Key result
Fish brains exhibited higher GD3-, GT3-, GD1a-, and GT1a-synthase activities compared to rat brains, correlating with an enrichment of c-series gangliosides in fish.
Species-specific expression of gangliosides in brain tissues may be regulated at the level of sialyltransferase activities.
No takes yet. Share an insight, caveat, or question.
Species differences in brain ganglioside synthesis warrant caution extrapolating rodent data; leaves open sialyltransferase roles in vertebrate neurochemistry.
Freischütz et al. (1994) studied this question. Cichlid fish brain membranes vs. Sprague-Dawley rat brain membranes was evaluated on Sialyltransferase activities and ganglioside compositions. Fish brains exhibited higher GD3-, GT3-, GD1a-, and GT1a-synthase activities compared to rat brains, correlating with an enrichment of c-series gangliosides in fish.
