TL;DR: A preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes, is reported here to identify new gene alleles, persistent genotypes, compensatory mutations, and a potential virulence determinant.
Abstract: The spread of H5N1 avian influenza viruses (AIVs) from China to Europe has raised global concern about their potential to infect humans and cause a pandemic. In spite of their substantial threat to human health, remarkably little AIV whole-genome information is available. We report here a preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes. We combine this new information with public AIV data to identify new gene alleles, persistent genotypes, compensatory mutations, and a potential virulence determinant.

TL;DR: This work suggests that autophagic clearance of stress granule related and pathogenic RNP granules that arise in degenerative diseases may be important in reducing their pathology.

TL;DR: It is shown that the numbers (valence) of aromatic residues in PLDs determine the extent of temperature-dependent compaction of individual molecules in dilute solutions, which determines full binodals that quantify concentrations of PLDs within coexisting dilute and dense phases as a function of temperature.
Abstract: Prion-like domains (PLDs) can drive liquid-liquid phase separation (LLPS) in cells. Using an integrative biophysical approach that includes nuclear magnetic resonance spectroscopy, small-angle x-ray scattering, and multiscale simulations, we have uncovered sequence features that determine the overall phase behavior of PLDs. We show that the numbers (valence) of aromatic residues in PLDs determine the extent of temperature-dependent compaction of individual molecules in dilute solutions. The valence of aromatic residues also determines full binodals that quantify concentrations of PLDs within coexisting dilute and dense phases as a function of temperature. We also show that uniform patterning of aromatic residues is a sequence feature that promotes LLPS while inhibiting aggregation. Our findings lead to the development of a numerical stickers-and-spacers model that enables predictions of full binodals of PLDs from their sequences.

TL;DR: A pan-cancer study of somatic alterations, including single nucleotide variants, small insertions or deletions, structural variations, copy number alterations, gene fusions and internal tandem duplications in 1,699 paediatric leukaemias and solid tumours across six histotypes, provides a comprehensive genomic architecture for paediatric cancers.
Abstract: Analysis of molecular aberrations across multiple cancer types, known as pan-cancer analysis, identifies commonalities and differences in key biological processes that are dysregulated in cancer cells from diverse lineages. Pan-cancer analyses have been performed for adult but not paediatric cancers, which commonly occur in developing mesodermic rather than adult epithelial tissues. Here we present a pan-cancer study of somatic alterations, including single nucleotide variants, small insertions or deletions, structural variations, copy number alterations, gene fusions and internal tandem duplications in 1,699 paediatric leukaemias and solid tumours across six histotypes, with whole-genome, whole-exome and transcriptome sequencing data processed under a uniform analytical framework. We report 142 driver genes in paediatric cancers, of which only 45% match those found in adult pan-cancer studies; copy number alterations and structural variants constituted the majority (62%) of events. Eleven genome-wide mutational signatures were identified, including one attributed to ultraviolet-light exposure in eight aneuploid leukaemias. Transcription of the mutant allele was detectable for 34% of protein-coding mutations, and 20% exhibited allele-specific expression. These data provide a comprehensive genomic architecture for paediatric cancers and emphasize the need for paediatric cancer-specific development of precision therapies.

TL;DR: In the study of alternative or additional mechanisms of resistance operating during antiviral therapy, overexpression and amplification of the MRP4 gene correlated with ATP-dependent efflux of PMEA and azidothymidine monophosphate from cells and, thus, with resistance to these drugs.
Abstract: Dideoxynucleosides, which are potent inhibitors of HIV reverse transcriptase and other viral DNA polymerases, are a common component of highly active anti-retroviral therapy (HAART) (ref. 1). Six reverse transcriptase inhibitors have been approved for human use: azidothymidine; 2'3'-dideoxycytidine; 2'3'-dideoxyinosine; 2',3'-didehydro-3'deoxythymidine; 2',3'-dideoxy-3'-thiacytidine; and 4-[2-amino-6-(cyclopropylamino) -9H-purin-9-yl]-2-cyclopentene-1-methanol. Although drug-resistant HIV strains resulting from genetic mutation have emerged in patients treated with HAART (ref. 1), some patients show signs of drug resistance in the absence of drug-resistant viruses2,3. In our study of alternative or additional mechanisms of resistance operating during antiviral therapy, overexpression and amplification of the MRP4 gene correlated with ATP-dependent efflux of PMEA (9-(2-phosphonylmethoxyethyl)adenine) and azidothymidine monophosphate from cells and, thus, with resistance to these drugs. Overexpression of MRP4 mRNA and MRP4 protein severely impaired the antiviral efficacy of PMEA, azidothymidine and other nucleoside analogs. Increased resistance to PMEA and amplification of the MRP4 gene correlated with enhanced drug efflux; transfer of chromosome 13 containing the amplified MRP4 gene conferred resistance to PMEA. MRP4 is the first transporter, to our knowledge, directly linked to the efflux of nucleoside monophosphate analogs from mammalian cells.
