Professor Douglas R. Tocher has a BSc (1979) and PhD (1982) in Biochemistry from the University of Edinburgh, Scotland. He worked for 16 years for the UK Natural Environment Research Council (NERC) at the Institute of Marine Biochemistry, Aberdeen (1982-1986) and the Unit of Aquatic Biochemistry, University of Stirling (1986-1998). His main research interests during this period were fish lipid and fatty acid metabolism including embryonic and early larval development, and cell culture studies on eicosanoid metabolism, polyunsaturated fatty acid synthesis and neural development. In 1998 he joined the Nutrition Group, Institute of Aquaculture, University of Stirling as senior lecturer and was awarded his personal chair in 2009. His current primary research interests are the molecular biology and genetic basis of regulation of lipid and fatty acid metabolism and nutrition in fish, with particular focus on omega-3 (n-3) long-chain polyunsaturated fatty acids. Professor Tocher has co-authored over 300 scientific publications.
Polyunsaturated fatty-acids in marine and terrestrial food webs. 11th Conference of the European Society for Comparative Physiology and Biochemistry, and 1st Joint Meeting ESCPB - Association Des Physiologistes
European Society for Comparative Physiology and Biochemistry
The work is directed to the research theme "Fish as Food" with the major drivers being sustainabilty of fish farming, while maintenance of health nenefits of fish, and food security. The overarching aim is to develop alternative, more sustainable feeds not dependent upon finite and limited marine resources (fishmeal and fish oil) with a paricular focus on alterantive supplies of omega-3 (n-3) long-chain polyunsaturated fatty acids. Specific aims of current research are focused on the molecular biology of lipids/fatty acids, particularly hepatic microsomal fatty acyl desaturases and polyunsaturated fatty acid elongases and transcription factors and nuclear receptors including peroxisome proliferator activated receptors (PPARs), sterol regulatory element binding proteins (SREBP) and lipid X receptors (LXR) involved in lipid/fatty acid pathway regulation. Application of post-genomic technologies to determine gene expression in various studies of fish lipid metabolism and nutrition including development and utilization of salmon oligonucleotide microarrays and next generation sequencing.
