Behaviour of Tunisian Psammomys obesus fed high-calorie diets: biochemical disturbance and histopathological alterations. Arch Physiol Biochem 2024:1-17. [PMID: 38982878 DOI: 10.1080/13813455.2024.2375983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Accepted: 06/26/2024] [Indexed: 07/11/2024]
Abstract
This work investigated the biochemical disturbances and histological alteration in Psammomys obesus animal model fed different high calorie diets (HCDs) during three months. Four diets were used: a low-calorie natural diet, Chenopodiaceae halophyte plant used as control (LCD), a high standard carbohydrate diet rich in protein, HCD 0, a high carbohydrate diet rich in two concentrations of fat, HCD 1 and HCD 2. All animals having received HCDs developed dyslipidemia after one month of experiment with distinction of different sub-groups developing or not obesity and diabetes. HCDs induced a remarkable increasing in blood cholesterol, LDL-cholesterol and triglyceride levels indicating a fast induction of dyslipidemia and a significant increase of aminotransaminases activities revealing a pronounced hepatotoxicity. Animal developing diabetes showed a severe hepatic injury, a degeneration of the adipose tissue and a significant reduction of retinal thickness. P. obesus seems to be an excellent animal model to investigate nutritional metabolic diseases.

Hong S, Lazerka N, Jeon BJ, Kim JD, Erdenebileg S, Nho CW, Yoo G. Osteogenic Effects of the Diospyros lotus L. Leaf Extract on MC3T3-E1 Pre-Osteoblasts and Ovariectomized Mice via BMP2/4 and TGF β Pathways. Nutrients 2024; 16:1247. [PMID: 38674937 PMCID: PMC11053699 DOI: 10.3390/nu16081247] [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: 03/21/2024] [Revised: 04/12/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
Osteoporosis, a disease defined by the primary bone strength due to a low bone mineral density, is a bone disorder associated with increased mortality in the older adult population. Osteoporosis is mainly treated via hormone replacement therapy, bisphosphates, and anti-bone resorption agents. However, these agents exert severe side effects, necessitating the development of novel therapeutic agents. Many studies are focusing on osteogenic agents as they increase the bone density, which is essential for osteoporosis treatment. Here, we aimed to investigate the effects of Diospyros lotus L. leaf extract (DLE) and its components on osteoporosis in MC3T3-E1 pre-osteoblasts and ovariectomized mice and to elucidate the underlying related pathways. DLE enhanced the differentiation of MC3T3-E1 pre-osteoblasts, with a 1.5-fold elevation in ALP activity, and increased the levels of osteogenic molecules, RUNX family transcription factor 2, and osterix. This alteration resulted from the activation of bone morphogenic protein 2/4 (BMP2/4) and transformation of growth factor β (TGF β) pathways. In ovariectomized mice, DLE suppressed the decrease in bone mineral density by 50% and improved the expression of other bone markers, which was confirmed by the 3~40-fold increase in osteogenic proteins and mRNA expression levels in bone marrow cells. The three major compounds identified in DLE exhibited osteogenic and estrogenic activities with their aglycones, as previously reported. Among the major compounds, myricitrin alone was not as strong as whole DLE with all its constituents. The osteogenic activity of DLE was partially suppressed by the inhibitor of estrogen signaling, indicating that the estrogenic activity of DLE participated in its osteogenic activity. Overall, DLE suppresses osteoporosis by inducing osteoblast differentiation.

Abstract
Diospyros lotus L, F. Ebenaceae, is an edible fruit that is widely distributed in China and other Asian countries. Presently, Diospyros lotus L can be used to treat patients with diabetes; however, its chemical composition and pharmacological profiles remain to be elucidated. This study investigated the potential bioactive compounds of Diospyros lotus L and their mechanisms of action using LC-MS and network pharmacology analysis. First, the components of Diospyros lotus L were identify using a reliable strategy for UHPLC-Q-Exactive Orbitrap mass spectrometry combined with parallel reaction monitoring (PRM) in the negative ion mode. Second, a network pharmacology study, including target gene prediction and functional enrichment, was applied to screen the main quality markers of Diospyros lotus L and explore its potential mechanism for the treatment of diabetes. The results showed that a total of 159 compounds were identified from Diospyros lotus L, among which, 140 were reported for the first time. Furthermore, 40 active components, such as quercetin, luteolin, and kaempferol, were proposed as active components of Diospyros lotus L for the treatment of diabetes based on network pharmacology analysis. In addition, 92 relevant antidiabetic targets were mainly related to positive regulation of transcription from the RNA polymerase II promoter, extracellular space, and protein binding, suggesting the involvement of TNF, PI3K-Akt, and HIF-1 signaling pathways in the antidiabetic effect of Diospyros lotus L. Our results may provide a useful approach to identify potential active components and molecular mechanisms of Diospyros lotus L for the treatment of diabetes.

Abstract
Obesity is a worldwide epidemic associated with many health problems. One of the new trends in health care is the emphasis on regular exercise and a healthy diet. Zeaxanthin (Zea) is a carotenoid with many beneficial effects on human health. The aim of this study was to investigate whether the combination of Zea and exercise had therapeutic effects on obesity induced by an HFD in rats. Sixty male Wistar rats were randomly divided into five groups of twelve: rats fed a standard diet; rats fed a high-fat diet (HFD); rats fed an HFD with Zea; rats fed an HFD with Exc; and rats fed an HFD with both Zea and Exc. To induce obesity, rats were fed an HFD for twelve weeks. Then, Zea and exercise were introduced with the HFD for five weeks. The results showed that the HFD significantly increased visceral adipose tissue, oxidative stress, and inflammation biomarkers and reduced insulin, high-density lipoprotein, and antioxidant parameters. Treatments with Zea, Exc, and Zea plus Exc reduced body weight gain, triacylglycerol, glucose, total cholesterol, and nitric oxide levels and significantly increased catalase and insulin compared with the HFD group. This study demonstrated that Zea administration and Exc performance appeared to effectively alleviate the metabolic alterations induced by an HFD. Furthermore, Zea and Exc together had a better effect than either intervention alone.

Abstract
Switching myofibers from the fast-glycolytic type to the slow-oxidative type is associated with an alleviation of the symptoms associated with various cardiometabolic diseases. This study investigates the effect of Vitis vinifera Jingzaojing leaf and shoot extract (JLSE), which is rich in phenolic compounds, on the regulation of skeletal muscle fiber-type switching, as well as the associated underlying mechanism. Male C57BL/6N mice were supplemented orally with vehicle or JLSE (300 mg/kg) and subjected to treadmill exercise training. After four weeks, mice in the JLSE-supplemented group showed significantly improved exercise endurance and mitochondrial oxidative capacity. JLSE supplementation increased the expression of sirtuin 6 and decreased Sox6 expression, thereby elevating the number of mitochondria and encouraging fast-to-slow myofiber switching. The results of our experiments suggest that JLSE supplementation reprograms myofiber composition to favor the slow oxidative type, ultimately enhancing exercise endurance.

Abstract
Steatohepatitis, fibrosis, and cirrhosis are common pathological features in the progression of hepatic steatosis. In the current work, we investigated the effect of germinated barely on the structure and function of the liver and its regulatory mechanism on SDC1 gene expression in a steatohepatitis rat model. Forty-eight adult male white Wistar rats were randomly divided into four groups: Group I, control; Group II, rats fed a germinated barley diet; Group III, rats fed a high-fat diet (HFD); and Group IV, rats fed both germinated barley (GB) and a high-fat diet for 14 weeks. Biochemical, histopathological, immunohistochemical, and morphometric studies, as well as qRT-PCR, were used to analyze the effect of germinated barley on steatohepatitis. The rats in Group IV had a lower liver index percentage and improved altered lipid profile and liver function tests compared to those in Group III. Supplementation of GB with a HFD ameliorated the histopathological features in the livers of rats fed a HFD, decreased the percentage of CD68-positive macrophages, and lowered the upregulated expression of SDC1. Supplementation of a HFD with GB prohibited the deterioration of liver function, lipid profile, and alteration of liver structure; it also decreased the associated hepatic inflammation and downregulated SDC1 in liver tissue.

Abstract
The present study demonstrated the anti-obesity effects of enzyme-treated celery extract (ECE) in mice on high-fat diet (HFD). In vitro studies showed that ECE has anti-adipogenic properties by inhibiting lipid accumulations in adipose cells. In vivo studies indicated that the administration of ECE markedly prevented HFD-induced body weight gain, food efficiency ratio, and epididymal fat and liver weights. ECE reduced lipid parameters, cardiac risk factor, and atherogenic index in obese mice. ECE prevented a diabetes state by improving adipokines levels, reducing glucose levels, and preventing insulin resistance. Moreover, ECE prevented HFD-induced liver damage by preventing hepatic steatosis and upregulation of liver antioxidant enzymes. The mechanism of ECE was partially investigated to involve the activation of 5' adenosine monophosphate-activated protein kinase and hence the downregulation of CCAAT/enhancer binding protein α and peroxisome proliferator-activated receptor γ by ECE. Our results suggest that ECE could be used as functional food materials for the prevention of obesity. PRACTICAL APPLICATIONS: Apium graveolens is a popular plant with nutritive and medicinal benefits. It contains bioactive compounds such as apiin, apigenin, and luteolin. However, these compounds are rendered insoluble due to their interaction with polysaccharides in the cell wall thus making them less bioavailable. Hydrolyzing them could increase the yield of bioactive compounds in celery. This pilot study demonstrates that pectinase-treated celery extract has anti-obesity effects. The results of this research demonstrate the use of enzymes in improving the biological activities of plant extracts and suggest the use of enzyme-assisted extraction techniques in the industrial production of health functional food from celery.

Rice bran oil ameliorates inflammatory responses by enhancing mitochondrial respiration in murine macrophages. PLoS One 2019; 14:e0222857. [PMID: 31603952 PMCID: PMC6788716 DOI: 10.1371/journal.pone.0222857] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2019] [Accepted: 08/23/2019] [Indexed: 01/06/2023] Open
Abstract
Previous studies have revealed the anti-inflammatory properties of rice bran oil (RBO), but the detailed mechanisms are poorly understood. Recent studies on the molecular/cellular anti-inflammatory mechanisms of dietary components have demonstrated that mitochondrial respiration plays a key role in macrophage functioning. Since dietary lipids are major substrates for mitochondrial respiration through β-oxidation, the current study examined whether RBO regulates inflammatory responses by modulating mitochondrial energy metabolism. Palm oil (PO), enriched with palmitic acid which are known to be effectively taken up by cells and used for oxidative phosphorylation, served as a positive control. In the in vitro model of LPS-stimulated RAW 264.7 murine cells, the levels of pro-inflammatory cytokines (IL-6 and TNF-α) in the culture supernatant were significantly reduced by RBO treatment. In contrast, secretion of the anti-inflammatory cytokine IL-10 was upregulated by RBO. Transcription of genes encoding inflammatory mediator molecules (COX-2 and iNOS) and expression of activation markers (CD80, CD86, and MHC-II) in LPS-stimulated RAW 264.7 cells were suppressed by RBO. Mitochondrial respiration (as assessed by an extracellular flux analyzer) increased upon RBO treatment, as the basal respiration, maximal respiration, ATP production, and spare respiratory capacity were upregulated. In an in vivo study, C57BL/6 mice were fed a negative control diet containing corn oil (CO), PO, or RBO for 4 weeks, and bone marrow-derived macrophages (BMDM) were isolated from their tibias and femurs. In pro-inflammatory M1-polarized BMDM (M1-BMDM), the RBO-induced suppression of IL-6 and TNF-α was recapitulated in vivo. Mitochondrial respiration in M1-BMDM also increased following the RBO intervention and the PO control treatment as compared to CO fed negative control. Overall, the current study for the first time demonstrates that RBO regulates inflammatory responses in murine macrophages by upregulating mitochondrial respiration. Further clinical studies are required to validate the animal study.
