Mechanical properties of the nucleus are remodeled not only by extracellular forces transmitted to the nucleus but also by internal modifications, such as those induced by viral infections. During herpes simplex virus type 1 infection, the viral regulation of essential nuclear functions and growth of the nuclear viral replication compartments are known to reorganize nuclear structures. However, little is known about how this infection-induced nuclear deformation changes nuclear mechanobiology.

Soybeans are a critical crop that provides both protein and oil. In response to environmental stresses, mitogen-activated protein kinases (MPKs) play a key role in transmitting stress signals to the nucleus to initiate stress-responsive actions. Drought stress reduces plant development and productivity but the specific MPK responsible for drought stress responses has not been previously identified.

Dry eye disease (DED) is a common multifactorial disorder characterized by a deficiency in the quality and/or quantity of tear fluid. Tear hyperosmolarity, the dysfunction of ion channel proteins, and eye inflammation are primarily responsible for the development and progression of DED. Alterations in the structure and/or function of ion channel receptors (transient receptor potential ankyrin 1 (TRPA1), transient receptor potential melastatin 8 (TRPM8), transient receptor potential vanilloid 1 and 4 (TRPV1 and TRPV4)), and consequent hyperosmolarity of the tears represent the initial step in the development and progression of DED.

Introduction: Cell fate determination and transition are of paramount importance in biology and medicine. Naive pluripotency could be achieved by reprogramming differentiated cells. However, the mechanism is less clear.

The Mimosa pudica leaf has motor organs allowing movements driven by cell osmotic changes in the parenchyma cells in response to various stimuli. Short white light pulses induce rapid and large seismonastic-like movements (denoted "photostimulation") of the primary pulvini in various leaves within 120 s after the onset of light. An early event recorded is a wavelength-related modification of the plasma membrane difference: potential depolarization under white, blue, green, and red wavelengths, and hyperpolarization under far red wavelengths (and also in darkness).
