HIF1A and infection: To monitor BpHIF-1α activation and to explain spatiotemporal expression of BpHIF-1α mRNA in the skin and intestine after infection, we detected common HIF-1α target genes (BpGlut1, BpVegf-a, and BpAldoc), a marker of MO/MΦ in teleosts (BpCSF1R), and a macrophage inflammation marker (BpiNOS) mRNA expression in normal and infected tissues by RT-qPCR.
