MicroRNAs (miRNAs) represent a class of small non‑coding RNAs regulating gene expression by inducing the degradation of RNA or interfering with translation. Aberrant miRNA expression has been described in several types of cancer in humans. In the present study, it was demonstrated that miR‑145 is downregulated in pancreatic cancer tissues and the Panc‑1(More)
Pancreatic cancer has one of the highest mortality rates among malignant tumors and is characterized by rapid invasion, early metastasis and chemoresistance. X-linked inhibitor of apoptosis (XIAP) and survivin are two of the most important members of the IAP family. Previous studies have shown that XIAP and survivin were overexpressed in pancreatic cancer(More)
The aim of this study was to investigate the inhibitor of apoptosis proteins survivin and XIAP in pancreatic cancer by determining their biological characteristics and expression. XIAP and survivin are potential therapeutic targets for pancreatic cancer, and elucidating their association with cell proliferation and apoptosis may lead to the development of(More)
The majority of patients with pancreatic cancer are resistant to gemcitabine. One of the mechanisms involved is the anti-apoptotic ability of these cells. The median lethal dose (LD50) of gemcitabine for PANC-1 cells was higher than that for Mia PaCa-2 cells and the former had higher nuclear factor-κB (NF-κB) and X-linked(More)
AIM To determine whether lentivirus-mediated shRNA targeting the X-linked inhibitor of apoptosis protein (XIAP) gene could be exploited in the treatment of pancreatic cancer. METHODS Human pancreatic cancer cells Panc-1, Mia-paca2, Bxpc-3 and SW1990, infected with lentivirus, were analyzed by real-time polymerase chain reaction (PCR). Western blotting was(More)
The present study reports the cloning and sequencing of lac2 from Bacillus subtilis. The gene is composed of 1542 bp and encodes a 514-amino acid protein. The gene has 86% homology with a published laccase with GeneID 936023. The lac2 gene was deposited in GenBank as a new nucleotide sequence. This new sequence was cloned into the multiple cloning site of(More)
