Summary: Deficiency in COPI complex I may lead to aberrant activation of the STING pathway and inflammatory diseases, with cGAS possibly being the upstream immune sensor driving this process. Targeted inhibition of the cGAS/STING pathway can alleviate inflammation in diseases such as COPA syndrome.

Summary: The cGAS-STING signaling pathway detects dsDNA to trigger innate immune responses and has emerged as a critical mediator of inflammation. Activating the STING/IFN-beta pathway reduces bone resorption, while activation of STING/NF-kappa B increases bone resorption and decreases bone formation, leading to osteoporosis.

Summary: The study investigated the effects of hydrogen peroxide on mitochondrial DNA integrity. The results showed that hydrogen peroxide treatment resulted in DNA breaks, which were then repaired through rapid repair of single-strand breaks and degradation of double-strand breaks-generated linear fragments. Inactivation of mitochondrial DNA degradation resulted in the persistence of linear fragments in mutant cells without affecting the repair of single-strand breaks. These findings highlight the interplay between DNA repair and degradation processes, and the potential generation of somatic mitochondrial DNA deletions.

Summary: The study reveals that UNC13D, associated with familial hemophagocytic lymphohistiocytosis (FHL3), acts as a negative regulator of STING-mediated innate immune response. UNC13D inhibits STING oligomerization and promotes the production of interferon-beta (IFN-beta) induced by DNA viruses. UNC13D deficiency also leads to increased basal level of proinflammatory cytokines.

Summary: This study reveals that Coxsackievirus B3 infection of cardiac myocytes leads to the release of mitochondrial DNA (mtDNA), triggering cardiac macrophage inflammation through the STING dependent mechanism. The mtDNA released by infected cells plays a crucial role in inducing macrophage inflammatory response. Additionally, myocardial mtDNA is identified as a central element driving cardiac inflammation in Coxsackievirus B3-induced viral myocarditis, and STING is considered a promising therapeutic target for protection against RNA viral infections.

Summary: This study shows that deletion of Lats2 gene can protect against acute myocardial infarction (AMI) by reducing cardiac injury and preserving cardiac structure and function. This protective effect may be attributed to the inhibition of mitochondrial fission, release of mtDNA, and activation of the STING/p65 pathway.

Summary: This study found that IQGAP1 induces endothelial cell pyroptosis by regulating mitochondrial function and activating the DNA sensor cGAS-STING. The results showed that IQGAP1 promotes oxidative stress and mtDNA release, activates the cGAS-STING signaling pathway, and leads to NLRP3-mediated pyroptosis. This study expands the understanding of the mechanisms underlying atherosclerosis and identifies new pharmacological targets for treatment.

Summary: This study identified the role of mtDNA as an inflammatory driver in odontoblasts, which defended against bacterial invasion through the cGAS-STING pathway. The findings suggest that targeting the mtDNA-cGAS-STING axis could be a potential therapeutic strategy for preventing severe bacterial inflammation in pulpitis.

Summary: This study demonstrated that mtDNA promotes immunoparalysis of DCs and contributes to sepsis-associated immunosuppression by activating STING signaling. Our findings suggest that mtDNA mediates immunoparalysis of DCs in sepsis, providing new insights into the molecular pathogenesis of immunosuppressive DCs in sepsis.

Summary: Mitochondrial dysfunction is a key aspect of aging, and mitochondrial genome instability can lead to dysfunction and accelerated aging. Recent evidence suggests that environmental stressors like pollutants and pharmaceuticals can contribute to increased mtDNA mutations, potentially impacting aging and disease. More research is needed to understand the effects of chemical exposures on mtDNA mutations and instability, especially in the context of aging, as they may serve as sensitive biomarkers for exposure.

Summary: Vitamin D is crucial for calcium and bone metabolism, with its insufficiency affecting skeletal mineralization and bone growth rate in children. Short-stature children have lower vitamin D levels compared to healthy subjects. Ratios of C3-epi/25(OH)D3 and 25(OH)D2/25(OH)D3 may serve as alternative markers for evaluating vitamin D metabolism/storage in short-stature children.

Summary: This study used a metabolomics approach to analyze the metabolic response of NSCLC patients to EGFR-TKIs or PD-1/PD-L1 inhibitors. The results showed that these treatments induce changes in carnitine, amino acids, fatty acids, and lipids, and alter associated metabolic pathways. These findings provide new clues for understanding the antitumor mechanisms of these treatments from a metabolic perspective.
