Retrospective Proteomic Screening of 100 Breast Cancer Tissues.
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.

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

Large-scale proteomic identification of S100 proteins in breast cancer tissues
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…
Erratum to: Donor age and long-term culture do not negatively influence the stem potential of limbal fibroblast-like stem cells
In 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.Fibroblast-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 evaluated; cytofluorimetric…
CIRCULATING AND TISSUE FORMS OF MMP2 AND MMP9 IN BREAST CANCER PROGRESSION
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.
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…
New Insights into the Occurrence of Matrix Metalloproteases -2 and -9 in a Cohort of Breast Cancer Patients and Proteomic Correlations
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 …
Differential occurrence of S100A7 in breast cancer tissues: A proteomic-based investigation
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…

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

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

Permissive and restrictive influences from breast cancer stroma
The turn-over of extracellular matrix is a physiological process, that in normal conditions and in wound healing respond to spatial and temporal regulatory mechanisms, involving several cell-matrix interaction pathways. Profound changes occur both at cellular and extracellular level, during the progression of various forms of invasive carcinomas. Collagen alterations and cellular effects. The ultrastructural and biochemical analyses of the collagenous stroma of invasive ductal breast carcinoma have demonstrated the occurrence of extensive fragmentation of pre-existing collagen fibrils and new deposition of thinner fibrils formed mostly by 1(I)3 homotrimer collagen of type I [1-3], which app…
