Project description:Genome-wide DNA methylation profiling of non-small cell lung cancer (NSCLC) cell line A549 and breast cancer cell line MDA-MB-231 stably expressing hSTELLA and mSTELLA, as well as the HCT116 xenograft tumor tissues from the mice treated by the indicated LNP formulations. The Infinium MethylationEPIC v2.0 array was used to obtain DNA methylation profiles across more than 935,000 CpGs in 15 samples. Samples included 3 stable NSCLC cells and 3 stable breast cancer cells expressing the STELLA orthologs, and 9 xenograft tumors from the mice with the indicated treatments.

DNA Methylome Analysis of Human Cancer Cells with Depleted or Overexpressed STELLA Proteins [Array]

Project description:Genome-wide DNA methylation profiling of the human STELLA (hSTELLA) knockout cell clones derived from TGCT cell lines (BeWo and NCCIT). The DNA methylome profiles are also studied on the CRC cells lines (HCT116 and RKO) stably expressing hSTELLA and mouse STELLA (mSTELLA), as well as on the HCT116 cells treated by LNP-delivered mRNA encoding mSTELLA. The Infinium MethylationEPIC 850k array was used to obtain DNA methylation profiles across more than 850,000 CpGs in 26 samples. Samples included 6 cell clones derived from BeWo cells with hSTELLA knockout or sgRNA control, 5 cell clones derived from NCCIT cells with hSTELLA knockout or sgRNA control, 6 stable CRC cells expressing STELLA orthologs, and 9 LNP-mRNA treated HCT116 cells.

Transcriptome Analysis of Human Cancer Cells with Depleted or Overexpressed STELLA Proteins [RNA-seq]

Project description:UHRF1 maintains DNA methylation by recruiting DNA methyltransferases (DNMT’s) to chromatin. These dynamics are well defined for mouse STELLA (mSTELLA) but poorly characterized for human STELLA (hSTELLA). Herein, we demonstrate that hSTELLA is defective, while mSTELLA is fully proficient in associating with UHRF1 and inhibiting the abnormal DNA methylation and oncogenic functions of UHRF1 in human cancer cells. We illustrate, in structural studies a region of low sequence homology between the above STELLA orthologs, allows mSTELLA but not hSTELLA to bind tightly to the essential histone binding domains of UHRF1, thus mediating their above functional differences. The ortholog-specific binding modes of STELLA proteins with UHRF1 prompt us to explore a rationale for designing UHRF1 inhibitors for cancer therapy. For this, we use a lipid nanoparticle (LNP)-mediated mRNA delivery approach demonstrating the short mSTELLA, but not hSTELLA regions are required to reverse cancer-specific DNA methylation abnormalities and impair CRC tumor growth.

Expression data from cell lines forced expressed PGC7/Stella

Project description:Global DNA hypomethylation and DNA hypermethylation of promoter regionsâincluding tumor suppressor genesâare frequently detected in human cancers. Although many studies have suggested a contribution to carcinogenesis, it is still unclear whether the aberrant DNA hypomethylation observed in tumors is a consequence or a cause of cancer. We found that overexpression of Stella (also known as PGC7, Dppa3), a maternal factor required for the maintenance of DNA methylation in early embryos, induced global DNA hypomethylation and transformation in NIH3T3 cells. This hypomethylation was due to the binding of Stella to Np95 (also known as Uhrf1, ICBP90) and the subsequent impairment of Dnmt1 localization. In addition, enforced expression of Stella enhanced the metastatic ability of B16 melanoma cells through the induction of metastasis-related genes by inducing DNA hypomethylation of their promoter regions. Such DNA hypomethylation itself causes cellular transformation and metastatic ability. These data provide new insight into the function of global DNA hypomethylation in carcinogenesis. We used microarrays to detail the global programme of gene expression by PGC7/Stella overexpression. RNA was extracted from NIH3T3 or B16F10 murine cell lines overexpressed PGC7/Stella and was hybridized on Affymetrix microarrays. We compared gene expression levels between control and PGC7/Stella-overexpressed cells. Microarray analysis was performed in NIH3T3 cells including two independent Stella-expressing NIH3T3 clones and a mixture of Stella-expressing NIH3T3 clones and in B16-F10 cells including three independent Stella-expressing B16-F10 clones.

Stella prevents excessive de novo DNA methylation during mouse oogenesis

Project description:Oocyte acquires developmental competence during its maturation. This stage is accompanied with large-scale alteration in transcription, and series of genome-wide epigenetic reprogramming, including de novo establishment of DNA methylation. However, our understanding of mechanisms regulating this process is limited. To investigate the role of Stella (Dppa3) in de novo methylation during mouse oogenesis, here we measured DNA methylation by RRBS and expression profiles by RNA-seq in PGCs and oocytes at serveral development stages, including genotypes of both Stella (Dppa3) +/- and Stella -/-.

STELLA and MuERV-L activation are essential for early mouse development

Project description:The maternal-to-zygotic transition (MZT) marks the period when the embryonic genome is activated and acquires control of development. Maternally inherited factors play a key role in this critical developmental process, which occurs at the 2-cell stage in mice. Here we investigated the function of the maternally inherited factor STELLA (DPPA3) using single-cell/embryo approaches. This submission concerns itself with transcriptional profiling of wild type and Stella knockout (Stella-/-) oocytes, wild type and Stella maternal/zygotic knockout (StellaM/Z-/-) 1-cell and 2-cell embryos. We show that loss of maternal STELLA results in widespread transcriptional mis-regulation and a partial failure of MZT. Strikingly, activation of the LTR class of transposable elements (TE), and particularly 2-cell specific MuERV-L elements, is significantly impaired in StellaM/Z-/- embryos, which leads to a failure to upregulate selected chimeric transcripts. We propose that STELLA is involved in ensuring activation of TEs that themselves play a key role during early development, in part through regulating embryonic gene expression.
