Abstract

Background/Aims: Dialysis triggers stress reaction, matrix remodeling and endothelial damage, but little is known about the changes it induces on selected heat shock proteins (Hsp90α), adhesion molecules (E-cadherin, sE-selectin), metalloproteinases (MMP-8) and their extracellular inducer (EMMPRIN). The aim of this study was to assess serum concentrations of the above-mentioned parameters in children on chronic dialysis. Methods: 19 patients on hemodialysis (HD), 22 children on peritoneal dialysis (PD) and 30 age-matched controls were examined. Serum concentrations of parameters were assessed by ELISA. Results: Hsp90α, MMP-8, EMMPRIN and E-cadherin concentrations were significantly increased in children on dialysis vs. controls and higher levels were in HD than PD patients. There was no difference in the level of sE-selectin between HD and PD modalities. A single HD session diminished Hsp90α, MMP-8, EMMPRIN and E-cadherin values, but had no impact on sE-selectin levels. Conclusions: Hemodialysis evokes stress reaction, matrix and endothelium destruction, to a greater extent than peritoneal dialysis. Single hemodialysis influences circulating cells rather than endothelial cells.

Anoikis: an emerging hallmark in health and diseases.

M Taddei, E Giannoni, T Fiaschi … (2012)

Anoikis is a programmed cell death occurring upon cell detachment from the correct extracellular matrix, thus disrupting integrin ligation. It is a critical mechanism in preventing dysplastic cell growth or attachment to an inappropriate matrix. Anoikis prevents detached epithelial cells from colonizing elsewhere and is thus essential for tissue homeostasis and development. As anchorage-independent growth and epithelial-mesenchymal transition, two features associated with anoikis resistance, are crucial steps during tumour progression and metastatic spreading of cancer cells, anoikis deregulation has now evoked particular attention from the scientific community. The aim of this review is to analyse the molecular mechanisms governing both anoikis and anoikis resistance, focusing on their regulation in physiological processes, as well as in several diseases, including metastatic cancers, cardiovascular diseases and diabetes.

Interaction of heat shock proteins with peptides and antigen presenting cells: chaperoning of the innate and adaptive immune responses.

Pramod Srivastava (2001)

Heat shock proteins are abundant soluble intracellular proteins, present in all cells. Members of the heat shock protein family bind peptides including antigenic peptides generated within cells. Heat shock proteins also interact with antigen presenting cells through CD91 and other receptors, eliciting a cascade of events including re-presentation of heat shock protein-chaperoned peptides by MHC, translocation of NF kappa B into the nuclei and maturation of dendritic cells. These consequences point to a key role of heat shock proteins in fundamental immunological phenomena such as activation of antigen presenting cells, indirect presentation (or cross-priming), and chaperoning of peptides during antigen presentation. Heat shock proteins appear to have been involved in innate immune responses since the emergence of phagocytes in early multicellular organisms and to have been commandeered for adaptive immune responses with the advent of specificity. These properties of heat shock proteins also allow them to be used for immunotherapy of cancers and infections in novel ways.

Dual role of heat shock proteins as regulators of apoptosis and innate immunity.

Francois Ghiringhelli, Grégoire Mignot, Anne-Laure Joly … (2009)

Stress or heat shock proteins (HSPs) 70 and 90 are powerful chaperones whose expression is induced in response to a wide variety of physiological and environmental insults. These proteins have different functions depending on their intracellular or extracellular location. Intracellular HSPs have a protective function. They allow the cells to survive potentially lethal conditions. The cytoprotective functions of HSPs can largely be explained by their anti-apoptotic properties. HSP70 and HSP90 can directly interact with different proteins of the tightly regulated programmed cell death machinery and thereby block the apoptotic process at distinct key points. In cancer cells, where the expression of HSP70 and/or HSP90 is frequently abnormally high, they participate in oncogenesis and in resistance to chemotherapy. Therefore, the inhibition of HSPs has become an interesting strategy in cancer therapy. In contrast to intracellular HSPs, extracellularly located or membrane-bound HSPs mediate immunological functions. They can elicit an immune response providing a link between innate and adaptive immune systems. In cancer, most immunotherapeutical approaches based on extracellular HSPs exploit their carrier function for immunogenic peptides. This review will focus on the roles of HSP70 and HSP90 in apoptosis and in innate immunity and how these functions are being exploited in cancer therapy. (c) 2010 S. Karger AG, Basel.
