Extract of Triticum aestivum Sprouts Suppresses Acetaminophen-Induced Hepatotoxicity in Mice by Inhibiting Oxidative Stress. Molecules 2021; 26:molecules26216336. [PMID: 34770745 PMCID: PMC8587876 DOI: 10.3390/molecules26216336] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/06/2021] [Accepted: 10/15/2021] [Indexed: 11/26/2022] Open
Abstract
Wheat (Triticum aestivum L.) is the oldest known food crop, and many studies have reported that wheat shoots (i.e., wheatgrass) possess anti-cancer, anti-inflammatory, and antioxidant activities. However, the potentially ameliorative effect of wheat shoots on hepatotoxicity caused by high doses of N-acetyl-para-aminophenol (acetaminophen, APAP) has yet to be reported. C57BL/6 mice received daily oral TAE (100 or 200 mg/kg), positive control (silymarin 100 mg/kg), or negative control (saline vehicle) treatments for 7 days prior to intraperitoneal APAP injection. Histological, serum (ELISA), Western blotting, and quantitative PCR analyses of excised liver tissues were then performed. Pre-treatment with TAE (100 or 200 mg/kg) ameliorated APAP-induced pathological damage (i.e., hepatotoxic lesions), reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and also ameliorated APAP-induced increases in oxidative stress, thereby inhibiting oxidative liver damage and reducing the expression of inflammatory cytokines. In addition, TAE pre-treatment inhibited the expression of Cytochrome P4502E1 (CYP2E1), which is a key enzyme in the onset of APAP-induced hepatotoxicity, suppressed the expression of the target proteins regulated by the antioxidant enzyme Nrf2, and suppressed hepatocyte apoptosis. These findings suggest that TAE is an attractive therapeutic candidate that exhibits potential hepatoprotective activity by inhibiting oxidative stress, inflammation, apoptosis, and liver damage.

Abstract
Heavy metal contaminated water is a great concern because of its high toxiciy, non-biodegradability, and bioaccumulation. Therefore, non-contaminated water is fundamental for a healthy life. Special attention is paid to the health-promoting ingredients of germinated whole cereal products. This study aimed to (1) examine the potentially harmful effects of Cu, Mn, and Zn on rat livers and brains, and (2) the potentially protective action of wheat and barley grasses against the expected harmful effects of these metals. The rats were treated with water contaminated by heavy metals (HMs) and germinated wheat and barley for 60 days. The rat liver functions and histopathological examinations were analyzed. Comet assay was evaluated to assess the damage in the DNA of rat livers and brains. The results indicated a significant alteration in liver functions in rats exposed to HMs; however, wheat and barley grasses at high doses decreased the harmful effects. An insignificant difference was noticed in total protein, albumin, and globulin of rats treated with HMs compared with the control. A significant increase in the serum and liver levels of HMs was recorded; however, they were reduced by wheat and barley grasses. Rat livers treated with HMs exhibited severe histological effects. The groups treated with wheat and barley grasses showed a normal liver architecture. A significant increase in DNA damage in the livers and brains was observed in rats treated with HMs, which was reduced when treated with wheat and barley grasses. Thus, using germinated seeds is promising to avoid damaging of HMs.

Abstract
Plant sprout foods exhibit a lot of biological activities including anti-inflammatory, antioxidative, anticancer, antidiabetes, anti-infection, and antiviral activities. Up to the present moment, plant sprout foods have received much attention due to their abundance, good bioavailability, and health benefits for human. This review highlights the biological activities of different plant sprout foods (viz., broccoli sprout, buckwheat sprout, wheat sprout, mung bean sprout, soybean sprout, and adkuzi bean sprout) using in vitro model, animal model, and human model. Furthermore, the bioavailability of plant sprout foods is also discussed. PRACTICAL APPLICATIONS: A review of the literature was conducted to biological activities of plant sprout foods, in addition to a summary of health benefits and bioavailability of sprout foods. Several biological activities of plant sprout foods with in vitro and in vivo evidence are currently unexplored in clinical trials, because the effects of sprout foods on human tissues and cells measured by tube test do not recapitulate the actual in vivo effects. Moreover, the safety of chemoprevention strategies using sprout foods that to protect against environmental exposures and other oxidative stress-related pathologies is important. Further research is warranted to evaluate bioavailability of individual forms.

Abstract
To enlarge the applications of whole wheat grain (WWG) and wheat bran (WB) as functional ingredients in foodstuffs that can promote human health, researchers have explored bioprocessing approaches to improve the bioaccessibility of phenolic compounds from these food matrices and, subsequently, their biological effects. The objective of this study was to compare the composition in nutrients, anti-nutrients, and bioactive compounds of WWG and WB, and their respective bioprocessed products: sprouted wheat (GERM) and WB hydrolysate (stabilized by spray-drying [SPD] and microencapsulated [MEC]). In addition, to evaluate the functional properties of these ingredients, the bioaccessibility of phenolic compounds and their potential antioxidant and anti-inflammatory activities were monitored in different digestion steps. GERM had increased amounts of insoluble dietary fiber, higher diversity of oligosaccharides, and higher concentration of monosaccharides, free phosphorous, and phenolic compounds than WWG. SPD had improved content of soluble dietary fiber, oligosaccharides, monosaccharides, free phosphorous, and phenolic compounds (vs. WB), whereas MEC was mainly composed of protein and had nearly 2-fold lower content of SPD components. All the ingredients showed lower amounts of phytic acid as compared with raw materials. In all samples, hydroxycinnamic acids were the most representative polyphenols followed by minor amounts of hydroxybenzoic acids and flavonoids. Gastrointestinal digestion of GERM, SPD, and MEC revealed high stability of total phenolic compounds in both gastric and intestinal phases. Hydroxycinnamic acids were the most bioaccessible compounds during digestion among the three bioprocessed wheat ingredients studied, although their bioaccessibility varied across ingredients. In this sense, the bioaccessibility of ferulic acid (FA) derivatives increased in GERM with progression of the digestion, while it was reduced in SPD and MEC up to the end of the intestinal phase. Microencapsulation of SPD with pea protein led to generally to lower bioaccessible amounts of phenolic acids. Comparison analysis of biological effects highlighted SPD for its most potent antioxidant effects in the gastrointestinal tract (3 out 4 antioxidant parameters with highest values), while no clear differences were observed with regard to in vitro anti-inflammatory activity. Overall, these results support the potential application of GERM, SPD, and MEC as functional and nutraceutical ingredients.

Abstract
Tuberculosis (TB) remains a worldwide public health threat because of the emergence of resistant strains and subsequent inappropriate response to current therapy. We have been studying the restinga plants' antimycobacterial and anti-inflammatory potential. Dichloromethane fraction (DCM) from Vitex polygama Cham. showed high activity against Mycobacterium tuberculosis (Mtb) H37Rv. In this context, DCM fraction and isolated compounds were investigated against Mtb H37Rv and M299 (MDR strain) and for their immunomodulatory and cytotoxicity actions. Orientin showed the best antimycobacterial effect against Mtb M299 MDR strain (MIC50 15.4 ± 1.6 µg/mL), capacity of inhibiting NO production by macrophages (IC50 6.5 ± 1.2 µg/mL) and no significant cytotoxicity. The antimycobacterial effect of orientin was also observed on Mtb H37Rv intracellular growth in RAW 264.7 macrophages (MIC50 3.5 ± 1.1 and MIC90 9.1 ± 1.0 µg/mL). This is the first report describing the antimycobacterial effect of orientin, in both extra- and intracellular growth.

Abstract
The Wnt and Notch signalling pathways are important for maintenance of intestinal epithelial barrier integrity by intestinal stem cells (ISCs). Dysfunction of these pathways is implicated in inflammatory bowel disease (IBD) and colon cancer. The objective of this review is to summarise advancements of drugs that regulate Wnt and Notch in the treatment of IBD and colon cancer. The compositions and biological effects of Wnt and Notch modulators in both ISCs and non-ISCs are discussed. The drugs, including phytochemicals, plant extracts, probiotics and synthetic compounds, have been found to regulate Wnt and Notch signalling pathways by targeting regulatory factors (including secreted frizzled-related proteins or pathway proteins such as β-catenin and γ-secretase) to alleviate IBD and colon cancer. This review highlights the potential for targeting Wnt and Notch pathways to treat IBD and colon cancer.

Abstract
Knowledge on the specific variation in the phenolic composition of wheat defined by germination conditions and its relationship with antioxidant and anti-inflammatory properties of sprouts would be useful to improve the functional value of wheat-derived products. Variation in soluble phenolic composition, antioxidant and anti-inflammatory potential of wheat was examined in a range of germination temperature (12-21 °C) and time (1-7 d). Response surface methodology was applied for building lineal and quadratic models to find optimal germination conditions to improve nutraceutical value of wheat sprouts using the desirability (D) function. Phenolics were determined by HPLC-DAD-ESI-MS. In vitro biochemical methods and lipopolysaccharide stimulated RAW264.7 macrophages were used to determine antiradical and anti-inflammatory activities of wheat sprouts. Accumulation of soluble phenolic acids, flavone C-glycosides and lignans in sprouts was positively influenced by germination temperature and time. Increased concentration of individual polyphenols was directly associated with improved ability of sprouts for radical scavenging and reduction of tumor necrosis factor α and interleukin 6 in macrophages. Optimal desirability (D = 0.89) for improved nutraceutical value of wheat sprouts was achieved at 21 °C for 7 d. This information would be useful for food industry aiming at producing wheat-based products with better nutritional and healthy properties.

Abstract
Isoorientin is a natural C-glucosyl flavone that is generating a lot of interest due to its multiple pharmacological activities. Increasing experimental data have shown that the robust antioxidant and anti-inflammatory properties of isoorientin remain important in ameliorating a number of metabolic complications. In fact, plants rich in isoorientin have demonstrated strong ameliorative properties against complications such as hyperglycemia, hyperlipidemia, and insulin resistance. However, while such evidence is accumulating, it has not been reviewed to better inform on the therapeutic potential of this flavone in improving human health. This review examines and extrapolates available literature on the potential beneficial or detrimental effects associated with the use of isoorientin in mitigating metabolic diseases, with a specific focus on diabetes, obesity, and insulin resistance, including associated complications. The discussion includes effective doses in various experimental settings and proposed molecular mechanisms by which isoorientin may exert its therapeutic effects. In addition, the protective effects of extracts of a number of isoorientin-rich plants against metabolic complications will be highlighted.

Abstract
The aerial parts of Tetrastigma hemsleyanum (APTH) have been used as a functional tea in China. The purpose of the current study was to identify the bioactive constituents with inhibitory activity against soluble epoxide hydrolase (sEH) and inducible nitric oxide synthase (iNOS), which are jointly considered potential therapeutic targets for vascular system diseases. In the present study, 39 compounds (1-39) were isolated from the APTH. Among them, compounds 8, 10, 12, 16, 17, 19, and 32 displayed potential activities, with IC50 values ranging from 4.5 to 9.5 µM, respectively, and all in non-competitive inhibition mode. Compounds 5, 10, 12, 19, and 32 displayed potent iNOS inhibitory effects, with IC50 values ranging from 15.6 to 47.3 µM. The results obtained in this work contribute to a better understanding of the pharmacological activities of T. hemsleyanum and its potential application as a functional food.

Abstract
Chronic intestinal inflammation is critical risk factor of colorectal cancer. Triticum aestivum sprouts have been reported to provide a number of health benefits and used as a dietary supplement. In this study, the authors investigated the regulatory effects of T. aestivum sprouts ethanol extract (TAEE) on experimental colorectal carcinogenesis in an azoxymethane (AOM)/dextran sulfate sodium (DSS)-induced mouse model. Oral administration of TAEE significantly attenuated crypt destruction and tumor formation in AOM/DSS-treated mice. Levels of inflammatory mediators involved in colorectal carcinogenesis, that is, tumor necrosis factor-α, interkeukin (IL)-1β, IL-6, cyclooxygenase-2, and inducible nitric oxide synthase, were lower in the colons of 200 mg/kg TAEE-treated mice than in AOM/DSS controls (p < 0.05). Immunohistochemical staining showed that levels of nuclear factor-kappa B p65 and β-catenin were attenuated by TAEE in the colon tissues of AOM/DSS-treated mice. Furthermore, levels of β-catenin-related genes (cyclin D1 and c-Myc), which are known to contribute to cell cycle regulation, were decreased in the colon tissues of TAEE-treated mice versus AOM/DSS controls (p < 0.01). These results showed TAEE inhibited colon inflammation and neoplasm formation caused by AOM/DSS treatment, suggesting that TAEE could be useful for the prevention and treatment of colitis-associated colon cancer.

Abstract
Triticum aestivum sprout-derived polysaccharide (TASP) has anti-diabetic properties, but no information is available in regards to its protective effect against ethanol-induced hepatic injury. This study aimed to investigate the mechanism behind the protective role of TASP against ethanol-induced liver injury in vivo. Male C57BL/6 mice were administered ethanol with or without TASP for 10 consecutive days by oral gavage. Silymarin was administered in the same manner as a positive control. TASP reduced ethanol-induced hepatic lipid accumulation and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. TASP also prevented glutathione (GSH) depletion and increased the superoxide dismutase (SOD) in liver tissue. In addition, TASP significantly inhibited ethanol-induced cytochrome P450 2E1 (CYP2E1) activation, and upregulated the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1), and downregulated NADPH oxidase genes in ethanol fed mice. Furthermore, the upregulation of Nrf2 was found to be regulated by a phosphatidylinositol 3-kinase (PI3K)/Akt pathway. TASP also attenuated hepatic injury by modulation of caspase-3 and apoptosis-associated mitochondrial proteins including B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) in liver tissues of mice. The study demonstrated that TASP treatment protects against ethanol-induced hepatic injury via multiple pathways by inhibiting steatosis and improving antioxidant marker levels during hepatic injury. Such properties provide a basis for therapeutic agents against alcohol-induced liver injury.

A dichloromethane fraction of Triticum aestivum sprouts reduces allergic immune response through inhibiting Th2 differentiation in ovalbumin‑immunized mice. Mol Med Rep 2017; 16:3535-3541.

Abstract
Triticum aestivum sprouts are small shoots that germinate from seeds and are consumed as a dietary supplement. The present study aimed to determine whether a dichloromethane fraction isolated from Triticum aestivum sprouts (TDF) suppressed the allergic immune response in ovalbumin (OVA)‑sensitized mice. In vivo experiments were performed by administering TDF or vehicle to mice during the sensitization and this was immediately followed by an intradermal injection of OVA into the ears. Splenocytes isolated from OVA‑sensitized mice were pre‑treated with TDF and re‑challenged with OVA for ex vivo evaluation. Results demonstrated that TDF suppressed the inflammatory response in ear tissues and levels of total immunoglobulin (Ig)E and OVA‑specific IgE in serum. TDF inhibited the production of interleukin (IL)‑4 and expression of GATA‑binding protein‑3 (GATA‑3) transcription factor which regulates the differentiation of naïve T helper (Th) cells into Th2 cells in OVA‑stimulated splenocytes. TDF inhibited Th1‑associated cytokine interferon‑γ and IL‑12 production and downregulated the expression of Th1 specific transcription factor T‑box 21 in OVA‑stimulated splenocytes. Overall, these results indicated that TDF attenuates OVA‑induced allergic immune response by suppressing the production of Th2 specific cytokine IL‑4, through inhibiting transcription factor GATA‑3, and suggests that TDF may exhibit the potential to regulate the immune response in allergic diseases.

Abstract
Accumulated evidence in epidemiological studies has consistently shown that consumption of whole grains (WGs) is inversely associated with risk of major chronic diseases such as certain types of cancer, type 2 diabetes, and cardiovascular diseases. Dietary fiber (DF) has been reported to be responsible for the health effects of WG consumption. Evidence from in vitro and in vivo studies is emerging that, in addition to DF and minerals, the unique phytochemicals in WGs may in part contribute to these health-promoting effects. WGs are rich sources of various phytochemicals. However, phytochemical contents and profiles in WG wheat are not systematically summarized yet, and the rapid rate of discovery of wheat phytochemicals necessitates an update on the current state of this field. Furthermore, the biological roles of phytochemicals in protective effects of WGs are also relatively underestimated compared to DFs. This manuscript summarized current research literature regarding phytochemicals that have been identified and characterized from wheat grains and wheat bran, and their corresponding contributions to the major health benefits of WG wheat consumption.

Abstract
Non-small cell lung cancer (NSCLC) is the major cancer-related death worldwide with only 14% five-year survival rate. Triticumoside, a phenolic compound present in Triticum aestivum sprout extract, has been recognized to have antiobesity and anti-inflammatory effects. However, the effect of triticumoside on cancer cell proliferation and migration has not been studied. In order to elucidate whether triticumoside exhibits an anticancer effect, cells were incubated with different doses of triticumoside, and apoptosis was assessed by observing cell viability, cellular morphological changes, and annexin-V-fluorescein isothiocyanate/propidium iodide staining. Cell cycle analysis, western blotting, wound healing assay, and quantitative-polymerase chain reaction were also performed. Triticumoside exhibited marked cytotoxicity in the cells in dose- and time-dependent manner. Triticumoside caused morphological changes, including cellular rounding, nuclear condensation, and shrinkage. Likewise, triticumoside enhanced the sub-G1 proportion of cells. Additionally, triticumoside regulated expression of apoptosis-associated proteins, such as B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X, and procaspase-3/9. Triticumoside also inhibited migration of the cells through downregulation of matrix metalloproteinase-2/9 (MMP2/9). Collectively, these results suggest that triticumoside induces apoptosis through caspase-dependent mitochondrial pathway and suppresses migration via inhibition of MMP2/9 in NSCLC A549 cells.
