Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignancies with limited survival rate. Roles for peptidylarginine deiminases (PADs) have been studied in relation to a range cancers roles epigenetic regulation (including histone modification and microRNA regulation), cancer invasion, extracellular vesicle (EV) release. Hitherto though, knowledge on PADs PDAC limited. In c...

BACKGROUND SIRT 1, as a class III histone deacetylase (HDAC), is implicated in the initiation and progression of malignancies. However, the association of SIRT 1 with tumorigenesis or progression of pancreatic ductal adenocarcinoma (PDAC) is not clear. MATERIAL AND METHODS In our study we investigated SIRT 1 expression in PDAC samples and evaluated the association of SIRT 1 level with the clini...

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 expre...

Objective response rates to standard chemotherapeutic regimens remain low in pancreatic cancer. Subpopulations of cells have been identified in various solid tumors which express stem cell-associated markers and are associated with increased resistance against radiochemotherapy. We investigated the expression of stem cell genes and markers of epithelial-mesenchymal transition in pancreatic canc...

Unconventional Food Plants (PANC) are increasingly sought after by consumers looking for healthy and nutritious food. However, its use is still restricted due to little knowledge about the species. The aim of this research was map PANC species in Nova Camapuã Settlement - DF, as well evaluate farmers their families type plant. For this, a semi-structured questionnaire, interview, guided walk, p...

The enzyme pantothenate synthetase, PanC, is an attractive drug target in Mycobacterium tuberculosis. It is essential for the in vitro growth of M. tuberculosis and for survival of the bacteria in the mouse model of infection. PanC is absent from mammals. We developed an enzyme-based assay to identify inhibitors of PanC, optimized it for high-throughput screening, and tested a large and diverse...

Objective(s): Pyocyanin, a blue-green pigment produced by Pseudomonas aeruginosa, interferes with host redox cycles, which can lead to generation of reactive oxygen species and progressive cellular oxidative damage. The aim of this study was to assess the influence of pyocyanin on human pancreatic cancer cell line.Materials and Methods: Polymerase Chain Reaction (PCR) was applied to confirm the...

Photodynamic therapy (PDT) that uses the second generation photosensitizer, verteporfin (VP), is a developing therapy for pancreatic cancer. The optimal timing of light delivery related to VP uptake and distribution in pancreatic tumors will be important information to obtain to improve treatment for this intractable disease. In this work we examined uptake and distribution of VP in two orthoto...

Plumbagin (PLB), an active naphthoquinone compound, has shown potent anticancer effects in preclinical studies; however, the effect and underlying mechanism of PLB for the treatment of pancreatic cancer is unclear. This study aimed to examine the pancreatic cancer cell killing effect of PLB and investigate the underlying mechanism in human pancreatic cancer PANC-1 and BxPC-3 cells. The results ...
