Haejung Kim, Haein Hwang, Hansoo Lee, Hyo Jeong Hong
Extrahepatic cholangiocarcinoma (ECC), a malignant tumor of biliary origin, has a poor prognosis with limited treatment options. The KRAS oncogene is the most commonly mutated gene in ECC and one of the factors that predicts a poor prognosis and low survival rate. L1 cell adhesion molecule (L1CAM) is expressed in ECC cells and acts as an independent poor prognostic factor in predicting patient survival. In this study we investigate the functional significance of L1CAM in ECC cells with activating KRAS mutation...

Ju Hee Oh, Na Kyung Lee
Despite the importance of the receptor activator of nuclear factor (NF)-kappaB ligand (RANKL)-RANK signaling mechanisms on osteoclast differentiation, little has been studied on how RANK expression is regulated or what regulates its expression during osteoclastogenesis. We show here that insulin signaling increases RANK expression, thus enhancing osteoclast differentiation by RANKL. Insulin stimulation induced RANK gene expression in time- and dose-dependent manners and insulin receptor shRNA completely abolished RANK expression induced by insulin in bone marrow-derived monocyte/ macrophage cells (BMMs)...

BACKGROUND/AIMS: The steroidal aromatase inactivator exemestane blocks estrogen biosynthesis and is thus employed for the prevention and treatment of breast cancer. Exemestane is in part effective by stimulation of suicidal cell death or apoptosis. Side effects of exemestane treatment include anemia. At least in theory, exemestane induced anemia could be secondary to stimulation of suicidal erythrocyte death or eryptosis, characterized by cell shrinkage and cell membrane scrambling with phosphatidylserine translocation to the erythrocyte surface...

Starch is one of the most popular nutritional sources for both human and animals. Due to the variation of its nutritional traits and biochemical specificities, starch has been classified into rapidly digestible, slowly digestible and resistant starch. Resistant starch has its own unique chemical structure, and various forms of resistant starch are commercially available. It has been found being a multiple-functional regulator for treating metabolic dysfunction. Different functions of resistant starch such as modulation of the gut microbiota, gut peptides, circulating growth factors, circulating inflammatory mediators have been characterized by animal studies and clinical trials...

In the present work we provide the first isolation and functional characterization of a RXR orthologue in an annelid species, the Platynereis dumerilii. Using an in vitro luciferase reporter assay we evaluated the annelid receptor ability to respond to ligand 9-cis-retinoic acid, TBT and TPT. Our results show that the annelid RXR responds to 9-cis-retinoic acid and to the organotins by activating reporter gene transcription. The findings suggest a conserved mode of action of the receptor in response to a common signaling molecule and modulation by organotin compounds between vertebrates and Lophotrochozoans...

Fatty acid amide hydrolase (FAAH) has a key role in the control of the cannabinoid signaling, through the hydrolysis of the endocannabinoids anandamide and in some tissues 2-arachidonoylglycerol. FAAH inhibition represents a promising strategy to activate the cannabinoid system, since it does not result in the psychotropic and peripheral side effects characterizing the agonists of the cannabinoid receptors. Here we present the discovery of a novel class of profen derivatives, the N-(heteroaryl)-2-(4-((2-(trifluoromethyl)pyridin-4-yl)amino)phenyl)propanamides, as FAAH inhibitors...

Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA with a 5-year survival rate less than 3% to 5%. Gemcitabine remains as a standard care for PDAC patients. Although protein neddylation is abnormally activated in many human cancers, whether neddylation dysregulation is involved in PDAC and whether targeting neddylation would sensitize pancreatic cancer cells to gemcitabine remain elusive. Here we report that high expression of neddylation components, NEDD8 and NAE1, are associated with poor survival of PDAC patients...
