylation of CpG dinucleotides is thought to be a strong candidate for this epigenetic modification, little is

Evidence that direct inhibition of transcription factor binding is the prevailing mode of gene and repeat repression by DNA methylation

open access: yesNature Genetics, 2022
Cytosine methylation efficiently silences CpG-rich regulatory regions of genes and repeats in mammalian genomes. To what extent this entails direct inhibition of transcription factor (TF) binding versus indirect inhibition via recruitment of methyl-CpG ...

Direct observation of repeated infections with endemic coronaviruses [PDF]

open access: yesThe Journal of Infectious Diseases, 2020
AbstractBackgroundWhile the mechanisms of adaptive immunity to pandemic coronavirus SARS-CoV-2 are still unknown, the immune response to the widespread endemic coronaviruses HKU1, 229E, NL63 and OC43 provide a useful reference for understanding repeat infection risk.MethodsHere we used data from proactive sampling carried out in New York City from fall
