The neutral cysteine protease bleomycin hydrolase is essential for epidermal integrity and bleomycin resistance.
The papain superfamily member bleomycin hydrolase (Blmh) is a neutral cysteine protease with structural similarity to a 20S proteasome. Bleomycin (BLM), a clinically used glycopeptide anticancer agent, is deaminated in vitro by Blmh. We used gene targeting to generate mice that lack Blmh and demonstrated that Blmh is the sole enzyme required for BLM deamination. Although some Blmh null mice wer...
متن کاملBleomycin initiates apoptosis of lung epithelial cells by ROS but not by Fas/FasL pathway.
Epithelial cells are considered to be a main target of bleomycin-induced lung injury, which leads to fibrosis in vivo. We studied the characteristics of in vitro bleomycin-induced apoptosis in a mouse lung epithelial (MLE) cell line. Bleomycin caused an increase of reactive oxygen species (ROS) resulting in oxidative stress, mitochondrial leakage, and apoptosis. These were associated with eleva...
متن کاملRapid naming is affected by association but not by syntax.
Three experiments are reported that focus on the grammatical and associative relationship between a single word context and a to-be-named target in the SerboCroatian language. Unlike studies using the English language, word class need not be violated in order to obtain grammatical incongruency: all word pairs, therefore, can be semantically plausible. Experiment 1 contrasted naming with lexical...
متن کاملFulminant hyperpyrexia induced by bleomycin.
Mild and self-limiting fever following bleomycin use is common, and a fatal hyperpyrexial response occurs rarely. In previously reported cases, such hyperpyrexia occurred either after the initial administration of the drug or during subsequent therapy following an initial pyrexial response. We describe a fatal hyperpyrexial reaction after bleomycin in a patient with T-cell lymphoma who had had ...
متن کاملPV-1 is negatively regulated by VEGF in the lung of caveolin-1, but not caveolin-2, null mice.
An N-glycosylated 60-kDa PV-1 protein that binds heparin was detected in mouse lung from a single mRNA transcript. In the absence of disulfide bond reduction PV-1 is detected as a dimer or large molecular weight oligomer. In the lung of Cav-1, but not Cav-2, null mice the amount of PV-1 protein is diminished, with no detectable change in mRNA level. PV-1 does not fractionate with caveolae on a ...
