Cancer cell stiffening via CoQ10 and UBIAD1 regulates ECM signaling and ferroptosis resistance in Breast Cancer

ABSTRACT: Here, we discovered that CoQ10 and its biosynthetic enzyme UBIAD1 play a critical role in plasma membrane mechanical properties that are of interest for breast cancer (BC) progression and treatment. In detail, CoQ10 and UBIAD1 increased membrane fluidity leading to increased cell stiffness in BC. High UBIAD1/CoQ10 states impair lipid rafts and ECM-mediated oncogenic signaling and reduce the ferroptosis resistance of BC cells. Furthermore, analyses on BC patients and BC mouse models reveal that UBIAD1 loss is associated with BC development and progression. UBIAD1 expression in aggressive BC limits CTCs survival and lung metastasis formation in experimental xenograft assays.

Feedback amplication of fibrosis through matrix stiffening and COX-2 suppression

Project description:We tested the hypothesis that increasing matrix stiffness on which normal human lung fibroblasts are grown promotes the expression of a fibrogenic cellular transcriptomic program. Keywords: Human lung fibroblast, matrix stiffness, PTGS2, COX-2, Prostaglandin E2 Total RNA extracted from normal human lung fibroblasts from 3 human subjects and separately grown on 5 discrete matrix stiffness conditions: 100, 400, 1600, 6400, 25600 Pascals.

Human Pancreatic CTCs Express the ECM Protein SPARC

Project description:Circulating Tumor Cells (CTCs) are shed from primary tumors into the bloodstream, mediating the hematogenous spread of cancer to distant organs. To determine the relevance of ECM protein expression to human disease, CTCs were isolated from the blood of metastatic PDAC patients and subjected to single cell RNA-sequencing. Analysis of 7 pancreatic CTCs from 3 patients revealed that the majority expressed keratins defining their epithelial origin. A total of 13 of 60 extracellular protein genes enriched in mouse CTCs (see GEO GSE51372) were expressed at high levels (>100 rpm) in at least one human pancreatic CTC. Human SPARC was the only gene found at high levels in all human pancreatic CTCs. To achieve a deep RNA sequencing profile of CTCs at the single cell level, we applied a novel inertial focusing-enhanced device, the CTC-iChip, which allows high efficiency negative depletion of normal blood cells, leaving unattached CTCs in solution where they can be selected and analyzed as single cells (Pubmed ID 23552373). CTCs were then subjected to single cell RNA-sequencing (Pubmed ID 20203668).

Extracellular matrix (ECM) stiffness and collagen-1 (col-1) responsive genes in 3D cultured mammary epithelial cells

Project description:We report the expression profiles of MCF10A cells encapsulated in hydrogels of varying stiffness and composition. Cells were encapsulated for 7 days in either 1.) soft alginate and reconstituted basement membrane (rBM), 2.) stiff alginate and rBM, 3,) soft col-1 and rBM, or 4.) stiff col-1. We find global gene expression changes in response to enhanced ECM stiffness, independent of expression changes in response to col-1 exposure. These results provide a comprehensive study of the gene expression changes associated with increased ECM stiffness in addition to the gene expression changes associated with increased col-1 concentration in combination with, and independent of, ECM stiffness.

Detection and isolation of circulating tumor cells from breast cancer patients using CUB domain-containing protein 1 (CDCP1) Detection and isolation of circulating tumor cells from breast cancer patients using CUB domain-containing protein 1 (CDCP1) Detection and isolation of circulating tumor cells from breast cancer patients using CUB domain-containing protein 1 (CDCP1)

Project description:Circulating tumor cells (CTCs) and disseminated tumour cells with mesenchymal traits are difficult to detect by epithelial marker proteins. Particularly, triple negative breast cancers (TNBC) that are prone to therapy failure release a subpopulation of circulating tumour cells (CTCs) with mesenchymal traits. To provide tools that support their detection and analysis, the cell line BC-M1 established from disseminated tumour cells in the bone marrow of a breast cancer patient and a bone metastasis subline of MDA-MB-231 were analysed. Mass spectrometry analysis revealed high levels of CUB domain-containing protein 1 (CDCP1) in BC-M1. CDCP1 was found in other carcinoma cell lines (MDA-MB-231, MDA-MB-468) and other DTC cell lines (LC-M1, PC-E1) as well. Peripheral blood mononuclear cells were virtually negative for CDCP1 by Western Blot and immunofluorescent staining. Presence of CDCP1 in CTCs was confirmed by CellSearch. Here, CDCP1 positive CTCs were detected in eight of 30 analysed breast cancer patients. For the isolation of CTCs from the blood of breast cancer patients, we established a sandwich magnetic-activated cell sorting (MACS). The extracellular domain of CDCP1 served for cell catching and the cytoplasmic domain of CDCP1 for immunofluorescent detection of CDCP1 in CTCs. We showed that the MACS approach is suitable for the isolation of EpCam/keratin negative breast cancer cells from the blood and isolated CDCP1 positive CTCs from breast cancer patients by MACS. Hence, our approach is particularly suited for the detection and isolation of CTCs from TNBC when low EpCam or keratin levels limit the application of conventional approaches.

Human colorectal cancer progression correlates with LOX-induced ECM stiffening.

Project description:Some solid tumors are characterized by extracellular matrix (ECM) remodeling and stiffening, which is related to solid tumor progression and aggression. However, the relationship between ECM stiffness and colorectal cancer (CRC) remains unclear. In this study, we investigated the relevance of ECM stiffness to clinicopathologic features using human CRC tissue microarrays. The results demonstrate that the expression of ECM components in CRC tissues is closely correlated with CRC progression and poor prognosis, which indicates that ECM stiffness may be associated with CRC development. We further studied lysyl oxidase (LOX) expression in CRC tissue and demonstrated that LOX expression is closely correlated with CRC progression. Previous studies showed that P-selectin-mediated platelet accumulation in CRC tissue may up-regulate LOX expression. Our findings indicate that P-selectin-mediated platelet aggregation may up-regulate LOX expression and enhance the remodeling and stiffening of the tumor ECM, which may promote the progression of colorectal cancer. Therefore, LOX may be a potential effective therapeutic target to treat colorectal cancer.

Disturbed flow promotes arterial stiffening through thrombospondin-1 (TSP-1) signaling pathways

Project description:Arterial stiffness is a prevalent, independent cardiovascular risk factor, but the underlying mechanisms are not well understood. Wall shear stress and shear-sensitive genes may promote arterial stiffening through clinically important signaling pathways. Our goal was to identify how disturbed blood flow leads to arterial stiffness using the mouse partial carotid ligation model. Here we used our in vivo partial carotid ligation model to induce d-flow in the LCA while the contralateral RCA continues to experience stable laminar flow using the C57BL/6x129SvEv mice, TSP-1 knockout (KO), and C57Bl/6J mice. We compared these to aged (80 week) mice which had increased arterial stiffness due to aging. Changes in gene expression were identified using microarrays that were performed on the endothelial-enriched RNA isolated from the carotids exposed to stable flow (RCA) and compared to disturbed flow (LCA). Arterial stiffness was determined ex vivo by biaxial mechanical testing and in vivo by ultrasound techniques. Myointimal hyperplasia and immunohistochemistry were performed in sectioned carotid arteries. In vitro testing of signaling pathways utilized oscillatory and laminar wall shear stress. Human arteries were tested ex vivo to validate critical results found in the animal model.
