A novel class of Mrna-containing cytoplasmic granules are produced in response to UV-irradiation
(American Society for Cell Biology, 2008)
Nucleic acids are substrates for different types of damage, but little is known about the fate of damaged RNAs. We addressed the existence of an RNA-damage response in yeast. The decay kinetics of GAL1p-driven mRNAs revealed ...

A Reanalysis of the Ancient Mitochondrial DNA Sequences Recovered from Neandertal Bones
(Society for Molecular Biology and Evolution, 2002)
Recent reports analyzing mitochondrial DNA sequences from Neandertal bones have claimed that Neandertals and modern humans are different species. The phylogenetic analyses carried out in these articles did not take into ...

Yeast Genetic Analysis Reveals the Involvement of Chromatin Reassembly Factors in Repressing HIV-1 Basal Transcription
(Public Library of Science, 2009)
Rebound of HIV viremia after interruption of anti-retroviral therapy is due to the small population of CD4+ T cells that remain latently infected. HIV-1 transcription is the main process controlling post-integration latency. ...

Identification of a serine hydrolase which cleaves the alicyclic ring of tetralin
(American Society for Microbiology, 2000)
A gene designated thnD, which is required for biodegradation of the organic solvent tetralin by Sphingomonas macrogoltabidus strain TFA, has been identified. Sequence comparison analysis indicated that thnD codes for a ...

Chromosomal translocations caused by either Pol32-dependent or Pol32-independent triparental break-induced replication
(American Society for Microbiology, 2009)
Double-strand breaks (DSBs) are harmful DNA lesions that can generate chromosomal rearrangements or chromosome losses if not properly repaired. Despite their association with a number of genetic diseases and cancer, the ...

Insertion hot spot for horizontally acquired DNA within a bidirectional small-RNA locus in Salmonella enterica
(American Society for Microbiology, 2008)
In Escherichia coli and Salmonella enterica, RyeA and RyeB RNAs are encoded on opposite DNA strands at the same locus. We present evidence indicating that the last 23 bp of the ryeB gene, corresponding to an internal portion ...

An Antifungal Exo-alpha 1,3-Glucanase (AGN13.1) from the Biocontrol Fungus Trichoderma harzianum
(American Society for Microbiology, 2001)
Trichoderma harzianum secretes α-1,3-glucanases when it is grown on polysaccharides, fungal cell walls, or autoclaved mycelium as a carbon source (simulated antagonistic conditions). We have purified and characterized one ...

Human CtIP Mediates Cell Cycle Control of DNA End Resection and Double Strand Break Repair
(American Society for Biochemistry and Molecular Biology, 2009)
In G0 and G1, DNA double strand breaks are repaired by nonhomologous end joining, whereas in S and G2, they are also repaired by homologous recombination. The human CtIP protein controls double strand break (DSB) resection, ...
