. Relationship between PIWIL4-Mediated H3K4me2 Demethylation and piRNA-Dependent DNA Methylation. Cell Rep. 2018;25:350-356 pubmed publisher
..In addition, PIWIL4, which binds the H3K4 demethylases KDM1A and KDM5B, is required for removing H3K4me2 marks. These data show that PIWIL4 plays important roles in histone modification and piRNA-dependent DNA methylation. ..

. Comprehensive DNA Methylation Analysis of Retrotransposons in Male Germ Cells. Cell Rep. 2015;12:1541-7 pubmed publisher
..These observations raise the possibility of piRNA-dependent DNA methylation without Miwi2. Therefore, it appears that the molecular mechanisms of the gene silencing of retrotransposons are more complicated than previously thought. ..
