Abstract
AIMS The aim of this study was to compare the efficacy and safety of induction therapy using the interleukin-2 receptor antagonist (IL-2RA) with antithymocyte globulin (ATG) under a tacrolimus-based immunosuppression regimen in kidney transplantation from donors after cardiac death. METHODS It was a single-centre, retrospective, cohort study design to evaluate the efficacy and safety of IL-2RA vs. ATG induction therapy in adult renal transplant recipients from donors after cardiac death. The primary end-point was the incidence of biopsy-proven acute rejection (BPAR) at 6 months, and the secondary end-point included the incidence of delayed graft function (DGF), the renal function, and the patient and graft survival at 6 months. The safety end-point was the incidence of infectious complications. RESULTS A total of 132 patients (n = 37 in the IL-2RA group and n = 95 in the ATG group) were enrolled from March 2013 to April 2014. The BPAR at 6 months was similar between the two groups (IL-2RA vs. the ATG group, 5.4% vs. 12.6%, respectively, p = 0.228). There were no differences in the DGF, renal function at 1 and 3 months, and the patient and graft survival at 6 months between the two groups, but the renal function at 6 months in the IL-2RA group was superior to that of the ATG group (p = 0.02). The IL-2RA group experienced less infection than the ATG group (p = 0.025). CONCLUSIONS The efficacy of IL2-RA and ATG induction under a tacrolimus-based immunosuppression regimen in low-risk DCD transplantation did not differ, but the safety of the IL2-RA induction was better than that of the ATG induction.

Abstract
OBJECTIVE We conducted a meta-analysis to quantitatively evaluate the correlation between pesticide exposure and the risk of bladder cancer by summarizing the results of published case-control and cohort studies. METHODS A systematic literature search of articles update to February 2015 was conducted via Pubmed, Web of Science, Cochrane Library, and the Chinese National Knowledge Infrastructure (CNKI) databases, and the references of the retrieved articles. Fixed- or random-effect models were used to summarize the estimates of OR with 95% CIs for the highest versus the lowest exposure of pesticide. RESULTS The pooled OR estimates indicated that pesticide exposure was associated with an increased risk of bladder cancer (OR=1.649, 95% CI 1.223-2.223). In subgroup analysis, we detected pesticide exposure demonstrated as a significant risk factor on bladder cancer in America (OR=1.741, 95% CI 1.270-2.388). Similar results were discovered in both case-control group and cohort group (OR=2.075, 95% CI 1.183-3.638, OR=1.146, 95% CI 1.074-1.223, respectively). No evidence of publication bias was found by Begg's or Egger's test (P = 0.210, P = 0.358, respectively). CONCLUSION In conclusion, our meta-analysis indicated that pesticide exposure was associated with an increased risk of bladder cancer. Further researches should be conducted to confirm the findings in our study and better clarify the potential biological mechanisms.

Is magnetic resonance/ultrasound fusion prostate biopsy better than systematic prostate biopsy? An updated meta- and trial sequential analysis. Oncotarget 2016; 6:43571-80. [PMID: 26498362 PMCID: PMC4791251 DOI: 10.18632/oncotarget.6201] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2015] [Accepted: 10/11/2015] [Indexed: 02/05/2023] Open
Abstract
We systematically reviewed the literature to determine whether Magnetic Resonance/Ultrasound (MR/US) fusion prostate biopsy is better than systematic biopsy for making a definitive diagnosis of prostate cancer. The two strategies were also compared for their ability to detect lesions with different degrees of suspicion on MRI and clinically significant prostate cancer, and the number of cores needed for diagnosis. The Cochrane Library, Embase, Web of Knowledge, and Medline were searched from inception until May 1, 2015. Meta-analysis was conducted via RevMan 5.2 software. Data was expressed as risk ratio (RR) and 95% confidence interval. Trial sequential analysis was used to assess risk of random errors. Fourteen trials were included, encompassing a total of 3105 participants. We found that MR/US fusion biopsy detected more prostate cancers than systematic biopsy (46.9% vs. 44.2%, p=0.03). In men with moderate/high MRI suspicion, MR/US fusion biopsy did better than systematic biopsy (RR = 1.46; p < 0.05) for making a diagnosis. Moreover, MR/US fusion biopsy detected more clinically significant cancers than systematic biopsy (RR = 1.19; p < 0.05). We recommend that MR/US fusion prostate biopsy be used to better detect prostate cancer, particularly in patients with moderate/high suspicion lesions on MRI.

Abstract
To date, only 20 cases of Epstein-Barr virus (EBV)-associated intrahepatic cholangiocarcinomas (IHCCs) have been reported in the literature.Pathology records of IHCC from January 1, 2007 to December 31, 2013 were retrieved from our hospital. Clinical information related to EBV-associated IHCC were also obtained, including gender, age at initial diagnosis, tumor size, tumor-node-metastasis stage, and follow-up duration. Surgically resected stage-matched EBV-negative IHCCs with full follow-up were selected for comparison. All liver specimens were fixed in 10% neutral-buffered formalin and paraffin-embedded tissue blocks containing cholangiocarcinoma and nonneoplastic liver tissue. Hematoxylin and eosin-stained sections were present in all cases.Among 329 primary IHCC patients, intranuclear expression of EBV was only found in 11 patients (3.3%), with an age range of 30 to 67 years (mean, 53.2 years; median, 54 years). The group consisted of 4 male and 7 female patients (M:F ratio 1:1.8). Histopathological analysis showed 1 case (9.1%) belonged to the typical lymphoepithelioma-like carcinoma (LELC), primarily composed of undifferentiated tumor cells intimately admixed with abundant lymphoplasmacytic cells. Two cases (18.2%) belonged to the conventional-type IHCCs, showing irregularly shaped neoplastic glands and scattered lymphoplasmacytic infiltration. The remaining 8 cases (72.7%) belonged to the lymphoepithelioma-like cholangiocarcinomas (LELCCs), showing varied glandular differentiation and dense lymphoplasmacytic infiltration. The overall survival of EBV-positive IHCCs was not significantly different from that of EBV-negative IHCCs (P = 0.512).Our data demonstrate that EBV-associated IHCC is very rare and may be subclassified into 3 different pathological types including LELC, conventional-type IHCC and LELCC on the basis of the tumor cellular differentiation, and host cellular immune responses in the tumors. The etiological, clinical, pathological, and molecular features are needed to be future studied by multicentric efforts in recruiting more EBV-associated IHCC patients.

Expression and Critical Role of Interleukin Enhancer Binding Factor 2 in Hepatocellular Carcinoma. Int J Mol Sci 2016; 17:ijms17081373. [PMID: 27556459 PMCID: PMC5000768 DOI: 10.3390/ijms17081373] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2016] [Revised: 08/05/2016] [Accepted: 08/08/2016] [Indexed: 02/05/2023] Open
Abstract
Interleukin enhancer binding factor 2 (ILF2), a transcription factor, regulates cell growth by inhibiting the stabilization of mRNA. Currently, its role has gained recognition as a factor in the tumorigenic process. However, until now, little has been known about the detailed role ILF2 plays in hepatocellular carcinoma (HCC). In this study, we investigated the expression levels of ILF2 in HCC tissue with Western blot and immunohistochemical assays. To examine the effect of ILF2 on liver cancer cell growth and apoptosis, small interfering RNAs (siRNAs) targeting ILF2 were recombined to create lentiviral overexpression vectors. Our results showed higher expression levels of ILF2 mRNA and ILF2 protein in HCC tissue compared with matched peritumoral tissue. Expression of ILF2 may regulate cell growth and apoptosis in liver cancer cells via regulation of B-cell lymphoma 2 (Bcl-2), Bcl-2 related ovarian killer (Bok), Bcl-2-associated X protein (BAX), and cellular inhibitor of apoptosis 1 (cIAP1). Moreover, we inoculated nude mice with liver cancer cells to investigate the effect of ILF2 on tumorigenesis in vivo. As expected, a rapid growth was observed in cancer cells inoculated with a lentiviral vector coding Flag-ILF2 (Lenti-ILF2) compared with the control cells. Hence, these results promote a better understanding of ILF2’s potential role as a therapeutic target in HCC.

Abstract
The transcriptional coactivator with PDZ binding motif (TAZ) is reported as one of the nuclear effectors of Hippo-related pathways. TAZ is found overexpressed in many primary tumors and could regulate many biological processes. However, little is known about the role of TAZ in Intrahepatic Cholangiocarcinoma (ICC). In this study, we found that TAZ is expressed more in ICC tissues than in peritumoral tissue, and a robust expression of TAZ is correlated with a lower overall survival rate of ICC patients after hepatectomy. TAZ knockdown results in an increase in cell apoptosis, a promotion of cell-cycle arrest and a decrease in tumor size and weight in vivo through an increased expression of p53. Vitamin D3 can also inhibit cell proliferation by promoting p53 expression in ICC cells. A reduction in TAZ can also enhance the sensitivity of tumor cells to vitamin D by regulating the p53/CYP24A1 pathway. In conclusion, TAZ is associated with the proliferation and drug-resistance of ICC cells, and could be a novel therapeutic target for the treatment of ICC.

Abstract
A meta-analysis was conducted to quantitatively evaluate the correlation between night shift work and the risk of colorectal cancer. We searched for publications up to March 2015 using PubMed, Web of Science, Cochrane Library, EMBASE and the Chinese National Knowledge Infrastructure databases, and the references of the retrieved articles and relevant reviews were also checked. OR and 95% CI were used to assess the degree of the correlation between night shift work and risk of colorectal cancer via fixed- or random-effect models. A dose-response meta-analysis was performed as well. The pooled OR estimates of the included studies illustrated that night shift work was correlated with an increased risk of colorectal cancer (OR = 1.318, 95% CI 1.121-1.551). No evidence of publication bias was detected. In the dose-response analysis, the rate of colorectal cancer increased by 11% for every 5 years increased in night shift work (OR = 1.11, 95% CI 1.03-1.20). In conclusion, this meta-analysis indicated that night shift work was associated with an increased risk of colorectal cancer. Further researches should be conducted to confirm our findings and clarify the potential biological mechanisms.

Abstract
Peptidylprolyl isomerase A (PPIA) is a peptidyl-prolyl cis-trans isomerase that is known to play a critical role in the development of many human cancers. However, the precise biological function of PPIA in hepatocellular carcinoma (HCC) remains largely unclear. In this study, lentiviral overexpression vectors and small interfering RNA knockdown methods were employed to investigate the biological effects of PPIA in HCC. PPIA levels in HCC tissues and peritumoral tissues were detected by real-time Polymerase Chain Reaction (RT-PCR), Western blotting, and immunohistochemistry. Our results indicate that PPIA levels were significantly higher in the HCC tissues compared to the matched peritumoral tissues. Moreover, PPIA expression was significantly associated with tumor size in these tissues. Interestingly, serum PPIA (sPPIA) levels were significantly higher in healthy controls compared to the HCC patients. Knockdown or overexpression of PPIA was shown to downregulate and upregulate cell growth, respectively. Moreover, PPIA siRNA knockdown appears to promote doxorubicin-induced apoptosis in HCC cells, altering the expression of downstream apoptotic factors. In summary, our results indicate that PPIA may play a pivotal role in HCC by regulating cell growth and could serve as a novel marker and therapeutic molecular target for HCC patients.

Abstract
AIM The purpose of our study was to evaluate the incidence, timing, location and risk factors for bacterial and fungal infections after donation after cardiac death (DCD) liver transplant and clearly delineate any relationship between infection and survival in DCD liver transplant recipients. METHODS We retrospectively reviewed 257 consecutive patients undergoing DCD liver transplant between October 2010 and May 2015 at our centre. RESULTS A total of 133 patients (51.8%) developed at least one bacterial or fungal infection episode. The predominant infection site was the respiratory tract, followed by the blood stream. Most of the infections occurred within the first week after liver transplant (61.9%). A recipient respiratory support time greater than 7 days (p = 0.041), post-transplant hospital time greater than 24 days (p = 0.002) and renal failure after DCD liver transplant (p = 0.039) were independent predictors of bacterial and fungal infection. The area under the receiver operating characteristic (ROC) curve (AUC) of the transplant infection risk assessment model was 0.788. The 1- and 3-year survival rates for recipients without infection were significantly increased compared with recipients with infection (96.1% and 89.0% vs. 81.5% and 75.9%, p = 0.007). CONCLUSION This is the first study that offers detailed data revealing the timing and incidence of bacterial and fungal infection among adult DCD liver transplant recipients. Bacterial and fungal infection occurs at a high rate during the first week after DCD liver transplant, especially in patients with prolonged respiratory support time and renal failure, and infection is related to increased hospital stay.

Abstract
BACKGROUND The different outcomes of deceased donor liver transplantation (DDLT) and living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC) are currently being debated. We aimed to retrospectively compare the outcomes following LDLT and DDLT and to analyse the factors influencing this. METHODS We compared the overall survival (OS) and disease-free survival (DFS) rates of HCC patients after LDLT (n=389) and DDLT (n=6471) from 81 centres over a 10-year period. OS and DFS rates were calculated with the Kaplan-Meier method. And univariate and multivariate Cox proportional hazards regressions were performed on the entire cohort to identify predictors. RESULTS Of 6860 patients, the 1-, 3-, and 5-year OS rates were 86.79%, 70.16%, and 66.31% after LDLT, respectively, and 74.2%, 54.21%, and 46.97% after DDLT, respectively (P<0.001). The 1-, 3-, and 5-year DFS rates were 78.46%, 63.68%, and 61.63% after LDLT, respectively, and 65.65%, 48.61%, and 41.87% after DDLT, respectively (P<0.001). The multivariate Cox regression model determined that the DFS and OS of HCC patients post-liver transplantation (LT) were strongly associated with tumour morphology and biology, but not graft type. CONCLUSIONS With regards to OS and DFS, there were no disadvantages to LDLT as compared with DDLT; tumour morphology and biology may affect the prognosis of LT.

Abstract
OBJECTIVE Liver transplantation is an optimal radical therapy for selected patients with hepatocellular carcinoma. The stringent organ allocation system driven by the Milan criteria has been challenged by alternative sets of expanded criteria. Careful analysis is needed to prove that the Milan criteria can be expanded safely and effectively. DESIGN This study collectively reviewed 6012 patients of hepatocellular carcinoma from the China Liver Transplant Registry. Expanded criteria were evaluated to characterise an optimised expansion with acceptable outcomes beyond the Milan criteria. RESULTS Compared with the Milan criteria, Valencia, University of California, San Francisco, University Clinic of Navarra and Hangzhou criteria provided an expansion of 12.4%, 16.3%, 19.6%, and 51.5%, respectively. The post-transplant survivals of patients fulfilling the expanded criteria were comparable to that of the Milan criteria. The analysis of net reclassification improvement and area under the receiver operating characteristic curves showed an excellent efficiency in recurrence prediction for the expanded criteria compared with the Milan criteria. In patients exceeding Milan but fulfilling the Hangzhou criteria (N=1352), α-fetoprotein (AFP) >100 ng/mL and tumour burden>8 cm were the only two independent prognostic factors (p<0.001). Accordingly, the Hangzhou criteria were stratified as type A (tumour burden ≤8 cm, or tumour burden >8 cm but AFP≤100 ng/mL) and type B (tumour burden >8 cm but AFP between 100 and 400 ng/mL). Type A showed significantly higher 5-year tumour-free survival rates compared with type B (p<0.001). CONCLUSIONS The Milan criteria can be expanded safely and effectively. The prognostic stratification system based on the Hangzhou criteria serves as a hierarchy of transplant candidates for hepatocellular carcinoma.

Smaller grafts do not imply early recurrence in recipients transplanted for hepatocellular carcinoma: A Chinese experience. Sci Rep 2016; 6:26487.

Abstract
Liver graft size has long been a critical issue in adult-to-adult living donor liver transplantation (LDLT). We analyzed China Liver Transplant Registry data (January 2007–December 2009), identifying 295 patients who underwent LDLT for hepatocellular carcinoma (HCC). The recipients were divided into two groups: A, graft-to-recipient body weight ratio (GRWR) ≤ 0.8% (n = 56); B, GRWR > 0.8% (n = 239). We evaluated donor, recipient, and operative factors and analyzed survival outcome and the risk factors affecting overall and recurrence survival. As a result, the overall survival rates of group B were significantly higher than that of group A (p = 0.009); the corresponding tumor-free survival rates did not differ significantly (p = 0.133). The overall survival rates among the 151 recipients who met the Hangzhou criteria did not differ significantly (p = 0.953), nor did the corresponding tumor-free survival rates (p = 0.893). Multivariate analysis determined that GRWR was a significant risk factor for poor survival but not for early recurrence. In conclusion, small grafts may predict poorer survival outcome but do not indicate earlier HCC recurrence in recipients transplanted for HCC, and survival outcome with smaller grafts is merely acceptable in selected recipients.

Abstract
Background De novo malignancies occur after liver transplantation because of immunosuppression and improved long-term survival. But the spectrums and associated risk factors remain unclear. Aims To describe the overall pattern of de novo cancers in liver transplant recipients. Methods Data from Scientific Registry of Transplant Recipients from October 1987 to December 2009 were analyzed. The spectrum of de novo cancer was analyzed and logistic-regression was used to identify predictors of do novo malignancies. Results Among 89,036 liver transplant recipients, 6,834 recipients developed 9,717 post-transplant malignancies. We focused on non-skin malignancies. A total of 3,845 recipients suffered from 4,854 de novo non-skin malignancies, including 1,098 de novo hematological malignancies, 38 donor-related cases, and 3,718 de novo solid-organ malignancies. Liver transplant recipients had more than 11 times elevated cancer risk compared with the general population. The long-term overall survival was better for recipients without de novo cancer. Multivariate analysis indicated that HCV, alcoholic liver disease, autoimmune liver disease, nonalcoholic steatohepatitis, re-transplantation, combined transplantation, hepatocellular carcinoma, immunosuppression regime of cellcept, cyclosporine, sirolimus, steroids and tacrolimus were independent predictors for the development of solid malignancies after liver transplantation. Conclusions De novo cancer risk was elevated in liver transplant recipients. Multiple factors including age, gender, underlying liver disease and immunosuppression were associated with the development of de novo cancer. This is useful in guiding recipient selection as well as post-transplant surveillance and prevention.

Abstract
BACKGROUND/AIMS New-onset diabetes after transplantation (NODAT) is a serious complication of liver transplantation (LT). The present study aimed to investigate the risk factors of NODAT by a national survey using the China Liver Transplant Registry database. PATIENTS A total of 10 204 non-pre-existing diabetic patients undergone primary LT between January 2000 and December 2013 were included. Risk factors were identified by logistic regression analysis. RESULTS NODAT occurred in 24.3% of liver recipients with a median follow-up time of 2.6 years, and was associated with a significantly lower patient survival. NODAT increased not only diabetes related complications (e.g., infection, kidney failure) but also biliary stricture and cholangitis. NODAT patients who received hypoglycaemic treatment had a worse prognosis and a higher hepatocellular carcinoma recurrence compared with those without treatment. New-onset hyperglycaemia (<30 days) was the major predictor of NODAT. Other risk factors included cold ischaemia time >9 h, recipient age >50 years, body mass index >25 kg/m(2) , other hepatitis (mainly hepatitis C), post-transplant intensive care unit stay >15 days, cytomegalovirus infection and corticosteroid at discharge. CONCLUSIONS The incidence of NODAT in China is similar to that in Western countries. However, the NODAT-related complications are more common and severer in China compared with those in Western countries. The major risk factors are different.

Abstract
The aim of this study was to explore the association of Forkhead box O6 (FOXO6) expression with oxidative stress level and prognosis of hepatocellular cancer (HCC).The case group included tissues of HCC from 128 patients who were hospitalized in Division of Hepatobiliary and Pancreatic Surgery, Department of Surgery of First Affiliated Hospital, School of Medicine, Zhejiang University. The control group included normal liver tissues from 74 patients. RT-PCR and Western blot were used to test expressions of FOXO6, heme oxygenase (HO)-1, glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT). Dihydroethidium (DHE) was dyed to observe reactive oxygen species (ROS) level. Immunohistochemistry was used to test FOXO6 expression. FOXO6 was silenced in HepG2 cells to detect cell proliferation and apoptosis. The expressions of ROS, HO-1, GPx, SOD, CAT, p27, and cyclin D1 were also detected to further explore the possible mechanism.The expressions of FOXO6, HO-1, GPx, SOD, and CAT in HCC tissue was significantly higher than those in normal and adjacent HCC tissues (P <0.05). The tumor size, TNM stage, Alpha-fetoprotein (AFP) level, the presence or absence of hepatitis B surface antigen (HbsAg), and differentiation degree were related to FOXO6 expression level (all P <0.05). COX analysis showed that high FOXO6 expression, male, positive HBsAg, advanced TNM staging, high expression of AFP, and low degree of differentiation were all risk factors for prognosis in HCC (P <0.05). Compared with the blank group (C group, without transfection) and the negative control (NC) group, the mRNA expressions of ROS, FOXO6, HO-1, SOD, GPx, and CAT were decreased (P <0.05). si-RNA group had significantly decreased proliferation speed during 24 to 72 hours (P <0.05), whereas si-FOXO6 group had remarkably increased G0/G1 staged cells and decreased S-staged cells (P <0.05). The si-FOXO6 group showed notably increased apoptosis rate (P <0.05) and p27 expressions as well as decreased cyclin D1 expressions (P <0.05).FOXO6 was highly expressed in HCC tissue and was related to oxidative stress levels. Furthermore, FOXO6 expression can be used as a biomarker for deterioration and prognosis of liver cancer, which may provide a novel treatment target for HCC therapy.

Cell Death Dis 2016; 7:e2088.

Abstract
Emerging evidence has suggested that microRNAs (miRNAs) have an important role in tumor development and progression by regulating diverse cellular pathways. Here we describe the function and regulation network of miR-433 in bladder cancer (BCa). miR-433 is frequently downregulated in BCa tissues compared with adjacent non-cancerous tissues. Epigenetic mechanisms may be involved in the regulation of miR-433 expression. Enforced expression of miR-433 significantly inhibits proliferation, colony formation, migration, and invasion in BCa cells. In addition, miR-433 inhibits the epithelial–mesenchymal transition (EMT) in BCa cells by regulating c-Met/Akt/GSK-3β/Snail signaling pathway. Both c-Met and CREB1 are downstream target genes of miR-433. CREB1 can also indirectly regulate c-Met/Akt/GSK-3β/Snail signaling via MITF. Furthermore, CREB1 expression is an independent prognostic factor for overall survival in patients with BCa. Finally, there appears to exist a reciprocal regulation between c-Met and miR-433/miR-409-3p. Taken together, this study reveals that miR-433-c-MET/CREB1-Akt/GSK-3β/Snail signaling is critical to EMT in BCa. Targeting the pathway described here may open up new prospects to restrict metastatic progression of BCa.

γ-H2AX promotes hepatocellular carcinoma angiogenesis via EGFR/HIF-1α/VEGF pathways under hypoxic condition. Oncotarget 2015; 6:2180-92.

Abstract
Hepatocellular carcinoma (HCC) is one of the most deadly cancers. Using mRNA microarray analysis, we found that H2AX decreased under hypoxic conditions. Hypoxia is an important physiological and pathological stress that induces H2AX phosphorylation (γ-H2AX), but the regulatory mechanism of γ-H2AX remains elusive in the progress of HCC. We report here that increased γ-H2AX expression in HCC is associated with tumor size, vascular invasion, TNM stage and reduced survival rate after liver transplantation (LT). γ-H2AX knockdown was able to effectively inhibit VEGF expression in vitro and tumorigenicity and angiogenesis of HCC in vivo. The mechanism of γ-H2AX on the angiogenic activity of HCC might go through EGFR/HIF-1α/VEGF pathways under hypoxic conditions. Combined γ-H2AX, HIF-1α and EGFR has better prognostic value for HCC after LT. This study suggests that γ-H2AX is associated with angiogenesis of HCC and γ-H2AX or a combination of γ-H2AX/EGFR/HIF-1α is a novel marker in the prognosis of HCC after LT and a potential therapeutic target.

Abstract
AIMS Hsp27, a master molecular chaperone, plays an important role in cancer. However, the specific co-chaperones that partner with Hsp27 and the role of Hsp27 in hepatocellular carcinoma (HCC) are not fully enumerated. The present study focuses on the role of Hsp27 in HCC and explores its potential co-chaperones in HCC development. METHODS Gene overexpression or knockdown was used to observe the role of Hsp27 in HCC. Co-immunoprecipitation and mass spectrometry were used to explore apoptosis resistance by regulating multiple co-chaperones of Hsp27. Hsp27 protein-protein interaction (PPI) networks were constructed by the MetaCore software. RESULTS Hsp27 was upregulated in HCC tissues, and Hsp27 overexpression significantly facilitated formation of HCC cell colony and invasion in normoxia and tolerance in hypoxia by interacting with HIF-1α. Next, the analysis of microarrays revealed that Hsp27 regulated several cellular signaling pathways, including Wnt, ErbB and TGF-β signaling. Moreover, we characterized the Hsp27 PPI map, which indicated that Hsp27 along with its co-chaperones formed different complexes and exerts transcription regulation activity by activating sp1, c-Myc, p53 and ESR1. CONCLUSIONS Hsp27 along with its co-chaperones was related to the development of HCC by regulating multiple signaling pathways, and drugs that target Hsp27 along with its co-chaperones may be a potential therapy for HCC.
