Metastatic lesion of the pancreas originated from other organs is uncommon. The aim of this report was to evaluate the outcome of surgery in patients with isolated metastases to the pancreas. Nine patients underwent pancreatic resection for metastatic malignant disease from 2000 to 2015 at the Department of Gastroenterological Surgery of the Kumamoto University Hospital. The primary lesion was renal cell carcinoma in 7 cases, colon cancer in 1 and malignant melanoma in 1. The median interval from the initial operation to pancreatic resection was 138 months...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. Chemokines play important roles in the progression of many malignancies; however, the role of chemokine receptor expression in clinical cases of PDAC is unclear. Moreover, little is known about DARC, a decoy receptor of CXC chemokines, in the regulation of tumor progression. METHODS: Functions of chemokine receptors were evaluated using surgical specimens collected from PDAC patients, and PDAC cell lines...

Reprogramming cell fates towards pluripotent stem cells and other cell types has revolutionized our understanding of cellular plasticity. During the last decade, transcription factors and microRNAs have become powerful reprogramming factors for modulating cell fates. Recently, many efforts are focused on reprogramming cell fates by non-viral and non-integrating chemical approaches. Small molecules not only are useful in generating desired cell types in vitro for various applications, such as disease modeling and cell-based transplantation, but also hold great promise to be further developed as drugs to stimulate patients' endogenous cells to repair and regenerate in vivo...

Global cancer incidence and mortality rates are high and increasing. Thus, it is imperative to find novel solutions to preventing cancer incidence and treating it at an affordable yet efficacious manner. The solar UVB-vitamin D-cancer hypothesis was first proposed in 1980 based on a geographical ecological study. Since then, numerous ecological and observational studies as well as studies of mechanisms have provided support for the hypothesis. However, observational studies have not provided consistent support, in part due to using a single blood draw from any season to use for serum 25-hydroxyvitamin D [25(OH)D] concentration in prospective studies with long follow-up times...

Diabetes is a complex, multifactorial group of metabolic diseases characterized by chronic hyperglycaemia due to pancreatic beta-cell dysfunction and/or loss. It is characterized by an asymptomatic and highly variable prodromic phase, which renders diabetes mellitus difficult to be predicted with sufficient accuracy. Despite several efforts in the identification and standardization of newly trustable. Biomarkers able to predict and follow-up diabetes and to specifically subtype its different forms, few of them have proven of clinical utility...

Pancreatic cancer (PC) is a highly lethal disease due to extensive metastatic lesions. Accumulating evidence suggests that miR-675-5p plays different roles in metastasis through the regulation of epithelial to mesenchymal (EMT) and the mesenchymal to epithelial transitions (MET) in different cancers. ZEB1 promotes the EMT process by controlling the expression of E-cadherin and may have a reciprocal regulation with Ubiquilin1 (UBQLN1) and mir-200 family in cancer progression. In the present study, we showed that decreased expression of miR-675-5p is associated with the enhanced cell proliferation and survival of PC cells, while the increased expression of mir-675-5p shows the opposite one...

PURPOSE: Interferon-induced protein with tetratricopeptide repeats 3 (IFIT3) gene from IFITs family is one gene among hundreds of IFN-stimulated genes. The potential role of IFIT3 in cancer is scarcely understood. In addition, the clinical relevance of IFIT3 is not yet known in pancreatic ductal adenocarcinoma (PDAC). We evaluated the prognostic significance of this gene in PDAC patients. METHODS: The expression of IFIT3 was analyzed in pancreatic cancer cell lines with different metastatic potential (FG and L3...

PURPOSE: The GEST study showed non-inferiority of S-1 but not superiority of gemcitabine plus S-1 (GS) to gemcitabine alone for overall survival with the data by the cut-off date of 31st July in 2010 for chemo-naïve patients with advanced pancreatic cancer. We considered it important to determine whether S-1 maintains non-inferiority after a long-term follow-up in the GEST study and to obtain a firm positive conclusion. In addition, it may be an interesting challenge to explore the efficacious profile of GS in the long-term follow-up study...

There is a national trend to refer patients requiring complex oncologic surgery to tertiary high-volume cancer centers. However, this presents major access challenges to Hawai'i patients seeking care. The purpose of this study is to demonstrate that complex oncologic surgery can be safely performed at community hospitals like those in Hawai'i. From July 2007 to December 2014, 136 patients underwent complex oncologic procedures at a community hospital in Hawai'i by a single general surgeon. Cases included esophagogastric, hepatobiliary, pancreatic, rectal, and retroperitoneal resections...

Pancreatic stellate cells (PSCs) were identified in the early 1980s, but received much attention after 1998 when the methods to isolate and culture them from murine and human sources were developed. PSCs contribute to a small proportion of all pancreatic cells under physiological condition, but are essential for maintaining the normal pancreatic architecture. Quiescent PSCs are characterized by the presence of vitamin A laden lipid droplets. Upon PSC activation, these perinuclear lipid droplets disappear from the cytosol, attain a myofibroblast like phenotype and expresses the activation marker, alpha smooth muscle actin...

: Hepatocellular carcinoma (HCC) is rated as the fifth most common malignancy and third in cancer related deaths worldwide. Statins, HMG-CoA reductase inhibitors, are potent cholesterol lowering drugs and recent epidemiological evidence suggests that statins prevent aggressive HCC development. Previous experiments revealed that statins downregulate phosphorylated Akt (pAkt). Here, it is demonstrated that atorvastatin decreases nuclear pAkt levels in pancreatic and lung cancer cell lines within minutes and this rapid effect is mediated by the purinergic P2X receptors...

Pancreatic cancer is the fourth most common cause of cancer mortality worldwide. Furthermore, patients with pancreatic cancer experience limited benefit from current chemotherapeutic approaches because of drug resistance. Therefore, an effective therapeutic strategy for patients with pancreatic cancer is urgently required. Deguelin is a natural chemopreventive drug that exerts potent antiproliferative activity in solid tumors by inducing cell death. However, the molecular mechanisms underlying this activity have not been fully elucidated...

AIMS: GSK-3β is a serine/threonine kinase involved in glycogen metabolism, cell cycle progression, differentiation, embryogenesis, migration, metabolism, survival and cellular senescence. Its main biological function is to inhibit β-catenin by sequestration and promotion of its proteasomal degradation in the Wnt canonical pathway, however GSK-3β interacts with multiple signaling pathways and aberrant expression of the enzyme was reported in many solid neoplasms. This study aimed to investigate the biological relevance of GSK-3β in classical Hodgkin Lymphomas (cHL)...

Paclitaxel (PTX) is a effectively chemotherapeutic agent which is extensively able to treat the non-small cell lung, pancreatic, breast and other cancers. But it is a practically insoluble drug with water solubility less than 1 µg/mL, which restricts its therapeutic application. To overcome the problem, hyaluronic acid-complexed paclitaxel nanoemulsions (HPNs) were prepared by ionic complexation of paclitaxel (PTX) nanoemulsions and hyaluronic acid (HA) to specifically target non-small cell lung cancer. HPNs were composed of DL-α-tocopheryl acetate, soybean oil, polysorbate 80, ferric chloride, and HA and fabricated by high-pressure homogenization...

The reaction of [Ru(CO)6Cl2], 1, with N[combining low line](3)-methylbenzimidazole (MBI) and 5,6-dimethylbenzimidazole (DMBI) afforded two new complexes with the general formula fac-[Ru(II)(CO)3Cl2L], L = MBI (2) or DMBI (4). Crystals of cis,trans-[Ru(II)(CO)2Cl2(N[combining low line](3)-MBI)2], 3, were also obtained from the mother liquor that produced 2. In the presence of water, the dissociation of Ru-N, Ru-Cl and Ru-CO bonds occurred as a function of time, water content and pH.

It has been reported that p21-activated kinase 4 (PAK4) is amplified in pancreatic cancer tissue. PAK4 is a member of the PAK family of serine/threonine kinases, which act as effectors for several small GTPases, and has been specifically identified to function downstream of HGF-mediated c-Met activation in a PI3K dependent manner. However, the functionality of PAK4 in pancreatic cancer and the contribution made by HGF signalling to pancreatic cancer cell motility remain to be elucidated. We now find that elevated PAK4 expression is coincident with increased expression levels of c-Met and the p85α subunit of PI3K...
