A tetraspanin-family protein, T-cell acute lymphoblastic leukemia-associated antigen 1, is induced by the Ewing's Sarcoma-Wilms' tumor 1 fusion protein of desmoplastic small round-cell tumor

Recurrent chromosomal translocations in neoplasms often generate hybrid genes that play critical roles in tumorigenesis. Desmoplastic small round-cell tumor (DSRCT) is an aggressive malignancy associated with the chromosomal translocation...

A Salmonella protein causes macrophage cell death by inducing autophagy

Salmonella enterica, the causative agent of food poisoning and typhoid fever, induces programmed cell death in macrophages, a process found to be dependent on a type III protein secretion system, and SipB, a protein with membrane fusion activity that...

Human dendritic cells genetically engineered to express cytosolically retained fragment of prostate-specific membrane antigen prime cytotoxic T-cell responses to multiple epitopes

The ability of two plasmid DNA vaccines to stimulate lymphocytes from normal human donors and to generate antigen-specific responses is demonstrated. The first vaccine (truncated; tPSMA) encodes for only the extracellular domain of prostate-specific...

LPP, a LIM protein highly expressed in smooth muscle

An 80-kDa protein, prominently expressed in smooth muscle, was microsequenced and identified as LPP, the product of the lipoma-preferred partner gene (Petit MMR, Mols R, Schoenmakers EFPM, Mandahl N, and Van de Ven WJM. Genomics 36: 118-129, 1996)....

Phosphorylation of C/EBPalpha inhibits granulopoiesis

CCAAT/enhancer-binding protein alpha (C/EBPalpha) is one of the key transcription factors that mediate lineage specification and differentiation of multipotent myeloid progenitors into mature granulocytes. Although C/EBPalpha is known to induce...

c-Myc degradation induced by DNA damage results in apoptosis of CHO cells

Although tripchlorolide (TC), a compound purified from a Chinese herb Tripterygium Wilfordii Hook, has been demonstrated to be a potent antitumor agent, its mechanisms of action are unknown. The present study shows that TC induces apoptosis of...

Nurr1-RXR heterodimers mediate RXR ligand-induced signaling in neuronal cells

The retinoid X receptor (RXR) is essential as a common heterodimerization partner of several nuclear receptors (NRs). However, its function as a bona fide receptor for endogenous ligands has remained poorly understood. Such a role would depend on the...

Dynamic redistribution of raft domains as an organizing platform for signaling during cell chemotaxis

Spatially restricted activation of signaling molecules governs critical aspects of cell migration; the mechanism by which this is achieved nonetheless remains unknown. Using time-lapse confocal microscopy, we analyzed dynamic redistribution of lipid...

Membrane glucocorticoid receptors (mGCR) are expressed in normal human peripheral blood monunuclear cells and up-regulated after in vitro stimulation and in patients with rheumatoid arthritis

Glucocorticoids mediate their therapeutic actions mostly by genomic effects via cytosolic receptors, but some effects are too rapid to be mediated by changes at the genomic level. The detailed mechanisms of these nongenomic actions are still unclear....

Effect of dicarbonyl modification of fibronectin on retinal capillary pericytes

PURPOSE: To determine effects of alpha-dicarbonyl modification of an extracellular matrix protein on retinal capillary pericyte attachment and viability. METHODS: Primary cultures of bovine retinal pericytes (BRPs) were seeded on either normal...
