Bulk RNAseq of FNE1 cells with ectopic expression of YAP1 and HPV E6/E7 oncogenes

ABSTRACT: High grade serous ovarian carcinoma (HGSOC) is the most common and aggressive ovarian malignancy. Accumulating evidence indicates that HGSOC may originate from human fallopian tube epithelial cells (FTECs), although the exact pathogen(s) and/or molecular mechanism underlying the malignant transformation of FTECs is unclear. Here we show that human papillomavirus (HPV), which could reach FTECs via retrograde menstruation or sperm-carrying, interacts with the yes-associated protein 1 (YAP1) to drive the initiation and progression of high grade serous cancer (HGSC). HPV prevents FTECs from natural replicative and YAP1-induced senescence, thereby promoting YAP1-induced malignant Transformation of FTECs. HPV also stimulates proliferation and drives metastasis of YAP1-transformed FTECs. YAP1, in turn, stimulates the expression of the putative HPV receptors and suppresses the innate immune system to facilitate HPV acquisition. These findings provide critical clues for developing new strategies to prevent and treat HGSOC.

ECM-enriched proteomics of human fallopian tube, fimbria and ovarian tissue

Project description:We analysed the extracellular matrix (ECM) landscape of fresh, healthy tissues from human fallopian tube (FT), fimbria (FB, the tissue of origin of serous tubal intraepithelial lesions) and ovarian tissue (OV). The aim was to identify differentially expressed matrix proteins between FB and FT or OV which may promote the neoplastic transformation of serous tubal intraepithelial lesions (STICs) into high-grade serous ovarian cancer, HGSOC, and metastasis from the FB to the OV.

PRKCI promotes immune suppression in ovarian cancer through YAP1

Project description:A key feature of high-grade serous ovarian carcinoma (HGSOC) is frequent amplification of the 3q26 locus harboring PRKC-iota (PRKCI). Here, we show that PRKCI is also expressed in early fallopian tube lesions, called Serous Tubal Intraepithelial Carcinoma. Transgenic mouse studies establish PRKCI as an ovarian cancer specific oncogene and system level and functional analyses identify YAP1 as a downstream effector in tumor progression. Mechanistically, the oncogenic activity of the PRKCI-YAP1 axis relates in part to the upregulation of TNFα to promote an immune suppressive tumor microenvironment characterized by an abundance of myeloid-derived suppressor cells and inhibition of cytotoxic T cell infiltration. In human ovarian cancers, high PRKCI expression also correlates with high expression of YAP1 and low infiltration of cytotoxic T-cell. The PRKCI-YAP1 regulation of the tumor immunity provides a therapeutic strategy for highly lethal ovarian cancer. Robust multi-array average (RMA) method was used with default options (with background correction, quantile normalization, and log transformation) to normalize raw data from batches using R/Bioconductor‘s affy package

LncRNA and mRNA expression profiles in High-grade serous ovarian cancer, Low-grade serous ovarian cancer and Normal fallopian tube

Project description:Ovarian cancer is the most lethal gynecologic cancer. High-grade serous ovarian carcinoma (HGSOC) is the most common histologic subtype, accounting for three quarters of ovarian cancer. To clarify the changes of gene expression in serous ovarian cancer, we performed lncRNA and mRNA microarrays to identify differentially expressed lncRNAs and mRNAs in High-grade and Low-grade serous ovarian carcinoma compared with Normal fallopian tube.

microRNA profiling of serum microRNA from high grade serous ovarian carcinoma

Project description:High-grade serous ovarian carcinoma (HGSOC) is the most lethal gynecologic neoplasm, with five-year survival rate below 30%. Early disease detection is of utmost importance to improve the cure rate of HGSOC. Liquid biopsies are now becoming a new paradigm to develop novel biomarkers with diagnostic and prognostic purposes. The focus of this study was to detect the levels of circulating miRNAs in tissues and sera from patients with HGSOC and to evaluate their diagnostic value. To this end, an array-based discovery platform, followed by an innovative statistical approach of data normalization, was exploited, to identify miRNA species selectively expressed in serum of patients with HGSOC. Sera from 106 high grade serous ovarian carcinoma (HGSOC) and 24 healthy controls were used for profiling serum microRNA using a modified version of a commercially available microarray, with the aim of identifying differentially expressed microRNA between tumor patients and healthy controls.

Effect of platelets on 3D models of ovarian cancer

PRKCI regulates tumor microenvironment through YAP1 [Affymetrix]

Project description:A key feature of serous ovarian cancer is frequent amplification in the 3q26 locus, which harbors the PRKCI gene. Here we show that PRKCI is amplified and overexpressed in a 78% of high-grade serous ovarian carcinoma. Our in vivo studies with orthotopic mouse models establish it as an ovarian cancer oncogene. This oncogenic property of PRKCI is mediated by regulation of YAP1 activity. Accordingly YAP1 knockdown partially rescues PRKCI mediated tumorigenesis. Integrated gene expression profiling and YAP1 promoter occupancy analyses reveal that PRKCI and YAP1 cooperate to transcriptionally regulate genes affecting the tumor immune microenvironment. Consistently, CD11b+Gr1+Ly6G+ MDSCs are increased in the tumor microenvironment of PRKCI over-expressing tumors. Importantly, we show that elevated PRKCI expression in high-grade serous ovarian carcinomas strongly correlated with assignment to immunoreactive subtype. In summary, we identify PRKCI and YAP1 as key mediators of a tumor-promoting immunosuppressive microenvironment in ovarian cancers.

Methylomic analysis of ovarian cancers identifies tumor-specific alterations readily detectable in early precursor lesions

Project description:High-grade serous ovarian carcinoma (HGSOC) typically remains undiagnosed until advanced stages when peritoneal dissemination has already occurred. Here, we sought to identify HGSOC-specific alterations in DNA methylation and assess their potential to provide sensitive and specific detection HGSOC at its earliest stages.
