Adenosquamous carcinoma of the pancreas (ASCP) is an uncommon variant of exocrine pancreatic malignancies, characterized by a histological admixture of adenomatous and squamous cell elements. This cancer is characterized by a poorly differentiated histology and a poorer clinical outcome compared to pancreatic ductal adenocarcinoma (PDAC). Unlike PDAC, that is characterized by a low microvascular density (MVD) and collapsed vasculature, no data are available about angiogenesis in ASPC. Immunohistochemical evaluation of MVD and trypatse-positive mast cells (MCs) were performed on a single case of ASCP compared to PDAC...

OBJECTIVE: By investigating the migration and invasion ability in pancreatic cancer, this study probed into the lncRNA MALAT1 molecular mechanism on Hippo-YAP signaling. METHODS: The expression of lncRNA MALAT1 in PC tissues and cells was detected by qRT-PCR and western blot. The effect of si-MALAT1 on proliferation was determined by CCK-8 assay. Cell apoptosis, migration and invasion were respectively detected by flow cytometry assay, wound healing assay and transwell assay...

OBJECTIVE: To review the literature systematically and perform meta-analyses to address these questions: 1) Is there evidence that self-measured blood pressure (BP) without other augmentation is superior to office-based measurement of BP for achieving better BP control or for preventing adverse clinical outcomes that are related to elevated BP? 2) What is the optimal target for BP lowering during antihypertensive therapy in adults? 3) In adults with hypertension, how do various antihypertensive drug classes differ in their benefits and harms compared with each other as first-line therapy? METHODS: Electronic literature searches were performed by Doctor Evidence, a global medical evidence software and services company, across PubMed and EMBASE from 1966 to 2015 using key words and relevant subject headings for randomized controlled trials that met eligibility criteria defined for each question...

MicroRNAs have been reported to play an important role in tumor development and progression by targeting oncogenes and tumor suppressors. miR-23a has been described as significantly upregulated in multiple cancers and involved in tumorigenesis. The aim of this study was to evaluate the potential roles of miR-23a in pancreatic ductal adenocarcinoma (PDAC). We found that miR-23a level was significantly increased in tissues of PDAC compared with that in the control by real-time PCR. FOXP2 expression was downregulated and inversely correlated with miR-23a...

BACKGROUND: The medical applications of nonequilibrium atmospheric pressure plasma in cancer therapy have attracted attention. We previously reported on the antitumor effect of plasma-activated medium. However, this approach requires plasma-activated liquids that are administrable to the human body. In this study, we produced plasma-activated lactated Ringer's solution (PAL) and evaluated its antitumor effect and mechanism. Furthermore, we evaluated the effect of the intraperitoneal administration of PAL using a peritoneal dissemination mouse tumor model...

miR-23a plays vital roles in various cancer metastases. Here, we found that miR-23a expression was significantly up-regulated in pancreatic cancer tissues compared with adjacent normal tissues. miR-23a up-regulation was significantly associated with differentiated degree, lymphoid nodal status, tumor invasion and poor survival rate in pancreatic cancer patients. We also found that miR-23a expression was significantly up-regulated in lymph node metastatic tissues and in pancreatic cancer cells that underwent epithelial-mesenchymal transition (EMT)...

Pancreatic ductal adenocarcinoma (PDAC) displays a highly aggressive malignancy and is considered to be an incurable and rapidly lethal disease. MicroRNAs (miRNAs) are small non-coding RNAs of approximately nucleotides that regulate several aspects of tumors pathogenesis, including migration, invasion, metastasis and epithelial-mesenchymal transition. We have found that miR-107 was significantly high expression in PDAC tissues and cells. High miR-107 expression is associated with poor clinicopathological parameters and prognosis in PDAC patients...

Resistance to chemoradiotherapy is one reason for the increased recurrence rate of pancreatic cancer after these therapies. These cells change the expression levels of several proteins, such as epithelial-mesenchymal transition (EMT), while acquiring the chemo- or radio-resistance. In this study, we focused on CD44, a pancreatic cancer stem cell marker. CD44 has isoforms with different functions: standard isoform (CD44s) and several variant isoforms (CD44v). However, little is known about the roles of these isoforms after ionizing irradiation...

A family of phosphamide-containing diphenylpyrimidine analogues (PA-DPPYs) were synthesized as potent focal adhesion kinase (FAK) inhibitors. The PA-DPPY derivatives could significantly inhibit the FAK enzymatic activity at concentrations lower than 10.69 nM. Among them, compounds 7a and 7e were two of the most active FAK inhibitors, possessing IC50 values of 4.25 nM and 4.65 nM, respectively. In particular, compound 7e also displayed strong activity against AsPC cell line, with an IC50 of 1.66 μM, but show low activity against the normal HPDE6-C7 cells (IC50 > 20 μM), indicating its low cell cytotoxicity...

The pancreatic stellate cell (PSC) is the principal cell type of the desmoplastic stroma of pancreatic ductal adenocarcinoma (PDAC). PSCs interact with cancer cells and influence the progression of the disease through a complex network of signaling molecules including hepatocyte growth factor (HGF). Functional heterogeneity of PSCs within a tumor might conceivably influence tumor progression. We investigated PSC populations isolated from different human PDACs and examined the effects of PSC-conditioned medium on BxPC-3 and AsPC-1 pancreatic cancer cells...

A wealth of evidence suggests that proteins from prion protein (PrP) family contribute to tumorigenesis in many types of cancers, including pancreatic ductal adenocarcinoma (PDAC), breast cancer, glioblastoma, colorectal cancer, gastric cancer, melanoma, etc. It is well documented that PrP is a biomarker for PDAC, breast cancer, and gastric cancer. However, the underlying mechanisms remain unclear. The major reasons for cancer cell-caused patient death are metastasis and multiple drug resistance, both of which connect to physiological functions of PrP expressing in cancer cells...

MicroRNAs (miRNAs) play important roles in the regulation of various tumor biological processes including proliferation and apoptosis. miR-217 has been implicated in many types of cancer, whereas its expression and potential biological function in human pancreatic adenocarcinoma (HPAC) remain unclear. We aimed to investigate the clinical significance of miR-217 in patients with pancreatic carcinoma and its role and underlying molecular mechanism in HPAC. We collected 15 pairs of pancreatic cancer and normal pancreas tissues to evaluate the expression of miR-217 and tumor protein D52-like 2 (Tpd52l2)...

Summary: Whole genome sequencing (WGS) is being adopted in public health for improved surveillance and outbreak analysis. In public health, subtyping has been used to infer phenotypes and distinguish bacterial strain groups. In silico tools that predict subtypes from sequences data are needed to transition historical data to WGS-based protocols. Phylotyper is a novel solution for in silico subtype prediction from gene sequences. Designed for incorporation into WGS pipelines, it is a general prediction tool that can be applied to different subtype schemes...

Erlotinib has shown activity in the management of pancreatic cancer. However, the benefit of EGFR blockade is limited due to EGFR independent PI3K/Akt signaling pathway. Studies have reported that Ginsenoside Rg3 strongly inhibited PI3K-Akt signaling pathway of many carcinomas. We aimed to investigate the activity of Ginsenoside Rg3 to sensitize erlotinib in treating pancreatic cancer in vitro and in vivo. Human pancreatic cancer cell lines BxPC-3 and AsPC-1 were used. Cell proliferation and colony formation assay, Annexin V/PI apoptosis analysis, Western blot analysis, immunohistochemistry and in vivo study were carried out...

BACKGROUND: Anoctamin (ANO)/transmembrane member 16 (TMEM16) proteins mediate diverse physiological and pathophysiological functions including cancer cell proliferation. The present study aimed to identify the role of ANOs in pancreatic cancer. METHODS: In an initial screen of ANOs, ANO9/TMEM16J was overexpressed in pancreatic cancer cells, and its role in the pathogenesis of pancreatic cancer was evaluated using an integrated in vitro and in vivo approach. To determine clinical relevance of the experimental findings, the prognostic value of ANO9 was evaluated in patients with pancreatic cancer...
