Abstract
SET (SuVar3-9, Enhancer of Zeste, Trithorax) domain bifurcated histone lysine methyltransferase 1, setdb1, is the predominant histone lysine methyltransferase catalyzing H3K9me3. Prior studies have illustrated that setdb1 and H3K9me3 critically regulate sex differentiation and gametogenesis. However, the molecular details by which setdb1 is involved in these processes in fish have been poorly reported. Here, we cloned and characterized the setdb1 ORF (open reading frame) sequence from Chinese tongue sole (Cynoglossus semilaevis). The setdb1 ORF sequence was 3,669 bp, encoding a 1,222-amino-acid protein. Phylogenetic analysis showed that setdb1 was structurally conserved. qRT-PCR revealed that setdb1 had a high expression level in the testes at 12 mpf (months post fertilization). Single-cell RNA-seq data at 24 mpf indicated that setdb1 was generally expressed in spermatogenic cells at each stage except for sperm and was centrally expressed in oogonia. H3K9me3 modification was observed in gonads with the immunofluorescence technique. Furthermore, the overexpression experiment suggested that sox5 was a candidate target of setdb1. sox5 was abundantly expressed in male and pseudomale gonads at 24 mpf. Single-cell RNA-seq data showed that sox5 was mainly expressed in spermatogonia and its expression gradually declined with differentiation. Taken together, our findings imply that setdb1 regulates sox5 transcription in gonads, which provides molecular clues into histone modification-mediated orchestration of sex differentiation and gametogenesis.

Abstract
The association of genomic loci to the nuclear periphery is proposed to facilitate cell-type specific gene repression and influence cell fate decisions. However, the interplay between gene position and expression remains incompletely understood, in part because the proteins that position genomic loci at the nuclear periphery remain unidentified. Here, we used an Oligopaint-based HiDRO screen targeting ~1000 genes to discover novel regulators of nuclear architecture in Drosophila cells. We identified the heterochromatin-associated protein, Stonewall (Stwl), as a factor promoting perinuclear chromatin positioning. In female germline stem cells (GSCs), Stwl binds and positions chromatin loci, including GSC differentiation genes, at the nuclear periphery. Strikingly, Stwl-dependent perinuclear positioning is associated with transcriptional repression, highlighting a likely mechanism for Stwl's known role in GSC maintenance and ovary homeostasis. Thus, our study identifies perinuclear anchors in Drosophila and demonstrates the importance of gene repression at the nuclear periphery for cell fate.

Abstract
Genome organization can regulate gene expression and promote cell fate transitions. The differentiation of germline stem cells (GSCs) to oocytes in Drosophila involves changes in genome organization mediated by heterochromatin and the nuclear pore complex (NPC). Heterochromatin represses germ-cell genes during differentiation and NPCs anchor these silenced genes to the nuclear periphery, maintaining silencing to allow for oocyte development. Surprisingly, we find that genome organization also contributes to NPC formation, mediated by the transcription factor Stonewall (Stwl). As GSCs differentiate, Stwl accumulates at boundaries between silenced and active gene compartments. Stwl at these boundaries plays a pivotal role in transitioning germ-cell genes into a silenced state and activating a group of oocyte genes and Nucleoporins (Nups). The upregulation of these Nups during differentiation is crucial for NPC formation and further genome organization. Thus, crosstalk between genome architecture and NPCs is essential for successful cell fate transitions.
