Comparison of indocyanine green-near-infrared fluorescence guided and traditional mediastinal lymphadenectomy during radical esophagectomy: A randomized controlled trial. Surgery 2024; 175:347-352. [PMID: 38012899 DOI: 10.1016/j.surg.2023.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 09/02/2023] [Accepted: 10/24/2023] [Indexed: 11/29/2023]
Abstract
BACKGROUND The extent of lymph node dissection during radical esophagectomy remains a controversial topic. Thus, this study mainly aimed to explore the location of sentinel lymph nodes in esophageal squamous cell carcinoma and the application value of the indocyanine green-near-infrared fluorescence system in lymphadenectomy. METHODS This randomized controlled clinical trial (ClinicalTrials.gov, NCT04615806) included 42 participants without neoadjuvant therapy who were lymph node negative based on positron emission tomography/computed tomography findings. Traditional esophagectomy with indocyanine green-near-infrared fluorescence imaging was performed after injecting 0.5 mL indocyanine green (1.25 mg/mL) into the esophageal submucosa in the 4 peritumoral quadrants. The primary endpoint was to determine the location of the sentinel lymph node in esophageal squamous cell carcinoma based on postoperative pathologic reports. RESULTS A total of 40 patients, with 20 in each group, were included in the final analysis. In the indocyanine green group, indocyanine green-near-infrared fluorescence imaging was successful in all subjects. Seven cases (cases 2, 3, 9, 11, 17, 18, and 20) in the indocyanine green group exhibited lymph node metastases, all of which were near-infrared positive. The detection rate, positive predictive value, negative predictive value, sensitivity, and specificity were 100% (20 of 20 cases), 8.7% (13/150), 100% (265/265), 100% (13/13), and 65.9% (265/402), respectively. All near-infrared-negative lymph nodes were nonmetastatic lymph nodes. In addition, the number of mediastinal lymph nodes resected in the indocyanine green group was significantly higher than in the non-indocyanine green group. CONCLUSION Indocyanine green-near-infrared might be an important and promising technique in predicting sentinel lymph nodes of esophageal squamous cell carcinoma and could significantly improve the detection rate of lymph nodes of esophageal squamous cell carcinoma.

Clinical importance of serum and pleural fluid prominin-1 and hypoxia-inducible factor-1α concentration in the evaluation of lymph node involvement in patients with malignant pleural effusion. Biochem Med (Zagreb) 2023; 33:030701. [PMID: 37841777 PMCID: PMC10564156 DOI: 10.11613/bm.2023.030701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Accepted: 07/08/2023] [Indexed: 10/17/2023] Open
Abstract
Introduction Malignant pleural effusion (MPE) and lymph node metastasis (LNM) presence are poor prognostic factors that have importance for cancer patients. The study objective was to determine whether hypoxia-inducible factor-1α (HIF-1α) and prominin-1 (CD133) in pleural fluid (P) and serum (S) could be used as biomarkers for diagnosis of lymph node involvement in patients with MPE. Materials and methods Fifty-six patients with MPE and 30 healthy control subjects were included. Computerized tomography (CT) and positron emission tomography (PET) were used to diagnose pleural effusion. Patients with malignant cells in pleural fluid cytological examination were included in the MPE group. Thirty-five patients with lymph node metastases on CT were included in the LNM-positive MPE group. Serum and pleural fluid HIF-1α and CD-133 concentrations were measured manually via enzyme-linked immunosorbent assay (ELISA). Results Serum concentrations of HIF-1α and CD133 were higher in MPE patients. It was found that CD133/HIF-1α (S) ratio was higher in the malignant patient group with positive lymph node involvement than in the negative group, while concentrations of HIF-1α (P) were lower. Pleural fluid HIF-1α and CD133/HIF-1α (S) ratio had sufficient performance in diagnosing lymphatic metastases in patients with MPE (AUC = 0.90 and 0.83, respectively). Conclusions In conclusion, serum HIF-1α and CD133 concentrations were higher in patients with MPE, consistent with our hypothesis. Concentrations of HIF-1α (P) and CD133/HIF-1α (S) ratio can be used as biomarkers in diagnosing lymph node involvement in MPE patients, according to this experiment.

Immunohistochemistry and oxygen saturation endoscopic imaging reveal hypoxia in submucosal invasive esophageal squamous cell carcinoma. Cancer Med 2023; 12:15809-15819. [PMID: 37329213 PMCID: PMC10469640 DOI: 10.1002/cam4.6217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 05/24/2023] [Accepted: 05/29/2023] [Indexed: 06/18/2023] Open
Abstract
BACKGROUND Hypoxic microenvironment is prominent in advanced esophageal squamous cell carcinoma (ESCC). However, it is unclear whether ESCC becomes hypoxic when it remains in the mucosal layer or as it invades the submucosal layer. We aimed to investigate whether intramucosal (Tis-T1a) or submucosal invasive (T1b) ESCC becomes hypoxic using endoscopic submucosal dissection samples. METHODS We evaluated the expression of hypoxia markers including hypoxia inducible factor 1α (HIF-1α), carbonic anhydrase IX (CAIX), and glucose transporter 1 (GLUT1) by H-score and vessel density by microvessel count (MVC) and microvessel density (MVD) for CD31 and α-smooth muscle actin (α-SMA) with immunohistochemical staining (n = 109). Further, we quantified oxygen saturation (StO2 ) with oxygen saturation endoscopic imaging (OXEI) (n = 16) and compared them to non-neoplasia controls, Tis-T1a, and T1b. RESULTS In Tis-T1a, cccIX (13.0 vs. 0.290, p < 0.001) and GLUT1 (199 vs. 37.6, p < 0.001) were significantly increased. Similarly, median MVC (22.7/mm2 vs. 14.2/mm2 , p < 0.001) and MVD (0.991% vs. 0.478%, p < 0.001) were markedly augmented. Additionally, in T1b, the mean expression of HIF-1α (16.0 vs. 4.95, p < 0.001), CAIX (15.7 vs. 0.290, p < 0.001), and GLUT1 (177 vs. 37.6, p < 0.001) were significantly heightened, and median MVC (24.8/mm2 vs. 14.2/mm2 , p < 0.001) and MVD (1.51% vs. 0.478%, p < 0.001) were markedly higher. Furthermore, OXEI revealed that median StO2 was significantly lower in T1b than in non-neoplasia (54% vs. 61.5%, p = 0.00131) and tended to be lower in T1b than in Tis-T1a (54% vs. 62%, p = 0.0606). CONCLUSION These results suggest that ESCC becomes hypoxic even at an early stage, and is especially prominent in T1b.

Abstract
Cancer is characterized by disrupted molecular variables caused by cells that deviate from regular signal transduction. The uncontrolled segment of such cancerous cells annihilates most of the tissues that contact them. Gene therapy, immunotherapy, and nanotechnology advancements have resulted in novel strategies for anticancer drug delivery. Furthermore, diverse dispersion of nanoparticles in normal stroma cells adversely affects the healthy cells and disrupts the crosstalk of tumour stroma. It can contribute to cancer cell progression inhibition and, conversely, to acquired resistance, enabling cancer cell metastasis and proliferation. The tumour's microenvironment is critical in controlling the dispersion and physiological activities of nano-chemotherapeutics which is one of the targeted drug therapy. As it is one of the methods of treating cancer that involves the use of medications or other substances to specifically target and kill off certain subsets of malignant cells. A targeted therapy may be administered alone or in addition to more conventional methods of care like surgery, chemotherapy, or radiation treatment. The tumour microenvironment, stromatogenesis, barriers and advancement in the drug delivery system across tumour tissue are summarised in this review.

Abstract
INTRODUCTION Esophageal cancer is an aggressive malignancy with high mortality. Optimal treatment of esophageal cancer remains an elusive goal. Ribonucleic acid (RNA) interference is a novel potential targeted approach to treat esophageal cancer. Targeting oncogenes that can alter critical cellular functions with silencing RNA molecules is a promising approach. The silencing of specific oncogenes in esophageal cancer cells in the experimental setting has been shown to decrease the expression of oncogenic proteins. This has resulted in cell apoptosis, reduction in cell proliferation, reduced invasion, migration, epithelial-mesenchymal transition, decrease in tumor angiogenesis and metastasis, and overcoming drug resistance. The Hedgehog (Hh) signaling pathway has been shown to be involved in esophageal adenocarcinoma formation in a reflux animal model. In addition to Hh, we will focus on other targets with clinical potential in the treatment of esophageal cancer. MATERIALS AND METHODS We searched for articles published from 2005 to August 2020 that studied the siRNA effects on inhibiting esophageal cancer formation in experimental settings. We used combinations of the following terms for searching: "esophageal cancer," "RNA interference," "small interfering RNA," "siRNA," "silencing RNA," "Smoothened (Smo)," "Gli," "Bcl-2," "Bcl-XL," "Bcl-W,″ "Mcl-1," "Bfl-1," "STAT3,"and "Hypoxia inducible factor (HIF)". A total of 21 relevant articles were found. RESULTS AND CONCLUSIONS Several proto-oncogenes/oncogenes including Hh pathway mediators, glioma-associated oncogene homolog 1 (Gli-1), Smoothened (Smo), and antiapoptotic Bcl-2 have potential as targets for silencing RNA in the treatment of esophageal cancer.

Abstract
Ovarian cancer is the eighth most commonly diagnosed cancer among women worldwide. Even with the development of novel drugs, nearly one-half of the patients with ovarian cancer die within five years of diagnosis. These situations indicate the need for novel therapeutic agents for ovarian cancer. Increasing evidence has shown that hypoxia-inducible factor-1α(HIF-1α) plays an important role in promoting malignant cell chemoresistance, tumour metastasis, angiogenesis, immunosuppression and intercellular interactions. The unique microenvironment, crosstalk and/or interaction between cells and other characteristics of ovarian cancer can influence therapeutic efficiency or promote the disease progression. Inhibition of the expression or activity of HIF-1α can directly or indirectly enhance the therapeutic responsiveness of tumour cells. Therefore, it is reasonable to consider HIF-1α as a potential therapeutic target for ovarian cancer. In this paper, we summarize the latest research on the role of HIF-1α and molecules which can inhibit HIF-1α expression directly or indirectly in ovarian cancer, and drug clinical trials about the HIF-1α inhibitors in ovarian cancer or other solid malignant tumours.

Abstract
Aim This meta-analysis aimed to evaluate the association of HIF-1α expression with clinicopathological features and overall survival (OS) of patients with digestive system malignancies. Background Numerous studies have demonstrated that hypoxia-inducible factor-1α (HIF-1α) is abnormally expressed in various solid tumors. However, the clinicopathological features and prognostic value of HIF-1α expression in patients with digestive system malignancies remain controversial. Methods A literature search in PubMed, Web of Science, and Scopus databases was performed to identify all relevant studies published in English until 15 October 2020. The pooled effect was calculated to evaluate the association between HIF-1α expression and clinicopathological features and overall survival in cancer patients. Pooled odds ratios (ORs) or hazard ratios (HRs) with a 95% confidence interval (CI) were calculated using fixed- or random-effects model based on between-study heterogeneity. Results A total of 44 eligible studies with 5,964 patients were included. The pooled results indicated a positive association of HIF-1α overexpression with poor overall survival (OS) (HR=1.990, 95% CI: 1.615-2.453, p<0.001) and disease-free survival (DFS) (HR=1.90, 95% CI: 1.084-3.329, p=0.043). Meta-analysis results showed that HIF-1α level expression was significantly associated with positive lymph node metastasis (OR=1.869, 95% CI: 1.488-2.248, p<0.001), distance metastasis (OR=2.604, 95% CI: 1.500-4.519, p<0.001), tumor stage (OR=1.801, 95% CI: 1.437-2.257, p<0.001) and tumor size (OR=1.392. 95% CI: 1.068-1.815, p=0.014). Conclusion This meta-data suggest that HIF-1α expression might serve as an independent prognostic marker and a promising therapeutic target in patients with digestive system malignancies.

Biochimie 2021; 190:124-131. [PMID: 34329720 DOI: 10.1016/j.biochi.2021.07.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 07/16/2021] [Accepted: 07/21/2021] [Indexed: 12/11/2022]
Abstract
Paraspeckles are RNA-protein structures within the nucleus of mammalian cells, capable of orchestrating various biochemical processes. An overexpression of the architectural component of paraspeckles, a long non-coding RNA called NEAT1 (Nuclear Enriched Abundant Transcript 1), has been linked to a variety of cancers and is often associated with poor patient prognosis. Thus, there is an accumulating interest in the role of paraspeckles in carcinogenesis, however there is a limited understanding of how NEAT1 expression is regulated. Here, we demonstrate that both nuclear G-quadruplex (G4) and paraspeckle formation are significantly increased in a human breast cancer cell line compared to non-tumorigenic breast cells. Moreover, we identified and characterized G4-forming sequences within the NEAT1 promoter and demonstrate stabilization of G4 DNA with a G4-stabilizing small molecule results in a significant alteration in both paraspeckle formation and NEAT1 expression. This G4-mediated alteration of NEAT1 at both the transcriptional and post-transcriptional levels was evident in U2OS osteosarcoma cells, MCF-7 breast adenocarcinoma and MDA-MB-231 triple negative breast cancer cells.

Abstract
Hypoxia in solid tumors is an important predictor of treatment resistance and poor clinical outcome. The significance of hypoxia in the development of resistance to radiotherapy has been recognized for decades and the search for hypoxia-targeting, radiosensitizing agents continues. This review summarizes the main hypoxia-related processes relevant for radiotherapy on the subcellular, cellular and tissue level and discusses the significance of hypoxia in radiation oncology, especially with regard to the current shift towards hypofractionated treatment regimens. Furthermore, we discuss the strategies to interfere with hypoxia for radiotherapy optimization, and we highlight novel insights into the molecular pathways involved in hypoxia that might be utilized to increase the efficacy of radiotherapy.

Hypoxia induces chemoresistance of esophageal cancer cells to cisplatin through regulating the lncRNA-EMS/miR-758-3p/WTAP axis. Aging (Albany NY) 2021; 13:17155-17176.

Abstract
Hypoxia contributes significantly to the development of chemoresistance of many malignancies including esophageal cancer (EC). Accumulating studies have indicated that long non-coding RNAs play important roles in chemotherapy resistance. Here, we identified a novel lncRNA-EMS/miR-758-3p/WTAP axis that was involved in hypoxia-mediated chemoresistance to cisplatin in human EC. Hypoxia induced the expressions of lncRNA EMS and WTAP, and reduced the expression of miR-758-3p in EC cell line ECA-109. In addition, the expressions of EMS and WTAP were required for the hypoxia-induced drug resistance to cisplatin in EC cells, while overexpression of miR-758-3p reversed such chemoresistance. The targeting relationships between EMS and miR-758-3p, as well as miR-758-3p and WTAP, were verified by luciferase-based reporter assays and multiple quantitative assays after gene overexpression/knockdown. Moreover, we found significant correlations between tumor expressions of these molecules. Notably, higher levels of EMS/WTAP, or lower levels of miR-758-3p in tumors predicted worse survivals of EC patients. Furthermore, in a xenograft mouse model, targeted knockdown of EMS and WTAP in ECA-109 cells markedly attenuated the resistance of tumors to cisplatin treatments. Our study uncovers a critical lncRNA-EMS/miR-758-3p/WTAP axis in regulating hypoxia-mediated drug resistance to cisplatin in EC.

Abstract
Aim: To investigate hypoxia-inducible factor-1α (HIF-1α) and histone methylation markers as potential indicators of prognosis in esophageal squamous cell carcinoma (ESCC). Patients & methods: The prognostic value of HIF-1α and histone methylation markers levels was analyzed using Kaplan-Meier survival analysis. Results: HIF-1α protein expression was higher in ESCC tumors than in paracancerous tissues. Histone H3 Lys9 trimethylation (H3K9me3), histone H3 Lys27 trimethylation (H3K27me3), histone H3 Lys4 trimethylation (H3K4me3) and histone H4 Lys20 trimethylation (H4K20me3) were significantly upregulated in ESCC tissues. HIF-1α was only positively correlated with H3K9me3 and H3K4me3 expression. Kaplan-Meier analysis indicated that H3K9me3, H3K27me3, H4K20me3 and histone H3 Lys36 trimethylation (H3K36me3) were independent indicators of prognosis for ESCC. Conclusion: This study identified a pattern of epigenetic methylation markers and HIF-1α expression in ESCC, and their combined evaluation might improve survival prediction for ESCC patients.

Abstract
Objective Hypoxia is prevalent in tumors and plays a pivotal role in resistance to chemoradiotherapy. 18F-MISO (18F-labeled fluoromisonidazole) is currently the preferred choice of PET hypoxia tracers in clinical practice, but has severe disadvantages involving complex labeling methods and low efficient imaging due to lipophilicity. We aimed to design a novel nitroimidazole derivative labeled by 18F via a chelation technique to detect hypoxic regions and provide a basis for planning radiotherapy. Materials and Methods First, we synthesized a 2-nitroimidazole precursor, 2-[4-(carboxymethyl)-7-[2-(2-(2-nitro-1H-imidazol-1-yl)acetamido)ethyl]-1,4,7-triazanonan-1-yl]acetic acid (NOTA-NI). For 18F-labeling, a 18F solution was reacted with a mixture of AlCl3 and NOTA-NI at pH 3.5 and 100°C for 20 min, and the radiochemical purity and stability were evaluated. Biological behaviors of Al18F-NOTA-NI were analyzed by an uptake study in ECA109 normoxic and hypoxic cells, and a biodistribution study and microPET imaging in ECA109 xenografted mice. Results Al18F-NOTA-NI required a straightforward and efficient labeling procedure compared with 18F-MISO. The uptake values were distinctly higher in hypoxic tumor cells. Animal studies revealed that the imaging agent was principally excreted via the kidneys. Due to hydrophilicity, the radioactivities in blood and muscle were decreased, and we could clearly distinguish xenografted tumors from para-carcinoma tissue by PET imaging. Conclusions The nitroimidazole tracer Al18F-NOTA-NI steadily accumulated in hypoxic areas in tumors and was rapidly eliminated from normal tissue. It appears to be a promising candidate for hypoxia imaging with high sensitivity and resolution.

Abstract
Photodynamic therapy (PDT) shows great promise for the treatment of colon cancer. However, practically, it is a great challenge to use a nanocarrier for the codelivery of both the photosensitizer and oxygen to improve PDT against PDT-induced hypoxia, which is closely related to tumor metastasis. Hence, an effective strategy was proposed to develop an oxygen self-supplemented PDT nanocarrier based on the ultrasonic dispersion of perfluorooctyl bromide (PFOB) liquid into the preformed porphyrin grafted lipid (PGL) nanoparticles (NPs) with high porphyrin loading content of 38.5%, followed by entrapping oxygen. Interestingly, the orderly arranging mode of porphyrins and alkyl chains in PGL NPs not only guarantees a high efficacy of singlet oxygen generation but also reduces fluorescence loss of porphyrins to enable PGL NPs to be highly fluorescent. More importantly, PFOB liquid was stabilized inside PGL NPs with an ultrahigh loading content of 98.15% due to the strong hydrophobic interaction between PGL and PFOB molecules, facilitating efficient oxygen delivery. Both in vitro and in vivo results demonstrated that the obtained O2@PFOB@PGL NPs could act as a prominent oxygen reservoir and effectively replenish oxygen into the hypoxic tumors with no need for external stimulation, conducive to augmented singlet oxygen generation, hypoxia relief, and subsequent downregulation of COX-2 expression. As a result, the use of O2@PFOB@PGL NPs for hypoxia relief dramatically inhibits tumor growth and liver metastasis in an HT-29 colon cancer mouse model. In addition, the O2@PFOB@PGL NPs could serve as a bimodal contrast agent to enhance fluorescence and CT imaging, visualizing nanoparticle accumulation to guide the subsequent laser irradiation for precise PDT.

Abstract
Background Nodal metastasis is a critical factor in predicting the prognosis of oral squamous cell carcinoma (OSCC). When patients present with a clinically positive neck, the treatment of choice is radical neck dissection. However, management of a clinically negative neck is still a subject of significant controversy. Aim This study was carried out in order to propose a model to predict regional lymph node metastasis of OSCC using histological parameters such as tumour stage, tumour size, pattern of invasion (POI), differentiation of tumour, and host immune response, together with the expression levels of six biomarkers (periostin, HIF-1α, MMP-9, β-catenin, VEGF-C, and EGFR), and, furthermore, to compare the impact of all these parameters on recurrence and 3 yr and 5 yr survival rates. Materials and Method. Histological materials collected from the archives were used to evaluate histological parameters and immunohistochemical profiles. Standard methods were used for immunohistochemistry and for evaluation of results. Data related to recurrence and survival (3 and 5 years) was also recorded. Clinical data was collected from patients' records. Results Male to female ratio was 3 : 1. The commonest site of OSCC was the buccal mucosa, and majority of them were T3 or T4 tumours presented at stage 4. 62.5% of the tumours were well differentiated. Three-year and 5-year survival rates were significantly associated with lymph node metastasis and recurrence. POI was significantly correlated with tumour size, stage, 3-year survival, EGFR, HIF-1α, periostin, and MMP-9 (p < 0.05). Expression of EGFR showed a direct association with metastasis (p < 0.05). Conclusion POI, level of differentiation, and expression of EGFR are independent prognostic markers for lymph node metastasis. Therefore, these parameters may help in treatment planning of a clinically negative neck.

Abstract
Metastasis remains a notable issue in patients with newly diagnosed colorectal carcinomas (CRC). Although anti-angiogenic therapies target metastatic diseases, hypoxia-inducible factor-1 α (HIF-1α) and vascular endothelial growth factor (VEGF) status are routinely evaluated in primary tumors as metastatic sites are infrequently biopsied. The present study aimed to investigate the expression and significance of HIF-1α, VEGF and microvascular density (MVD) in primary tumors and corresponding metastatic CRC tissues. HIF-1α, VEGF and CD34 status were analyzed via immunohistochemistry analysis in 46 patients who underwent surgical resection of primary CRC (35 colon and 11 rectum) and matched metastases (lymph node and liver metastases) in Shandong Cancer Hospital. The association between selected biomarker status and clinicopathological characteristics was analyzed, and expression levels in primary tumors and corresponding metastases were compared. A total of 46 paired colorectal primary tumor and synchronous metastases samples were acquired for analysis using a standardized HIF-1α, VEGF and CD34 immunohistochemical procedure. The results demonstrated that the positive rates of HIF-1α and VEGF in primary CRC were 70 and 73.9%, respectively. HIF-1α (60.9%) and VEGF (58.7%) expression decreased in the lymph metastatic samples compared with primary CRC. Conversely, the level of MVD in primary tumors was significantly higher compared with metastatic tumors. No significant differences were demonstrated between HIF-1α and VEGF expression and the different clinicopathological features in primary CRC and corresponding metastases. Primary carcinomas and matched metastatic tissues demonstrated a moderate level of consistent immunoreactivity for HIF-1α and VEGF. HIF-1α, VEGF and CD34 were expressed in both primary tumors and corresponding metastases of CRC, suggesting that they may be involved in the development of metastasis. HIF-1α and VEGF expression in primary sites was consistent with that observed in metastases; however, it varied from that exhibited in MVD. The current analysis will improve the current understanding of the metastasis models and provide further evidence for evaluating the response to HIF-1α and VEGF inhibitors.

Abstract
Background: In microenvironment of malignant tumors, Hypoxia-Inducible Factors (HIF), most importantly HIF-1α, play an important role in regulation of adaptive biological response to hypoxia, promoting angiogenesis and metastasis. However, the underlying mechanism that HIF-1α regulates metastasis needs to be further clarified. Methods: The expressions of HIF-1α and SP1 were detected in 182 samples of esophageal squamous cell carcinoma (ESCC) and adjacent normal tissues by immunohistochemistry (IHC), and the correlation between the expression levels of HIF-1α and SP1 was analyzed. The expression of HIF-1α in ESCC cell lines TE1 and KYSE30 was then detected using qRT-PCR and western blot. The potential binding sites of HIF-1α on the SP1 promoter were analyzed using UCSC and JASPAR databases, verified by chromosomal immunoprecipitation (ChIP) assay and qRT-PCR. The effects of HIF-1α and SP1 on ESCC cell migration and invasion were then tested with Transwell and Matrigel experiments. Results: The expression of HIF-1α in cancer tissues is higher than adjacent normal tissues, and is correlated with metastasis, recurrence and poor prognosis. Upon silencing HIF-1α by siRNA, the invasion and migration ability of ESCC cells were significantly inhibited, which could be restored by the overexpression of SP1. Hypoxic conditions significantly increased the expression of HIF-1α and SP1 at both protein and mRNA levels in ESCC cells. HIF-1α enhanced SP1 transcription through binding to the promoter region. The expression of protein and mRNA levels of SP1 was decreased by silencing HIF-1α in cells. In contrast, overexpression of HIF-1α significantly increased the mRNA and protein levels of SP1. The expression of SP1 in ESCC was positively correlated with the protein expression of HIF-1α and poor prognosis. Conclusion: The results of our study indicate that HIF-1α promotes metastasis of ESCC by targeting SP1 in a hypoxic microenvironment. Further study on this mechanism may elucidate the possibility of HIF-1α and SP1 as new targets for the treatment of ESCC.

Abstract
Background Despite modern imaging modalities, staging of clinically staged T2N0M0 (cT2N0M0) oesophageal cancer is suboptimal, often leading to overtreatment. Endoscopic resection – the first-line therapy for early localised tumours – could be used to improve staging and to attain predictors of nodal upstaging enabling more stage-guided treatment decisions. Objective A systematic literature review and a meta-analysis were conducted to assess the prevalence and the pathological risk factors of lymph node metastases in cT2N0M0 oesophageal cancer. Methods Databases of PUBMED, EMBASE and Cochrane were searched for literature. The primary outcome was lymph node metastases determined after primary surgical resection. Results Nine studies with a total of 1650 cT2N0M0 patients were included. The prevalence of lymph node metastases was 43% (95% confidence interval: 35–50%) with heterogeneity being high across studies (I2 = 0.86, p < 0.001). Factors potentially attainable by endoscopic resection and having a significant association with lymph node metastases were invasion depth, differentiation grade, tumour size, depth of invasion in the muscularis propria and lymphovascular invasion. Conclusions Clinical lymph node staging is inaccurate in almost half of cT2N0M0 oesophageal cancer. Endoscopic resection is a promising diagnostic modality that might even be a valid alternative to surgery in selected patients without high-risk features, but further evidence is warranted.

Abstract
Hypoxia as well as metabolism are central hallmarks of cancer, and hypoxia-inducible factors (HIFs) and metabolic effectors are crucial elements in oxygen-compromised tumor environments. Knowledge of changes in the expression of metabolic proteins in response to HIF function could provide mechanistic insights into adaptation to hypoxic stress, tumorigenesis, and disease progression. We analyzed time-resolved alterations in metabolism-associated protein levels in response to different oxygen potentials across breast cancer cell lines. Effects on the cellular metabolism of both HIF-dependent and -independent processes were analyzed by reverse-phase protein array profiling and a custom statistical model. We revealed a strong induction of glucose transporter 1 (GLUT1) and lactate dehydrogenase A (LDHA) as well as reduced glutamate-ammonia ligase (GLUL) protein levels across all cell lines tested as consistent changes upon hypoxia induction. Low GLUL protein levels were correlated with aggressive molecular subtypes in breast cancer patient data sets and also with hypoxic tumor regions in a xenograft mouse tumor model. Moreover, low GLUL expression was associated with poor survival in breast cancer patients and with high HIF-1α-expressing patient subgroups. Our data reveal time-resolved changes in the regulation of metabolic proteins under oxygen-deprived conditions and elucidate GLUL as a strong responder to HIFs and the hypoxic environment.

Abstract
Background Marjolin ulcer (MU) is an aggressive cutaneous malignancy. Typically, MU occurs over a period of time in post-burn and/or post-traumatic lesions and scars. However, the pathogenesis of scar carcinogenesis and MU development remains to be elucidated. The present study aimed to investigate the long noncoding RNA (lncRNA) and messenger RNA (mRNA) expression profiling in MU, which could provide new information on the potential molecular mechanisms of MU development. Material/Methods The lncRNA microarray analysis was conducted in normal skin, scar, and MU tissue, and quantitative real-time PCR experiment was carried out to validate the reliability of the microarray data. Furthermore, a series of integrative bioinformatic approaches were applied to decipher the function of differentially expressed lncRNAs. Results A total of 7130 lncRNAs and 9867 mRNAs were differentially expressed among normal skin, scar, and MU tissues. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis demonstrated that these aberrantly expressed transcripts were mainly involved in cell cycle, immune response, and the p53 signaling pathway. Series Test of Cluster analysis indicated certain dysregulated lncRNAs were expressed with a gradually increasing or decreasing trend and might participated in malignant transformation of scar tissue postburn. Co-expression analysis showed 5 selected lncRNAs might regulate cell proliferation through the p53 signaling pathway. Finally, the competing endogenous RNA (ceRNA) network indicated that lncRNA uc001oou.3 might be implicated in ceRNA mechanism during MU development. Conclusions Taken together, our study implied the aberrant expression of lncRNAs may play an important role in the pathogenesis and development of MU, and the exact mechanism warrants further investigation.

Abstract
Cancer progression often benefits from the selective conditions present in the tumour microenvironment, such as the presence of cancer-associated fibroblasts (CAFs), deregulated ECM deposition, expanded vascularisation and repression of the immune response. Generation of a hypoxic environment and activation of its main effector, hypoxia-inducible factor-1 (HIF-1), are common features of advanced cancers. In addition to the impact on tumour cell biology, the influence that hypoxia exerts on the surrounding cells represents a critical step in the tumorigenic process. Hypoxia indeed enables a number of events in the tumour microenvironment that lead to the expansion of aggressive clones from heterogeneous tumour cells and promote a lethal phenotype. In this article, we review the most relevant findings describing the influence of hypoxia and the contribution of HIF activation on the major components of the tumour microenvironment, and we summarise their role in cancer development and progression.

Abstract
Background Benign prostatic hyperplasia (BPH) is one of the most common diseases in middle-age or older men. Increasing evidence has shown that BPH is associated with hypoxia microenvironment. Methods We retrospectively collected patient data and tissue samples from fetal prostates(FP), normal prostates(NP), intra-acinar of BPH, peri-acinar of BPH, prostate cancers and sarcomas of prostate. The expression of HIF-1α, as well as VEGF was visualized by immunohistochemistry and statistically analyzed with clinical parameters. Results Expression of HIF-lα was observed in intra-acinar of BPH (69.5%), prostate cancer (85.7%) and all FPs, while NP and peri-acinar of BPH tissues were all stained negative. HIF-lα levels in FPs and the malignant tumors were higher than BPH tissues(p < 0.05), and the expression of HIF-lα in intra-acinar of BPH was higher than NP and peri-acinar of BPH (p < 0.05). The expression of HIF-lα was correlated with the weight of intra-acinar of prostate (p < 0.05). And patients with prostate weight larger that 72.45g were prone to have HIF-lα moderate-positive expression, according to the ROC curve (AUC = 0.734, 95%CI = 0.630-0.838). Moreover, the risk of acute urine retention (AUR) for HIF-lα moderate-positive patients increased significantly (OR=5.517, 95%CI = 2.434-12.504). Conclusions HIF-lα expression is increased in highly proliferative prostate tissues and correlated with the weight of intra-acinar prostate. Moreover, HIF-lα is also an independent risk factor for AUR occurrence in BPH patients.

Abstract
Cancer, the main cause of human deaths in the modern world is a group of diseases. Anticancer drug discovery is a challenge for scientists because of involvement of multiple survival pathways of cancer cells. An extensive study on the regulation of each step of these pathways may help find a potential cancer target. Up-regulated HIF-1 expression and altered metabolic pathways are two classical characteristics of cancer. Oxygen-dependent (through pVHL, PHDs, calcium-mediated) and independent (through growth factor signaling pathway, mdm2 pathway, HSP90) regulation of HIF-1α leads to angiogenesis, metastasis, and cell survival. The two subunits of HIF-1 regulates in the same fashion through different mechanisms. HIF-1α translation upregulates via mammalian target of rapamycin and mitogen-activated protein kinase signaling pathways, whereas HIF-1β through calmodulin kinase. Further, the stabilized interactions of these two subunits are important for proper functioning. Also, metabolic pathways crucial for the formation of building blocks (pentose phosphate pathway) and energy generation (glycolysis, TCA cycle and catabolism of glutamine) are altered in cancer cells to protect them from oxidative stress and to meet the reduced oxygen and nutrient supply. Up-regulated anaerobic metabolism occurs through enhanced expression of hexokinase, phosphofructokinase, triosephosphate isomerase, glucose 6-phosphate dehydrogenase and down-regulation of aerobic metabolism via pyruvate dehydrogenase kinase and lactate dehydrogenase which compensate energy requirements along with high glucose intake. Controlled expression of these two pathways through their common intermediate may serve as potent cancer target in future.

Abstract
Many studies have analyzed the relationship between hypoxia inducible factor 1 alpha expression and its relation to differentiation, lymph node metastasis, and other clinicopathological variables of esophageal carcinoma, but the results are still inconsistent. This meta-analysis was carried out to explore hypoxia inducible factor 1 alpha in esophageal carcinoma and its correlation with clinicopathological features and prognosis, in order to provide comprehensive reference for clinic. A total of 18 studies including 1566 patients with esophageal squamous cell carcinoma were enrolled. The results showed that compared with para-carcinoma tissue, the expression of hypoxia inducible factor 1 alpha was significantly enhanced (odds ratio = 0.122, 95% confidence interval = 0.074-0.201, p = 0.000); hypoxia inducible factor 1 alpha was associated with differentiation (odds ratio = 1.458, 95% confidence interval = 1.108-1.920, p = 0.007), T classification (odds ratio = 0.457, 95% confidence interval = 0.265-0.786, p = 0.005), lymph node metastasis (odds ratio = 0.337, 95% confidence interval = 0.185-0.614, p = 0.000), and pathological tumor-node-metastasis stage (odds ratio = 0.362, 95% confidence interval = 0.177-0.740, p = 0.005), whereas there was no relation to histological grade, lymphatic vessel invasion, blood vessel invasion, 3- to 5-year overall survival and disease-free survival. Patients with hypoxia inducible factor 1 alpha overexpression had poor differentiation, increased depth of tumor invasion, more lymph node metastasis, and late pathological tumor-node-metastasis stage. Hypoxia inducible factor 1 alpha could be an indicator for differentiation, T classification, lymph node metastasis, and pathological tumor-node-metastasis stage, and it is worth further study.

Abstract
PURPOSE In this systematic review, the existing evidence of available hypoxia-associated molecular response biomarkers in esophageal cancer (EC) patients is summarized and set into the context of the role of hypoxia in the prediction of esophageal cancer, treatment response and treatment outcome. METHODS A systematic literature search was performed in Web of Science, MEDLINE, and PubMed databases using the keywords: hypoxia, esophagus, cancer, treatment outcome and treatment response. Eligible publications were independently evaluated by two reviewers. In total, 22 out of 419 records were included for systematic review. The described search strategy was applied weekly, with the last update being performed on April 3rd, 2017. RESULTS In esophageal cancer, several (non-)invasive biomarkers for hypoxia could be identified. Independent prognostic factors for treatment response include HIF-1α, CA IX, GLUT-1 overexpression and elevated uptake of the PET-tracer 18F-fluoroerythronitroimidazole (18F-FETNIM). Hypoxia-associated molecular responses represents a clinically relevant phenomenon in esophageal cancer and detection of elevated levels of hypoxia-associated biomarkers and tends to be associated with poor treatment outcome (i.e., overall survival, disease-free survival, complete response and local control). CONCLUSION Evaluation of tumor micro-environmental conditions, such as intratumoral hypoxia, is important to predict treatment outcome and efficacy. Promising non-invasive imaging-techniques have been suggested to assess tumor hypoxia and hypoxia-associated molecular responses. However, extensive validation in EC is lacking. Hypoxia-associated markers that are independent prognostic factors could potentially provide targets for novel treatment strategies to improve treatment outcome. For personalized hypoxia-guided treatment, safe and reliable makers for tumor hypoxia are needed to select suitable patients.

Abstract
INTRODUCTION Hypoxia Inducible Factor-1 (HIF-1) is a mediator enabling cell adaptation to hypoxia. It plays its role mainly through transcription of many target genes including Glucose Transporter-1 (GLUT-1) gene. AIM The present work aimed at evaluating the pattern and distribution of HIF-1α and GLUT-1 in each case and control. MATERIALS AND METHODS A case-control and retrospective study was conducted on archival blocks diagnosed from pathology department as, Basal Cell Carcinoma (BCC, 20 cases), cutaneous Squamous Cell Carcinoma (SCC, 20 cases) and 20 normal site-matched skin biopsies from age and gender-matched healthy subjects as a control. Evaluation of both HIF-1α and GLUT1 expression using standard immunohistochemical techniques was performed on cut sections from selected paraffin embedded blocks. RESULTS HIF-1α was expressed in 90%, 35% and 100% of normal skin, BCC and SCC tumour islands respectively. It was up regulated in both BCC and SCC compared with normal skin (p= 0.001, p<0.001 respectively). GLUT-1 was expressed in 100%, 70% and 100% of normal skin, BCC and SCC tumour islands respectively. It was down regulated in Non Melanoma Skin Cancer (NMSC) cases compared with normal skin (p=0.004). HIF-1α and GLUT-1 localization in tumour nests was central, peripheral or central and peripheral. Both HIF-1α and GLUT-1 showed variable expression in stroma, adnexa and inflammatory cells. No significant correlation was found between Histo (H) score or expression percentage values of HIF-1α and those of GLUT-1 in tumour islands or in overlying epidermis either in BCC or SCC. CONCLUSION HIF-1α may have a role in NMSC pathogenesis through adaptation to hypoxia which results from excessive proliferation. GLUT-1 down regulation in NMSC may be explained by its consumption by proliferating tumour cells. The expression of HIF-1α and GLUT-1 in normal epidermis, stromal and adnexal structures needs further research.

Abstract
Objective Bone morphogenetic protein receptor 2 (BMPR2) and hypoxia-inducible factor 1-α (HIF1-α) existed abnormal expression in several types of cancer. However, their expressions and related roles in osteosarcoma are largely unknown. Methods To investigate the clinical significance of BMPR2 and HIF1-α in osteosarcoma, we analyzed their expression levels in 103 osteosarcoma specimens by immunochemistry. Meanwhile, we conducted a follow-up to examine the metastatic behavior and overall survival (OS) of osteosarcoma patients. Results Among 103 tissues, 61 cases had BMPR2-positive expression and 57 cases had HIF1-α positive expression. A significant correlation was noticed between BMPR2 and HIF1-α expression in osteosarcoma specimens (P=0.035). Receiver-operating characteristic (ROC) curves were calculated to investigate the predictive value of the two markers in tumor metastasis. By means of univariate and multivariate analysis, BMPR2 and HIF1-α expression, as well as higher tumor grade, were identified as significant risk factors for OS in patients with osteosarcoma. Kaplan-Meier survival analysis revealed that the patients with BMPR2 and HIF1-α positive expression had worse OS compared with patients with BMPR2-negative or HIF1-α-negative staining. Conclusions It can be concluded that BMPR2 and HIF1-α expression is highly correlated with metastatic behavior in patients with osteosarcoma and can serve as predictive markers for metastasis and OS of these patients.

Siah-1 is associated with expression of hypoxia-inducible factor-1α in oral squamous cell carcinoma. Auris Nasus Larynx 2016; 44:213-219. [PMID: 27616748 DOI: 10.1016/j.anl.2016.06.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2015] [Revised: 05/12/2016] [Accepted: 06/10/2016] [Indexed: 12/23/2022]
Abstract
OBJECTIVE Hypoxia-inducible factor-1 (HIF-1) is a heterodimeric basic helix-loop-helix transcription factor composed of the HIF-1α and HIF-1β subunits. HIF-1 is a central regulator of responses to hypoxia; it enhances metastasis-related factors such as matrix metalloproteinases and vascular endothelial growth factor (VEGF). We have reported critical roles for HIF-1α in tumor microenvironments, and oncogenic properties of HIF-1α have been suggested in malignancies. Seven in absentia homologue (Siah) appeared to upregulate HIF-1 production, which prompted us to investigate the Siah association with HIF-1α expression in oral squamous cell carcinoma (OSCC). METHODS Samples from fifty-five patients with OSCC were evaluated by immunohistochemistry for the protein expressions of Siah-1 and -2, HIF-1α, and VEGF. The expression levels of each protein and clinicopathological data were statistically analyzed. RESULTS Siah-1 and, Siah-2, HIF-1α, and VEGF were immunolocalized on the cell membranes and cytoplasm of the tumor cells. The expression of Siah-1 showed a linear dependence on the expression of HIF-1α (r=0.627, p<0.001). In 17 cases of the large tumor size category (T3 and 4), the mean Siah-1 expression score was significantly higher than in 41 cases of the small tumor size category (T1 and 2; p=0.001). In addition, in 16 cases of the lymph node metastasis-positive category (N1-3), the mean Siah-1 expression score was significantly higher than that in 42 cases of the lymph node metastasis-negative category (N0, p=0.001). CONCLUSION These results suggested that the expressions of Siah-1 and HIF-1α were clearly correlated in OSCC. Moreover, Siah-1 appears to be correlated with clinicopathological data, particularly tumor size.

Abstract
Sorafenib, a multi-kinase inhibitor, has shown its promising antitumor effect in a series of clinical trials, and has been approved as the current standard treatment for advanced hepatocellular carcinoma (HCC). 8-Bromo‑7-methoxychrysin (BrMC) is a novel chrysin synthetic analogue that has been reported to inhibit the growth of various tumor cells and possess properties for targeting liver cancer stem cells (LCSCs) . The present study investigated the synergistic targeting effects on the properties of liver cancer stem-like cells (LCSLCs) by a combination of sorafenib and BrMC in SMMC-7721 cell line. We also investigated whether this effect involves regulation of HIF-1α, Twist and NF-κB protein. We found that the sphere-forming cells (SFCs) from the SMMC‑7721 cells possessed the properties of LCSLCs. Sorafenib diminished the self-renewal capacity and downregulated the expression of stem cell biomarkers (CD133, CD44 and ALDH1) in a dose-dependent manner, while BrMC cooperated with sorafenib to strengthen this inhibition. Moreover, the combination of sorafenib and BrMC led to a remarkable decrease in the cellular migration and invasion, the downregulation of N-cadherin protein and upregulation of E-cadherin protein, and increase of cell apoptosis in LCSLCs. BrMC has a remarkable antagonistic effect on the upregulation of protein expression and DNA binding activity of NF-κB (p65) induced by sorafenib. In addition, our results indicated that the synergistic inhibition of sorafenib and BrMC on the characteristics of LCSLCs involves the downregulated expression of HIF-1α and EMT regulator Twist1. Collectively, the combination therapy of sorafenib and BrMC could be a new and promising therapeutic approach in the treatment of HCC.

Abstract
Rapid tumor growth creates a state of hypoxia in the tumor microenvironment and results in release of hypoxia inducible factor-1 alpha (HiF-1α) in the local milieu. Hypoxia inducible factor activity is deregulated in many human cancers, especially those that are highly hypoxic. In multiple myeloma (MM) in initial stages of disease establishment, the hypoxic bone marrow microenvironment supports the initial survival and growth of the myeloma cells. Hypoxic tumour cells are usually resistant to radiotherapy and most conventional chemotherapeutic agents, rendering them highly aggressive and metastatic. Therefore, HIF is an attractive, although challenging, therapeutic target in MM directly or indirectly in recent years.

Abstract
BACKGROUND Transcription factor prospero homeobox 1 (PROX1) has been identified as a master regulator of lymphangiogenesis associated with metastasis. Although PROX1 expression has been investigated in several cancers, its clinical significance remains controversial and needs further validation. In this study, we investigated the clinical and functional significance of PROX1 and PROX1 regulator hypoxia-inducible factor 1α (HIF1α) in esophageal squamous cell carcinoma (ESCC). METHODS A total of 117 samples from ESCC patients were analyzed for PROX1, HIF1α, and E-cadherin expression by immunohistochemistry; correlation with clinicopathological characteristics was determined. PROX1 function was evaluated in PROX1 small interfering RNA (siRNA)-transfected human ESCC cells in vitro by assessing cell proliferation and migration. RESULTS PROX1 expression was higher in ESCC than in normal tissues. Patients with higher PROX1 expression (n = 26) had increased nuclear accumulation of HIF1α (p = 0.004) and more advanced metastasis, both lymph node (N factor; p = 0.09) and hematogenous (M factor; p = 0.04), than those with lower PROX1 expression (n = 91). In addition, high PROX1 and HIF1α expression correlated with low levels of E-cadherin, an epithelial cell marker. Analysis of overall and cancer-specific survival indicated that elevated PROX1 expression was significantly correlated with poor prognosis (p = 0.0064). PROX1 downregulation in ESCC cells inhibited cellular proliferation and migration (p < 0.05). Hypoxia restored PROX1 levels that were reduced by PROX1-specific siRNA. CONCLUSION Our data suggest that high expression of PROX1 in ESCC could be used as an indicator of poor prognosis, and that PROX1 is a promising candidate molecular target for ESCC treatment.

Abstract
The aim of the present study was to determine whether the expression of hypoxia-inducible factor-1α (HIF-1α), carbonic anhydrase-IX (CA-IX), glucose transporter-1 (GLUT-1) or vascular endothelial growth factor (VEGF) was associated with the clinicopathological characteristics, lymph node metastasis or progression-free survival of patients with cervical cancer. Tumor tissue samples were obtained from 54 cervical cancer patients who had undergone radical hysterectomy. The expression of HIF-1α, CA-IX, GLUT-1 and VEGF was analyzed by immunohistochemical staining. Of the 54 cases, 28 were positive for HIF-1α, 35 for CA-IX, 40 for GLUT-1 and 23 for VEGF. It was revealed that HIF-1α expression was correlated with tumor stage and histology, CA-IX expression with tumor stage, tumor size, lymph node metastasis and lymph-vascular space involvement, GLUT-1 expression with tumor stage and lymph-vascular space involvement, and VEGF expression with microvessel density. The multivariate regression analysis indicated that CA-IX expression and lymph-vascular space involvement were independent variables associated with lymph node metastasis. Progression-free survival was shorter for patients who were positive for CA-IX or VEGF expression than for those who were negative for CA-IX or VEGF expression. The progression-free survival of patients treated with radiotherapy or chemo-radiotherapy following radical hysterectomy was also shorter for patients with positive CA-IX expression. These findings suggest that CA-IX expression is a possible risk factor for lymph node metastasis and disease recurrence in locally advanced cervical cancer patients.

Celastrol stimulates hypoxia-inducible factor-1 activity in tumor cells by initiating the ROS/Akt/p70S6K signaling pathway and enhancing hypoxia-inducible factor-1α protein synthesis. PLoS One 2014; 9:e112470.

Abstract
Celastrol, a tripterine derived from the traditional Chinese medicine plant Tripterygium wilfordii Hook F. (“Thunder of God Vine”), has been reported to have multiple effects, such as anti-inflammation, suppression of tumor angiogenesis, inhibition of tumor growth, induction of apoptosis and protection of cells against human neurodegenerative diseases. However, the mechanisms that underlie these functions are not well defined. In this study, we reported for the first time that Celastrol could induce HIF-1α protein accumulation in multiple cancer cell lines in an oxygen-independent manner and that the enhanced HIF-1α protein entered the nucleus and promoted the transcription of the HIF-1 target genes VEGF and Glut-1. Celastrol did not influence HIF-1α transcription. Instead, Celastrol induced the accumulation of the HIF-1α protein by inducing ROS and activating Akt/p70S6K signaling to promote HIF-1α translation. In addition, we found that the activation of Akt by Celastrol was transient. With increased exposure time, inhibition of Hsp90 chaperone function by Celastrol led to the subsequent depletion of the Akt protein and thus to the suppression of Akt activity. Moreover, in HepG2 cells, the accumulation of HIF-1α increased the expression of BNIP3, which induced autophagy. However, HIF-1α and BNIP3 did not influence the cytotoxicity of Celastrol because the main mechanism by which Celastrol kills cancer cells is through stimulating ROS-mediated JNK activation and inducing apoptosis. Furthermore, our data showed that the dose required for Celastrol to induce HIF-1α protein accumulation and enhance HIF-1α transcriptional activation was below its cytotoxic threshold. A cytotoxic dose of Celastrol for cancer cells did not display cytotoxicity in LO2 normal human liver cells, which indicated that the novel functions of Celastrol in regulating HIF-1 signaling and inducing autophagy might be used in new applications, such as in anti-inflammation and protection of cells against human neurodegenerative diseases. Future studies regarding these applications are required.

Abstract
PURPOSE Hypoxia is a common phenomenon encountered in solid cancers, leading to chemotherapy resistance and therefore to aggressiveness of the disease. The homeostatic response to hypoxia is mediated by hypoxiainducible factor-1 (HIF-1). The aim of this study was to investigate the impact of HIF1α in patients with primary epithelial ovarian cancer. METHODS In this multicentric study, 275 patients with advanced primary epithelial ovarian cancer were included. All patients underwent cytoreductive surgery with maximal surgical effort and adjuvant platinum-based chemotherapy. HIF1α expression was analyzed in tissue lysates, using an enzyme-linked immunosorbent assay. RESULTS HIF1α was detected in 79.3% of the tissue samples. Patients with increased HIF1α expression (cutoff: 80 pg/mg protein) in tumoral tissue lysates were more likely to have less favorable survival. HIF1α (P=0.009, hazard ratio [HR] 2.505, 95% confidence interval [95% CI] 1.252-5.013) together with International Federation of Gynecology and Obstetrics (III versus IV) (P=0.013, HR 0.540, 95% CI 0.332-0.878), histology (P=0.007, HR 2.748, 95% CI 1.315-5.743), presence of peritoneal carcinomatosis (P=0.014, HR 2.176, 95% CI 1.170-4.046), residual tumor mass (P=0.017, HR 1.641, 95% CI 1.091-2.468), and response to platinum-based chemotherapy (P<0.001, HR 8.131, 95% CI 5.13-12.88) were independent prognosis factors for overall survival. The independent prognostic factors for progression-free survival were International Federation of Gynecology and Obstetrics stage (P=0.01), histological subtypes (P=0.016), and presence of peritoneal carcinomatosis (P<0.05). CONCLUSION HIF1α overexpression in ovarian cancer is associated with poor overall survival, underlining the importance of hypoxia in this angiogenesis driven disease.

Abstract
The expression of hypoxia-induced factor (HIF)-1α is up-regulated in tumor microenvironments under hypoxia condition. However, the prognostic significance of HIF-1α in esophageal squamous cell carcinoma (ESCC) is still elusive. We measured the HIF-1α expression by immunochemistry in tumor specimens from 136 resected ESCC; in the current study, the HIF-1α expression in tumor cells was significantly associated with tumor stage (P = 0.003) and lymph node metastasis (P = 0.006); whereas the HIF-1α expression in tumor-infiltrating lymphocytes (TILs) had no relationship with patients' clinicopathological parameters. Patients with high HIF-1α expression in tumor cells or in TILs showed worse survival related to those with low HIF-1α expression. Multivariate analysis demonstrated that expression of HIF-1α in TILs was an independent factor for DFS (P = 0.007) and OS (P = 0.013). Additionally, the expression of HIF-1α in tumor cells was an independent factor for DFS (P = 0.037) and OS (P = 0.033) in locoregional ESCC patients, whereas the expression of HIF-1α in TILs was an independent factor for DFS (P = 0.048) and OS (P = 0.039) in metastatic ESCC patients. Correlation analysis revealed that expressions of HIF-1α in tumor cells and in TILs were positively correlated, and patients with combined high HIF-1α in both tumor cells and TILs had the worst survivals (P < 0.05). These findings suggest that the HIF-1α expressions in different cell populations of ESCC microenvironments have different clinical relevance and prognostic impact on patients.

Abstract
OBJECTIVES To explore the expression patterns of Eag1 (ether á go-go 1) and HIF-1α (hypoxia-inducible factor 1α) in a cohort of patients with breast cancer. SETTING Department of general surgery in an upper first-class hospital in Xi'an, China. PARTICIPANTS A total of 112 female Han Chinese patients with a diagnosis of invasive ductal carcinoma were included. Patients with main internal diseases, such as cardiovascular, endocrine, gastroenterological, haematological, infectious diseases, etc, were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES Expression profiles of Eag1 and HIF-1α. RESULTS Eag1 and HIF-1α were overexpressed in the tumour tissues compared with the pair-matched control tissues, p=0.002 and <0.001, respectively. The expression of Eag1 and HIF-1α was negatively correlated with tumour size, p=0.032 and p=0.025, respectively, and lymph node status (p=0.040, p=0.032, respectively). The coexpression of Eag1 and HIF-1α was correlated with tumour size (p=0.012), lymph node status (p=0.027) and tumour stage (p=0.036). HIF-1α has a strong correlation with hEag1 expression (κ=0.731, p<0.001). CONCLUSIONS HIF-1α expression has a strong correlation with hEag1 expression. We are the first to attempt to explore the correlation at the population level.

Abstract
Cancer is the second cause of mortality worldwide, primarily owing to failure to cure metastatic disease. The need to target the metastatic process to reduce mortality is clear and research over the past decade has shown hypoxia-inducible factor-1 (HIF-1) to be one of the promising targets. In order for metastatic disease to be established, multiple steps need to be taken whereby the tumour cells escape into the bloodstream and survive, disseminate and then establish at a premetastatic niche. HIF-1 mediates hypoxia-induced proangiogenic factors such as vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), which promote extravasation and chemotaxis. The migration of tumour cells is mediated by loss of E-cadherin, which results in a more invasive phenotype; dissemination of the tumour cells by increased vascular permeability and survival in the bloodstream through resistance to apoptosis as well as adhesion at the premetastatic niche are all controlled by factors under the influence of HIF-1. The overexpression of HIF in many aggressive cancer types as well as its role in the establishment of metastatic disease and treatment resistance demonstrate its potential target in therapeutics. Taken together, the role of HIF-1 in cancer and metastatic disease is clear and the need for better treatment targeting metastases is paramount; more aggressive phenotypes with less response to treatment are associated with HIF-1 expression. Our research has shown promise but many questions still remain to be answered.

Abstract
Lung adenocarcinoma (AC) is one of the most deadly malignancies. The disease has a low five-year survival rate; therefore, the identification of novel therapeutic agents is required. This study aimed to investigate the effect of small interfering RNA (siRNA) targeting hypoxia‑inducible factor 1α (HIF‑1α) on the growth of AC A549 cells. A549 cells were transfected with various concentrations of HIF‑1α or control siRNA, and the effect on HIF‑1α expression was analyzed using quantitative polymerase chain reaction and western blot analysis. The effects of HIF-1α siRNA on growth inhibition and apoptosis were then assessed using standard methods. HIF‑1α siRNA treatment significantly reduced HIF‑1α mRNA and protein expression in A549 cells. Furthermore, the downregulation of HIF-1α expression inhibited the growth of A549 cells and induced apoptosis of A549 cells by upregulating caspase-3 expression. The present in vitro study demonstrates that the downregulation of HIF‑1α is capable of suppressing AC A549 cell growth, through the induction of apoptosis. This suggests that HIF‑1α inhibition may represent a promising strategy for the treatment of AC.

Abstract
Hypoxia-inducible factor (HIF) plays an important role in renal cell carcinoma (RCC) associated with angiogenesis. Factor-inhibiting HIF (FIH), which is the upstream mediator protein of HIF, is receiving more attention today. In the present study, the role of FIH expression in high-risk locally advanced renal cell carcinoma (LARCC) was explored. Eighty-eight high-risk LARCC cases were divided into two groups based on their prognosis. Using immunohistochemical staining, the correlations of FIH expression along with clinicopathological factors, progression-free survival (PFS), and overall survival (OS) were analyzed. FIH was mainly located in the cytoplasm (34/88) and nucleus (31/88) of the renal tumor cell. Nuclear negative expression or cytoplasmic positive expression of FIH were associated with an increased risk of disease progression (p = 0.007 and p < 0.001, respectively) and worse OS (p = 0.020 and p = 0.008, respectively). Using the group with nuclear and cytoplasmic FIH negative expression as reference, further stratified analysis found that the exclusive nuclear FIH expression group had a better PFS and OS [hazard ratio (HR) = 0.153, p = 0.07 and HR = 0, p = 0.961, respectively], and the exclusive cytoplasmic FIH positive group experienced the worst PFS and OS (HR = 2.876, p = 0.005 and HR = 2.799, p = 0.034, respectively). In addition, nuclear negative expression of FIH was associated with a significant negative predictive value for the effect of interferon-alpha (IFN-α) on PFS (p = 0.045). The nuclear negative and cytoplasmic positive expressions of FIH were identified not only as risk factors for disease progression in high-risk LARCC postoperative patients, but also to be associated with poor OS. Furthermore, the nuclear negative expression of FIH may be a promising biomarker for postoperative adjuvant therapy.

Abstract
The effect of hypoxia inducible factor-1alpha (HIF-1alpha) on vascular endothelial growth factor C (VEGF-C) and the correlation between HIF-1alpha and lymphangiogenesis and lymph nodes metastases (LNM) in pancreatic cancer were investigated. Immunohistochemical SP method was used to detect the protein expression of HIF-1alpha and VEGF-C, and Lymphatic vessel density (LVD) was determined by stain of VEGFR-3, collagen type IV in 75 pancreatic head cancers from regional pancreatectomy (RP) during Dec. 2001 to Dec. 2003. The relationship between HIF-1alpha and VEGF-C, lymphangiogenesis, LNM was analyzed statistically. The results showed that the positive expressionrate of HIF-1alpha and VEGF-C in pancreatic cancer tissues was 48.00 % (36/75) and 65.33 % (49/75) respectively. In positive group of HIF-1alpha, the positive rate of VEGF-C and LVD, and LVD rate was 80.56 % (29/36), 13.22+/-3.76 and 88.89 % (32/36) respectively, and in negative group of HIF-1alpha, positive rate of VEGF-C and LVD was 51.28 % (20/39), 5.98+/-2.17 and 66.67 % (26/39) respectively (P<0.01 or P<0.05). It was suggested that HIF-1alpha could promote the expression of VEGF-C, lymphangiogenesis and LNM in pancreatic cancer.

Abstract
Hypoxia and lymphangiogenesis are closely related processes that play a pivotal role in tumor invasion and metastasis. Intratumoral hypoxia is exacerbated as a result of oxygen consumption by rapidly proliferating tumor cells, insufficient blood supply and poor lymph drainage. Hypoxia induces functional responses in lymphatic endothelial cells (LECs), including cell proliferation and migration. Multiple factors (e.g., ET-1, AP-1, C/EBP-δ, EGR-1, NF-κB, and MIF) are involved in the events of hypoxia-induced lymphangiogenesis. Among them, HIF-1α is known to be the master regulator of cellular oxygen homeostasis, mediating transcriptional activation of lymphangiogenesis via regulation of signaling cascades like VEGF-A/-C/-D, TGF-β and Prox-1 in experimental and human tumors. Although the underlying molecular mechanisms remain incompletely elucidated, the investigation of lymphangiogenesis in hypoxic conditions may provide insight into potential therapeutic targets for lymphatic metastasis.

Abstract
Many biomarkers have been identified to be new targeted drugs for lung cancer treatment. Their clinical outcomes are determined by their status mainly evaluated from primary cancer tissues. However, metastasis is the leading cause of death in cancer patients. It is unclear whether their status in primary cancers is similar to that in corresponding metastases. Therefore, we aimed to evaluate similarities or differences for the selected biomarker expression between primary lung cancers and matched metastases and to provide evidence for further using these targets in metastatic tumors from lung cancer. Eleven patients who had received resection of paired tissues of primary lung cancers and matched metastases were collected. The protein expression of VEGF, HIF-1α, Met, P53, TGF-β1, Cox-2 and TNF-α between paired tumors was detected by immunohistochemistry. The results showed that there was no statistical significance between primary cancers and matched metastases for the expressions of the selected biomarkers. The p values were more than 0.05. The major concordance of the selected biomarkers existed between paired primary and metastatic tumors. However, there were still minor differences. Differences in metastases compared with primary tumors were observed in respective two cases for VEGF, HIF-1α and Met, respective one case for TGF-β1, COX2 and TNFα and three cases for P53. In conclusion, there were major concordance and minor difference for each biomarker between primary lung tumors and corresponding metastases, which may have important implications for the understanding of current metastasis models and treatment of advanced lung cancers.

Abstract
The role of hypoxia-inducible factors-1 alpha (HIF-1α) expression in gastric cancer remains controversial. We performed a systematic review of the literature with meta-analysis. Electronic databases were used to identify published studies before December 1, 2012. Pooled hazard ratio (HR) or odds ratio (OR) with 95 % confidence interval (95 % CI) was used to estimate the strength of the association between HIF-1α expression and survival of gastric cancer patients. Heterogeneity and publication bias were also assessed. Final analysis of 1,268 patients from 9 eligible studies was performed. High HIF-1α expression was significantly correlated with poor overall survival (OS) of gastric cancer patients (HR = 2.14, 95 % CI = 1.32-3.48). Subgroup analysis indicated that HIF-1α over-expression had an unfavorable impact on OS in Asian patients (HR = 2.35, 95 % CI = 1.41-3.92). Moreover, up-regulation of HIF-1α was significantly associated with the depth of invasion (OR = 2.49, 95 % CI = 1.28-4.83), lymph node metastasis (OR = 2.15, 95 % CI = 1.27-3.66), and vascular invasion (OR = 2.23, 95 % CI = 1.20-4.14). HIF-1α expression might be a predicative factor of poor prognosis for gastric cancer particularly in Asia.

Abstract
To investigate the correlation of hypoxia-inducible factor-1α (HIF-1α) expression with clinical prognosis and efficacy of radiochemotherapy in esophageal squamous cell carcinoma (ESCC). Studies assessing the clinical or prognostic significance of HIF-1α expression in ESCC published prior to December 2011 were selected by searching PubMed, EMBASE, Cochrane Library, and (China National Knowledge Infrastructure) CNKI. A meta-analysis was performed to clarify the impact of HIF-1α expression on clinicopathological parameters or survival in ESCC. A total of 16 studies met the inclusion criteria, which included 1261 patients with ESCC. Accordingly, the level of HIF-1α expression in esophageal tissues of patients with ESCC was significantly higher than that in normal patients (odds ratio, OR = 33.111, 95 % confidence interval, CI = 11.912-92.040). The expression of HIF-1α correlated with the depth of invasion (OR = 1.701, 95 % CI = 1.076-4.705), clinical TNM stage (OR = 2.160, 95%CI = 1.516-3.077), as well as lymph node metastasis (OR = 2.393, 95 % CI = 1.319-4.344), regardless of differentiation grading (OR = 1.185, 95 % CI = 0.859-1.635). Furthermore, there was a significant association of increased HIF-1α expression with poorer radiochemotherapy outcomes, 2-year overall survival (OR = 0.219, 95 % CI = 0.104-0.461) and survival (OR = 0.320, 95 % CI = 0.115-0.887, P < 0.05) in patients with ESCC. In addition, HIF-1α expression correlated with VEGF expression in the ESCCs (OR = 4.635, 95%CI = 2.591-8.292). Increased expression of HIF-1α plays an important role in the malignant biology of ESCC resulting in significantly poorer radiochemotherapy outcomes and 2-year overall survival. HIF-1α expression may be a prognostic factor, as well as a potential target for therapy in patients with ESCC.

Abstract
Hypoxia-inducible factor-1alpha (HIF-1 alpha) plays an essential role in the regulation of various genes associated with low oxygen consumption. Elevated expression of HIF-1alpha has been reported to be associated with tumor progression, invasion and metastasis in many cancers. To investigate the role of HIF-1alpha in tumor development and metastasis, we established transgenic mice constitutively expressing HIF1A gene under regulation of the cytomegalovirus gene promoter. Although HIF-1alpha protein levels varied among organs, expression of HIF1A mRNA in most organs gradually increased in an age-dependent manner. The transgenic mice showed no gross morphological abnormality up to 8 weeks after birth, although they subsequently developed tumors in the lymphoid, lung, and breast; the most prominent tumor was lymphoma appearing in the intestinal mucosa and intra-mesenchymal tissues. The prevalence of tumors reached 80% in 13 months after birth. The constitution of lymphocyte populations in the transgenic mice did not differ from that in wild-type mice. However, lymphocytes of the transgenic mice revealed prolonged survival under long-term culture conditions and revealed increased resistance to cytotoxic etoposide. These results suggest that HIF-1alpha itself is not oncogenic but it may play an important role in lymphomagenesis mediated through the prolonged survival of lymphocytes in this transgenic mouse model.
