Identification of protein components of the transformation system in the cell line of immortalized human keratinocytes HaCaT exposed to surfactants.

Using the method of shotgun mass spectrometry, we have evaluated changes in the proteomic profile of HaCat cells in response to the treatment with sodium dodecyl sulfate (anionic surfactant) and Triton-X100 (non-ionic surfactant) in two concentrations (12.5 µg/ml and 25.0 µg/ml).

[Comparative Analysis of the Performance of Mascot and IdentiPy Algorithms on a Benchmark Dataset Obtained by Tandem Mass Spectrometry Analysis of Testicular Biopsies].

Proteome profiling of human testicular biopsies was performed using tandem mass spectrometry with electrospray ionization. Protein identification results were compared for the Mascot commercial search engine, the SearchGUI noncommercial package, and their analog IdentiProt based on the open-source IdentiPy algorithm (http://hg.theorchromo.

Analysis of Blood Plasma Protein Composition in Patients with Cerebral Ischemia.

Blood plasma proteome in patients with cerebral ischemia and healthy individuals was studied using comparative proteomic analysis based on tandem HPLC-MS/MS. Mass spectra were analysed in an automated mode using Progenesis LS-MS software and 256 proteins were identified. Significant quantitative differences were revealed for 20 proteins.

Effects of fullerene C60 on proteomic profile of Danio rerio fish embryos.

The effects of phosphatidylcholine-based phospholipid nanoparticles containing fullerene C60 on Danio rerio fish embryos were studied. Exposure of the embryos with the nanoparticles for 48 h did not lead to appreciable changes in the number of protein bands in SDS-PAGE in comparison with the control (exposure in medium with phosphatidylcholine). Mass spectrometric identification of proteins showed differences in the proteomic profiles of the samples.
