    Abstract BACKGROUND: The association of gut microbiota with cancer etiology and prognosis has been demonstrated in humans and rodents but has not been studied in dogs with different types of tumors. HYPOTHESIS/OBJECTIVES: To analyze microbiome composition according to tumor progression based on metastasis, recurrence, and therapeutic response in canine tumors. ANIMALS: Thirty‐two client‐owned dogs were divided into 3 groups: healthy (n = 9), with lymphoma (n = 12), with nonlymphoid tumors (n = 11). METHODS: Retrospective case series included animals were divided into subgroups according to the nature and severity of their tumors. Feces were screened for the 16S rRNA gene. RESULTS: Overall, alpha diversity was significantly reduced in dogs with tumors (n = 23; 12 lymphoid and 11 nonlymphoid) compared to healthy dogs (n = 9). Bacteroides had lower abundance in canine tumors at genus level. Staphylococcus showed significantly reduced abundance in dogs with aggressive tumor progression. Higher white blood cell (WBC) and neutrophil counts and lower hematocrit were significant in dogs with aggressive tumor. Spearman's rank correlation coefficient analysis revealed several measurements that showed moderate to strong correlations, including Coprococcus with total WBC count, neutrophil count, and hematocrit in the aggressive tumor group, and Saccharimonas with serum albumin and sodium concentration in all tumor dogs. CONCLUSION AND CLINICAL IMPORTANCE: The diversity of the gut microbiome was significantly reduced in dogs with tumors compared to healthy dogs. Correlations were found between changes in blood measurements and changes in microbiome composition in relation to paraneoplastic syndrome.

    Abstract To date, all species in the genus Salicibibacter have been isolated in Korean commercial kimchi. We aimed to describe the taxonomic characteristics of two strains, NKC5-3ᵀ and NKC21-4ᵀ, isolated from commercial kimchi collected from various regions in the Republic of Korea. Cells of these strains were rod-shaped, Gram-positive, aerobic, oxidase- and catalase-positive, non-motile, halophilic, and alkalitolerant. Both strains, unlike other species of the genus Salicibibacter, could not grow without NaCl. Strains NKC5-3ᵀ and NKC21-4ᵀ could tolerate up to 25.0% (w/v) NaCl (optimum 10%) and grow at pH 7.0–10.0 (optimum 8.5) and 8.0–9.0 (optimum 8.5), respectively; they showed 97.1% 16S rRNA gene sequence similarity to each other and were most closely related to S. kimchii NKC1-1ᵀ (97.0% and 96.8% similarity, respectively). The genome of strain NKC5-3ᵀ was nearly 4.6 Mb in size, with 4,456 protein-coding sequences (CDSs), whereas NKC21-4ᵀ genome was nearly 3.9 Mb in size, with 3,717 CDSs. OrthoANI values between the novel strains and S. kimchii NKC1-1ᵀ were far lower than the species demarcation threshold. NKC5-3ᵀ and NKC21-4ᵀ clustered together to form branches that were distinct from the other Salicibibacter species. The major fatty acids in these strains were anteiso-C₁₅:₀ and anteiso-C₁₇:₀, and the predominant menaquinone was menaquinone-7. The polar lipids of NKC5-3ᵀ included diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), and five unidentified phospholipids (PL), and those of NKC21-4ᵀ included DPG, PG, seven unidentified PLs, and an unidentified lipid. Both isolates had DPG, which is the first case in the genus Salicibibacter. The genomic G + C content of strains NKC5-3ᵀ and NKC21-4ᵀ was 44.7 and 44.9 mol%, respectively. Based on phenotypic, genomic, phylogenetic, and chemotaxonomic analyses, strains NKC5-3ᵀ (= KACC 22040ᵀ = DSM 111417ᵀ) and NKC21-4ᵀ (= KACC 22041ᵀ = DSM 111418ᵀ) represent two novel species of the genus Salicibibacter, for which the names Salicibibacter cibarius sp. nov. and Salicibibacter cibi sp. nov. are proposed.

    Abstract Aims: We examined renal kallikrein-kinin system (KKS) apoptosis and its related signaling pathway in rat podocytes. In addition, we studied the relationship of cannabinoid receptor 1 (CB(1)R) with high glucose and BK receptors.
    Main methods: Cell viability was determined by an MTT assay and apoptosis by DNA fragmentation assay, while gene expression was investigated by RT-PCR. Protein expression was analyzed by Western blot analysis. A chemical inhibitor or siRNA transfection was used to inhibit B1R, B2R, and CB(1)R signaling.
    Key findings: High glucose (25 mM) treatment decreased cell viability and increased DNA fragmentation. High glucose-induced DNA fragmentation and PARP and caspase-3 activations were blocked by both [des-Arg(10)]-HOE 140 (a B1R antagonist) and HOE 140 (a B2R antagonist). High glucose also increased Akt phosphorylation, ER stress-related protein expression, and NF-κB/I-κB phosphorylation in podocytes, which was blocked by both [des-Arg(10)]-HOE 140 and HOE 140. In addition, B1R and B2R siRNA transfections prevented high glucose-induced Akt and NF-κB activations in rat podocytes. Moreover, AM251 (a CB(1)R antagonist) treatment and CB(1)R siRNA transfection blocked the high glucose-induced stimulation of BK receptor expression, Akt activation, and NF-κB activation.
    Significance: Our study suggests that hyperglycemia induces apoptosis via the stimulation of B1R and B2R expression through CB(1)R activation in rat podocytes in vitro, which is associated with the development of diabetic nephropathy.

    Abstract A high-fat diet (HFD) induces low-grade, chronic inflammation throughout the body including the hypothalamus, a key brain region involved in the control of satiety and energy expenditure in central nervous system (CNS). Kimchi is a traditional fermented Korean food, which is recognized as a healthy food. In this study, we evaluated its ability to suppress the obesity-induced inflammation in mice fed an HFD. Male C57BL/6 mice were fed an HFD or HFD with kimchi (pH 5.2 ∼ 5.8). Oral administration of kimchi significantly reduced the body weight, fat mass gain, and levels of pro-inflammatory cytokines in serum. Furthermore, kimchi diminished the HFD-induced activation of astrocyte and microglial cells (reactive gliosis, a hallmark of CNS injury and inflammation) in hypothalamus region. IgG accumulation assay showed that kimchi ingestion suppressed HFD-induced breakage of the blood brain barrier (BBB) via upregulating the expression of tight junction molecules in cerebrovascular endothelial cells. In addition, kimchi modulated gut microbiome profiles, which showed an increase in the abundance of Akkermansia muciniphila. Moreover, kimchi enhanced acetate level and BBB integrity in A. muciniphila-colonized gnotobiotic mice. These results suggest that kimchi may exert beneficial effects to prevent and ameliorate obesity and associated neuroinflammation by changing gut microbiota composition and short-chain fatty acids production.
