Characterization of macrophage - cancer cell crosstalk in estrogen receptor positive and triple-negative breast cancer

ABSTRACT: We performed whole transcriptome sequencing of human monocytes that were co-cultured with estrogen receptor positive (ER+) or triple-negative (TNBC) breast cancer cell lines and studied the biological responses related to the differential gene activation in both cell types to understand how different cancer cells educate host cells to support tumor growth To characterize the differences in macrophage activation under the influence of either ER+ or TNBC breast cancer cells, we cultured freshly isolated human peripheral monocytes with two breast cancer cell lines (T47D, ER+ and MDA-MB-231, TNBC) in an in vitro transwell co-culture assay. The transwell setting allowed us to investigate the effect of soluble mediators on macrophage activation since direct cell contact of these cells was inhibited by a (PET) membrane (pore size 0.4âÎ¼m).

Tumor heterogeneity may broadly influence the activation of tumor-associated macrophages. We aimed to dissect how breast cancer cells of different molecular characteristics contribute to macrophage phenotype and function. Therefore, we performed whole transcriptome sequencing of human monocytes that were co-cultured with estrogen receptor positive (ER(+)) or triple-negative (TNBC) breast cancer cell lines and studied the biological responses related to the differential gene activation in both mo ...[more]

Targeting the SIN3A-PF1 Interaction inhibits Epithelial to Mesenchymal Transition and Maintenance of a Stem Cell Phenotype in Triple Negative Breast Cancer (MNase-seq)

Project description:Triple negative breast cancer (TNBC) is characterized by a poorly differentiated phenotype and limited treatment options. Aberrant epigenetics in this subtype represent a potential therapeutic opportunity, but a better understanding of the mechanisms contributing to the TNBC pathogenesis is required. The SIN3 molecular scaffold performs a critical role in multiple cellular processes, including epigenetic regulation, and has been identified as a potential therapeutic target. Using a competitive peptide corresponding to the SIN3 interaction domain of MAD (Tat-SID), we investigated the functional consequences of selectively blocking the paired amphipathic helix (PAH2) domain of SIN3. Here, we report the identification of the SID-containing adaptor PF1 as a factor required for maintenance of the TNBC stem cell phenotype and epithelial to mesenchymal transition (EMT). Tat-SID peptide blocked the interaction between SIN3A and PF1, leading to epigenetic modulation and transcriptional downregulation of TNBC stem cell and EMT markers. Importantly, Tat-SID treatment led to a reduction in primary tumor growth and disseminated metastatic disease in vivo. In support of these findings, knockdown of PF1 expression phenocopied treatment with Tat-SID both in vitro and in vivo. These results demonstrate a critical role for a complex containing SIN3A and PF1 in TNBC and provide a rational for its therapeutic targeting. Mononucleosomes from MDA-MB-231 cells were isolated and ChIP with H3K4me3 antibody. DNA from Input and ChIP samples was purified and sequenced on Illumina Hiseq.

Differential transcript stability measurements in MDA-MB-231 vs. MDA-LM2 cells

Project description:We performed whole-genome stability measurements for MDA-MB-231 and its highly metastatic derivative MDA-LM2. Our goal was to identify post-transcriptonal regulons that are deregulated en route to higher metastatic capacity. Cells were pulsed with 4-thiouridine for 2 hours and then RNA was extracted at 0, 2, 4, and 7 hr time-points in quadruplicate from each cell line. 4sU labeling followed by RNA-seq was then used to measure the abundance of transcripts in each population. A decay rate was estimated based on the rate at which transcript abundance was reduced at these time-points.

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.

Intact extracellular vesicle cross-linking on vesicles derived from MDA-MB-231 and LM2 cells

Project description:The development of any pharmaceutical requires characterization of the compound, usually be several techniques. Therefore, characterizing the protein content and biochemical state of EVs is of great importance for their useif they are to be used as biopharmaceuticals. Structural characterization of proteins in EVs remains a great challenge even for state-of-the-art technologies such as super-resolution and electron microscopy, partly due to the biophysical and biochemical heterogeneity of EVs. Here we overcome some of these challenges by using cross-linking mass spectrometry (XL-MS) to structurally characterize protein complexes and the interactome of intact EVs, at an unprecedented resolution of up to 30Å. By applying XL-MS to intact EVs derived from two metastatic breast cancer cell lines (MDA-MB-231 and LM2), we validate the presence of active forms of protein complexes that are known to play a role metastasis, revealing for example previously uncharacterized regions of Moesin. Moreover, a cross-linking data-driven molecular docking supports novel conformations of ANXA2 in LM2 EVs.

The effect of cannabinoid receptor agonists on triple-negative breast cancer cell line (MDA-MB-231)

Project description:The endocannabinoid system (ECS) provides regulatory functions in several cellular and physiological processes. It has also been found to play a role in control of cancer development. Our group found that breast cancer cells responded to cannabinoid receptor (CB) agonist treatments. This leads the activation of CB receptors in breast cancer, which inhibited their growth. In addition, breast cancer cells also behaved differentially when they were exposed to combinations of both CB1 and CB2 agonists. The underlying mechanism of individual- or co- activation after CB agonist exposure is still unknown. Hence, we studied the impact of CB activation on cancer molecular signature by performing proteomic analysis after triple-negative breast cancer (MDA-MB-231) cells exposed to CB receptor agonists. In this study, ACEA and GW405833 were used as CB1 and CB2 receptor agonists, respectively.

Proteomic analysis of proteome of THP-1 macrophages incubated with Paracoccidioides brasiliensis yeast cells alive or heat-killed

Project description:Paracoccidioides spp. is the etiological agent of Paracoccidioidomycosis (PCM), a systemicinfection with wide distribution in Latin America. Macrophages are very important cells during the response to infection by Paracoccidoides brasiliensis and understanding the interaction between the fungus and immune cells is very relevant for understanding the disease. In this study, we performed a proteomic analysis to assess the consequences of P. brasiliensis yeast infection on the THP-1 macrophage proteome and to verify whether there are differences between the proteome of cells infected with the live fungus. We identified 443 upregulated and 2247 downregulated proteins in macrophages infected with live P. brasiliensis yeasts, compared to uninfected macrophages. Proteins differentially expressed in cells infected are related to metabolism and energy production, protein synthesis and processing, transcription, cell cycle, DNA processing, cell signaling, oxidative stress, immune response, among other processes . Proteomic analysis revealed that P. brasiliensis, causes metabolic alterations in infected cells, drastically affecting energy production pathways. In addition, macrophages showed many upregulated, mostly downregulated, immune system proteins. Thus, the present work contributes to elucidate the changes that occur in immune cells in response to infection by P. brasiliensis and may help to better understand PCM.

The melanoma cell line MDA-MB-435 adhesome in long-term culture and its comparison to the adhesome upon integrin αV knockdown

Project description:Using mass spectrometry–based proteomics, we analysed the components of integrin adhesion complexes of MDA-MB-435S cells and two MDA-MB-435S-derived integrin αV-specific shRNA-expressing cell clones. Among integrins, we detected αV and β5 integrin subunits in the MDA-MB-435S adhesome, thus showing that in long term culture these cells use preferentially integrin αVβ5 for adhesion. Our data represents the first published adhesome of αVβ5 integrin heterodimer.
