The potential to form intermediate filaments of a 54 X 10(3) molecular weight (Mr) polypeptide derived from vimentin by cleavage by the intermediate filament-specific, Ca2+-activated proteinase was investigated. Under physiological conditions of assembly, the breakdown product did not form intermediate filaments. Electron microscopy revealed short, rod-like structures similar to those described...
The primary aim was to study the relationship between individual serum levels of 25-hydroxyvitamin D and 4b-hydroxycholesterol, which is an endogenous biomarker of the drug-metabolizing CYP3A enzymes. In addition, the relationship between this biomarker and inflammation, measured as C-reactive protein (CRP), was investigated. Serum samples were used from a recently performed clinical trial in p...
The effect of phorbol 12-myristate 13-acetate on the phosphorylation of the ras p21 protein was studied by metabolically labeling cultured cells with [32P]orthophosphate and using a monoclonal antibody to immunoprecipitate the protein. Phorbol 12-myristate 13-acetate (100 nM) induced phosphorylation of cKi-ras p21 in a mouse adrenocortical cell line (Yl) expressing high levels of cKi-ras with e...

The transcription factor C/EBPβ plays a key role in monocytic differentiation and inflammation. Its small isoform LIP is associated with proliferation at early premonocytic developmental stages and regulated via mTOR-dependent signalling. During later stages of (pre)monocytic differentiation there is a considerable increase in the large C/EBPβ isoforms LAP*/LAP which inhibit proliferation thus ...
A 130,000 Mr protein was isolated from human platelets by sequential DEAE-Sephacel and Sepharose Cl-4B chromatography. Low shear viscometric measurements showed that the enriched protein after DEAE-Sephacel chromatography inhibited actin polymerization. This effect was somewhat greater in the presence of EGTA than in the presence of calcium. Further purification by Sepharose Cl-4B chromatograph...
Two protein phosphatases (enzymes I and II) were extensively purified from wheat embryo by a procedure involving chromatography on DEAE-cellulose, phenyl-Sepharose CL-4B, DEAE-Sephacel and Ultrogel AcA 44. Preparations of enzyme I (Mr 197,000) are heterogeneous. Preparations of enzyme II (Mr 35,000) contain only one major polypeptide (Mr 17,500), which exactly co-purifies with protein phosphata...
