The aggressiveness of pancreatic ductal adenocarcinoma (PDA) is characterized by its high metastatic potential and lack of effective therapies, which is the result of a lack of understanding of the mechanisms involved in promoting PDA metastases. We identified Annexin A2 (ANXA2), a member of the Annexin family of calcium-dependent phospholipid binding(More)
After a monocular injection of the cholera toxin B subunit (CTB) into the vitreous chamber of the eye, retinal projections to the medial terminal nucleus (MTN) of the accessory optic system (AOS) were studied in the Japanese monkey. The anterogradely transported tracer was visualized with the peroxidase antibody technique by using an anti-cholera toxin(More)
Intraductal papillary mucinous neoplasms (IPMNs) are one of the three known curable precursor lesions of invasive pancreatic ductal adenocarcinoma, an almost uniformly fatal disease. Cell lines from IPMNs and their invasive counterparts should be valuable to identify gene mutations critical to IPMN carcinogenesis, and permit high-throughput screening to(More)
Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy, with most patients facing an adverse clinical outcome. Aberrant Notch pathway activation has been implicated in the initiation and progression of PDAC, specifically the aggressive phenotype of the disease. We used a panel of human PDAC cell lines as well as patient-derived PDAC xenografts to(More)
PURPOSE It is still technically difficult to collect high purity cancer cells from tumor tissues, which contain noncancerous cells. We hypothesized that xenograft models of NOG mice expressing enhanced green fluorescent protein (eGFP), referred to as NOG-EGFP mice, may be useful for obtaining such high purity cancer cells for detailed molecular and cellular(More)
A 39-y-old man, who had an episode of pancreatic bleeding due to chronic pancreatitis, received total pancreatectomy with islet autotransplantation (TP with IAT). Intraoperative ultrasound (US) examination was done to detect transplanted islets and evaluate the quality of US imaging. Islet isolation from the resected total pancreas was performed and(More)
Cholangiocarcinoma is an aggressive malignant tumor originating from intrahepatic or extrahepatic bile ducts. Its malignant phenotypes may be assumed by cancer stem cells (CSC). Here, we demonstrate that CD274 (PD-L1), known as an immunomodulatory ligand, has suppressive effects on CSC-related phenotypes of cholangiocarcinoma. Using two human(More)
Familial pancreatic cancer (FPC) is broadly defined as two first-degree-relatives with pancreatic cancer (PC) and accounts for 4%-10% of PC. Several genetic syndromes, including Peutz-Jeghers syndrome, hereditary pancreatitis, hereditary breast-ovarian cancer syndrome (HBOC), Lynch syndrome, and familial adenomatous polyposis (FAP), also have increased(More)
BACKGROUND The prognosis for pancreatic cancer remains dismal because many patients are diagnosed with unresectable cancer at the initial diagnosis. Recently, conversion surgery was reported as an effective treatment for initially unresectable pancreatic cancer with a favorable response to non-surgical treatment lasting over 240 days. Here, we describe a(More)
BACKGROUND Undifferentiated embryonal sarcoma of the liver (UESL) is a rare malignant mesenchymal tumor that usually occurs in children and is rarely diagnosed in adults. CASE PRESENTATION Here, we describe the case of a 65-year-old woman who presented with a huge cystic lesion in the liver. Laboratory studies performed on admission showed modest(More)
