Article Synopsis
  • - Transcription occurs in bursts, with gene promoters toggling between active and inactive states, and enhancers play a crucial role by affecting how often, how long, and how intensely these bursts happen in animal development.
  • - Research shows that various enhancers can produce different levels of transcription using similar burst-control techniques, including increasing burst frequency and amplitude while keeping duration steady.
  • - A study comparing transcription patterns in natural and artificial contexts revealed that enhancers maintain consistent bursting strategies, suggesting a shared molecular mechanism influencing these patterns across different regulatory environments.

We report a virus infecting Entomophthora muscae, a behavior-manipulating fungal pathogen of dipterans. The virus, which we name Berkeley Entomophthovirus, is a positive-strand RNA virus in the iflaviridae family of capsid-forming viruses, which are mostly known to infect insects. The viral RNA is expressed at high levels in fungal cells in vitro and during in vivo infections of Drosophila melanogaster, and virus particles can be seen intracellularly in E.

Chemotherapy-induced thrombocytopenia (CIT) is a common challenge of cancer therapy and can lead to chemotherapy dose reduction, delay, and/or discontinuation, affecting relative dose intensity, and possibly adversely impacting cancer care. Besides changing anticancer regimens, standard management of CIT has been limited to platelet transfusions and supportive care. Use of the thrombopoietin receptor agonist romiplostim, already approved for use in immune thrombocytopenia, has shown promising signs of efficacy in CIT.

Long-read sequencing is driving rapid progress in genome assembly across all major groups of life, including species of the family Drosophilidae, a longtime model system for genetics, genomics, and evolution. We previously developed a cost-effective hybrid Oxford Nanopore (ONT) long-read and Illumina short-read sequencing approach and used it to assemble 101 drosophilid genomes from laboratory cultures, greatly increasing the number of genome assemblies for this taxonomic group. The next major challenge is to address the laboratory culture bias in taxon sampling by sequencing genomes of species that cannot easily be reared in the lab.

Article Synopsis
  • Understanding the role of transcription factor binding sites in gene regulation is a critical and complex issue in biology, particularly for multicellular organisms.
  • Massively parallel reporter assays (MPRAs) enable high-throughput measurement of gene expression from numerous regulatory sequences in cell cultures but face limitations in whole organisms due to the need for DNA library integration.
  • Researchers developed a system using base editing technology to introduce targeted mutations in the genomes of cell cultures and whole organisms, significantly improving the ability to study enhancer functions by using multiple guide RNAs for efficient mutagenesis.
