Fig 1: (A) The mRNA expression levels of haptoglobin (HP), hemopexin (HPX), and fibrinogen gamma chain (FGG) in the retina of C57BL/6J mice treated by LPS (n = 3) or PBS (n = 3). (B) The protein expression levels of retinal HP, HPX, and FGG in LPS-treated C57BL/6J mice (n = 3) or PBS-treated C57BL/6J control groups (n = 3) were measured by Western blot analysis. GAPDH levels were used as a loading control. Representative Western blot images were shown on the left, and quantification of protein levels (right panel) were normalized to GAPDH protein levels. Data are expressed as the mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001.
