Hypoxia is one of the most important features of the tumor microenvironment, exerting an adverse effect on tumor aggressiveness and patient prognosis. Two types of hypoxia may occur within the tumor mass, chronic (prolonged) and cycling (transient, intermittent) hypoxia. Cycling hypoxia has been shown to induce aggressive tumor cell phenotype and(More)
BACKGROUND/AIM It has been shown that HSPA2 protein, a testis-enriched member of HSPA/HSP70 family, is important for cancer cell growth and metastasis. However, the status of HSPA2 expression in tumors and its clinical/prognostic significance are obscure. Herein we aimed to investigate the expression of HSPA2 in various types of tumors and to determine the(More)
Hypoxia can influence aggressiveness of melanoma by inducing specific gene expression profiles. In our previous microarray study, we identified more than 430 hypoxia-responsive genes in the B16-F10 murine melanoma cell line in vitro. Of the genes identified, seven genes: galectin 3 (Lgals3), melanoma cell adhesion molecule (Mcam), fibronectin 1 (Fn1),(More)
Anthracycline chemotherapeutics, e.g. doxorubicin and daunorubicin, are active against a broad spectrum of cancers. Their cytotoxicity is mainly attributed to DNA intercalation, interference with topoisomerase activity, and induction of double-stranded DNA breaks. Since modification of anthracyclines can profoundly affect their pharmacological properties we(More)
HSPA2 belongs to the multigene HSPA family, whose members encode chaperone proteins. Although expression and function of HSPA2 is mainly associated with spermatogenesis, recent studies demonstrated that in humans, the gene is active in various cancers, as well as in normal tissues, albeit in a cell type-specific manner. In the epidermis, HSPA2 is expressed(More)
HSPA2, a poorly characterized member of the HSPA (HSP70) chaperone family, is a testis-enriched protein involved in male germ cell differentiation. Previously, we revealed that HSPA2 is present in human stratified epithelia, including epidermis, however the contribution of this protein to epithelial biology remained unknown. Here, we show for the first time(More)
