Abstract
Cancer is one of the leading causes of mortality and morbidity worldwide, affecting millions of people physically and financially every year. Over time, many anticancer treatments have been proposed and studied, including synthetic compound consumption, surgical procedures, or grueling chemotherapy. Although these treatments have improved the daily life quality of patients and increased their survival rate and life expectancy, they have also shown significant drawbacks, including staggering costs, multiple side effects, and difficulty in compliance and adherence to treatment. Therefore, natural compounds have been considered a possible key to overcoming these problems in recent years, and thorough research has been done to assess their effectiveness. In these studies, scientists have discovered a meaningful interaction between several natural materials and signal transducer and activator of transcription 3 molecules. STAT3 is a transcriptional protein that is vital for cell growth and survival. Mechanistic studies have established that activated STAT3 can increase cancer cell proliferation and invasion while reducing anticancer immunity. Thus, inhibiting STAT3 signaling by natural compounds has become one of the favorite research topics and an attractive target for developing novel cancer treatments. In the present article, we intend to comprehensively review the latest knowledge about the effects of various organic compounds on inhibiting the STAT3 signaling pathway to cure different cancer diseases.

Comparative efficacy of various CHIs combined with western medicine for non-small cell lung cancer: A bayesian network meta-analysis of randomized controlled trials. Front Pharmacol 2022; 13:1037620. [PMID: 36438813 PMCID: PMC9686447 DOI: 10.3389/fphar.2022.1037620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2022] [Accepted: 10/20/2022] [Indexed: 11/11/2022] Open
Abstract
Background: Given the limitations of Western medicine (WM) for the treatment of non-small cell lung cancer (NSCLC) and the wide exploration of Chinese herbal injections (CHIs), systematically evaluate the efficacy of Various CHIs Combined with WM for Non-small Cell Lung Cancer. In this study, we performed a network meta-analysis to evaluate the comparative efficacy of 16 CHIs combined with WM regimens for the treatment of NSCLC. Methods: Literature databases were searched from their inception to November 2021, and all randomized control trials (RCTs) involving NSCLC patients treated with a combination of Chinese and WM were retrieved. Outcomes, including disease control rate, survival quality score, incidence of gastrointestinal adverse reactions, incidence of leukopenia, and incidence of thrombocytopenia, were analyzed using RevMan (5.3), Stata17, and R software. Surface under the cumulative ranking curve (SUCRA) probability values were calculated to rank the treatments examined, and clustering analysis was used to compare the effects of CHIs on different outcomes. Results: A total of 389 studies involving 31,263 patients and 16 CHIs were included. The 16 CHIs were: Aidi injection (ADI), Huachansu injection (HCSI), oil of Ophiopogon injection (OOMI), disodium cantharidinate and vitamin B6 injection (DCI), Shenfu injection (SFI), Shenmai injection (SMI), Shenqi Fuzheng injection (SQFZI), Chansu injection (CSI), Delisheng injection (DLSI), Fufang Kushen injection (FFKSI), Huangqi injection (HQI), Kangai injection (KAI), Kanglaite injection (KLTI), Shengmai injection (SI), Xiangguduotang injection (XGDTI), and Xiaoaiping injection (XAPI). The results of the network meta-analysis showed that, with WM treatment as a co-intervention, CSI was most likely to improve the disease control rate (SUCRA = 80.90%), HQI had the highest probability of being the best option for improving the survival quality score (SUCRA = 82.60%), DCI had the highest probability of reducing the incidence of gastrointestinal adverse reactions (SUCRA = 85.50%), HCSI + WM had the highest probability of reducing the incidence of thrombocytopenia (SUCRA = 91.30%), while SMI had the highest probability of reducing the incidence of leukopenia (SUCRA = 79.10%). Conclusion: CHIs combined with WM is proved to be more effective than WM alone, which may be beneficial to NSCLC patients. SMI + WM and DCI + WM are most likely the optimal CHI to improve disease control rates, survival quality score, and reduce adverse effects. This study has limitations; therefore, higher quality RCTs and real-world evidence are required to support our conclusions.

Abstract
Clinical data show that the incidence and mortality rates of cancer are rising continuously, and cancer has become an ongoing public health challenge worldwide. Excitingly, the extensive clinical application of traditional Chinese medicine may suggest a new direction to combat cancer, and the therapeutic effects of active ingredients from Chinese herbal medicine on cancer are now being widely studied in the medical community. As a traditional anticancer Chinese medicine, ChanSu has been clinically applied since the 1980s and has achieved excellent antitumor efficacy. Meanwhile, the ChanSu active components (e.g., telocinobufagin, bufotalin, bufalin, cinobufotalin, and cinobufagin) exert great antitumor activity in many cancers, such as breast cancer, colorectal cancer, hepatocellular carcinoma and esophageal squamous cell carcinoma. Many pharmaceutical scientists have investigated the anticancer mechanisms of ChanSu or the ChanSu active components and obtained certain research progress. This article reviews the research progress and antitumor mechanisms of ChanSu active components and proposes that multiple active components of ChanSu may be potential anticancer drugs.

[PMID: 31824138 PMCID: PMC6900468 DOI: 10.2147/dddt.s224312] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 10/22/2019] [Indexed: 12/13/2022]
Abstract
Background Current clinical treatments for osteosarcoma are limited by disease recurrence and primary or secondary chemoresistance. Cancer stem-like cells have been proposed to facilitate the initiation, progression, recurrence and chemoresistance of osteosarcoma. Furthermore, previous studies have reported that IL-6-STAT3 pathway is overexpressed in various types of cancer and contributes to cell proliferation, apoptosis, invasion/migration, chemoresistance and modulation of stemness features. Aim To examined the effect of cinobufagin on cancer progression and modulation of stemness features in osteosarcoma, and investigated the molecular mechanisms underlying such effects. Methods Human osteosarcoma cell lines U2OS/MG-63 were recruited in this study. Cell proliferation, migration, and invasion were determined by MTT assay, colony formation assay,wound healing assay, and cell invasion assay respectively. Its effect on stemness was assessed by flow cytometry and mammosphere formation. The protein expression levels of related proteins were detected by Western blot. The xenograft model, immunofluorescence staining and immunohistochemistry were used to determine the effect of cinobufagin on tumorigenicity in vivo experiment. Results We found that cinobufagin suppressed the viability of U2OS/MG-63 spheroids/parent cells in a time-and dose-dependent manner. Notably, cinobufagin had no effect on the viability of hFOB 1.19 cells. Moreover, cinobufagin induced apoptosis, increased the width of wounds, reduced invasive osteosarcoma spheroids/parent cell numbers and reduced EMT phenotype and OPN levels in U2OS/MG-63 spheroids as well as U2OS/MG-63 parent cells lines. Noticeablely, we found that OPN levels were higher in spheroids group than that in parent cells. In addition, cinobufagin ameliorated the proportion of CD133-positive cells, the size of spheroids and Nanog, Sox-2 and Oct3/4 protein levels. Our in vivo experiments showed that cinobufagin consistently reduced tumor volume,the expressions of OPN, Sox-2, Oct3/4, Nanog and p-STAT3 by the immuno histochemistry staining as well as CD133 expression in tumor tissues by immunofluorescence analysis. From a mechanistic point of view, cinobufagin was shown to inhibit IL-6-OPN-STAT3 signaling pathway. Exogenous IL-6/OE-OPN/overexpression STAT3 attenuated the induction of cinobufagin-mediated apoptosis and the suppression of stemness properties respectively. Conclusion Collectively, our data demonstrated that cinobufagin inhibited the viability and tumorigenesis capability of osteosarcoma cells by blocking IL-6- OPN-STAT3 signaling pathway. Cinobufagin may therefore represent a promising therapeutic agent for osteosarcoma management. ![]()

The Potential Mechanism of Bufadienolide-Like Chemicals on Breast Cancer via Bioinformatics Analysis. Cancers (Basel) 2019; 11:cancers11010091. [PMID: 30646630 PMCID: PMC6357202 DOI: 10.3390/cancers11010091] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/20/2018] [Accepted: 01/08/2019] [Indexed: 12/31/2022] Open
Abstract
Bufadienolide-like chemicals are mostly composed of the active ingredient of Chansu and they have anti-inflammatory, tumor-suppressing, and anti-pain activities; however, their mechanism is unclear. This work used bioinformatics analysis to study this mechanism via gene expression profiles of bufadienolide-like chemicals: (1) Differentially expressed gene identification combined with gene set variation analysis, (2) similar small -molecule detection, (3) tissue-specific co-expression network construction, (4) differentially regulated sub-networks related to breast cancer phenome, (5) differentially regulated sub-networks with potential cardiotoxicity, and (6) hub gene selection and their relation to survival probability. The results indicated that bufadienolide-like chemicals usually had the same target as valproic acid and estradiol, etc. They could disturb the pathways in RNA splicing, the apoptotic process, cell migration, extracellular matrix organization, adherens junction organization, synaptic transmission, Wnt signaling, AK-STAT signaling, BMP signaling pathway, and protein folding. We also investigated the potential cardiotoxicity and found a dysregulated subnetwork related to membrane depolarization during action potential, retinoic acid receptor binding, GABA receptor binding, positive regulation of nuclear division, negative regulation of viral genome replication, and negative regulation of the viral life cycle. These may play important roles in the cardiotoxicity of bufadienolide-like chemicals. The results may highlight the potential anticancer mechanism and cardiotoxicity of Chansu, and could also explain the ability of bufadienolide-like chemicals to be used as hormones and anticancer and vasoprotectives agents.

Bufalin suppresses hepatocarcinogenesis by targeting β-catenin/TCF signaling via cell cycle-related kinase. Sci Rep 2018; 8:3891.

Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive malignant tumors, of which treatment options are limited especially in advanced stage. Bufalin, the major digoxin-like component of the traditional Chinese medicine Chansu, exhibits significant antitumor activities in hepatoma cells, but the potential mechanism is obscure. Cell cycle-related kinase (CCRK) is recently identified to be a crucial oncogenic master regulator to drive hepatocarcinogenesis. Here we investigated the molecular function of bufalin on CCRK-regulated signaling pathway, and expounded the underlying mechanism in HCC suppression. In vitro with PLC5 HCC cells and human immortal LO2 cells, proliferation, malignant transformation and cell cycle progression assays were performed to evaluate the antitumor effect of bufalin. In vivo with xenograft and orthotopic mice models, tumor growths with weight and volume change were assessed with or without bufalin treatment. Western blot, RT-qPCR, immunofluorescence and immunohistochemistry were conducted to examine the expression level of CCRK and β-catenin/TCF signaling cascade. We revealed that bufalin suppresses PLC5 HCC cell proliferation, transformation and cell cycle progression rather than LO2 cells, which is correlated with CCRK-mediated β-catenin/TCF signaling. It was also confirmed in mice model. Thus, bufalin is a potential anti-HCC therapeutic candidate through the inhibition of CCRK-driven β-catenin/TCF oncogenic signaling pathway.

Abstract
The cinobufagin (CB) has a broad spectrum of cytotoxicity to inhibit cell proliferation of various human cancer cell lines, but the molecular mechanisms still remain elusive. Here we observed that CB inhibited the cell proliferation and tumor growth, but induced cell cycle arrest and apoptosis in a dose-dependent manner in non-small cell lung cancer (NSCLC) cells. Treatment with CB significantly increased the reactive oxygen species but decreased the mitochondrial membrane potential in NSCLC cells. These effects were markedly blocked when the cells were pretreated with N-acetylcysteine, a specific reactive oxygen species inhibitor. Furthermore, treatment with CB induced the expression of BAX but reduced that of BCL-2, BCL-XL and MCL-1, leading to an activation of caspase-3, chromatin condensation and DNA degradation in order to induce programmed cell death in NSCLC cells. In addition, treatment with CB reduced the expressions of p-AKTT308 and p-AKTS473 and inhibited the AKT/mTOR signaling pathway in NSCLC cells in a time-dependent manner. Our results suggest that CB inhibits tumor growth by inducing intrinsic apoptosis through the AKT signaling pathway in NSCLC cells.

Abstract
Cinobufacini, a traditional Chinese medicine, has been used widely for cancer treatment, such as hepatocellular carcinoma (HCC), sarcoma, and leukemia. Previous studies done by our lab indicated that cinobufacini could suppress HCC cells through mitochondria-mediated and Fas-mediated apoptotic pathways. Here, we use a combination of cinobufacini and doxorubicin to inhibit the growth of HCC cells. The combination group induced more significant apoptosis by affecting proteins and RNA of apoptosis-related elements, such as Bcl-2, Bax, Bid, and cytochrome c. Furthermore, cinobufacini, as a mixture of a number of components, had stronger apoptosis-inducing activity than particular individual components or a simple mixture of a few components. Overall, these results suggested that the combination of cinobufacini and doxorubicin may provide a new strategy for inhibiting the proliferation of HCC cells.

Abstract
Statistical analyses of high-performance liquid chromatography (HPLC)-based chemical fingerprints of Bufo bufo gargarizans toad skin extracts were integrated with antitumor evaluations as a means to more effectively identify bioactive constituents. Specifically, chemical fingerprints of Bufo bufo gargarizans skin extract samples obtained from ten different regions in China were generated by HPLC, and then subjected to similarity analysis and principal component analysis (PCA). Concurrently, a MCF-7 breast cancer cell model was adopted to obtain the antitumor activity of different toad skin extracts. The chromatographic fingerprint-bioactivity relationships of the Bufo bufo gargarizans extracts were then evaluated by Pearson correlation analysis. The results demonstrated that all skin extract samples inhibited the proliferation of MCF-7 cells to some extent, and that there was a correlation between the chemical fingerprints and the anti-proliferative activity. Bufotalin, bufalin, and cinobufagin, three known components of Bufo bufo gargarizans that were identified in the chemical fingerprints, were highlighted as constituents responsible for the observed bioactivity. The activity of cinobufagin was confirmed by cell viability and colony formation assays using MCF-7 cells. The approach documented here provides a more effective means to associate chemical information on medicinal extracts with the principle components responsible for their bioactivity, and to therefore expedite drug discovery.

[PMID: 27176794 PMCID: PMC4899018 DOI: 10.3892/or.2016.4782] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2016] [Accepted: 03/03/2016] [Indexed: 12/12/2022] Open
Abstract
The main objective of this study was to explore whether autophagy could be triggered by cinobufagin, and to clarify the role of autophagy in the antitumor effects of cinobufagin on U2OS cells and the underlying mechanisms. U2OS cells were exposed to 15, 30, 60 and 120 mg/l cinobufagin for 0, 12, 24 and 48 h. An MTT assay was used to measure cell viability. FITC-Annexin Ⅴ/PI staining and flow cytometry were used to analyze the apoptotic ratio, while apoptotic morphological changes were assessed by PI and Hoechst 33258 viable cell staining. The effects of autophagy on the cells were investigated with GFP-LC3b green fluorescence plasmid transfection and transmission electron microscopy. The levels of caspase-3, -8, - 9, cleaved PARP, LC3-II/LC3-I, p62 and the activation of JNK/p-38 were detected by western blot analysis. Reactive oxygen species (ROS) fluorescence intensity was examined under fluorescence microscopy with an analysis software system. Cell proliferation was obviously inhibited by cinobufagin in a dose- and time-dependent manner. The apoptosis ratio was gradually increased with treatment time as evidenced by flow cytometric analysis and Hoechst 33258 staining. Exposure to cinobufagin resulted in the activation of caspase-3, -8, -9, as well as cleaved PARP which indicated that cinobufagin induced caspase-dependent apoptosis. Autophagy was confirmed in the cinobufagin-treated cells as evidenced by formation of autophagosomes, accumulation of GFP-LC3 fluorescence particles as well as the upregulation of LC3-II/LC3-I levels. Inhibition of autophagy diminished apoptosis as detected by the MTT assays. Moreover the percentage of apoptotic cells decreased following pretreatment with 3-MA, CQ and si-beclin-1. Cinobufagin also induced phosphorylation of the JNK and p38 signaling pathway as well as ROS generation. The JNK and p38 inhibitors significantly attenuated coexistence of apoptosis and autophagy-related proteins. The ROS scavenger also prevented phosphorylation of the JNK and p38 signaling pathway. Our research proved that cinobufagin triggered apoptosis and autophagic cell death via activation of the ROS/JNK/p-38 axis.

Abstract
Traditional Chinese medicine (TCM) has been a major part of healthcare in China, and has extensively affected medicine and healthcare in surrounding countries over a long period of time. In the fight against cancer, certain anticancer remedies using herbs or herbal formulas derived from TCM have been developed for the management of malignancies. Furthermore, there are clinical trials registered for the use of herbal remedies in cancer management. Herbal medicine has been used as part of combined therapies to reduce the side-effects of chemotherapy, including bone marrow suppression, nausea and vomiting. Herbal remedies have also been used as chemopreventive therapies to treat precancerous conditions in order to reduce the incidence of cancer in high-risk populations. Emerging evidence has revealed that herbal remedies can regulate the proliferation, apoptosis, adhesion and migration of cancer cells. In addition to this direct effect upon cancer cells, a number of herbal remedies have been identified to suppress angiogenesis and therefore reduce tumour growth. The inhibition of tumour growth may also be due to modifications of the host immune system by the herbal treatment. However, the precise mechanisms underlying the therapeutic effects of herbal remedies remain poorly understood and are yet to be fully elucidated. The present study aims to summarize the current literature and clinical trial results of herbal remedies for cancer treatment, with a particular focus on the recent findings and development of the Yangzheng Xiaoji capsule.

Abstract
Huachansu (HCS), a hot water extract of the skin glands of Bufo gargarizans (B. melanostictus), has been used extensively in the treatment of various solid tumors in Asia, particularly in China. However, its effect on the growth of malignancies of hematopoietic origin, particularly lymphomas, is limited. Here we investigated the antiproliferative effect and molecular mechanisms of HCS using non-Hodgkin’s lymphoma (NHL) Raji, Ramos, and Namalwa cells and the mantle cell lymphoma cells SP53. HCS inhibited proliferation in these cell lines with an IC50 ranging from 3.1 to 25 μl/ml. At a concentration of 25 μl/ml, HCS triggered a sub-G1 arrest in Ramos cells and induced early to late apoptotic cell death. Cleaved caspase-3 was formed in a concentration-dependent manner in Ramos cells following treatment with HCS for 24 h. Intriguingly, when the Ramos cells were treated with the caspase inhibitor ZDEVD, the apoptotic activity of HCS was partially blocked. Furthermore, HCS also blocked the expression of survivin and pRB proteins in a concentration-dependent manner in Ramos cells. Mechanistically, HCS downregulated both the MAPK gene and proteins in Ramos cells. Collectively, our data suggest that HCS is effective in inducing cell death and apoptosis, in part, by activating caspase-3 activity and suppressing MAP kinase in NHL cells.

Abstract
Objectives: The main objective of this study was to evaluate the anti-depressant effects of pharmacopuncture using sumsu (Bufonis venenum). Methods: Animals were divided into three groups (control, sham, and experimental), with eight mice per group. The sham and the experimental groups were exposed to 2 hours of immobilization stress daily for 14 days. They were also injected with normal saline (sham) or subjected to pharmacopuncture with sumsu at the acupoints HT7, SP6, and GV20 (experimental). The depression or anxiety-like behaviors of the mice in each group were evaluated 1 day after treatment. Results: There was no difference in locomotor activity between the groups during the open-field test; i.e., all groups had normal motor function. However, the open-field and the forced-swimming tests revealed that depression and anxiety-like behaviors were decreased significantly in the group treated with sumsu pharmacopuncture. Conclusion: Sumsu pharmacopuncture attenuated depressive or anxiety-like behavior in mice stressed with chronic immobilization. These results suggest that sumsu pharmacopuncture has therapeutic potential for treating neuropsychiatric disorders such as anxiety or depression disorder.

Abstract
Background Huachansu injection (HCS) is a water-soluble preparation made from Bufo gargarizans’s skin, which has been widely used in clinics for tumor therapy in China. Though the anti-cancer activity of HCS has been verified through studies in vitro and in vivo, there is little research about its potential anti-metastasis effect. The primary objective of this study was to assess the effects of HCS on both the invasion of pancreatic cancer cells in vitro and on the progression of liver metastasis in vivo in this study. Methods HCS anti-metastasis potential was accessed using both assay of Cell viability and invasion in vitro, and then further Establishing xenograft model in nude mice. In the cell-based assay, mRNA and protein expression of MMP-2, MMP-9 and VEGF was detected by semi-quantitative RT-PCR and western blotting. In animal experiment, liver metastasis nodules and change of liver-body ratio was observed. Meanwhile, correlation of the CA19-9 and CEA content in serum with the progression of liver metastasis was analyzed. Result We observed that HCS prevented the invasion of cancer cells, with inhibiting the expressions of MMP-2 and MMP-9, and reduced not only the number of metastasis nodules but the ratio of liver-body weight as well. Furthermore, HCS decreased the expression of MMP-2, MMP-9 and VEGF in liver metastasis, while also reducing CA19-9 contents in serum. In addition, correlation analysis indicated that the level of CA19-9 in serum was closely related to the number of liver metastasis nodules. Conclusion Our experimental results suggest that HCS has some anti-metastasis potential to suppress the growth of liver metastasis by decreasing the expression of MMP-2 and MMP-9 as well as VEGF.

Abstract
To discover and develop novel natural compounds, active ingredients, single herbs and combination formulas or prescriptions in traditional Chinese medicine (TCM) with therapeutic selectivity that can preferentially kill cancer cells and inhibit the amplification of cancer without significant toxicity is an important area in cancer therapy. A lot of valuable TCMs were applied as alternative or complementary medicines in the United States and Europe. But these TCMs, as one of the main natural resources, were widely used to research and develop new drugs in Asia. In TCMs, some specific herbs, animals, minerals and combination formulas were recorded and exploited due to their active ingredients and specific natural compounds with antitumor activities. The article focused on the antitumor properties of natural compounds and combination formulas or prescriptions in TCMs, described its influence on tumor progression, angiogenesis, metastasis, and revealed its mechanisms of antitumor and inhibitory action. Among the nature compounds, triptolide, berberine, matrine, oxymatrine, kurarinone and deoxypodophyllotoxin (DPT) with specific molecular structures have been separated, purified, and evaluated their antitumor properties in vitro and in vivo. Cancer is a multifactorial and multistep disease, so the treatment effect of combination formulas and prescriptions in TCMs involving multi-targets and multi-signal pathways on tumor may be superior than that of agents targeting a single molecular target alone. Shi Quan Da Bu Tang and Yanshu injection, as well known combination formulas and prescriptions in TCMs, have shown an excellent therapeutic effect on cancer.

Abstract
Background: The skin of Bufo bufo gargarizans Cantor, rich in bufadienolides, peptides, and alkaloids, has approved pharmacological activity for preliminary anti-liver and lung tumor treatment. However, few studies have systematically focused on the influence of the producing regions on the content and antitumor activity of the active constituents in toad skins. Objective: This study aims to compare toad skins obtained from six different regions in China (Jiangsu, Anhui, Henan, Hebei, Jiangxi, and Shandong province) for their bufadienolide and alkaloid content, and their cytotoxic activity on two lung carcinoma cell lines (SPC-A-1 cells and A549 cells). Materials and Methods: High performance liquid chromatography (HPLC) was used to quantificationally determine four bufadienolides, which included bufotalin, bufalin, cinobufagin, and resibufogenin in toad skins, from six different regions, respectively. In addition, an ultraviolet (UV) spectrophotometer was also employed to identify the content of the total alkaloids using 5-hydroxytryptamine (5-HT) as the reference substance. An MTT assay was performed to compare the antiproliferative effects of the toad skins’ ethanolic extracts from the different regions against SPC-A-1 and A549 cells. Results: In this study, the toad skins from Jiangsu province had the highest amount of bufadienolides (472.6 μg/g crude drug) and alkaloids (1.51 mg/g crude drug). Meanwhile, according to the extract, it exhibited the strongest cytotoxic effect against the lung carcinoma cell line (SPC-A-1 cells and A549 cells) with IC50 values of 24.82 ± 0.76 and 23.77 ± 0.63 μg crude drug/mL, respectively. Conclusion: The toad skins that originated from the Jiangsu province, have comparatively greater advantages over samples from other regions as far as active constituent content and potential anti-lung cancer activity is concerned, suggesting that it can be a promising chemotherapeutic agent in lung cancer therapy, in further studies.

Abstract
Resibufogenin (RB), a major bioactive bufadienolide, has the potential anticancer activity. In the present work, biotransformation of RB by Actinomucor elegans AS 3.2778 yielded five products, namely 3-oxo-resibufogenin (1), 3-epi-resibufogenin (2), 3-epi-12-oxo-hydroxylresibufogenin (3), 3α-acetoxy-15α-hydroxylbufalin (4), and 3-epi-12α-hydroxylresibufogenin (5), respectively. Among them, metabolites 3 and 4 are previously unreported. The chemical structures of metabolites 1-5 were fully elucidated on the basis of 2D NMR and HR-MS. The highly stereo- and regio-specific isomerization, hydroxylation, and esterification reactions were observed in the biotransformation process of RB by A. elegans. Their cytotoxicities against A549 and H1299 cells were evaluated.

Abstract
Traditional Chinese medicines (TCMs) have played a significant role in the process of discovering natural bioactive compounds, especially in anticancer therapeutics. However, the components of TCMs are complex mixtures with wide variation in polarity and content, which leads to inefficiency in the process of active compound discovery from TCMs. In this paper, the popular strategy of utilizing "pre-fractionated natural product libraries" has been improved by a new class separation approach to accelerate the process. As an example, the skin of Bufo bufo gargarizans Cantor, a well-known TCM, mainly contains two distinct bufadienolide classes: amino acid-conjugated bufadienolides (AACBs) and free form bufadienolides (AAUBs). We utilized hydrophilic interaction liquid chromatography solid-phase extraction (HILIC-SPE) to resolve the two types of bufadienolides, which co-eluted on C18 columns. By this strategy, twelve bufadienolides of the two types were purified via prep-HPLC from one active fraction, and eight of them were identified by (1)H NMR and (13)C NMR. These results indicated that the class separation method not only overcame the limited orthogonality in a 2D-RPLC×RPLC system but also accelerated the process of active compound discovery.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chan Su, an ethanolic extract from skin and parotid venom glands of the Bufo bufo gargarizans Cantor, is widely used as a traditional Chinese medicine for cancer therapy. Although the anti-cancer properties of Chan Su have been investigated, no information exists regarding whether Chan Su has genotoxic effects in cancer cells. The aim of the present study was to examine the cyto-/genotoxic effect of Chan Su in human breast carcinoma (MCF-7 cells), human lung carcinoma (A-549 cells), human T cell leukemia (Jurkat T cells), and normal human lymphocytes. MATERIALS AND METHODS Effects on the viability of MCF-7, A-549, Jurkat T cells, and normal lymphocytes were evaluated by Trypan blue exclusion assays. The DNA content in the sub-G1 region was detected by propidium iodide (PI) staining and flow cytometry. The genotoxicity of Chan Su was assessed by single-cell gel electrophoresis (comet assay) and the cytokinesis-block micronucleus assay (CBMN assay). RESULTS Chan Su significantly inhibited the viability of MCF-7, A-549, and Jurkat T cells dose dependently, but had no effect on normal human lymphocytes. Apoptotic death of the cancer cells was evident after treatment. Chan Su also induced genotoxicity in a dose-dependent manner, as indicated by the comet and cytokinesis-block micronucleus assays. CONCLUSIONS These findings suggest that Chan Su can induce apoptotic death of, and exert genotoxic effects on, MCF-7, A-549, and Jurkat T cells.

Toad glandular secretions and skin extractions as anti-inflammatory and anticancer agents. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2014; 2014:312684. [PMID: 24734105 PMCID: PMC3963377 DOI: 10.1155/2014/312684] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2013] [Revised: 01/10/2014] [Accepted: 01/20/2014] [Indexed: 02/07/2023]
Abstract
Toad glandular secretions and skin extractions contain many natural agents which may provide a unique resource for novel drug development. The dried secretion from the auricular and skin glands of Chinese toad (Bufo bufo gargarizans) is named Chansu, which has been used in Traditional Chinese Medicine (TCM) for treating infection and inflammation for hundreds of years. The sterilized hot water extraction of dried toad skin is named Huachansu (Cinobufacini) which was developed for treating hepatitis B virus (HBV) and several types of cancers. However, the mechanisms of action of Chansu, Huachansu, and their constituents within are not well reported. Existing studies have suggested that their anti-inflammation and anticancer potential were via targeting Nuclear Factor (NF)-κB and its signalling pathways which are crucial hallmarks of inflammation and cancer in various experimental models. Here, we review some current studies of Chansu, Huachansu, and their compounds in terms of their use as both anti-inflammatory and anticancer agents. We also explored the potential use of toad glandular secretions and skin extractions as alternate resources for treating human cancers in combinational therapies.

Cell Death Dis 2014; 5:e1050. [PMID: 24503542 PMCID: PMC3944264 DOI: 10.1038/cddis.2014.4] [Citation(s) in RCA: 118] [Impact Index Per Article: 11.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2013] [Revised: 12/12/2013] [Accepted: 12/13/2013] [Indexed: 12/23/2022]
Abstract
MicroRNAs (miRNAs) are short non-coding RNAs that interfere with translation of specific target mRNAs and thereby regulate diverse biological processes. Recent studies have suggested that miRNAs might have a role in osteoblast differentiation and bone formation. Here, we show that miR-542-3p, a well-characterized tumor suppressor whose downregulation is tightly associated with tumor progression via C-src-related oncogenic pathways, inhibits osteoblast proliferation and differentiation. miRNA array profiling in Medicarpin (a pterocarpan with proven bone-forming effects) induced mice calvarial osteoblast cells and further validation by quantitative real-time PCR revealed that miR-542-3p was downregulated during osteoblast differentiation. Over-expression of miR-542-3p inhibited osteoblast differentiation, whereas inhibition of miR-542-3p function by anti-miR-542-3p promoted expression of osteoblast-specific genes, alkaline phosphatase activity and matrix mineralization. Target prediction analysis tools and experimental validation by luciferase 3′ UTR reporter assay identified BMP-7 (bone morphogenetic protein 7) as a direct target of miR-542-3p. It was seen that over-expression of miR-542-3p leads to repression of BMP-7 and inhibition of BMP-7/PI3K- survivin signaling. This strongly suggests that miR-542-3p suppresses osteogenic differentiation and promotes osteoblast apoptosis by repressing BMP-7 and its downstream signaling. Furthermore, silencing of miR-542-3p led to increased bone formation, bone strength and improved trabecular microarchitecture in sham and ovariectomized (Ovx) mice. Although miR-542-3p is known to be a tumor repressor, we have identified second complementary function of miR-542-3p where it inhibits BMP-7-mediated osteogenesis. Our findings suggest that pharmacological inhibition of miR-542-3p by anti-miR-542-3p could represent a therapeutic strategy for enhancing bone formation in vivo.

Abstract
OBJECTIVE To investigate the effect of Delisheng Injection (, DLS), a Chinese medicinal compound, DLS combined with cis-platinum (DDP), an active agent used in lung cancer chemotherapy, on a human highly metastatic giant lung carcinoma cell line PGCL3. METHODS The suspended PGCL3 cells at 10(5) /mL cultured in 96-well tissue culture plates were divided into 4 groups: DLS treatment group (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL), DDP treatment group (1 μg/mL, 2 μg/mL, 5 μg/mL, 15 μg/mL), combined DLS with DDP treatment group (DLS:DDP 2 μL/mL:1 μg/mL, 5 μL/mL:2 μg/mL, 10 μL/mL:5 μg/mL, 25 μL/mL:15 μg/mL) and a control group. The cytotoxicity of DLS with different concentrations (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL) on PGCL3 cells was determined by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay. Effect of DLS on adhesion of PGCL-3 cells was tested by cell-matrigel adhesion assay. Chemotactic movement model of transwell camerula was used to determine the effect of DLS on invasion and migration of PGCL-3 cells. RESULTS Compared with the control group, DLS (2 μL/mL, 5 μL/mL, 10 μL/mL, 25 μL/mL) could significantly decrease cell proliferation, adhesion, invasion and migration abilities (P <0.05). Cell adhesion, invasion and migration abilities were significantly decreased after combination treatment of DLS:DDP (2 μL/mL:1 μg/mL, 5 μL/mL:2 μg/mL, 10 μL/mL:5 μg/mL, 25 μL/mL:15 μg/mL) compared with DDP single-agent treatment (1 μg/mL, 2 μg/mL, 5 μg/mL, 15 μg/mL, P<0.05), respectively. CONCLUSIONS DLS single-agent has a satisfying inhibition effect in PGCL3 cell line and DLS might enhance the inhibition effect of DDP on cancer metastasis. Our research provided a experimental basis about the treatment on highly metastatic lung caner.

Abstract
Chansu is one of the most widely used traditional Chinese medicines in China, Japan, and other Southeast Asian countries primarily for antipain, anti-inflammation, and recently anticancer. Over 10 recipes and remedies contained Chansu, which are easily available in pharmacies and hospitals, but the mechanisms of action were not clearly articulated. In the present study, Cinobufagin (CBF), the major compound of Chansu, was employed as a surrogate marker to determine its ability in inducing cancer cell death. As expected, CBF has significant cancer-killing capacity for a range of cancers, but such ability differs markedly. Colon and prostate cancers are more sensitive than skin and lung cancers. Interestingly, cancer cells die through apoptotic pathway either being biphasic caspase-3-dependent (HCT116) or independent (HT29). Multipathway analysis reveals that CBF-induced apoptosis is likely modulated by the hypoxia-inducing factor-1 alpha subunit (HIF-1α) as its inhibition was evident in vitro and in vivo. Taken together, these results demonstrate that CBF is a potent apoptotic inducer with potential for further development as a novel and effective anticancer agent for a range of cancers, especially colon cancer.

Abstract
A rapid and validated method was established for the simultaneous determination of eight active and toxic bufadienolides in cinobufacini injection using high performance liquid chromatography coupled with triple quadrupole mass spectrometry. These eight compounds were separated within 3 min on a C(18) analytical column with gradient elution. Eleven batches of cinobufacini injection were analyzed with good linear regression relationship (r, 0.9979-0.9999), precisions (RSD, 1.92-4.79%), repeatability (RSD, 3.12-4.96%), stability (RSD, 2.84-4.45%), and recovery (93.96-104.89%). By using the established method, the present study offered highly sensitive, specific, and speedy determination of eight bufadienolides, which promoted the quality control investigation of cinobufacini injection greatly.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cinobufacini has been traditionally used in China for the treatment of tumor since hundreds years ago. For recent years, its modern preparation,cinobifucini injection has also obtained satisfactory therapeutic functions for cancer. MATERIALS AND METHODS High performance liquid chromatography (HPLC) analysis was applied to determine the content of cinobufagin, resibufogenin and bufothionine in cinobufacin extract liquid and injection; MTT assay and flow cytometric analysis were also respectively used to study the effect of cinobufacini extract liquid, injection and three chemical structures on cells and cell cycles. RESULTS HPLC results demonstrated that in cinobufacini extract liquid three ingredients (cinobufagin, resibufogenin and bufothionine) were all monitored while in cinofacini injection only bufothinone was detected; MTT assays showed bufothionine could obviously inhibit the proliferation of human hepatocellular carcinoma cell lines such as SMMC-7721 and BEL-7402 in a dose- and time-dependent manner as well as cinobufagin and resibufogenin; further flow cytometric analysis indicated obvious increases in G2/M phase and decrease in G0/G1 phase when SMMC-7721 cell line exposure to bufothionine (480 μg/ml). CONCLUSIONS These results suggested bufothionine could be involved in treatment of human cancer for cinobufacini injection and the mechanism might be relative to induce G2/M phase cell cycle arrest.

Abstract
Pycnidione, a small tropolone first isolated from the fermented broth of Theissenia rogersii 92031201, exhibits antitumor activities through an undefined mechanism. The present study evaluated the effects and mechanisms of pycnidione on the growth and death of A549 human lung cancer cells. Pycnidione significantly inhibited the proliferation of A549 cells in a concentration-dependent manner, with a 50% growth inhibition (GI(50)) value of approximately 9.3nM at 48h. Pycnidione significantly decreased the expression of cyclins D1 and E and induced G(1)-phase cell cycle arrest and a subsequent increase in the sub-G(1) phase population. Pycnidione also markedly reduced the expression of survivin and activated caspase-8 and -3, increased reactive oxygen species (ROS) generation, caused the collapse of the mitochondrial membrane potential (MMP), and enhanced PAI-1 production, thus triggering apoptosis in the A549 cells. Taken together, pycnidione exerts anti-proliferative effects on human lung cancer cells through the induction of cell cycle arrest and apoptosis. Therefore, testing of its effects in vivo is warranted to evaluate its potential as a therapeutic agent against lung cancer.

Abstract
Cinobufacini (Huachansu), an aqueous extract from the skins of Bufo bufo gargarizans Cantor, is a well-known traditional Chinese medicine widely used in clinical cancer therapy in China. However, the precise mechanisms induced by cinobufacini in human hepatocellular carcinoma (HCC) cells are still not very clear. The aim of present study was to investigate possible apoptotic mechanisms induced by cinobufacini in HCC cell lines HepG(2) and Bel-7402. We found that cinobufacini treatment resulted in a significant decrease in cell proliferation and induced apoptotic cell death with the increase of treatment time. It indicated that cinobufacini-induced apoptosis was associated with mitochondria-mediated pathway including the loss of mitochondrial membrane potential (Δψm), the increase of Bax/Bcl-2 ratio, cytochrome c release, caspase-9 and caspase-3 activation, and poly(ADP-ribose) polymerase (PARP) degradation. Additionally, cinobufacini also activated Fas-mediated apoptosis pathway obviously as evident by an increase in Fas expression, and caspase-8 and caspase-10 activation. Moreover, the BH3-only protein Bid was cleaved into a truncated Bid (tBid) after cinobufacini treatment. Taken together, these data suggested cinobufacini could induce apoptosis of HCC cells through mitochondria- and Fas-mediated caspase-dependent pathways with the increase of treatment time, which might provide an experimental evidence for cinobufacini treatment of HCC.

Abstract
The biotransformation of three bioactive bufadienolides, namely, bufotalin (1), telocinobufagin (2), and gamabufotalin (3) by cell suspension cultures of Saussurea involucrata yielded 11 products. Bufotalin yielded 3-epi-bufotalin (1a), 3-epi-desacetylbufotalin (1b), 3-epi-bufotalin 3-O-β-D-glucoside (1c), 1β-hydroxybufotalin (1d), and 5β-hydroxybufotalin (1e); telocinobufagin yielded 3-dehydroscillarenin (2a), 3-dehydrobufalin (2b), and 3-epi-telocinobufagin (2c); and gamabufotalin yielded 3-epi-gamabufotalin (3a), 3-dehydrogamabufotalin (3b), and 3-dehydro-Δ¹-gamabufotalin (3c), respectively. Among these 11 products, 1a, 1b, 1c, 1d, 3a and 3c are previously unreported. The structures of these metabolites were elucidated based on NMR spectroscopic analyses and mass spectrometry. Most metabolites showed significant cytotoxic activities against human hepatoma (HepG2) and breast cancer (MCF-7) cell lines. In addition, the time course for the biotransformation of 3 was investigated.

Abstract
The death receptor ligand TRAIL is considered a promising candidate for cancer therapy because of its preferential toxicity to malignant cells. However its efficacy has been challenged by a number of resistance mechanisms. Therefore, agents that can overcome the resistance to enhance therapeutic efficacy of TRAIL are needed. In the current study, we found that bufalin, bufotalin and gamabufotalin, key members of bufadienolides isolated from a traditional Chinese medicine ChanSu, significantly potentiated human breast cancer cells with different status of ER-alpha to apoptosis induction of TRAIL, as evidenced by enhanced Annexin V/FITC positive cells (apoptotic cells), cytoplasmic histone-associated-DNA-fragments, membrane permeability transition (MPT), caspases activation and PARP cleavage. Further mechanistic investigation demonstrated that bufalin was able to significantly decrease Mcl-1 expression and modestly decrease Bcl-XL expression level. Down-regulations of these anti-apoptotic proteins were well correlated with inhibition of transcription factor STAT3 activation. The important consequence of down-regulation Mcl-1 in the enhancement action by combining bufalin with TRAIL was confirmed by either knockdown or overexpression of Mcl-1 approach. Our findings for the first time provided strong evidences that bufadienolide compounds have excellent potential to be developed as a novel class of sensitizers of TRAIL.

Abstract
Earlier, a protein (BMP1, MW-79kDa) had been isolated from Indian toad (Bufo melanostictus) skin aqueous extract possessed anticancer activity against EAC bearing mice (Bhattacharjee et al., 2011). In the present study, the anti-proliferative and apoptogenic activities of BMP1 have been evaluated in leukemic (U937 and K562) and hepatoma (HepG2) cells. BMP1 dose dependently inhibited U937 and K562 cell growth having IC₅₀ values of 49 μg/ml and 30 μg/ml respectively. The anti-proliferative activity of BMP1 was observed in MTT assay, proliferating cell nuclear antigen (PCNA) expression and cell cycle arrest study. Flow-cytometric data revealed that BMP1 arrested cell cycle in U937 and K562 cells at Sub-G1 and G1 phases. The BMP1-induced dose dependent expressions of CDKIs (p21(cip1) and p27(kip1)) and inhibition of CDK2 and PCNA expression in HepG2 cells support the inhibition of cell proliferation due to G1 arrest. BMP1-induced apoptosis analyzed by annexin-V binding study and the DNA fragmentation by comet assay were correlated with the sub-G1 arrest. The parallel induction of bax and p53 expression in HepG2 cells and the up-regulation of caspase 3 and caspase 9 due to BMP1 treatment indicated the involvement of p53-dependent intrinsic pathway of apoptosis. BMP1 was found to be low immunogenic in nature.

Abstract
Cinobufacini (Huachansu) is a Chinese medicine prepared from the skin of Bufo bufo gargarizans Cantor (Bufonidae), which has long been used in traditional Chinese medicine (TCM). The aim of present study was to examine the anti-hepatitis B virus (HBV) activities of cinobufacini and its active components bufalin and cinobufagin in the human HBV-transfected cell line HepG2.2.15. The hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and hepatitis B core-related antigen (HBcrAg) concentrations in cell culture medium were determined by chemiluminescent enzyme immunoassay after HepG2.2.15 cells were respectively treated with different concentrations of cinobufacini, bufalin, and cinobufagin for 3 or 6 d. HBV DNA and mRNA were determined using transcription-mediated amplification and real-time polymerase chain reaction (PCR), respectively. On d 3, cinobufacini at a concentration of 1 µg/ml had no activity against HBV virological markers. However, on d 6, cinobufacini at 1 µg/ml effectively inhibited the secretion of HBsAg, HBeAg, and HBcrAg by 29.58, 32.87, and 42.52%. It was more potent than the positive control lamivudine (100 µg/ml). Bufalin and cinobufagin slightly inhibited HBV antigen secretion. Treatment with cinobufacini, bufalin, or cinobufagin had no anti-HBV effect on DNA in cell culture medium. Consistent with the HBV antigen reduction, HBV mRNA expression was markedly inhibited in comparison to the control when HepG2.2.15 cells were treated with cinobufacini, bufalin, or cinobufagin. Results suggested that cinobufacini had more potent activity against HBV antigen secretion than its components bufalin and cinobufagin and this inhibitory role was attributed to the specific inhibition of HBV mRNA expression.

Abstract
The skin of the toad Bufo bufo gargarizans Cantor is known to be rich in bufadienolides, peptides and alkaloids. It has been found to be a source of some extracts and biologically active compounds with antitumor activity. Cinobufacini (Huachansu), a Chinese medicine prepared from the dried toad skin, has been widely used in clinical therapy for various cancers in China. Bufadienolides, such as bufalin, cinobufagin, resibufogenin, and telocinobufagin, are the major active compounds derived from the toad skin. They are the maker biologically active compounds of cinobufagin while the antitumor activity of cinobufagin may be due to this kind of components. Experimental research has suggested that cinobufacini and its active compounds (e.g. bufalin and cinobufagin) exhibit significant antitumor activity, including inhibition of cell proliferation, induction of cell differentiation, induction of apoptosis, disruption of the cell cycle, inhibition of cancer angiogenesis, reversal of multi-drug resistance, and regulation of the immune response. Clinical data have indicated that cinobufacini may have effective anticancer activity with low toxicity and few side effects. Data to date suggest it may also enhance quality of life for patients with cancer. Thus, this review briefly summarizes recent studies on the anticancer activity of cinobufacini and some of its active compounds from the skin of the toad Bufo bufo gargarizans Cantor. This might provide additional evidence for further study of the extracts and active compounds from the toad skin in cancer treatment.

Abstract
Chan Su is a traditional Chinese medicine prepared from the dried white secretion of the auricular and skin glands of toads, and has been used as an oriental drug for the treatment of a number of diseases, including cancer. In this study, the potential of Chan Su (skin of Venenum Bufonis) to induce apoptosis in human lung carcinoma A549 cells was investigated. Treatment of A549 cells with skin of Venenum Bufonis resulted in the inhibition of cell growth and viability and the induction of apoptosis, which was shown by trypan blue counts, MTT assay, DAPI staining and flow cytometry analysis. The increase in apoptosis that was induced by skin of Venenum Bufonis was correlated with down-regulation of anti-apoptotic Bcl-2 expression, up-regulation of pro-apoptotic Fas ligand and death receptor 4, and a decrease in the mitochondrial membrane potential. Skin of Venenum Bufonis treatment induced the proteolytic activation of caspases and a concomitant degradation of poly(ADP-ribose)-polymerase and beta-catenin protein. Cleavage of Bid and a down-regulation of the inhibitor of apoptosis family proteins were also observed in skin of Venenum Bufonis-treated A549 cells. Data from this study indicates that SVB induces the apoptosis of A549 cells through a signaling cascade of death receptor-mediated extrinsic and mitochondria-mediated intrinsic caspase pathways.

Abstract
Adenosine can exhibit cytotoxic activity in vivo and in vitro, though its mechanisms are still uncertain. In this study, we investigated the adenosine-mediated apoptotic signaling pathway and the role of NF-kappaB in human hepatocellular carcinoma HepG2 cells. HepG2 cells were treated with different concentrations of adenosine for 12-48 h, and the effect of adenosine on cell proliferation was evaluated by MTT assay. The cytotoxicity of adenosine alone or in combination with an NF-kappaB inhibitor, pyrrolidine dithiocarbamate (PDTC), was also evaluated by MTT assay and the mode of cell death was detected by Hoechst 33342 staining. Cell cycle progress was performed by flow cytometry with PI staining. The protein expressions of Bcl-2, p53, NF-kappaB subunit p65, and caspase-3 were assayed by Western blot. Caspase-3 activity was measured by spectrophotomteric assay. The results showed that adenosine significantly reduced the viability of HepG2 cells in a dose- and time-dependent manner, with IC 50 (24 and 48 h) of 2.52 and 1.89 mmol x L(-1), respectively. The apoptotic index (percentage of sub-G1 phase) of HepG2 cells in adenosine treatment alone for 12 and 24 h or in combination with PDTC were 8.30%, 22.32% and 20.18%, 30.89%, respectively. All of them were higher than that in the control group (0.81%, p < 0.01). The characteristic changes of cell apoptosis (chromatin condensation and sub-G1 peak) were observed under fluorescent microscopy and flow cytometry. We also found that the apoptotic process triggered by adenosine was involved in G0-G1 cell-cycle arrest, enhanced the activity of caspase-3, upregulated p53 and NF-kappaB p65 expression, and downregulated Bcl-2 expression. Inhibition of NF-kappaB by PDTC decreased NF-kappaB p65 expression, enhanced cell apoptosis ratio, and increased caspase-3 activity. NF-kappaB may play an anti-apoptosis role in adenosine-induced HepG2 cytotoxicity.

Abstract
AIM: To analyze the clinical significance of survivin expression in hepatocellular carcinoma (HCC).
METHODS: The expression of survivin was examined by immunohistochemistry and semiquantitative RT-PCR in 76 HCC specimens. The correlation between survivin expression and clinicopathological parameters in HCC were analyzed. Survival data were analyzed using the Kaplan-Meier method and multivariate Cox proportional hazards model.
RESULTS: The positive rate of survivin protein expression in HCC was 69.74% (53/76). The relative expression level of survivin mRNA in HCC tissue was significantly higher than that in tumor-adjacent normal tissue (0.782 ± 0.284 vs 0.251 ± 0.064, P < 0.01). The positive expression of survivin was correlated with HbsAg positivity, Edmondson grade, portal vein tumor thrombus (PVTT) and tumor number in HCC, but not with cirrhosis, alpha-fetoprotein level, tumor size and pseudocapsule. The 1, 2, 3-year survival rates were 62.0%, 40.7% and 19.0% in survivin-positive group and 85.9%, 59.3% and 50.8% in survivin-negative group, respectively (P = 0.025). Multivariate Cox regression analysis showed that the positive expression of survivin, PTVV and tumor number were significant prognostic factors for HCC, and the risk ratios were 1.702, 1.994 and 6.391, respectively.
CONCLUSION: Overexpression of survivin may be involved in the development and progression of HCC. Detection of survivin expression will be helpful in selecting high-risk HCC patients. Survivin may be a promising target for HCC therapy.
