The paper introduces digital-chromosome-banding to analyze meiotic silencing dynamics and identifies sexual dimorphism in meiotic silencing processes.

This study shows folate deficiency during spermatogenesis causes stage-specific metabolic and chromatin changes in the male germline, affecting histone modifications and epigenetic inheritance.

The paper shows that paternal folate deficiency affects meiotic chromatin and epigenomic changes in the male germline, particularly at CGI-associated promoters.

The paper shows Polycomb complexes regulate active chromatin remodeling during ovarian reserve formation and oocyte growth, establishing quiescence and future promoter states through distinct H3K27ac and H3K4me3 dynamics.

This study identifies BAP1 as a key regulator of oocyte epigenome maintenance by restricting Polycomb activity, ensuring proper transcription and female fertility.

The paper identifies newly evolved endogenous retroviruses (ERVs) as drivers of epigenetic priming in non-growing oocytes, enabling follicular activation during oogenesis.

This study shows that SMARCA5 and DMRT1 form a pioneer complex that establishes epigenetic priming necessary for male germline differentiation in response to retinoic acid.

This study shows that non-growing oocytes in mice have pre-established epigenetic marks that prime the epigenome for oocyte maturation and early embryogenesis, challenging the traditional view that these marks are acquired after ovarian reserve exit.

This study shows that KRAB-zinc-finger proteins regulate endogenous retroviruses in the germline, shaping transcriptomes and genome evolution through evolutionary conserved mechanisms.

The paper shows that DNA demethylation during spermatogenesis occurs before nucleosome retention in sperm, contributing to epigenetic reprogramming for embryonic gene regulation.

The paper shows that in mouse male germ cells, promoter chromatin states are shaped by H3K4me3 density and H3K27me3 dynamics, influencing gene expression during development.

This study identifies ATF7IP2 as a critical regulator of H3K9 methylation and meiotic gene regulation in male germline, showing its role in heterochromatin organization and meiotic sex chromosome inactivation.

This study identifies PRC1's role in maintaining adult undifferentiated spermatogonia by directing PRC2-H3K27me3 deposition to prevent differentiation and sustain slow cycling.

This study shows that CTCF-mediated 3D chromatin structure pre-establishes gene expression programs required for spermatogenesis by forming meiosis-specific super-enhancers and regulating chromatin loops.

The paper shows that RNF8 is not required for histone-to-protamine exchange in spermiogenesis, contradicting a previous study.

The paper identifies Polycomb's role in suppressing a female gene regulatory network in Sertoli cells to maintain testicular differentiation.

This study identifies a ZFP541-KCTD19 repressor complex that promotes meiotic prophase exit in spermatogenesis by suppressing transcriptional regulators and chromatin modifiers.

This study identifies endogenous retroviruses as drivers of species-specific germline transcriptomes in mammals, particularly through their role in gene activation and enhancer function in spermatogenesis.

The paper shows that super-enhancer switching drives bursts in germline gene expression during the mitosis-to-meiosis transition in testis.
