  • The eukaryotic cell cycle requires precise temporal coordination of the activities of hundreds of 'executor' proteins (EPs) involved in cell growth and division. (nih.gov)
  • Immunofluorescence staining of CD31+ vessels (red), CD68+ TAMs (green) and DAPI stained cell nuclei (grey) in ER+ BC. (lu.se)
  • Although RNA sequencing is increasingly being used to explore host and pathogen features involved in infection, the team explained, most studies have focused on protein-coding transcripts, assessing bacterial RNA sequences and host RNAs separately. (genomeweb.com)
  • Bacteria and archaea are prokaryotic cells. (sciencedaily.com)
  • The mean cell division time is the average time it takes for one bacteria cell to divide in two (by binary fission). (docbrown.info)
  • During the initial lag phase there is no cell division i.e. no reproduction of the bacteria. (docbrown.info)
  • In this lag phase the bacteria are copying their DNA and synthesising the necessary proteins in order to facilitate the binary fission - this mode of cell division. (docbrown.info)
  • Legionellales bacteria, like the red chains of Legionella pneumophila seen multiplying here inside the protozoan Tetrahymena pyriformis , may have been invading eukaryotic cells for nearly 2 billion years. (the-scientist.com)
  • Lionel Guy, a microbiologist at Uppsala University in Sweden, didn't intend to wade into this debate, he says, when he began profiling an understudied group of bacteria called Legionellales whose members live inside cells and include the bacterium that causes Legionnaire's disease. (the-scientist.com)
  • University of Queensland microbiologist Phil Hugenholtz, who was not involved in the work, says that reconstructing bacterial evolution is notoriously difficult because bacteria don't leave fossils, only chemical traces, and because researchers have documented only a tiny fraction of microbial life.

  • In Aspergillus fumigatus , iron starvation causes extensive transcriptional remodeling involving two central transcription factors, which are interconnected in a negative transcriptional feed-back loop: the GATA-factor SreA and the bZip-factor HapX. (frontiersin.org)
  • Back in 2014, they discovered that ecDNA plays a central role in the drug resistance of certain brain tumors by enabling tumors to rapidly change the amount of oncogenes they contain-and thereby determine whether a cell transforms into a tumor cell. (genengnews.com)
  • There can be several hundred chloroplasts in one cell. (protopage.com)
  • In this study, highly purified, flow-cytometry sorted, classified in relation to normal B-cell differentiation [1]. (lu.se)
  • Host metabolism reprogramming is a key feature of Mycobacterium tuberculosis (Mtb) infection that enables the survival of this pathogen within phagocytic cells and modulates the immune response facilitating the spread of the tuberculosis disease. (bvsalud.org)
  • You will also employ functional assays investigating host-pathogen interactions in vitro, such as serum bactericidal assay or adherence to eukaryotic cells. (lu.se)
