Abstract
Blood pressure is a crucial physiological parameter and its abnormalities can cause a variety of health problems. We have previously reported that mice with systemic deletion of nardilysin (NRDC), an M16 family metalloprotease, exhibit hypotension. In this study, we aimed to clarify the role of NRDC in vascular smooth muscle cell (VSMC) by generating VSMC-specific Nrdc knockout (VSMC-KO) mice. Our findings reveal that VSMC-KO mice also exhibit hypotension. Aortas isolated from VSMC-KO mice exhibited a weakened contractile response to phenylephrine, accompanied by reduced phosphorylation of myosin light chain 2 and decreased rhoA expression. VSMC isolated from VSMC-KO aortas showed a reduced increase in intracellular Ca2+ concentration induced by α-stimulants. These findings suggest that NRDC in VSMC regulates vascular contraction and blood pressure by modulating Ca2+ dynamics.

Abstract
Acute coronary syndrome (ACS) includes myocardial infarction (MI) and unstable angina (UA). MI is defined by elevated necrosis markers, preferably high-sensitivity cardiac troponins (hs-cTn). However, it takes hours for cTn to become elevated after coronary occlusion; therefore, difficulties are associated with diagnosing early post-onset MI or UA. The aim of this prospective cohort study was to examine the diagnostic ability of serum nardilysin (NRDC) for the early detection of ACS. This study consisted of two sequential cohorts, the Phase I cohort, 435 patients presenting to the emergency room (ER) with chest pain, and the Phase II cohort, 486 patients with chest pain who underwent coronary angiography. The final diagnosis was ACS in 155 out of 435 patients (35.6%) in the phase I and 418 out of 486 (86.0%) in the phase II cohort. Among 680 patients who presented within 24 h of onset, 466 patients (68.5%) were diagnosed with ACS. Serum NRDC levels were significantly higher in patients with ACS than in those without ACS. The sensitivity of NRDC in patients who presented within 6 h after the onset was higher than that of hsTnI, and the AUC of NRDC within 1 h of the onset was higher than that of hsTnI (0.718 versus 0.633). Among hsTnI-negative patients (300 of 680 patients: 44.1%), 136 of whom (45.3%) were diagnosed with ACS, the sensitivity and the NPV of NRDC were 73.5 and 65.7%, respectively. When measured in combination with hsTnI, NRDC plays auxiliary roles in the early diagnosis of ACS.

Abstract
The identification of new genes/proteins involved in breast cancer (BC) occurrence is widely used to discover novel biomarkers and understand the molecular mechanisms of BC initiation and progression. The jumping translocation breakpoint (JTB) gene may act both as a tumor suppressor or oncogene in various types of tumors, including BC. Thus, the JTB protein could have the potential to be used as a biomarker in BC, but its neoplastic mechanisms still remain unknown or controversial. We previously analyzed the interacting partners of JTBhigh protein extracted from transfected MCF7 BC cell line using SDS-PAGE complemented with in-solution digestion, respectively. The previous results suggested the JTB contributed to the development of a more aggressive phenotype and behavior for the MCF7 BC cell line through synergistic upregulation of epithelial-mesenchymal transition (EMT), mitotic spindle, and fatty acid metabolism-related pathways. In this work, we aim to complement the previously reported JTB proteomics-based experiments by investigating differentially expressed proteins (DEPs) and tumorigenic pathways associated with JTB overexpression using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE). Statistically different gel spots were picked for protein digestion, followed by nanoliquid chromatography-tandem mass spectrometry (nLC-MS/MS) analysis. We identified six DEPs related to the JTBhigh condition vs. control that emphasize a pro-tumorigenic (PT) role. Twenty-one proteins, which are known to be usually overexpressed in cancer cells, emphasize an anti-tumorigenic (AT) role when low expression occurs. According to our previous results, proteins that have a PT role are mainly involved in the activation of the EMT process. Interestingly, JTB overexpression has been correlated here with a plethora of significant upregulated and downregulated proteins that sustain JTB tumor suppressive functions. Our present and previous results sustain the necessity of the complementary use of different proteomics-based methods (SDS-PAGE, 2D-PAGE, and in-solution digestion) followed by tandem mass spectrometry to avoid their limitations, with each method leading to the delineation of specific clusters of DEPs that may be merged for a better understanding of molecular pathways and neoplastic mechanisms related to the JTB's role in BC initiation and progression.

Abstract
It has been reported that nardilysin (NRDC), a metalloendopeptidase which regulates various growth factors and cytokines, is associated with malignancies in a conflicting manner, in which it promoted gastric, hepatocellular, and colorectal cancers and suppressed pancreatic ductal adenocarcinoma. However, it has not been investigated how NRDC is associated with cutaneous malignancies for now. Immunohistochemical staining has revealed that NRDC expression is observed in all extramammary Paget's disease (EMPD) cases. Notably, other cutaneous malignancies including basal cell carcinoma, squamous cell carcinoma, and eccrine porocarcinoma, did not show increased NRDC expression in immunohistochemistry. EMPD typically presents several types of lesions including nodules, and positive staining of NRDC on EMPD was observed regardless of the type of lesions. Examination using samples taken from nodular lesions showed that some cases showed heterogenous NRDC expression within each lesion. We also found that NRDC staining was weaker in the marginal parts of EMPD lesion than in the central parts in several cases, and tumor cells tend to be distributed beyond the macroscopic skin lesions in these cases. It was speculated that decreased NRDC expression in the marginal zones of the skin lesions may be associated with the ability of tumor cells to produce the cutaneous manifestation of EMPD. This study suggests that NRDC may be associated with EMPD like other malignancies reported previously.

Abstract
The tumor suppressor p53 is a transcription factor that regulates the expression of dozens of target genes and diverse physiological processes. To precisely regulate the p53 network, p53 undergoes various post-translational modifications and alters the selectivity of target genes. Acetylation plays an essential role in cell fate determination through the activation of p53. Although the acetylation of p53 has been examined, the underlying regulatory mechanisms remain unclear and, thus, have attracted the interest of researchers. We herein discuss the role of acetylation in the p53 pathway, with a focus on p53 acetyltransferases and deacetylases. We also review recent findings on the regulators of these enzymes to understand the mode of p53 acetylation from a broader perspective.

Abstract
Colorectal cancer (CRC) belongs to the most common tumor types, and half of all CRC harbor missense mutations in the TP53 tumor suppressor gene. In addition to genetically caused loss of function of p53, epigenetic alterations (DNA methylation, histone modifications, micro-RNAs) contribute to CRC development. In this review, we focused on epigenetic alterations related to the entire p53 signaling pathway upstream and downstream of p53. Methylation of genes which activate p53 function has been reported, and methylation of APC and MGMT was associated with increased mutation rates of TP53. The micro-RNA 34a activates TP53 and was methylated in CRC. Proteins that regulate TP53 DNA methylation, mutations, and acetylation of TP53-related histones were methylated in CRC. P53 regulates the activity of numerous downstream proteins. Even if TP53 is not mutated, the function of wildtype p53 may be compromised if corresponding downstream genes are epigenetically inactivated. Thus, the role of p53 for CRC development, therapy response, and survival prognosis of patients may be much more eminent than previously estimated. Therefore, we propose that novel diagnostic devices measuring the entirety of genetic and epigenetic changes in the "p53 signalome" have the potential to improve the predictive and prognostic power in CRC diagnostics and management.

Abstract
Nardilysin (NRDC) has been shown to be involved in post-translational histone modifications, in addition to enhancement in ectodomain shedding of membrane-anchored protein, which play significant roles in various pathophysiology, including glucose homeostasis, inflammatory diseases and cancer. The present study sought to determine roles of NRDC in the liver on lipid and lipoprotein metabolism. We established liver-specific NRDC deficient mice by use of NRD1 floxed mice and albumin promoter-Cre recombinase (Cre) transgenic mice, and found that their serum low-density lipoprotein (LDL) cholesterol levels were significantly lower than those in control littermate mice. In the liver, LDL receptor (LDLR) mRNA expression was significantly upregulated, while inducible degrader of LDLR (IDOL) and microsomal triglyceride transfer protein (MTP) mRNA expression was significantly downregulated, in liver-specific NRDC deficient mice. Hepatic cell-surface LDLR expression levels were significantly elevated and serum pro-protein convertase subtilisin-kexin type 9 (PCSK9) levels were significantly reduced in mice with hepatic NRDC deficiency. In cultured hepatocytes, NRDC deficiency significantly reduced secreted PCSK9 and increased cell-surface LDLR expression. On the other hand, NRDC overexpression in cultured hepatocytes significantly increased secreted PCSK9 and lowered cell-surface LDLR expression. Thus, NRDC in murine hepatocytes appears to play key roles in cholesterol homeostasis, although the precise molecular mechanisms remain to be determined.

Abstract
Cardiac sympathetic innervation is critically involved in the regulation of circulatory dynamics. However, the molecular mechanism for the innervation patterning has remained elusive. Here, we demonstrate that nardilysin (NRDC, Nrdc), an enhancer of ectodomain shedding, regulates cardiac sympathetic innervation. Nardilysin-deficient (Nrdc-/- ) mice show hypoplastic hearts, hypotension, bradycardia, and abnormal sympathetic innervation patterning. While the innervation of left ventricle (LV) of wild-type mice is denser in the subepicardium than in the subendocardium, Nrdc-/- LV lacks such a polarity and is uniformly and more abundantly innervated. At the molecular level, the full-length form of p75 neurotrophin receptor (p75NTR , Ngfr) is increased in Nrdc-/- LV due to the reduced ectodomain shedding of p75NTR . Importantly, the reduction of p75NTR rescued the abnormal innervation phenotype of Nrdc-/- mice. Moreover, sympathetic neuron-specific, but not cardiomyocyte-specific deletion of Nrdc recapitulated the abnormal innervation patterning of Nrdc-/- mice. In conclusion, neuronal nardilysin critically regulates cardiac sympathetic innervation and circulatory dynamics via modulation of p75NTR .

Abstract
LncRNAs have been demonstrated to play pivotal roles in virous biological processes, especially the gene expression regulation, including transcriptional regulation, posttranscriptional control and epigenetic processes. However, most of the current studies of lncRNAs are still limited in mammalian species, the investigations of functional roles of lncRNAs in teleost species are still lacking. In current study, we identified a novel lncRNA (SETD3-OT) in turbot, with 2,504 bp full-length obtained by 5' and 3' RACE, located in turbot chromosome 17, ranged from 20,933,835 to 20,936,302 bp. In addition, 8 neighboring genes of SETD3-OT were identified within 100 kbp in genome location. From the annotation of the neighboring adjacent genes, SETD3-OT might involve in regulation of cell apoptosis and cycle, the immune cell development, and the immune response against infection, and its expression pattern is similar to majority of the neighboring genes following Aeromonas salmonicida challenge. Intriguingly, SETD3-OT showed significant high expression levels in mucosal surfaces (intestine, gill and skin), and was dramatically down-regulated in these mucosal tissues following Vibrio anguillarum challenge, especially in gill and skin. In addition, SETD3-OT was distributed in nucleus, it might regulate the neighboring genes in cis or in trans. Taken together, our results provide insights for lncRNA in fish innate immunity, further studies should be conduct to explore the detailed molecular mechanism of the gene regulation between SETD3-OT and its neighboring genes.

Li L, Zheng Y, Zhang W, Hou L, Gao Y. Scutellarin circumvents chemoresistance, promotes apoptosis, and represses tumor growth by HDAC/miR-34a-mediated down-modulation of Akt/mTOR and NF-κB-orchestrated signaling pathways in multiple myeloma. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2020; 13:212-219. [PMID: 32211101 PMCID: PMC7061792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Accepted: 01/23/2020] [Indexed: 06/10/2023]
Abstract
Multiple myeloma (MM) is a neoplastic dyscrasia of monoclonal immunoglobulin-secreting plasma cells culminating in multi-organ dysfunction. In this study, we sought to investigate whether scutellarin (STN), a flavonoid, could reduce MM progression, mitigate chemoresistance of MM cells to bortezomib (BTB), and cause MM cell apoptosis in a xenograft mouse model of MM. Epigenetic signalling plays a main role in the modulation of various pathways involved in multiple myeloma progression. At the outset, mechanistic analyses of the MM pathways indicated that key epigenetic molecules including HDAC1/3 and miR-34a were up-modulated and down-modulated respectively, in the MM mice. Besides, the downstream signalling analysis of miR-34a depicted that the c-Met/AKT/mTOR pathway was activated in the MM mice. We also investigated the expression of NF-κB, one of the major chemoresistance inducers in cancer treatment, in the MM mice. As anticipated, the tumor-bearing mice expressed more NF-κB along with elevated anti-apoptotic Bcl-xL protein, as well as reduced pro-apoptotic Bim protein. On the other hand, STN+BTB co-treatment effectively combated the MM tumor progression, and STN circumvented the MM tumor resistance to BTB and provoked apoptotic cell death in MM. Based on our study data, we deduce that STN, in combination with BTB, appears to be a reliable tumoricidal strategy.

Serum Nardilysin, a Surrogate Marker for Epithelial-Mesenchymal Transition, Predicts Prognosis of Intrahepatic Cholangiocarcinoma after Surgical Resection. Clin Cancer Res 2019; 25:619-628. [PMID: 30352908 DOI: 10.1158/1078-0432.ccr-18-0124] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 07/21/2018] [Accepted: 10/19/2018] [Indexed: 11/16/2022]
Abstract
PURPOSE Few studies have investigated prognostic biomarkers in patients with intrahepatic cholangiocarcinoma (ICC). Nardilysin (NRDC), a metalloendopeptidase of the M16 family, has been suggested to play important roles in inflammation and several cancer types. We herein examined the clinical significance and biological function of NRDC in ICC.Experimental Design: We measured serum NRDC levels in 98 patients with ICC who underwent surgical resection in two independent cohorts to assess its prognostic impact. We also analyzed NRDC mRNA levels in cancerous tissue specimens from 43 patients with ICC. We investigated the roles of NRDC in cell proliferation, migration, gemcitabine sensitivity, and gene expression in ICC cell lines using gene silencing. RESULTS High serum NRDC levels were associated with shorter overall survival and disease-free survival in the primary (n = 79) and validation (n = 19) cohorts. A correlation was observed between serum protein levels and cancerous tissue mRNA levels of NRDC (Spearman ρ = 0.413; P = 0.006). The gene knockdown of NRDC in ICC cell lines attenuated cell proliferation, migration, and tumor growth in xenografts, and increased sensitivity to gemcitabine. The gene knockdown of NRDC was also accompanied by significant changes in the expression of several epithelial-mesenchymal transition (EMT)-related genes. Strong correlations were observed between the mRNA levels of NRDC and EMT-inducing transcription factors, ZEB1 and SNAI1, in surgical specimens from patients with ICC. CONCLUSIONS Serum NRDC, a possible surrogate marker reflecting the EMT state in primary tumors, predicts the outcome of ICC after surgical resection.
