BACKGROUND Current treatment of pancreatic cancer is generally associated with poor prognosis, even if diagnosed early, owing to its aggressive rate of metastasis and non-responsiveness to chemotherapy and radiotherapy. Matrix metalloproteinases (MMPs) have received much attention in recent years

microRNAs (miRNAs) have been proved to be involved in many events of tumor development and progression, including cell proliferation, cell apoptosis, and cell cycle arrest. However, the potential role of miR-144-3p in pancreatic cancer (PC) remains elusive. In this study, we demonstrated that

Quantitative targeted absolute proteomics-based large-scale quantification of proline-hydroxylated α-fibrinogen in plasma for pancreatic cancer diagnosis.

Pancreatic cancer is a devastating disease and early diagnosis and treatment are essential to improve the prognosis. We previously showed that α-fibrinogen containing hydroxylated proline residues at positions 530 and 565 is increased in plasma of pancreatic cancer patients. However, no antibody

Reverse aldol opening renders amides of 3-hydroxyazetidinecarboxylic acids (3-OH-Aze) unstable above pH 8. Aze, found in sugar beet, is mis-incorporated for proline in peptides in humans and is associated with multiple sclerosis and teratogenesis. Aze-containing peptides may be oxygenated by prolyl

Pancreatic cancer mucin from xenografts of SW1990 cells: isolation, characterization, and comparison to colon cancer mucin.

Mucin has been purified from nude mouse xenografts of SW1990 human pancreatic cancer cells. The mucin was eluted at the void volume of Sepharose CL-4B and was of density greater than 1.3 in CsCl gradients. The isolated mucin had a high content of threonine, serine, and proline, with 31% of the amino

BACKGROUND Pancreatic cancer is a deadly disease. Discovery of the mutated genes that cause the inherited form(s) of the disease may shed light on the mechanism(s) of oncogenesis. Previously we isolated a susceptibility locus for familial pancreatic cancer to chromosome location 4q32-34. In this

Pancreatic ductal adenocarcinoma (PDAC) is a fatal disease that shows minimal response to chemotherapy. Genetic changes involved in the progression of PDAC concern genes that encode proteins related to signal transduction networks. This fact reveals the importance in identifying the role and the

Pancreatic ductal adenocarcinomas are highly malignant cancers characterized by extensive invasion into surrounding tissues, metastasis to distant organs, and a limited response to therapy. A main feature of pancreatic ductal adenocarcinomas is desmoplasia, which leads to extensive deposition of

BACKGROUND In malignant diseases, circulating amino acid profiles correlate with organ sites of malignancy. Direct effects of malignant cells on the extracellular amino acid profile are still uncertain. METHODS Free amino acids were measured in serum-free culture media (RPMI-1640) conditioned by two

Molecular characterization of a mucin-type antigen associated with human pancreatic cancer. The DU-PAN-2 antigen.

This work describes the molecular characterization of a human pancreatic cancer-associated antigen defined by a murine monoclonal antibody (DU-PAN-2). DU-PAN-2 antigen was isolated from a pancreatic adenocarcinoma cell line (HPAF) or patient's ascitic fluid, and the antigenic activity was monitored

OBJECTIVE Accumulating evidence suggests that energy imbalance plays a role in pancreatic carcinogenesis. However, it remains unclear whether single-nucleotide polymorphisms (SNPs) in genes regulating energy homeostasis influence pancreatic cancer risk. We investigated this question in a
