BACKGROUND Some clinicians have argued that combining pancreatic and portomesenteric venous resection could improve the rates of long-term survival. However, whether resection of the portosplenomesenteric vein could provide an acceptable survival benefit to patients with pancreatic cancer involving the portosplenomesenteric system remains controversial. The(More)
Post-transcriptional modification of p53 by phosphorylation has been proposed as an important mechanism of p53 stabilization and functional regulation. However, little is known about the phosphorylation state of mutant p53 protein overexpressed in human tumors. We evaluated immunohistochemically the p53 phosphorylation state of Ser392 and Ser15 sites in 44(More)
Recently, autoimmune pancreatitis (AIP) has been reported with a variety of extra-pancreatic manifestations and infiltration of IgG4-positive cells into the affected organs. We report herein two cases with prostatitis. One was seen in a patient with typical AIP, and the other was observed without any clinical manifestation of AIP. Serum IgG4 levels were(More)
BACKGROUND We report a case of a 33-year-old man who presented with immunoglobulin (Ig)G4-related disease (IgG4-RD) forming a pseudotumor in the left paratesticular region during oral administration of corticosteroid for Wells syndrome, which involves cellulitis with eosinophilia. CASE PRESENTATION The patient was introduced to our institution from a(More)
Host defense mechanisms play important roles in suppressing the development and growth of tumors. It is known that S-100 protein-positive immature dendritic cells (S100DC), as antigen presenting cells (APC), and macrophages have roles in the immune responses to tumor growth. Mediators such as nitric oxide are also important in the surveillance against(More)
MicroRNAs contribute to the pathogenesis of certain diseases and may serve as biomarkers. We analyzed glomerular microRNA expression in B6.MRLc1, which serve as a mouse model of autoimmune glomerulonephritis. We found that miR-26a was the most abundantly expressed microRNA in the glomerulus of normal C57BL/6 and that its glomerular expression in B6.MRLc1(More)
Nodular fasciitis is a benign proliferative lesion composed of fibroblast-like cells that affects various sites in the body. We describe a patient with nodular fasciitis in the mesentery, encountered during laparotomy for the treatment of ascending colon cancer. The nodular fasciitis in our patient resembled peritoneal dissemination of malignancy on(More)
p53 has been called the "cellular gatekeeper" and the "genome guard," because in response to exposure to DNA-damaging agents, it induces cell-cycle arrest in G1 or apoptosis and also directly affects DNA replication. Multiple mechanisms regulate p53 activity and posttranslational modification, including multisite phosphorylation of wild-type p53, in(More)
Post-transcriptional modification of p53 by phosphorylation has been proposed to be an important mechanism of p53 stabilization and functional regulation. Phosphorylation of p53 Ser392, in particular, activates specific DNA binding functions by stabilizing p53 tetramer formation. This study evaluated the relationship between p53 Ser392 phosphorylation and(More)
PURPOSE It is known that a common p53 polymorphism, encodingeither proline (Pro) or arginine (Arg) at residue 72, produces marked change in the structure of p53. Furthermore, the Arg72-containing allele is preferentially mutated and retained in various human tumors, suggesting that polymorphic residue within p53 modifies mutant behavior. We studied to(More)
