Genetic analyses in mice identifies Rlim in the spermatogenic cell lineage as a regulator of cytoplasmic reduction during spermiogenesis.

The H3K36 and H3K27 histone methyltransferases MES-4 and PRC2 protect survival of the nascent germline in Caenorhabditis elegans by repressing expression of X-linked genes, including the key transcription factor LIN-15B.

Human cell lines regress to become ‘de-sexualized’ by reconfiguring to a 2:3 X/A ratio of high fitness, thus shedding light on the evolution of mammalian sex chromosomes.

Activity-dependent genetic labeling during behavioral learning shows Fragile-X syndrome model mice exhibit impaired hippocampal engram reactivation, and that enriched environment experience improves fear memory retrieval by enhancing engram reactivation efficacy.

The rapidly evolving X-linked MIR-506 family miRNAs function to enhance sperm competitiveness and male reproductive fitness in mice.

Genomic imprinting in the bryophyte Marchantia polymorpha by Polycomb results in maternal dominance of embryonic gene expression.

A chromosome-wide mechanism balances X-linked gene expression between the sexes in C. elegans, but no similar chromosome-wide mechanism balances gene expression between X chromosomes and autosomes.

Following fertilization, the pioneering transcription factors GAGA factor (GAF) and Zelda are independently required to reprogram the zygotic genome of Drosophila and activate the first wave of gene expression.

Boundary:boundary pairing interactions drive TAD formation in Drosophila.

rDNA copy number is shown to dynamically change during aging and through generations, and is actively maintained in male germline of Drosophila.
