DAPK3-Ablation Regulates the AMPK/mTOR-GPX4 Signaling Pathway to Affect Biological Functions of Staphylococcus aureus-Treated Bone Marrow Mesenchymal Stem Cells and Potentially Ameliorate Osteomyelitis.

Staphylococcus aureus (SA)-caused osteomyelitis (OM) is inflammation-related refractory disease that seriously degrades the life quality of human beings. Unfortunately, up until now, the molecular mechanisms of OM progression have not been fully delineated, which hampered the development of treatment strategies for this disease. The present study aimed to resolve this issue and a novel DAPK3/AMPK/mTOR-GPX4 signal pathway was significantly linked to the development of OM.

Efficacy and safety of lateral lumbar interbody fusion for lumbar degenerative diseases with or without auxiliary posterior fixation: a meta-analysis and systematic review.

Background: There is no conclusive evidence from evidence-based medicine that clarifies whether the efficacy and safety of lateral lumbar interbody fusion (LLIF) differ significantly with or without auxiliary posterior fixation. This study embarks on a comprehensive comparative meta-analysis, delving into both domestic and international research landscapes, to scrutinize the efficacy of stand-alone LLIF versus LLIF coupled with auxiliary posterior fixation in the treatment of degenerative lumbar diseases.

Methods: In this meta-analysis, we searched Pubmed, Embase, and Cochrane databases from inception to December 2023.

The Sirt1/FOXO signal pathway involves in regulating osteomyelitis progression via modulating mitochondrial dysfunctions and osteogenic differentiation.

The Sirtuin-1 (Sirt1) gene has been reported to be closely associated with the progression of multiple diseases, but its role in regulating osteomyelitis (OM) pathogenesis has not been explored. The murine long bone-derived osteocyte-like MLO-Y4 cells and osteoblast-like MC3T3-E1 cells were exposed to Staphylococcal protein A (SpA) treatment to establish the in vitro OM models. The expression levels of Osteoblast-specific genes (OCN, OPN and RUNX2), osteoclastic genes (CTSK, MMP9 and ACP5) and the FOXO pathway-related proteins (FOXO1, p-FOXO1, FOXO3 and p-FOXO3) were detected by performing Real-Time qPCR and Western Blot analysis.
