Abstract
Background Heat shock proteins (Hsp) are chaperones playing essential roles in skeletal muscle physiology, adaptation to exercise or stress, and activation of inflammatory cells. We aimed to assess Hsp90 in patients with idiopathic inflammatory myopathies (IIM) and its association with IIM-related features. Methods Hsp90 plasma levels were analyzed in a cross-sectional cohort (277 IIM patients and 157 healthy controls [HC]) and two longitudinal cohorts to assess the effect of standard-of-care pharmacotherapy (n=39 in early disease and n=23 in established disease). Hsp90 and selected cytokines/chemokines were measured by commercially available ELISA and human Cytokine 27-plex Assay. Results Hsp90 plasma levels were increased in IIM patients compared to HC (median [IQR]: 20.2 [14.3–40.1] vs 9.8 [7.5–13.8] ng/mL, p<0.0001). Elevated Hsp90 was found in IIM patients with pulmonary, cardiac, esophageal, and skeletal muscle involvement, with higher disease activity or damage, and with elevated muscle enzymes and crucial cytokines/chemokines involved in the pathogenesis of myositis (p<0.05 for all). Plasma Hsp90 decreased upon pharmacological treatment in both patients with early and established disease. Notably, Hsp90 plasma levels were slightly superior to traditional biomarkers, such as C-reactive protein and creatine kinase, in differentiating IIM from HC, and IIM patients with cardiac involvement and interstitial lung disease from those without these manifestations. Conclusions Hsp90 is increased systemically in patients with IIM. Plasma Hsp90 could become an attractive soluble biomarker of disease activity and damage and a potential predictor of treatment response in IIM.

Abstract
Various molecular and cellular processes are involved in renal fibrosis, such as oxidative stress, inflammation, endothelial cell injury, and apoptosis. Heat shock proteins (HSPs) are implicated in the progression of chronic kidney disease (CKD). Our aim was to evaluate changes in urine and serum HSP levels over time and their relationships with the clinical parameters of CKD in children. In total, 117 children with CKD and 56 healthy children were examined. The CKD group was followed up prospectively for 24 months. Serum and urine HSP27, HSP40, HSP47, HSP60, HSP70, HSP72, and HSP90 levels and serum anti-HSP60 and anti-HSP70 levels were measured by ELISA at baseline, 12 months, and 24 months. The urine levels of all HSPs and the serum levels of HSP40, HSP47, HSP60, HSP70, anti-HSP60, and anti-HSP70 were higher at baseline in the CKD group than in the control group. Over the months, serum HSP47 and HSP60 levels steadily decreased, whereas HSP90 and anti-HSP60 levels steadily increased. Urine HSP levels were elevated in children with CKD; however, with the exception of HSP90, they decreased over time. In conclusion, our study demonstrates that CKD progression is a complicated process that involves HSPs, but they do not predict CKD progression. The protective role of HSPs against CKD may weaken over time, and HSP90 may have a detrimental effect on the disease course.

Abstract
Atopic dermatitis (AD) is one of the most common chronic inflammatory dermatoses characterized by persistent itching and recurrent eczematous lesions. While the primary events and key drivers of AD are topics of ongoing debate, cutaneous inflammation due to inappropriate IgE (auto)antibody-related immune reactions is frequently considered. Highly conserved and immunogenic heat shock protein 90 (Hsp90), a key intra- and extracellular chaperone, can activate the immune response driving the generation of circulating anti-Hsp90 autoantibodies that are found to be elevated in several autoimmune disorders. Here, for the first time, we observed that serum levels of Hsp90 and anti-Hsp90 IgE autoantibodies are significantly elevated (p < 0.0001) in AD patients (n = 29) when compared to age- and gender-matched healthy controls (n = 70). We revealed a positive correlation (0.378, p = 0.042) between serum levels of Hsp90 and the severity of AD assessed by Scoring Atopic Dermatitis (SCORAD). In addition, seropositivity for anti-Hsp90 IgE has been found in 48.27% of AD patients and in 2.85% of healthy controls. Although further studies on a larger group of patients are needed to confirm presented data, our results suggest that extracellular Hsp90 and autoantibodies to Hsp90 deserve attention in the study of the mechanisms that promote the development and/or maintenance of atopic dermatitis.

Abstract
Our previous study demonstrated increased expression of Heat shock protein (Hsp) 90 in the skin of patients with systemic sclerosis (SSc). We aimed to evaluate plasma Hsp90 in SSc and characterize its association with SSc-related features. Ninety-two SSc patients and 92 age-/sex-matched healthy controls were recruited for the cross-sectional analysis. The longitudinal analysis comprised 30 patients with SSc associated interstitial lung disease (ILD) routinely treated with cyclophosphamide. Hsp90 was increased in SSc compared to healthy controls. Hsp90 correlated positively with C-reactive protein and negatively with pulmonary function tests: forced vital capacity and diffusing capacity for carbon monoxide (DLCO). In patients with diffuse cutaneous (dc) SSc, Hsp90 positively correlated with the modified Rodnan skin score. In SSc-ILD patients treated with cyclophosphamide, no differences in Hsp90 were found between baseline and after 1, 6, or 12 months of therapy. However, baseline Hsp90 predicts the 12-month change in DLCO. This study shows that Hsp90 plasma levels are increased in SSc patients compared to age-/sex-matched healthy controls. Elevated Hsp90 in SSc is associated with increased inflammatory activity, worse lung functions, and in dcSSc, with the extent of skin involvement. Baseline plasma Hsp90 predicts the 12-month change in DLCO in SSc-ILD patients treated with cyclophosphamide.

Abstract
BACKGROUND AND AIMS The heat shock protein (Hsp) 90α is induced by stress and regulates inflammation through multiple pathways. Elevated serum Hsp90α had been found in nonalcoholic steatohepatitis (NASH). Geranylgeranylacetone (GGA, also called teprenone) is a terpenoid derivative. It was reported to induce Hsp and alleviate insulin resistance. We aimed to evaluate the Hsp90α as a biomarker in predicting metabolic-associated fatty liver disease (MAFLD) and define the therapeutic effects of geranylgeranylacetone for the disease. METHODS A clinical study was conducted to analyze the elements associated with Hsp90α, and a predictive model of MAFLD was developed based on Hsp90α. The histopathological correlation between Hsp90α and MAFLD was investigated through a diet-induced mouse model. Furthermore, GGA was applied to the mouse model. RESULTS Serum Hsp90α was increased in patients with MAFLD. A positive linear relationship was found between age, glycosylated hemoglobin (HbA1c), MAFLD, and serum Hsp90α. Meanwhile, a negative linear relationship with body mass index (BMI) was found. A model using Hsp90α, BMI, HbA1c, and ALT was established for predicting MAFLD. The area under the receiver operating characteristic (ROC) curves was 0.94 (95% CI 0.909-0.971, p = 0.000). The sensitivity was 84.1%, and the specificity was 93.1%. In vitro experiments, GGA induced Hsp90α in steatosis cells. In the mice model, Hsp90α decreased in the GGA treatment group. Hepatic steatosis, inflammation, insulin resistance, and glucose intolerance were improved in the GGA-treated group. Serum Hsp90α was positively correlated with steatohepatitis activity according to hepatic histopathology. CONCLUSIONS Serum Hsp90α was elevated in MAFLD, and a positive correlation between serum Hsp90α and the grade of activity of steatohepatitis was observed. The model using BMI, HbA1c, and alanine aminotransferase (ALT) had a good value to predict MAFLD. The findings also revealed the effectiveness of GGA in the treatment of MAFLD.

Abstract
NLRP3, one of the HSP-90 clients, has been defined as a critical component of IBD. In a rat model of DSS-induced colitis, we investigated the anti-inflammatory potential of the combined therapy with CP-456773 (CP), an NLRP3 inhibitor, and celastrol (CSR), an NF-κB inhibitor. Our results revealed that the CSR/CP combined therapy (CCCT) attenuated colon shortening, DAI and MDI in addition to improvement of the colonic histological picture. Moreover, the CCCT increased the antioxidant defense machinery of the colonic tissue and decreased MPO activity. Furthermore, the inflammation markers such as TNF-α and IL-6 were downregulated. These effects might be attributed to the inhibitory effect of CSR on the priming step of the NLRP3 inflammasome activation by interrupting NF-κB signalling and inhibition of HSP-90 (at the protein and mRNA levels) along with inhibitory effect of CP on the expression of the NLRP3. These latter effects resulted in decreased tissue expression and activity of the caspase-1 and repressing the subsequent release of the active forms of IL-1β and IL-18, hence, the pyroptosis process is restrained. Additionally, the CCCT resulted in inducing autophagy by AMPK/mTOR-dependent mechanisms leading to the accumulation of BECN1 protein and a significant decrease in the levels of p62 SQSTM1. The inhibitory effect on HSP-90 in conjunction with induction of autophagy suggest increased autophagic degradation of NLRP3. This novel approach provides a basis for the clinical application of this combination in IBD treatment and might also be promising for the pharmacological intervention of other NLRP3 inflammasome-dependent inflammatory conditions.

Abstract
Heat shock proteins play an important role in immune inflammation and the formation and restoration of proteins. In recent years, the importance of heat shock protein 90 (Hsp90) in the activation of immune inflammation through nuclear factor kB (NFkB) has been discussed. To assess the activation of the Hsp90-NFkB system by measuring serum and urinary levels in patients with chronic glomerulonephritis (CGN). This study included 32 patients with active forms of CGN and 14 patients with Fabry nephropathy. The control group included 10 healthy individuals. Twenty-one out of 32 CGN patients had nephrotic syndrome (NS). Eleven out of 32 CGN patients had proteinuria levels from 1 to 3 g/day without nephrotic syndrome. A total of 17 patients had renal dysfunction (estimated glomerular filtration rate < 60 ml/min/1.73m2). Fourteen patients with Fabry nephropathy had proteinuria without nephrotic syndrome. Serum and urine HSP-90 and NFkB p65 levels were determined using an enzyme-linked immunosorbent assay. The levels of HSP-90 and NFkB in the serum of patients with CGN were significantly higher than in healthy individuals and patients with Fabry nephropathy. In patients with Fabry nephropathy, the HSP-90 and NFkB levels in the urine and serum did not significantly differ from those in the control subjects. Serum Hsp90 levels were significantly higher in the CGN patients with NS than in patients without NS, as well as in patients with normal renal function compared with patients with an eGFR < 60 ml/min/1.73 m2 and patients with tubulo-interstitial fibrosis. Higher levels of HSP-90 and NFkB in serum were observed in patients with nephrotic forms of CGN, including focal segmental glomerulosclerosis, minimal change disease and membranous nephropathy. There were no correlations between the clinical signs of CGN and urinary HSP90/NFkB levels. Activation of the HSP-90-NFkB system, which is directly involved in the development of immune inflammation in CGN, was found in patients with an active course of CGN, especially in those with nephrotic syndrome.

Abstract
Chronic kidney disease (CKD) is an important public health problem in the world. The aim of our research was to identify novel potential serum biomarkers of renal injury. ELISA assay showed that cytokines and chemokines IL-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, Eotaxin, FGFb, G-CSF, GM-CSF, IP-10, MCP-1, MIP-1α, MIP-1β, PDGF-1bb, RANTES, TNF-α and VEGF were significantly higher (R > 0.6, p value < 0.05) in the serum of patients with CKD compared to healthy subjects, and they were positively correlated with well-established markers (urea and creatinine). The multiple reaction monitoring (MRM) quantification method revealed that levels of HSP90B2, AAT, IGSF22, CUL5, PKCE, APOA4, APOE, APOA1, CCDC171, CCDC43, VIL1, Antigen KI-67, NKRF, APPBP2, CAPRI and most complement system proteins were increased in serum of CKD patients compared to the healthy group. Among complement system proteins, the C8G subunit was significantly decreased three-fold in patients with CKD. However, only AAT and HSP90B2 were positively correlated with well-established markers and, therefore, could be proposed as potential biomarkers for CKD.

Abstract
Alongside with the emergent clinical trials for Machado-Joseph disease/Spinocerebellar ataxia type 3 (MJD/SCA3) comes the need to identify molecular biomarkers of disease that can be tracked throughout the trial. MJD is an autosomal dominant neurodegenerative disorder caused by expansion of a CAG repeat in the coding region of the ATXN3 gene. Previous findings indicate the potential of transcriptional alterations in blood of MJD patients as biomarkers of disease. Accurate quantification of gene expression levels by quantitative real-time PCR (qPCR) depends on data normalization, usually performed using reference genes. Because the expression level of routinely used housekeeping genes may vary in multiple biological and experimental conditions, reference gene controls should be validated in each specific experimental design. Here, we aimed to evaluate the expression behavior of five housekeeping genes previously reported as stably expressed in peripheral blood of patients from several disorders-peptidylprolyl isomerase B (PPIB), TNF receptor associated protein 1 (TRAP1), beta-2-microglobulin (B2M), 2,4-dienoyl-CoA reductase 1 (DECR1), and folylpolyglutamate synthase (FPGS). Expression levels of these five genes were assessed by qPCR in blood from MJD subjects (preataxic and patients) and matched controls. While all housekeeping genes, here studied, were stably expressed in our sets of samples, TRAP1 showed to be the most stable gene by NormFinder and BestKeeper. We, therefore, conclude that any of these genes could be used as reference gene in future qPCR studies using blood samples from MJD subjects.

Abstract
PURPOSE The objective of present study is to determine serum levels and placental distribution of two interacting proteins calcyclin and heat shock protein 90 in preeclampsia. EXPERIMENTAL DESIGN Maternal serum levels of calcyclin and heat shock protein 90 are compared throughout pregnancy from the first trimester till term among women with preeclampsia (n = 43) and age-matched normotensive pregnant controls (n = 46). A serum-based 2D LC-MS assay using Parallel Reaction Monitoring is applied to quantify both calcyclin and heat shock protein 90. RESULTS Serum levels of calcyclin are significantly lower in patients with preeclampsia in the second trimester of pregnancy as compared to controls (p < 0.05). Serum levels of heat shock protein 90 are significantly higher in patients with preeclampsia in the third trimester as compared to controls (p < 0.001). CONCLUSION AND CLINICAL RELEVANCE Both interacting proteins calcyclin and heat shock protein 90 are notably changed in preeclamptic patients compared to controls. Calcyclin is already decreased before the onset of preeclampsia in the second trimester and HSP90 is strongly increased in the third trimester. This suggests that these proteins may play a role in the pathogenesis of preeclampsia and ought to be investigated in large cohort studies as molecular biomarkers.

Abstract
Metabolic surgery ameliorates insulin resistance and is associated with long-term, effective weight loss, but the mechanisms involved remain unknown. Here, the duodenal-jejunal omega switch (DJOS) surgery in combination with high-fat, high-carbohydrate diet was performed on diet obese rats and joint effects of bariatric surgery and different dietary patterns on heat shock protein 70 (HSP70) and HSP90 plasma and liver concentrations were measured. We found that plasma and liver levels of HSP70 were lower after DJOS surgery in comparison to the control in the groups of animals kept on control diet (CD) and high-fat, high-sugar diet (HFS) but the postoperative change of the diet led to the increase in HSP70 in plasma and liver concentration in DJOS-operated animals. A high-calorie meal, rich in carbohydrates and fats, significantly increased circulating levels of HSP90, reducing the normalising effect of DJOS. The HFS diet applied during all stages of the experiment led to the higher levels of liver HSP90 concentration. The combination of CD and DJOS surgery was the most efficient in the lowering of the HSP90 liver concentration. The normalisation of circulating levels and liver concentrations of HSP70 and HSP90 may be achieved in a combination of DJOS procedure with a proper dietary plan.

Abstract
Type 2 diabetes mellitus (T2DM) features insulin resistance, hyperglycemia, dyslipidemia, overproduction of inflammatory cytokines, and systemic oxidative stress. Here, heat shock proteins Hsp70 and Hsp 90, adiponectin, and heme oxygenase-1 (HO-1, Hsp32) are profiled in peripheral blood mononuclear cells (PBMC) and serum from 25 T2DM patients and 25 healthy control subjects. Cells cultured with phorbol 12-myristate 13-acetate/ionomycin were evaluated by three-color flow cytometry for immunophenotypic biomarkers. Plasma HO-1, Hsp, and adiponectin levels were assayed by enzyme-linked immunosorbent assay (ELISA). Relative to healthy controls, T2DM patients exhibited significantly elevated plasma Hsp70, and representation of T helper immunophenotypes activated to express inflammatory cytokines, including CD4+ IFN-γ+, CD4+ TNF-α+, CD4+ IL-6+, CD4+ IL-1β+ T cells, significantly lower representation of CD4+ IL-10+ T cells, plasma adiponectin and cell-associated HO-1 expression-with no significant differences in plasma Hsp90 between T2DM and healthy controls. Plasma HO-1 and adiponectin in T2DM patients inversely correlated with TNF-α and showed inverse correlation between serum LDL and plasma HO-1. Moreover, TNF-α and Hsp90 in T2DM patients correlated positively with fasting blood glucose (FBG). These results demonstrate correlation between potentially pathogenic T cells, HO-1, and adiponectin, additionally revealing a T helper (Th)1-related character of T2DM immunopathogenesis, suggesting potential for novel T cell-related management strategies for T2DM and related co-morbidities.

Abstract
More sensitive biomarker is urgently needed to reduce the mortality caused by the worldwide prevalent liver cancer. This study aims to assess whether quantitative measurement of heat shock protein 90alpha (Hsp90α) in plasma can improve the diagnosis accuracy and monitor treatment response of liver cancer patients. We analyzed the data from an official (registered at ClinicalTrial.gov: NCT02324127), large-scale (1647 enrollments), and multicenter (three independent hospitals) clinical trial, which quantitatively measured plasma Hsp90α by ELISA for patients with liver cancer, patients with at-risk liver diseases (including hepatitis, liver cirrhosis, focal nodular hyperplasia), and healthy individuals. Diagnostic performance of plasma Hsp90α was evaluated by the calculated sensitivity, specificity, and area under the receiver operating characteristic curve (AUC). ROC curve showed plasma Hsp90α can discriminating liver cancer with a sensitivity of 92.7% and specificity of 91.3% from non-liver cancer control. Similar results were noted in detecting early-stage liver cancer (sensitivity 91.4%, specificity 91.3%). In a parallel study compared with AFP20, plasma Hsp90α exhibited a significantly higher diagnostic performance (sensitivity 93.3% vs 61.1%) in discriminating hepatocellular carcinoma (HCC) from the control. Furthermore, plasma Hsp90α measurement maintained distinctly excellent diagnostic accuracy in distinguishing AFP-negative HCC patients (sensitivity 93.9%, specificity 91.3%) and AFP-limited liver cancer (sensitivity 96.6%, specificity 90.3%). In the efficacy monitoring study, levels of plasma Hsp90α were dramatically decreased after surgery (P=0.005), and correlated significantly with tumor size during interventional therapy (P≤0.05). These findings highlight that plasma Hsp90α as a biomarker for the diagnosis of liver cancer, and can be used to evaluate the therapeutic efficacy of liver cancer patients underwent surgery, or interventional therapy.

Abstract
Background Heat shock protein 90 (HSP90), a molecular chaperone associated with the activation of client proteins, was recently reported to play an important role in immunologic reactions. To date, the role of HSP90 in solid organ transplantations has remained unknown. The aim of this study was to evaluate the relationship between serum HSP90α levels and acute allograft rejection after organ and tissue transplantation using serum samples from kidney allograft recipients, an in vitro antibody-mediated rejection model, and a murine skin transplantation. Results Serum HSP90α levels were significantly higher in kidney recipients at the time of acute rejection (AR) than in those with no evidence of rejection. In most cases with AR, serum HSP90 decreased to baseline after the treatment. On the other hand, serum HSP90α was not elevated as much in patients with chronic rejection, calcineurin inhibitor nephrotoxicity, or BK virus nephropathy as in AR patients. In vitro study showed that HSP90α concentration in the supernatant was significantly higher in the supernatant of human aortic endothelial cells cocultured with specific anti-HLA IgG under complement attack than in that of cells cocultured with nonspecific IgG. In mice receiving skin transplantation, serum HSP90α was elevated when the first graft was rejected and the level further increased during more severe rejection of the second graft. Conclusions The results suggest that HSP90α is released into the serum by cell damage due to AR in organ and tissue transplantation, and it is potentially a new biomarker to help detect AR in kidney recipients.

Abstract
Mammalian heat-shock-protein (HSP) 90α rapidly responses to environmental insults. We examined the hypothesis that not only serum HSP72 but also HSP90α is increased in the systemic inflammatory response syndrome (SIRS), severe-sepsis (SS), and/or sepsis (S) compared to healthy children (H); we assessed HSP90α relation to (a) multiple organ system failure (MOSF) and (b) inflammatory-metabolic response and severity of illness.A total of 65 children with S, SS, or SIRS and 25 H were included. ELISA was used to evaluate extracellular HSP90α and HSP72, chemiluminescence interleukins (ILs), flow-cytometry neutrophil-CD64 (nCD64)-expression.HSP90α, along with HSP72, were dramatically increased among MOSF patients. Patients in septic groups and SIRS had elevated HSP90α compared to H (P < 0.01). HSP90α was independently related to predicted death rate and severity of illness; positively to HSP72, nCD64, ILs, length of stay, days on ventilator, and fever; negatively to HDL and LDL (P < 0.05). The HSP72 was increased in SS/S and related negatively to HDL and LDL (P < 0.05).Serum HSP90α is markedly elevated in children with severe sepsis and is associated with MOSF. Better than the HSP72, also increased in SS, SIRS, and MOSF, HSP90α is related to the inflammatory stress, fever, outcome endpoints, and predicted mortality and inversely related to the low-LDL/low-HDL stress metabolic pattern.

Abstract
BACKGROUND Hypertension-induced endothelial dysfunction is associated with an impaired bioavailability of nitric oxide regulated through interactions between nitric oxide synthase and heat shock protein-90 (Hsp-90). The role of Hsp-90 in the development of arterial hypertension remains unclear. OBJECTIVES The objective of the study was to evaluate serum concentrations of Hsp-90a in patients with arterial hypertension in comparison to their normotensive counterparts. MATERIAL AND METHODS The study was performed on 49 adults (mean age 55.6 years) with an elevated waist circumference. The individuals presented no subjective feeling of any disease, admitted no drug treatment for any condition, and had not previously been diagnosed with the metabolic syndrome. Patients were screened for arterial hypertension and other component disorders of the metabolic syndrome. Hsp-90a concentrations were evaluated by enzyme-linked immunosorbent assay (ELISA). RESULTS Twenty-eight subjects were diagnosed with arterial hypertension, while 21 individuals had normal blood pressure. Twenty-five patients satisfied the metabolic syndrome diagnostic criteria. Hsp-90a concentrations were significantly higher (p = 0.002) in the individuals with arterial hypertension than in their normotensive counterparts (median ± interquartile range): 19.42 ng/mL ± 5.17 vs. 16.86 ng/mL ± 3.18. The concentrations of Hsp-90a correlated positively with systolic blood pressure (R = 0.39; p = 0.005) and diastolic blood pressure (R = 0.29; p = 0.046). CONCLUSIONS An increase in Hsp-90a concentrations in patients with arterial hypertension may be a compensatory mechanism for the impaired bioavailability of nitric oxide. The role of Hsp-90a as an early marker of hypertension-associated endothelial injury should be confirmed in further studies on a larger group of patients.

Abstract
The small peptides representation of the original proteins are a valuable source of information that can be used as biomarkers involved in toxicity mechanism for chemical exposure. The aim of this study is to investigate serum peptide biomarkers of benzene exposure. C57BL/6 mice were enrolled into control group and benzene groups of 150 and 300 mg/kg/d Serum peptides were identified by mass spectrometry using an assisted laser desorption ionization/time of flight mass spectrometry (MS). Differential peptide spectra were obtained by tandem mass spectrometry and analyzed by searching the International Protein Index using the Sequest program. Forty-one peptide peaks were found in the range of 1000-10,000 Da molecular weight. Among them, seven peaks showed significantly different expression between exposure groups and control group. Two peptide peaks (1231.2 and 1241.8), which showed a two-fold increase in expression, were sequenced and confirmed as glucose 6-phosphate dehydrogenase (G6PD) and heat shock protein 90 Beta (HSP90 Beta), respectively. Furthermore, the expression of the two proteins in liver cells showed the same trend as in serum. In conclusion, G6PD and HSP90 beta might be the candidate serum biomarkers of benzene exposure. It also provided possible clues for the molecular mechanism of benzene-induced oxidative stress.

Abstract
Current monitoring of acute lymphoblastic leukemia (ALL) in living mice is based on FACS analysis of blood hCD45+ cells. In this work, we evaluated the use of human IGFBP2, B2M or Hsp90 as soluble markers of leukemia. ELISA for B2M and IGFBP2 resulted in high background levels in healthy animals, precluding its use. Conversely, plasma levels of Hsp90 showed low background and linear correlation to FACS results. In another experiment, we compared Hsp90 levels with percentage of hCD45+ cells in blood, bone marrow, liver and spleen of animals weekly sacrificed. Hsp90 levels proved to be a superior method for the earlier detection of ALL engraftment and correlated linearly to ALL burden and progression in all compartments, even at minimal residual disease levels. Importantly, the Hsp90/hCD45+ ratio was not altered when animals were treated with dexamethasone or a PI3K inhibitor, indicating that chemotherapy does not directly interfere with leukemia production of Hsp90. In conclusion, plasma Hsp90 was validated as a soluble biomarker of ALL, useful for earlier detection of leukemia engraftment, monitoring leukemia kinetics at residual disease levels, and pre-clinical or mouse avatar evaluations of anti-leukemic drugs.

Abstract
This study was purposed to investigate the expression of heat shock protein 90 (HSP90) in peripheral blood plasma of patients with multipl myeloma (MM), and to explore its possible role in the pathogenesis of MM, and its relationship with treatment, prognosis and the outcome of patients. The peripheral blood samples from 58 patients with MM and 20 healthy volunteers were collected. The plasma concentration of HSP90 in patients and healthy volunteers was measured by ELISA. The results showed that the concentration of HSP90 in peripheral blood of patients with MM was significantly higher than that in the healthy volunteers [(32.398 ± 3.674) vs (25.762 ± 2.916) ng/ml] (P < 0.001). The concentration of HSP90 showed positively correlation with International Staging System(ISS) stage, therapeutic response, frequency of plasmocyte, globulin, immune globulin, M-protein, β2 micro-globulin, and light chain of MM patients (P < 0.05) ; while it showed little correlation with sex, age and type of MM patients (P > 0.05) . It is concluded that the HSP90 may be involved in the occurrence and development of MM. Detection of HSP90 in plasma would contribute to judge the clinical course, therapeutic efficacy and prognosis of MM patients.

Abstract
Ischemic stroke is the second leading cause of death worldwide. One of the main risk factors of the ischemic stroke is atherosclerosis which is a chronic inflammatory and immune-mediated disease. Bacterial infections generate specific human antibodies against various antigens, including Hsps. It has been demonstrated that Hsps are selectively overexpressed in the atherosclerotic lesions. The amino acid sequence homology between human and bacterial Hsps may lead to an autoimmune response by immunological cross-reaction. Such immune response against Hsps overexpressed in the blood vessels under stressful conditions may contribute to inflammatory processes and subsequent development of atherosclerosis. In this study we determined the antibody levels against bacterial and human Hsp by ELISA in blood plasma obtained from stroke patients. Using ANOVA we analyzed levels of Hsp-antibodies in control and patient groups and correlate them with several stroke risk factors. The group of stroke patients had elevated levels of anti-Hsp antibodies compared to the control group. We also discovered an antibody level increase in patients that previously underwent another stroke. Our data provide evidence that autoimmunity could underlie formation of atherosclerosis plaque leading to stroke.

Abstract
To explore the expression and clinical significance of molecular chaperone heat shock protein 90 (HSP90) in peripheral blood mononuclear cells (PBMC) and plasma level of interleukin-6 (IL-6) in patients with systemic lupus erythematosus (SLE), HSP90 was detected in PBMC by Western blot assay and the plasma level of IL-6 was measured by ELISA in 38 SLE patients and 20 normal controls. The correlation analysis was performed between the SLE disease activity index (SLE-DAI) and the expression of HSP90 and IL-6. The results showed that there was increased expression of HSP90 in the SLE patients. The active SLE group exhibited higher HSP90 levels (0.82+/-0.10) than the inactive SLE group (0.54+/-0.09) (P<0.01). The expression of HSP90 in normal control group (0.37+/-0.11) showed significant statistical difference as compared to both the inactive and active SLE groups (P<0.01, P<0.01, respectively). The plasma level of IL-6 exhibited a significant increase in both the inactive and active SLE groups (28.99+/-1.74 pg/mL, 44.58+/-9.15 pg/mL, respectively) compared with normal control group (P<0.01, P<0.01, respectively). The expression of HSP90 and IL-6 in SLE patients showed significant positive correlation with SLEDAI scoring (r=0.80, P<0.01: r= 0.74, P<0.01, respectively). In addition, there was a positive correlation between the level of IL-6 and HSP90 in SLE patients (r=0.86, P<0.01). The increased expression of molecular chaperone HSP90 and IL-6 may play an important role in the pathogenesis of SLE by regulating autoimmunity.

Abstract
The cell stress chaperone heat shock protein 90 (Hsp90) has been implicated in inflammatory responses and its inhibition has proven successful in different mouse models of autoimmune diseases, including epidermolysis bullosa acquisita. Here, we investigated expression levels and secretory responses of Hsp90 in patients with bullous pemphigoid (BP), the most common subepidermal autoimmune blistering skin disease. In comparison to healthy controls, the following observations were made: (i) Hsp90 was highly expressed in the skin of BP patients, whereas its serum levels were decreased and inversely associated with IgG autoantibody levels against the NC16A immunodominant region of the BP180 autoantigen, (ii) in contrast, neither aberrant levels of circulating Hsp90 nor any correlation of this protein with serum autoantibodies was found in a control cohort of autoimmune bullous disease patients with pemphigus vulgaris, (iii) Hsp90 was highly expressed in and restrictedly released from peripheral blood mononuclear cells of BP patients, and (iv) Hsp90 was potently induced in and restrictedly secreted from human keratinocyte (HaCaT) cells by BP serum and isolated anti-BP180 NC16A IgG autoantibodies, respectively. Our results reveal an upregulated Hsp90 expression at the site of inflammation and an autoantibody-mediated dysregulation of the intracellular and extracellular distribution of this chaperone in BP patients. These findings suggest that Hsp90 may play a pathophysiological role and represent a novel potential treatment target in BP.

Abstract
Early identification for heart failure (HF) may be useful for disease modifying treatment in order to reduce heart disease progression or even to reverse it. In our previous studies, we have revealed a group of heat shock proteins (HSPs) which might be related to neonatal rat cardiomyocyte hypertrophy by proteomic approach. Here, we confirm that HSPs, including HSP27 and HSP70, altered in the early stage of cardiac remodeling in vivo animal model. Furthermore, plasma concentrations of those HSPs and their potential screening value were evaluated at different stages in 222 patient subjects. Plasma HSP27, HSP70 and HSP90 were measured using enzyme-linked immunosorbent assay. Results indicate that HSP70 was positively correlated to the severity (progression) of HF (r = 0.456, p<0.001). The area under the rate of change (ROC) curve was 0.601 (p = 0.017) in patients with stage B HF and 0.835 (p<0.001) in those with stage C HF. However, HSP27 and HSP90 did not display significant changes in any stage of HF in this study. Taken together, plasma concentrations of HSP70 elevated with the progression of HF and might act as a potential screening biomarker for early diagnosis of HF.

Abstract
Heat shock protein (HSP) 70 and HSP90 are released by primary human acute myeloid leukemia (AML) cells during stress-induced spontaneous in vitro apoptosis. The AML cells also show constitutive release of several cytokines and the systemic serum levels of several soluble mediators are altered in patients with untreated AML. In the present study, we have investigated serum levels of HSP70/HSP90 and the serum cytokine profiles of patients with untreated AML and patients receiving AML-stabilizing palliative treatment based on all-trans retinoic acid (ATRA) plus valproic acid. Patients with untreated AML showed increased HSP90 levels and a distinct serum cytokine profile when compared with healthy controls, and low pre-therapy HSP90 levels were associated with a prolonged survival during treatment with ATRA + valproic acid + theophyllin. Hierarchical cluster analysis showed a close association between HSP70, HSP90, IL-1 receptor antagonist (IL-1ra), and hepatocyte growth factor (HGF) levels. Furthermore, disease-stabilizing therapy altered the serum-cytokine profile, but the correlations between HSP70/HSP90/IL-1ra/HGF were maintained only when ATRA + valproic acid were combined with theophyllin but not when combined with cytarabine. We conclude that both HSP levels and serum cytokine profiles are altered and may represent possible therapeutic targets or prognostic markers in human AML.

Abstract
BACKGROUND Heat-shock protein 90 (HSP90) is an abundant protein in mammalian cells. It interacts with a variety of proteins that play key roles in breast neoplasia. This is the first study to assess serum levels of HSP90 in atypical ductal hyperplasia (ADH), lobular neoplasia (LN), ductal carcinoma in situ (DCIS), invasive ductal carcinoma (IDC) and infiltrative lobular carcinoma (ILC). PATIENTS AND METHODS Serum concentrations of HSP90 in women with benign (n=34), ADH (n=26), DCIS (n=30), IDC (n=29), LN (n=20) and ILC (n=9) lesions were determined with immunoenzymatic assays. For the evaluation of serum concentrations along the transition from benign through precursor and preinvasive to invasive lesion, the severity of diagnosis was treated as an ordinal variable. RESULTS No significant association was demonstrated between serum HSP90 levels and the severity of the lesion in ductal and lobular series. The post hoc comparison between the lobular and ductal precursor lesions (i.e. ADH vs. LN) did not yield a statistically significant difference. Similarly, the post hoc comparison between the lobular and ductal invasive carcinomas (i.e. IDC vs. ILC) did not point to a statistically significant difference. CONCLUSION This is the first study evaluating HSP90 serum levels in both lobular and ductal lesions of the breast. Contrary to published pathological findings according to which HSP90 exhibits significant variability along both series, such a finding was not replicated for the level of serum HSP90 concentrations.

The system of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) may play a key role in atherogenesis of chronic kidney disease (CKD) patients by its impact on matrix accumulation. Connections with inflammation, stress, or endothelial dysfunction are also probable. However, the data on correlations between these parameters in CKD patients are scarce in adults and absent in children. The aim of our study was to evaluate serum concentrations of MMP-2, MMP-9, TIMP-1, and TIMP-2, as well as their correlations with markers of stress response (Hsp90-α, anti-Hsp60), endothelial dysfunction (sE-selectin), and inflammation (high-sensitivity C-reactive protein) in CKD children treated conservatively. Thirty-seven patients were divided into two groups according to the CKD stage (gr.CKDI, 19 children with CKD stages 2-3; gr.CKDII, 18 subjects with CKD stages 4-5). Twenty-four age-matched healthy subjects served as controls. Serum concentrations of MMP-2, MMP-9, TIMP-1, TIMP-2, Hsp90-α, anti-Hsp60, and sE-selectin were assessed by ELISA. Median values of MMP-2, MMP-9, TIMP-1, and TIMP-2 were significantly higher in all CKD children vs. controls and were increased in patients with CKD stages 4-5 vs. CKD stages 2-3. Hsp90-α, anti-Hsp60, sE-selectin, and glomerular filtration rate predicted the values of MMPs and TIMPs. Chronic kidney disease in children is characterized by MMP/TIMP system dysfunction, aggravated by the progression of renal failure. Correlations between examined parameters, heat shock proteins, and markers of endothelial damage suggest the possibility of MMP/TIMP application as indicators of stress response and atherogenesis in children with CKD on conservative treatment.

Abstract
Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death. Although the underlying pathomechanism remains poorly understood, COPD is accompanied by increased cellular stress and inflammation. We investigated serum contents of heat shock proteins (HSP 27, 60, 70, 90 alpha), 20S proteasomes, C-reactive protein (CRP), and interleukin-6 (IL-6) in patients with mild or severe COPD, healthy smokers and nonsmokers. HSP27, HSP70 and HSP90 alpha were significantly altered in patients suffering from COPD as compared to controls. HSP27 and HSP70 are potential novel serum markers for the diagnosis of COPD in the smoking population. This is the first study to demonstrate elevated serum levels of the described heat shock proteins in patients with COPD. We showed sensitivity and specificity of serum HSP27 and HSP70 as diagnostic markers for COPD.

Abstract
OBJECTIVE To explore the relationship between the expression of heat shock protein 90, 60 and 27 (HSP90, HSP60 and HSP27) and genetic damage in peripheral blood of workers exposed to coke oven emissions. METHODS 288 coke oven workers in a steel factory were divided into the high-dose group and the low-dose group on the basis of environment monitoring result and work place. There were 172 men in high-dose group (workers who worked at the oven top and oven side) and 116 men in low-dose group (workers who worked at the oven bottom and others who were engaged to aided work). 38 workers unexposed occupationally to carcinogenic substances were selected as the control group, who were employed in medical therapy unit nearby 2 kilometers from the steel factory. Their general information, history of personal and occupational exposure, and the work environment were investigated. Blood samples were collected immediately after a shift at the end of a working day from 288 coke oven workers and 38 control workers. Levels of HSP90, HSP60 and HSP27 in peripheral blood lymphocytes were measured by Western blot, and the degree of DNA damage was detected by the comet assay. RESULTS Levels of HSP90 in peripheral blood lymphocytes in three groups were 0.24 +/- 0.32, 0.12 +/- 0.30 and 0.06 +/- 0.33 respectively. They increased significantly compared with that of the control. But levels of HSP60 and HSP27 were not significantly different among those groups. Compared with the control group, there was significant difference in tail length, olive tail moment et al of SCGE (G +/- s(G)) of occupational exposure workers. High-dose group > low-dose group > control group (P < 0.05). The degree of DNA damage increased with the rise of exposure BaP dose (Spearman r = -0.345, P < 0.01). CONCLUSION Levels of HSP90 in peripheral blood lymphocytes and the degree of DNA damage increase with the rise of exposure polycyclic aromatic hydrocarbons (PAHs) dose.

Abstract
OBJECTIVES The study was undertaken to examine antioxidant status and level of the major intracellular heat shock proteins (Hsps) in healthy children and children with mild and moderate asthma. DESIGN AND METHODS Native gel assays were performed to estimate activities of copper/zinc (CuZn) and manganese (Mn) superoxide dismutase (SOD), and catalase (CAT) in peripheral blood mononuclear cells (PBMC) of healthy and asthmatic children. Hsp70 and Hsp90 protein levels in PBMCs were assessed by Western blot analysis. RESULTS Moderate asthmatics displayed higher CuZnSOD/CAT activity ratio compared to healthy children, and increased Hsp90 level compared to mild asthmatics and healthy children. CONCLUSIONS With regard to the imbalance in the antioxidant enzyme activities children with moderate asthma differ from healthy children, while an increased Hsp90 expression could be associated with the disease severity, as well.

Abstract
PURPOSE 17-(Allylamino)-17-demethoxygeldanamycin (17AAG), a benzoquinone antibiotic, down-regulates oncoproteins by binding specifically to heat shock protein 90 (HSP90). We did a phase I study of 17AAG to establish the dose-limiting toxicity and maximum tolerated dose and to characterize 17AAG pharmacokinetics and pharmacodynamics. EXPERIMENTAL DESIGN Escalating doses of 17AAG were given i.v. over 1 or 2 hours on a weekly x 3 schedule every 4 weeks to cohorts of three to six patients. Plasma pharmacokinetics of 17AAG and 17-(amino)-17-demethoxygeldanamycin (17AG) were assessed by high-performance liquid chromatography. Expression of HSP70 and HSP90 in peripheral blood mononuclear cells was measured by Western blot. RESULTS Forty-five patients were enrolled to 11 dose levels between 10 and 395 mg/m2. The maximum tolerated dose was 295 mg/m2. Dose-limiting toxicity occurred in both patients (grade 3 pancreatitis and grade 3 fatigue) treated with 395 mg/m2. Common drug-related toxicities (grade 1 and 2) were fatigue, anorexia, diarrhea, nausea, and vomiting. Reversible elevations of liver enzymes occurred in 29.5% of patients. Hematologic toxicity was minimal. No objective responses were observed. 17AAG pharmacokinetics was linear. Peak plasma concentration and area under the curve of 17AG, the active major metabolite of 17AAG, increased with 17AAG dose, but the relationships were more variable than with 17AAG. 17AAG and 17AG in plasma were >90% protein bound. There were no consistent changes in peripheral blood mononuclear cell HSP90 or HSP70 content. CONCLUSIONS 17AAG doses between 10 and 295 mg/m2 are well tolerated. 17AAG pharmacokinetics is linear. Peripheral blood mononuclear cell HSP90 and HSP70 are uninformative pharmacodynamic markers. The dose recommended for future studies is 295 mg/m2 weekly x 3, repeated every 4 weeks.

Abstract
OBJECTIVE To study the role of heat shock protein 90 (HSP 90) in the formation of hyperdynamic circulation of portal hypertensive rats. METHODS Animal model of portal hypertension was established by partial ligation of the portal vein among 20 SD rats (group P). Ten rats underwent sham operation (group S) Four weeks after the operation, the rats were killed and their mesenteric arteries and portal veins were obtained. The expression of HSP 90 in the portal veins and part of the superior mesenteric arteries was detected by Western blotting. Another mesenteric arteries underwent continuous perfusion with methoxamine (MTX, 30 and 100 micro mol/L) or acetylcholine (Ach). The perfusion pressure was monitored by a sensor. The concentration-response curves were examined in response to MTX and Ach infusion respectively. Then geldanamycin (GA) was infused; responses to MTX and ACh were repeated as described above. The endothelia of these arteries was denuded. After endothelial denudation was achieved, response to sodium nitroprusside (SNP) was examined. RESULTS The expression of HSP 90 was much stronger in the group P than in the group S. The perfusion pressure of the mesenteric artery of the group P was 13.32 mm Hg +/- 0.55 mm Hg, significantly lower than that of the group S (17.33 mm Hg +/- 0.57 mm Hg, n = 10, P < 0.001). After the addition of MTX, the perfusion pressure of the mesenteric artery of the group P was 141.9 mm Hg +/- 7.6 mm Hg, significantly lower than that of the group S (181.1 mm Hg +/- 16.2 mm Hg, n = 8, P < 0.001). GA and 30 micro mol/L or 100 micro mol/L MTX were added successively into the perfusion fluid for the mesenteric superior artery of the group P, then the perfusion pressure became 106.7 mm Hg +/- 7.5 mm Hg or 124.9 mm Hg +/- 5.5 mm Hg, significantly higher than those of the mesenteric superior artery of the group P without addition of GA (60.9 mm Hg +/- 4.3 mm Hg, n = 5, P < 0.05 and 98.7 mm Hg +/- 4.7 mm Hg, n = 5, P < 0.05). GA and 100 micro mol/L MTX were added successively into the perfusion fluid for the mesenteric superior artery of the group S, the perfusion pressure became 151.2 mm Hg +/- 7.1 mm Hg, not significantly different from that of the mesenteric superior artery of the group S without addition of GA (149.8 mm Hg +/- 5.6 mm Hg, P > 0.05). With the addition of GA in advance, the ACh-dependent vasorelaxation of the isolated perfused rat mesenteric artery was significantly attenuated in comparison with the mesenteric artery without addition of GA into whose perfusion fluid (P < 0.05). However, GA did not affect the vasodilation of the ensothelium-neduded mesenteric artery in response to SNP. CONCLUSION HSP90 is responsible for the hyperdynamic circulation in the portal hypertensive rats.

Abstract
A minimal system of five proteins, hsp90, hsp70, Hop, hsp40, and p23, assembles glucocorticoid receptor (GR).hsp90 heterocomplexes and causes the simultaneous opening of the steroid binding cleft to access by steroid. The first step in assembly is the ATP-dependent and hsp40 (YDJ-1)-dependent formation of a GR.hsp70 complex that primes the receptor for subsequent ATP-dependent activation by hsp90, Hop, and p23. This study focuses on three aspects of the GR priming reaction with hsp70. First, we have visualized the primed GR.hsp70 complexes by atomic force microscopy, and we find the most common stoichiometry to be 1:1, with some complexes of a size approximately 1:2 and a few complexes of larger size. Second, in a recent study of progesterone receptor priming, it was shown that hsp40 binds first, leading to the notion that it targets hsp70 to the receptor. We show here that hsp40 does not perform such a targeting function in priming the GR. Third, we focus on a short amino-terminal segment of the ligand binding domain that is required for GR.hsp90 heterocomplex assembly. By using two glutathione S-transferase (GST)/ligand binding domain fusions with (GST/520C) and without (GST/554C) hsp90 binding and steroid binding activity, we show that the priming step with hsp70 occurs with GST/554C, and it is the subsequent assembly step with hsp90 that is defective.

Abstract
Serological screening of recombinant cDNA expression libraries has been widely used for the identification of tumour antigens in various cancer types. Identification of tumour antigens in ovarian cancer may facilitate the development of vaccine-based therapies and of disease biomarkers. The purpose of our investigation is to identify tumour antigens in ovarian cancer by using the serological analysis of recombinant cDNA expression libraries method. A recombinant ovarian carcinoma cDNA expression library was screened with ascites fluid, pooled from five ovarian cancer patients. Twelve tumour antigens encoded by known genes were isolated, including ribosomal protein S18, heat shock protein 90, JK-recombination signal binding protein, ribonucleoprotein H1, RAN binding protein 7, TG-interacting factor, eukaryotic translation initiation factor p40 subunit, human amyloid precursor protein-binding protein 1, ribosomal protein L8, CDC23, IQ motif containing GTPase activating protein 1, and ribosomal protein L3. Heat shock protein 90 was chosen for further investigation. The prevalence of hsp90 autoantibodies in ovarian cancer was determined with immunoassay. Sera from 22 normal females, 32 from ovarian cancer (22 stage III/IV, 10 stage I/II), 37 colorectal cancer, 13 breast cancer, 10 lung cancer, 20 benign gynaecologic diseases, and 10 benign breast lesions were screened. Seven (32%) stage III/IV ovarian cancer, 1 (10%) stage I/II ovarian cancer, 1 (3%) colorectal cancer, 1 (8%) breast cancer, and 1 (5%) benign gynaecologic disease sera were found to contain hsp90 autoantibodies. These data support the view that hsp90 autoantibodies are frequently found in late stage ovarian cancer. Hsp90 may, therefore, represent a novel biomarker for ovarian cancer and a candidate ovarian cancer vaccine target.

Abstract
Levels of the 90 kDa heat shock protein (hsp90) are elevated in a subset of patients with systemic lupus erythematosus (SLE) due to enhanced transcription of the hsp90beta gene. In cultured cells, transcription of the hsp90beta gene is induced following exposure to IL-6 or IL-10 which are known to be elevated in SLE patients. Here we have measured the levels of hsp90 protein and of IL-6, IL-10 in SLE patients and normal controls. We demonstrate that the levels of hsp90 protein in individual patients correlate with the IL-6 level but not with the level of IL-10. Moreover, hsp90 protein levels in patients correlate with the presence of IgG autoantibodies to hsp90. These results support a model in which elevated levels of IL-6 in SLE patients induce elevated levels of hsp90 protein which in turn results in the production of autoantibodies to this protein.

Abstract
Peripheral blood mononuclear cells (PBMC) were challenged with different concentrations of mercuric chloride and the expression of heat shock protein (hsp) 65, 72 and 90, were investigated by an indirect peroxidase method as well as the proliferation was measured by uptake of tritiated thymidine into DNA. Hsp 65 immunoreactivity was peripherally located in the cells at a mercuric chloride concentration of 5.5-2.8x10(-5) mol/L, which also gave a decreased DNA synthesis. Hsp 72 positive cells, with a nuclear and cytoplasmic immunoreactivity, were found at a concentration of 5.5-2.2x10(-5) mol/L. Hsp 90 positive cells also with an immunoreactivity at a nuclear and cytoplasmic level, were found at 1.1x10(-5)-5.5x10(-6) mol/L. A stimulated DNA synthesis was obtained already at 2.2x10(-5) mol/L and was found down to 5.5x10(-6) mol/L. High concentrations of mercuric chloride might induce expression of hsp 65 and 72 as a protective mechanism. Hsp 90 as well as hsp 72 might be involved in the proliferation of human PBMC to mercuric chloride. Thus, this expression of hsp 72 may have a dual role.

Abstract
Peripheral leukocyte heat shock proteins (HSP: HSP90, HSP70, and HSP23) from broiler chickens and turkey poults were induced by in vitro and in vivo high temperature exposure. Heat conditioning, via a daily 1 h exposure to 41 C, enhanced in vitro HSP expression in leukocytes from chickens heat-conditioned for 1 to 2 wk, and a similar response was found in turkey poults with 3 wk of heat conditioning causing the greatest HSP expression. In vivo heat exposure trials caused maximization of HSP expression after 1 wk of daily heat conditioning exposures in broilers, but no additional enhancement was seen in chickens heat conditioned for 2 wk. Enhancement in HSP expression was evident for periods up to 4 wk after termination of the daily heat conditioning episodes.

Abstract
Expression of heat-shock proteins (hsp) was analysed in the leukaemic cells of 12 patients with acute myeloid leukaemia (AML) and nine patients with chronic myeloid leukaemia (CML). Using monoclonal antibodies to hsp70, hsp90 and hsp60 (ML30, a mycobacterial antigen with homology to human hsp60), we measured hsp levels by flow cytometry of permeabilized cells. Mononuclear cells from 10 healthy volunteers were also examined. The results demonstrate that hsp expression is significantly increased (P < 0.01) in the circulating cells of patients with AML compared with cells from CML patients, and compared with normal peripheral blood mononuclear cells. This increased pattern of expression was found for all three heat-shock protein families included in this study. Mononuclear cells from leukaemic patients showed a heterogenous pattern of hsp expression, between different patients, between cells from individual patients, and between the different hsp proteins examined. It is possible that hsp expression relates to the differentiation state or proliferative potential of these leukaemic cells.
