He W, Berthiaume JM, Previs S, Kasumov T, Zhang GF. Ischemia promotes acyl-CoAs dephosphorylation and propionyl-CoA accumulation. Metabolomics 2023; 19:12.

Abstract
INTRODUCTION Our untargeted metabolic data unveiled that Acyl-CoAs undergo dephosphorylation, however little is known about these novel metabolites and their physiology/pathology relevance. OBJECTIVES To understand the relationship between acyl-CoAs dephosphorylation and energy status as implied in our previous work, we seek to investigate how ischemia (energy depletion) triggers metabolic changes, specifically acyl-CoAs dephosphorylation in this work. METHODS Rat hearts were isolated and perfused in Langendorff mode for 15 min followed by 0, 5, 15, and 30 minutes of global ischemia. The heart tissues were harvested for metabolic analysis. RESULTS As expected, ATP and phosphocreatine were significantly decreased during ischemia. Most short- and medium-chain acyl-CoAs progressively increased with ischemic time from 0 to 15 min, whereas a 30-minute ischemia did not lead to further change. Unlike other acyl-CoAs, propionyl-CoA accumulated progressively in the hearts that underwent ischemia from 0 to 30 min. Progressive dephosphorylation occurred to all assayed acyl-CoAs and free CoA regardless their level changes during the ischemia. CONCLUSION The present work further confirms that dephosphorylation of acyl-CoAs is an energy-dependent process and how this dephosphorylation is mediated warrants further investigations. It is plausible that dephosphorylation of acyl-CoAs and limited anaplerosis are involved in ischemic injuries to heart. Further investigations are warranted to examine the mechanisms of acyl-CoA dephosphorylation and how the dephosphorylation is possibly involved in ischemic injuries.

Sensitivity Detection of Uric Acid and Creatinine in Human Urine Based on Nanoporous Gold. BIOSENSORS 2022; 12:bios12080588. [PMID: 36004983 PMCID: PMC9405689 DOI: 10.3390/bios12080588] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 07/25/2022] [Accepted: 07/27/2022] [Indexed: 11/17/2022]
Abstract
Given the significance of uric acid and creatinine in clinical diagnostic, disease prevention and treatment, a multifunctional electrochemical sensor was proposed for sensitive detection of uric acid and creatinine. The sensitive detection of uric acid was realized based on the unique electrochemical oxidation of nanoporous gold (NPG) towards uric acid, showing good linearity from 10 μM to 750 μM with a satisfactory sensitivity of 222.91 μA mM−1 cm−2 and a limit of detection (LOD) of 0.06 μM. Based on the Jaffé reaction between creatinine and picric acid, the sensitive detection of creatinine was indirectly achieved in a range from 10 to 2000 μM by determining the consumption of picric acid in the Jaffé reaction with a detection sensitivity of 195.05 μA mM−1 cm−2 and a LOD of 10 μM. For human urine detection using the proposed electrochemical sensor, the uric acid detection results were comparable to that of high-performance liquid chromatography (HPLC), with a deviation rate of less than 10.28% and the recoveries of uric acid spiked in urine samples were 89~118%. Compared with HPLC results, the deviation rate of creatinine detection in urine samples was less than 4.17% and the recoveries of creatinine spiked in urine samples ranged from 92.50% to 117.40%. The multifunctional electrochemical sensor exhibited many advantages in practical applications, including short detection time, high stability, simple operation, strong anti-interference ability, cost-effectiveness, and easy fabrication, which provided a promising alternative for urine analysis in clinical diagnosis.

Abstract
Pathogen recognition and the triggering of host innate immune system are critical to understanding pathogen-host interaction. Cellular surveillance systems have been identified as an important strategy for the identification of microbial infection. In the present study, using Bacillus thuringiensis-Caenorhabditis elegans as a model, we found an approach for surveillance systems to sense pathogens. We report that Bacillus thuringiensis Cry5Ba, a typical pore-forming toxin, caused mitochondrial damage and energy imbalance by triggering potassium ion leakage, instead of directly targeting mitochondria. Interestingly, we find C. elegans can monitor intracellular energy status to trigger innate immune responses via AMP-activated protein kinase (AMPK), secreting multiple effectors to defend against pathogenic attacks. Our study indicates that the imbalance of energy status is a prevalent side effect of pathogen infection. Furthermore, the AMPK-dependent surveillance system may serve as a practicable strategy for the host to recognize and defense against pathogens. Bacillus thuringiensis toxin Cry5Ba triggers potassium ion leakage, causing mitochondrial damage and energy imbalance. C. elegans can monitor this intracellular energy imbalance via AMP-activated protein kinase to trigger innate immune responses.

Abstract
Cyclocreatine and its water-soluble derivative, cyclocreatine phosphate (CCrP), are potent cardioprotective drugs. Based on recent animal studies, CCrP, FDA-awarded Orphan Drug Designation, has a promising role in increasing the success rate of patients undergoing heart transplantation surgery by preserving donor hearts during transportation and improving the recovery of transplanted hearts in recipient patients. In addition, CCrP is under investigation as a promising treatment for creatine transporter deficiency, an X-linked inborn error resulting in a poor quality of life for both the patients and the caregiver. A newly designed molecularly imprinted polymer (MIP) material was fabricated by the anodic electropolymerization of o-phenylenediamine on screen-printed carbon electrodes and was successfully applied as an impedimetric sensor for CCrP determination to dramatically reduce the analysis time during both the clinical trial phases and drug development process. To enhance the overall performance of the proposed sensor, studies were performed to optimize the electropolymerization conditions, incubation time, and pH of the background electrolyte. Scanning electron microscopy, electrochemical impedance spectroscopy, and cyclic voltammetry were used to characterize the behavior of the developed ultrathin MIP membrane. The CCrP-imprinted polymer has a high recognition affinity for the template molecule because of the formation of 3D complementary cavities within the polymer. The developed MIP impedimetric sensor had good linearity, repeatability, reproducibility, and stability within the linear concentration range of 1 × 10-9 to 1 × 10-7 mol/L, with a low limit of detection down to 2.47 × 10-10 mol/L. To verify the applicability of the proposed sensor, it was used to quantify CCrP in spiked plasma samples.

Abstract
Nucleotides, which are important low-molecular-weight compounds present in organisms, are precursors of nucleic acids and participate in various regulatory and metabolic functions. Sensitive and valid methods for monitoring and determining nucleotides and nucleosides in different samples are urgently required. Due to the presence of numerous endogenous interferences in complex matrices and the high polarity of the molecules of the phosphate moiety, the determination of nucleotide content is challenging. This review summarizes the pretreatment and analysis methods of nucleotides in different samples. Advanced pretreatment methods, including different microextraction methods, solid-phase extraction based on novel materials, QuEChERS, are clearly displayed, and continuous progress which has been made in LC, LC-MS/MS and capillary electrophoresis methods are discussed. Moreover, the strengths and weaknesses of different methods are discussed and compared. Highlight:Advanced pretreatment and detection methods of nucleotides were critically reviewed.Microextraction technology was one of the trends of nucleotides pretreatment in the future.Applications of novel materials and supercritical fluid were highlighted.The evolution and advance of HRMS analyzers were in detailed.

Abstract
Purinergic signalling is involved in physiological processes, particularly during ischemia-reperfusion injuries for which it has a protective effect. The purpose of this work was to develop a method for simultaneous quantification of eight nucleotides and adenosine in biological matrices by liquid chromatography coupled with high-resolution mass spectrometry. A method was developed that was sufficiently robust to quantify the targeted analytes in 20 min with good sensitivity. Analysis of extracellular media from cultured endothelial cells detected the release of nucleotides and adenosine during 2 h of hypoxia. The quantification of cylic adenosine monophosphate (cAMP) allowed to establish a dose-response curve after receptor stimulation. Therefore, our method allows us to study the involvement of nucleotides in various processes in both the intracellular and extracellular compartment.

Abstract
A high-performance liquid chromatography (HPLC) method with UV detection was established and validated for the simultaneous determination of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) in mouse myocardial tissues. After protein precipitation and compound extraction with pre-cooled perchloric acid and the supernatant was centrifuged with the pH value adjusted to 6.5-7.5, the analytes were separated on a porous graphitic carbon LC column (4.6 mm × 100 mm, 5 μm) using gradient elution with a mobile phase of 10 mmol/L borax solution, pH 9.18(A) and acetonitrile-tetrahydrofuran (1:1, v/v) (B). The LC flow rate was 0.8 mL/min; the UV detection wavelength was 254 nm and the column temperature was maintained at 35 °C. ATP, ADP, and AMP were separated and the intra-day relative standard deviations (RSDs) of peak area repeatability were 1.3-2.5% (n = 6). The correlation coefficients of the linearity between UV responses and adenosine phosphate concentrations were larger than 0.9998 in all cases, within concentration ranges of 0.71-91.6 μg/mL for ATP, 1.3-81.5 μg/mL for ADP and 1.69-108.1 μg/mL for AMP. The limits of detection were within 0.17-0.21 μg/mL. The average standard substance spiked-in recoveries were 93.6-104.7% (n = 3). The established HPLC method was successfully applied to quantitate ATP, ADP, and AMP in mouse myocardial tissues.

Abstract
Creatine transporter deficiency (CTD) is caused by a defect in the X-linked creatine transporter SLC6A8 gene leading to severe neurologic and physiologic conditions. Cyclocreatine and phosphocyclocreatine supplementation is seen as a potential treatment, but the presence of these compounds within commercially available dietary supplements presents the risk of self-medication. High-performance liquid chromatography-mass spectrometry (HPLC-MS) is an excellent technique to assess composition of complex amino acid mixtures. Herein, we have developed a facile HPLC-MS method using a cyano column in hydrophilic interaction liquid chromatography (HILIC) mode with isocratic elution over 4 min to identify the main components of two commercially available dietary supplements. The relative standard deviation (RSD) for retention time and extracted ion integrated area are <0.3% and 4%, respectively, showing excellent reproducibility. Cyclocreatine and phosphocyclocreatine were not detectable within the dietary supplements, even at ppm levels, demonstrating the power and importance of the developed HPLC-MS method in analyzing complex mixtures.

Abstract
A simple and rapid HPLC-MS/MS method was developed and validated for simultaneous measurement of phosphocreatine and its metabolites creatine and creatinine in children's plasma. A 50 μL aliquot of plasma was prepared by protein precipitation with acetonitrile-water (1000 μL, 1:1, v/v) followed by separation on a Hypersil Gold C18 column (35°C) with gradient mobile phase consisting of 2 mm ammonium acetate aqueous solution (pH 10) and methanol at a flow rate of 0.3 mL/min and analyzed by mass spectrometry in both positive (phosphocreatine) and negative (creatine and creatinine) ion multiple reaction monitoring mode. Good linearity (r > 0.99) was obtained for the three analytes. The intra-day and inter-day values of CV were <5.46% (-13.09% ≤ RE ≤ 2.57%). The average recoveries of the three analytes were 70.9-97.5%. No obvious impact was found for the quantitation of three analytes in normal, hemolyzed and hyperlipemic plasma. In the end, this method was successfully applied to a pharmacokinetic study of phosphocreatine in children (six cases) with viral myocarditis of children after intravenous infusion of 2 g of the test drug. The pharmacokinetc parameters of phosphocreatine/creatine were as follows: t1/2 0.24/0.83 h, Tmax 0.49/0.55 h, Cmax 47.34/59.29 μg/mL, AUClast 17.07/59.63 h μg/mL, AUCinf 17.16/79.01 h μg/mL and MRT 0.29/0.67 h.

Hydrophilic interaction chromatography coupled to tandem mass spectrometry as a method for simultaneous determination of guanidinoacetate and creatine. Anal Chim Acta 2018; 1028:96-103.

Abstract
The biosynthesis of creatine (Cr) is closely related to the bioavailability of guanidinoacetate (GAA). The lack of one or the other may compromise their role in the energy transport and cell signaling. A reliable estimate of their levels in biological samples is imperative since they are important markers of many metabolic disorders. Therefore, a new LC-MS/MS method for simultaneous determination and quantification of GAA and Cr by multiple reaction monitoring (MRM) mode was developed based on the hydrophilic interaction chromatography (HILIC) and response surface methodology (RSM) for the optimization of chromatographic parameters. The optimized parameters ensured good separation of these similar, very polar molecules (chromatographic resolution > 1.5) without prior derivatization step in a short analysis run (6 min). The developed method was validated to ensure accurate (R, 75.1-101.6%), precise (RSD < 20%) and low quantification (LOQ of 0.025 μg mL-1 for GAA and 0.006 μg mL-1 for Cr) of the tested analytes and the use of matrix-matched calibration eliminated variable effects of complex matrices such as human plasma and urine. Therefore, this method can be implemented in medical laboratories as a tool for the diagnostics of creatine deficiencies and monitoring of guanidinoacetate and creatine supplementation regimes in biological samples.

Abstract
Nucleotides play a role in inflammation processes: cAMP and cGMP in the endothelial barrier function, ADP in platelet aggregation, ATP and UTP in vasodilatation and/or vasoconstriction of blood vessels, UDP in macrophages activation. The aim of this study is to develop and validate a LC/MS-MS method able to quantify simultaneously nine nucleotides (AMP, cAMP, ADP, ATP, GMP, cGMP, UMP, UDP and UTP) in biological matrixes (cells and plasma). The method we developed, has lower LOQ's than others and has the main advantage to quantify all nucleotides within one single injection in less than 10 min. The measured nucleotides concentrations obtained with this method are similar to those obtained with assay kits commercially available. Analysis of plasma and red blood cells from healthy donors permits to estimate the physiological concentration of those nucleotides in human plasma and red blood cells, such information being poorly available in the literature. Furthermore, the protocol presented in this paper allowed us to observe that AMP, ADP, ATP concentrations are modified in human red blood cells and plasma after a venous stasis of 4 min compared to physiological blood circulation. Therefore, this specific method enables future studies on nucleotides implications in chronic inflammatory diseases but also in other pathologies where nucleotides are implicated in.

Qin X, Wang X. Quantification of nucleotides and their sugar conjugates in biological samples: Purposes, instruments and applications. J Pharm Biomed Anal 2018; 158:280-287.

Abstract
Nucleotides and their sugar conjugates are fundamental molecules in life, participating in processes of DNA/RNA composition, cell wall build-up, glycosylation reactions, and signal conduction. Therefore, the quantification of these compounds in biological samples significantly benefits the understanding of their functions. However, nucleotides and nucleotide sugars are extremely hydrophilic, causing bad retention and peak symmetry on regular C18 chromatographic columns. To solve this problem, ion-pair (IP) chromatography, ion-exchange (IE) chromatography and hydrophilic interaction chromatography (HILIC) were applied, of which differentiated mechanisms were utilized to increase the retention of the analytes on the stationary phases. IP-HPLC and HILIC were convenient for coupling with many kinds of detectors (ultraviolet, UV or mass spectrometry, MS). Combining these two kinds of techniques, the advantages of better separation and retention were increased, while disadvantages like irreversible adsorption by stationary phases were greatly decreased. Due to the high concentrations of nonvolatile buffer salts used, IE-HPLC was not suitable for MS detectors. Protein precipitation and solid phase extraction were the common methods for sample treatment in the analysis of nucleotides and nucleotide sugars. By carefully optimizing the LCUV or LCMS conditions, high sensitivities could be achieved, and the methods could be applied to the analysis of many kinds of biological samples (cells, tissues, plants, bacteria, etc.). Developing new analyzing techniques may help the utilization of nucleotides and nucleotide sugars in the diagnosis and therapy of diseases.

J Pharm Biomed Anal 2017; 145:629-633. [PMID: 28800523 DOI: 10.1016/j.jpba.2017.07.049] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2017] [Revised: 07/27/2017] [Accepted: 07/30/2017] [Indexed: 01/09/2023]
Abstract
An accurate, rapid and selective method was developed to quantify cyclocreatine in mouse and rat plasma using hydrophilic interaction (HILIC) ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The plasma samples were prepared by protein precipitation with acetonitrile:methanol (70:30). Chromatographic separation was performed on a HILIC BEH amide column (2.1mm×50mm, 1.7μm) with a 3min gradient elution at a flow rate of 0.5mL/min. For mass spectrometric detection, selected reaction monitoring (SRM) was used; the SRM transitions were m/z 144→98 and m/z 144→56 for cyclocreatine and m/z 148→102 for the internal standard (D4-cyclocreatine) in the positive ionization mode. No endogenous components interfered with the analysis of cyclocreatine and the internal standard in mouse and rat plasma. Plasma calibration curves were constructed in the range of 0.01-25μM. The correlation coefficient of the calibration curves was greater than 0.99. The mean intraday assay accuracy for all quality control (QC) replicates was between 93 and 105%. The mean intraday assay precision (CV%) was 1.9-11% for all QC levels. The HILIC-UPLC-MS/MS method was successfully applied in pharmacokinetic (PK) studies of cyclocreatine in mice and rats for the first time. After a single 30mg/kg oral administration in mice and rats, the AUC0-∞ (area under the curve) was 84.1μgh/mL and 91.7±18.0μgh/mL, respectively.

A sensitive method for the separation and quantification of low-level adenine nucleotides using porous graphitic carbon-based liquid chromatography and tandem mass spectrometry. J Chromatogr B Analyt Technol Biomed Life Sci 2017; 1061-1062:445-451.

Abstract
A liquid chromatography coupled to heated electrospray ionization/tandem mass spectrometry (LC-HESI-MS/MS) method was developed for the simultaneous quantitative analysis of low nanomolar level adenine nucleotides AMP, ADP, ATP, cyclic AMP (cAMP), and the nucleoside adenosine. For analyte retention and separation, reverse phase chromatography using porous graphitic carbon (PGC) was employed as it provided full resolution. The erratic chromatographic behaviour characteristic of PGC, including deterioration of analyte resolution and increased peak tailing (leading to decreased sensitivity), was mitigated by incorporating acidic equilibration within runs using a quaternary gradient. Analyte resolution and chromatographic sensitivity were still lost after a period of column inactivity; hence a pre-conditioning protocol was implemented between batches to regenerate the column. These column regeneration measures also allowed elution of AMP, ADP and ATP in the sequence of mono- to tri- nucleotides, differing from conventional reverse phase elution where analytes elute with decreasing polarity. This nucleotide elution sequence has the advantage of overcoming potential mis-annotation and inaccurate quantification of smaller nucleotides caused by in-source fragmentation of ATP. The method was validated in granulosa cell conditioned media, with the LLOQs ranging between 10-50nM for most analytes. To verify the method using biological samples, nucleotide secretion was measured in granulosa cell conditioned media under various treatments known to alter their levels. Moreover, the method was applied to cumulus-oocyte complex cell lysates to examine its linearity in a complex matrix.

Abstract
BACKGROUND Creatine phosphate (CrP) plays a fundamental physiological role by providing chemical energy for cell viability and activity, especially in muscle tissue. Numerous pathological conditions, caused by acute or chronic ischaemic situations, are related to its deficiency. For these reasons, it has been used as a cardioprotective agent in heart surgery and medical cardiology for many years. OBJECTIVE This article gives a brief overview of the main characteristics of exogenous CrP. METHODS Previous review articles on CrP were screened for relevant information and references. Results from selected studies were reviewed and classified according to the topics in this review article and provided further interesting information on the pharmacological role of this molecule. RESULTS Besides CrP's well known cell energy and function restoring properties, new evidence is emerging regarding its antioxidant and anti-apoptotic properties. Use of CrP is well established clinically as an intraoperative and perioperative adjuvant in heart operations (valve replacement, coronary artery bypass grafting, congenital heart defect repair), and as an additional agent in medical cardiology therapy for acute myocardial infarction and acute and chronic heart failure. In particular, there are promising potential new CrP uses in neurology, such as in cerebral ischaemia and hypoxic ischaemic encephalopathy. CONCLUSIONS This review article describes the role of CrP treatment in cardiological indications, such as cardioprotection in cardioplegia and in myocardiopathies of various etiopathogenesis, as well as in other clinical indications such as skeletal muscle rehabilitation and neurological conditions.

Abstract
The continuous administration of compound danshen dripping pills (CDDP) showed good efficacy in relieving myocardial ischemia clinically. To probe the underlying mechanism, metabolic features were evaluated in a rat model of acute myocardial ischemia induced by isoproterenol (ISO) and administrated with CDDP using a metabolomics platform. Our data revealed that the ISO-induced animal model showed obvious myocardial injury, decreased energy production, and a marked change in metabolomic patterns in plasma and heart tissue. CDDP pretreatment increased energy production, ameliorated biochemical indices, modulated the changes and metabolomic pattern induced by ISO, especially in heart tissue. For the first time, we found that ISO induced myocardial ischemia was accomplished with a reduced fatty acids metabolism and an elevated glycolysis for energy supply upon the ischemic stress; while CDDP pretreatment prevented the tendency induced by ISO and enhanced a metabolic shift towards fatty acids metabolism that conventionally dominates energy supply to cardiac muscle cells. These data suggested that the underlying mechanism of CDDP involved regulating the dominant energy production mode and enhancing a metabolic shift toward fatty acids metabolism in ischemic heart. It was further indicated that CDDP had the potential to prevent myocardial ischemia in clinic.

Evaluation of umami taste in mushroom extracts by chemical analysis, sensory evaluation, and an electronic tongue system. Food Chem 2015; 192:1068-77.

Abstract
Seventeen edible mushrooms commercially available in Korea were analysed for their umami taste compounds (5'-nucleotides: AMP, GMP, IMP, UMP, XMP; free amino acids: aspartic, glutamic acid) and subjected to human sensory evaluation and electronic tongue measurements. Amanita virgineoides featured the highest total 5'-nucleotide content (36.9 ± 1.50 mg/g), while monosodium glutamate-like components (42.4 ± 6.90 mg/g) were highest in Agaricus bisporus. The equivalent umami concentration (EUC) ranged from 1.51 ± 0.42 to 3890 ± 833 mg MSG/g dry weight; most mushrooms exhibited a high umami taste. Pleurotus ostreatus scored the highest in the human sensory evaluation, while Flammulina velutipes obtained the maximum score in the electronic tongue measurement. The EUC and the sensory score from the electronic tongue test were highly correlated, and also showed significant correlation with the human sensory evaluation score. These results suggest that the electronic tongue is suitable to determine the characteristic umami taste of mushrooms.
