Metabolomic changes during active immunization with anti-METH vaccines.

ABSTRACT: A targeted metabolomics analysis was performed on serum samples from rats immunized with a methamphetamine-like hapten covalently bound to keyhole limpet hemocyanin (KLH) monomers, and controls. The subjects were approximately 300 g adult male Sprague Dawley rats. RTI International RCMRC received pre-immune serum from RI 11-03A (n=12) which is a matched control serum that was collected before starting immunizations, and week 17 bleeds from RI 11-03A (n=12), RI 11-03B (n=8), and RI 11-03C (n=12). The A-C nomenclature denotes A) complete antigen with adjuvant, B) complete antigen without adjuvant and C) only KLH carrier protein and adjuvant without a METH-like hapten. The rats’ serum samples were extracted and prepared for a combined flow injection (FIA) and LC-MS/MS assay (Biocrates AbsoluteIDQ® p180 kit). The Biocrates AbsoluteIDQ® p180 kit (Biocrates Life Sciences AG, Innsbruck, Austria) can quantitatively measure ~188 biologically relevant metabolites from five analyte groups (acylcarnitines, amino acids, biogenic amines, glycerophospho- and sphingolipids, and hexoses) on a triple quadrupole mass spectrometer.

Distinct lipid signatures are identified in the plasma of rats with chronic inflammation induced by estradiol benzoate and sex hormones

Project description:INTRODUCTION: Prostatitis is likely to occur in younger or middle-aged men, while prostate cancer is likely to occur in older men. Although amino acids and lipids as biomarkers of prostate cancer have been examined using prostate cancer cell lines/tissues, no previous studies have evaluated amino acids or lipids as potential chronic prostatitis biomarkers.OBJECTIVES: The study's aim was to identify amino acids and lipids that could serve as potential biomarkers of chronic prostatitis.METHODS: We profiled the amino acids and lipids found in plasma from rats collected in a previous study. In brief, a total of 148 Sprague-Dawley rats (offspring) were dosed with estradiol benzoate (EB) on postnatal days (PNDs) 1, 3 and 5, and subsequently dosed with testosterone (T)/estradiol (E) tubes via subcutaneous implants from PND 90 to 200. Plasma was collected on PNDs 30, 90, 100, 145 and 200. Analysis was conducted with a Xevo TQ-S triple-quadrupole mass spectrometer using a Biocrates AbsoluteIDQ p180 kit.RESULTS: Plasma acylcarnitines [(C2, C16:1, C18, C18:1, C18:1-OH, and C18:2)], glycerophospholipids (lysophosphatidylcholine-acyl, -di-acyl, and -di-acyl acyl-alkyl) and sphingomyelins [SM (OH) C16:1, SM C18:0, SM C18:1, and SM C20:2] significantly increased on PND 145, when chronic inflammation was observed in the dorsolateral prostate of rats dosed with EB, T, and E. No statistical significances of amino acid levels were observed in the EB + T + E group on PND 145.CONCLUSION: Exposure to EB, T, and E altered lipid levels in rat plasma with chronic prostate inflammation. These findings suggest that the identified lipids may be predictive chronic prostatitis biomarkers. The results require confirmation through additional nonclinical and human studies.

A novel adjuvant formulation induces robust Th1/Th17 memory and mucosal recall responses in Non-Human Primates

Project description:After clean drinking water, vaccination is the most impactful global health intervention. However, development of new vaccines against difficult-to-target diseases is hampered by the lack of diverse adjuvants for human use. Of particular interest, none of the currently available adjuvants induce Th17 cells. Here, we develop and test an improved liposomal adjuvant, termed CAF®10b, that incorporates a TLR-9 agonist. In a head-to-head study in non-human primates (NHPs), immunization with antigen adjuvanted with CAF®10b induced significantly increased antibody and cellular immune responses compared to previous CAF® adjuvants, already in clinical trials. This was not seen in the mouse model, demonstrating that adjuvant effects can be highly species specific. Importantly, intramuscular immunization of NHPs with CAF®10b induced robust Th17 responses that were observed in circulation half a year after vaccination. Furthermore, subsequent instillation of unadjuvanted antigen into the skin and lungs of these memory animals led to significant recall responses including transient local lung inflammation observed by Positron Emission Tomography-Computed Tomography (PET-CT), elevated antibody titers, and expanded systemic and local Th1 and Th17 responses, including >20% antigen-specific T cells in the bronchoalveolar lavage. Overall, CAF®10b demonstrated an adjuvant able to drive true memory antibody, Th1 and Th17 vaccine-responses across rodent and primate species, supporting its translational potential.

Serum is preferable to plasma for circulating exosomal microRNA biomarker discovery studies

Project description:Exosomes were purified from 250 ul matched plasma and serum samples using ExoQuickTm. The presence of particles consistent in size with exosomes (60-150nm) was confirmed using a Nanosight LM10. miRNA was extracted from exosomes using an miRNeasy Serum/Plasma kit (Qiagen, #217184). miRNA was reversed transcribed using a TaqMan® microRNA Reverse Transcription Kit (Life technologies, #4366596). miRNA profiling was performed with a high throughput TaqMan® OpenArray® Human microRNA panel (Life technologies, #4461104). The panel consisted of probes for 754 human miRNAs that are based on miRNA sequences derived from Sanger miRBase v14. MegaplexTM Primer Human Pool A v2.1 and Human Pool B v2.0 or v3.0

Extraction of Entamoeba histolytica membrane proteins using three extraction methods

Project description:Entamoeba histolytica membrane proteins are important players in the parasite’s pathogenicity. However, most of the proteins have not been identified. This study reports the membrane proteins extracted using three extractions methods: two commercial kits (ProteoExtract® from Calbiochem and ProteoPrep® from Sigma), and a conventional laboratory method. The resulting membrane fractions (MF) and cytosolic fractions (CF)were analysed using LC-ESI-MS/MS. The proteins identified in at least two out of three biological replicates revealed a total of 490, 492, and 587 MF proteins extracted using the ProteoExtract® kit, ProteoPrep® kit and conventional method, respectively. Meanwhile, 487, 611 and 343 proteins were identified in the CF extracted using the ProteoExtract® kit, ProteoPrep® kit and conventional method, respectively. Analysis of the identified MF and CF proteins extracted by the respective extraction kits suggests that the ProteoPrep® extraction kit was the most selective in separating MF and CF among the three extraction methods.

Prolactin-induced protein (PIP) regulates proliferation of luminal A type breast cancer cells in a hormone-independent manner

Project description:RNA was extracted from cells using Aurum Total RNA kit from Bio-Rad Laboratories, Inc., Hercules, CA following the manufacturer’s recommendations. Gene expression profiling was performed using the BeadChip HumanHT-12 v4 Expression kit from Illumina®, which contains 47,231 gene-probes (Illumina® Inc., San Diego, CA). The raw signal intensities were imported and analyzed using the GenomeStudio® data software. After background subtraction and normalization, the signal intensity values were exported to the Partek® genomics expression analysis suite using “Partek's Report Plug-in” option in the GenomeStudio® software. Differentially expressed genes in the dox- versus vehicle-treated samples were identified using the “gene expression” workflow in the Partek® software.
