Uncompleted double-strand repair and synapsis. (A) Spread spermatocytes from Fbxo47+/+ and Fbxo47−/− males were immunostained with anti-SYCP3 and anti-γ-H2AX antibodies. Arrows indicate the sex body; Arrowheads indicate impaired double-strand repair. Scale bars, 10 μm. (B) Spread spermatocytes from Fbxo47+/+ and Fbxo47−/− males were immunostained for synaptonemal complex proteins (SYCP3 and SYCP1). Scale bars, 10 μm. (C) Frequencies of meiotic stages in testes from 8-week-old mice with the indicated genotypes. SYCP3-positive spermatocytes (889 cells were counted) are classified into the following substages: Lep, leptotene (no SYCP1); Zyg, zygotene (partially assembled SYCP1); Pac, pachytene (fully assembled SYCP1); Dip, diplotene (disassembled SYCP1); Met I, metaphase I (no SYCP1 and SYCP3 accumulation at centromeres). Mean values of three independent experiments from three different mice are shown. Error bars, SEM (n = 3).
