Abstract Liver cell hydration (cell volume) is dynamic and can change within minutes under the influence of hormones, nutrients, and oxidative stress. Such volume changes were identified as a novel and important modulator of cell function. It provides an early example for the interaction between a physical parameter (cell volume) on the one hand and metabolism, transport, and gene expression on the other. Such events involve mechanotransduction (osmosensing) which triggers signaling cascades towards liver function (osmosignaling). This article reviews our own work on this topic with emphasis on the role of β1 integrins as (osmo-)mechanosensors in the liver, but also on their role in bile acid signaling.

Volume Decrease

The purpose of this study was to examine the inability of paraplegic (P) subjects to redistribute fluid below the spinal cord lesion during arm exercise, with emphasis on the role of the sympathetic system in this redistribution failure. Fifteen male P and 15 male able-bodied [control (C)] subjects performed arm cranking exercise, and volume changes in the calf were measured by strain gauge plethysmography before, during, and after exercise. Muscle pump activity in the legs of C subjects was eliminated. The rate of calf volume decrease at the beginning and halfway points of the exercise period, the total volume decrease during exercise, and the volume increase during recovery were significantly lower in P than in C subjects. Whereas completeness of the lesion had no influence on leg volume changes, the rate of calf volume decrease at the beginning of exercise and the total volume decrease during exercise were significantly correlated with the level of the spinal cord lesion. This study confirms that P subjects are unable to redistribute fluid effectively below the spinal cord injury during arm exercise, which is partly caused by a loss of sympathetically induced vasoconstriction and which appears to be independent of the completeness of the lesion but dependent on its level.

We investigate the effect of the increased molecular bulk in the ‘head’ group for a class of newly synthesized azobenzene chromophores and demonstrate that motifs with larger free-volume changes during isomerization drive photoinduced macromolecular phenomena.
