Fig. 2. TEX15 is required for TE silencing.
a Representative images of testis sections from adult Tex15+/− and Tex15−/− mice stained with PAS and Haematoxylin (n = 3). Scale bar 50 µm. b, c Representative images of testis sections of (n = 3) adult Tex15+/− and Tex15−/− mice stained for (b) γH2AX showing DNA damage response or (c) TUNEL visualising apoptotic cells. DNA stained with DAPI. Scale bar 50 µm. d, e Adult Tex15+/− and Tex15−/− testis sections (n = 3) stained for (d) LINE1 ORF1p or (e) IAP-GAG protein. DNA stained with DAPI. Scale bar 50 µm. f Heat map from P20 testes and E16.5 gonocytes RNA-seq as indicated showing fold change of the ten most upregulated LINEs and ERVKs in Tex15−/− and Miwi2−/− P20 testis compared to control (n = 3). P < 0.01, Benjamini–Hochberg adjusted two-sided Wald test.
