Zingerone treats postmenopausal osteoporosis via increased ferroptosis sensitivity by p53-mediated regulation of Sat1 and Gpx4 expression

ABSTRACT: Zingerone, a component of dried ginger, has known anti-ulcer and bone growth-promoting effects, but its impact on postmenopausal osteoporosis (PO) is unclear. This study investigates the therapeutic potential and underlying mechanisms of zingerone in PO. A concentration-dependent effect identified on osteoclast precursors: at low concentrations, zingerone maintains low ROS levels, enhance proliferation, and facilitates bone remodelling; at high concentrations, it elevates ROS levels, enhances ferroptosis sensitivity, and suppresses osteoclast formation. Zingerone significantly improves bone mass in an ovariectomised mouse model of PO. Metabolomics identifies 869 differential metabolites linked to glutathione and purine metabolism. Transcriptomics highlights pathways including ferroptosis, leukocyte migration, and cell adhesion. In RAW264.7 cells, zingerone modulates p53, enhances ferroptosis sensitivity, increasing ROS and Fe2+, upregulates Sat1, and downregulates Gpx4, suggesting that zingerone may act via p53-mediated ferroptosis, indicating potential clinical utility. Before clinical application, the dose-dependent effects of zingerone on bone remodelling and its underlying mechanisms warrant further investigation.

Project description:The paper describes a model of multiple myeloma. Created by COPASI 4.26 (Build 213) This model is described in the article: A mathematical model of cell equilibrium and joint cell formation in multiple myeloma M.A. Koenders, R. Saso Journal of Theoretical Biology 390 (2016) 73–79 Abstract: In Multiple Myeloma Bone Disease healthy bone remodelling is affected by tumour cells by means of paracrine cytokinetic signalling in such a way that osteoclast formation is enhanced and the growth of osteoblast cells inhibited. The participating cytokines are described in the literature. Osteoclast-induced myeloma cell growth is also reported. Based on existing mathematical models for healthy bone remo- delling a three-way equilibrium model is presented for osteoclasts, osteoblasts and myeloma cell populations to describe the progress of the illness in a scenario in which there is a secular increase in the cytokinetic interactive effectiveness of paracrine processes. The equilibrium state for the system is obtained. The paracrine interactive effectiveness is explored by parameter variation and the stable region in the parameter space is identified. Then recently-discovered joint myeloma–osteoclast cells are added to the model to describe the populations inside lytic lesions. It transpires that their presence expands the available parameter space for stable equilibrium, thus permitting a detrimental, larger population of osteoclasts and myeloma cells. A possible relapse mechanism for the illness is explored by letting joint cells dissociate. The mathematics then permits the evaluation of the evolution of the cell populations as a function of time during relapse.
