  • The overexpression of eIF4E leads to accelerated cell division and malignant transformation. (biosyn.com)
  • Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. (joplink.net)
  • Bacterial cell division is an essential and fundamental process required to sustain life. (uoguelph.ca)
  • Geert Kops, Hubrecht Institute: "An accurate, coordinated division is essential to a cell's success. (uu.nl)
  • The discovery that an essential protein plays a protective role during cell division, could open the door to better targeted treatment of fast-growing cancer cells. (news-medical.net)
  • As a result, we lacked essential information in order to understand the dynamic architecture of the mitotic spindle and how it contributes to cell division," says Lüders. (sciencedaily.com)
  • Satellite cells assure postnatal skeletal muscle growth and repair. (nih.gov)
  • Bacteria dynamically regulate cell size and growth to thrive in changing environments. (nature.com)
  • Here we develop a quantitative theory connecting bacterial growth and division rates to proteome allocation in time-varying nutrient environments. (nature.com)
  • In such environments, cell size and growth are regulated by trade-offs between prioritization of biomass accumulation or division, resulting in decoupling of single-cell growth rate from population growth rate. (nature.com)
  • Specifically, bacteria transiently prioritize biomass accumulation over production of division machinery during nutrient upshifts, while prioritizing division over growth during downshifts. (nature.com)
  • Unbalanced cell growth and impaired cell division occur since nuclear maturation is arrested. (medscape.com)
  • The expression of eIF4E influences cell growth and phenotype. (biosyn.com)
  • Overview of Cancer A cancer is an abnormal growth of cells (usually derived from a single abnormal cell). (msdmanuals.com)
  • Peptidoglycan hydrolases are enzymes that cleave the peptidoglycan of the bacterial cell wall, facilitating cell growth, cell division, and peptidoglycan turnover. (bvsalud.org)
  • There are hundreds of mitochondria in a plant cell and it also converts glucose into energy. (protopage.com)
  • However, this approach neglects the diversity of actin present in different (non-muscle) cell types. (upstate.edu)
  • The problem is, not all cells have this muscle actin. (upstate.edu)
  • We were concerned that everybody is using rabbit muscle actin because we knew that yeast proteins didn't interact with muscle actin well. (upstate.edu)
  • Most of the cells in our body rely on actin to do a whole lot of things," explains Haarer. (upstate.edu)
  • By investigating the precise mechanisms of actin in different cell types, researchers aim to identify potential therapeutic targets and develop interventions to combat these diseases. (upstate.edu)
