Killer cell lectin-like receptor G1 (KLRG1) is one of several inhibitory killer cell lectin-like receptors expressed by NK cells and T lymphocytes, mainly CD8(+) effector/memory cells that can secrete cytokines but have poor proliferative capacity. Using multiparameter flow cytometry, we studied KLRG1 expression on CD8(+) T cells specific for epitopes of(More)
Dibenzoylmethane (DBM), a minor beta-diketone constituent of licorice and sunscreens, has been shown to exhibit anti-neoplastic effects in chemically induced skin and mammary cancers in several animal models. To date, no mechanism for the growth inhibitory effects of DBM on prostate cancer cells has been proposed. In this study, we examined the effects of(More)
Glioblastoma (GBM) is a highly aggressive primary brain tumor with a poor prognosis. Despite aggressive therapy with surgery, radiotherapy, and chemotherapy, nearly all patients succumb to disease within 2 years. Several studies have supported the presence of stem-like cells in brain tumor cultures that are CD133-positive, are capable of self-renewal, and(More)
BACKGROUND SF1126 is a peptidic pro-drug inhibitor of pan-PI3K/mTORC. A first-in-human study evaluated safety, dose limiting toxicities (DLT), maximum tolerated dose (MTD), pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of SF1126, in patients with advanced solid and B-cell malignancies. PATIENTS AND METHODS SF1126 was administered IV days 1 and(More)
BACKGROUND The androgen receptor (AR) plays an important role in the development and progression of prostate cancer. Functional AR expression persists in most cases of hormone-refractory prostate cancer and may play a role clinically in the progression from hormone-responsive to hormone-refractory or advanced prostate cancer. In order to combat the(More)
OBJECTIVES Preoperative C-reactive protein (CRP) predicts metastasis and mortality in localized renal cell carcinoma (RCC). However, the predictive potential of after resection of localized RCC remains unclear. Therefore, we assessed the absolute ability of postoperative CRP to predict metastases and mortality as a continuous variable. METHODS Patients(More)
PURPOSE A randomized phase II trial (E1200) was designed to assess toxicities and surgical resection rates in two neoadjuvant gemcitabine-based chemoradiation regimens in patients with borderline resectable pancreatic cancer. The trial was terminated early due to poor accrual. PATIENTS AND METHODS Patients with borderline resectable adenocarcinomas of the(More)
PURPOSE Sleep/wake disturbances are prevalent in patients with advanced cancer, but 24-hour polysomnography (PSG) examinations of these patterns have not been undertaken. The purpose of this study was to describe these sleep/wake patterns using continuous PSG and to explore relationships with selected demographic and clinical variables. PATIENTS AND(More)
2558 Background: SF1126 is composed of the pan PI3K inhibitor LY294002 conjugated to an RGD targeting peptide. It is designed to increased solubility and binding to integrins expressed on tumor vasculature. This targeted prodrug enhances tumor delivery of the active inhibitor, improving antitumor efficacy and tolerability in xenograft models. LY294002(More)
PURPOSE/OBJECTIVE To investigate the effect of the enforced expression of p29Bcl-xL or its loop deletional mutant, p18Bcl-xLdelta, on irradiation-induced apoptosis and cell-cycle distribution of HL-60 cells. MATERIALS & METHODS We compared the irradiation-induced molecular cascade of apoptosis in control human AML HL-60/neo versus Bcl-xL overexpressing(More)
