Project description:Cardiomyocyte maturation is the final stage of heart development, and abnormal cardiomyocyte maturation will lead to serious heart diseases. CXXC zinc finger protein 1 (Cfp1) is an important epigenetic factor, which plays an essential role in the development and maturation of multi-lineage cells, while its effect on the maturation of cardiomyocyte remains unclear. This study was performed to explore the potential role of Cfp1 in cardiomyocyte maturation of heart and the underlying mechanisms. Cardiomyocyte-specific Cfp1 knockout (Cfp1-cKO) mice died within 4 weeks of birth. Cardiomyocytes from Cfp1-cKO mice showed an inhibited maturation phenotype in structure, metabolism, contractile function, and cell cycle, accompanied by down-regulation of adult genes and up-regulation of fetal genes. In contrast, cardiomyocyte-specific Cfp1 transgenic (Cfp1-TG) mice and human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) overexpressing Cfp1 showed a more mature phenotype. Mechanistically, deficiency of Cfp1 results in reduced trimethylation on lysine 4 of histone H3 (H3K4me3) modification and formation of ectopic H3K4me3. Moreover, Cfp1 deletion decreased the level of H3K4me3 modification in adult genes and increased the level of H3K4me3 modification in fetal genes. Collectively, Cfp1 modulates the expression of cardiomyocyte maturation related genes by modulating histone H3K4me3 modification, which in turn regulates cardiomyocyte maturation. This study implicates Cfp1 as an important molecule regulating cardiomyocyte maturation, and its dysfunction is strongly associated with cardiac disease.

Project description:CXXC finger protein 1 (Cfp1) is a DNA-binding component of the SETD1 methyltransferase complex, targets SETD1A/B to most CpG islands (CpGI), and mediates the generation of H3K4me3. Deficiency of CFP1 in mice leads to pre-implantation lethality. Previous data suggest an indispensable role of CFP1 in germ cell development and meiosis. However, it remains unclear if CFP1-mediated H3K4 trimethylation is also required for the earliest stages of meiosis in both male and female germ cells. Here, we revealed that Cxxc1 deletion caused a decrease of H3K4me3 levels in spermatocytes after the zygotene stage, impaired double strand breaks (DSBs) repairing, and crossover formation in meiotic prophase. As the results, Cxxc1-deleted spermatocytes failed to complete meiosis and were arrested at the meiosis II. ChIP-seq results revealed that H3K4me3 globally descreased at transcriptional start sites in Cxxc1-null spermatocytes at the leptotene/zygotene and pathytene stages.RNA-seq at different stages revealed an earlier expression of genes within the spermatogenesis pathway in Cxxc1-null spermatocytes. These results indicated that CFP1 is required for H3K4me3 accumulation at the gene promoters of male germ cells and play a key role in regulating programed gene expression that is essential for spermatogenesis.

Project description:Spermatogenesis is a complex process involving meiosis in spermatocytes and dynamic epigenetic changes that ensure the inheritance of genetic traits. CXXC finger protein 1 (Cfp1), a component of the SETD1 methyltransferase complex, has a binding domain specific for unmethylated CpG sites. Previous studies have implicated Cfp1 in the epigenetic changes required for meiosis in spermatocytes, and its loss of function has been shown to result in male sterility. In this study, we aimed to gain a comprehensive understanding of Cfp1 function in spermatocytes by examining its genome-wide binding profile and the resulting changes in DNA methylation and H3K4me3, a histone modification associated with active gene transcription. We isolated Cfp1-depleted spermatocytes and performed H3K4me3 ChIP-seq and reduced-representation bisulfite sequencing (RRBS) analyses. By integrating these multi-omics datasets with Cfp1 ChIP-seq analysis, we identified genes directly regulated by Cfp1 and characterised the epigenetic changes associated with its regulation. Our analysis shows that Cfp1 not only directly affects the regulation of genes essential for meiosis, but also has a significant impact on the overall regulation of gene expression. The knowledge gained from studying the regulatory mechanisms of Cfp1 in spermatocytes provides valuable information about the reproductive process and contributes to our understanding of the underlying causes of infertility.

Project description:Meiosis occurs specifically in germ cells to produce sperm and oocytes that are competent for sexual reproduction. Multiple factors are required for successful meiotic entry, progression, and termination. Trimethylation of histone H3 on lysine 4 (H3K4me3), a mark of active transcription, has been implicated in spermatogenesis by forming double strand breaks (DSBs). The role of H3K4me in transcriptional regulation during meiosis however, remains poorly understood. Here, we reveal that mouse CXXC finger protein 1 (Cfp1), a component of H3K4me methyltransferases Setd1a/b, is dynamically expressed in differentiating male germ cells and safeguards meiosis by controlling gene expression. Depletion of Cfp1 in male germ cells resulted in infertility with reduced H3K4me3, spermatogenic arrest, and repression of essential germ cell development and meiosis genes. Importantly, ChIP-Seq analysis revealed that Cfp1 is mainly enriched at transcriptional start sites to promote gene expression and H3K4me2/3 levels at pachytene stage. The most highly enriched genes were associated with meiosis and homologous recombination during differentiation of spermatocytes to round spermatids. Additionally, missense mutations of human CFP1 were prevalent in patients with nonobstructive azoospermia. Therefore, our study establishes a mechanistic link between CFP1-mediated transcriptional control and meiotic progression, and provides unprecedented genetic basis for understanding human sterility.

Project description:Chromatin modifications and the promoter associated epigenome are thought to be important for the regulation of gene expression. However, the mechanisms by which chromatin modifying complexes are targeted to the appropriate gene promoters in vertebrates and how they influence gene expression have remained poorly defined. Here, using a combination of live cell imaging and functional genomics, we discover that the vertebrate SET1 complex is targeted to actively transcribed target gene promoters through CFP1 which engages in a unique form of multivalent chromatin reading that involves recognition of non-methylated DNA and histone H3 lysine 4 trimethylation (H3K4me3). CFP1 defines SET1 complex occupancy on chromatin and its multivalent interactions are required for the SET1 complex to place H3K4me3. In the absence of CFP1, gene expression is perturbed suggesting that the normal targeting and function of SET1 complex is central to creating an appropriately functioning vertebrate promoter associated epigenome.

Project description:The CFP1/CXXC protein targets SET1/COMPASS complexes to non-methylated CpG rich promoter regions to implement tri-methylation of histone H3 Ly4 (H3K4me3). Although H3K4me3 is widely associated with gene expression, the effects of CFP1 loss depend on chromatin context. Little is known about how CFP1 binding is coordinated with other chromatin factors. Using a proteomics approach, we establish a link between C. elegans CFP1 and a small Rpd3/Sin3 histone deacetylase (HDAC) complex (Sin3S). Mutants of CFP-1, SIN-3, and the catalytic subunit SET-2/SET1 have similar phenotypes and misregulate the expression of common genes. CFP-1 directly interacts with SIN-3 through a region including the conserved PAH1 domain, and contributes to recruitment of SIN-3 and the Sin3S subunit HDA-1 to H3K4me3 enriched promoters. Our results reveal a novel role for CFP-1 in mediating interaction between SET1/COMPASS and a Sin3 HDAC small complex at promoters, with implications for the coordinate regulation of gene expression by chromatin- associated complexes with distinct activities.

Project description:Histone H3 lysine 4 trimethylation (H3K4me3) is a canonical chromatin modification associated with active gene transcription, playing a pivotal role in regulating various cellular functions. Components of the H3K4me3 methyltransferase complex, known as the proteins associated with SET1 (COMPASS), have been implicated in exerting cancer-protective or cancer-inhibitory effects through inducive H3K4me3 modification. However, the role of the indispensable non-catalytic component of COMPASS CXXC-type zinc finger protein 1 (CFP1) in malignant progression remains unclear. We have unveiled that CFP1 promote lung adenocarcinoma (LUAD) cell proliferation, migration, and invasion while impairing cell apoptosis through in vitro and in vivo models. In addition, high CFP1 expression was identified as emerged as an adverse prognostic indicator across multiple public and in-house LUAD datasets. Notably, CFP1 deficiency led to dual effects on cancer cell transcriptome including extensive inactivation of cancer-promoting as well as activation of cancer repressors. Combining this with the chromatin immunoprecipitation sequencing (ChIP-seq) analysis, we showed that CFP1 ablation reshaped the genomic H3K4me3 distribution signature, with prominent effects on TGF-β and WNT signaling pathways. Collectively, our study proposes that CFP1 mediates tumorigenesis by genomic histone methylation reprogramming, offering insights for future investigations into epigenetic modifications in cancer progression and potential therapeutic advancements.
