An investigation was conducted to follow up on the apparent species-dependent toxicity reported for 6-(6-(1-methyl-1H-pyrazol-4-yl)-[1,2,4]triazolo[4,3-b]pyridazin-3-ylthio)quinoline (SGX523), a mesenchymal-epithelial transition factor (c-MET) inhibitor that entered clinical development for the treatment of solid tumors. Patients treated with SGX523 exhibited compromised renal function presumab...

The murine gammaherpesvirus-68 (MHV-68) M11 gene encodes a protein predicted to have limited homology to the bcl-2 family of proteins. Unlike most of the other viral bcl-2 homologues, which have both BH1 and BH2 domains conserved with respect to bcl-2, the M11 protein has a BH1 domain, but apparently lacks a BH2 domain. Transfection of HeLa cells with an epitope-tagged MHV-68 M11 construct show...

Julius Whiston [6] calculated the maximum size of an irredundant generating set for Sn and An by examination of maximal subgroups. Using analogous considerations, we will compute upper bounds to this value for the first two Mathieu groups, M11 and M12. Computational results gave explicit irredundant generating sets of M11 and M12 of size 5 and 6, respectively. Together these give the full resul...

Two strains of Bacillus pumilus (M11 and M38) and one strain each of Bacillus cereus (M27), Bacillus subtilis (M67), and Enterobacter agglomerans (M14) were identified from the air of Lancashire cotton mills. These strains were tested for cytopathic effects in Vero cells; B pumilus and B cereus strains were also examined for haemolytic activity, lecithinase production, and proteolytic action on...

Diclofenac is a widely used drug that can cause serious hepatotoxicity, which has been linked to metabolism by cytochrome P450s (P450). To investigate the role of oxidative metabolites in diclofenac toxicity, a model for P450-related toxicity was set up in Saccharomyces cerevisiae. We expressed a drug-metabolizing mutant of cytochrome P450 BM3 (BM3 M11) in yeast. Importantly, BM3 M11 yielded si...

A mutant inbred line of Zea mays L. (M11) in which chlorophyll accumulation is particularly sensitive to low temperature is described. Under natural light conditions the chlorophyll content of seedlings is negligible below 17 degrees but is normal at high temperature. Seedlings of M11 can synthesize chloroplast pigments at 16 degrees but at a rate slower than normal. When photo-oxidation is min...

All gammaherpesviruses express homologues of antiapoptotic B-cell lymphoma-2 (BCL-2) to counter the clearance of infected cells by host antiviral defense machineries. To gain insights into the action mechanisms of these viral BCL-2 proteins, we carried out structural and biochemical analyses on the interactions of M11, a viral BCL-2 of murine gamma-herpesvirus 68, with a fragment of proautophag...

BM3, originating from Bacillus megaterium, is a highly active enzyme which has attracted much attention because of its potential applicability as a biocatalyst for oxidative reactions. Previously we developed a drug metabolizing mutant BM3 M11 by a combination of site-directed and random mutagenesis. BM3 M11 contains ten mutations, when compared to wild-type BM3 and is able to produce human-rel...
