Ginger DNA transposons in eukaryotes and their evolutionary relationships with long terminal repeat retrotransposons

Mobile DNA, 2010
Background In eukaryotes, long terminal repeat (LTR) retrotransposons such as Copia, BEL and Gypsy integrate their DNA copies into the host genome using a particular type of DDE transposase called integrase (INT).

Substrate specificity of Ty1 integrase [PDF]

Journal of Virology, 1995
Integration of the Saccharomyces cerevisiae retrotransposon Ty1 requires the element-encoded integrase (IN) protein, which is a component of cytoplasmic virus-like particles (VLPs). Using purified recombinant Ty1 IN and an oligonucleotide integration assay based on Ty1 long terminal repeat sequences, we have compared IN activity on substrates having ...

Systemic Treatments for Recurrent or Metastatic Sinonasal Carcinomas: A Retrospective Multicenter Study

Head &Neck, EarlyView.
ABSTRACT Introduction Sinonasal cancers are rare and heterogeneous and pose a therapeutic challenge at an advanced stage due to the lack of data on appropriate systemic management. Methods This retrospective multicenter study analyzed 83 patients with recurrent or metastatic sinonasal carcinomas ineligible for curative treatment, treated in France ...

Role of pathogenicity island-associated integrases in the genome plasticity of uropathogenic Escherichia coli strain 536

, 2006
(T)he genome of uropathogenic Escherichia coli isolate 536 contains five well-characterized pathogenicity islands (PAIs) encoding key virulence factors of this strain. Except PAI IV536, the four other PAIs of strain 536 are flanked by direct repeats (DRs)

Prevalence of SOS-mediated control of integron integrase expression as an adaptive trait of chromosomal and mobile integrons

Mobile DNA, 2011
Background Integrons are found in hundreds of environmental bacterial species, but are mainly known as the agents responsible for the capture and spread of antibiotic-resistance determinants between Gram-negative pathogens.

Association Between HIV Infection Duration and Left Ventricular Concentric Remodeling and Myocardial Fibrosis: A Cross‐Sectional Study Using Cardiac MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Antiretroviral therapy has transformed HIV into a chronic condition, yet cardiac injury remains a major issue. Purpose To assess the ability of cardiac MR imaging markers to predict cardiac injury and disease progression in HIV‐infected individuals. Study Type Prospective.

Casposase structure and the mechanistic link between DNA transposition and spacer acquisition by CRISPR-Cas

eLife, 2020
Key to CRISPR-Cas adaptive immunity is maintaining an ongoing record of invading nucleic acids, a process carried out by the Cas1-Cas2 complex that integrates short segments of foreign genetic material (spacers) into the CRISPR locus.

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

Insect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Primary and promiscuous functions coexist during evolutionary innovation through whole protein domain acquisitions

eLife, 2020
Molecular examples of evolutionary innovation are scarce and generally involve point mutations. Innovation can occur through larger rearrangements, but here experimental data is extremely limited.

The large plasmid carried class 1 integrons mediated multidrug resistance of foodborne Salmonella Indiana

Frontiers in Microbiology, 2022
Salmonella enterica serovar Indiana (S. Indiana) has aroused widespread concern as an important zoonotic pathogen. The molecular mechanism of multidrug resistance (MDR) in S. Indiana is not known and should be assessed.
