  1. Regulation of n-3 PUFA biosynthesis in proliferating and differentiated PC12 pheochromocytoma cells

    Msika, OraLondon Metropolitan University2012

    Regulation of polyunsaturated fatty acid (PUFA) biosynthesis in proliferating and NGF-differentiated PC12 pheochromocytoma cells deficient in n-3 docosahexaenoic acid (DHA, 22:6n- 3) was studied. A dose- and time dependent increase in eicosapentaenoic acid (EPA, 20:5n-3), docosapentaenoic acid …
