We sequenced eight melanoma exomes to identify new somatic mutations in metastatic melanoma. Focusing on the mitogen-activated protein (MAP) kinase kinase kinase (MAP3K) family, we found that 24% of melanoma cell lines have mutations in the protein-coding regions of either MAP3K5 or MAP3K9. Structural modeling predicted that mutations in the kinase domain(More)
We have identified a novel liver X receptor (LXR) agonist (2) that activates the LXRbeta subtype with selectivity over LXRalpha. LXRbeta selectivity was confirmed using macrophages derived from LXR mutant mice. Despite its selectivity and modest potency, the compound can induce APO-AI-dependent cholesterol efflux from macrophages with full efficacy. Our(More)
Synucleinopathies are a broad class of neurodegenerative disorders characterized by the presence of intracellular protein aggregates containing α-synuclein protein. The aggregated α-synuclein protein is hyperphosphorylated on serine 129 (S129) compared to the unaggregated form of the protein. While the precise functional consequences of S129(More)
During the process of phagocytosis, polymorphonuclear leukocytes (PMN) release lysosomal enzymes into the extracellular medium. When the antibiotic cytochalasin B (CB) is present in the incubation medium along with phagocytable particles, enhanced recovery of enzyme activities from the incubation medium has been observed. These findings have led to the(More)
Salmon calcitonin (sCT), a 32-amino-acid polypeptide, was lipidized by using a reversible aqueous lipidization (REAL) technology. When injected subcutaneously into mice, the AUC of REAL-sCT was four times greater than that of sCT and a similar pattern of reduction in plasma calcium level was observed. The therapeutic effect of REAL-sCT was evaluated in(More)
The Y-box binding protein 1 (YB-1) is a multifunctional protein that affects transcription, splicing, and translation. Overexpression of YB-1 in breast cancers causes cisplatin resistance. The exact mechanism by which YB-1 confers cisplatin resistance is unknown. The aim of the present study was to identify, using mass spectrometry, proteins that interact(More)
When rabbit isolated gastric glands were stimulated via the cyclic AMP pathway, a phosphorylated protein band of about 120 kDa (pp120) was markedly increased in the apical membrane-rich fraction, concomitant with an increase in the amount of H,K-ATPase and the phosphorylation of the cytoskeletal protein ezrin in the same fraction. The cytosolic fraction,(More)
Synergistic molecular vulnerabilities enhancing hypomethylating agents in myeloid malignancies have remained elusive. RNA-interference drug modifier screens identified antiapoptotic BCL-2 family members as potent 5-Azacytidine-sensitizing targets. In further dissecting BCL-XL, BCL-2 and MCL-1 contribution to 5-Azacytidine activity, siRNA silencing of BCL-XL(More)
BACKGROUND Many researchers have expressed concerns about ethical tensions in occupational therapy practice; yet little research has considered this topic from the perspective of students. PURPOSE The purpose of this study was to examine the nature of ethical tensions witnessed or experienced by occupational therapy students during practice education.(More)
