English: Relative ApoD mRNA and protein expression in tissues of different species. ApoD expression in the figure is an average value from the literature. ApoD expression in a tissue is expressed as a percentage of the strongest ApoD tissue expression for that species. Tissue expression between different species should not be compared as they are only relative to their own species. Tissues in which ApoD was detected but not quantified are noted in yellow. Expression data were obtained from multiple sources: Human: (Uhlen et al. 2015) data available at https://www.proteinatlas.org/ENSG00000189058-APOD/tissue, (Fishilevich et al. 2016; Ben-Ari Fuchs et al. 2016) data available at https://www.genecards.org/cgi-bin/carddisp.pl?gene=APOD, (Séguin et al.,1995; Drayna et al. 1986); Rhesus (Smith et alo., 1990); Rabbit (Provost et al. 1990); Mouse (Séguin et al., 1995; Do Carmo et al. 2009a; Li et al. 2016; Cofer and Ross 1996); Rat (Séguin, Desforges, and Rassart 1995; Boyles et al. 1990); Guinea pig (Provost et al. 1995); Chicken (Ganfornina et al. 2005).
