  • During the fourth week of embryologic development, the single cell thick ectoderm and underlying mesoderm begin to proliferate and differentiate. (medscape.com)
  • These gradients are supposed to represent important bioelectrical cues during oogenesis, e.g., by serving as electrochemical prepatterns in modifying cell polarity and cytoskeletal organisation. (biomedcentral.com)
  • LKB1, also known as STK11 , is a master kinase that serves as an energy metabolic sensor and is involved in cell polarity regulation. (biomedcentral.com)
  • Furthermore, LKB1 helps establish and maintain cell polarity in mammals. (biomedcentral.com)
  • Cell division orientation is thought to result from a competition between cell geometry and polarity domains controlling the position of the mitotic spindle during mitosis. (elifesciences.org)
  • Depending on the level of cell shape anisotropy or the strength of the polarity domain, one dominates the other and determines the orientation of the spindle. (elifesciences.org)
  • Here, we show that cell geometry and polarity domains cooperate, rather than compete, in positioning the cleavage plane during UCDs in early ascidian embryos. (elifesciences.org)
  • By systematically varying mitotic cell shape, we could modulate the effect of attractive and repulsive polarity domains and consequently generate predicted daughter cell size asymmetries and position. (elifesciences.org)
  • Yet, whether and how cell geometry and polarity domains compete with each other not only to determine the orientation but also the centering of the mitotic spindle leading to equal or unequal cell divisions (UCDs) remains unclear. (elifesciences.org)
  • Zinc possesses anti‑inflammatory activity by inhibiting NF‑κB signaling and modulation of regulatory T‑cell functions that may limit the cytokine storm in COVID‑19. (spandidos-publications.com)
