[PMID: 39072786 DOI: 10.1111/1750-3841.17174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Revised: 05/14/2024] [Accepted: 05/29/2024] [Indexed: 07/30/2024]
Abstract
Hyperlipidemia has been suggested to be associated with dysregulation of lipid metabolism and gut microbiota. The present study prepared microencapsulated rice bran (MRB) with high stability based on in situ rice bran oil embedding and investigated the effects of MRB on lipid metabolism and gut microbiota in hyperlipidemic mice induced by high-fat diet (HFD). Results showed that compared to HFD fed mice, lipid levels in serum and hepatic lipid accumulation were reduced in mice fed with MRB, which was potentially associated with the fact that MRB decreased the expression of genes related to lipogenesis (Srebp1c, Acc, Hmgcr, and Fas) and increased the expression of genes related to lipid catabolism (Hsl, Atgl) and oxidation (Acox, Cpt1, Ucp1) (p < 0.05). In gut, MRB supplementation significantly elevated the abundance of beneficial bacteria, such as Dubosiella and Faecalibaculum. In addition, significant increase in short-chain fatty acid was observed in mice from MRB groups when compared to HFD groups (p < 0.05). Overall, this study suggested that MRB could alleviate the hyperlipidemia induced by HFD, which was related to the alteration of lipid metabolism and gut microbiota.

Abstract
Skeletal muscle (SkM) is a plastic and dynamic tissue, essential in energy metabolism. Growing evidence suggests a close relationship between intramuscular fat accumulation, oxidative stress (OS), extracellular matrix (ECM) remodeling, and metabolic deregulation in SkM. Nowadays natural products emerge as promising alternatives for the treatment of metabolic disorders. We have previously shown that chia seed administration reverts SkM lipotoxicity and whole-body insulin resistant (IR) in sucrose-rich diet (SRD) fed rats. The purpose of the present study was to assess the involvement of OS and fibrosis in SkM metabolic impairment of insulin-resistant rats fed a long-term SRD and the effects of chia seed upon these mechanisms as therapeutic strategy. Results showed that insulin-resistant SRD-fed rats exhibited sarcopenia, increase in lipid peroxidation, altered redox state, and ECM remodeling-increased collagen deposition and lower activity of the metalloproteinase 2 (MMP-2) in SkM. Chia seed increased ferric ion reducing antioxidant power and glutathione reduced form levels, and the activities of glutathione peroxidase and glutathione reductase enzymes. Moreover, chia seed reversed fibrosis and restored the MMP-2 activity. This work reveals a participation of the OS and ECM remodeling in the metabolic alterations of SkM in our experimental model. Moreover, current data show novel properties of chia seed with the potential to attenuate SkM OS and fibrosis, hallmark of insulin-resistant muscle.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:3352-3360. [PMID: 38105416 DOI: 10.1002/jsfa.13220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 11/17/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Omega-3 fatty acids are known for their various health benefits. Chia is the richest vegetable source of omega-3 fatty acids. However, its oil is highly susceptible to oxidative deterioration and should be protected for incorporation into food matrices. This work aimed to study the incorporation of different chia oil microcapsules in a powdered beverage, analyzing the effect on the physicochemical characteristics and stability during storage. RESULTS Different types of microcapsules were obtained: monolayer microcapsules using sodium caseinate and lactose as wall material, and multilayer microcapsules produced through electrostatic deposition using lecithins, chitosan, and chia mucilage as the first, second, and third layers, respectively. The results demonstrated an efficient enrichment of smoothies, with omega-3 fatty acid values ranging from 24.09% to 42.73%, while the original food matrix powder lacked this component. These powder beverages exhibited low moisture content (≤ 2.91%) and low water activity (≤ 0.39). The aerated, packed density and compressibility assays indicated that adding microcapsules made the powders less dense and compressible. The color of the original powdered beverage was not modified. The dispersibility reflected an acceptable instantaneity, reaching the maximum obscuration after 30 s of stirring. The solubility of all the enriched products was higher than 70%, whereas the pH was ~6.8. The contact angle between the powder and liquid indicated an excellent ability to be reconstituted in water. The analysis of the glass transition temperature showed that the storage temperature (25 °C) was adequate. The peroxide value of all the products was low throughout the storage (≤ 1.63 meq peroxide kg-1 of oil at 90 days at 25 ± 2 °C), thus maintaining the quality of the microencapsulated chia oil. CONCLUSIONS The results suggest that incorporating the monolayer and multilayer chia oil microcapsules that were studied could be a viable strategy for enriching smoothies with the omega-3 fatty acids present in chia seed oil. © 2023 Society of Chemical Industry.

Nutritional Potential of Adzuki Bean Germplasm and Mining Nutri-Dense Accessions through Multivariate Analysis. Foods 2023; 12:4159. [PMID: 38002217 PMCID: PMC10670495 DOI: 10.3390/foods12224159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 10/30/2023] [Accepted: 11/11/2023] [Indexed: 11/26/2023] Open
Abstract
The adzuki bean (Vigna angularis), known for its rich nutritional composition, holds significant promise in addressing food and nutritional security, particularly for low socioeconomic classes and the predominantly vegetarian and vegan populations worldwide. In this study, we assessed a total of 100 diverse adzuki bean accessions, analyzing essential nutritional compounds using AOAC's official analysis procedures and other widely accepted standard techniques. Our analysis of variance revealed significant genotype variations for all the traits studied. The variability range among different traits was as follows: moisture: 7.5-13.3 g/100 g, ash: 1.8-4.2 g/100 g, protein: 18.0-23.9 g/100 g, starch: 31.0-43.9 g/100 g, total soluble sugar: 3.0-8.2 g/100 g, phytic acid: 0.65-1.43 g/100 g, phenol: 0.01-0.59 g/100 g, antioxidant: 11.4-19.7 mg/100 g GAE. Noteworthy accessions included IC341955 and EC15256, exhibiting very high protein content, while IC341957 and IC341955 showed increased antioxidant activity. To understand intertrait relationships, we computed correlation coefficients between the traits. Principal Component Analysis (PCA) revealed that the first four principal components contributed to 63.6% of the variation. Further, hierarchical cluster analysis (HCA) identified nutri-dense accessions, such as IC360533, characterized by high ash (>4.2 g/100 g) and protein (>23.4 g/100 g) content and low phytic acid (0.652 g/100 g). These promising compositions provide practical support for the development of high-value food and feed varieties using effective breeding strategies, ultimately contributing to improved global food security.

Abstract
We investigated the hyperlipidemic effect of different doses of lotus seed resistant starch (low-, medium and high-dose LRS, named as LLRS, MLRS and HLRS, respectively) in hyperlipidemic mice using gut microbiota-metabolic axis compared to high-fat diet mice (model control group, MC). Allobaculum was significantly decreased in LRS groups compared to MC group, while MLRS promoted the abundance of norank_f_Muribaculaceae and norank_f_Erysipelotrichaceae. Moreover, supplementation of LRS promoted cholic acid (CA) production and inhibited deoxycholic acid compared to MC group. Among, LLRS promoted formic acid, MLRS inhibited 20-Carboxy-leukotriene B4, while HLRS promoted 3, 4-Methyleneazelaic acid and inhibited Oleic acid and Malic acid. Finally, MLRS regulate microbiota composition, and this promoted cholesterol catabolism to form CA, which inhibited serum lipid index by gut microbiota-metabolic axis. In conclusion, MLRS can promote CA and inhibit medium chain fatty acids, so as to play the best role in lowering blood lipids in hyperlipidemia mice.

Abstract
Type 2 diabetes mellitus (T2DM) emerged as a major health care concern in modern society, primarily due to lifestyle changes and dietary habits. Obesity-induced insulin resistance is considered as the major pathogenic factor in T2DM. In this study, we investigated the effect of vindoline, an indole alkaloid of Catharanthus roseus on insulin resistance (IR), oxidative stress and inflammatory responses in dexamethasone (IR inducer)-induced dysfunctional 3T3-L1 adipocytes and high-glucose-induced insulin-resistant L6-myoblast cells. Results showed that dexamethasone-induced dysfunctional 3T3-L1 adipocytes treated with different concentrations of vindoline significantly enhanced basal glucose consumption, accompanied by increased expression of GLUT-4, IRS-1 and adiponectin. Similarly, vindoline-treated insulin-resistant L6 myoblasts exhibited significantly enhanced glycogen content accompanied with upregulation of IRS-1 and GLUT-4. Thus, in vitro studies of vindoline in insulin resistant skeleton muscle and dysfunctional adipocytes confirmed that vindoline treatment significantly mitigated insulin resistance in myotubes and improved functional status of adipocytes. These results demonstrated that vindoline has the potential to be used as a therapeutic agent to ameliorate obesity-induced T2DM-associated insulin resistance profile in adipocytes and skeletal muscles.

Abstract
Numerous plants, plant extracts, and plant-derived compounds are being explored for their beneficial effects against overweight and liver diseases. Obesity is associated with the increased prevalence of non-alcoholic fatty liver disease (NAFLD), becoming the most common liver disease in Western countries. Obesity and NAFLD are closely associated with many other metabolic alternations such as insulin resistance, diabetes mellitus, and cardiovascular diseases. Many herbs of the Lamiaceae family are widely employed as food and spices in the Mediterranean area, but also in folk medicine, and their use for the management of metabolic disorders is well documented. Hereby, we summarized the scientific results of the medicinal and nutraceutical potential of plants from the Lamiaceae family for prevention and mitigation of overweight and fatty liver. The evidence indicates that Lamiaceae plants may be a cost-effective source of nutraceuticals and/or phytochemicals to be used in the management of metabolic-related conditions such as obesity and NAFLD. PubMed, Google Scholar, Scopus, and SciFinder were accessed to collect data on traditional medicinal plants, compounds derived from plants, their reported anti-obesity mechanisms, and therapeutic targets.

Abstract
Given obesity and its associated metabolic disorders have reached epidemic proportions, the study of therapeutic strategies targeting white adipose tissue (WAT) are of main research interest. We previously shown that α-linolenic acid-rich chia seed was able to ameliorate a wide range of metabolic disorders including body fat accretion in sucrose-rich diet (SRD)-fed rats, an experimental model of visceral adiposity and insulin resistance. However, the mechanisms involved are not fully clarified. The aim of this study was to evaluate the effect of chia seed administration upon WAT remodeling and key enzymes that controls lipolysis, insulin signaling (tAKT, pAKT), and GLUT-4 levels in different visceral fat pad depots (epididymal -eWAT- and retroperitoneal -rWAT- adipose tissues) of SRD-fed rats. Results showed that chia seed reduces adipocytes hypertrophy, the increased lipid content and collagen deposition in both WAT. These changes were accompanied by a significant reduction of HSL and ATGL protein levels in eWAT and HSL protein levels in rWAT. Moreover, chia seed restored the altered expression pattern of the pAKT observed in SRD-fed rats, and modulated GLUT-4 levels. Chia seed could be a dietary intervention of great relevance with potential beneficial effects in the management of body fat excess and WAT function.

Abstract
Introduction Background: adipose tissue dysfunction is a key factor for diabetes and non-alcoholic fatty liver disease (NAFLD) development. Chia (Salvia hispanica) is an abundant source of omega-3 fatty acids, antioxidants, and fiber which could improve adipose tissue functionality. Aim: to analyze the effect of an isocaloric chia-supplemented diet on glucose metabolism, adipose tissue inflammation, and endothelial function markers in patients with NAFLD and early stages of diabetes. Methods: in 32 patients with previous NAFLD diagnosis, without known diabetes, the effect of a diet supplemented with ground chia (25 g/day/8 weeks) was evaluated. Visceral (VAF) and liver fat, plasma lipids, fatty acids, and cytokine profiles, oral glucose tolerance test (OGTT), insulinogenic index (IGI30), insulin disposition index (DIO), and endothelial progenitor cells (EPC) were analyzed. Before and after eight weeks of diet supplementation. Results: chia supplementation promoted increases in plasma alpha-linolenic acid (75 %) and fiber consumption (55 %), and a higher number of EPC (+126 %). Basal OGTT showed that nine patients had normal OGTT, 17 pre-diabetes, and six newly diagnosed diabetes. In patients with diabetes, chia favored a healthier adipose tissue (VAF -7 %, NAFLD -100 %, adiponectin +47 %, resistin -30 %, IL-6 -44 %, IL-1β -22 %) and upturn glucose metabolism through the improvement of beta-cell function (IGI30 +50 %, DIO +66 %). Conclusions: dietary supplementation with 25 g/day of ground chia may promote a healthier adipose tissue and improve pancreatic β-cell and endothelial function. Among patients with early metabolic abnormalities, phytochemical properties of chia may retard diabetes progression and advanced stages of liver damage.

Abstract
The aim of this study was to analyze blood coagulation, endothelial dysfunction and liver fibrosis in an experimental model of Metabolic Syndrome (MS) induced by chronic administration of a sucrose-rich diet (SRD) and to evaluate the effects of chia seed as a therapeutic strategy. Male Wistar rats were fed with a reference diet (RD) - 6 months - or a SRD - 3 months. Then, the last group was randomly divided into two subgroups. One subgroup continued receiving the SRD for up to 6 months and the other was fed with a SRD where whole chia seed was incorporated as the source of dietary fat for the next 3 months (SRD + CHIA). Results showed that rats fed a SRD for a long period of time develop dyslipidemia, visceral adiposity, insulin resistance, and a hypercoagulable and hypofibrinolytic basal state. Hepatic VCAM-1 (main adhesion molecules involved in endothelial dysfunction) expression was significantly increased. In addition, the SRD group presented hepatic steatosis, a significant increase in interstitial collagen deposition and hydroxyproline content. Liver TGF-β1 (a key cytokine involved in fibrogenesis) levels increased and a negative correlation with PPARα protein mass levels was found. The administration of chia seed for 3 months reversed dyslipidemia, visceral adiposity and insulin resistance. Platelet count, coagulation parameters and plasma fibrinogen levels were normalized. In the liver tissue, VCAM-1 expression, steatosis, interstitial collagen deposition and the hydroxyproline content decreased. TGF-β1 expression was decreased and this was associated with an increase in the PPARα protein levels. The present study showed new aspects in the progression from liver steatosis to fibrosis in dyslipidemic insulin-resistant rats chronically fed a sucrose-rich diet. Chia seed supplementation could be used as a functional food and a potential dietary strategy to prevent or ameliorate disorders related to atherothrombotic cardiovascular events and NASH.

Assessment of the Phytochemical and Nutrimental Composition of Dark Chia Seed ( Salvia hispánica L.). Foods 2021; 10:3001. [PMID: 34945556 PMCID: PMC8702123 DOI: 10.3390/foods10123001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 11/24/2021] [Accepted: 11/26/2021] [Indexed: 11/17/2022] Open
Abstract
Chia seeds are rich sources of different macro and micronutrients associated with health benefits; thus, they may be considered as a functional food. However, the composition depends on the variety, origin, climate and soil. Here, we show a comprehensive characterization of extractable and non-extractable phenolic compounds of dark chia seed Salvia hispanica L. using high-performance liquid chromatography-electrospray ionization-quadrupole time-of-flight (HPLC-ESI-QTOF) and discuss potential health benefits associated with the presence of a number of nutritional and bioactive compounds. We report that dark chia from Jalisco is a high-fiber food, containing omega-3 polyunsaturated fatty acids, essential amino acids (phenylalanine and tryptophan), and nucleosides (adenosine, guanidine and uridine), and rich in antioxidant phenolic compounds, mainly caffeic acid metabolites. Our data suggest that chia seeds may be used as ingredients for the development of functional foods and dietary supplements.

Chia oil prevents chemical and immune-mediated inflammatory responses in mice: Evidence for the underlying mechanisms. Food Res Int 2021; 149:110703. [PMID: 34600695 DOI: 10.1016/j.foodres.2021.110703] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 08/31/2021] [Accepted: 09/02/2021] [Indexed: 10/20/2022]
Abstract
Chia (Salvia hispanica L.) is an herbaceous plant used as omega-3 polyunsaturated fatty acid (ω-3 PUFA) source that presents a range of beneficial effects on human health. Herein, it was used a chia oil containing over than 62% of α-linolenic acid (ALA), a compound widely related to anti-inflammatory actions. Chia oil effect was tested using paw edema and mechanical hyperalgesia induced by carrageenan, and ear edema induced by croton oil, histamine, and capsaicin. Croton oil was used in both preventive and therapeutic treatment schedules of chia oil while histamine and capsaicin were used only in preventive treatment schedule. Chia oil mechanism of action was investigated using nociception and paw edema response induced by intraplantar injection of acidified saline (ASIC activator), PGE2 (prostaglandin pathway), cinnamaldehyde (TRPA1 activator), bradykinin (BK pathway), menthol (TRPM8 activator), and capsaicin (TRPV1 activator). Further, RT-PCR for inflammatory mediators (TRPA1, NF-κB, PPAR-γ, COX-2, IL-6, TNF, FPR2, FAAH, MAGL, and IL-12A) induced by carrageenan, NLRP3 inflammasome activation, and the cell viability were then accessed. Later, chia oil actions were evaluated in the experimental autoimmune encephalomyelitis (EAE), a multiple sclerosis (MS) model. Chia oil showed anti-edematogenic and anti-hyperalgesic effects when administered 1 h before pro-inflammatory stimulus - particularly carrageenan and croton oil. Moreover, chia oil upregulated the mRNA levels of COX-2 and formyl peptide receptor 2 (FPR2) while reduced IL-6 expression in the spinal cord of mice submitted to i.pl. injection of carrageenan. Interestingly, chia oil mediates antinociceptive effects in mice decreasing the nociceptive response induced by acidified saline, PGE2, and cinnamaldehyde, but not by bradykinin, menthol, and capsaicin. On the EAE model, chia oil preventively administered attenuated EAE-induced motor deficits and mechanical hyperalgesia in mice, suggesting a valuable effect of chia oil supplementation in regulating inflammatory responses and some immune functions during immune-mediated inflammatory disorders (IMID). Nonetheless, additional reports will need to assess the effect of chia oil in well-controlled clinical trials performed in MS patients.

Abstract
α-linolenic acid (ALA, 18:3n-3) is a carboxylic acid composed of 18 carbon atoms and three cis double bonds, and is an essential fatty acid indispensable to the human body. This study aims to systematically review related studies on the dietary sources, metabolism, and pharmacological effects of ALA. Information on ALA was collected from the internet database PubMed, Elsevier, ResearchGate, Web of Science, Wiley Online Library, and Europe PMC using a combination of keywords including "pharmacology," "metabolism," "sources." The following findings are mainly contained. (a) ALA can only be ingested from food and then converted into eicosapentaenoic acid and docosahexaenoic acid in the body. (b) This conversion process is relatively limited and affected by many factors such as dose, gender, and disease. (c) Pharmacological research shows that ALA has the anti-metabolic syndrome, anticancer, antiinflammatory, anti-oxidant, anti-obesity, neuroprotection, and regulation of the intestinal flora properties. (d) There are the most studies that prove ALA has anti-metabolic syndrome effects, including experimental studies and clinical trials. (e) The therapeutic effect of ALA will be affected by the dosage. In short, ALA is expected to treat many diseases, but further high quality studies are needed to firmly establish the clinical efficacy of ALA.

Abstract
Adipose tissue is instrumental in maintaining metabolic homeostasis by regulating energy storage in the form of triglycerides. In the case of over-nutrition, adipocytes favorably regulate lipogenesis over lipolysis and accumulate excess triglycerides, resulting in increased adipose tissue mass. An abnormal increase in hypertrophic adipocytes is associated with chronic complications such as insulin resistance, obesity, diabetes, atherosclerosis and nonalcoholic fatty liver disease. Experimental studies indicate the occurrence of oxidative stress in the pathogenesis of obesity. A common underlying link between increasing adipose tissue mass and oxidative stress is the Nuclear Factor Erythroid 2-related factor 2 (Nrf2), Keap1-Nrf2-ARE signaling, which plays an indispensable role in metabolic homeostasis by regulating oxidative and inflammatory responses. Additionally, Nrf2 also activates CCAAT/enhancer-binding protein α, (C/EBP-α), C/EBP-β and peroxisome proliferator-activated receptor γ (PPARγ) the crucial pro-adipogenic factors that promote de novo adipogenesis. Hence, at the forefront of research is the quest for prospecting novel compounds to modulate Nrf2 activity in the context of adipogenesis and obesity. This review summarizes the molecular mechanism behind the activation of the Keap1-Nrf2-ARE signaling network and the role of Nrf2 activators in adipocyte pathophysiology.

Abstract
Chia (Salvia hispanica L.), now a popular superfood and a pseudocereal, is one of the richest sources of dietary nutrients such as protein, fiber, and polyunsaturated fatty acids (PUFAs). At present, the genomic and genetic information available in the public domain for this crop are scanty, which hinders an understanding of its growth and development and genetic improvement. We report an RNA-sequencing (RNA-Seq)-based comprehensive transcriptome atlas of Chia sampled from 13 tissue types covering vegetative and reproductive growth stages. We used ~355 million high-quality reads of total ~394 million raw reads from transcriptome sequencing to generate de novo reference transcriptome assembly and the tissue-specific transcript assemblies. After the quality assessment of the merged assemblies and implementing redundancy reduction methods, 82,663 reference transcripts were identified. About 65,587 of 82,663 transcripts were translated into 99,307 peptides, and we were successful in assigning InterPro annotations to 45,209 peptides and gene ontology (GO) terms to 32,638 peptides. The assembled transcriptome is estimated to have the complete sequence information for ~86% of the genes found in the Chia genome. Furthermore, the analysis of 53,200 differentially expressed transcripts (DETs) revealed their distinct expression patterns in Chia's vegetative and reproductive tissues; tissue-specific networks and developmental stage-specific networks of transcription factors (TFs); and the regulation of the expression of enzyme-coding genes associated with important metabolic pathways. In addition, we identified 2,411 simple sequence repeats (SSRs) as potential genetic markers from the transcripts. Overall, this study provides a comprehensive transcriptome atlas, and SSRs, contributing to building essential genomic resources to support basic research, genome annotation, functional genomics, and molecular breeding of Chia.

Abstract
The aim of this study was to analyze the effects of Salvia hispanica L. (chia) seed upon metabolic pathways that play a key role in adipose tissue lipid handling which could be involved in visceral adiposity reduction developed in rats fed a sucrose-rich diet (SRD). Male Wistar rats were fed with a reference diet (RD) -6 months- or SRD-3 months. Then, the last group was randomly divided into two subgroups. One subgroup continued receiving the SRD up to 6 months and the other was fed with a SRD where whole chia seed was incorporated as the source of dietary fat for the next 3 months (SRD + CHIA). Results showed that chia seed in the SRD-fed rat reduced the abdominal and thoracic circumferences, carcass fat content, adipose tissue weights, and visceral adiposity index. This was accompanied by an improvement in insulin sensitivity and plasma lipid profile. In epididymal adipose tissue, the decreased fat cell triglyceride content was associated with a reduction in both, FAT/CD 36 plasma membrane levels and the fat synthesis enzyme activities. There were not changes in oxidative CPT enzyme activities. PKCβ and the precursor and mature forms of SREBP-1 protein levels were decreased, while pAMPK was increased. Our findings suggest that chia seed supplementation can modulate essential pathways of lipid metabolism in adipose tissue, contributing to reduced visceral fat accumulation in SRD-fed rats.

Abstract
Rabbit, nutria and chinchilla testes were evaluated to compare testicular cellular senescence. There were no major species-specific differences in structure of either seminiferous tubules or interstitial tissue. There, however, were occasional abnormalities in seminiferous tubule structure with there being multinucleated and exfoliated cells present in rabbit testes. Furthermore, there were seminiferous tubules without a lumen that were filled with premeiotic/meiotic cells in nutria; and tubules with vacuolization with there being no post-meiotic cells in chinchillas. There were no differences in distribution or content of acids, total proteins and polysaccharides in the testis of any of the three species. Results using comparative immunohistochemistry procedures indicated the testes contained a few senescent cells in seminiferous tubules with typical morphology and there was a large number of senescent cells in seminiferous tubules of nutrias and chinchillas that had an abnormal structure (P <0.001). Compared to rabbit testes, in which there was the least number of senescent cells in seminiferous tubules, there was a greater abundance of senescence markers in both nutria and chinchilla testes (P < 0.05; P < 0.001, respectively). Furthermore, there were small abundances of caspase 3 and LC3 in the testes of all species. In chinchilla testes, there was a lesser concentration of cholesterol (P < 0.001) and testosterone compared with the other species. Cellular senescence in testes, therefore, can be assessed by detection of morpho-functional disorders of the testis of the three species evaluated in the present study.

Abstract
BACKGROUND Skeletal abnormalities such as bone loss occur when there is an imbalance in bone matrix synthesis and bone resorption. This imbalance is also caused by hormonal changes and inflammation. Chia (Salvia hispanica L.) has a high nutritional value and is an excellent source of calcium. Evaluate the bioavailability of calcium from chia, and its effect on bone metabolism when consumed as part of a standard or high fat diet (HFD) in ovariectomized rats. METHODS The study was conducted with 80 female Wistar rats that received standard diet or HFD. 40 female mice were ovariectomized (OVX) and 40 were sham-operated (SHAM). After recovery from surgery the animals received chia as a source of 20% of the calcium recommendation, calcium bioavailability was measured using the calcium balance technique. Bone strength and bone morphometry were evaluated by weight, length and microtomography measurements. RESULTS HFD increased serum calcium and decreased calcium retention. The addition of chia to HFD did not alter bone morphology. Ovariectomy led to lower percentage of bone volume, smaller trabecular thickness, higher trabecular separation and higher porosity, when ovariectomy was associated with HFD, the final weight, waist circumference, body mass index and adiposity were increased. CONCLUSIONS Chia maintained bone health when offered as a source of 20% calcium, in a diet that met 100% of the mineral recommendation, regardless of the type of diet, in animals non-ovariectomized adults.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is a public health problem lacking an approved pharmacological treatment. Omega-3 fatty acids have shown to reverse NAFLD. Chia is a seed rich in α-linolenic acid (ALA), antioxidants, and fiber; therefore, it could be useful to treat NAFLD. Methods In a single arm experimental design study, the effect of 25 g/day of milled chia was assessed in 25 patients with NAFLD. After two weeks of dietary stabilization (basal condition) and eight weeks of a chia-supplemented isocaloric diet, liver:spleen attenuation index and visceral abdominal fat (VAF) were measured by computed tomography. Lipids, lipoproteins, free fatty acids (FFA), and ALA plasma concentrations were also determined. Results Dietary chia supplementation induced an increase in plasma ALA concentration (75%) and dietary fiber (55%) consumption. After chia supplementation, VAF (9%), body weight (1.4%), total cholesterol (2.5%), non-high density lipoprotein cholesterol (3.2%), and circulating FFA (8%) decreased. Furthermore, NAFLD regressed in 52% of the treated patients (P < 0.05 for all). Conclusions The results of the present study show that 25 g/day of milled chia ameliorates NAFLD. Chia is an accessible vegetal source of omega-3 fatty acids, antioxidants, and fiber, which could have the potential to prevent metabolic abnormalities in NAFLD patients. Considering that there is no pharmacological treatment approved for NAFLD, the findings of the present study suggest that a chia-supplemented diet could be an innovative alternative to control this disease.

Abstract
The aim of this review was to compile evidence and understand chia seed effects on unbalanced diet animal studies and the molecular mechanisms on metabolic biomarker modulation. A systematic review was conducted in electronic databases, following PRISMA recommendations. Risk of bias and quality was assessed using SYRCLE toll and ARRIVE guidelines. Seventeen articles were included. Throughout the studies, chia's main effects are associated with AMPK modulation: improvement of glucose and insulin tolerance, lipogenesis, antioxidant activity, and inflammation. Details about randomization and allocation concealment were insufficient, as well as information about blind protocols. Sample size, chia dose, and number of animals evaluated for each parameter were found to be lacking information among the studies. Based on experimental study data, chia has bioactive potential, and its daily consumption may reduce the risk of chronic disease development, mainly due to the antioxidant, anti-inflammatory, hypoglycemic, and hypolipidemic effects of the seed. PRACTICAL APPLICATION: The consumption of chia seeds may improve lipid profile, insulin and glucose tolerance, and reduce risk of cardiovascular disease. Whole seed or its oil presents positive effect, but the effects of chia oil can act faster than the seed.

Effects of Lactobacillus plantarum PMO 08 Alone and Combined with Chia Seeds on Metabolic Syndrome and Parameters Related to Gut Health in High-Fat Diet-Induced Obese Mice. J Med Food 2019; 22:1199-1207.

Abstract
This study researched the effects of Lactobacillus plantarum PMO 08 alone and combined with chia seeds on metabolic syndrome and parameters related to microbiota modulation and intestinal barrier integrity in obese mice fed high-fat diets (HFDs; 45% kcal fat). Male C57BL/6J mice were acclimated for a period of 2 weeks and then randomly separated into five groups depending on whether they received a normal diet (ND group), an HFD (HFD group), an HFD with L. plantarum (PMO group), an HFD with L. plantarum combined with chia seeds (PMOChia group), or an HFD with chia seeds (Chia group). Serum lipid profiles and related markers (cholesterol metabolism-related gene expression) were measured. Intestinal barrier integrity was assessed by measuring occludin mRNA expression of tight junction proteins. Mucosal bacteria were checked with quantitative reverse transcript polymerase chain reaction (qRT-PCR). After 16 weeks of feeding, the PMO group showed significantly lower serum total cholesterol, low-density lipoprotein cholesterol levels, atherogenic index, and cardiac risk factors compared to the HFD group. Moreover, the hepatic mRNA expression of SREBP2 (sterol regulatory element binding protein 2), a protein related to cholesterol metabolism, was significantly downregulated in the PMO group. We also found a positive synergistic effect in the PMOChia group, as manifested by the hepatic mRNA expression of hepatic CYP7A1 (cholesterol 7α-hydroxylase), strengthening of the gut barrier function, and the promotion of more L. plantarum in the colonic mucosa than in either the HFD or PMO group. In conclusion, our results indicate that PMO 08 may protect against metabolic syndrome by exerting effects on the regulation of lipid metabolism. Although the effects of chia seeds alone remain uncertain based on this experiment, its combination with PMO 08 was demonstrated to improve multiple beneficial effects of PMO 08 in obese mice fed HFD, which is a promising possibility for future research.

Fernández-Martínez E, Lira-Islas IG, Cariño-Cortés R, Soria-Jasso LE, Pérez-Hernández E, Pérez-Hernández N. Dietary chia seeds (Salvia hispanica) improve acute dyslipidemia and steatohepatitis in rats. J Food Biochem 2019; 43:e12986. [PMID: 31489674 DOI: 10.1111/jfbc.12986] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 06/27/2019] [Accepted: 06/30/2019] [Indexed: 02/06/2023]
Abstract
Chia seeds (Salvia hispanica L.) are rich in omega fatty acids. Dyslipidemia and steatohepatitis are diseases that require effective treatments in obese and non-obese patients. The aim was to evaluate the effect of chia intake on acute tyloxapol (TI)-induced dyslipidemia, on acute carbon tetrachloride (TC)-induced steatohepatitis, and on mixed damage (TC+TI) in non-obese rats. Four experimental groups were fed for 4 weeks a diet with established rodent food (DE), and four groups were fed a diet with 15% added chia (DC). Plasma samples were analyzed for total cholesterol, triglycerides, glucose, biochemical liver damage markers, and tumor necrosis factor-α (TNF-α). Liver samples were used to quantify glycogen, catalase, lipid peroxidation, and TNF-α. A histopathological analysis was performed. DC intake partially or totally prevented steatohepatitis, and reduced lipids in the dyslipidemic groups. The hypolipidemic and hepatoprotective effects of chia may be correlated to its high content of α-linolenic acid (omega-3) and phenolics. PRACTICAL APPLICATIONS: Metabolic syndrome is associated with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH), which are currently the most common causes of chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. Dyslipidemia is a significant risk factor for NAFLD and NASH. Non-obese patients may have NAFLD or NASH. Metabolic syndrome and dyslipidemia are more strongly associated with NAFLD in non-obese than in obese patients. This is the first study evaluating the hypolipidemic and hepatoprotective effects of chia seed intake on acute dyslipidemia and/or steatohepatitis caused by the individual or combined administration of the inducers tyloxapol and carbon tetrachloride, respectively, in non-obese rats. The pharmacological effects of dietary chia are correlated to its high content of omega-3 and omega-6 (1:1), protein, dietary fiber, and phenolics. The results suggest that inclusion of chia in diets of non-obese patients with dyslipidemia and/or NAFLD/NASH may improve their health state and preventing cirrhosis or HCC.

Abstract
Obesity is mainly caused by intake of a high-fat diet and sedentarism, and is considered a public health issue worldwide. Increased intestinal permeability may favour endotoxaemia generated by lipopolysaccharides, a substance present in the cell membrane of Gram-negative bacteria, and, consequently, an increase in systemic inflammation and metabolic diseases. In contrast (On the other hand), consumption of a healthy diet can help in the prevention and treatment of metabolic syndrome. In this way, chia seeds (Salvia hispanica L.), rich in polyunsaturated fatty acids, may present an anti-inflammatory role. In addition, chia is rich in antioxidants like caffeic and gallic acid and fiber. However, few studies have investigated the relationship between chia seeds, inflammatory mechanisms and intestinal permeability. Therefore, the aim of this study was to analyse the effects of chia administration on metabolism in obese mice. Swiss mice were fed a hyperlipidic diet either supplemented with or without 3% chia flour for 16 weeks. The results showed that supplementation could not reduce the deleterious effects of the lipid-rich diet in terms of body composition, glucose intolerance and activity of antioxidants enzymes in the liver. In addition, supplementation with chia in the control diet decreased the amount of occludin in the intestinal colon. In conclusion, although chia did not improve metabolic parameters it seemed to restore the intestinal barriers integrity. The beneficial effects of chia seem to be dependent of the quantity used, since our data conflict with those in the literature; however, it is important to note that other studies, unlike our protocol, used chia in the form of seeds or oil, and not flour.

Abstract
This study reports the effects of dietary Salba (chia) seeds on the mechanisms underlying impaired glucose metabolism in the heart of dyslipemic insulin-resistant rats fed a sucrose-rich diet (SRD). Wistar rats were fed a SRD for 3 months. Afterwards, half the animals continued with the SRD; in the other half's diet chia seeds replaced corn oil (CO) for three months (SRD+chia). In the control group, corn starch replaced sucrose. The replacement of CO by chia seeds in the SRD restored the activities of key enzymes involved in heart glucose metabolism decreasing fatty acid oxidation. Chia seeds normalized insulin stimulated GLUT-4 transporter, the abundance of IRS-1 and pAMPK, changed the profile of fatty acid phospholipids, reduced left-ventricle collagen deposition and normalized hypertension and dyslipidemia. New evidence is provided concerning the effects of dietary chia seeds in improving the altered metabolic fate of glucose in the heart of dyslipemic insulin-resistant rats.

Abstract
Background: Studies have demonstrated associations between polyunsaturated fatty acids (PUFAs) and adiposity. It is unclear whether PUFAs in pregnancy have an effect on maternal weight retention after childbirth, which can contribute to long-term obesity.Objective: We examined the association of maternal plasma PUFAs in pregnancy with 18-mo postpartum weight retention (PPWR) in a multiethnic Asian cohort.Design: We studied pregnant women (n = 653) recruited between June 2009 and September 2010 from a prospective cohort. At 26-28 wk of gestation, plasma phosphatidylcholine PUFA concentrations were measured and determined as percentages of total fatty acids (FAs). PPWR was calculated based on the difference between measured weight at the first antenatal clinic visit and at 18 mo postpartum.Results: The median retained weight of women was 0.90 kg (IQR: -1.40, 3.25) at 18 mo postpartum. Of 653 women, 544 women (83.3%) had PPWR of <5 kg and 109 (16.7%) had PPWR of ≥5 kg. In adjusted linear regression models, higher plasma eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and total ω-3 (n-3) PUFA concentrations were associated with lower PPWR [EPA: β = -0.62 kg/1% increase of total FAs (95% CI: -1.18, -0.05); DHA: β = -0.24 kg/1% increase (95% CI: -0.45, -0.02); total ω-3 PUFAs: β = -0.20 kg/1% increase (95% CI: -0.36, -0.03)], whereas a higher ratio of plasma ω-6-to-ω-3 PUFAs was associated with a higher PPWR [β = 0.21 kg/unit increase (95% CI: 0.05, 0.36)].Conclusions: Higher plasma percentages of ω-3 PUFAs and a lower ratio of ω-6-to-ω-3 PUFAs in the late-second trimester of pregnancy are associated with less weight retention at 18 mo postpartum. This may offer an alternative strategy to assist postpartum weight reduction by increasing EPA and DHA status together with a decreased ratio of ω-6-to-ω-3 PUFA through diet or fish-oil supplementation during pregnancy. This study was registered at clinicaltrials.gov as NCT01174875.

Abstract
Chia oil has the highest recognized α-linolenic acid (ALA) content. ALA is associated with beneficial changes in plasma lipids and the prevention of cardiovascular diseases. Present article aims to analyze the effect of Chia oil-enriched restructured pork (RP) on aged rats in a nonalcoholic steatohepatitis (NASH) model. Groups of six male Wistar rats (1-year old) were fed the experimental diets: control RP diet (C) noncholesterol high saturated; cholesterol-enriched high-saturated fat/high-cholesterol control RP diet (HC) with added cholesterol and cholic acid; and Chia oil- or Hydroxytyrosol RP cholesterol-enriched high-saturated fat/high cholesterol (CHIA and HxT). Total cholesterol, hepatosomatic index, Nrf2, antioxidant, and inflammation markers were determined. CHIA reduced the hypercholesterolemic effect by lowering levels similar to C; also, ameliorated redox index. CHIA, despite high polyunsaturated fatty acids (PUFA) content, reduced thiobarbituric acid reactive substances (TBARS) and induced the lowest SOD protein synthesis but not a reduction on its activity. Chia oil activated the Nrf2 to arrest the pro-oxidative response to cholesterol and aging. Endothelial nitric oxide synthase (eNOS) system was lower in HxT than in CHIA, suggesting its antiatherogenic activity and related protective effect against high PUFA. Increase in tumor necrosis factor alpha (TNFα) was partially blocked by CHIA. Chia oil has the ability to prevent oxidative damage and modify the inflammatory response, suggesting adequate regulation of the antioxidant system. Results stress the importance of incorporating ALA into the diet.

Abstract
The present study investigates the benefits of the dietary intake of soy protein on adipose tissue dysfunction in a rat model that mimics several aspects of the human metabolic syndrome. Wistar rats were fed a sucrose-rich diet (SRD) for 4 months. After that, half of the animals continued with SRD until month 8 while in the other half, casein protein was replaced by isolated soy protein for 4 months (SRD-S). A reference group consumed a control diet all the time. In adipose tissue we determined: i) the activities of antioxidant enzymes, gene expression of Mn-superoxide dismutase (SOD) and glutathione peroxidase (GPx), and glutathione redox state ii) the activity of xanthine oxidase (XO), ROS levels and the gene expression of NAD(P)H oxidase iii) the expression of the nuclear factor erythroid-2 related factor-2 (Nrf2). Besides, adiposity visceral index, insulin sensitivity, and tumor necrosis factor-α (TNF-α) in plasma were determined. Compared with the SRD-fed rats, the animals fed a SRD-S showed: activity normalization of SOD and glutathione reductase, improvement of mRNA SOD and normalization of mRNA GPx without changes in the expression of the Nrf2, and improvement of glutathione redox state. These results were accompanied by a normalization of XO activity and improvement of both the ROS production as well as TNF-α levels in plasma. Besides, adipocyte size distribution, adiposity visceral index and insulin sensitivity improved. The results suggest that soy protein can be a complementary nutrient for treating some signs of the metabolic syndrome.

[PMID: 27556399 PMCID: PMC4996530 DOI: 10.1371/journal.pone.0161513] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Accepted: 08/05/2016] [Indexed: 11/24/2022] Open
Abstract
Marine oils are important to human nutrition as the major source of docosahexaenoic acid (DHA), a key omega-3 long-chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) that is low or lacking in terrestrial plant or animal oils. The inclusion of fish oil as main source of n-3 LC-PUFA in aquafeeds is mostly limited by the increasing price and decreasing availability. Fish oil replacement with cheaper terrestrial plant and animal oils has considerably reduced the content of n-3 LC-PUFA in flesh of farmed Atlantic salmon. Novel DHA-enriched oils with high alpha-linolenic acid (ALA) content will be available from transgenic oilseeds plants in the near future as an alternative for dietary fish oil replacement in aquafeeds. As a preliminary validation, we formulated an oil blend (TOFX) with high DHA and ALA content using tuna oil (TO) high in DHA and the flaxseed oil (FX) high in ALA, and assessed its ability to achieve fish oil-like n-3 LC-PUFA tissue composition in Atlantic salmon smolts. We applied proteomics as an exploratory approach to understand the effects of nutritional changes on the fish liver. Comparisons were made between fish fed a fish oil-based diet (FO) and a commercial-like oil blend diet (fish oil + poultry oil, FOPO) over 89 days. Growth and feed efficiency ratio were lower on the TOFX diet. Fish muscle concentration of n-3 LC-PUFA was significantly higher for TOFX than for FOPO fish, but not higher than for FO fish, while retention efficiency of n-3 LC-PUFA was promoted by TOFX relative to FO. Proteomics analysis revealed an oxidative stress response indicative of the main adaptive physiological mechanism in TOFX fish. While specific dietary fatty acid concentrations and balances and antioxidant supplementation may need further attention, the use of an oil with a high content of DHA and ALA can enhance tissue deposition of n-3 LC-PUFA in relation to a commercially used oil blend.

Vegetable oils rich in alpha linolenic acid increment hepatic n-3 LCPUFA, modulating the fatty acid metabolism and antioxidant response in rats. Prostaglandins Leukot Essent Fatty Acids 2016; 111:25-35. [PMID: 26995676 DOI: 10.1016/j.plefa.2016.02.002] [Citation(s) in RCA: 55] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2016] [Revised: 01/28/2016] [Accepted: 02/03/2016] [Indexed: 11/29/2022]
Abstract
Alpha-linolenic acid (C18:3 n-3, ALA) is an essential fatty acid and the metabolic precursor of long-chain polyunsaturated fatty acids (LCPUFA) from the n-3 family with relevant physiological and metabolic roles: eicosapentaenoic acid (C20:5 n-3, EPA) and docosahexaenoic acid (C22:6 n-3, DHA). Western diet lacks of suitable intake of n-3 LCPUFA and there are recommendations to increase the dietary supply of such nutrients. Seed oils rich in ALA such as those from rosa mosqueta (Rosa rubiginosa), sacha inchi (Plukenetia volubis) and chia (Salvia hispanica) may constitute an alternative that merits research. This study evaluated hepatic and epididymal accretion and biosynthesis of n-3 LCPUFA, the activity and expression of Δ-5 and Δ-6 desaturase enzymes, the expression and DNA-binding activity of PPAR-α and SREBP-1c, oxidative stress parameters and the activity of antioxidative enzymes in rats fed sunflower oil (SFO, 1% ALA) as control group, canola oil (CO, 10% ALA), rosa mosqueta oil (RMO, 33% ALA), sacha inchi oil (SIO, 49% ALA) and chia oil (ChO, 64% ALA) as single lipid source. A larger supply of ALA increased the accretion of n-3 LCPUFA, the activity and expression of desaturases, the antioxidative status, the expression and DNA-binding of PPAR-α, the oxidation of fatty acids and the activity of antioxidant enzymes, whereas the expression and DNA-binding activity of SREBP-1c transcription factor and the biosynthetic activity of fatty acids declined. Results showed that oils rich in ALA such as SIO and ChO may trigger metabolic responses in rats such as those produced by n-3 PUFA.

Abstract
Background Recent evidence has demonstrated that the G0/G1 switch gene 2 (G0S2) is an important negative regulator of the rate-limiting lipolytic enzyme adipose triglyceride lipase-mediated lipolysis. It has been revealed that α-linolenic acid (ALA), a plant-based essential omega-3 polyunsaturated fatty acids, reduces adipose tissue lipolysis. However, it is not known whether G0S2 is implicated in ALA-induced inhibition of lipolysis. The purpose of this pilot study is to investigate the effect of ALA on G0S2 gene expression in peripheral blood mononuclear cells (PBMC) of obese patients and the potential influence of G0S2 gene expression in ALA-induced inhibition of lipolysis. Methods A total of 26 obese patients were randomly assigned to be treated with or without ALA treatment (~4.0 g daily) for 12 weeks: the ALA-treated group (n = 14) or the untreated control group (n = 12). Plasma triglyceride (TG), free fatty acids (FFA), glycerol, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), as well as the mRNA expression levels of proliferator-activated receptor gamma (PPAR-γ), G0S2, and G protein-coupled receptor 120 (GPR120) in PBMC were repeatedly examined from fasting obese patients before and after ALA treatment. Results ALA significantly decreased plasma TG, FFA, glycerol, IL-6, and TNF-α levels and increased the mRNA expression levels of PPAR-γ, G0S2, and GPR120 in PBMC, compared with the untreated control group. In obese patients from the ALA-treated group, decreased plasma FFA (a biomarker for lipolysis) level was significantly correlated with increased PPAR-γ (a functional omega-3 fatty acids receptor) and G0S2 (a direct target gene of PPAR-γ) mRNA expression in PBMC, while decreased plasma FFA level was not correlated with increased GPR120 (another functional omega-3 fatty acids receptor) mRNA expression in PBMC. Conclusion This study shows that ALA increases G0S2 gene expression in PBMC in parallel with the decrease of plasma FFA level in obese patients. Increased G0S2 gene expression might contribute to the beneficial anti-lipolytic effect of ALA in obese patients.

Abstract
This study explores the mechanisms underlying the altered lipid metabolism in the heart of dyslipemic insulin-resistant (IR) rats fed a sucrose-rich diet (SRD) and investigates if chia seeds (rich in α-linolenic acid 18:3, n-3 ALA) improve/reverse cardiac lipotoxicity. Wistar rats received an SRD-diet for three months. Half of the animals continued with the SRD up to month 6. The other half was fed an SRD in which the fat source, corn oil (CO), was replaced by chia seeds from month 3 to 6 (SRD+chia). A reference group consumed a control diet (CD) all the time. Triglyceride, long-chain acyl CoA (LC ACoA) and diacylglycerol (DAG) contents, pyruvate dehydrogenase complex (PDHc) and muscle-type carnitine palmitoyltransferase 1 (M-CPT1) activities and protein mass levels of M-CPT1, membrane fatty acid transporter (FAT/CD36), peroxisome proliferator activated receptor α (PPARα) and uncoupling protein 2 (UCP2) were analyzed. Results show that: (a) the hearts of SRD-fed rats display lipotoxicity suggesting impaired myocardial lipid utilization; (b) Compared with the SRD group, dietary chia normalizes blood pressure; reverses/improves heart lipotoxicity, glucose oxidation, the increased protein mass level of FAT/CD36, and the impaired insulin stimulated FAT/CD36 translocation to the plasma membrane. The enhanced M-CPT1 activity is markedly reduced without similar changes in protein mass. PPARα slightly decreases, while the UCP2 protein level remains unchanged in all groups. Normalization of dyslipidemia and IR by chia reduces plasma fatty acids (FAs) availability, suggesting that a different milieu prevents the robust translocation of FAT/CD36. This could reduce the influx of FAs, decreasing the elevated M-CPT1 activity and lipid storage and improving glucose oxidation in cardiac muscles of SRD-fed rats.

Abstract
Obesity as part of metabolic syndrome is a major lifestyle disorder throughout the world. Current drug treatments for obesity produce small and usually unsustainable decreases in body weight with the risk of major adverse effects. Surgery has been the only treatment producing successful long-term weight loss. As a different but complementary approach, lifestyle modification including the use of functional foods could produce a reliable decrease in obesity with decreased comorbidities. Functional foods may include fruits such as berries, vegetables, fibre-enriched grains and beverages such as tea and coffee. Although health improvements continue to be reported for these functional foods in rodent studies, further evidence showing the translation of these results into humans is required. Thus, the concept that these fruits and vegetables will act as functional foods in humans to reduce obesity and thereby improve health remains intuitive and possible rather than proven.

Abstract
n-3 Long-chain PUFA up-regulate intestinal lipid metabolism. However, whether these metabolic effects of PUFA on intestine are mediated by AMP-activated protein kinase (AMPK) remains to be elucidated. To determine the effects of α-linolenic acid (ALA) on intestinal fatty acid (FA) metabolism and whether these effects were affected by AMPK deletion, mice deficient in the catalytic subunit of AMPKα1 or AMPKα2 and wild-type (WT) mice were fed either a high-fat diet (HF) or HF supplemented with ALA (HF-A). The results showed that ALA supplementation decreased serum TAG content in WT mice. ALA also increased mRNA expression of genes (carnitine palmitoyltransferase 1a, acyl-CoA oxidase 1, medium-chain acyl-CoA dehydrogenase, cytochrome P450 4A10 and pyruvate dehydrogenase kinase isoenzyme 4a) involved in intestinal lipid oxidation and mRNA expression of TAG synthesis-related genes (monoacylglycerol O-acyltransferase 2, diacylglycerol O-acyltransferases 1 and 2) in WT mice. Consistent with these, expression levels of phosphorylated AMPKα1 and AMPKα2 were also increased in WT mice after ALA addition. However, in the absence of either AMPKα1 or AMPKα2, ALA supplementation failed to increase intestinal lipid oxidation. In addition, no significant effects of either diet (HF and HF-A) or genotype (WT, AMPKα1(-/-) and AMPKα2(-/-)) on FA uptake in the intestine and faecal TAG output were observed. Our results suggest that AMPK is indispensable for the effects of ALA on intestinal lipid oxidation.

Abstract
Salvia officinalis is used as a dietary supplement with diverse medicinal activity (e.g. antidiabetic and antiatherosclerotic effects). The plant also exerts profound cytotoxicity toward cancer cells. Here, we investigated possible modes of action to explain its activity toward drug-resistant tumor cells. Log10IC50 values of two constituents of S. officinalis (ursolic acid, pomolic acid) were correlated to the expression of ATP-binding cassette (ABC) transporters (P-glycoprotein/ABCB1/MDR1, MRP1/ABCC1, BCRP/ABCG2) and epidermal growth factor receptor (EGFR) or mutations in RAS oncogenes and the tumor suppressor gene TP53 of the NCI panel of cell lines. Gene expression profiles predicting sensitivity and resistance of tumor cells to these compounds were determined by microarray-based mRNA expressions, COMPARE, and hierarchical cluster analyses. Furthermore, the binding of both plant acids to key molecules of the NF-κB pathway (NF-κB, I-κB, NEMO) was analyzed by molecular docking. Neither expression nor mutation of ABC transporters, oncogenes, or tumor suppressor genes correlated with log10IC50 values for ursolic acid or pomolic acid. In microarray analyses, many genes involved in signal transduction processes correlated with cellular responsiveness to these compounds. Molecular docking indicated that the two plant acids strongly bound to target proteins of the NF-κB pathway with even lower free binding energies than the known NF-κB inhibitor MG-132. They interacted more strongly with DNA-bound NF-κB than free NF-κB, pointing to inhibition of DNA binding by these compounds. In conclusion, the lack of cross-resistance to classical drug resistance mechanisms (ABC-transporters, oncogenes, tumor suppressors) may indicate a promising role of the both plant acids for cancer chemotherapy. Genes involved in signal transduction may contribute to the sensitivity or resistance of tumor cells to ursolic and pomolic acids. Ursolic and pomolic acid may target different steps of the NF-κB pathway to inhibit NF-κB-mediated functions.

Abstract
Background n-3 long chain polyunsaturated fatty acid (n-3 LC PUFA) increases β-oxidation and limits lipid accumulation in adipocytes. The current study was conducted to determine whether their precursor alpha-linolenic acid (ALA) could also exert the above effects and how AMP-activated protein kinase (AMPK) was involved. Methods AMPKα1−/−, AMPKα2−/− mice and wild-type (WT) mice were fed a high-fat diet (HFD) or HFD with ALA. Body weight was recorded weekly and serum was collected. Adipocytes size and expression of key players involved in mitochondrial biogenesis and lipid oxidation were also measured. Results Our results showed an elevated serum adiponectin level and a decreased leptin and insulin level in WT mice fed HFD with ALA when compared with WT mice fed HFD. In addition, dietary ALA decreased epididymal adiposity and adipocytes size in WT mice. At protein level, mitochondrial genes (peroxisome proliferator-activated receptor gamma coactivator 1 alpha [PGC1α] and nuclear respiratory factor-1 [nrf1]) and β-oxidation related genes (carnitine palmitoyltransferase 1A [CPT1a] and peroxisome proliferator-activated receptor alpha [PPARα]) were upregulated by dietary ALA in epididymal fat of WT mice. Consistently, dietary ALA also increased mitochondrial genomic DNA copy numbers. Moreover, lipogenesis was repressed by dietary ALA, indicated by that expression of fatty acid synthase (FAS), acetyl CoA carboxylase (ACC) and stearoyl-CoA desaturase 1 (SCD1) were decreased. However, these aforementioned effects were abolished in the AMPKα1 and AMPKα2 knockout mice. Conclusions Our results suggest that ALA could improve adipose tissue function and its anti-adipogenic effects are dependent on AMPK.

Abstract
The widespread acceptance that increased dietary n-3 polyunsaturated fatty acids (PUFAs), especially α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), improve health is based on extensive studies in animals, isolated cells and humans. Visceral adiposity is part of the metabolic syndrome, together with insulin resistance, dyslipidemia, hypertension and inflammation. Alleviation of metabolic syndrome requires normalization of insulin release and responses. This review assesses our current knowledge of the mechanisms that allow n-3 PUFAs to improve insulin secretion and sensitivity. EPA has been more extensively studied than either ALA or DHA. The complex actions of EPA include increased G-protein-receptor-mediated release of glucagon-like peptide 1 (GLP-1) from enteroendocrine L-cells in the intestine, up-regulation of the apelin pathway and down-regulation of other control pathways to promote insulin secretion by the pancreatic β-cells, together with suppression of inflammatory responses to adipokines, inhibition of peroxisome proliferator-activated receptor α actions and prevention of decreased insulin-like growth factor-1 secretion to improve peripheral insulin responses. The receptors involved and the mechanisms of action probably differ for ALA and DHA, with antiobesity effects predominating for ALA and anti-inflammatory effects for DHA. Modifying both GLP-1 release and the actions of adipokines by n-3 PUFAs could lead to additive improvements in both insulin secretion and sensitivity.
