Conversion of mechanical force into biochemical signaling.
Physical forces play important roles in regulating cell proliferation, differentiation, and death by activating intracellular signal transduction pathways. How cells sense mechanical stimulation, however, is largely unknown. Most studies focus on cellular membrane proteins such as ion channels, integrins, and receptors for growth factors as mechanosensory units. Here we show that mechanical str...
متن کاملConversion of Mechanical Force into TGF-β-Mediated Biochemical Signals
Mechanical forces influence homeostasis in virtually every tissue [1, 2]. Tendon, constantly exposed to variable mechanical force, is an excellent model in which to study the conversion of mechanical stimuli into a biochemical response [3-5]. Here we show in a mouse model of acute tendon injury and in vitro that physical forces regulate the release of active transforming growth factor (TGF)-β f...
متن کاملBiochemical Studies on Shock
During and following the production of shock by hemorrhage in the normal, suprareno-demedullated, and suprarenalectomized rat, the following significant changes in amino acid and carbohydrate metabolism have been observed. 1. In the intact, suprareno-demedullated, and suprarenalectomized rat there is a progressive rise in the whole blood and plasma amino acid nitrogen levels during and after a ...
متن کاملBiochemical Studies on Inositol
In a previous publication (1, Paper V of this series) the purification and properties of the inositol-cleaving enzyme were described. It was shown that a highly purified enzyme was obtained from rat kidneys which cleaved inositol to D-ghCUI’OniC acid. The purified enzyme was shown to possess SH groups and 1 gram atom of iron per mole of enzyme. Both the SH groups and the iron are necessary for ...
متن کاملBiochemical Studies on Plant Adp - Glucose Pyrophosphorylase Regulatory Properties
By Dongwook Kim, Ph.D. Washington State University December 2007 Chair: Dr. Thomas W. Okita ADP-glucose pyrophosphorylase (AGPase) catalyzes the first committed step of starch synthesis in plants. Plant AGPases are composed of two distinct subunits, a catalytic small subunit (SS) and a non-catalytic large subunit (LS). Previously, we have identified and characterized an allosteric LSP52L mutant...
