In this study, we aimed to analyze bone fractures and bone mineral densities (BMDs) across patients receiving antidiabetic treatments, considering both overall and specific sites. We comprehensively searched PubMed, Embase, and ClinicalTrials.gov up to March 2024 to determine the effect of antidiabetic agent use on bone health in patients with type 2 diabetes mellitus. The primary outcome was to reveal variations in fractures across different anti-diabetic treatment modalities. The secondary outcome was the differences in BMDs based on treatment type. The fractures were grouped based on the division of specific sites. We also performed a subgroup analysis to identify differences between treatment types by dividing the study by treatment duration. The protocol is registered (CRD42024538789). A total of 234,759 individuals were enrolled in the 242 studies. We observed a trend wherein all anti-diabetic treatments were associated with decreased risk of fracture compared with placebo; however, this was not significant in direct analysis (OR 0.92, 95% CI 0.84-1.01, I² = 0, P = 0.07). For indirect analysis, glucagon-like peptide-1 receptor agonists (GLP1RAs) demonstrated a significant effect on preventing fractures in non-vertebral fracture, hip fracture, vertebral and hip fracture, and overall fracture (odds ratio [OR] 0.62, 95% confidence interval [CI] 0.43-0.90; OR 0.67, 95% CI 0.49-0.92; OR 0.64, 95% CI 0.47-0.87; OR 0.58, 95% CI 0.48-0.69, respectively). Additionally, dipeptidyl peptidase-4 inhibitors (DPP4i) significantly reduced incidences of non-vertebral fracture, vertebral and hip fracture, and overall fracture risk (OR 0.34, 95% CI 0.25-0.45; OR 0.72, 95% CI 0.55-0.95; OR 0.67, 95% CI 0.55-0.82, respectively). Meanwhile, metformin also reduces overall fracture risk (OR 0.60, 95% CI 0.42-0.88). We observed no significant differences between the antidiabetic agents according to the specific fracture site or study time point. Most antidiabetic treatments except thiazolidinediones did not increase the risk of fractures compared with the placebo.

Although levodopa remains the gold standard for managing PD motor symptoms, it lacks neuroprotective and disease-modifying effects, highlighting the need for new neuroprotective therapies. Mitophagy, the selective mitochondrial degradation by autophagy, is critical for neuronal health. Oleanolic acid, a natural hepatoprotective compound, shows uncertain efficacy in PD treatment. This study investigated the neuroprotective effects and underlying mechanisms of oleanolic acid using the 1-methyl-4-phenylpyridinium (MPP⁺)-induced cellular model and the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD. In vitro, oleanolic acid demonstrated dopaminergic neuroprotection by reducing mitochondrial dysfunction and reactive oxygen species accumulation in PD cells. It upregulated the mitophagic protein DJ-1, enhancing the sequestration of damaged mitochondria into autophagosomes by mitophagy. DJ-1 knockdown attenuated oleanolic acid's neuroprotection, confirming DJ-1's role in oleanolic acid's action. In vivo, pre-treatment with oleanolic acid in MPTP-induced PD mice prevented PD-like motor symptoms, reduced neuronal death in the substantia nigra, and mitigated striatal neurodegeneration. Post-treatment with oleanolic acid not only reduced these effects but also increased Bcl-2 and DJ-1 levels in the substantia nigra and striatum. In vitro, oleanolic acid activated JNK for Sp1 upregulation and nuclear translocation, which induced DJ-1 expression. Computational modeling predicted that oleanolic acid likely interacts with JNK, suggesting this binding might be necessary for JNK-Sp1-DJ-1 axis activation for mitophagy-driven neuroprotection. These results highlight oleanolic acid's potential as a therapeutic agent in PD prevention and treatment via the JNK-Sp1-DJ-1 pathway.

While research on S. spinosa has historically focused on spinosad production, little is known about the broader spectrum of secondary metabolites encoded by its genome. Like Streptomyces, S. spinosa harbors numerous biosynthetic gene clusters (BGCs), many of which remain cryptic under standard laboratory conditions. In this study, the spinosyn gene cluster was deleted using the heat-sensitive vector pKC1139, generating the mutant strain S. spinosaΔSPN. The fermentation products of both the wild-type S. spinosa (B1) and S. spinosaΔSPN (B2) were analyzed through HPLC coupled with high-resolution tandem mass spectrometry (HRMS/MS). Data analysis was conducted using GNPS-based molecular networking and MestReNova. A total of seven metabolites were putatively annotated in the wild-type strain (B1), with spinosyns being the predominant compounds. In contrast, the mutant strain (B2) produced putatively linear and cyclic lipopeptides, including gageostatins and gageopeptins as the major metabolites. Additionally, the crude extract from S. spinosaΔSPN (B2) exhibited antibacterial activity, likely due to the production of lipopeptides, which are known for their antimicrobial properties. These findings indicate that deletion of the spinosyn gene cluster can activate cryptic biosynthetic pathways, leading to the discovery of novel bioactive compounds with potential applications in medicine.</p>","PeriodicalId":8287,"journal":{"name":"Archives of Pharmacal Research","volume":" ","pages":""},"PeriodicalIF":6.9,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We recruited 20 kidney transplant recipients and profiled their gut microbiota diversity and composition from stool samples collected before transplantation and at weeks 1 and 4 post transplantation via 16S rRNA sequencing. The TAC pharmacokinetic parameters were also collected. Associations between TAC metabolism status or pharmacokinetic parameters and gut microbiota diversity and composition were evaluated. Recipients with a fast TAC metabolism rate (C₀/D ratio < 1.05 ng/mL × 1/mg) presented significantly greater changes in both bacterial alpha and beta diversity metrics at 1 week post transplantation than did those with a slow metabolism rate (C₀/D ratio ≥ 1.05 ng/mL × 1/mg). Compared with slow metabolizers, fast metabolizers were associated with a significant increase in the abundance of three bacterial genera (Faecalibacterium, Clostridia vadinBB60, and Ruminococcus) and a significant decrease in the abundance of two bacterial species (Bacteroides plebeius and Parabacteroides goldsteinii). This study revealed links between gut microbiota diversity and composition and TAC metabolism rates in kidney transplant recipients during the early posttransplant period, underscoring the importance of investigating the gut microbiota as a contributor to TAC pharmacokinetic variability.

We confirmed interaction between VEGFA and CHI3L1 through immunoprecipitation. Furthermore, the combination treatment of the anti-CHI3L1 antibody and VEGFA siRNA inhibited cell growth but increased apoptotic cell death. Additionally, using the Human Base database, we found that CHI3L1 and VEGFA are associated with nicotinamide phosphoribosyltransferase (NAMPT). Furthermore, combining the anti-CHI3L1 antibody and NAMPT siRNA more effectively reduced cell growth and the expression of CHI3L1, VEGFA, and cell growth-related proteins, but significantly increased apoptosis-related proteins.

The third-generation drug pirtobrutinib, which binds non-covalently to BTK, is expected to overcome resistance mutations at the covalent binding Cys481 residue of the first and second-generation drugs that covalently bind to BTK. However, some newly identified non-Cys481 resistance mutations to pirtobrutinib have shown their co-resistance to some of the covalent inhibitors, and this leaves a major unmet need that is promoting the development of next-generation BTK-targeted therapeutics. More non-covalent BTK inhibitors with differentiated binding modes are under development, and the ongoing development focus of next-generation therapeutics involves new and alternative directions to target BTK using dual-binding inhibitors and degraders of BTK, as well as its allosteric inhibitors. Recent exploration of the differentiated features of BTK inhibitors in various aspects has shown the possible link between their different features and different functional and therapeutic consequences. This review summarizes the key differentiated features of the BTK inhibitors approved by the FDA and others under development to add knowledge for their therapeutic application and future development.
