Heparanase is an enzyme that cleaves heparan sulfate and through this activity promotes tumor growth, angiogenesis, invasion, and metastasis in several tumor types. In human breast cancer patients, heparanase expression is associated with sentinel lymph node metastases. However, the precise role of heparanase in the malignant progression of breast cancer is unknown. To examine this, a variant o...

The NEO Personality Inventory-3 (NEO-PI-3) is a modification of the Revised NEO Personality Inventory (NEO-PI-R) designed to be more understandable to adolescents. Data from adults aged 21 to 91 showed that the NEO-PI-3 also functions as well or better than the NEO-PI-R in adults. Age trends from combined adolescent (n = 500) and adult (n = 635) samples confirmed previous cross-sectional findin...

Selective cyclooxygenase-2 (COX-2) inhibitors (coxibs) increase the incidence of cardiovascular and cerebrovascular events. Complete disruption of the murine gene encoding COX-2 (Ptgs2) leads to renal developmental problems, as well as female reproductive anomalies and patent ductus arteriosus of variable penetrance in newborns, thus rendering this genetic approach difficult to compare with cox...

A breakdown in self-tolerance underlies autoimmune destruction of β-cells and type 1 diabetes. A cure by restoring β-cell mass is limited by the availability of transplantable β-cells and the need for chronic immunosuppression. Evidence indicates that inhibiting costimulation through the PD-1/PD-L1 pathway is central to immune tolerance. We therefore tested whether induction of islet neogenesis...

Changes in the outer membrane of apoptotic cells can induce neighboring cells to become phagocytic. Using genetically marked prostate cancer cell lines, we explored the possibility that genetic information might be transferred from an apoptotic cell to a phagocytic neighbor. Neomycin-resistant LNCaP cells that overexpress bcl-2 (LNCaP(bcl-2/neo-r)) were cocultured with hygromycin-resistant LNCa...

BACKGROUND Recently, we reported that low reward dependence, and to a lesser extent, low cooperativeness in the Temperature and Character Inventory (TCI) may be risk factors for treatment-resistant depression. Here, we analyzed additional psychological traits in these patients. METHODS We administered Costa and McCrae's five-factor model personality inventory, NEO Personality Inventory-Revise...
