KAT5 and cyst: First, excess Zfh-1-expressing cells could be detected in 74% of Tj>Tip60 RNAi (N = 70, Fig 7A’) and 77% of Tj>Tip60E431Q (N = 52, Fig 7B’) testes, leading to the co-expression of Zfh-1 and Eya in the cyst cells of both Tj>Tip60 RNAi (yellow arrows, Fig 7A’–7A”’) and Tj>Tip60E431Q (yellow arrows, Fig 7B’–7B”‘) testes.
