INTRODUCTION The indications, the extent and type of surgery for intraductal papillary mucinous neoplasm (IPMN) are still controversial. This study aimed to investigate clinical manifestation, individualized surgical treatment, and prognosis of IPMN of pancreas. METHODS The clinical data of 96 IPMN cases treated in our hospital between January 2006 and(More)
Mechanisms leading to acute pancreatitis after a fat-enriched meal combined with excess alcohol are incompletely understood. We have studied the effects of alcohol and fat (VLDL) on pancreatic acinar cell (PAC) function, oxidative stress, and repair mechanisms by pancreatic stellate cells (PSC) leading to fibrogenesis. To do so, PAC (rat) were isolated and(More)
Experimental measurements and analysis of the flight of bats are presented, including kinematic analysis of high-speed stereo videography of straight and turning flight, and measurements of the wake velocity field behind the bat. The kinematic data reveal that, at relatively slow flight speeds, wing motion is quite complex, including a sharp retraction of(More)
Hedgehog (Hh) signaling is crucially involved in tumorigenesis. This study aimed to assess the role of Hh signaling in the regulation of epithelial-mesenchymal transition (EMT), stemness properties and chemoresistance of human pancreatic Panc-1 cancer stem cells (CSCs). Panc-1 cells were transfected with recombinant lentiviral vectors to silence SMO and(More)
INTRODUCTION Pancreatic cancer is an aggressive malignancy with a poor prognosis. The overall 5-year survival rate of pancreatic cancer is less than 5%, and has not improved significantly for years. Further understanding of the molecular carcinogenesis of pancreatic cancer is critical for designing effective ways to treat this type of malignancy. METHODS(More)
Gemcitabine is a standard chemotherapeutic agent for locally advanced and metastatic pancreatic cancer. However, the chemoresistance of pancreatic cancer is the major barrier to efficient chemotherapy. Here, we reported that BRG1, a chromatin modulator, was exclusively overexpressed in human pancreatic ductal adenocarcinoma tissues. BRG1 knockdown inhibited(More)
BACKGROUND Insulin-like growth factor 1 receptor (IGF1R) plays important roles in the progression of pancreatic cancer. However, the underlying mechanism remains unclear. AIMS The purpose of this study was to investigate the effects of IGF1R knockdown on the proliferation, apoptosis and chemosensitivity of pancreatic cancer cells, and explore the possible(More)
H19 is a long noncoding RNA differentially expressed in many tumors and participates in tumorigenesis. This study aimed to investigate the expression and function of H19 in pancreatic ductal adenocarcinoma (PDAC). Pure malignant cells were isolated from frozen sections of 25 PDAC cases by laser captured microdessection, and H19 expression level was detected(More)
Nonalcoholic fatty liver disease (NAFLD) is characterized by a massive accumulation of lipid droplets (LDs). The aim of this study was to determine the function of 17β-hydroxysteroid dehydrogenase-13 (17β-HSD13), one of our newly identified LD-associated proteins in human subjects with normal liver histology and simple steatosis, in NAFLD development. LDs(More)
Hydrogen sulfide (H2S) has emerged as an exciting endogenous gasotransmitter in addition to nitric oxide and carbon monoxide. However, its precise measurement in living cells and animals remains a challenge. In this study, a novel bioluminescence H2S probe was designed and synthesized by modifying the 6'-amino group of d-aminoluciferin into a 6'-azido(More)
