Abstract: Background: Active vitamin D analog eldecalcitol is clinically applied in treatment of postmenopausal osteoporosis. This study aims to determine the role of eldecalcitol in the protection of osteocytes from senescence and the associated ferroptosis. Methods: The MLO-Y4 osteocytes were exposed to D-gal inducing senescence. The ovariectomized (OVX) mice treated with D-gal using as an aging inducer were intraperitoneally injected with eldecalcitol. The multiplexed confocal imaging, fluorescence in situ hybridization and transmission electron microscopy were applied in assessing osteocytic properties. Immunochemical staining and immunoblotting were carried out to detect abundance and expression of molecules. Results: The ablation of vitamin D receptor led to a reduction in amounts of osteocytes, a loss of dendrites, an increase in mRNA expression of SASP factors and in protein expression of senescent factors, as well as changes in mRNA expression of ferroptosis-related genes (PTGS2 & RGS4). Eldecalcitol reversed senescent phenotypes of MLO-Y4 cells shown by improving cell morphology and density, decreasing β-gal-positive cell accumulation, and down-regulating protein expression (P16, P21 & P53). Eldecalcitol reduced intracellular ROS and MDA productions, elevated JC-1 aggregates, and up-regulated expression of Nrf2 and GPX4. Eldecalcitol exhibited osteopreserve effects in D-gal-induced aging OVX mice. The confocal imaging displayed its improvement on osteocytic network organization. Eldecalcitol decreased the numbers of senescent osteocytes at tibial diaphysis by SADS assay and attenuated mRNA expression of SASP factors as well as down-regulated protein expression of senescence-related factors and restored levels of ferroptotic biomarkers in osteocytes-enriched bone fraction. It reduced 4-HNE staining area, stimulated Nrf2-positive staining, and promoted nuclear translocation of Nrf2 in osteocytes of mice as well as inhibited and promoted protein expression of 4-HNE and Nrf2, respectively, in osteocytes-enriched bone fraction. Conclusions: The present study revealed the ameliorative effects of eldecalcitol on senescence and the associated ferroptosis of osteocytes, contributing to its preservation against osteoporosis of D-gal-induced senescent ovariectomized mice.

With recombinant alpha-galactosidase AgaAHJG4 from Streptomyces; In aq. phosphate buffer; at 37.0℃; for 24.0h;Catalytic behavior; General procedure: Transglycosylation reactions were carried out using pNPG as the donor at 40mM with various acceptors at 400mM including Xyl, Glc, Gal, Sor, Fru, Man, Lac, Suc, Raf, Sta, Mant, Sort, methanol (MeOH), ethanol (EtOH), ethylene glycol (EgOH), 2-propanol (PrOH), n-butanol (BuOH), 3-methyl-1-butanol (mBuOH), and glycerol (GlOH). Donor and acceptors were preincubated for 10min at 37C. The mixtures were incubated at 37C for 24h after the addition of 0.2UmL-1 rAgaAJB07 or rAgaAHJG4. Reactions were stopped by rapid freezing. Transglycosylation products were analyzed by thin layer chromatography (TLC) using the method of Shivam and Mishra (2010) with some modifications as follows:
