Cognitive deficiency is one of the fundamental characteristics of late-onset depression (LOD). Luteolin (LUT) possesses antidepressant, anti-aging, and neuroprotective properties, which can dramatically enhance cognition. The altered composition of cerebrospinal fluid (CSF), which is involved in neuronal plasticity and neurogenesis, directly reflects the physio-pathological status of the central nervous system. It is not well known whether the effect of LUT on LOD is in association with a change ...[more]

Comparative proteomics analysis of growth-primed adult dorsal root ganglia reveals key molecular mediators for peripheral nerve regeneration

Project description:Peripheral nerve injuries due to physical insults or chronic diseases are quite common, yet no pharmacological therapies are available for the effective repair of injured nerves. The slow growth rate of adult nerves and insufficient access to growth factors pose major hurdles in timely reinnervating target tissues and restoring functions after nerve injuries. A better understanding of the molecular changes that occur during the immediate regenerative reprogramming of neurons, stated here as in vivo priming, following nerve injury may reveal ideal candidates for future therapies. Hence, molecular profiling of neuronal soma within the first week of nerve injury has been the gold standard for revealing molecular candidates critical for nerve regeneration. A complementary in vitro regenerative priming approach was recently shown to induce enhanced outgrowth in adult sensory neurons. In this work, we exploited the in vitro priming model to reveal novel candidates for adult nerve regeneration. We performed the whole tissue proteomics analysis of in vitro primed DRGs and compared their molecular profile with that of the in vivo primed, and control DRGs. Through this approach, we identified several commonly and uniquely altered molecules in the in vitro and in vivo primed DRGs that have the potential to modulate adult nerve regrowth. We further validated the growth inducing potential of mesencephalic astrocyte-derived neurotrophic factor (MANF), one of the hits identified in our proteomics analysis, in primary adult sensory neurons. Overall, this study showed that in vitro priming partially reproduces the molecular features in in vivo primed adult sensory neurons. The shortlisted candidates presented here from the two priming approaches may serve as potential therapeutic targets for adult nerve regeneration.

Inhibition of p300 Lysine Acetyltransferase activity by Luteolin reduces tumor growth in head and neck squamous cell carcinoma (HNSCC) xenograft mouse model [mRNA]

Project description:Chromatin acetylation is attributed with distinct functional relevance with respect to gene expression in normal and diseased conditions thereby leading to a topical interest in the concept of epigenetic modulators and therapy. We report here the identification and characterization of the acetylation inhibitory potential of an important dietary flavonoid, luteolin. Luteolin was found to inhibit p300 acetyltransferase with competitive binding to the acetyl CoA binding site. Luteolin treatment in a xenografted tumor model of head and neck squamous cell carcinoma (HNSCC), led to a dramatic reduction in tumor growth within 4 weeks corresponding to a decrease in histone acetylation. Cells treated with luteolin exhibit cell cycle arrest and decreased cell migration. Luteolin treatment led to an alteration in gene expression and miRNA profile including up-regulation of p53 induced miR-195/215, let7C; potentially translating into a tumor suppressor function. It also led to down-regulation of oncomiRNAs such as miR-135a, thereby reflecting global changes in the microRNA network. Furthermore, a direct correlation between the inhibition of histone acetylation and gene expression was established using chromatin immunoprecipitation on promoters of differentially expressed genes. A network of dysregulated genes and miRNAs was mapped along with the gene ontology categories, and the effects of luteolin were observed to be potentially at multiple levels: at the level of gene expression, miRNA expression and miRNA processing. Cells treated with luteolin exhibit cell cycle arrest and decreased cell migration. Luteolin treatment led to an alteration in gene expression and mRNA profile

Luteolin attenuates lipid dysregulation and insulin resistance thorough interplay of liver and adipose tissue in diet-induced obese mice

Project description:Analysis of effect of luteolin on lipid metabolism at gene expression level. The hypothesis tested in the present study was that luteolin treatment with obesogenic diet suppressed the hepatic lipogenesis pathways. Conversely, in adipose tissue, luteolin stimulated the lipogenesis pathway and it also simultaneously increased the expression of genes controlling lipolysis and TCA cycle. Results provide important information about the effect on diet-induced obesity and its metabolic complications. Total RNA of liver and adipose tissues was obtained from normal diet, high-fat diet and luteolin added high-fat diet-fed mice and mRNA expression-associated with lipid metabolism was measured.

Luteolin protects against obese sarcopenia in mice with high-fat diet-induced obesity by ameliorating inflammation and protein degradation in muscle

Project description:Although there are studies on obesity and sarcopenia, our understanding of obesity-mediated sarcopenia is insufficient. Additionally, no studies have investigated the application of luteolin in sarcopenia. We attempted to determine the effect of luteolin on obese sarcopenia in mice with high-fat diet (HFD)-induced obesity. Luteolin exerted suppressive effects on obesity, inflammation, and protein degradation in HFD-fed obese mice. Luteolin inhibited lipid infiltration into the muscle and decreased p38 and JNK activity and mRNA expression of inflammatory factors, such as TNFα, Tlr2, Tlr4, MCP1, and MMP2, in the muscle. Suppression of muscle inflammation by luteolin led to the inhibition of myostatin, FoxO, atrogin, and MuRF expression, which reduced protein degradation and improved muscle function. This is the first study to demonstrate that luteolin exerts a protective effect against obese sarcopenia, as its anti-obesity and anti-inflammatory activities inhibited protein degradation. Therefore, luteolin may be a useful supplement for prevention of obese sarcopenia.

Luteolin attenuates hepatic and adipocyte fibrosis and insulin resistance by targeting toll-like receptors signaling pathway in diet-induced obese mice

Project description:The flavonoid luteolin possess a variety of anti-inflammatory properties, but little has known about the detailed mechanisms linked to the anti-metabolic syndrome action of luteolin based on the integration of the transcriptional profile and the phenotype biomarkers. The aim of this study was to investigate the protective role of luteolin on inflammation-mediated metabolic diseases, focusing on its role in modulating toll-like receptor (TLR) signaling pathway triggered up-regulation of pro-inflammatory cytokines. Above all, it provides novel insights into the effect of luteolin on the link among adiposopathy, insulin resistance, hepatic steatosis and fibrosis. C57BL/6J mice were fed a normal, high-fat, and high-fat + 0.005% (w/w) luteolin diet for 16 weeks. In this study, (a) luteolin treatment resulted in an improvement in chronic low-grade inflammation by modulating TLR-signaling pathway resulting in reduced pro-inflammatory cytokines and macrophage accumulation; (b) there is a positive relationship of TLR5, MKK4/7, p38 and JNK-related gene expressions and lipogenesis in luteolin-treated obese mice, which is linked to an attenuation of hepatic lipotoxicity with an increased hepatic anti-oxidant system; (c) luteolin prevented hepatic and adipocyte fibrosis by decreasing ECM accumulation and cathepsin gene expressions; (d) Emr1 and Ccl7 genes, important markers inducing low-grade inflammation, are affected by advancing age as well as body weight, and luteolin treatment normalized those gene expressions; (e) luteolin treatment improved insulin resistance by normalizing pancreatic islet dysfunction, and differentially modulating the plasma GLP-1 and GIP levels. Taken together, luteolin ameliorates the deleterious effects of diet-induced obesity and its comorbidity.

PC-3 cells were treated for 24h with DMSO, 60Î¼M luteolin (Lut), 60Î¼M gefitinib (Gef) or their co-administration (Lut+Gef). Each sample was run in duplicate.
