Bioactive compounds of peanut skin in prevention and adjunctive treatment of chronic non-communicable diseases.

The global prevalence of cancer continues to increase, so does its mortality. Strategies that can prevent/treat this condition are therefore required, especially low-cost and low-toxicity strategies. Bioactive compounds of plant origin have been presented as a good alternative. In this scenario, due to its abundant polyphenolic content (around 60 to 120 times greater than that of the grain), peanut skin by-products stand out as a sustainable source of food bioactives beneficial to human health. Investigated studies highlighted the importance of peanut skin for human health, its phytochemical composition, bioactivity and the potential for prevention and/or adjuvant therapy in cancer, through the advanced search for articles in the Virtual Health Library (VHL), Science direct and the Mourisco platform of the FioCruz Institute, from 2012 to 2022. Using the keywords, "peanut skin" AND "cancer" AND NOT "allergy", the words "peanut testa" and "peanut peel" were included replacing "peanut skin". 18 articles were selected from Plataforma Mourisco, 26 from Science Direct and 26 from VHL. Of these, 7 articles evaluated aspects of cancer prevention and/or treatment. Promising benefits were found in the prevention/treatment of chronic non-communicable diseases in the use of peanut and peanut skin extracts, such as cholesterolemia and glucose control, attenuation of oxidative stress and suppressive action on the proliferation and metabolism of cancer cells.

Orthotopic Model of Hepatocellular Carcinoma in Mice.

Orthotopic models of hepatocellular carcinoma (HCC) consist in the implantation of tumor cells into the liver by direct intrahepatic injection. In this model, tumorigenesis is triggered within the hepatic microenvironment, thus mimicking the metastatic behavior of HCC. Herein, we detail a surgically mediated methodology that allows the reproducible and effective induction of liver-sessile tumors in mice. We enumerate the steps to be followed before and after the surgical procedure, including HCC cell preparation, the quantity of cancer cells to be injected, presurgical preparation of the mice, and finally, postoperative care. The surgical procedure involves laparotomy to expose the liver, injection of cells into the left-lateral hepatic lobe, and closure of the incision with sutures followed by wound clips. We also provide information concerning the subsequent tumor growth follow-up, as well as the application of bioluminescence imaging to monitor tumor development.

A Mouse Model of Non-Alcoholic Steatohepatitis and Hepatocellular Carcinoma Induced by Western Diet and Carbon Tetrachloride.

Non-alcoholic steatohepatitis (NASH) is a severe form of non-alcoholic fatty liver disease (NAFLD). Obesity is a known risk factor of NASH, which, in turn, increases the risk of developing cirrhosis (liver scarring) and hepatocellular carcinoma (HCC). In addition to being a potentially life-threatening condition, public health concerns surrounding NASH are amplified by the lack of FDA-approved treatments. Although various preclinical models reflecting both the histopathology and the pathophysiological progression of human NASH exist, most of these models are diet-based and require 6-13 months for NASH symptom manifestation. Here, we describe a simple and rapid-progression model of NASH and NASH-driven HCC in mice. Mice received a western diet equivalent (WD; i.e., a high-fat, high-fructose, and high-cholesterol diet), high-sugar water (23.1 g/L fructose and 18.9 g/L glucose), and weekly intraperitoneal injections of carbon tetrachloride (CCl4) at a dose of 0.2 µL/g of body weight. The resulting phenotype, consisting in liver fibrosis and HCC, appeared within 24 weeks of diet/treatment initiation and presented similar histological and transcriptomic features as human NASH and NASH-driven HCC, thereby supporting the adequacy of this preclinical model for the development and evaluation of drugs that can prevent or reverse these diseases.

A Mouse Model of Hepatocellular Carcinoma Induced by Streptozotocin and High-Fat Diet.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and the second most common cause of cancer-related death. HCC is associated to chronic diseases such as viral hepatitis, alcoholic, and non-alcoholic fatty liver disease (NAFLD), diabetes mellitus, and obesity, among others. Although pre-clinical models have been investigated to mimic the transition from NAFLD to HCC, they do not accurately reproduce the phenotypic evolution from simple steatosis to steatohepatitis, fibrosis/cirrhosis, and HCC. Hence, these models have failed to demonstrate the influence of diabetes on hepatic carcinogenesis. Here, we report a novel mouse model of HCC triggered by fast-developing diabetes and NAFLD. The first step consists in a single intraperitoneal injection of a low dose of streptozotocin into neonatal C57BL/6J mice to induce type 2 diabetes. In a second step, mice are fed with high-fat diet to accelerate the development of simple steatosis. Continuous high-fat diet exacerbates hepatic fat deposition with increased lobular inflammation (by activation of foam cell-like macrophages) and fibrosis (by activating hepatic stellate cells), two representative pathological traits of steatohepatitis/fibrosis. After 20 weeks, all mice developed multiple HCCs. This model of hepatic carcinogenesis triggered by diabetes mellitus and NAFLD offers the advantage of being rapid and accurately recapitulates the pathogenesis of human HCC without the need of administering hepatic carcinogens.

Isolation of Primary Mouse Hepatocytes and Non-Parenchymal Cells from a Liver with Precancerous Lesions.

In the early stages of liver carcinogenesis, rare hepatocytes and cholangiocytes are transformed into preneoplastic cells, which can progressively acquire a neoplastic phenotype, favored by the failure of natural antitumor immunosurveillance. The detailed study of both hepatic parenchymal (e.g., hepatocytes) and non-parenchymal cells (NPCs), such as immune cells, could help understand the cellular microenvironment surrounding these pre-cancerous and neoplastic lesions.Cultures of primary hepatocytes are of interest in various biomedical research disciplines, serving as an ex vivo model for liver physiology. Obtaining high viability and yield of primary mouse hepatocytes and other liver cell populations is technically challenging, thus limiting their use. In the first section of the current chapter, we introduce a protocol based on the two-step collagenase perfusion technique (by inferior vena cava) to isolate hepatocytes and, to a lower extent, NPCs and detailed the different considerations to take into account for a successful perfusion. The liver is washed by perfusion, hepatocytes are dissociated with collagenase, and different cell populations are separated by centrifugation. Various techniques have been described for the isolation of healthy and malignant hepatocytes; however, the viability and purity of the isolated cells is frequently not satisfactory. Here, we significantly optimized this protocol to reach improved yield and viability of the hepatocytes and concomitantly obtain preserved NPC populations of the liver.Within NPCs, tissue-resident or recruited immune cells are essential actors regulating hepatocarcinogenesis. However, simultaneous isolation of hepatic leukocytes together with other cell types generally yields low immune cell numbers hindering downstream application with these cells. In the second section of this chapter, as opposed to the first section primarily aiming to isolate hepatocytes, we present a tissue dissociation protocol adapted to efficiently recover leukocytes from non-perfused bulk (pre-)cancerous livers. This protocol has been optimized to be operator-friendly and fast compared to other liver processing methods, allowing easy simultaneous sample processing to retrieve hepatic (tumor-infiltrating) immune cells.

Targeted Analysis of Glycerophospholipids and Mono-, Di-, or Tri-Acylglycerides in Liver Cancer.

The metabolic rearrangements of hepatic metabolism associated with liver cancer are still incompletely understood. There is an ongoing need to identify novel and more efficient diagnostic biomarkers and therapeutic targets based on the metabolic mechanisms of these diseases. In comparison to traditional diagnostic biomarkers, metabolomics is a comprehensive technique for discovering chemical signatures for liver cancer screening, prediction, and earlier diagnosis. Lipids are a large and diverse group of complex biomolecules that are at the heart of liver physiology and play an important role in the development and progression of cancer. In this chapter, we described two detailed protocols for targeted lipids analysis: glycerophospholipids and mono, di, tri-acylglycerides, both by Flow Injection Analysis (FIA) HPLC coupled to a SelexIon/QTRAP 6500+ system. These approaches provide a targeted lipidomic metabolomic signature of dissimilar metabolic disorders affecting liver cancers.

Biomarker Identification in Liver Cancers Using Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) Imaging: An Approach for Spatially Resolved Metabolomics.

Liver cancers are characterized by interindividual and intratumoral heterogeneity, which makes early diagnosis and the development of therapies challenging. Desorption electrospray ionization mass spectrometry (DESI-MS) imaging is a potent and sensitive MS ionization technique for direct, unaltered 2D and 3D imaging of metabolites in complex biological samples. Indeed, DESI gently desorbs and ionizes analyte molecules from the sample surface using an electrospray source of highly charged aqueous spray droplets in ambient conditions. DESI-MS imaging of biological samples allows untargeted analysis and characterization of metabolites in liver cancers to identify new biomarkers of malignancy. In this chapter, we described a detailed protocol using liver cancer samples collected and stored for histopathology examination, either as frozen or as formalin-fixed, paraffin-embedded specimens. Such hepatocellular carcinoma samples can be subjected to DESI-MS analyses, illustrating the capacity of spatially resolved metabolomics to distinguish malignant lesions from adjacent normal liver tissue.

Inhibition of acyl-CoA binding protein (ACBP) by means of a GABAARγ2-derived peptide.

Acyl-CoA binding protein (ACBP) encoded by diazepam binding inhibitor (DBI) is an extracellular inhibitor of autophagy acting on the gamma-aminobutyric acid A receptor (GABAAR) γ2 subunit (GABAARγ2). Here, we show that lipoanabolic diets cause an upregulation of GABAARγ2 protein in liver hepatocytes but not in other major organs. ACBP/DBI inhibition by systemically injected antibodies has been demonstrated to mediate anorexigenic and organ-protective, autophagy-dependent effects. Here, we set out to develop a new strategy for developing ACBP/DBI antagonists. For this, we built a molecular model of the interaction of ACBP/DBI with peptides derived from GABAARγ2. We then validated the interaction between recombinant and native ACBP/DBI protein and a GABAARγ2-derived eicosapeptide (but not its F77I mutant) by pull down experiments or surface plasmon resonance. The GABAARγ2-derived eicosapeptide inhibited the metabolic activation of hepatocytes by recombinant ACBP/DBI protein in vitro. Moreover, the GABAARγ2-derived eicosapeptide (but not its F77I-mutated control) blocked appetite stimulation by recombinant ACBP/DBI in vivo, induced autophagy in the liver, and protected mice against the hepatotoxin concanavalin A. We conclude that peptidomimetics disrupting the interaction between ACBP/DBI and GABAARγ2 might be used as ACBP/DBI antagonists. This strategy might lead to the future development of clinically relevant small molecules of the ACBP/DBI system.

Acyl-CoA binding protein for the experimental treatment of anorexia.

Extracellular acyl-coenzyme A binding protein [ACBP encoded by diazepam binding inhibitor (DBI)] is a phylogenetically ancient appetite stimulator that is secreted in a nonconventional, autophagy-dependent fashion. Here, we show that low ACBP/DBI plasma concentrations are associated with poor prognosis in patients with anorexia nervosa, a frequent and often intractable eating disorder. In mice, anorexia induced by chronic restraint stress (CRS) is accompanied by a reduction in circulating ACBP/DBI concentrations. We engineered a chemical-genetic system for the secretion of ACBP/DBI through a biotin-activatable, autophagy-independent pathway. In transgenic mice expressing this system in hepatocytes, biotin-induced elevations in plasma ACBP/DBI concentrations prevented anorexia induced by CRS or chemotherapeutic agents including cisplatin, doxorubicin, and paclitaxel. ACBP/DBI reversed the CRS or cisplatin-induced increase in plasma lipocalin-2 concentrations and the hypothalamic activation of anorexigenic melanocortin 4 receptors, for which lipocalin-2 is an agonist. Daily intravenous injections of recombinant ACBP/DBI protein or subcutaneous implantation of osmotic pumps releasing recombinant ACBP/DBI mimicked the orexigenic effects of the chemical-genetic system. In conclusion, the supplementation of extracellular and peripheral ACBP/DBI might constitute a viable strategy for treating anorexia.

Identificação de risco cardiovascular pela razão triglicerídeo/HDL-colesterol em pacientes com doença renal crônica em hemodiálise / Identification of cardiovascular risk by triglyceride/HDL-cholesterol ratio in patients with chronic renal disease in hemodialysis

OBJETIVOS: Identificar o risco cardiovascular pela razão triglicerídeo/colesterol ligado à lipoproteína de alta densidade (TG/HDL-c) e verificar a sua associação com fatores sociodemográficos, parâmetros clínicos e índice de massa corporal em pacientes com doença renal crônica em hemodiálise. MÉTODOS: Estudo do tipo transversal, no qual foram avaliados pacientes com doença renal crônica em hemodiálise. A amostragem foi do tipo não probabilística de conveniência. A coleta de dados sociodemográficos foi realizada por meio de entrevista com questionário semiestruturado, e os dados clínicos e laboratoriais foram obtidos em consulta aos prontuários. Para identificação do risco cardiovascular, a razão TG/HDL-c foi calculada a partir dos valores plasmáticos de triglicerídeos (mg/dL) e colesterol ligado à lipoproteína de alta densidade (mg/dL). O ponto de corte para TG/HDL-c considerado como indicativo de risco cardiovascular foi de ≥3,8 mg/dL. Para análise estatística foi utilizado o teste qui-quadrado, e o nível de significância considerado foi de 5% (p<0,05). RESULTADOS: Foram avaliados 71 pacientes, cuja média de idade foi 49,9±13,2 anos, sendo 28 mulheres (50,1±13,2 anos) e 43 homens (49,7±13,2 anos). Entre os 71 pacientes, 31 (43,66%) apresentavam risco cardiovascular caracterizado pela relação TG/HDL-c ≥3,8 mg/dL. Em geral observou-se semelhança quanto ao perfil dos pacientes com e sem risco cardiovascular. Entretanto, nos pacientes que possuíam risco cardiovascular a maior proporção foi do sexo masculino (77,42%), enquanto nos que não possuíam esse risco, o sexo feminino foi mais frequente (52,50%). Esta variável apresentou diferença significativa entre os grupos com e sem risco cardiovascular (p=0,011). CONCLUSÕES: Nesta amostra de pacientes com doença renal crônica em hemodiálise, a razão TG/HDL-c identificou alto índice de risco cardiovascular, sendo que esse risco foi significativamente associado ao sexo masculino.

AIMS: To identify cardiovascular risk by triglyceride/high density lipoprotein cholesterol ratio (TG/HDL-c) and to verify its association with socio-demographic factors, clinical parameters and body mass index in patients with chronic renal disease on hemodialysis. METHODS: Cross-sectional study, in which patients with chronic kidney disease in hemodialysis were evaluated. A non-probability convenience sampling was used. Sociodemographic data were collected through a semi-structured questionnaire interview, and clinical and laboratory data were obtained from the medical records. For the identification of cardiovascular risk, the TG/HDL-c ratio was calculated from plasma triglycerides (mg/dL) and high density lipoprotein cholesterol (mg/dL). The cut-off point for TG/HDL-c considered to be indicative of cardiovascular risk was ≥3.8 mg/dL. For statistical analysis, the chi-square test was used, and the significance level was set at 5% (p <0.05). RESULTS: A total of 71 patients were evaluated, with a mean age of 49.9±13.2 years, being 28 women (50.1±13.2 years) and 43 men (49.7±13.2 years). Among the 71 patients, 31 (43.66%) had cardiovascular risk characterized by the TG/HDL-c ratio ≥3.8 mg/dL. In general, the profile of patients with and without cardiovascular risk was similar. However, in patients with cardiovascular risk there was a higher proportion of males (77.42%), while in those who did not have this risk, the female gender was morefrequent (52.50%). This variable showed a significant. difference between the groups with and without cardiovascular risk (p=0.011). CONCLUSIONS: In this sample of patients with chronic kidney disease on hemodialysis, the TG/HDL-c ratio identified a high cardiovascular risk index, which was significantly associated with males.

Ácidos graxos essenciais ômega-3 e ômega-6 no leite materno e sua associação com o desenvolvimento infantil: revisão de literatura / Omega-3, omega-6 essential fatty acids and its association with child development: a literature review

O objetivo deste trabalho foi estudar os benefícios que os ácidos graxos essenciais ômega-3 e ômega-6, presentes no leite materno, podem trazer para o desenvolvimento infantil. Trata-se de uma revisão sistemática nas bases de dados PUBMED e BIREME entre 2009 a 2013, utilizando os termos: "Ácidos Graxos Ômega-3", "Ácidos Graxos Ômega-6" e "breast feeding". Foram selecionados 29 artigos, onde apenas 8 permaneceram após leitura dos mesmos na integra, excluindo artigos de revisão, de nota técnica, sem associação entre mãe-filho, assuntos não relacionados com o desenvolvimento infantil e com metodologia baseada em entrevista ou aplicação de questionário. Os principais resultados encontrados pelos autores foram à ingestão destes ácidos durante a gestação como influência no desenvolvimento neurológico, visual e físico do lactente; a ocorrência de variações dos ácidos graxos essenciais, no leite humano, obtidos em diferentes idades gestacionais e estágios de lactação; a elevação nos níveis de ômega-3 e ômega-6, respectivamente, em crianças amamentadas exclusivamente e em crianças alimentadas com fórmulas suplementadas. A associação da ingesta adequada dos ácidos graxos essenciais, ômega-3 e 6, durante os períodos de gestação e lactação com o desenvolvimento infantil a longo prazo foi observada na maioria dos estudos.(AU)

This work aims to study the benefits that omega-3 and omega-6 essential fatty acids, present in breast milk, can bring to a child's development. This is a systematic review that national and international publications were assess in PUBMED and BIREME data from 2009 to 2013 using the terms: "Fatty Acids Omega3", "Fatty Acids Omega-6" and "breast feeding". A total of 29 articles were selected, where only 8 remained the after been read in full, excluding review articles, technical notes, the ones with no association between parent­child, with issues not related to child development and the ones based on an interview or a questionnaire methodology. The main results found by the authors were the intake of these acids during pregnancy as an influence on neurological, visual and physical development of infants; variations occurrence of essential fatty acids in human milk obtained at different gestational ages and stages of lactation, the increased levels of omega-3 and omega-6, respectively, in infants exclusively breastfed and formula-fed. The association of adequate intake of essential fatty acids omega-3 and 6 during the periods of pregnancy and lactation with the child long-term development was observed in most studies.(AU)
