Abstract
Breast cancer cells MCF-7 and MDA-MB-231 were treated with Tamoxifen (5 μM) or Paclitaxel (1 μM) or with a combination of the two drugs. Herein, we have employed gas chromatography coupled with mass spectroscopy to identify metabolic changes occurring as response to different drug treatments. We report the identification of sixty-one metabolites and overall the two studied cell lines showed a distinct metabolomic profile from each other. Further data analysis indicates that a total of 30 metabolites were significantly differentially abundant in MCF-7 drug-treated cells, most of the metabolic changes occurred when cells were treated with either Tamoxifen (15) or Paclitaxel (25). On the other side, a total of 31 metabolites were significantly differentially abundant in MDA-MB-31 cells with drug treatment. Similarly, to MCF-7 most of the metabolic changes occurred when cells were treated with either Tamoxifen (19) or Paclitaxel (20). In conclusion, this report demonstrates that Tamoxifen and/or Paclitaxel treatment have a pronounced effect on the main metabolic pathways in both breast cancer (BC) cell lines (MCF-7 and MDA-MB231), which could be used as a foundation for future investigations to understand the possible effect of these drugs on different metabolic pathways. SIGNIFICANCE: Metabolic profiling of cancer cells is a promising tool in tumor diagnosis, biomarker discovery and drug treatment protocols, since cancer cells exhibit altered metabolism when compared to normal cells. Although numerous studies have reported the use of various OMICs applications to investigate breast cancer cells, very few of these have performed thorough screening of metabolites in such cells. Our investigation highlights the first study to characterize MCF7 and MDA-MB-231 cancer cells treated with Tamoxifen and/or Paclitaxel and to identify the affected metabolic pathways. Such findings might play an important role in revealing the molecular bases of the underlying mechanism of action of these two frontline anti-breast cancer drugs.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE: GeGen Decoction, a well-known Chinese herbal formula, is widely used in China and other Asian countries to treat gynecological diseases, including primary dysmenorrhea. Pharmacological studies have confirmed that GeGen Decoction is able to inhibit spasmodic contractions of the uterus in vivo and in vitro.
AIM OF THE STUDY: The objective of this study is to examine the efficacy and safety of GeGen Decoction on primary dysmenorrheic patients.
METHODS: This was a randomized, double-blinded, placebo-controlled trial. GeGen Decoction or placebo was administered a week before the expected start of each cycle for three consecutive menstrual periods. Between-group differences in pain intensity were detected by visual analogue scale (VAS). In addition, serum levels of arginine vasopressin (AVP) and estrogen (E) were examined by enzyme-linked immunosorbent assay. Metabolomic analysis was further used to evaluate the influence of GeGen Decoction on the metabolomics of primary dysmenorrheic patients.
RESULTS: A total of 71 primary dysmenorrheic women were recruited and 30 participants met the criteria were randomized into GeGen Decoction or placebo group. After three consecutive menstrual cycles' treatment, the VAS score of the GeGen Decoction group was significantly lower than that of the placebo group. Both serum levels of AVP and E decreased after GeGen Decoction administration, while the placebo seemed to have little effect on either of the index. Moreover, after GeGen Decoction treatment, seven important metabolites were identified by metabolomic analysis compared to the placebo group. No abnormalities in blood biochemical and routine physical examination pre and post GeGen Decoction intervention were observed.
CONCLUSIONS: GeGen Decoction can remarkably relieve the severity of menstrual pain without obvious adverse effects. Its therapeutic effect on primary dysmenorrhea might be related to the regulation of pituitary hypothalamic ovarian hormones, and interfering with the metabolic change.

Abstract
INTRODUCTION: Prion disease is a form of neurodegenerative disease caused by the misfolding and aggregation of cellular prion protein (PrPC). The neurotoxicity of the misfolded form of prion protein, PrPSc still remains understudied. Here we try to investigate this issue using a metabolomics approach.
OBJECTIVES: The intention was to identify and quantify the small-in-size and water-soluble metabolites extracted from mice brains infected with the Rocky Mountain Laboratory isolate of mouse-adapted scrapie prions (RML) and track changes in these metabolites during disease evolution.
METHODS: A total of 73 mice were inoculated with RML prions or normal brain homogenate control; brains were harvested at 30, 60, 90, 120 and 150 days post-inoculation (dpi). We devised a high-efficiency metabolite extraction method and used nuclear magnetic resonance spectroscopy to identify and quantify 50 metabolites in the brain extracts. Data were analyzed using multivariate approach.
RESULTS: Brain metabolome profiles of RML infected animals displayed continuous changes throughout the course of disease. Among the analyzed metabolites, the most noteworthy changes included increases in myo-inositol and glutamine as well as decreases in 4-aminobutyrate, acetate, aspartate and taurine.
CONCLUSION: We report a novel metabolite extraction method for lipid-rich tissue. As all the major metabolites are identifiable and quantifiable by magnetic resonance spectroscopy, this study suggests that tracking of neurochemical profiles could be effective in monitoring the progression of neurodegenerative diseases and useful for assessing the efficacy of candidate therapeutics.

Abstract
Hürthle cell carcinoma (HCC) is a recurrent subtype of non-medullary thyroid cancer. HCC is characterized by profound whole-chromosome instability (w-CIN), resulting in a near-homozygous genome (NHG), a phenomenon recently attributed to reactive oxygen species (ROS) generated during mitosis by malfunctioning mitochondria. We studied shared metabolic traits during standard and glucose-depleted cell culture in thyroid cancer cell lines (TCCLs), with or without a NHG, using quantitative analysis of extra and intracellular metabolites and ROS production following inhibition of complex III with antimycin A. We found that the XTC.UC1 and FTC-236 cell lines (both NHG) are functionally impaired in complex I and produce significantly more superoxide radicals than SW579 and BHP 2-7 (non-NHG) after challenge with antimycin A. FTC-236 showed the lowest levels of glutathione and SOD2. XTC.UC1 and FTC-236 both exhibited reduced glycolytic activity and utilization of alternative sources to meet energy demands. Both cell lines also shared low levels of α-ketoglutarate and high levels of creatine, phosphocreatine, uridine diphosphate-N-acetylglucosamine, pyruvate and acetylcarnitine. Furthermore, the metabolism of XTC.UC1 was skewed towards the de novo synthesis of aspartate, an effect that persisted even in glucose-free media, pointing to reductive carboxylation. Our data suggests that metabolic reprogramming and a subtle balance between ROS generation and scavenging/conversion of intermediates may be involved in ROS-induced w-CIN in HCC and possibly also in rare cases of follicular thyroid cancer showing a NHG.

Abstract
The zoonotic bacterium Leptospira interrogans is the aetiological agent of leptospirosis, a re-emerging infectious disease that is a growing public health concern. Most human cases of leptospirosis result from environmental infection. Biofilm formation and its contribution to the persistence of virulent leptospires in the environment or in the host have scarcely been addressed. Here, we examined spatial and time-domain changes in biofilm production by L. interrogans. Our observations showed that biofilm formation in L. interrogans is a highly dynamic process and leads to a polarized architecture. We notably found that the biofilm matrix is composed of extracellular DNA, which enhances the biofilm's cohesiveness. By studying L. interrogans mutants with defective diguanylate cyclase and phosphodiesterase genes, we show that biofilm production is regulated by intracellular levels of bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP) and underpins the bacterium's ability to withstand a wide variety of simulated environmental stresses. Our present results show how the c-di-GMP pathway regulates biofilm formation by L. interrogans, provide insights into the environmental persistence of L. interrogans and, more generally, highlight leptospirosis as an environment-borne threat to human health.

Abstract
BACKGROUND: Fatty acids have been implicated in early life immune development. Food allergy provides a clear phenotype of early allergic disease. Fish oil and vitamin D have immune-modulating properties. We aimed to identify the metabolomic profile of (i) infant food allergy and (ii) factors linked to food allergy in past studies such as fish oil supplementation and serum 25OHD3 levels in early life.
METHODS: NMR was used to quantify 73 metabolites in plasma of 1 year old infants from the Barwon Infant Study (n=485). Logistic regression models were used to examine associations between infant metabolome and food allergy in infants. Linear regression models were used to describe associations between maternal fish oil supplementation and 25OHD3 levels with infant metabolites.
RESULTS: A higher linoleic acid: total fatty acid (FA) ratio and phenylalanine level were associated with higher odds of food allergy. Antenatal fish oil supplementation was positively associated with docosahexaenoic acid (DHA) and omega-3 related metabolite levels. Postnatal 25OHD3 levels at 1 year of age were positively associated with several FA measures and creatinine and inversely with the saturated FA: total FA ratio. Only the postnatal 25OHD3 patterns persisted after adjustment for multiple comparisons.
CONCLUSIONS: Infants with food allergy had altered fatty acid profiles at one year. Fish oil supplementation in pregnancy was associated with higher DHA and omega-3 related metabolites at 1 year of age. Associations were modest and the most robustly altered metabolomic profiles were with postnatal 25OHD3 levels.

Abstract
Metabolomics involvement in the study of foods is steadily growing. Such a rise is a consequence of the increasing demand in the food sector to address challenges regarding the issues of food safety, quality, and authenticity in a more comprehensive way. Virgin olive oil (VOO) is a key product of the Mediterranean diet, with a globalized consumer interest as it may be associated with various nutritional and health benefits. Despite the strict legislation to protect this high added-value agricultural commodity and offer guarantees to consumers and honest producers, there are still analytical issues needing to be further addressed. Thus, this review aims to present the efforts made using targeted and untargeted metabolomics approaches, namely nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry-based techniques (mainly LC/GC-MS) combined with multivariate statistical analysis. Case-studies focusing on geographical/varietal classification and detection of adulteration are discussed with regards to the identification of possible markers. The advantages and limitations of each of the aforementioned techniques applied to VOO analysis are also highlighted.

Abstract
Systems vaccinology leverages high-throughput 'omics' technologies, such as transcriptomics, metabolomics, and mass cytometry, coupled with computational approaches to construct a global map of the complex processes that occur during an immune response to vaccination. Its goal is to define the mechanisms of protective immunity and to identify cellular and molecular correlates of vaccine efficacy. Emerging technological advances including integration of multi-omics datasets, and single-cell genomic and epigenomic profiling of immune responses, have invigorated systems vaccinology, and provide new insights into the mechanisms by which the cellular and molecular information underlying immune memory is stored in the innate and adaptive immune systems. Here, we will review these emerging directions in systems vaccinology, with a particular focus on the epigenome, and its impact on modulating vaccination induced memory in the innate and adaptive immune systems.

Abstract
The relationship between gut microbiota and type 2 diabetes mellitus (T2DM) has drawn increasing attention, and benefits of various treatment strategies, including nutrition, medication and physical exercise, maybe microbially-mediated. Metformin is a widely used hypoglycemic agent, while resistant starch (RS) is a novel dietary fiber that emerges as a nutritional strategy for metabolic disease. However, it remains unclear as to the potential degree and interactions among gut microbial communities, metabolic landscape, and the anti-diabetic effects of metformin and RS, especially for a novel type 3 resistant starch from Canna edulis (Ce-RS3). In the present study, T2DM rats were administered metformin or Ce-RS3, and the changes in gut microbiota and serum metabolic profiles were characterized using 16S-rRNA gene sequencing and metabolomics, respectively. After 11 weeks of treatment, Ce-RS3 exhibited similar anti-diabetic effects to those of metformin, including dramatically reducing blood glucose, ameliorating the response to insulin resistance and glucose tolerance test, and relieving the pathological damage in T2DM rats. Interestingly, the microbial and systemic metabolic dysbiosis in T2DM rats was effectively modulated by both Ce-RS3 and, to a lesser extent, metformin. The two treatments increased the gut bacterial diversity, and supported the restoration of SCFA-producing bacteria, thereby significantly increasing SCFAs levels. Both treatments simultaneously corrected 16 abnormal metabolites in the metabolism of lipids and amino acids, many of which are microbiome-related. PICRUSt analysis and correlation of SCFAs levels with metabolomics data revealed a strong association between gut microbial and host metabolic changes. Strikingly, Ce-RS3 exhibited better efficacy in increasing gut microbiota diversity with a peculiar enrichment of Prevotella genera. The gut microbial properties of Ce-RS3 were tightly associated with the T2DM-related indexes, showing the potential to alleviate diabetic phenotype dysbioses, and possibly explaining the greater efficiency in improving metabolic control. The beneficial effects of metformin and Ce-RS3 might derive from changes in gut microbiota through altering host-microbiota interactions with impact on the host metabolome. Given the complementarity of metformin and Ce-RS3 in regulation of gut microbiota and metabolites, this study also prompted us to suggest possible "Drug-Dietary fiber" combinations for managing T2DM.

Abstract
NME4, also designated nm23-H4 or NDPK-D, has been known for years for its well-established roles in the synthesis of nucleoside triphosphates, though; little has been known regarding the differential metabolites involved as well as the biological roles NME4 plays in proliferation and invasion of esophageal squamous cell carcinoma (ESCC) cells. To understand the biological roles of NME4 in ESCC cells, lentiviral-based short hairpin RNA interference (shRNA) vectors were constructed and used to stably knock down NME4. Then, the proliferative and invasive variations were assessed using MTT, Colony formation and Transwell assays. To understand the metabolites involved after silencing of NME4 in ESCC cells, widely targeted metabolomic screening was taken. It was discovered that silencing of NME4 can profoundly suppress the proliferation and invasion in ESCC cells in vitro. Metabolically, a total of 11 differential metabolites were screened. KEGG analyses revealed that Tryptophan, Riboflavin, Purine, Nicotinate, lysine degradation, and Linoleic acid metabolism were also involved in addition to the well-established nucleotides metabolism. Some of these differential metabolites, say, 2-Picolinic Acid, Nicotinic Acid and Pipecolinic Acid were suggested to be associated with tumor immunomodulation. The data we described here support the idea that metabolisms occurred in mitochondrial was closely related to tumor immunity.

Abstract
Multiple sclerosis (MS) is the most common cause of neurological diseases. Although, there are some effective medications with regulatory approval for treating MS, they are only partially effective and cannot promote repairing of tissue damage directly which occurs in the central nervous system. Therefore, there is an essential need to develop novel therapeutic approaches for neuroprotection or repairing damaged tissue in MS. Accordingly, cell-based therapies as a novel therapeutic strategy have opened a new horizon in treatment of MS. Each setting in cell therapy has potential benefits. Human endometrial stem cells as an invaluable source for cell therapy have introduced treatment for MS. In this respect, good manufacturing practice (GMP) has a pivotal role in clinical production of stem cells. This chapter tries to describe the protocol of GMP-grade endometrial stem cells for treatment of MS.

Abstract
Recently, gene therapy as one of the most promising treatments can apply genes for incurable diseases treatment. In this context, vectors as gene delivery systems play a pivotal role in gene therapy procedure. Hereupon, viral vectors have been increasingly introduced as a hyper-efficient tools for gene therapy. Adenoviral vectors as one of the most common groups which are used in gene therapy have a high ability for humans. Indeed, they are not integrated into host genome. In other words, they can be adapted for direct transduction of recombinant proteins into targeted cells. Moreover, they have large packaging capacity and high levels of efficiency and expression. In accordance with translational pathways from the basic to the clinic, recombinant adenoviral vectors packaging must be managed under good manufacturing practice (GMP) principles before applying in clinical trials. Therein, in this chapter standard methods for manufacturing of GMP-compliant Adenoviral vectors for gene therapy have been introduced.

Abstract
Mesenchymal stem cells are one of the most attractive sources for stem cell research and therapy. Their safety and efficacy have been demonstrated in many clinical trials. Because of their low immunogenicity and immunomodulatory properties, allogenic MSCs have been transplanted in different clinical studies. MSCs could be in different adult- and fetal-derived tissues including pregnancy products. Placenta-derived mesenchymal stem cells (PLMSCs) that can be harvested without using any invasive procedures from a discarding tissue are one of the important types of mesenchymal stem cells for therapeutic applications. Stem cell manufacturing for therapeutic applications should be in compliance with the basic principles of good manufacturing practice (GMP). Herein, the current chapter is to describe GMP-compliant production of human PLMSCs, which are suitable for clinical applications.

SWATH-MS for metabolomics and lipidomics: critical aspects of qualitative and quantitative analysis.

Authors: Raetz M, Bonner R, Hopfgartner G
Abstract
INTRODUCTION: While liquid chromatography coupled to mass spectrometric detection in the selected reaction monitoring detection mode offers the best quantification sensitivity for omics, the number of target analytes is limited, must be predefined and specific methods developed. Data independent acquisition (DIA), including SWATH using quadrupole time of flight or orbitrap mass spectrometers and generic acquisition methods, has emerged as a powerful alternative technique for quantitative and qualitative analyses since it can cover a wide range of analytes without predefinition.
OBJECTIVES: Here we review the current state of DIA, SWATH-MS and highlight novel acquisition strategies for metabolomics and lipidomics and opportunities for data analysis tools.
METHOD: Different databases were searched for papers that report developments and applications of DIA and in particular SWATH-MS in metabolomics and lipidomics.
RESULTS: DIA methods generate digital sample records that can be mined retrospectively as further knowledge is gained and, with standardized acquisition schemes, used in multiple studies. The different chemical spaces of metabolites and lipids require different specificities, hence different acquisition and data processing approaches must be considered for their analysis.
CONCLUSIONS: Although the hardware and acquisition modes are well defined for SWATH-MS, a major challenge for routine use remains the lack of appropriate software tools capable of handling large datasets and large numbers of analytes.
