TL;DR: Caspase 8 acts as a tumor suppressor in neuroblastomas with amplification of the oncogene MYCN and is silenced through DNA methylation as well as through gene deletion.
Abstract: Caspase 8 is a cysteine protease regulated in both a death-receptor-dependent and -independent manner during apoptosis. Here, we report that the gene for caspase 8 is frequently inactivated in neuroblastoma, a childhood tumor of the peripheral nervous system. The gene is silenced through DNA methylation as well as through gene deletion. Complete inactivation of CASP8 occurred almost exclusively in neuroblastomas with amplification of the oncogene MYCN. Caspase 8-null neuroblastoma cells were resistant to death receptor- and doxorubicin-mediated apoptosis, deficits that were corrected by programmed expression of the enzyme. Thus, caspase 8 acts as a tumor suppressor in neuroblastomas with amplification of MYCN.

TL;DR: The structure and properties of p65 suggest that it may have a role in mediating membrane interactions during synaptic vesicle exocytosis, and a novel homology between a cellular protein and the regulatory domain of protein kinase C is reported.
Abstract: NEUROTRANSMITTERS are released at synapses by the Ca2+-regulated exocytosis of synaptic vesicles, which are specialized secretory organelles that store high concentrations of neurotransmitters1,2. The rapid Ca2+-triggered fusion of synaptic vesicles is presumably mediated by specific proteins that must interact with Ca2+ and the phospholipid bilayer. We now report that the cytoplasmic domain of p65, a synaptic vesicle-specific protein3 that binds calmodulin4 contains an internally repeated sequence that is homologous to the regulatory C2-region of protein kinase C (PKC)5. The cytoplasmic domain of recombinant p65 binds acidic phospholipids with a specificity indicating an interaction of p65 with the hydrophobic core as well as the headgroups of the phospholipids. The binding specificity resembles PKC, except that p65 also binds calmodulin, placing the C2-regions in a context of potential Ca2+-regulation that is different from PKC. This is a novel homology between a cellular protein and the regulatory domain of protein kinase C. The structure and properties of p65 suggest that it may have a role in mediating membrane interactions during synaptic vesicle exocytosis.

TL;DR: This paper performed genome-wide DNA copy number analyses on matched diagnosis and relapse samples from 61 pediatric patients with acute lymphoblastic leukemia (ALL) to explore the genetic basis of relapse, and found that the cells responsible for relapse are ancestral to the primary leukemia cells.
Abstract: Most children with acute lymphoblastic leukemia (ALL) can be cured, but the prognosis is dismal for the minority of patients who relapse after treatment. To explore the genetic basis of relapse, we performed genome-wide DNA copy number analyses on matched diagnosis and relapse samples from 61 pediatric patients with ALL. The diagnosis and relapse samples typically showed different patterns of genomic copy number abnormalities (CNAs), with the CNAs acquired at relapse preferentially affecting genes implicated in cell cycle regulation and B cell development. Most relapse samples lacked some of the CNAs present at diagnosis, which suggests that the cells responsible for relapse are ancestral to the primary leukemia cells. Backtracking studies revealed that cells corresponding to the relapse clone were often present as minor subpopulations at diagnosis. These data suggest that genomic abnormalities contributing to ALL relapse are selected for during treatment, and they point to new targets for therapeutic intervention.

TL;DR: Cases of disease caused by H5N1 and transmission of the virus among migratory geese populations in western China are described and this outbreak may help to spread the virus over and beyond the Himalayas.
Abstract: A worrying development could help to spread this dangerous virus beyond its stronghold in southeast Asia. The highly pathogenic H5N1 influenza virus has become endemic in poultry in southeast Asia since 2003 and constitutes a major pandemic threat to humans1. Here we describe cases of disease caused by H5N1 and transmission of the virus among migratory geese populations in western China. This outbreak may help to spread the virus over and beyond the Himalayas and has important implications for developing control strategies.
