A Phase I Parallel Group Study in Healthy Subjects to Evaluate the Effect of Multiple Oral Doses of BI 1467335 and Phenelzine as Positive Control on Blood Pressure Response to Oral Tyramine (Double-blind, Randomised, Placebo-controlled Design for BI 1467335 Treatment Groups, Open Label for Phenelzine)

The main objective of the study is investigate the effect of escalating doses of oral tyramine on systolic blood pressure (SBP) at baseline and following an oral treatment with BI 1467335 up to 39 days at a low or high dose once daily compared to placebo and phenelzine (Nardil®) as positive control.

Expression of amine oxidase-related proteins in breast phyllodes tumor.

Article

作者: Kim, Hye Min ; Koo, Ja Seung

BACGROUNDBreast phyllodes tumors (BPTs) are difficult to differentiate from other tumor types. In-depth research is needed due to the insufficient description of the amine oxidase protein family, particularly in BPTs.OBJECTIVEThis study investigated the expression and clinical implications of amine oxidase-related proteins in BPTs.METHODSTissue microarrays were constructed (n=181), and amine oxidase-related proteins of monoamine oxidase (MAO) A, MAOB, lysyl oxidase (LOX), and primary-amine oxidase 3 (AOC3) were assessed using immunohistochemical staining. Staining patterns of these proteins were compared and analyzed with clinicopathologic parameters.RESULTSIn all, 149, 27, and 5 cases were classified as benign, borderline, and malignant, respectively. A higher grade of BPT was associated with increased MAOB (p<0.001), LOX (p=0.035), and AOC3 (p<0.001) expression. BPT cases with tumor recurrence and distant metastasis had higher proportions of MAOB positivity in stromal components (P=0.002 and 0.018, respectively). During follow-up, there was a significant association between MAOB positivity in the stromal component and shorter disease-free survival (DFS) (P=0.001) as well as overall survival (P=0.003). Moreover, MAOB positivity emerged as an independent factor for shorter DFS (hazard ratio: 4.253, 95% confidence interval: 1.034-17.49, P=0.045).CONCLUSIONSHigher MAOB, LOX, and AOC3 expression were observed in higher-grade BPTs, and MAOB expression was identified as a significant prognostic factor.

Expression of Amine Oxidase Proteins in Adrenal Cortical Neoplasm and Pheochromocytoma.

Article

作者: Koo, Ja Seung ; Kim, Eun Kyung

We delved into the expression of amine oxidase family proteins and their potential significance in adrenal gland neoplasm. Tissue microarrays were prepared for 132 cases of adrenal cortical neoplasm (ACN) consisting of 115 cases of adrenal cortical adenoma (ACA), 17 cases of adrenal cortical carcinoma (ACC), and 163 cases of pheochromocytoma (PCC). Immunohistochemical stainings for MAOA, MAOB, LOX, and AOC3 were performed to evaluate the H-scores and compare them with clinicopathological parameters. The H-scores of MAOA (T; p = 0.005) and MAOB (T; p = 0.006) in tumor cells (T) were high in ACN, whereas LOX (T, S; p < 0.001) in tumor and stromal cells (S) and AOC3 (T; p < 0.001) were higher in PCC. In stromal cells, MAOA (S; p < 0.001) and AOC3 (S; p = 0.010) were more expressed in ACA than in ACC. MAOB (S) in PCC showed higher H-scores when the grading of adrenal pheochromocytoma and paraganglioma (GAPP) score was 3 or higher (p = 0.027). In the univariate analysis, low MAOA expression in stromal cells of ACN was associated with shorter overall survival (p = 0.008). In conclusion, monoamine oxidase proteins revealed differences in expression between ACN and PCC and also between benign and malignant cells.

Study on plasma amino acids and piperonamide as potential diagnostic biomarkers of non-small cell lung cancer

Article

BackgroundThe value of plasma threonine, cysteine, and piperonamide as diagnostic biomarkers for non-small cell lung cancer (NSCLC) has been rarely explored. The lack of a validation set containing confounders is common to most previous metabolomics studies. The purpose of this study was to explore and validate the value of plasma amino acids and piperonamide as diagnostic biomarkers for NSCLC using liquid chromatography-tandem mass spectrometry (LC-MS/MS).MethodsA total of 250 participants were included in this study, including 167 patients with pathologically confirmed NSCLC and 83 healthy controls (HCs). These participants were divided into training set, validation set 1, and validation set 2 in chronological order and in a certain proportion. The plasma levels of 22 amino acids and 1 piperonamide in these pre-treatment NSCLC patients and HCs were measured by LC-MS/MS. Metabolic biomarkers were identified after multivariate analysis, univariate analysis, receiver operating characteristic (ROC) analysis. Furthermore, these biomarkers and transcriptomic data were subjected to joint pathway analysis.ResultsThe area under the ROC curve (AUC) values for threonine, piperonamide, arginine, alanine, cysteine, methionine, and histidine in the integrated data set were 0.911, 0.848, 0.909, 0.869, 0.786, 0.597 and 0.637, respectively. This panel composed of these 7 metabolites showed good diagnostic capability for NSCLC (the AUC of this diagnostic panel in each data set was greater than 0.9). The specificity of this diagnostic panel in validation set 2, which included confounders, was 0.970, similar to that of the other datasets. The presence of confounding factors had little effect on the diagnostic accuracy of this panel. The ROC analysis of this diagnostic panel between all stage I NSCLC patients and HCs showed AUC, sensitivity, and specificity of 1.000, 1.000, and 0.988, respectively. Moreover, PSAT1, SHMT2, AOC3, and MAOB were found to be involved in the metabolism of threonine and cysteine.ConclusionsPlasma amino acids and piperonamide have potential as diagnostic biomarkers in NSCLC. This metabolic biomarker panel appears useful for the diagnosis and screening of NSCLC. In addition, metabolomic and transcriptomic integration pathway analysis may help elucidate the mechanism of NSCLC occurrence and development and even reveal new treatment vulnerabilities.
