Abstract
The identification of cell-type-specific 3D chromatin interactions between regulatory elements can help to decipher gene regulation and to interpret the function of disease-associated non-coding variants. However, current chromosome conformation capture (3C) technologies are unable to resolve interactions at this resolution when only small numbers of cells are available as input. We therefore present ChromaFold, a deep learning model that predicts 3D contact maps and regulatory interactions from single-cell ATAC sequencing (scATAC-seq) data alone. ChromaFold uses pseudobulk chromatin accessibility, co-accessibility profiles across metacells, and predicted CTCF motif tracks as input features and employs a lightweight architecture to enable training on standard GPUs. Once trained on paired scATAC-seq and Hi-C data in human cell lines and tissues, ChromaFold can accurately predict both the 3D contact map and peak-level interactions across diverse human and mouse test cell types. In benchmarking against a recent deep learning method that uses bulk ATAC-seq, DNA sequence, and CTCF ChIP-seq to make cell-type-specific predictions, ChromaFold yields superior prediction performance when including CTCF ChIP-seq data as an input and comparable performance without. Finally, fine-tuning ChromaFold on paired scATAC-seq and Hi-C in a complex tissue enables deconvolution of chromatin interactions across cell subpopulations. ChromaFold thus achieves state-of-the-art prediction of 3D contact maps and regulatory interactions using scATAC-seq alone as input data, enabling accurate inference of cell-type-specific interactions in settings where 3C-based assays are infeasible.

Abstract
Abstract
Metastasis is the leading cause of cancer-related death among women with breast cancer. Chromosomal instability (CIN) has emerged as a hallmark of triple-negative breast cancer (TNBC) as it has recently been shown to promote metastasis. However, the underlying molecular mechanisms by which CIN drives metastasis are not completely understood. We have identified a discrete population of highly metastatic SOX2/OCT4+ cells expressing elevated levels of epigenetic regulator EZH2 associated with increased CIN in both human and mouse TNBC. EZH2 histone methyl transferase (HMT) is the catalytic subunit of the Polycomb repressive complex 2 (PRC2), represses target genes through trimethylation of Histone 3 at lysine 27 (H3K27me3). Importantly, genetic and pharmacologic inhibition of EZH2 lead to reduction of CIN and impaired metastasis. These findings led to the hypothesis that EZH2-mediated CIN constitutes a novel mechanism of metastasis regulation. To directly demonstrate epigenetic regulation of CIN, we used genome wide-Cleavage Under Targets and Release Using Nuclease (CUT&RUN) in parallel with RNA-seq. Gene set enrichment of EZH2-repressed target genes directly implicated the spindle formation pathway network. The central core of this network comprised of tankyrase (TNKS), a multifunctional poly (ADP-ribose) polymerase (PARP) previously implicated in DNA repair, telomere function and centrosome maturation. ChIP-PCR confirmed that EZH2 directly binds to the TNKS promoter, and CRISPR knockout of TNKS abrogated the ability of EZH2 inhibition in suppressing CIN, consistent with pharmacological inhibition of TNKS. More specifically, dysregulation of TNKS by EZH2 in OCT4/SOX2+ cells lead to increased numbers of centrosomes and multipolar mitosis. To directly demonstrate the role of aberrant H3K27me3 in regulating chromosomal segregation during mitosis, we used dCas9-EZH2 or dCas9-EZH2 catalytically dead mutant together with chromosome-specific CRISPR guides to ectopically enhance H3K27 trimethylation at the pericentromeric region of specific chromosomes. Ectopic deposition of EZH2 at pericentromeric regions lead to increased CIN.
Conceptually, our work provides an unappreciated link between epigenetic regulation and CIN which have been hitherto studied in isolation. From a clinical perspective, demonstrating epigenetic regulation of CIN has opened the possibility for the development of first CIN suppressive therapeutic strategies targeting TNBC metastasis.

Abstract
A third of patients with diffuse large B-cell lymphoma (DLBCL) present with extranodal dissemination, which is associated with inferior clinical outcomes. MYD88L265P is a hallmark extranodal DLBCL mutation that supports lymphoma proliferation. Yet extranodal lymphomagenesis and the role of MYD88L265P in transformation remain mostly unknown. Here, we show that B cells expressing Myd88L252P (MYD88L265P murine equivalent) activate, proliferate, and differentiate with minimal T-cell costimulation. Additionally, Myd88L252P skewed B cells toward memory fate. Unexpectedly, the transcriptional and phenotypic profiles of B cells expressing Myd88L252P, or other extranodal lymphoma founder mutations, resembled those of CD11c+T-BET+ aged/autoimmune memory B cells (AiBC). AiBC-like cells progressively accumulated in animals prone to develop lymphomas, and ablation of T-BET, the AiBC master regulator, stripped mouse and human mutant B cells of their competitive fitness. By identifying a phenotypically defined prospective lymphoma precursor population and its dependencies, our findings pave the way for the early detection of premalignant states and targeted prophylactic interventions in high-risk patients. SIGNIFICANCE Extranodal lymphomas feature a very poor prognosis. The identification of phenotypically distinguishable prospective precursor cells represents a milestone in the pursuit of earlier diagnosis, patient stratification, and prophylactic interventions. Conceptually, we found that extranodal lymphomas and autoimmune disorders harness overlapping pathogenic trajectories, suggesting these B-cell disorders develop and evolve within a spectrum.

Abstract
Diffuse large B cell lymphoma (DLBCL) is a markedly phenotypically heterogenous disease, frequently assessed using bulk genomic techniques that blur the intrinsic heterogeneity of each tumor. In this issue of Cancer Cell, Steen et al. have utilized a computational framework called EcoTyper to skillfully dissect bulk transcriptomic tumor profiles into different cell type components in an unsupervised manner.

Abstract
The normal androgen receptor (AR) cistrome and transcriptional program are fundamentally altered in prostate cancer (PCa). Here, we profile the chromatin landscape and AR-directed transcriptional program in normal prostate cells and show the impact of SPOP mutations, an early event in prostate tumorigenesis. In genetically normal mouse prostate organoids, SPOP mutation results in accessibility and AR binding patterns similar to that of human PCa. Consistent with dependence on AR signaling, castration of SPOP mutant mouse models results in the loss of neoplastic phenotypes, and human SPOP mutant PCa shows a favorable response to AR-targeted therapies. Together, these data validate mouse prostate organoids as a robust model for studying epigenomic and transcriptional alterations in normal prostate, provide valuable datasets for further studies, and show that a single genomic alteration may be sufficient to reprogram the chromatin of normal prostate cells toward oncogenic phenotypes, with potential therapeutic implications for AR-targeting therapies.

Abstract
During the germinal center (GC) reaction, B cells undergo extensive redistribution of cohesin complex and three-dimensional reorganization of their genomes. Yet, the significance of cohesin and architectural programming in the humoral immune response is unknown. Herein we report that homozygous deletion of Smc3, encoding the cohesin ATPase subunit, abrogated GC formation, while, in marked contrast, Smc3 haploinsufficiency resulted in GC hyperplasia, skewing of GC polarity and impaired plasma cell (PC) differentiation. Genome-wide chromosomal conformation and transcriptional profiling revealed defects in GC B cell terminal differentiation programs controlled by the lymphoma epigenetic tumor suppressors Tet2 and Kmt2d and failure of Smc3-haploinsufficient GC B cells to switch from B cell- to PC-defining transcription factors. Smc3 haploinsufficiency preferentially impaired the connectivity of enhancer elements controlling various lymphoma tumor suppressor genes, and, accordingly, Smc3 haploinsufficiency accelerated lymphomagenesis in mice with constitutive Bcl6 expression. Collectively, our data indicate a dose-dependent function for cohesin in humoral immunity to facilitate the B cell to PC phenotypic switch while restricting malignant transformation.

Abstract
Metastasis is the leading cause of cancer mortality. Chromatin remodeling provides the foundation for the cellular reprogramming necessary to drive metastasis. However, little is known about the nature of this remodeling and its regulation. Here, we show that metastasis-inducing pathways regulate histone chaperones to reduce canonical histone incorporation into chromatin, triggering deposition of H3.3 variant at the promoters of poor-prognosis genes and metastasis-inducing transcription factors. This specific incorporation of H3.3 into chromatin is both necessary and sufficient for the induction of aggressive traits that allow for metastasis formation. Together, our data clearly show incorporation of histone variant H3.3 into chromatin as a major regulator of cell fate during tumorigenesis, and histone chaperones as valuable therapeutic targets for invasive carcinomas.
