HACE1 negatively handles neuroinflammation via ubiquitylating along with degrading Rac1 in Parkinson's disease types.

Aromatase inhibitor (AI)-associated bone loss increases the risk of bone fracture and reduces patients' quality of life, making it a critical issue worldwide. We conducted a prospective non-randomized clinical trial (UMIN-CTR, UMIN 000016173) to assess the effect of denosumab on bone loss in patients treated with adjuvant AI and have previously reported the results at 12 and 24months. This study aimed to present the results at 36months of treatment with denosumab for osteopenia in breast cancer patients who were undergoing treatment with adjuvant AI; 36months is the longest denosumab treatment period reported so far.

Patients received 60-mg denosumab subcutaneously every 6months. Daily supplements containing 500-mg elemental calcium and at least 400 international units of vitamin D were highly recommended throughout the study period. The levels of bone mineral density (BMD) and bone turnover markers, serum tartrate-resistant acid phosphatase isoform 5b, and bone alkaline phosphatase were determined at baseline and 6, 12, 18, 24, and 36months.

At 36months, the bone mineral density of the lumbar spine, right femoral neck, and left femoral neck were found to increase by 8.8% (95% confidence interval CI 7.6-10.1), 4.3% (95% CI 3.0-5.5), and 3.1% (95% CI 2.1-4.1), respectively. No non-traumatic clinical fractures occurred in patients receiving AI and denosumab.

Twice-yearly administration of denosumab to the breast cancer patients treated with adjuvant AI, regardless of the skeletal site, resulted in consistent increases in BMD without severe adverse events at 36months.

Osteoblast-lineage cells including osteoblasts and osteocytes express RANKL, which is regulated by several different factors, including hormones, cytokines, and mechanical forces. In vivo and in vitro analyses have demonstrated that various types of mechanosensing proteins on the cell membrane (i.e. mechanosensors) and intracellular mechanosignaling proteins play essential roles in the differentiation and functions of osteoblasts, osteoclasts, and osteocytes via soluble factors, such as sclerostin, Wnt ligands, and RANKL. find more This section provides an overview of the in vivo and in vitro evidence for the regulation of RANKL expression by mechanosensing and mechanotransduction.
The jabuticaba peel extract (JPE) contains bioactive compounds that regulate fat metabolism. Because the negative correlation between fat accumulation and bone formation in bone marrow, we hypothesized that JPE inhibits adipocyte as well as favors osteoblast differentiation of mesenchymal stromal cells (MSCs) under healthy and osteoporotic conditions, a disease that display an imbalance between adipocyte and osteoblast differentiation resulting in reduced bone mass.

To test these hypotheses, bone marrow MSCs were harvested from healthy and osteoporotic ratsand cultured in adipogenic and osteogenic media with three concentrations of JPE, 0.25, 5 and 10µg/ml, and vehicle (control). After selecting the most efficient concentrations of JPE, we used them to evaluate adipocyte and osteoblast differentiation of MSCs from both sources.

We observed that, in general, JPE inhibited adipocyte differentiation of MSCs with more pronounced effects in cells from healthy than osteoporotic rats. In addition, JPE increased osteoblast differentiation, exhibiting a slightly higher osteogenic potential on MSCs from osteoporotic compared to healthy condition.

Our results demonstrated that JPE drives MSCs to inhibit adipocyte differentiation and toward osteoblast differentiation under healthy and osteoporotic conditions. These findings pave the way for further translational studies to investigate the therapeutic possibilities of JPE in both prevention and treatment of osteoporosis.

There is a need for a cost-effective method to identify individuals with a high risk of osteoporosis. This study aimed to investigate the suitability of hand grip strength in predicting the risk of osteoporosis in Asian adults.

In this cross-sectional, hospital-based study of 1007 participants, the bone mineral density of the spine and hips was evaluated using dual-energy X-ray absorptiometry according to the 2019 International Society for Clinical Densitometry official positions. Bone microarchitecture was evaluated using the trabecular bone score, and hand grip strength was measured in the dominant hand using a hand digital dynamometer.

Hand grip strength was significantly related to bone density and bone microarchitecture. Moreover, hand grip strength was a significant predictor of osteoporosis in both women and men. For osteoporosis prediction in women, a threshold of 21.9kg of hand grip strength had a sensitivity of 59%, specificity of 59%, and area under the curve (AUC) of 0.61. In men, a threshold of 28.7kg had a sensitivity of 66%, specificity of 78%, and AUC of 0.75. The optimal cutoff strengths for osteoporosis depended on age and sex.

The measurement of hand grip strength is a simple, cost-effective and an easy assessment method for identifying individuals at ahigh risk ofosteoporosis. The cutoff strength for evaluating osteoporosis in adults is age and sex specific.
