Abstract

BACKGROUND: The prevalence of obesity and related disorders such as metabolic syndrome and diabetes has vastly increased throughout the world. Recent insights have generated an entirely new perspective suggesting that our microbiota might be involved in the development of these disorders. This represents an area of scientific need, opportunity and challenge. The insights gleaned should help to address several pressing global health problems.CONTENT: Our bowels have two major roles: the digestion and absorption of nutrients and the maintenance of a barrier against the external environment. They fulfill these functions in the context of, and with the help from, tens of trillions of resident microbes, known as the gut microbiota. Studies have demonstrated that obesity and metabolic syndrome may be associated with profound microbiotal changes, and the induction of a metabolic syndrome phenotype through fecal transplants corroborates the important role of the microbiota in this disease. Dietary composition and caloric intake appear to swiftly regulate intestinal microbial composition and function.SUMMARY: The interaction of the intestinal microbial world with its host, and its mutual regulation, will become one of the important topics of biomedical research and will provide us with further insights at the interface of microbiota, metabolism, metabolic syndrome, and obesity. A better understanding of the interaction between certain diets and the human gut microbiome should help to develop new guidelines for feeding humans at various time points in their life, help to improve global human health, and establish ways to prevent or treat various food-related diseases.KEYWORDS: gut microbiota, obesity, metabolic syndrome, type 2 diabetes

Abstract

BACKGROUND: Low back pain (LBP) mostly caused by disc degeneration, reflects to a tremendous of health care system and economy. More knowledge about these underlying pathologies will improve the opportunities that may represent critical therapeutic targets.CONTENT: Basic research is advancing the understanding of the pathogenesis and management of LBP at the molecular and genetic levels. Cytokines such as matrix metalloproteinases, phospholipase A2, nitric oxide, and tumor necrosis factor-α are thought to contribute to the development of LBP. Mesenchymal stem cells (MSCs) transplant to cartilage-like cells and secrete extracellular matrix and encourage nucleus pulposus (NP) cell activity inhibiting NP cell apoptosis, together with some chemical mediators such as cytokines and growth factors become a safe and effective new strategy for intervertebral disc degeneration (IDD) treatment and regeneration.SUMMARY: IDD occurs where there is a loss of homeostatic balance with a predominantly catabolic metabolic profile. A basic understanding of the molecular changes occurring in the degenerating disc is important for practicing clinicians to help them to inform patients to alter lifestyle choices, identify beneficial or harmful supplements, or offer new biologic, genetic, or stem cell therapies.KEYWORDS: low back pain, intervertebral disc, degeneration, nucleus pulposus, annulus fibrosus, extracellular matrix, genetic, stem cells

Abstract

BACKGROUND: Prostate cancer (PCa) was the second most common type of cancer and the fifth leading cause of cancer-related death in men. The great challenge for physicians is being able to accurately predict PCa prognosis and treatment response in order to reduce PCa-specific mortality while avoiding overtreatment by identifying of when to intervene, and in which patients.CONTENT: Currently, PCa prognosis and treatment decision of PCa involved digital rectal examination, Prostate-Speciic Antigens (PSA), and subsequent biopsies for histopathological staging, known as Gleason score. However, each procedure has its shortcomings. Efforts to find a better clinically meaningful and non-invasive biomarkers still developed involving proteins, circulating tumor cells, nucleic acids, and the ‘omics' approaches.SUMMARY: Biomarkers for PCa will most likely be an assay employing multiple biomarkers in combination using protein and gene microarrays, containing markers that are differentially expressed in PCa.KEYWORDS: prostate cancer, PSA, biomarkers, nomograms, miRNA, proteomic, genomic, metabolomic

Abstract

BACKGROUND: Many previous studies have reported that central obesity is related to inflammation and endothelial dysfunction. It has also been reported that resistin can induce proinflammatory cytokines TNF-α and IL-6, which can result in endothelial dysfunction, although the role of resistin in human remains unclear. The aim of this study was to assess the role of resistin in influencing the proinflammatory cytokines TNF-α, IL-6, and chemokin MCP-1 in nondiabetic, central obese individuals. Results of this study are hoped to be useful to make a strategy for early prevention of endothelial dysfunction especially in obese individuals.METHOD: This was a cross-sectional study on 73 non diabetic obese male subjects (waist circumferences >90 cm). Resistin, hs-TNF-α, IL-6, MCP-1, VCAM-1 were assessed by ELISA. Statistical analysis was performed using SPSS for Windows v.11.5 with significance p<0.05. The correlations among biomarkers were assessed using Spearman’s Rho test.RESULTS: The study results showed a significant correlation between resistin and TNF-α (r=0.274, p<0.005), and a significant correlation between TNF-α and IL-6 (r=0.430, p<0.001). It was found that high concentration of resistin caused the concentration of TNF-α , IL-6 and MCP-1 to increase, and affected the increase of VCAM-1 (p=0.0030), A significant correlation between waist circumference and inflammation (hsCRP, r=0.296, p<0.005; IL-6, r=0.374, p<0.001 and HOMA IR, r=0.331, p<0.001) was also found.CONCLUSION: This study showed that the role of resistin in endothelial dysfunction occurred at a high concentration of resistin through induction of proinflammatory cytokines TNF-α, IL-6, and chemokin MCP-1. We suggest that inflammation in obesity starts with a positive feedback loop mechanism between resistin and TNF-α.KEYWORDS: obesity, inflammation, adipocytokines, resistin, tumor necrosis factor-α, interleukin-6, monocyte chemotactic protein-1, vascular cell adhesion molecule–1

Abstract

BACKGROUND: Obesity is a growing threat to global health by virtue of its association with insulin resistance, inflammation, hypertension, and dyslipidemia, collectively known as the metabolic syndrome (MetS). The nuclear receptors PPARα and PPARγ are therapeutic targets for hypertriglyceridemia and insulin resistance, respectively, and drugs that modulate these receptors are currently in clinical use. More recent work on the PPARδ has uncovered a dual benefit for both hypertriglyceridemia and insulin resistance, highlighting the broad potential of PPARs in the treatment of metabolic disease.CONTENT: We have learned much about PPARs, the metabolic fat sensors, and the molecular pathways they regulate. Through their distinct tissue distribution and specific target gene activation, the three PPARs together control diverse aspects of fatty acid metabolism, energy balance, insulin sensitivity glucose homeostasis, inflammation, hypertension and atherosclerosis. These studies have advanced our understanding of the etiology for the MetS. Mechanisms revealed by these studies highlight the importance of emerging concepts, such as the endocrine function of adipose tissue, tissue-tissue cross-talk and lipotoxicity, in the pathogenesis of type 2 diabetes mellitus and CVD.SUMMARY: The elucidation of key regulators of energy balance and insulin signaling have revolutionized our understanding of fat and sugar metabolism and their intimate link. The three ‘lipidsensing’ (PPARα, PPARγ and PPARδ) exemplify this connection, regulating diverse aspects of lipid and glucose homeostasis, and serving as bonafide therapeutic targets.KEYWORDS: Peroxisome Proliferator, Activated Receptor, Metabolic Syndrome

Abstract

BACKGROUND: Epidemiological data reveal parallel trends of decreasing sleep duration and increases in metabolic disorders such as obesity, diabetes and hypertension. There is growing evidence that these trends are mechanistically related.CONTENT: The circadian system orchestrates the temporal organization of many aspects of physiology, including metabolism, in synchrony with the 24 hours rotation of the Earth. The circadian system is a complex feedback network that involves interactions between the central nervous system and peripheral tissues. Circadian regulation is intimately linked to metabolic homeostasis and that dysregulation of circadian rhythms can contribute to disease. Conversely, metabolic signals also feed back into the circadian system, modulating circadian gene expression and behavior.SUMMARY: Both inter- and intraorgan desynchrony may be involved in the pathogenesis of cardiometabolic disease attributable to effects in brain and multiple metabolic tissues including heart, liver, fat, muscle, pancreas and gut. Efforts to dissect the molecular mediators that coordinate circadian, metabolic, and cardiovascular systems may ultimately lead to both improved therapeutics and preventive interventions.KEYWORDS: circadian rhythms, clock genes, nuclear receptor, sleep, obesity, cardiometabolic risk

Abstract

BACKGROUND: Giant transformations are going on currently in health care, and the greatest force behind this phenomenon is data.CONTENT: Big data has arrived into medicine field, lead to potential enhancement in accountability, quality, efficiency, and innovation. Most updated, artificial intelligence (AI) and machine-learning (ML) techniques rapidly developed, bring forth the big data analysis into more useful applications, from resource allocation to complex disease diagnosis. To realize this, a very large set of health-care data is needed for algorithms training and evaluation, including patients’ treatment data, patients respond to treatment, and personal patient information, such as genetic data, family history, health behavior, and vital signs.SUMMARY: Precision Health involving preventive, predictive, personalized and precise. The arrival of AI and ML will enhance and facilitates the improvement of this relationship through better accuracy, productivity, and workflow, thus develop a health system that will go beyond just curing disease, but further into wellness that preventing disease before it strikes, thus the patient–doctor bond is expected to be reformed and not be eroded.KEYWORDS: artificial intelligence, machine learning, deep learning, electronic health records, big data

Abstract

BACKGROUND: Atherosclerosis is a leading cause of vascular disease worldwide. During the past several decades, landmark discoveries in the field of vascular biology have evolved our understanding of the biology of blood vessels and the pathobiology of local and systemic vascular disease states and have led to novel disease-modifying therapies for patients. This review is made to understand the molecular mechanism of atherosclerosis for these future therapies.CONTENT: Advances in molecular biology and -omics technologies have facilitated in vitro and in vivo studies which revealed that blood vessels regulate their own redox milieu, metabolism, mechanical environment, and phenotype, in part, through complex interactions between cellular components of the blood vessel wall and circulating factors. Dysregulation of these carefully orchestrated homeostatic interactions has also been implicated as the mechanism by which risk factors for cardiopulmonary vascular disease lead to vascular dysfunction, structural remodeling and, ultimately, adverse clinical events.SUMMARY: Atherosclerosis is a heterogeneous disease, despite a common initiating event of apoB-lipoproteins. Despite of acute thrombotic complications, an adequate resolution response is mounted, where efferocytosis prevents plaque necrosis and a reparative scarring response (the fibrous cap) prevents plaque disruption. However, a small percentage of developing atherosclerotic lesions cannot maintain an adequate resolution response, which leading to the formation of clinically dangerous plaques that can trigger acute lumenal thrombosis and tissue ischemia and infarction.KEYWORDS: atherosclerosis, oxidative stress, inflammation, efferocytosis, foam cells, thrombosis

Abstract

BACKGROUND: The epidemic of obesity and type 2 diabetes presents a serious challenge to scientific and biomedical communities worldwide. There has been an upsurge of interest in the adipocyte coincident with the onset of the obesity epidemic and the realization that adipose tissue plays a major role in the regulation of metabolic function.CONTENT: Adipose tissue, best known for its role in fat storage, can also suppress weight gain and metabolic disease through the action of specialized, heat-producing adipocytes. Brown adipocytes are located in dedicated depots and express constitutively high levels of thermogenic genes, whereas inducible ‘brown-like’ adipocytes, also known as beige cells, develop in white fat in response to various activators. The activities of brown and beige fat cells reduce metabolic disease, including obesity, in mice and correlate with leanness in humans. Many genes and pathways that regulate brown and beige adipocyte biology have now been identified, providing a variety of promising therapeutic targets for metabolic disease.SUMMARY: The complexity of adipose tissue presents numerous challenges but also several opportunities for therapeutic intervention. There is persuasive evidence from animal models that enhancement of the function of brown adipocytes, beige adipocytes or both in humans could be very effective for treating type 2 diabetes and obesity. Moreover, there are now an extensive variety of factors and pathways that could potentially be targeted for therapeutic effects. In particular, the discoveries of circulating factors, such as irisin, fibroblast growth factor (FGF)21 and natriuretic peptides, that enhance brown and beige fat function in mice have garnered tremendous interest. Certainly, the next decade will see massive efforts to use beige and brown fat to ameliorate human metabolic disease.KEYWORDS: obesity, white adipose tissue, brown adipose tissue, beige adipose tissue, adipose organ, thermogenesis, energy expenditure

Abstract

BACKGROUND: Since our conception to death, we were permanently exposed to nutrition. Indeed, food intake is the key of the environmental factor that modulates our gene. Nutrigenomics focus on how common dietary chemicals altering an individual’s genetic makeup including genome, proteome, and metabolome. While nutrigenetics refer to how the genetic variation gives different responses to nutrients.CONTENT: Nutrigenomics applied the high-throughput genomic-related tools to find out the influence of nutrients on the genes’ expression. While nutrigenetics (nutritional genetics) focus on the heterogenous response of gene variants to nutrients and dietary factors. Application nutrigenomics and nutrigenetics, integrated with system biology result in a precision nutrition as a relevant precise personal dietary change recommendation, thus will increase the motivation and sustain to whom the intervention is being delivered.SUMMARY: Individual diet recommendation is not simple. Many factors and tools should be involved adequately. The application of integrated -omics approaches, together with nutrigenomic and nutrigenetics for novel biomarker discovering and precision nutrition tailoring were expected to develop a healthier lifestyle and behavior.KEYWORDS: nutrigenetics, nutrigenomics, precision nutrition, metabolomics, system biology
