A multiomics analysis of S100 protein family in breast cancer

2018

The S100 gene family is the largest subfamily of calcium binding proteins of EF-hand type, expressed in tissue and cell-specific manner, acting both as intracellular regulators and extracellular mediators. There is a growing interest in the S100 proteins and their relationships with different cancers because of their involvement in a variety of biological events closely related to tumorigenesis and cancer progression. However, the collective role and the possible coordination of this group of proteins, as well as the functional implications of their expression in breast cancer (BC) is still poorly known. We previously reported a large-scale proteomic investigation performed on BC patients f…

Fibroblast’s role in breast cancer: a proteomic approach

2008

Fibroblasts are the major mesenchymal cell types committed to the matrix formation and renewal. Moreover they are the main source of paracrine factors that influence the growth of epithelial cells of neighbouring tissues. For these properties they may be involved in tumourigenesis, either by remodelling the tumor-associated extracellular matrix (ECM), and by the production of paracrine factors that influence the growth of carcinoma cells. Studies on fibroblasts associated to carcinomas have documented their phenotypic modifications, including abnormal migratory behaviour in vitro and growth factors altered expression(Schor & Schor, 2001). In addition, fibroblasts often recruit inflammat…

Proteomic analysis of extracellular vesicles shed in vitro by MDA MB 231 breast carcinoma cells

2010

Cross talk between tumor cells and connective tissue plays a key role in tumor progression. The communication is due to the release of signalling molecules from both tumor cells and surrounding stromal cells. Several secreted proteins lack the N-terminal signal peptides and, therefore, they are secreted by alternative unconventional processes such as secretion mechanism mediated by vesicle shedding in the extracellular matrix. Actually, a certain number of proteins, playing roles in some aspects of tumor progression, have been found in shed vesicles. For example, EMMPRIN, carried out in vesicles shed by tumor cells, stimulates matrix metalloproteinase (MMP) production in stromal fibroblasts…

Retrospective Proteomic Screening of 100 Breast Cancer Tissues.

2017

The present investigation has been conducted on one hundred tissue fragments of breast cancer, collected and immediately cryopreserved following the surgical resection. The specimens were selected from patients with invasive ductal carcinoma of the breast, the most frequent and potentially aggressive type of mammary cancer, with the objective to increase the knowledge of breast cancer molecular markers potentially useful for clinical applications. The proteomic screening; by 2D-IPG and mass spectrometry; allowed us to identify two main classes of protein clusters: proteins expressed ubiquitously at high levels in all patients; and proteins expressed sporadically among the same patients. Wit…

The exponentially increasing volume of information extracted from genomic and proteomic applications on cancer, while providing new insights into molecular composition of cancer cells and tissues, imposes new challenges on data rationalization as a tool for clinically relevant biomarker discovery. Breast cancer represents the most frequent and potentially aggressive type of cancer and, moreover, it is one of the most enigmatic and poorly predictable in its evolution, likely because it includes several different forms that behave differently among patients. Current clinical parameters for breast cancer diagnosis and cure are: tumour size, axillary lymph node status, histological grading and …

Prognostic and Functional Significant of Heat Shock Proteins (HSPs) in Breast Cancer Unveiled by Multi-Omics Approaches

2021

Simple Summary In this study, we investigated the expression pattern and prognostic significance of the heat shock proteins (HSPs) family members in breast cancer (BC) by using several bioinformatics tools and proteomics investigations. Our results demonstrated that, collectively, HSPs were deregulated in BC, acting as both oncogene and onco-suppressor genes. In particular, two different HSP-clusters were significantly associated with a poor or good prognosis. Interestingly, the HSPs deregulation impacted gene expression and miRNAs regulation that, in turn, affected important biological pathways involved in cell cycle, DNA replication, and receptors-mediated signaling. Finally, the proteomi…

S100S PROTEIN EXPRESSION IN A LARGE SAMPLE-SET OF BREAST CANCER TISSUES

2010

S100 proteins are low molecular weight proteins ranging in size from 9 to 13 kDa. They form homo- and heterodimers and even oligomers and are expressed in tissue and cell-specific manner [1]. It is well documented, infact, that S100 proteins have a broad range of intracellular and extracellular functions. Intracellular functions include regulation of protein phosphorylation, enzyme activity, calcium homeostasis, regulation of cytoskeletal components and regulation of transcriptional factors, so they are involved in several biological processes including cell cycle regulation, cell growth, cell differentiation, and motility [2]. Extracellularly they act in a cytokine like manner through the …

Anticancer activity of biogenerated silver nanoparticles: an integrated proteomic investigation

2018

Silver nanoparticles (AgNPs), embedded into a specific polysaccharide (EPS), were biogenerated by Klebsiella oxytoca DSM 29614 under aerobic (AgNPs-EPSaer) and anaerobic conditions (AgNPs-EPSanaer). Both AgNPs-EPS matrices were tested by MTT assay for cytotoxic activity against human breast (SKBR3 and 8701-BC) and colon (HT-29, HCT 116 and Caco-2) cancer cell lines, revealing AgNPs-EPSaer as the most active, in terms of IC50, with a more pronounced efficacy against breast cancer cell lines. Therefore, colony forming capability, morphological changes, generation of reactive oxygen species (ROS), induction of apoptosis and autophagy, inhibition of migratory and invasive capabilities and prote…

Extracellular Vesicles Shed by Melanoma Cells Contain a Modified Form of H1.0 Linker Histone and H1.0 mRNA-binding Proteins

2016

Extracellular vesicles (EVs) are shed in the extracellular environment by both prokaryotes and eukaryotes. Although produced from both normal and cancer cells, malignant cells release a much higher amount of EVs, which also contain tumor-specific proteins and RNAs. We previously found that G26/24 oligodendroglioma cells shed EVs that contain the pro-apoptotic factors FasL and TRAIL1-2. Interestingly, G26/24 release, via EVs, extracellular matrix remodelling proteases3, and H1° histone protein4, and mRNA. To shed further light on the role of EVs in discarding proteins and mRNAs otherwise able to counteract proliferative signals, we studied a melanoma cell line (A375). We found that also thes…

In Vitro Phenotypic, Genomic and Proteomic Characterization of a Cytokine-Resistant Murine β-TC3 Cell Line

2012

Type 1 diabetes mellitus (T1DM) is caused by the selective destruction of insulin-producing β-cells. This process is mediated by cells of the immune system through release of nitric oxide, free radicals and pro-inflammatory cytokines, which induce a complex network of intracellular signalling cascades, eventually affecting the expression of genes involved in β-cell survival. The aim of our study was to investigate possible mechanisms of resistance to cytokine-induced β-cell death. To this purpose, we created a cytokine-resistant β-cell line (β-TC3R) by chronically treating the β-TC3 murine insulinoma cell line with IL-1β + IFN-γ. β-TC3R cells exhibited higher proliferation rate and resistan…

Proteomic differentiation pattern in the U937 cell line

2011

The U937 cell line, originally established from a histiocytic lymphoma, has been widely used as a powerful in vitro model for haematological studies. These cells retain the immature cell phenotype and can be induced to differentiate by several factors, among which 12-O-tetradecanoyl-13-phorbol acetate (TPA). Fully differentiated cells acquire the adherent phenotype and exhibit various properties typical of macrophages. However, in spite of a great deal of research devoted to the U937 cellular model, the molecular basis of biological processes involved in the monocyte/macrophage differentiation remains unclear. The present study has been undertaken to contribute to this knowledge, in order t…

Background: Current clinical parameters for breast cancer diagnosis and therapy are: tumour size, axillary lymph node status, histological grading and presence or absence of metastases. Prognostic/predictive properties, such as oestrogen and progesterone receptor status, and human epidermal growth factor receptor (HER-2/neu) status are currently used for therapeutic decision. Conversely, it is now emerging that the number of genetic mutations and epigenetic deregulations in cancer is far more higher than previously thought. Therefore, proteomic screening for differential protein expression in subsets of tumor samples is an essential tool for generating data bases and biomarker discovery. Th…

Oxidation Enhances Human Serum Albumin Thermal Stability and Changes the Routes of Amyloid Fibril Formation

2014

Oxidative damages are linked to several aging-related diseases and are among the chemical pathways determining protein degradation. Specifically, interplay of oxidative stress and protein aggregation is recognized to have a link to the loss of cellular function in pathologies like Alzheimer's and Parkinson's diseases. Interaction between protein and reactive oxygen species may indeed induce small changes in protein structure and lead to the inhibition/modification of protein aggregation process, potentially determining the formation of species with different inherent toxicity. Understanding the temperate relationship between these events can be of utmost importance in unraveling the molecul…

Large-scale proteomic identification of S100 proteins in breast cancer tissues

2010

Abstract Background Attempts to reduce morbidity and mortality in breast cancer is based on efforts to identify novel biomarkers to support prognosis and therapeutic choices. The present study has focussed on S100 proteins as a potentially promising group of markers in cancer development and progression. One reason of interest in this family of proteins is because the majority of the S100 genes are clustered on a region of human chromosome 1q21 that is prone to genomic rearrangements. Moreover, there is increasing evidence that S100 proteins are often up-regulated in many cancers, including breast, and this is frequently associated with tumour progression. Methods Samples of breast cancer t…

CIRCULATING AND TISSUE FORMS OF MMP2 AND MMP9 IN BREAST CANCER PROGRESSION

2010

Tumor progression and metastasis represent the leading causes of cancer related death. One of the major features that may contribute to neoplastic cell dissemination is the progressive and local degradation of the extracellular matrix (ECM) surrounding the primary tumour. Degradation of the ECM requires the coordinated action of a number of enzymes produced locally by neoplastic cells and/or stromal cells. Five categories of proteinases have been implicated in the invasive process: serine, cysteine, aspartic, threonine proteinases and matrix metalloproteinases (MMPs), also known as matrixins, which play a key role as terminal effectors of the proteolytic cascade. At present 23 members of th…

Differential proteomic and phenotypic behaviour of papillary and anaplastic thyroid cell lines.

2013

Abstract Thyroid carcinomas account for a minority of all malignant tumours but, after those of the gonads, they represent the most common forms of endocrine cancers. They include several types, among which the papillary thyroid cancer (PTC) and the anaplastic thyroid cancer (ATC) are the best known. The two hystotypes display significant biological and clinical differences: PTC is a well differentiated form of tumour with a high incidence and a good prognosis, while the ATC is less frequent but represents one of the most aggressive endocrine tumours with morphological features of an undifferentiated type. To date, as far as we know, no conclusive studies, useful to design arrays of molecul…

Exploring the anticancer activity and the mechanism of action of pyrrolomycins F obtained by microwave-assisted total synthesis

2023

Pyrrolomycins (PMs) are a family of naturally occurring antibiotic agents, isolated from the fermentation broth of Actinosporangium and Streptomyces species. Pursuing our studies on pyrrolomycins, we performed the total synthesis of the F-series pyrrolomycins (1–4) by microwave-assisted synthesis (MAOS), thus obtaining the title compounds in excellent yields (63–69%). Considering that there is no evidence so far of the anticancer effect of this class of compounds, we investigated PMs for their antiproliferative activity against HCT116 and MCF-7 cancer cell lines. PMs showed anticancer activity at submicromolar level with a minimal effect on normal epithelial cell line (hTERT RPE-1), and the…

New protein clustering of breast cancer tissue proteomics using actin content as a cellularity indicator

2008

In the present study, we report the comparative proteome profiles of proteins solubilized from 37 breast cancer surgical tissues, normalized for the actin content. Blood-derived proteins were excluded from the analysis. Among the tumor-derived protein spots, a large proportion (39%) was found present in all patients. These included several glycolytic enzymes, detox and heat shock proteins, members of annexin and S100 protein families, cathepsin D, and two “rare” proteins, DDAH2 involved in the angiogenesis control, and the oncogene PARK7. Other proteins, such as psoriasin, galectin1, cofilin, peroredoxins, SH3L1, and others, showed sporadic presence and high expression level, which suggests…

New Insights into the Occurrence of Matrix Metalloproteases -2 and -9 in a Cohort of Breast Cancer Patients and Proteomic Correlations

2018

Matrix metalloproteases (MMPS) are a family of well-known enzymes which operate prevalently in the extracellular domain, where they fulfil the function of remodeling the extracellular matrix. Within the about 26 family members, encoded by 24 genes in humans, MMP-2 and MMP-9, have been regarded as the primary responsibility for the basement membrane and pericellular ECM rearrangement. In cases of infiltrating carcinomas, which arise from the epithelial tissues of a gland or of an internal organ, a marked alteration of the expression and the activity levels of both MMPs is known to occur. Present investigation represents the continuation and upgrading of our previous studies, now focusing on …

Purpose The present study reports for the first time a large-scale proteomic screening of the occurrence, subcellular localization and relative quantification of the S100A7 protein among a group of 100 patients, clinically grouped for the diagnosis of infiltrating ductal carcinoma (IDC). Experimental design To this purpose, the methods of differential proteomics, Western blotting, and immunohistochemistry were used. Results The identity of two isoforms of the protein was assessed by mass spectrometry and immunologically confirmed. Moreover, we proved by immunocytochemical applications the exclusive localization of the protein within the neoplastic cells. The correlation of S100A7 expression…

Ectopic decorin induces proteomic and phenotypic modulation of breast cancer cells.

2005

Breast cancer cells exhibit selective modulation induced by different collagen substrates.

2008

During the invasive phase of malignant tumors, neoplastic cells break into the basal lamina and enter in contact with the underlying connective tissue, which concurrently undergoes extensive modifications. The aim of our present minireview is to focus the changes in the collagenous matrix occurring during breast cancer progression and to explore the possible effects of different collagen substrates on breast cancer cell behavior and proteomic modulation.

Decorin transfection induces proteomic and phenotypic modulation in breast cancer cells 8701-BC

2008

Decorin is a prototype member of the small leucine-rich proteoglycan family widely distributed in the extracellular matrices of many connective tissues, where it has been shown to play multiple important roles in the matrix assembly process, as well as in some cellular activities. A major interest for decorin function concerns its role in tumorigenesis, as growth-inhibitor of different neoplastic cells, and potential antimetastatic agent. The aim of our research was to investigate wide-ranged effects of transgenic decorin on breast cancer cells. To this purpose we utilized the well-characterized 8701-BC cell line, isolated from a ductal infiltrating carcinoma of the breast, and two derived …

Herceptin-resistance in breast cancer cells: a proteomic study.

2009

HER-2 is a cell membrane protein that belongs to the ErbB family of receptor tyrosine kinases (HER-1, HER-2, HER-3, HER-4). The over-expression of HER-2, which results in the 25-30% of breast cancer patients, is considered a predictive and prognostic marker for breast cancer malignancy and invasiveness and makes HER-2 an excellent therapeutic target. In the last years new therapeutic strategies have been improved in order to better deal tumor diseases an to minimize collateral effects due to classic chemotherapy in patients. In this way, a new approach was the somministration of humanized antibodies directed against tumor-associated molecular targets. Among these ones Herceptin, an anti-neo…

AbstractBackgroundIn regenerative medicine the maintenance of stem cell properties is of crucial importance. Ageing is considered a cause of reduced stemness capability. The limbus is a stem niche of easy access and harbors two stem cell populations: epithelial stem cells and fibroblast-like stem cells. Our aim was to investigate whether donor age and/or long-term culture have any influence on stem cell marker expression and the profiles in the fibroblast-like stem cell population.MethodsFibroblast-like stem cells were isolated and digested from 25 limbus samples of normal human corneo-scleral rings and long-term cultures were obtained. SSEA4 expression and sphere-forming capability were ev…

Multiple effects induced by herceptin® on 8701-BC breast cancer cells

2008

Herceptin, an anti-neoplastic humanized monoclonal antibody (Herceptin®, Roche, CH), has been shown to be active against breast cancer cells over-expressing HER-2 receptor. HER-2 is a cell membrane protein that belongs to the epidermal growth factor receptors family and that results over-expressed in the 25-30% of breast cancer patients. The over-expression of HER-2 is considered a predictive and prognostic marker for breast cancer malignancy and invasiveness. On these bases, we aimed to analyze the effects caused by Herceptin treatment on 8701-BC breast cancer cells (Minafra et al., 1989). Firstly we evaluated the effects of Herceptin on the growth rate of 8701-BC cells. To this purpose, p…

According to recent statistics, breast cancer remains one of the leading causes of death among women in Western countries. Breast cancer is a complex and heterogeneous disease, presently classified into several subtypes according to their cellular origin. Among breast cancer histotypes, infiltrating ductal carcinoma represents the most common and potentially aggressive form. Despite the current progress achieved in early cancer detection and treatment, including the new generation of molecular therapies, there is still need for identification of multiparametric biomarkers capable of discriminating between cancer subtypes and predicting cancer progression for personalized therapies. One esta…

S-100 calcium binding proteins as potential markers for breast cancer metastasis.

2009

The S-100 family of calcium-binding proteins includes about 20 members of low molecular weight characterized by two consecutive EF hands domains. They make interactions with cellular target proteins in a calcium-dependent manner; therefore they are thought to regulate a variety of physiological functions, such as cell proliferation, signal transduction, cell adhesion, motility as well as cancer metastasis.

Colorectal cancer (CRC) develops by genetic and epigenetic alterations. However, the molecular mechanisms underlying metastatic dissemination remain unclear and could benefit from multi-omics investigations of specific protein families. Matrix metalloproteinases (MMPs) are proteolytic enzymes involved in ECM remodeling and the processing of bioactive molecules. Increased MMP expression promotes the hallmarks of tumor progression, including angiogenesis, invasion, and metastasis, and is correlated with a shortened survival. Nevertheless, the collective role and the possible coordination of MMP members in CRC are poorly investigated. Here, we performed a multi-omics analysis of MMP expression…

Nuclear myc promoter-binding protein-1 (MBP-1) expression is a prognostic factor in invasive ductal breast carcinoma

2010

Insulators are DNA elements that block the extension of a condensed chromatin domain into a transcriptionally active region or prevent the interaction of a distal enhancer with a promoter when placed between the two. Human c-Myc and Pvt-1 genes map close each other and are separated by an intergenic region rich of DNAseI hypersensitivity sites. Starting from the observation that PVT1 expression is restricted to a low number of normal tissues compared to the wide distribution of c-Myc mRNA we focus our studies on the function and structure of the regions surrounding the DHs present between the two genes. Stable and transient transfection, indicate that one of the regions (HB-2.8) has enhance…

Multiple changes induced by fibroblasts on breast cancer cells.

2010

It is now widely recognised that the cross-talk between cancer and stromal cells may play a crucial role in cancer progression. However little is known about the complex underlying molecular mechanisms that occur within the tumor microenvironment. Fibroblasts are the major stromal cells with multiple roles, especially towards both the extracellular matrix and the neighbouring cell population, including neoplastic cells. Consequently, proteomic analyses would provide a wider resource for a better understanding of the potential modulating effects exerted by fibroblasts on cancer cells. In this report we describe the effects of fibroblast stimulation on the breast cancer cell line (8701-BC) pr…
