Abstract
OBJECTIVE Microglia in the central nervous system regulate neuroinflammation that leads to a wide range of neuropathological alterations. The present study investigated the anti-neuroinflammatory properties of nobiletin (Nob) derivative, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone (5-Ac-Nob), in lipopolysaccharide (LPS)-activated BV2 microglia. MATERIALS AND METHODS By using the MTT assay, Griess method, flow cytometry, and enzyme-linked immunosorbent assay (ELISA), we determined the cell viability, the levels of nitric oxide (NO), reactive oxygen species (ROS), and pro-inflammatory factors (interleukin 1 beta; IL-1β, interleukin 6; IL-6, tumor necrosis factor alpha; TNF-α and prostaglandin E2; PGE2) in LPS-stimulated BV2 microglia. Toll-like receptor 4 (TLR4)-mediated myeloid differentiation primary response gene 88 (MyD88)/nuclear factor-kappa B (NF-κB), mitogen-activated protein kinase (MAPK) signaling pathway and signal transducer and activator of transcription 3 (STAT3) were measured by western blotting. Analysis of NO generation and mRNA of pro-inflammatory cytokines was confirmed in the zebrafish model. RESULTS 5-Ac-Nob reduced cell death, the levels of NO, ROS, inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), and pro-inflammatory factors in LPS-activated BV-2 microglial cells. TLR4-mediated MyD88/NF-κB and MAPK pathway (p38, ERK and JNK) after exposure to 5-Ac-Nob was also suppressed. Moreover, 5-Ac-Nob inhibited phosphorylated STAT3 proteins expression in LPS-induced BV-2 microglial cells. Furthermore, we confirmed that 5-Ac-Nob decreased LPS-induced NO generation and mRNA of pro-inflammatory cytokines in the zebrafish model. CONCLUSIONS Our findings suggest that 5-Ac-Nob represses neuroinflammatory responses by inhibiting TLR4-mediated signaling pathway and STAT3. As a result of these findings, 5-Ac-Nob has potential as an anti-inflammatory agent against microglia-mediated neuroinflammatory disorders.

Cell Biochem Funct 2024; 42:e4056. [PMID: 38812104 DOI: 10.1002/cbf.4056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 05/09/2024] [Accepted: 05/12/2024] [Indexed: 05/31/2024]
Abstract
Previous studies suggested that central nervous system injury is often accompanied by the activation of Toll-like receptor 4/NF-κB pathway, which leads to the upregulation of proapoptotic gene expression, causes mitochondrial oxidative stress, and further aggravates the inflammatory response to induce cell apoptosis. Subsequent studies have shown that NF-κB and IκBα can directly act on mitochondria. Therefore, elucidation of the specific mechanisms of NF-κB and IκBα in mitochondria may help to discover new therapeutic targets for central nervous system injury. Recent studies have suggested that NF-κB (especially RelA) in mitochondria can inhibit mitochondrial respiration or DNA expression, leading to mitochondrial dysfunction. IκBα silencing will cause reactive oxygen species storm and initiate the mitochondrial apoptosis pathway. Other research results suggest that RelA can regulate mitochondrial respiration and energy metabolism balance by interacting with p53 and STAT3, thus initiating the mitochondrial protection mechanism. IκBα can also inhibit apoptosis in mitochondria by interacting with VDAC1 and other molecules. Regulating the biological role of NF-κB signaling pathway in mitochondria by targeting key proteins such as p53, STAT3, and VDAC1 may help maintain the balance of mitochondrial respiration and energy metabolism, thereby protecting nerve cells and reducing inflammatory storms and death caused by ischemia and hypoxia.

Identification of central regulators related to abdominal fat deposition in chickens based on weighted gene co-expression network analysis. Poult Sci 2024; 103:103436. [PMID: 38237326 PMCID: PMC10828593 DOI: 10.1016/j.psj.2024.103436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/25/2023] [Accepted: 01/03/2024] [Indexed: 02/03/2024] Open
Abstract
Abdominal fat (AF) is one of the most important economic traits in chickens. Excessive AF in chickens will reduce feed utilization efficiency and negatively affect reproductive performance and disease resistance. However, the regulatory network of AF deposition needs to be further elucidated. In the present study, 300 one-day-old female Wannan chickens were reared to 17 wk of age, and 200 Wannan hens were selected to determine the abdominal fat percentage (AFP). Twenty AF tissue samples with the lowest AFP were selected as the low abdominal fat group (L-AFG), and 20 AF tissue samples with the highest AFP were selected as the high abdominal fat group (H-AFG). Eleven samples from L-AFG and 14 samples from H-AFG were selected for RNA-seq and used for weighted gene co-expression network analysis (WGCNA). Among the 25 RNA-seq samples, 5 samples with the lowest and highest AFP values were selected for differential expression gene analysis. Compared with the L-AFG, 225 and 101 genes were upregulated and downregulated in the H-AFG, respectively. A total of 20,503 genes were used to construct the WGCNA, and 44 co-expression gene modules were identified. Among these modules, 3 modules including turquoise, darkorange2, and floralwhite were identified as significantly associated with AFP traits. Furthermore, several genes including acyl-CoA oxidase 1 (ACOX1), stearoyl-CoA desaturase (SCD), aldehyde dehydrogenase 6 family member A1 (ALDH6A1), jun proto-oncogene, AP-1 transcription factor subunit (JUN), and fos proto-oncogene, AP-1 transcription factor subunit (FOS) involved in the "PPAR signaling pathway," "fatty acid metabolism," and "MAPK signaling pathway" were identified as central regulators that contribute to AF deposition. These results provide valuable information for further understanding of the gene expression and regulation of AF traits and contribute to future molecular breeding for AF in chickens.

Abstract
OBJECTIVE Attention-deficit hyperactivity disorder (ADHD) is a psychiatric disorder characterized by symptoms of inattention, hyperactivity, and impulsivity. Stimulant medication is the main pharmacological treatment for ADHD. However, the traditional pharmacological treatments may have significant side effects; therefore, non-pharmacological approaches are needed. Thus, there has been growing interest in alternative herbal treatments. The aim of this review was to comprehensively assess the current evidence for plant-based treatment of ADHD in human and animal models, as well as their ability to modulate the inflammatory process. METHODS This study was an integrative review of the current evidence for the plant-based treatment of ADHD. The research involved using literature available on PubMed and Scopus databases. FINDINGS Spontaneously hypersensitive rats treated with baicalin exhibited significant reductions in locomotion, increased spatial learning skills, and increased levels of dopamine in the striatum. Supplementation with Sansonite improved memory and attention capacity. In human studies, Ginkgo biloba significantly improved the symptoms of inattention and reduced memory impairment. In studies conducted using Korean Red ginseng, Klamath, and Crocus sativus L., the patients showed significant improvements in symptoms of inattention and hyperactivity/impulsivity. Furthermore, we demonstrated that the identified plants modulate the inflammatory process through pro-inflammatory and anti-inflammatory cytokines, nitric oxide, Th cells, Toll-like receptor 4, and mitogen-activated protein kinases. CONCLUSION All the studies included in this review focused on plants with demonstrated potential against inflammatory processes, positioning them as promising candidates for ADHD treatment, due to their potential to attenuate or even prevent neuroinflammatory mechanisms.

Abstract
The nuclear factor kappa B (NF-κB) pathway has emerged as a pivotal player in the pathogenesis of various diseases, including neurodegenerative illnesses like Alzheimer's disease (AD). The involvement of the NF-κB pathway in immune system responses, inflammation, oxidative stress, and neuronal survival highlights its significance in AD progression. We discuss the advantages of NF-κB pathway inhibition, including the potential to mitigate neuroinflammation, modulate amyloid beta (Aβ) production, and promote neuronal survival. However, we also acknowledge the limitations and challenges associated with this approach. Balancing the fine line between dampening inflammation and preserving physiological immune responses is critical to avoid unintended consequences. This review combines current knowledge on the NF-κB pathway's intricate involvement in AD pathogenesis, emphasizing its potential as a therapeutic target. By evaluating both advantages and limitations, we provide a holistic view of the feasibility and challenges of NF-κB pathway modulation in AD treatment. As the quest for effective AD therapies continues, an in-depth understanding of the NF-κB pathway's multifaceted roles will guide the development of targeted interventions with the potential to improve AD management.
