Abstract

Protein diversity of the high molecular weight fraction (molecular mass > 500 daltons) of salivary grand secretion of the medicinal leech Hirudo medicinalis has been demonstrated using methods of proteomic analysis. One-dimensional (1D) electrophoresis revealed the presence of more than 60 bands corresponding to molecular masses ranging from 11 to 483 kD. 2D-electrophoresis revealed more than 100 specific protein spots differing in molecular masses and pI values. SELDI-mass spectrometry analysis using the ProteinChip. System based on chromatography surfaces of strong anion or weak cation exchanger detected 45 individual compounds of molecular masses ranged from 1.964 to 66.5 kD. Comparison of SELDI-MS data with protein databases revealed eight known proteins from the medicinal leech. Other masses detected by proteomic analytical methods may be related to both modifications of known proteins and unknown biologically active components of leech saliva secretion.

Pioneering 2D-PAGE and mass-spec proteomic profiling of medicinal leech salivary gland secretion. First systematic catalog of salivary protein components.

Por qué esto importa para la hirudoterapia

This study demonstrated protein diversity in the high molecular weight fraction of salivary gland secretion from Hirudo medicinalis using multiple proteomic methods. One-dimensional electrophoresis revealed more than 60 bands, 2D-electrophoresis revealed over 100 specific protein spots, and SELDI-mass spectrometry detected 45 individual compounds. Comparison with protein databases identified eight known proteins from the medicinal leech, while the abstract notes other detected masses may be related to modifications of known proteins or unknown biologically active components of leech saliva secretion. The relevance to the leech secretome is a descriptive biochemical inventory of protein composition. The limitation is that the study is purely descriptive, and the biological activity of the unidentified components is not characterized.
