Figure 6. PU-91 regulates inflammation and complement. qRT-PCR analysis showed lower gene expression of inflammation markers such as IFNB1 (p≤0.05, n=4) (A), IL-18 (p≤0.05, n=4) (B) in PU-91-treated AMD cybrids (AMD PU-91) compared to untreated AMD cybrids (AMD UN). However, PU-91 upregulated the complement inhibitor CFH gene (p≤0.05, n=3-4) (C). Data are presented as mean ± SEM and normalized to untreated (UN) AMD cybrids which were assigned a value of 1. Mann-Whitney test was used to measure statistical differences; *p≤0.05.
