Fig. 4. Expression of neuroglobin (Ngb) mRNA in zebrafish eye and brain. Zebrafish
were kept for 24 h at normoxia (white columns) or
PO2=
4.1 kPa (black columns). Ngb mRNA levels from eye
and brain were quantified separately by real-time PCR (N=4). The
units of the y-axis are arbitrary. *P<0.05
(t-test).
