“…As MTP large subunit is a critical factor for chylomicron and VLDL formation, the tissue specificity of its gene expression during development and in adults could be correlated with the synthesis and secretion of apoB‐containing lipoproteins (Raabe et al,1998,1999; Hussain et al,2003). This lipoprotein synthesis has been demonstrated in mammalian liver, fetal and adult small intestine (Sabesin and Frase,1977; Green and Glickman,1981; Lin et al,1994; Levy and Menard,2000; Levy et al,2001), and heart (Nielsen et al,1998). Similarly, mtp high expression observed in zebrafish anterior intestine and liver could be associated with an intense lipoprotein particles synthesis and transfer in these fish tissues (Iwai,1969; Gauthier and Landis,1972; Noaillac‐Depeyre and Gas,1974,1976; Sire et al,1981; Rombout et al,1984; Wallaert and Babin,1992; André et al,2000).…”
