We conclude that osteocytogenesis is accompanied by changes in gene expression that may be driven by both genetic and epigenetic components. These changes are likely responsible for the osteocyte phenotype and may contribute to reduced sensitivity to 1,25(OH)(2)D(3).

These findings demonstrate that genetic alterations in osteoblasts can induce acute myeloid leukaemia, identify molecular signals leading to this transformation and suggest a potential novel pharmacotherapeutic approach to acute myeloid leukaemia.

In conclusion, our study does not support the hypothesis that calcium supplementation increases either carotid artery intimal medial thickness or carotid atherosclerosis.

In addition, calcium supplementation and high total calcium intake may indeed reduce carotid atherosclerosis.

Together, these results underscore the involvement of bone, among other tissues, in the disruption of whole-body glucose homeostasis resulting from a HFD and the involvement of insulin and osteocalcin cross-talk in glucose intolerance. Furthermore, our data indicate that insulin resistance develops in bone as the result of lipotoxicity-associated loss of insulin receptors.

The trabecular bone score (TBS) is a gray‐level textural metric that can be extracted from the two‐dimensional lumbar spine dual‐energy X‐ray absorptiometry (DXA) image.

TBS is related to bone microarchitecture and provides skeletal information that is not captured from the standard bone mineral density (BMD) measurement.

Based on these data, lumbar spine TBS holds promise as an emerging technology that could well become a valuable clinical tool in the diagnosis of osteoporosis and in fracture risk assessment.

In conclusion, despite the huge impact of osteoporosis worldwide, our knowledge of bone genetics and biology remains remarkably incomplete.

Our findings and models provide compelling genetic evidence of a novel molecular network regulating adult skeletal homeostasis in vivo, which may help identify new specific therapeutic targets against involution- al, inflammatory, or cancer‐induced bone wasting.

They conclude that Cnr2 deficiency affects expression of a large number of genes in different strains of mice, and that these differences are likely to be responsible in part for the differences in skeletal phenotype that they and others have observed in mice with defective cannabinoid receptor signalling in different genetic backgrounds.

Conclusions This study supports other international studies by showing changes in the incidence of hip fractures after age population adjustment, which denotes a decrease in the younger age groups and among women and shows an increase in both groups over 85 years. The increase in the crude incidence rate of hip fracture in Spain reflects changes in population structure.

The results of this nested case–control study in the CPRD indicate no evidence for a higher risk of MI or cardiovascular death associated with the use of strontium ranelate

in women treated for osteoporosis compared with non-use of this agent in routine medical practice in the UK.
