Figure 1 (A) Relative mRNA expression of the JMJD1A gene normalized to β-actin in samples with OA (n = 10), SMA (n = 11) and SCOS (n = 10). (B) Total chromatin incorporation of JMJD1A protein normalized to core histone H2A content in OA (n = 5), SMA (n = 7) and SCOS (n = 6) groups. OA = obstructive azoospermia; SCOS = Sertoli cell only syndrome; SMA = round spermatid maturation arrest. Data are shown as mean ± SEM and were analysed using a Kruskal−Wallis test with Dunn's post-hoc test. Asterisks indicate significant differences compared with control (OA), **P < 0.005.

Figure 2 Immunohistochemistry of JMJD1A in human testicular sections. (A, B) Testicular sections of samples with OA (obstructive azoospermia) stained with anti-JMJD1A antibody. (C) Testicular section of a sample with OA without anti-JMJD1A antibody. (D, E) Testicular sections of samples with SMA (round spermatid maturation arrest) stained with anti-JMJD1A antibody. (F) Testicular section of a sample with SMA without anti-JMJD1A antibody. (G, H) Testicular sections of samples with SCOS (Sertoli cell only syndrome) stained with anti-JMJD1A antibody. (I) Testicular section of a sample with SCOS without anti-JMJD1A antibody. CJF = cytoplasmic JMJD1A foci; ES = elongating spermatids; MS = mature spermatids; pSC = pachytene spermatocytes; RS = round spermatids; SC = Sertoli cells; SG = spermatogonia. Scale bar = 20 µm.

Figure 3 (A) Chromatin immunoprecipitation of JMJD1A protein on the promoter regions of TNP1, TNP2, PRM1 and PRM2 genes in patients with OA (n = 12), SMA (n = 12) and SCOS (n = 10). (B) Relative mRNA expression normalized to β-actin of TNP1, TNP2, PRM1 and PRM2 genes in OA (n = 10), SMA (n = 11) and SCOS (n = 10) groups. OA = obstructive azoospermia; SMA = round spermatid maturation arrest; SCOS = Sertoli cell only syndrome. Statistical significance for multiple comparisons was determined by a Kruskal−Wallis test with Dunn's post-hoc test (mean ± SEM). Asterisks indicate significant differences compared with control (OA), **P < 0.005, *P < 0.05. Hash shows significant difference between SMA and SCOS groups, #P < 0.05.
