Abstract
We developed a new procedure for the comprehensive analysis of metabolites and enzymes involved in polyamine metabolism pathways. The procedure utilizes stable isotope-labeled polyamines and directly and precisely determines labeled products from enzymatic reactions by ESI-Q-TOF-MS. The activity of different enzymes could be determined in essentially the same manner by suitably adjusting the reaction conditions for each individual enzyme. We applied the procedure to extracts of regenerating rat liver and analyzed the changes in polyamine-metabolizing enzymes and polyamine contents during recovery from partial hepatectomy. A general outline of polyamine metabolism and information of polyamine dynamics were obtained. This kind of comprehensive information would be valuable in unifying detailed but fragmentary information obtained through conventional analyses focusing on one or a few enzymes and on a limited aspect of polyamine metabolic pathway.

Gender-Related Differences on Polyamine Metabolome in Liquid Biopsies by a Simple and Sensitive Two-Step Liquid-Liquid Extraction and LC-MS/MS. Biomolecules 2019; 9:biom9120779. [PMID: 31779105 PMCID: PMC6995533 DOI: 10.3390/biom9120779] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 11/13/2019] [Accepted: 11/21/2019] [Indexed: 01/15/2023] Open
Abstract
Polyamines are involved in the regulation of many cellular functions and are promising biomarkers of numerous physiological conditions. Since the concentrations of these compounds in biological fluids are low, sample extraction is one of the most critical steps of their analysis. Here, we developed a comprehensive, sensitive, robust, and high-throughput LC-MS/MS stable-isotope dilution method for the simultaneous determination of 19 metabolites related to polyamine metabolism, including polyamines, acetylated and diacetylated polyamines, precursors, and catabolites from liquid biopsies. The sample extraction was optimized to remove interfering compounds and to reduce matrix effects, thus being useful for large clinical studies. The method consists of two-step liquid-liquid extraction with a Folch extraction and ethyl acetate partitioning combined with dansyl chloride derivatization. The developed method was applied to a small gender-related trial concerning human serum and urine samples from 40 obese subjects. Sex differences were found for cadaverine, putrescine, 1,3-diaminopropane, γ-aminobutyric acid, N8-acetylspermidine, and N-acetylcadaverine in urine; N1-acetylspermine in serum; and spermine in both serum and urine. The results demonstrate that the developed method can be used to analyze biological samples for the study of polyamine metabolism and its association with human diseases.

Abstract
As an important biomarker for cancer, polyamine levels in body fluid could be employed for monitoring the colorectal cancer (CRC), however the role of polyamines in the development and therapeutics phases of CRC remains uncertain. In this paper, the relationship between polyamines and CRC development and therapeutics had been investigated by the study of changes in plasma polyamine levels during the precancerous, developmental and treatment phases of CRC. After inducing CRC in Wistar rats by intraperitoneal injection of 1, 2-dimethylhydrazine, the animals were given a traditional Chinese medicine, Aidi injections. Firstly, the polyamine levels in the plasma of CRC, healthy and medicated rats were measured by UHPLC-MS/MS assay. In addition, Lasso regression analysis was used for screening and confirming the key markers, which can be employed for distinguishing the healthy and CRC rats as well as the CRC and medication rats. The results obtained showed that polyamine metabolism had been disrupted by CRC but returned to normal levels following Aidi injections and, in particular, putrescine and agmatine were closely correlated with CRC. Our results demonstrate the potential value of plasma polyamine metabolic profiling during the early diagnosis and medical treatment of CRC. Also, the integrated method of polyamine metabolite target analysis and lasso regression analysis can be applied in metabolomics for seeking the differential metabolites.

Abstract
A novel methodology for the determination of ornithine, putrescine, cadaverine, spermidine and gamma-amino butyric acid in urine samples has been developed. The method uses in situ aqueous derivatization followed by automated microextraction by packed sorbent coupled to a gas chromatography-mass spectrometry system equipped with a programmed temperature vaporizer. This instrumental configuration minimizes sample manipulation due to from the mixing of the reagents, the process is completely automated. The analytes were derivatized using ethyl chloroformate as derivatization reagent. The reaction occurred in aqueous medium and was carried out in 1min in the vial of an autosampler used to perform microextraction by packed sorbent. The parameters affecting derivatization, extraction and separation were optimized in order to obtain maximum sensitivity. Calibration curves were obtained for five calibration levels in three different matrices. All the calibration models displayed good linearity, with R(2) values higher than 0.95. The validity of the models was checked using ANOVA, and it was observed that they did not exhibit any lack of fit. Repeatability and reproducibility was evaluated, with values below 15% in both cases. LOD and LOQ values were found to be in the low μg/L level. Influence of the matrix was confirmed, thus quantification was performed using the standard additions method and normalization to IS. The method developed was applied to the analysis of these compounds in urine samples from healthy individuals and cancer diagnosed patients (Internal Medicine Unit of the Virgen de la Vega Hospital, Salamanca, Spain). Significant differences (Mann-Whitney U test) were observed for putrescine and ornithine concentrations.

Abstract
BACKGROUND Early detection of non-small-cell lung cancer (NSCLC) and accurate prognostic risk assessment could improve patient outcome. We examined the significance of urinary N(1), N(12)-diacetylspermine (DiAcSpm) in the detection and prognostic stratification of NSCLC patients. METHODS A DiAcSpm/cutoff ratio (DASr) was established for 260 NSCLC patients, 99 benign lung disease patients, and 140 healthy volunteers, using colloidal gold aggregation methods. The DASr was compared between patients and healthy controls, and the prognostic significance of DASr was examined. RESULTS The median urinary DASr of NSCLC patients was significantly higher than that of healthy controls (0.810 vs 0.534, P<0.001). The DASr was higher in squamous cell carcinoma (SqCC) patients than in adenocarcinoma patients (1.18 vs 0.756, respectively, P=0.039). An increased urinary DASr value was significantly associated with pathological stage, other histological invasive factors and unfavourable outcomes in patients with completely resected NSCLC. Multivariate Cox regression analysis showed that increased urinary DASr was an independent prognostic factor (hazard ratio=4.652, 95% confidence interval (CI), 2.092-10.35; P<0.001). CONCLUSIONS Urinary DASr was significantly increased in NSCLC, especially in SqCC. Urinary DASr was an independent poor prognostic indicator in patients with completely resected NSCLC. The DASr could be a useful biomarker for detecting malignancies and predicting prognosis.

Abstract
PURPOSE We have investigated the potential of metabolomics to discover blood-based biomarkers relevant to lung cancer screening and early detection. An untargeted metabolomics approach was applied to identify biomarker candidates using prediagnostic sera from the Beta-Carotene and Retinol Efficacy Trial (CARET) study. PATIENTS AND METHODS A liquid chromatography/mass spectrometry hydrophilic interaction method designed to profile a wide range of metabolites was applied to prediagnostic serum samples from CARET participants (current or former heavy smokers), consisting of 100 patients who subsequently developed non-small-cell lung cancer (NSCLC) and 199 matched controls. A separate aliquot was used to quantify levels of pro-surfactant protein B (pro-SFTPB), a previously established protein biomarker for NSCLC. On the basis of the results from the discovery set, blinded validation of a metabolite, identified as N(1),N(12)-diacetylspermine (DAS), and pro-SFTPB was performed using an independent set of CARET prediagnostic sera from 108 patients with NSCLC and 216 matched controls. RESULTS Serum DAS was elevated by 1.9-fold, demonstrating significant specificity and sensitivity in the discovery set for samples collected up to 6 months before diagnosis of NSCLC. In addition, DAS significantly complemented performance of pro-SFTPB in both the discovery and validations sets, with a combined area under the curve in the validation set of 0.808 (P < .001 v pro-SFTPB). CONCLUSION DAS is a novel serum metabolite with significant performance in prediagnostic NSCLC and has additive performance with pro-SFTPB.

Abstract
Polyamines and their N-acetylated metabolites are potential biomarkers in the diagnosis and therapeutic evaluation of cancer. Thus, we present here an ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for the simultaneous determination of 6 free, 3 monoacetylated, and 2 diacetylated polyamines without derivatization. The major improvement of this method is the use of 0.2 % perfluoroheptanoic acid methanol in the pretreatment step to achieve protein precipitation and 0.0125 % perfluoroheptanoic acid in the mobile phase to achieve analyte separation within 9 min. The established analytical method was validated with plasma, urine, and liver tissue and applied to determine plasma, urine, and liver tissue samples from healthy rats, hepatocellular carcinoma rats, and administrated rats successfully. Results indicated free polyamines such as putrescine mainly existed in liver tissue but more polar N-acetylated metabolites such as N (1),N (12)-diacetylspermine seemed to exist in biological fluid. After carcinogenesis, the levels of polyamines were increased, but the elevated levels of polyamines and their metabolites tended to decrease when administrated with anticancer drug. The method provided a more versatile manner for clinical application in the diagnosis and therapeutic evaluation of hepatocellular carcinoma.

Abstract
Background To select optimal candidates for limited lung resection, it is necessary to accurately differentiate the non-invasive tumors from other small-sized lung cancer. Urinary N1, N12-diacetylspermine (DiAcSpm) has been reported to be a useful tumor marker for various cancers. We aimed to examine the correlation between preoperative urinary DiAcSpm levels and specific clinicopathological characteristics such as the histological tumor invasiveness in patients with clinical stage IA non-small cell lung cancer (NSCLC). Methods We defined non-invasive tumors as NSCLC showing no vascular invasion, lymphatic permeation, pleural invasion, or lymph node metastasis. Preoperative urine samples were obtained from 516 consecutive patients with NSCLC resected at our institution between April 2008 and January 2013. Urinary DiAcSpm values were determined for all preoperative urine samples using the colloid gold aggregation procedure. Among these patients, 171 patients with clinical stage IA NSCLC met the criteria of our study cohort. Finally, we investigated the correlation between non-invasive tumor and urinary DiAcSpm levels. Results The median urine DiAcSpm for males was 147.2 nmol/g creatinine and 161.8 nmol/g creatinine in females. These median values were set as the cut-off values for each gender. Patients with higher urinary DiAcSpm levels frequently had significantly elevated serum CEA (p = 0.023) and greater lymph node metastasis (p = 0.048), lymphatic permeation (p = 0.046), and vascular invasion (p = 0.010). Compared with patients with non-invasive tumors, patients with invasive tumors had a tumor size >2.0 cm (p = 0.001), serum CEA >5.0 mg/dL (p < 0.001), high urinary DiAcSpm (p = 0.002), and a tumor disappearance rate (TDR) <0.75 (p < 0.001). Multivariate analysis revealed that a tumor size < 2.0 cm (RR = 2.901, 95% CI; 1.372-6.136, p = 0.005), high urinary DiAcSpm (RR = 3.374, 95% CI; 1.547-7.361, p = 0.002), and TDR < 0.75 (RR = 4.673, 95% CI; 2.178-10.027, p < 0.001) were independent predictors for invasive tumors. Conclusions We successfully showed that there was a significant correlation between urinary DiAcSpm levels and pathological tumor invasiveness in patients with clinical stage IA NSCLC. Further research would elucidate the clinical usefulness of DiAcSpm levels as a predictor of tumor invasiveness.

Abstract
The present study explored the use of methylated NDRG4 gene as a candidate biomarker for diagnosis of colorectal cancer (CRC). Methylated NDRG4 gene expression from colorectal carcinoma tissue, paracarcinoma tissues, stools, blood and urine were detected successfully in DNA samples from 84 patients, by nested methylation-specific polymerase chain reaction and denaturing high-performance liquid chromatography. The sensitivity and specificity of methylated NDRG4 gene expression for us as a biomarker in colorectal cancer was analyzed and compared with 16 age-matched healthy controls. The positive detection rate of methylated NDRG4 was 81% in carcinoma tissue, 8.3% in paracarcinoma tissues, 54.8% in blood, 72.6% in urine and 76.2% in stools. Considering the convenience of the acquisition of urine samples, an additional group of 76 patients with CRC were recruited for verification of detecting methylated NDRG4 in the urine. The positive detection rate of methylated NDRG4 was 72.4% (55/76) in this cohort. The detection of methylated NDRG4 in stools and urine could be used as a novel diagnostic technique for highly sensitive and specific detection of CRC. Due to the ease of collecting urine samples, this novel method could be a potential biomarker for early diagnosis of CRC.

Abstract
BACKGROUND N(1),N(12)-diacetylspermine (DiAcSpm) is a recently identified tumor marker. Its concentration increases in the urine of cancer patients at early clinical stages. To utilize this characteristic feature and thus contribute to the early detection of cancer, we developed an immunochromatographic determination system for DiAcSpm. METHODS We examined the factors that affect the performance and stability of our determination system, including antibody selection and the conditions for the formation of stably dispersed antibody-coated gold nanoparticles. We then tested the performance of the system by determining the DiAcSpm concentration in human urine samples. RESULTS We constructed an immunochromatographic strip using anti-DiAcSpm antibody-coated gold nanoparticles in the conjugate pad and an acetylspermine-protein conjugate (a DiAcSpm mimic) immobilized on the analyzing membrane. The use of the immunochromatographic strip and an immunochromato-reader allowed for the quantitative determination of DiAcSpm in the range of 20 to 700 nM. The analytical values obtained by this method were well correlated with those determined by a colloidal gold aggregation procedure using an automatic biochemical analyzer. The immunochromatographic strip was stable for at least 8 weeks at 50°C. CONCLUSIONS A competitive immunochromatographic device for DiAcSpm determination was developed in this study. This simple device will contribute to increasing the opportunities for early cancer detection and timely care.

Abstract
A rapid and sensitive ultraperformance liquid chromatography coupled with electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) method has been developed and validated for quantitatively determining diacetylpolyamines in the human fingernail. N(1),N(8)-diacetylspermidine (DiAct-Spd), N(1),N(12)- diacetylspermine (DiAct-Spm) and 1,6-diaminohexane (DAH) the [internal standard (IS)] were extracted from human fingernail samples by MeOH: 5 M HCl solution, followed by 4-(N,N-dimethylaminosulfonyl)-7-fluoro- 2,1,3-benzoxadiazole (DBD-F) derivatization, and then separated on an ACQUITY BEH C18 column with a gradient elution of acetonitrile and water containing 0.1% formic acid. The derivatives of the diacetylpolyamines were fully separated within a short run time (3.0 min). The triple quadrupole mass spectrometric detection was performed in the multiple reactions monitoring (MRM) mode by the UPLC-ESI- MS/MS system in the positive ionization mode. MRM using the fragmentation transitions of m/z 455.20→ 100.07, 737.25 → 100.07 and 567.10 → 479.07 in the positive ESI mode was performed to quantify DiAct-Spd, DiAct-Spm and IS, respectively. The calibration curve is between 0.04 ng mL(-1) for DiAct-Spd and DiAct-Spm. The detection limits (signal to noise ratio of five) were 5-10 pg mL(-1). A good linearity was achieved from the calibration curves (r(2) >0.9999), and the intra-day and inter-day assay precisions were less than 7.06%. Furthermore, the recoveries (%) of the diacetylpolyamines spiked in the human fingernails were 79.18-97.11. The present method proved that the high sensitivity is characterized by the specificity and feasibility of the sample analysis. Consequently, the proposed method was used to analyze human fingernail samples from 15 lung- cancer patients and 22 healthy volunteers. Diacetylpolyamines were detected from the fingernails of the lung- cancer patients for the first time. The concentration of DiAct-Spd in the lung-cancer patient group tended to be higher than those in the healthy volunteers.

Abstract
There has been evidence linking elevated polyamines (PAs) and acetylpolamines (AcPAs) level and cancer. So the simultaneous analysis of these compounds has become important task for cancer diagnosis and antitumor drug monitoring. A simple, fast and inexpensive CZE-LIF method has been developed for the determination of cadaverine (CAD), putrescine (PUT), spermine (SPM), spermidine (SPD), acetylspermine (ASPM), and acetylspermidine (ASPD) in human urine using 4-chloro-7-nitro-2,1,3-benzooxadiazole as a fluorescent reagent. Labeling reaction conditions were systematically investigated and were found to be 20 mM borate buffer at pH 7.4, labeling reaction time, and temperature were 10 min and 70°C, respectively. Under these optimized conditions the four PAs, two AcPAs and the internal standard were separated in 6 min. An Exactive-MS with an ESI source was used for identification of the bis-derivative of the ASPM. The method was validated in term of linearity, LODs, repeatability, intra- and interday assays, recovery, and selectivity. The LODs for CAD, PUT, SPM, SPD, ASPM, and ASPD were found to be 7.6, 10.0, 9.0, 8.8,7.8, and 3.3 nM, respectively. The method was successfully applied for the analysis of PAs and AcPAs in healthy human urine samples.

Abstract
A quantitative analysis of polyamines in lung cancer patient fingernails by the combination of 4-(N,N-dimethylaminosulfonyl)-7-fluoro-2,1,3-benzoxadiazole derivatives and liquid chromatography-electrospray ionization tandem mass spectrometry is described. The reaction of the reagent with eight kinds of polyamines, that is, N(1) -acetylputrescine (N(1) -actPUT), N(8) -acetylspermidine, N(1) -acetylspermine, 1,3-diaminopropane, putrescine (PUT), cadaverine, spermidine and spermine (SPM) effectively occurs at 60 °C for 30 min. The detection limits (signal-to-noise ratio 5) were 5-100 fmol. A good linearity was achieved from the calibration curves, which was obtained by plotting the peak area ratios of the analytes relative to the internal standard (IS), that is, 1,6-diaminohexane, vs the injected amounts of polyamines (r(2) > 0.996), and the intra-day and inter-day assay precisions were <9.84%. Furthermore, the recoveries (%) of the polyamines spiked in the human fingernails were 89.14-110.64. The present method was applied to human fingernail samples from 17 lung cancer patients and 39 healthy volunteers. The polyamine concentration was different based on the gender, that is, the N(1) -actPUT and PUT contents were 3.10 times and 2.56 times higher in healthy men than in women, respectively. Additionally, in the lung cancer patient group, as compared with the healthy volunteers, the concentrations of SPM had a statistically significant (p < 0.05) correlation. Therefore, because the proposed method provides a good mass accuracy and the trace detection of the polyamines in human fingernails, this analytical technique could be a noninvasive technique to assist in the diagnosis and assessment of disease activity in lung cancer patients.

Increase of N1, N12-diacetylspermine in tissues from colorectal cancer and its liver metastasis. J Cancer Res Clin Oncol 2013; 139:925-32.

Abstract
PURPOSE N (1),N (12)-Diacetylspermine (DiAcSpm) is a tumor marker featured by increase in the urine of patients with cancers, including early colorectal cancer, but where and how DiAcSpm is made remains unclear. We aimed to clarify whether colorectal cancer tissues produce increased amounts of DiAcSpm, and if they do, to examine whether tissue DiAcSpm level may serve as a criterion of tissue malignancy. METHODS Tissue samples were obtained from 140 patients (13 low-grade intraepithelial neoplasia, 98 high-grade intraepithelial neoplasia and 29 colorectal cancer) treated for colorectal cancer and intraepithelial neoplasia at Tokyo Metropolitan Komagome Hospital between November 2007 and April 2011. The DiAcSpm level in cancer and adjacent normal tissue extracts was compared, and its relationship with clinical stages of the diseases was analyzed. RESULTS DiAcSpm levels were higher in colorectal cancer tissue (p < 0.01, n = 12) and its liver metastasis (p < 0.05, n = 5) than in adjacent normal tissues. The tumor/normal ratio of tissue DiAcSpm content was examined for endoscopically obtained tumor and adjacent normal tissues from patients with intraepithelial neoplasia. The ratio was greater than 1.5 in 38 % (5/13) and 78 % (84/108) of low-grade intraepithelial neoplasia and high-grade intraepithelial neoplasia, respectively. CONCLUSIONS Tissue DiAcSpm levels increase in the tissue of colorectal cancer and also in precancerous lesion, such as high-grade intraepithelial neoplasia. The increase is considered a sign that a tissue is acquiring malignant characteristics. It is likely that the DiAcSpm produced by cancer cells is responsible for the frequent increase in urinary DiAcSpm in early cancer patients.

Abstract
An analytical method for the determination of three polyamines (putrescine, spermidine, and spermine) and five acetylpolyamines [N(1)-acetylspermidine (N(1)AcSpd), N(8)-acetylspermidine (N(8)AcSpd), N(1)-acetylspermine, N(1),N(8)-diacetylspermidine, and N(1),N(12)-diacetylspermine] involved in the polyamine catabolic pathway has been developed using a hybrid tandem mass spectrometer. Heptafluorobutyryl (HFB) derivatives of these compounds and respective internal standards labeled with stable isotopes were analyzed simultaneously by TOF MS, based on peak areas appearing at appropriate m/z values. The isomers, N(1)AcSpd and N(8)AcSpd were determined from their fragment ions, the acetylamidopropyl and acetylamidobutyl groups, respectively, using MS/MS with (13)C(2)-N(1)AcSpd and (13)C(2)-N(8)AcSpd which have the (13)C(2)-acetyl group as an internal standard. The TOF MS method was successfully applied to measure the activity of enzymes involved in polyamine catabolic pathways, namely N(1)-acetylpolyamine oxidase (APAO), spermine oxidase (SMO), and spermidine/spermine N(1)-acetyltransferase (SSAT). The following natural substrates and products labeled with stable isotopes considering the application to biological samples were identified; for APAO, [4,9,12-(15)N(3)]-N(1)-acetylspermine and [1,4,8-(15)N(3)]spermidine ((15)N(3)-Spd), respectively; for SMO, [1,4,8,12-(15)N(4)]spermine and (15)N(3)-Spd, respectively; and for SSAT, (15)N(3)-Spd and [1,4,8-(15)N(3)]-N(1)-acetylspermidine, respectively.

Abstract
The aim of this study was to evaluate the usefulness of urinary N(1),N(12)-diacetylspermine (DiAcSpm) measured by the colloidal gold aggregation method as a tumor marker for colorectal cancer (CRC). The preoperative urine of 113 CRC patients was collected, and the urinary DiAcSpm was measured by a reagent kit for DiAcSpm determination based on colloidal gold aggregation using automatic biochemical analyzers. The urinary DiAcSpm levels significantly correlated with distant metastasis and Tumor-Node-Metastasis (TNM) stage. The positive rates of urinary DiAcSpm were significantly higher than those of serum carcinoembryonic antigen (CEA) or cancer antigen 19-9 (CA19-9) in stages 0+I, II, III and IV. The positive rates of urinary DiAcSpm were also significantly higher than those of serum CEA or CA19-9 in the early and advanced CRC groups according to the Japan Classification of Colorectal Cancer. Therefore, urinary DiAcSpm, measured by a reagent kit for DiAcSpm determination based on colloidal gold aggregation, may be useful as a non-invasive tumor marker in patients with CRC.
