Expression of candidate genes analyzed by real-time PCR. Expression profile of p21 (Cdkn1a), Pon1 (paraoxonase 1) Ttr (transthyretin) and Adm (adrenomedullin) immediately after hypoxic exposure (0 h), or after a period of 2 h, 4 h or 16 h of reoxygenation as determined by real-time PCR. Fold-changes are expressed relative to normoxic controls of respective time points, which were set to one. n = 5 for each treatment and time point. White bars: samples of normoxic retinas, grey bars: samples of hypoxic preconditioned retinas; *** p ≥ 0.001, ** p ≥ 0.01, * p ≥ 0.05).
