ATF3 Regulates Osteogenic Function by Mediating Osteoblast Ferroptosis in Type 2 Diabetic Osteoporosis
CONCLUSION: Osteoblast ferroptosis under HG conditions is induced by ATF3-mediated inhibition of system Xc- activity, and these events contribute to T2DOP pathogenesis.PMID:36340581 | PMC:PMC9629949 | DOI:10.1155/2022/9872243

Positive programming of the GC-IGF1 axis mediates adult osteoporosis susceptibility in male offspring rats induced by prenatal dexamethasone exposure
In conclusion, PDE-induced intrauterine hypoglucocorticoid exposure could positively program IGF1 expression in bone tissue through the GRα/miR-130a-5p/HDAC4 pathways, thus mediating osteogenic dysdifferentiation and adult osteoporosis susceptibility in male offspring rats.PMID:36174767 | DOI:10.1016/j.bcp.2022.115264

A novel BMP2 secretagogue ameliorates glucocorticoid induced oxidative stress in osteoblasts by activating NRF2 dependent survival while promoting Wnt/ β-catenin mediated osteogenesis
Free Radic Biol Med. 2022 Aug 10:S0891-5849(22)00514-7. doi: 10.1016/j.freeradbiomed.2022.08.007. Online ahead of print.ABSTRACTIn our previous study, a novel BMP2 secretagogue was synthesized belonging to a class of galloyl conjugates of flavanones, with remarkable osteogenic potential that promoted bone regeneration. We aimed to establish the protective effect of our compound against bone loss that co-exists with excess Glucocorticoid (GC) therapy. GC therapy induces osteoblast damage leading to apoptosis by increasing reactive oxygen species (ROS). Our results delineate that compound 5e (a BMP2 secretagogue) activates N...

Downregulation of DNA methyltransferase-3a ameliorates the osteogenic differentiation ability of adipose-derived stem cells in diabetic osteoporosis via Wnt/ β-catenin signaling pathway
CONCLUSIONS: Dnmt3a silencing rescues the negative effects of DOP on ASCs and provides a possible approach for bone tissue regeneration in patients with diabetic osteoporosis.PMID:35927735 | DOI:10.1186/s13287-022-03088-4

MiR-1224-5p modulates osteogenesis by coordinating osteoblast/osteoclast differentiation via the Rap1 signaling target ADCY2
Exp Mol Med. 2022 Jul 13. doi: 10.1038/s12276-022-00799-9. Online ahead of print.ABSTRACTMicroRNAs (miRNAs) broadly regulate normal biological functions of bone and the progression of fracture healing and osteoporosis. Recently, it has been reported that miR-1224-5p in fracture plasma is a potential therapy for osteogenesis. To investigate the roles of miR-1224-5p and the Rap1 signaling pathway in fracture healing and osteoporosis development and progression, we used BMMs, BMSCs, and skull osteoblast precursor cells for in vitro osteogenesis and osteoclastogenesis studies. Osteoblastogenesis and osteoclastogenesis were det...

Notch/NICD/RBP-J signaling axis regulates M1 polarization of macrophages mediated by advanced glycation end products
AbstractAdvanced glycation end products (AGEs) aggregation and macrophages polarization are identified as the main factors contributing to bone diseases caused by aging or diabetes, such as senile or diabetic osteoporosis. Here, we aimed to elucidate the involvement and potential mechanism of AGEs in macrophages polarization and osteoclastogenesis. Firstly, AGEs-treated RAW264.7 macrophages were observed to up-regulate the release of nitric oxide (NO), the expression of M1-associated genes and the surface antigen marker CD86. The detection of osteoclast-related markers and TRAP staining revealed that the osteoclastogenic a...

RNA interference-based osteoanabolic therapy for osteoporosis by a bone-formation surface targeting delivery system
In this study, we identified casein kinase-2 interacting protein-1 encoding gene (Ckip-1), a negative regulator of bone formation, as an effective target of small interfering RNAs (siRNAs) for improving bone mass. Moreover, an impressive (DSS)6-Liposome (Lipos) nanoparticle system that could target the bone formation surface was synthesized to enhance the delivery of Ckip-1 siRNA to osteogenic lineage cells. The in vitro results confirmed that the (DSS)6-Lipos system could efficaciously improve the intracellular delivery of Ckip-1 siRNA without obvious cell toxicity. The in vivo application of the delivery system showed sp...

ROS-induced PADI2 downregulation accelerates cellular senescence via the stimulation of SASP production and NF κB activation
Cell Mol Life Sci. 2022 Feb 26;79(3):155. doi: 10.1007/s00018-022-04186-5.ABSTRACTCellular senescence is closely related to tissue aging including bone. Bone homeostasis is maintained by the tight balance between bone-forming osteoblasts and bone-resorbing osteoclasts, but it undergoes deregulation with age, causing age-associated osteoporosis, a main cause of which is osteoblast dysfunction. Oxidative stress caused by the accumulation of reactive oxygen species (ROS) in bone tissues with aging can accelerate osteoblast senescence and dysfunction. However, the regulatory mechanism that controls the ROS-induced senescence o...
