Bioinformatics analysis of BARX1 as a novel omental metastasis biomarker in high-grade serous ovarian cancer

ABSTRACT: Omentum is one of the most preferred metastatic sites in patients with high-grade serous ovarian cancer, while the underlying mechanisms remain poorly understood. Here, we aim to identify biomarkers related to omental metastasis in high-grade serous ovarian cancer. In this study, we constructed a risk model comprising FAM9A, BARX1, SNORA79, CIDEA, FABP4, and TRARG1 as risk factors for omental metastasis using the machine-learning methods LASSO and Random Forest. And we identified BARX1 (BarH-like homeobox 1) as the gene with the highest predictive value. Further studies validated the high expression of BARX1 across pan-cancers and its association with immune cell infiltration using CIBERSORT analysis. Our research underscores the crucial role of BARX1 in OC and highlights its potential as a therapeutic target.

Identification of gene signature in microdissected omental adipose tissue from high grade serous ovarian cancer patients

Project description:Advanced ovarian cancer usually spreads to the omentum. However, the omental cell-derived molecular determinants modulating its progression have not been thoroughly characterized. Transcriptome profiling was performed on microdissected omental adipose tissue obtained from patients with benign gynecologic diseases and on cancer-associated omental tissue obtained from patients with advanced-stage, high grade serous ovarian cancer.

Analysis of ECM-enriched samples using different methods

Project description:Using LC-MS/MS, we analyzed ECM-enriched samples obtained from 1) human triple-negative breast cancer samples and matched adjacent normal mammary gland tissues, and 2) disease-free omentum from patient with non-metastatic ovarian cancer and high-grade- serous-ovarian- cancer-derived omental metastasis samples. We conducted the LC-MS/MS analysis on peptides obtained after solubilizing ECM-enriched samples using different methods (crude ECM extract, urea-soluble extract, urea-insoluble extract) and submitted to basic-reversed- phase separation or not.

NanoString expression profiling in metastatic ovarian cancer

Project description:Purpose: Most molecular characterizations of high-grade serous ovarian cancer (HGSOC) have been done in primary ovarian tumors. Such data may not be fully representative of HGSOC, which is characterized by widespread peritoneal metastases at the time of diagnosis and upon relapse. The most common site of HGSOC metastasis is the omentum. The omentum is characterized by strong immune and fibrotic activities and is a rich source of mesenchymal stem cells (MSCs), which have the capacity to differentiate into cancer-associated fibroblasts (CAFs) and promote ovarian cancer progression. The omentum is also rich in tertiary lymphoid structures (TLS), which are transient aggregates of leukocytes structurally and functionally comparable to secondary lymphoid tissues. Experimental design: With the goal of elucidating expression patterns in a large number of omental metastases, we profiled expression of immune- and cancer progression-related genes in pretreatment omental metastasis samples from 152 patients diagnosed with HGSOC.

Omentum gel enables the study of metastatic ovarian cancer and stromal cell functions in a physiologically relevant environment

Project description:High-grade serous (HGS) ovarian cancer is the most common and aggressive ovarian cancer type, and the most lethal gynaecological disease 1,2. The major cause is its highly metastatic nature and the limited availability of effective therapies to oppose it. The omentum is a highly vascularised visceral depot of adipose tissue with immune functions, which becomes the preferential metastatic site in patients with HGS ovarian cancer 1,2. The omentum provides an environment that supports the rapid growth of metastatic tumours and their spread within the peritoneal cavity and adjacent organs 2,3. Research aimed at understanding the biology of metastatic tumours in the omentum is therefore essential to find strategies to oppose HGS ovarian cancer. To this aim, there is the need for in vitro models that faithfully recapitulate the microenvironment of HGS omental metastasis in patients.

Omentum-derived matrix enables the study of metastatic ovarian cancer and stromal cell functions in a physiologically relevant environment

Project description:High-grade serous (HGS) ovarian cancer is the most lethal gynaecological disease in the world and metastases is a major cause. The omentum is the preferential metastatic site in HGS ovarian cancer patients and in vitro models that recapitulate the original environment of this organ at cellular and molecular level are being developed to study basic mechanisms that underpin this disease. The tumour extracellular matrix (ECM) plays active roles in HGS ovarian cancer pathology and response to therapy. However, most of the current in vitro models use matrices of animal origin and that do not recapitulate the complexity of the tumour ECM in patients. Here, we have developed omentum gel (OmGel), a matrix made from tumour-associated omental tissue of HGS ovarian cancer patients that has unprecedented similarity to the ECM of HGS omental tumours and is simple to prepare. When used in 2D and 3D in vitro assays to assess cancer cell functions relevant to metastatic ovarian cancer, OmGel performs as well as or better than the widely use Matrigel and does not induce additional phenotypic changes to ovarian cancer cells. Surprisingly, OmGel promotes pronounced morphological changes in cancer associated fibroblasts (CAFs). These changes were associated with the upregulation of proteins that define subsets of CAFs in tumour patient samples, highlighting the importance of using clinically and physiologically relevant matrices for in vitro studies. Hence, OmGel provides a step forward to study the biology of HGS omental metastasis. Metastasis in the omentum are also typical of other cancer types, particularly gastric cancer, implying the relevance of OmGel to study the biology of other highly lethal cancers.

Hematogenous metastasis of ovarian cancer: Re-thinking mode of spread

Project description:Ovarian cancer has a clear predilection for metastasis to the omentum, but the underlying mechanisms involved in ovarian cancer spread are not well understood. Here, we used a parabiosis model that demonstrates preferential hematogenous metastasis of ovarian cancer to the omentum. Our studies revealed that the ErbB3-neuregulin1 (NRG1) axis is a dominant pathway responsible for hematogenous omental metastasis. Elevated levels of ErbB3 in ovarian cancer cells and NRG1 in the omentum allowed for tumor cell localization and growth in the omentum. Depletion of ErbB3 in ovarian cancer substantially impaired omental metastasis. Our results highlight hematogenous metastasis as a previously under-recognized mode of ovarian cancer metastasis. These findings have implications for designing new strategies aimed at preventing and treating ovarian cancer metastasis.
