Genes expression profiles in pigmented regions of the ANG. Expression profiles of selected host genes were analyzed by qPCR, including lipid metabolic process-associated genes: acyl-CoA synthetase long chain family, ACSL (A); UDP-glucuronosyltransferase, UGT (B); acid ceramidase-like, ACL (C), and immune response-associated genes: nitric oxide synthase, NOS (D); transglutaminase 1, TGM1 (E); peptidoglycan recognition protein 2, PGRP2 (F). Differences between pigmented regions were normalized to Ef1a gene expression, with the highest relative value of gene transcript level set to 1. Lowercase letters denote significant differences as determined by one-way ANOVA followed by Tukey’s multiple comparison test (P < 0.05). O, orange; W, white; Y, yellow
