Knockdown of slc7a14 led to increased apoptosis in the zebrafish retina. TUNEL assay was used to detect apoptosis in larval retinas at 3 and 5 dpf. (A,B) Slc7a14 knockdown resulted in significant increase of TUNEL + cells in the retina including GCL, INL, ONL and RPE at 3 dpf (A) and 5 dpf (B). Scale bars = 50 μm. (C,D) Statistical results for the numbers of TUNEL positive cell at 3 dpf (n = 6 for each group) and at 5 dpf (n = 3 for each group). Bar plots were shown as the mean ± s.e.m. T-test was performed between the two groups. ∗P < 0.05, ∗∗∗P < 0.001.
