Several studies have recently reported that KRAB zinc finger protein 382 (ZNF382) is downregulated in multiple carcinoma types due to promoter methylation. The exact role of ZNF382 in gastric carcinogenesis, however, remains elusive. In this study, we investigated the alterations and functions of ZNF382 in the pathogenesis of gastric cancer (GC). Semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR), quantitative (real-time) PCR (qPCR) and immunohistochemistry were carried out to detect the expression patterns of ZNF382 in GC cell lines and gastric tissue samples...

Background: Two primary histologic subtypes, superficial spreading melanoma (SSM) and nodular melanoma (NM), comprise the majority of all cutaneous melanomas. NM is associated with worse outcomes, which have been attributed to increased thickness at presentation, and it is widely expected that NM and SSM would exhibit similar behavior once metastasized. Herein, we tested the hypothesis that primary histologic subtype is an independent predictor of survival and may impact response to treatment in the metastatic setting...

Pancreatic cancer is the fourth leading cause of cancer-associated mortality in developed countries. Pancreatic ductal adenocarcinoma (PDAC) accounts for ~90% of all pancreatic cancer cases. The Notch signaling pathway serves a crucial role in embryonic development, as well as during the tumorigenesis of different types of cancer. However, Notch signaling serves either oncogenic or tumor suppressor roles depending on the tissue type. There are four Notch receptors (Notch1-4) and five ligands [Jagged1, Jagged2, δ-like ligand protein (DLL)1, DLL3 and DLL4]; therefore, it has been suggested that the different Notch receptors serve distinct roles in the same type of tissue...

Drug-related sinusoidal dilatation (SD) is a common form of hepatotoxicity associated with oxaliplatin-based chemotherapy used prior to resection of colorectal liver metastases (CRLM). Recently, hepatic SD has also been associated with anti-delta like 4 (DLL4) cancer therapies targeting the NOTCH pathway. To investigate the hypothesis that NOTCH signaling plays an important role in drug-induced SD, gene expression changes were examined in livers from anti-DLL4 and oxaliplatin-induced SD in non-human primate (NHP) and patients, respectively...

PURPOSE: In cancer patients, tumor gene mutations contribute to drug resistance and treatment failure. In patients with metastatic breast cancer (MBC), these mutations increase after multiline treatment, thereby decreasing treatment efficiency. The aim of this study was to evaluate gene mutation patterns in MBC patients to predict drug resistance and disease progression. METHOD: A total of 68 MBC patients who had received multiline treatment were recruited. Circulating tumor DNA (ctDNA) mutations were evaluated and compared among hormone receptor (HR)/human epidermal growth factor receptor 2 (HER2) subgroups...

Notch4, a family member of the Notch signaling pathway, has important roles in cellular developmental pathways, including proliferation, differentiation and apoptosis. The present study aimed to investigate the association between Notch4 expression and clinical outcomes with immunohistochemistry. Notch4 was expressed in 55.6% of triple-negative breast cancer (TNBC), 45.8% of Her-2-overexpressing and 25.5% of luminal breast cancer cases, with significantly higher expression occurring in TNBC (P<0.05). Furthermore, Notch4 expression was inversely associated with estrogen receptor (ER) and/or progesterone receptor positivity, and positively associated with larger tumor size, more lymph node involvement, and more advanced tumor node metastasis stage (P<0...

The NOTCH signalling pathway is an essential pathway, involved in many cellular processes, including cell fate decision, cell proliferation, and cell death and important in the development of most organs. Mutations in genes encoding components of the NOTCH signalling pathway lead to a spectrum of congenital disorders. Over the past decades, mutations in human NOTCH signalling genes have been identified in several diseases with cardiovascular involvement. NOTCH1 mutations have been described in bicuspid aortic valve disease, left-sided congenital heart disease, and Adams-Oliver syndrome...

Exosomes are nanovesicles released from most cell types including immune cells. Prior studies suggest exosomes play a role in HIV pathogenesis, but little is known about exosome cargo in relation to immune responses and oxidative stress. Here, we characterize plasma exosomes in HIV patients and their relationship to immunological and oxidative stress markers. Plasma exosome fractions were isolated from HIV-positive subjects on ART with suppressed viral load and HIV-negative controls. Exosomes were characterized by electron microscopy, nanoparticle tracking, immunoblotting, and LC-MS/MS proteomics...

The detection of recurrent mutations affecting the hormone binding domain (HBD) of estrogen receptor alpha (ERα/ESR1) in endocrine therapy-resistant and metastatic breast cancers has prompted interest in functional characterization of these genetic alterations. Here, we explored the role of HBD-ESR1 mutations in influencing the behavior of breast cancer stem cells (BCSCs), using various BC cell lines stably expressing wild-type or mutant (Y537 N, Y537S, D538G) ERα. Compared to WT-ERα clones, mutant cells showed increased CD44+ /CD24- ratio, mRNA levels of stemness genes, Mammosphere Forming Efficiency (MFE), Self-Renewal and migratory capabilities...

Notch signal has complex roles in human malignancies, which might be attributed to the diversity of Notch receptors. Here, we set out to identify the association of NOTCH4 with colorectal cancer (CRC). In the hospital-based study cohort, we investigated NOTCH4 mRNA levels in primary CRC, as well as its association with clinicopathologic characteristics. Besides, NOTCH4 cDNA and siRNA was transfected into colorectal cancer cell line to elucidate its impact on tumor cell proliferation and migration. Results revealed a statistically significant lower expression of NOTCH4 mRNA in tumor specimens compared with that in control...

To unveil novel global changes associated with corpus luteum (CL) maturation, we analyzed transcriptome data for the bovine CL on days 4 and 11, representing the developing vs. mature gland. Our analyses revealed 681 differentially expressed genes (363 and 318 on day 4 and 11, respectively), with ≥2 fold change and FDR of <5%. Different gene ontology (GO) categories were represented prominently in transcriptome data at these stages (e.g. days 4: cell cycle, chromosome, DNA metabolic process and replication and on day 11: immune response; lipid metabolic process and complement activation)...

BACKGROUND: The incidence of dilated cardiomyopathy (DCM) has increased in recent years, and many studies have sought to further improve the general understanding of this condition. Previous studies have demonstrated that some single nucleotide polymorphisms (SNPs) associated with systemic lupus erythematosus also affect susceptibility to DCM, suggesting that immune-related diseases may share similar genetic susceptibility. Recent large-scale and genome-wide association studies have identified NCR3, NOTCH4, CYP1A2, ITGA1, OPRM1, ST8SIA2, and LINC00704 as genetic risk factors associated with cardiac manifestations of neonatal lupus...

Notch signaling is an evolutionary conserved signaling pathway that plays an indispensable role during development, and in the maintenance of homeostatic processes, in a wide variety of tissues (Kopan, 2012; Hori et al., 2013). The multifaceted roles of Notch signaling are stringently regulated at different levels. One of the most important aspects of regulation is the binding of different Notch ligands to each Notch receptor (NOTCH1-NOTCH4). Canonical ligands Delta or Serrate (in Drosophila ), and Delta-like (DLL1 and DLL4) or Jagged (JAG1 and JAG2) (in mammals), are transmembrane glycoproteins...

Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) infection remains a global threat to human health, but knowledge of the molecular mechanisms underlying the pathogenesis of TB is still limited. Although Notch4, a member of the Notch receptor family, is involved in the initiation of mammary tumors, its function in Mtb infection remains unclear. In this study, we found that Notch4-deficient mice were more resistant to Mtb infection with a much lower bacterial burden and less pathological changes in the lungs...

INTRODUCTION: Oral verrucous carcinoma is a special form of well-differentiated squamous cell carcinoma which possesses specific clinical, morphologic and cytokinetic features that differ from other types of oral cancers and hence diagnosis requires immense experience in histopathology. Hence it is certainly important to distinguish such a lesion from other oral tumors as treatment strategies vary widely between them. OBJECTIVE: In search of a critical diagnostic marker in distinguishing oral verrucous carcinoma from oral squamous cell carcinoma, Notch4 receptor, one of the key regulatory molecules of the Notch signaling family has been aberrantly activated in the progression of several types of tumors...

Purpose: Recently, several comprehensive genomic analyses demonstrated NOTCH1 and NOTCH3 mutations in head and neck squamous cell carcinoma (HNSCC) in approximately 20% of cases. Similar to other types of cancers, these studies also indicate that the NOTCH pathway is closely related to HNSCC progression. However, the role of NOTCH4 in HNSCC is less well understood. Experimental Design: We analyzed NOTCH4 pathway and downstream gene expression in the TCGA data set. To explore the functional role of NOTCH4 , we performed in vitro proliferation, cisplatin viability, apoptosis, and cell-cycle assays...
