Novikova O, Smith D, Hahn I, Beauregard A, Belfort M
PLoS Genet
. 2014 Dec;
10(12):e1004853.
PMID: 25474706
Mobile genetic elements either encode their own mobilization machineries or hijack them from other mobile elements. Multiple classes of mobile elements often coexist within genomes and it is unclear whether...

Beauregard A, Smith E, Petrone B, Singh N, Karch C, McDonough K, et al.
RNA Biol
. 2013 Jan;
10(3):397-405.
PMID: 23324607
Yersinia pestis, the etiologic agent of plague, is closely related to Yersinia pseudotuberculosis evolutionarily but has a very different mode of infection. The RNA-binding regulatory protein, Hfq, mediates regulation by...

Martin J, Halvorsen M, Davis-Neulander L, Ritz J, Gopinath C, Beauregard A, et al.
RNA
. 2011 Nov;
18(1):77-87.
PMID: 22109839
A majority of SNPs (single nucleotide polymorphisms) map to noncoding and intergenic regions of the genome. Noncoding SNPs are often identified in genome-wide association studies (GWAS) as strongly associated with...

Quarrier S, Martin J, Davis-Neulander L, Beauregard A, Laederach A
RNA
. 2010 Apr;
16(6):1108-17.
PMID: 20413617
Structure mapping experiments (using probes such as dimethyl sulfate [DMS], kethoxal, and T1 and V1 RNases) are used to determine the secondary structures of RNA molecules. The process is iterative,...

Beauregard A, Curcio M, Belfort M
Annu Rev Genet
. 2008 Aug;
42:587-617.
PMID: 18680436
Retrotransposons mobilize via RNA intermediates and usually carry with them the agent of their mobility, reverse transcriptase. Retrotransposons are streamlined, and therefore rely on host factors to proliferate. However, retrotransposons...

Beauregard A, Chalamcharla V, Piazza C, Belfort M, Coros C
Mol Microbiol
. 2006 Sep;
62(3):709-22.
PMID: 17005014
Group II introns are mobile genetic elements that invade their cognate intron-minus alleles via an RNA intermediate, in a process known as retrohoming. They can also retrotranspose to ectopic sites...

Coros C, Landthaler M, Piazza C, Beauregard A, Esposito D, Perutka J, et al.
Mol Microbiol
. 2005 Apr;
56(2):509-24.
PMID: 15813740
Group II introns are mobile retroelements that invade their cognate intron-minus gene in a process known as retrohoming. They can also retrotranspose to ectopic sites at low frequency. Previous studies...

Ichiyanagi K, Beauregard A, Belfort M
Proc Natl Acad Sci U S A
. 2003 Dec;
100(26):15742-7.
PMID: 14673083
Group II introns, widely believed to be the ancestors of nuclear pre-mRNA introns, are catalytic RNAs found in bacteria, archaea, and eukaryotes. They are mobile genetic elements that move via...

Ichiyanagi K, Beauregard A, Lawrence S, Smith D, Cousineau B, Belfort M
Mol Microbiol
. 2002 Nov;
46(5):1259-72.
PMID: 12453213
Catalytic group II introns are mobile retroelements that invade cognate intronless genes via retrohoming, where the introns reverse splice into double-stranded DNA (dsDNA) targets. They can also retrotranspose to ectopic...
