Figure 2. Lack of LIF prevents activation
of STAT3 signaling. Relative levels of Lif, Clc, Stat3,
and Socs3 mRNAs (as indicated) were analyzed by real-time PCR
in retinas of Lif+/– and Lif–/–
mice before (controls) or at 12 h after exposure to 15,000 lx of
white light for 2 h. RNA levels were expressed relative to levels in Lif+/–
controls, which were set to 1. β-actin served as reference.
Shown are means±SD of n=3.
