Purpose: As a novel hepatokine, fetuin B involves in various functions of energy metabolism. Recent advance reveals a complex interaction between bone and liver via the secretion of hepatokines. The association between serum fetuin B and osteoporosis was evaluated in a 4-year hospital-based prospective study of 1,370 Chinese postmenopausal women. Methods: Bone mineral densities (BMDs) were obtained on femoral neck and lumbar spines by dual energy X-ray absorptiometry. Serum fetuin B level was tested by enzyme-linked immunosorbent assay. Results: Of the 1,370 participants in the baseline study (2012), 650 subjects were included in the 4-year follow-up study (2016). Serum fetuin B level presented higher in subjects with osteoporosis (106.7 ± 17.6 μg/ml) than it in controls (86.3 ± 17.5 μg/ml) (P < 0.001). Meanwhile, fetuin B positively correlated with triglycerides (r = 0.227, P = 0.001), femoral BMD (r = -0.426, P < 0.001) and lumbar BMD (r = -0.332, P < 0.001). At the 4-year follow-up, 116 subjects had developed osteoporosis. Serum fetuin B concentration was significantly higher in subjects who developed (P < 0.001). The osteoporosis incidence increased from Q1 9.9%, Q2 14.7%, and Q3 17.8% to Q4 30.2% (P for trend < 0.001), among the quartiles of baseline fetuin B. A higher fetuin B baseline level was linked to the incidence of osteoporosis (adjusted OR = 1.179, 95% CI [1.119 – 1.243], P = 0.009). Conclusion: Serum fetuin B levels increased with the development of osteoporosis.

In the past most studies of the control of energy metabolism focus on the role of the phosphorylation potential ATP/ADP.Pi on the regulation of respiration. Studies using NMR techniques have demonstrated that the concentrations of these compounds for oxidation phosphorylation do not change appreciably throughout the cardiac cycle and during increases in cardiac work. Hence regulation of energy production by calcium ions, present in the mitochondrial matrix, has been the object of a number of recent studies.Three exclusively intramitochondnal dehydrogenases are key enzymes for the regulation of oxidative metabolism. They are activated by calcium ions in the low micromolar range. Since, however, earlier estimates of the intramitochondnal calcium, based on equilibrium thermodynamic considerations, were in the millimolar range, a physiological correlation was not evident. The introduction of calcium-sensitive probes fura-2 and indo-1 made monitoring of free calcium during changing energy metabolism possible. These studies were performed on isolated mitochondria and extrapolation to the in vivo situation is more or less speculative.
