Project description:We built novel tri-cultures of HGSOC cells with human primary omental adipocytes and fibroblasts which replicated tissue remodelling and matrisome production observed in biopsies. RNAseq analysis showed that tri-cultures reproduced the prognostic matrisome signature.
Project description:Comparison of CheZ interactors’ ratio of two replicate experiments using five different methods, i.e., Affinity-Purification, Tri-functional affinity probe Sulfo-SBED and proximity labeling methods BioID, SPIDER, PUP-IT
Project description:We measured gene expression in single-cell RNA sequencing samples from patients with high-grade serous ovarian cancer (HGSOC), for a study on improving HGSOC subtype definition by taking into account varying cell type proportions within tumors.

Project description:Synthesis and accumulation of seed storage proteins (SSPs) is an important aspect of the seed maturation program. Genes encoding SSPs are specifically and highly expressed in the seed during maturation. However, the mechanisms that repress the expression of these genes in leaf tissue are not well understood. To gain insight into the repression mechanisms, we have performed a transgenic screening for mutants that express SSPs in leaves. Here we show that mutations of BRAHMA (BRM), a SNF2 chromatin remodelling ATPase, cause the ectopic expression of a subset of SSPs and other embryogenesis related genes in leaf tissue. Consistent with the notion that such SNF2-like ATPases form protein complexes in vivo, we observed similar phenotypes for mutations of AtSWI3C, a BRM interacting partner, and BSH, a SNF5 homolog and essential SWI/SNF subunit. Further, we present chromatin immunoprecipitation evidence that BRM is recruited to the promoters of a number of embryogenesis genes including the 2S genes, which are expressed/elevated in brm leaves. Consistent with its role in nucleosome remodelling, BRM appears to control the chromatin structure of the At2S2 promoter. These results show that a BRM-containing chromatin remodelling ATPase complex is involved in the direct repression of SSPs in leaf tissue. A matrix comprising the signal intensity value of each gene per replicate hybridization and the averaged data of each gene generated from three replicate hybridizations of the wild type and mutant samples, respectively, is linked below as a supplementary file.
Project description:Tumor cells were isolated from solid tumors or ascites from HGSOC patients and enriched for EpCAM expression by antibody magnetic beads (affinity)-based methods and large RNAs (> 200 nt) sequenced (50 bp paired ends) after rRNA depletion (RiboZero). Expression differences between patients with miliary and non-miliary peritoneal tumor spreading were used for a search for new targeted therapies and for biological annotion.
