Diabetes is a complex, multifactorial group of metabolic diseases characterized by chronic hyperglycaemia due to pancreatic beta-cell dysfunction and/or loss. It is characterized by an asymptomatic and highly variable prodromic phase, which renders diabetes mellitus difficult to be predicted with sufficient accuracy. Despite several efforts in the identification and standardization of newly trustable. Biomarkers able to predict and follow-up diabetes and to specifically subtype its different forms, few of them have proven of clinical utility...

Pancreatic cancer is one of the most lethal types of malignant tumours, commonly diagnosed at an advanced stage. The only curative treatment for this fatal disease is surgery and early diagnosis is the key to a better outcome and prognosis. In this case report we present a 57-year-old woman presenting to the emergency room with abdominal pain and weight loss. Computer Tomography (CT) imaging showed a rupture of the main pancreatic duct and a peri-pancreatic fluid collection with no evidence of a pancreatic mass...

BACKGROUND: The International Study Group on Pancreatic Surgery has stated that at least 12 lymph nodes should be evaluated for staging of pancreatic cancer. The aim of this population-based study was to evaluate whether the number of positive lymph nodes refines staging. METHODS: Patients who underwent pancreatectomy for stage I-II pancreatic cancer between 2004 and 2012 were identified from the Surveillance, Epidemiology, and End Results database. The predictive value of the number of positive lymph nodes for survival was assessed by generalized receiver operating characteristic (ROC) curve analysis and propensity score-adjusted Cox regression analysis...

Glycolysis is a typical conduit for energy metabolism in pancreatic cancer (PC) due to the hypoxic microenviroment. Lactate dehydrogenase A (LDHA) catalyzes the conversion of pyruvate to lactate and is considered to be a key checkpoint of anaerobic glycolysis. The aim of the present study was to explore the mechanism of interactions between hypoxia, HIF-1/2α and LDHA, and the function of LDHA on PC cells by analyzing 244 PC and paratumor specimens. It was found that LDHA was over-expressed and related to tumor stages...

Pancreatic cancer remains one of the deadliest malignancies in the world. Inflammatory response and tumor environment are thought to play a major role in its pathogenesis. Knowledge on TLR expression and impact on patient survival in pancreatic cancer is limited. The study's aim was to clarify the role of different TLRs in pancreatic cancer. TLR2, TLR4, and TLR9 expression was investigated in 65 surgically resected pancreatic ductal adenocarcinoma specimens by immunohistochemistry. The association between TLR expression, clinical parameters, and local inflammatory response to the tumor was assessed using chi-square test...

The incidence of pancreatic cancer (PC) is rising in parallel with the deaths caused by this malignant disease largely due to limited improvement in current treatment strategies. In spite of aggressive PC research, for the past three decades, there has been no significant improvement in the five-year survival for this cancer. Like many other cancers, it takes several years for normal pancreatic cells to transform into pancreatic precursor lesions and to further progress into invasive carcinoma. Hence there is a scope for development of chemoprevention strategies to inhibit/delay/prevent progression of this disease into an advanced stage cancer...

BACKGROUND: BRCA1/BRCA2 germ line (GL) mutation carriers with pancreatic adenocarcinoma (PDAC) may have distinct outcomes. We recently described an apparent more favourable prognosis of surgically resected BRCA-associated PDAC patients in a single-arm, uncontrolled, retrospective study. However, the prognostic impact of GL BRCA1/2 mutations in surgically resected PDAC has not been compared with a matched control population. METHODS: A larger multi-centre, case-control retrospective analysis was performed...

Thrombotic microangiopathy syndromes consist of a collection of disorders with a varied etiology that share common clinical and pathological features. Although thrombotic microangiopathy is rare, it is associated with significant morbidity and mortality. Without early recognition and intervention, the prognosis of the disease is poor. This report illustrates the case of a 56-year-old man with advanced-stage metastatic pancreatic cancer who presented with hemolytic uremic syndrome associated with gemcitabine use...

BACKGROUND: Because long non-coding RNA ATB (activated by TGF-β) is dysregulated in many cancers, we performed a meta-analysis to determine its prognostic potential in malignant tumors. METHODS: We searched electronic databases, including PubMed, Medline, OVID, Cochrane Library and Web of Science from inception until November 15, 2016 and identified eight studies with 818 cancer patients for the meta-analysis. We analyzed the hazard ratios (HRs) and 95% confidence intervals (CIs) to determine the relationship between lncRNA-ATB expression and overall survival (OS), recurrence -free survival (RFS), disease-free survival (DFS)...

Reprogramming of differentiated cells into induced pluripotent stem cells has been recently achieved in vivo in mice. Telomeres are essential for chromosomal stability and determine organismal life span as well as cancer growth. Here, we study whether tissue dedifferentiation induced by in vivo reprogramming involves changes at telomeres. We find telomerase-dependent telomere elongation in the reprogrammed areas. Notably, we found highly upregulated expression of the TRF1 telomere protein in the reprogrammed areas, which was independent of telomere length...
