Upregulation of ASPM, BUB1B and SPDL1 in tumor tissues predicts poor survival in patients with pancreatic ductal adenocarcinoma.

Upregulation of ASPM, BUB1B and SPDL1 in tumor tissues predicts poor survival in patients with pancreatic ductal adenocarcinoma. Oncol Lett. 2020 Apr;19(4):3307-3315 Authors: Tian X, Wang N Abstract Pancreatic ductal adenocarcinoma (PDAC) remains a major cause of cancer-associated mortality, with poor patient outcome. The present study aimed to identify key candidate genes and investigate the potential molecular mechanisms associated with the progression of PDAC. The GSE46234 dataset was downloaded from the Gene Expression Omnibus database, in order to identify the upregulated differentially expressed genes (DEGs) in PDAC. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to determine the biological functions and pathways of the upregulated DEGs, and a protein-protein interaction (PPI) network was subsequently constructed to screen the hub genes. Subsequently, survival analyses of the hub genes were undertaken in patients with PDAC, using The Cancer Genome Atlas dataset. Reverse transcription-quantitative (RT-q)PCR analysis was performed to assess the mRNA expression levels of the hub genes associated with the prognosis of patients with PDAC. In the present study, 65 upregulated DEGs were identified. GO analysis suggested that the DEGs were enriched in response to hypoxia, calcium ion and negative regulation of catecholamine. KEGG analysis demonstrated that the DEGs were enriched in gastric acid secretion, the E...

Pan‑cancer analysis of transmembrane protease serine 2 and cathepsin L that mediate cellular SARS‑CoV‑2 infection leading to COVID-19. Int J Oncol. 2020 May 26;: Authors: Katopodis P, Anikin V, Randeva HS, Spandidos DA, Chatha K, Kyrou I, Karteris E Abstract Severe acute respiratory syndrome (SARS) coronavirus‑2 (SARS‑CoV2) is the cause of a new disease (COVID‑19) which has evolved into a pandemic during the first half of 2020. Older age, male sex and certain underlying diseases, including cancer, appear to significantly increase the risk for severe COVID‑19. SARS‑CoV‑2 infection of ...

ConclusionPSD can be performed with a low but definable risk of long-term morbidity. Risk of gastric and jejunal carcinoma rarely occurs and was diagnosed decades after PSD. This demonstrates the need for lifelong endoscopic surveillance and educates us on the risk of carcinoma in the remaining gastrointestinal tract.

Contributors : Ajay Goel ; Raju Kandimalla ; Wei Li ; Jianfeng XuSeries Type : Methylation profiling by high throughput sequencingOrganism : Homo sapiensOwing to high cancer-specificity, DNA methylation alterations have emerged as front-runners in cell-free DNA (cf-DNA) biomarker development. However, much effort to date has focused on single cancers and have not explored the possibility of developing a pan-cancer diagnostic assay. Here, we undertook a genome-wide DNA methylation analysis for multiple gastrointestinal (GI) cancers, to develop a panGI diagnostic assay. By analyzing the DNA methylation data from 1940 tumor a...

Authors: Zhu LJ, Pan Y, Chen XY, Hou PF Abstract Budding uninhibited by benzimidazoles 1 (BUB1) is a mitotic checkpoint serine/threonine kinase that has been reported as an oncogene or tumor suppressor gene in various types of cancer, including breast cancer, pancreatic ductal adenocarcinoma, prostate and gastric cancers. However, its role in liver cancer remains unclear. The present study aimed to explore the biological function of BUB1 in liver cancer. The present study demonstrated that BUB1 mRNA expression levels and the intensity of immunohistochemical staining were significantly increased in liver cancer tiss...

The clinical application of photodynamic therapy (PDT) for gastrointestinal (GI) neoplastic lesions has been developed with appreciation for the great efforts and kind support of Dr. Tom Dougherty and his followers ’ contributions.There are several published studies on clinical PDT in the field of GI oncology including esophageal cancer, Barret’s esophagus, gastric cancer, biliary cancer and pancreatic cancer. In this review, we overview the history, present status and future perspective of PDT for GI canc er in clinical. AbstractThe clinical application of photodynamic therapy (PDT) for gastrointestinal (GI) n...

This study assesses survival improvement across a decade (2004 –2013) among patients with metastatic gastrointestinal cancers in a real-world setting.MethodsSurveillance, Epidemiology and End Results (SEER) database was accessed and patients with metastatic gastrointestinal carcinomas who have received any form of systemic therapy were included. Patients were grouped into three cohorts based on the year of diagnosis (cohort-1: 2004 –2006; cohort-2: 2008–2010; cohort-3: 2012–2013). Overall survival was compared among the three cohorts for each disease site using Kaplan-Meier survival estimates.Result...

Arcangeli Ivana Novak Pancreatic duct cells are equipped with acid/base transporters important for exocrine secretion. Pancreatic ductal adenocarcinoma (PDAC) cells may utilize such transporters to acidify extracellular tumor microenvironment, creating a niche favoring cell proliferation, fibrosis and resistance to chemotherapy—all contributing to the notoriously bad prognosis of this disease. Here, we report that gastric and non-gastric H+, K+-ATPases (coded by ATP4A and ATP12A) are overexpressed in human and murine pancreatic cancer and that we can target them specifically with proton pump inhibitors (PP...

Endoscopy DOI: 10.1055/a-1104-5245In Europe at present, but also in 2040, 1 in 3 cancer-related deaths are expected to be caused by digestive cancers. Endoscopic technologies enable diagnosis, with relatively low invasiveness, of precancerous conditions and early cancers, thereby improving patient survival. Overall, endoscopy capacity must be adjusted to facilitate both effective screening programs and rigorous control of the quality assurance and surveillance systems required. 1 For average-risk populations, ESGE recommends the implementation of organized population-based screening programs for colorectal cancer, based...

Conclusions Lynch syndrome should be suspected in families with familial pancreatic cancer, even in the absence of colon cancers. Specifically, our observation supports the association between the MSH6 c.2194C>T pathogenic variant and extracolonic tumours and it suggests that MSH6 pathogenic variants are associated with familial pancreatic cancer more frequently than assumed.
