Recombination in Wolbachia [PDF]

open access: yesCurrent Biology, 2001
Wolbachia are widely distributed intracellular bacteria that cause a number of reproductive alterations in their eukaryotic hosts. Such alterations include the induction of parthenogenesis, feminization, cytoplasmic incompatibility, and male killing [1-11].

Unwinding to Recombine [PDF]

open access: yesMolecular Cell, 2012
The MCM proteins are best known for their role in DNA replication, MCM2-7 forming the replicative helicase. Now, two reports in this issue of Molecular Cell, Nishimura et al. (2012) and Lutzmann et al. (2012) show the less well understood MCM8 and MCM9 to be crucial for effective homologous recombination.

Mechanism of substrate hydrolysis by the human nucleotide pool sanitiser DNPH1

open access: yesNature Communications, 2023
Poly(ADP-ribose) polymerase (PARP) inhibitors are used in the clinic to treat BRCA-deficient breast, ovarian and prostate cancers. As their efficacy is potentiated by loss of the nucleotide salvage factor DNPH1 there is considerable interest in the ...

Reproductive Isolation Between Taxonomically Controversial Forms of the Gray Voles (Microtus, Rodentia; Arvicolinae): Cytological Mechanisms and Taxonomical Implications

open access: yesFrontiers in Genetics, 2021
The formation of hybrid sterility is an important stage of speciation. The voles of the genus Microtus, which is the most speciose genus of rodents, provide a good model for studying the cytological mechanisms of hybrid sterility.

Wolbachia and recombination [PDF]

open access: yesTrends in Genetics, 2001
The endocellular bacterium Wolbachia manipulates its hosts’ reproduction in an impressive variety of ways: it can induce male killing, feminization, thelytokous parthenogenesis and cytoplasmic incompatibility (CI; embryonic mortality resulting from crosses between Wolbachia-infected males and uninfected females).

SARS-CoV-2: from its discovery to genome structure, transcription, and replication

open access: yesCell & Bioscience, 2021
SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

Two Targets, One Hit: new Anticancer Therapeutics to Prevent Tumorigenesis Without Cardiotoxicity

open access: yesFrontiers in Pharmacology, 2021
A serious adverse effect of cancer therapies is cardiovascular toxicity, which significantly limits the widespread use of antineoplastic agents. The promising new field of cardio-oncology offers the identification of potent anti-cancer therapeutics that ...

Quasispecies and recombination

open access: yesTheoretical Population Biology, 2006
Recombination is introduced into Eigen's theory of quasispecies evolution. Comparing numerical simulations of the rate equations in the non-recombining and recombining cases show that recombination has a strong effect on the error threshold and, for a wide range of mutation rates, gives rise to two stable fixed points in the dynamics. This bi-stability

Histone H3 Lysine 56 Acetylation Is Required for Formation of Normal Levels of Meiotic DNA Breaks in S. cerevisiae

open access: yesFrontiers in Cell and Developmental Biology, 2020
Meiotic recombination is initiated by Spo11-catalyzed DNA double-strand breaks (DSBs) that are promoted by histone modifications and histone modifying enzymes. Herein we investigated the role of histone H3 lysine 56 acetylation (H3K56ac) located near the

Recombination in RNA

open access: yesCell, 1982
The aphthovirus genome consists of a single molecule of single-stranded RNA that encodes all the virus-induced proteins. We isolated recombinant aphthoviruses from cells simultaneously infected with temperature-sensitive mutants of two different subtype strains.
