SIRT1 and other NAD-dependent deacetylases have been implicated in control of cellular responses to stress and in tumorigenesis through deacetylation of important regulatory proteins, including p53 and the BCL6 oncoprotein. Hereby, we describe the identification of a compound we named cambinol that inhibits NAD-dependent deacetylase activity of human SIRT1 and SIRT2. Consistent with the role of...

characteristics of uridineand methyl-labeled low molecular weight RNA (4S and. 5S) of human lymphoblasts from Burkitt lymphoma, infectious mononucleosis, and EB-virus transformed lymphocytes were compared with lymphoblasts from normal donors (cell line) and phytohernagglutinin (PHA)-transformed peripheral blood lymphocytes. No significant differences in these RNA profiles were found between the...

P galactoside binding protein (PGBP) is a novel physiological regulator of the cell cycle secreted by mouse embryo fibroblasts (MEFs) [l]. Addition of PGBP to MEFs has been shown to induce cell cycle arrest. PGBP is a monomeric protein of 134 amino acids long. PGBP's cytostatic effect is independent of its carbohydrate-binding activity and it operates by binding to high affinity receptors on ta...

Nussenzweig and colleagues evaluate genomic instability and germinal center derived lymphomagenesis in mice infected with Plasmodium to recreate some of the hallmark characteristics of Burkitt lymphoma, a form of cancer more common in parts of Africa where malaria is endemic.

BACKGROUND Lymphoma-associated incomplete Miller-Fisher syndrome is very rare. CASE CHARACTERISTICS An 11-year-old boy who initially presented with headache, left ptosis, diplopia and weakness. Neurologic examination indicated left sided ptosis with ophthalmoplegia. OBSERVATIONS Cerebral imaging and cerebrospinal fluid examinations were normal. Magnetic resonance imaging of the abdomen show...

The optimal treatment of advanced sporadic Burkitt lymphoma in adults is still a matter of debate. The salutary results of pediatric therapies did open the road for improving the adult outcome. Between May 1988 and March 2009, 71 consecutive patients-46 adults, 25 children-affected by Burkitt lymphoma/leukemia were treated with the same intensive pediatric protocol alternating vincristine, adri...

Selective serotonin reuptake inhibitors (SSRIs) are the treatment of choice for clinical depression and a range of anxiety-related disorders. They are well tolerated over extended periods with more than 50 million people worldwide benefiting from their use. Here we show that 3 structurally distinct SSRIs--fluoxetine, paroxetine, and citalopram--act directly on Burkitt lymphoma (BL) cells to tri...

Burkitt lymphoma is a highly aggressive B-cell neoplasm. New therapeutic methods are needed to overcome the adverse effect of intensive chemotherapy regimens. Valproic acid and (-)-gossypol are two kinds of chemical compounds used as new anti-tumor drugs in recent years. To investigate the anti-tumor effect of valproic acid and (-)-gossypol, Burkitt lymphoma Namalwa cells were cultured and trea...
