  • Title: Nuclear positioning by actin cables and perinuclear actin: Special and general?
    Author: Huelsmann S, Brown NH.
    Journal: Nucleus; 2014; 5(3):219-23. PubMed ID: 24905988.
    Abstract:
    Nuclear positioning is an important process during development and homeostasis. Depending on the affected tissue, mislocalized nuclei can alter cellular processes such as polarization, differentiation, or migration and lead ultimately to diseases. Many cells actively control the position of their nucleus using their cytoskeleton and motor proteins. We have recently shown that during Drosophila oogenesis, nurse cells employ cytoplasmic actin cables in association with perinuclear actin to position their nucleus. Here, we briefly summarize our work and discuss why nuclear positioning in nurse cells is specialized but the molecular mechanisms are likely to be more generally used.
