Exposure to hyperbaric pressure alters ganglioside expression in rat liver following partial hepatectomy
Remnant liver after partial hepatectomy (PH) demands an increased amount of oxygen to restore hepatic energy. Modulation of the ganglioside content of hepatocyte plasma membrane could provide a mean for upregulating cellular responsiveness to a variety of factors. Rat liver gangliosides were analysed by high performance thin layer chromatography (HPTLC) followed with immunostaining 54 h after PH. Non-operated and three different groups of operated rats were studied according to the hausing conditions before or after operation: recovering under normal ambient conditions after operation (1), treating with hyperbaric pressure before operation and recovering under normal ambient conditions (2 or preHB), and recovering under hyperbaric pressure after operation (3 or postHB). Liver of preHB group showed the highest expression of ganglioside GD1a, a marker of a peculiar transition phase of liver regeneration. Same animals showed enhanced expression of the several gangliosides: GM2, GM1a, GD1b, GT1b, Gal-NAcGM1b, nLc4, nLc6 and nLc8. Since galactosyl- and N-acetylgalactosaminyltransferase catalyse final step of synthesis of GM2, GM1a, GD1b, Gal-NAcGM1b, nLc4, nLc6, and nLc8, our results point at possible role of galactosyl- and N-acetylgalactosaminyltransferase in regulation of the liver growth after PH.
