Stress granule (SG) assembly represents a conserved eukaryotic defense strategy against various insults. Although essential for the ability to cope with deleterious conditions, the signaling pathways controlling SG formation are not fully understood. The energy sensor AMP-activated protein kinase (AMPK) is critical for the cellular stress response. Human(More)
BACKGROUND Importin-α1 belongs to a subfamily of nuclear transport adaptors and participates in diverse cellular functions. Best understood for its role in protein transport, importin-α1 also contributes to other biological processes. For instance, arsenite treatment causes importin-α1 to associate with cytoplasmic stress granules (SGs) in mammalian cells.(More)
BACKGROUND Persistently active PKMζ has been implicated in maintaining spinal nociceptive sensitization that underlies pain hypersensitivity. However, evidence for PKMζ in the maintenance of pain hypersensitivity comes exclusively from short-term studies in males using pharmacological agents of questionable selectivity. The present study examines the(More)
which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract Cancer cells can take up gold nanoparticles of different morphologies. These particles interact with the plasma membrane and often travel to intracellular organelles. Among organelles, the nucleus is especially susceptible to(More)
Background. Chaperones and their co-factors are components of a cellular network; they collaborate to maintain proteostasis under normal and harmful conditions. In particular, hsp70 family members and their co-chaperones are essential to repair damaged proteins. Co-chaperones are present in different subcellular compartments, where they modulate chaperone(More)
