Interaction Information:

Comment In tryptophan (TRP)-free diet-treated rats, mean body weight was significantly reduced compared with baseline and with control-diet-treated rats starting from 35 days. TRP-supplement diet resulted in an increase in body weight which did not reach statistical significance as compared with TRP-free diet-treated rats.

Comment Tryptophan (TRP)-free diet significantly reduced the 24-h urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA) compared with control-diet-treated rats at both times of testing. TRP-supplemented diet resulted in a significant increase of 5-HIAA.

Comment Tryptophan (TRP)-free diet significantly worsened bone loss consequent to decreased physical activity at all the skeletal sites examined.

Comment Since mechanical stimulation activates in osteoblasts the Wnt/beta-catenin pathway, the effects of serotonin (5-HT) on various elements of Wnt/beta-catenin pathway were examined. Beta-catenin protein was significantly increased 30 min after 5-HT exposure. 5-HT induced a significant increase in GSK-3beta phosphorylation compared to total GSK3-beta, indicating that 5-HT modulates beta-catenin protein levels by inhibiting GSK-3beta activation.
