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.

Resumen

2D-electrophoresis and SELDI-MS revealed >100 specific spots and 45 individual compounds (1.964-66.5 kD) in Hirudo medicinalis salivary gland secretion, with 8 known leech proteins matched.

Por qué esto importa para la hirudoterapia

This study characterizes the protein diversity of the high molecular weight fraction of salivary gland secretions from the medicinal leech Hirudo medicinalis using one-dimensional and two-dimensional electrophoresis and SELDI-mass spectrometry. Researchers detected more than 60 bands by 1D electrophoresis, over 100 specific protein spots by 2D electrophoresis, and 45 individual compounds by SELDI-MS, with database comparisons identifying eight known leech proteins and additional masses potentially representing modifications of known proteins or unknown biologically active components. This is directly relevant to ASH's domain as a molecular profiling study of leech salivary secretions. However, the study reports protein identification and characterization only; no bioactivity assays, therapeutic applications, or clinical outcomes are described in the abstract.
