Degradation of Hydrocarbons and Lignin-like compounds by Alcaligenes sp. strain 3k isolated from Ilorin
The primary goal of this study was to isolate hydrocarbon-degrading organisms and assess their ability to bioremediate petroleum-contaminated soil and water. Nigeria is one of the major oil producing countries and petroleum contamination is widespread in agricultural soil. Alcaligenes sp. strain 3k was isolated from a kerosene-polluted soil in Ilorin, Nigeria. We also assessed its ability to de...

متن کاملLeukocyte phosphoinositide-3 kinase is required for chemokine-induced, sustained adhesion under flow in vivo
During inflammation, leukocytes roll along the wall of postcapillary venules scanning the surface for immobilized CXCL1, a chemokine that triggers firm adhesion by activating CXCR2 on the neutrophil. PI-3K are signaling molecules important in cellular processes, ranging from cellular differentiation to leukocyte migration. PI-3K can be activated directly by the dimer of heterotrimeric G protein...
متن کاملUse of the Illumina Bovine3K BeadChip in dairy genomic evaluation1
Genomic evaluations using genotypes from the Illumina Bovine3K BeadChip (3K) became available in September 2010 and were made official in December 2010. The majority of 3K-genotyped animals have been Holstein females. Approximately 5% of male 3K genotypes and between 3.7 and 13.9%, depending on registry status, of female genotypes had sire conflicts. The chemistry used for the 3K is different f...
متن کاملInsulinlike growth factor-I signaling in multiple myeloma: downstream elements, functional correlates, and pathway cross-talk.
In multiple myeloma cells, insulinlike growth factor-I (IGF-I) activates 2 distinct signaling pathways, mitogen-activated protein kinase (MAPK) and phosphoinositol 3-kinase (PI-3K), leading to both proliferative and antiapoptotic effects. However, it is unclear through which of these cascades IGF-I regulates these different responses. The present studies identify a series of downstream targets ...
متن کاملConstitutively activated phosphatidylinositol-3 kinase (PI-3K) is involved in the defect of apoptosis in B-CLL: association with protein kinase Cdelta.
In the present study we analyzed the role of phophatidylinositol-3 kinase (PI-3K) in B chronic lymphocytic leukemia (B-CLL) cells. PI-3K is activated by many stimuli and is linked to several different signaling pathways. We demonstrated that inhibition of PI-3K by a specific inhibitor, LY294002, induced apoptosis in B-CLL cells in vitro. This effect was specific for the inhibition of PI-3K beca...
