The prognosis of pancreatic cancer remains dismal, with little advance in chemotherapy because of its high frequency of chemoresistance. Metformin is widely used to treat type II diabetes, and was shown recently to inhibit pancreatic cancer stem cell proliferation. In the present study, we investigated the role of metformin in chemoresistance of pancreatic cancer cells to gemcitabine, and its p...

Early diagnosis of pancreatic cancer, one of the most deadly cancers with low survival rates, is difficult, and effective biomarkers are urgently needed. Lipopolysaccharide-induced tumor necrosis factor-α factor (LITAF) has been recently proposed as a potential tumor suppressor gene in several types of cancer. Here, we analyzed the biological function of LITAF in pancreatic cancer. The LITAF ge...

Pancreatic cancer is one of the most lethal malignancies and the fourth leading cause of cancer-related deaths worldwide, because of its aggressive and highly metastatic ability even in its early stages. Cancer-associated fibroblasts (CAFs) have been reported to be vital to pancreatic cancer progression via regulating tumorigenesis and metastasis. Studies have shown that CAFs also mediate epith...

Clinical manifestations of pancreatic cancer often do not occur until the cancer has undergone metastasis, resulting in a very low survival rate. In this study, we investigated whether salivary bacterial profiles might provide useful biomarkers for early detection of pancreatic cancer. Using high-throughput sequencing of bacterial small subunit ribosomal RNA (16S rRNA) gene, we characterized th...

Pancreatic cancer remains clinically challenging because of the lack efficient targeted therapies and high aggressiveness. NEDD8 activating enzyme (NAE) plays a critical role in various cellular functions cancers. Herein, we report synthesis, optimization, evaluation new series pyrido[2,3-d]pyrimidin-7(8H)-one derivative as highly selective efficacious NAE inhibitors, enabling rapid degradation...

introduction : pancreatic cancer has not been well studied, especially in developing countries. materials and methods : we studied the variations in genetic mutations in pancreatic adenocarcinoma between moroccan and egyptian populations. the molecular pathology of 30 tumors from a large hospital in casablanca, morocco were examined and compared with the findings of 44 tumors from the gharbiah ...

Purpose: Betulinic acid, a naturally occurring pentacyclic triterpenoid, exhibits potent antitumor activities, whereas the underlying mechanisms remain unclear. In the current study, we sought to determine the role and regulation of lamin B1 expression in human pancreatic cancer pathogenesis and betulinic acid–based therapy. Experimental Design:We used cDNA microarray to identify betulinic acid...

Pancreatic adenocarcinoma is a low-incident but highly mortal disease. It accounts for only 3% of estimated new cancer cases each year but is currently the fourth common cause of cancer mortality. By 2030, it is expected to be the 2(nd) leading cause of cancer death. There is a clear need to diagnose and classify pancreatic cancer at earlier stages in order to give patients the best chance at a...

Radiotherapy represents a major treatment option for patients with pancreatic cancer, but recent evidence suggests that radiation can promote invasion and metastasis of cancer cells. Interactions between cancer cells and surrounding stromal cells may play an important role in aggressive tumor progression. In the present study, we investigated the invasive phenotype of pancreatic cancer cells in...

Mutations in the BRCA2 gene have been implicated in pancreatic cancer susceptibility through studies of high-risk breast and ovarian cancer families. To determine the contribution of mutations in BRCA2 to familial pancreatic cancer, we screened affected probands from 151 high-risk families identified through pancreatic cancer clinics for germ-line BRCA2 mutations. Of these families, 118 had two...
