PURPOSE We have previously shown that a transcriptome is found in saliva and subpanels of these mRNAs can be used as oral cancer biomarkers. In this study, we measured the presence of microRNAs (miRNA) in saliva and determined their potential as an additional set of oral cancer biomarkers. EXPERIMENTAL DESIGN A total of 314 miRNAs were measured using(More)
PURPOSE Oral fluid (saliva) meets the demand for noninvasive, accessible, and highly efficient diagnostic medium. Recent discovery that a large panel of human RNA can be reliably detected in saliva gives rise to a novel clinical approach, salivary transcriptome diagnostics. The purpose of this study is to evaluate the diagnostic value of this new approach(More)
Cigarette smoking is a major risk factor for head and neck cancer, and individuals who continue to smoke past diagnosis and treatment are at elevated risk for further disease. In a randomized controlled trial, a state of the art provider-delivered smoking cessation intervention was compared to a usual care advice control condition. The intervention(More)
OBJECTIVE To further understanding of treatment of papillary thyroid carcinoma (PTC). DESIGN The Surveillance, Epidemiology, and End Results Program database was searched for patients who had undergone surgery for PTC. SETTING Areas covered by Surveillance, Epidemiology, and End Results population-based registries. PATIENTS Patients who had undergone(More)
Neuroblastoma is a childhood solid tumor composed of primitive cells derived from precursors of the autonomic nervous system. This neoplasm has the highest rate of spontaneous regression of all cancer types and has been noted to undergo spontaneous and chemically induced differentiation into elements resembling mature nervous tissue. As such, neuroblastoma(More)
BACKGROUND Oral cancer is the sixth most common cancer with a 5-year survival rate of approximately 60%. Presently, there are no scientifically credible early detection techniques beyond conventional clinical oral examination. The goal of this study is to validate whether the seven mRNAs and three proteins previously reported as biomarkers are capable of(More)
Purpose: Inflammatory cytokines have been implicated in the progression of head and neck squamous cell carcinoma (HNSCC). Herein we investigate the mechanisms by which interleukin-1β (IL-1β) might contribute to Epithelial-Mesenchymal Transition (EMT) in HNSCC. Experimental Design: We evaluated the effect of IL-1β on the molecular events of EMT in surgical(More)
We have tested the ability of various compounds to raise intracellular cyclic AMP (cAMP) levels and, either alone or in combination with retinoic acid (RA), to promote differentiation of two "RA-resistant" sublines of LA-N-5 human neuroblastoma cells, designated LA-N-5HP and LA-N-5R9. Direct activation of adenylate cyclase by forskolin and cholera toxin(More)
Because of anatomical deformity, trismus, or for other reasons, it may on occasion be impossible to visualize a larynx by the usual laryngoscopy methods. Such difficulties in patients who have paralytic dysphonia may also make it impossible to effect improved vocal cord closure by the usual techniques of Teflon injection. We have applied a new technique,(More)
The action of dichloroacetate (DCA) on pyruvate dehydrogenase (PDH) activity of rat brain has been studied in vitro and in vivo. In a crude brain mitochondrial fraction, DCA inhibits PDH kinase and in rat brain slices this compound increases PDH activity and stimulates glucose oxidation. In the whole animal, intraperitoneal injection of DCA causes(More)
