Abstract:
Transforming growth factor-beta1 (TGF-beta1), a multi-functional cytokine, is involved in regulating a variety of cellular activities and the serum/plasma TGF-beta1 level is altered with various diseases. However, most published reports have described adult patients, and so we investigated the clinical significance of serum TGF-beta1 level in pediatric patients. The diagnostic application of the measurement of serum TGF-beta1 level depends critically on the control value, however, there is no information on the control value of serum TGF-beta1 for children. In the present study, we determined the serum TGF-beta1 level of healthy Japanese children as a control value with enzyme-linked immunosorbent assay (ELISA). The serum TGF-beta1 level of children (0-14 years old) was significantly higher than that of adults (over 15 years old) (p < 0.01). Thus, it is recommended that when the serum TGF-beta1 levels of patients are evaluated, they should be compared with those of age-matched controls.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
