Serum heat shock protein 27 levels in patients with hepatocellular carcinoma. Cell Stress Chaperones 2013; 18:235-41. [PMID: 23073653 PMCID: PMC3581631 DOI: 10.1007/s12192-012-0377-8] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2012] [Revised: 09/27/2012] [Accepted: 09/27/2012] [Indexed: 12/11/2022] Open
Abstract
Levels of serum heat shock protein 27 (sHsp27) have been studied in numerous cancer types, but their potential relevance in patients with hepatocellular carcinoma (HCC) is undetermined. Our aim was to compare sHsp27 levels in patients with HCC and HCC-free controls. Specifically, we recruited 71 patients with HCC (80 % with early tumour), 80 patients with chronic liver disease (59 with liver cirrhosis and 21 with chronic active hepatitis) and 42 healthy subjects. sHsp27 was measured by immunoenzymatic assay. Results showed that sHsp27 levels were significantly (p < 0.001) higher in patients with HCC than in the other groups, particularly in those with hepatitis C virus (HCV)-related disease. In HCC patients, sHsp27 levels were not associated with prognostic risk factors, such as size/multiplicity of nodules and stage. In logistic regression analysis, performed in patients with liver disease, log-sHsp27 was associated with a significant age-adjusted 2.5-fold increased odds ratio of HCC and with a significant 4.4-fold higher odds ratio of HCC in the subgroup with HCV-related liver disease. In receiver operating characteristic curve analysis, sensitivity and specificity of the best sHsp27 cut-off value (456.5 pg/ml) for differentiating patients with HCC from those with HCC-free chronic liver disease were 70 and 73 %, respectively. In conclusion, sHsp27 levels are enhanced in patients with HCC and may represent a candidate biomarker of HCC.

Abstract
Heat shock proteins (Hsps) are overexpressed in a wide range of human cancers and are implicated in tumor cell proliferation, differentiation, invasion, metastasis, death, and recognition by the immune system. We review the current status of the role of Hsp expression in cancer with special emphasis on the clinical setting. Although Hsp levels are not informative at the diagnostic level, they are useful biomarkers for carcinogenesis in some tissues and signal the degree of differentiation and the aggressiveness of some cancers. In addition, the circulating levels of Hsp and anti-Hsp antibodies in cancer patients may be useful in tumor diagnosis. Furthermore, several Hsp are implicated with the prognosis of specific cancers, most notably Hsp27, whose expression is associated with poor prognosis in gastric, liver, and prostate carcinoma, and osteosarcomas, and Hsp70, which is correlated with poor prognosis in breast, endometrial, uterine cervical, and bladder carcinomas. Increased Hsp expression may also predict the response to some anticancer treatments. For example, Hsp27 and Hsp70 are implicated in resistance to chemotherapy in breast cancer, Hsp27 predicts a poor response to chemotherapy in leukemia patients, whereas Hsp70 expression predicts a better response to chemotherapy in osteosarcomas. Implication of Hsp in tumor progression and response to therapy has led to its successful targeting in therapy by 2 main strategies, including: (1) pharmacological modification of Hsp expression or molecular chaperone activity and (2) use of Hsps in anticancer vaccines, exploiting their ability to act as immunological adjuvants. In conclusion, the present times are of importance for the field of Hsps in cancer, with great contributions to both basic and clinical cancer research.

Abstract
BACKGROUND The expression of heat shock protein-27 (HSP-27) has been detected in some human tumors. In this study the authors investigated HSP-27 expression in patients with hepatocellular carcinoma (HCC) and examined its prognostic significance. METHODS Expression of HSP-27 was studied in 58 HCC and adjacent noncancerous liver tissues by immunohistochemical stain. The relation between its expression and eight known prognostic factors was evaluated. RESULTS Of the 58 HCC tissues studied, the presence of HSP-27 was demonstrated in 45 tissues (77.6%); low expression (</= 25%) was demonstrated in 17 tissues and high expression (> 25%) was demonstrated in 28 tissues. A significantly higher distribution of HSP-27 expression in HCC tissues compared with adjacent noncancerous liver tissues was obtained (P < 0.0001). Patients with high HSP-27 expression had a significantly higher histologic tumor grade than those with low HSP-27 expression (P = 0.001). The 5-year disease free survival rate of patients with high HSP-27 expression was 21.4% versus 59.3% for patients with low HSP-27 expression (P < 0.001). A similar relation was observed with overall survival (33.3% vs. 64. 8%; P = 0.009). HSP-27 expression was also identified to be a significant and powerful prognostic indicator for disease free survival (odds ratio = 2.25; P = 0.034) and for overall survival (odds ratio = 2.72; P = 0.015). CONCLUSIONS The current study data suggest that HSP-27 expression is a powerful prognostic indicator and is related to histologic grade and survival of patients with HCC.

Abstract
Molecular mechanisms of basal and D-amphetamine (AMPH)-induced apoptosis were studied in rat liver nodules, 12 (N12) and 30 (N30) weeks after initiation, and in hepatocellular carcinoma (HCC) induced by diethylnitrosamine in rats subjected to resistant hepatocyte model. Basal apoptosis in hematoxylin/eosin- and propidium iodide-stained sections was higher in nodules and HCC than in normal livers. It sharply increased in all tissues 4 hours after AMPH treatment (10 mg/kg), and declined to basal levels at 8 to 12 hours in liver and N12, but remained high up to 18 hours in N30 and HCC. c-myc, Tgf-alpha, p53, and Bcl-X(S) messenger RNA (mRNA) levels were higher, and Bcl-2 mRNA was lower in N12 and/or N30 and HCC than in normal liver. Four hours after AMPH injection, increase in c-myc and decreases in Bcl-2 and Bcl-X(L) mRNAs occurred in all tissues, whereas p53, Bax, and Bcl-X(S) mRNAs increased in N30 and HCC. These changes disappeared in liver and N12 at 18 hours, but persisted in N30 and HCC. c-Myc, P53, Bcl-2, and Bax proteins in normal liver and HCC +/- AMPH showed similar patterns. Tgf-beta1, Tgf-beta-RIII, CD95, and CD95L mRNA levels underwent slight or no changes in any tissue +/- AMPH. Basal Hsp27 expression was high in nodules and HCC, and was stimulated by AMPH in liver and N12, but not in N30 and HCC. These data suggest a role of dysregulation of Bcl-2 family genes and, at least in atypical lesions, of p53 overexpression, in basal and AMPH-induced apoptosis in nodules and HCCs. Hsp27 does not appear to sufficiently protect atypical lesions against apoptosis.

Abstract
This work was aimed at testing the hypothesis (hitherto supported only by indirect evidence) that, besides contributing to resistance to stress, the small heat-shock-protein HSP27 might be involved in the control of growth and differentiation in mammary-tumour cells, where it is known to be oestrogen-regulated. Therefore, MCF-7 cells were transfected with a modulatable human hsp27 anti-sense cDNA. Clones of transfectants (designated alphahsp27) were selected which, upon expression of the anti-sense, exhibited a decline in HSP27 accumulation, associated with a decrease in resistance to heat shock and in proliferation rate, the degree of the latter reflecting their respective reduction in HSP27 content. The effects of anti-sense inhibition of HSP27 production were similar to those exerted on parental cells by phorbol myristate (TPA). Both resulted in growth inhibition, accumulation of lipid droplets in the cytoplasm, formation of secretory microvesicles with internal microvilli and increased release of several proteins, including the isoforms of a 52-kDa protein, which we identified as the oestrogen-regulated protein cathepsin D, all this without noticeable change in actin organization. These data constitute the first direct support for the hypothesis that, at least in some cell types, HSP27 might play a modulatory role in cell differentiation and (perhaps by this) in proliferation. While allowing dissociation of this role from the known action of HSP27 on actin polymerization, they suggest similar modulation of the function of some protein(s) implicated in the acquisition of the secretory phenotype by MCF-7 cells, with HSP27 also exerting an inhibitory action that can be alleviated either by its phosphorylation (as occurs with TPA) or by inhibition of its production.

Abstract
Molecular chaperones are ubiquitous, well-conserved proteins that account for 2-5 % of all cellular proteins in most cells. The present review summarizes our current knowledge about their involvement in the etiology and therapy of cancer with special emphasis on the expression of chaperones in malignant cells, their role in folding of (proto)oncogene products, cell cycle regulation, cell differentiation and apoptosis, development of metastasis, and their participation in the recognition of malignant cells. We also overview the importance of chaperones in hyperthermia, drug resistance, and recent approaches in chaperone-immunotherapy.

Abstract
The expression of two small stress proteins, alpha B crystallin and the 27-kDa heat shock protein (HSP27), was studied quantitatively and immunohistochemically in normal kidney and renal tumors in rats. Levels of alpha B crystallin in renal cell tumors tended to be higher than in normal kidney (P = 0.07), but with a wide range of values, whereas they were significantly lower in mesenchymal tumors (P < 0.0001). In contrast, HSP27 concentrations in both renal cell (mean +/- SD: 1790 +/- 940 ng/mg protein, n = 15) and mesenchymal (1260 +/- 1080 ng/mg protein, n = 10) tumors were significantly higher than the normal kidney value (142 +/- 30 ng/mg protein, n = 10, P < 0.0001). A positive correlation was found between alpha B crystallin and HSP27 levels limited to the renal cell tumor case (Pearson's correlation coefficient, r = 0.68, P < 0.01). Immunohistochemistry revealed the loops of Henle to be positive for alpha B crystallin, whereas HSP27 staining was positive in glomerular and interstitial vascular walls and epithelial cells of proximal and distal tubules. Positive immunostaining for alpha B crystallin was demonstrated in six of nine renal cell tumors (67%) studied and for HSP27 in all of the nine cases (100%).

Abstract
The distribution of heat shock proteins (HSP) HSP60, HSP73, HSP72 and HSP25 in the isoosmotic cortex and the hyperosmotic medulla of the rat kidney was investigated using Western blot analysis and immunohistochemistry. HSP73 was homogeneously distributed throughout the whole kidney. The level of HSP60 was high in the renal cortex and low in the medulla. HSP25 and HSP72 were present in large amounts in the medulla. Only low levels of HSP25 and almost undetectable amounts of HSP72 were found in the cortex. HSP25 exists in one nonphosphorylated and several phosphorylated isoforms. Western blot analysis preceded by isoelectric focussing showed that HSP25 predominates in its nonphosphorylated form in the outer medulla but in its phosphorylated form in cortex and inner medulla. Although this intrarenal distribution pattern was not changed during prolonged anaesthesia (thiobutabarbital sodium), a shift from the nonphosphorylated to the phosphorylated isoforms of HSP25 occurred in the medulla. The characteristic intrarenal distribution of the constitutively expressed HSPs (HSP73, HSP60, HSP25) may reflect different states of metabolic activity in the isoosmotic (cortex) and hyperosmotic (medulla) zones of the kidney. The high content of inducible HSP72 in the medulla most likely is a consequence of the osmotic stress imposed upon the cells by the high urea and salt concentrations in the hyperosmotic medullary environment.

Abstract
The 27-kDa heat shock protein (HSP27) is a member of the small heat shock protein (HSP) family. In addition to its putative function in thermotolerance, this protein may play a part in the regulation of cell growth and differentiation. This study was conducted to assess the significance of the expression of HSP27 in human epidermis and in cutaneous neoplasms. Sixty-two biopsy samples from normal human skin and from inflammatory and neoplastic skin diseases were investigated by immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, using a monoclonal antibody specific for HSP27. In normal human epidermis, HSP27 is expressed in the upper epidermal layers with a cytoplasmic staining pattern. The basal cell layer does not express detectable amounts of HSP27. In hair follicles, staining is mainly confined to the outer root sheath and to the infundibular epithelium. Melanocytes, dermal fibroblasts and endothelial cells do not express detectable amounts of HSP27. HSP27 could not be detected in fetal skin until the 20th week of gestation. Tumour cells in basal and squamous cell carcinomas do not express significant amounts of HSP27. In solar keratoses, seborrhoeic keratoses, human papillomavirus (HPV)-induced hyperproliferative lesions and inflammatory skin conditions, HSP27 expression largely resembles the pattern observed in normal human skin. HSP27 is expressed in a differentiation-related pattern in normal human epidermis and hyperproliferative disorders of the epidermis. We conclude that HSP27 may be regarded as a marker of differentiation in epidermal keratinocytes. Absence of HSP27 in the upper epidermal layers may be a marker for epidermal malignancy.
