DIFFERENTIAL INFLUENCE OF HYPOXIA ON GENE EXPRESSION OF TUMORAL AND NON TUMORAL MAMMARY CELLS

Cancer metastasis is the result of a series of deregulated biological phenomena, including alterations of cell-cell and cell-matrix interactions and of other microenvironmental conditions such as the oxygen tissue supply. Hypoxia is a well-known driver of aggressive cancer phenotypes, indeed tumors with poor prognosis have higher proportions of anoxic and hypoxic areas1. The consequences of tumour hypoxia can be local or even systemic towards distant organs, and it can evoke diversified responses: whereas low oxygen concentration in tissue environments. (pO2 <7 mmHg) exerts anti-proliferative effects and promotes differentiation, apoptosis and/or necrosis on normal cells, the tumoral cells …

Comparative Proteomics of Surgical Fragments of Colorectal Cancer with Non-tumoral Mucosa and Associated Liver Metastasis

Erratum: Donor age and long-term culture do not negatively influence the stem potential of limbal fibroblast-like stem cells (Stem Cell Research and Therapy (2016) 7 (8))

Following publication of the original article in Stem Cell Research and Therapy [1], it was brought to our attention that panel 5E in Fig. 5 is a duplicate of panel 5F. Please find below the figure with the correct panel E. We apologize for the inconvenience this may have caused.

COMPARATIVE PROTEOMIC PROFILING OF NORMAL AND BREAST CANCER CELLS UNDER HYPOXIC CONDITIONS

influences emanating from the tissue microenvironment, such as cell-cell and cell-matrix interactions and other local pathophysiologic conditions as hypoxia. However the hypoxic effect may be different according to the cell conditions. For example, the low concentration of tissue oxygen (pO2 <7 mmHg) may exert anti-proliferative effects on normal cells and may induce differentiation or apoptosis and necrosis. On the other contrary, tumour cells likely react to hypoxic stress with an adaptive process through modification of gene expression that may confer an aggressive phenotype to cells, promoting their local and distant spread [1]. In general it is believed that hypoxic microenvironments i…

COMPARATIVE PROFILING BY PROTEOMICS AND ZYMOGRAPHIC ACTIVITIES OF TUMORAL AND NON TUMORAL CELL LINES

The extracellular matrix (ECM) underlying epithelial tissues is involved in the maintenance of cell polarity and homeostasis. ECM is a dynamic structure under the regulated remodeling of its components. The major enzymes responsible of matrix degradation are the matrix metalloproteinases (MMPs), a well known family of zinc-dependent endopeptidases. Much attention has been focused on MMP-2 and MMP-9 because of their ability to degrade type IV collagen, a major constituent of basement membranes. A deregulated proteolysis of ECM molecules may cause the alteration of cell polarity and may contribute to the disruption of cell–cell and cell–ECM adhesions, promoting cancer progression. These alter…
