ABSTRACT
<p><b>OBJECTIVE</b>To identify the differentially expressed proteins in the liver of Oncomelania snails induced by Eomecon chinanthe sanguinarine.</p><p><b>METHODS</b>Sanguinarine was extracted and purified from the dry powder of Eomecon chinanthe. Oncomelania snails were immersed in 5 mg/L sanguinarine (50 Oncomelania snails per 500 ml) or pure water for 36 h (25°C) and the livers were isolated from live snails. Total liver proteins were extracted and separated by two-dimensional gel electrophoresis. Electrophoretogram was analyzed by Image Master 2D 5.0 software. The differentially expressed proteins between sanguinarine group and pure water group were selected and analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and tandem mass spectrometry sequencing of tryptic peptides.</p><p><b>RESULTS</b>In terms of protein spots, 433 ± 14 and 385 ± 12 were observed in sanguinarine group and in water group respectively. The eleven identified differentially expressed proteins included tropomyosin, hypothetical protein XP_533132, actin 87E, keratin 6A, beta-tubulin, mitochondrial inner membrane protein isoform 4, keratin 2, allatostatin precursor, ENSANGP00000020184, actin-3 and ENSANGP00000013943. Among them, hypothetical protein XP_533132 and ENSANGP00000013943 were down-regulated and the other nine proteins were up-regulated in sanguinarine group.</p><p><b>CONCLUSION</b>Sanguinarine could alter the expression of proteins in livers of Oncomelania snails.</p>
