Abstract
Ethanol extracts of Cnidii Fructus, the dried fruits of Cnidium monnieri (L.) Cusson, have been externally applied in the treatment of Trichomonas vaginalis. However, the precise identity of the major constituents responsible for activity against T. vaginalis is unknown, but there is probability they are coumarin derivatives. In this study, the anti-Trichomonas activity of 4 major coumarin derivative constituents of Cnidii Fructus, namely, osthole, xanthotoxin, isopimpinellin, and bergapten, was characterized in terms of the resulting kinetics of growth and morphology of T. vaginalis upon treatment. The results demonstrated that osthole and xanthotoxol had significant trichomonacidal ability, while isopimpinellin and bergapten displayed low or no inhibitory efficacy toward T. vaginalis parasites. Our study suggests that the coumarin derivatives osthole and xanthotoxol can be potentially used as a basis for the development and design of new drugs for application in alternative or synergistic therapy against T. vaginalis.

Abstract
BACKGROUND/AIM Matrix metalloproteinase-2 (MMP-2) plays a critical role in the regulation of the extracellular matrix; however, its genotypes have seldom been examined in gastric cancer (GC). This study aimed to investigate the contribution of MMP-2 promoter -1306 (rs243865) and -735 (rs2285053) genotypes to GC risk in a cohort of Taiwanese individuals. MATERIALS AND METHODS This study included 121 GC cases and 363 age- and sex-matched controls. The genotypes of MMP-2 were determined by typical polymerase chain reaction-restriction fragment length polymorphism. RESULTS The genotypic and allelic frequency analysis showed that MMP-2 rs243865 variant genotypes decreased the risk of GC. Stratification analysis showed that MMP-2 rs243865 genotypes associate with smoking, alcohol drinking, and Helicobacter pylori infection status to confer personal susceptibility to GC. There is no such association for MMP-2 rs2285053 genotype with GC risk. CONCLUSION The MMP-2 rs243865 genotypes may serve as a novel predictive marker for GC personal susceptibility among Taiwanese.

Abstract
BACKGROUND/AIM Breast cancer incidence is highest among women worldwide, and practical markers for personalized therapeutic strategies are few. Interleukin-12 (IL-12) is a cytokine that is reported to be significantly lower in healthy controls than breast cancer cases, however, its genotypic contribution to carcinogenesis has never been revealed in breast cancer. We examined whether IL-12A rs568408 and rs2243115 genotypes contribute to elevated breast cancer risk and summarized related literature among other cancers. MATERIALS AND METHODS IL-12A genotypic profiles were determined among 1,232 breast cancer cases and 1,232 healthy controls via polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The variant genotypes of IL-12A rs568408 and rs2243115 were not found to be significantly associated with elevated breast cancer risk (both p>0.05). CONCLUSION IL-12A rs568408 and rs2243115 genotypes may not serve as good predictors of breast cancer risk.

Abstract
BACKGROUND/AIM Matrix metalloproteinase 9 (MMP9) is highly expressed in gastric cancer but the role of MMP9 is unclear. This study aimed at revealing the association of MMP9 promoter rs3918242 genotypes with gastric cancer risk. MATERIALS AND METHODS MMP9 rs3918242 genotypes of 121 patients with gastric cancer and 363 healthy individuals were examined by polymerase chain reaction-restriction fragment length polymorphism methodology using serum samples. RESULTS MMP9 rs3918242 TT genotype carriers had an elevated gastric cancer risk compared to wild-type CC carriers (odds ratio=3.92, 95% confidence interval=1.28-11.99; p=0.0103). Patients with CT/TT genotypes were at higher risk of metastasis (p=0.0178) than those with CC. No correlation was found between MMP9 rs3918242 genotype and gastric cancer risk with smoking or alcohol behavior, nor Helicobacter pylori infection. No correlation was observed for MMP9 rs3918242 genotypic distributions with age, gender, or body mass index. CONCLUSION Carrying a T allele for MMP9 rs3918242 may be predictive for higher gastric cancer risk, and as a predictor for higher risk of metastasis.

Abstract
BACKGROUND/AIM The molecular mechanisms underlying the association between cell cycle and asthma are poorly understood, and cyclin D1 (CCND1) is found to be upregulated in asthma airway smooth muscle. We investigated whether the most frequently examined functional variants in CCND1 determine asthma susceptibility. MATERIALS AND METHODS We genotyped 651 participants for single-nucleotide polymorphisms (SNPs) at rs9344 and rs678653 on CCND1 and assessed the association of these SNPs with asthma risk. RESULTS Significant differences were found in the distributions of genotypic (p=0.0064) and allelic (p=0.0021) frequencies of CCND1 rs9344. In addition, AG or GG carriers had 0.63- or 0.48-fold adjusted odds ratios for asthma risk (95%confidence intervals=0.48-0.92 and 0.22-0.78, respectively) than those who carried the AA wildtype. CONCLUSION Our results suggest that cell cycle regulation may play a role in asthma initiation and development, and the CCND1 rs9344 genotype may serve as an early detection marker for asthma.

Abstract
BACKGROUND/AIM Interleukin-16 (IL-16) is reported to play an important role in inflammation, carcinogenesis and tumoricidal processes, however, the contribution of IL-16 genotype to oral carcinogenesis is still largely unrevealed. Thus, the study aimed to investigate the contribution of IL-16 genotypes to Taiwan oral cancer risk. MATERIALS AND METHODS The genotypes of IL-16 rs4778889, rs11556218, and rs4072111 were revealed among 958 oral cancer cases and 958 control subjects by polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). RESULTS First, the distributions of genotypic (p=0.0004) and allelic (p=0.0001) frequencies of IL-16 rs11556218 were significantly different between the case and control groups. In detail, the frequencies of IL-16 rs11556218 TG and GG were 28.1 and 5.8%, respectively, among oral cancer patients, significantly higher compared to those among controls (25.0% and 2.7%, respectively). Second, no difference was observed regarding IL-16 rs4778889 or IL-16 rs4072111. Last, there was a synergistic effect of betel quid chewing behavior and risky IL-16 rs11556218 genotype on oral cancer risk. CONCLUSION The study indicates that the IL-16 rs11556218 G allele synergistically interacts with betel quid chewing behavior, contributing to increased risk of oral cancer in Taiwanese.

Abstract
BACKGROUND This study evaluated the impact of the adapted version of the Respecting Choices® The Living Matters Advance Care Planning (ACP) facilitator training programme on trainees' attitudes on facilitation 6 months post-training. SETTING AND PARTICIPANTS Two hundred and twenty-one healthcare professionals consisting of doctors, nurses, medical social workers from different training venues in Singapore participated in the first phase of the study (pre- and post) of which 107 participated in the second phase 6 months later (follow-up). METHODS Participants self-rated their attitudes, beliefs and behavioural intentions through surveys at three time points in an evaluation design that utilised repeated measures one-way ANOVA (pre-, post-, follow-up). Between-group differences were also examined using independent t-test. RESULTS At follow-up, mean scores increased significantly in understanding, confidence, and competence. Changes in effect sizes were large. Although trainees continued to think that ACP is emotionally draining for facilitators, more than before, facilitation experience was considered pleasant for themselves with the positive change significant and moderate in effect size. Those who had experience completing/initiating ACP significantly held more positive views than those who did not. CONCLUSIONS The ACP facilitator training programme had lasting effects on enhancing the understanding, competence, and confidence of trainees. Importantly, findings showed that experience in actual facilitation within 6 months after training was important and giving trainees opportunities to facilitate is recommended.

Abstract
BACKGROUND/AIM Xeroderma pigmentosum complementation group C (XPC) is reported to play important roles in DNA integrity and genomic instability, however, the contribution of XPC to oral carcinogenesis is largely uncertain. Therefore, we aimed at examining the contribution of XPC genotypes to oral cancer. MATERIALS AND METHODS The genotypes of XPC rs2228001 and rs2228000 were examined among 958 oral cancer patients and 958 control subjects by polymerase chain reaction-restriction fragment length polymorphism methodology and corresponding DNA repair capacity was checked. RESULTS First, the percentages of XPC rs2228001 AC and CC were higher among oral cancer patients than controls. Second, no significant association was observed regarding XPC rs2228000. Third, there was a synergistic influence of smoking and betel quid chewing behaviors and XPC rs2228001 genotype on oral cancer risk. Last, functional experiments showed DNA repair capacity was lower for AC/CC carriers than AA carriers. CONCLUSION XPC rs2228001 C allele, which was associated with decreased DNA repair capacity, may interact with smoking and betel quid chewing behaviors on oral cancer risk.

Abstract
BACKGROUND/AIM Matrix metalloproteinase-1 is responsible for extracellular matrix regulation, and its genetic role in colorectal cancer (CRC) is unclear. The aim of the study was to investigate the contribution of Matrix metalloproteinase-1 genotypes to CRC risk in Taiwan. MATERIALS AND METHODS A total of 362 cases and 362 controls were included and their MMP-1 -1607 (rs1799705) genotypes were examined. The environmental factors and clinical-pathological records were also analyzed. RESULTS The genotypic frequency of MMP-1 rs1799750 were different between the CRC and control groups (p for trend=0.0083). 1G/2G and 1G/1G were associated with lower risk (p=0.0438 and 0.0030, adjusted OR=0.73 and 0.54, 95%CI=0.54-0.90 and 0.37-0.83). Among non-smokers, those with 1G/2G and 1G/1G genotypes were at 0.70- and 0.48-fold odds of having CRC. Among non-alcohol drinkers, people with 1G/2G and 1G/1G genotypes were at 0.71- and 0.54-fold odds. The 1G/1G genotype were statistically lower among CRC patients with lymph node metastasis (7.2%) than those without (19.0%). CONCLUSION The genotypes at MMP-1 rs1799705 play a role in determining susceptibility to CRC risk in Taiwan.

Abstract
Oxidative stress may play critically important roles in the etiology of Parkinson's disease (PD). 6-Hydroxydopamine (6-OHDA) is a physiological neurotoxin reported to induce oxidative-induced apoptosis of dopaminergic neurons in PD mice models. Valproic acid (VPA), a clinical mood stabilizer, is a HDAC inhibitor with neuroprotective capacities. In the study, we aim at examining the feasibility of VPA as a protector for dopaminergic neurons against damage from 6-OHDA, and the intracellular mechanisms. The 6-OHDA-induced neurotoxicity to the human dopaminergic cell line SH-SY5Y was applied for examining VPA protective effects. Pretreatment with VPA was able to improve cell viability and reduce 6-OHDA-induced reactive oxygen species. Furthermore, a significant suppression of apoptotic caspases including cleaved caspase-3, caspase-7, and caspase-9 was observed. The results also revealed VPA decreased the 6-OHDA-induced Bax/Bcl2 ratio, as measured at protein level. These novel findings indicate that VPA may be capable of protecting the SH-SY5Y dopaminergic neuronal cells from 6-OHDA-induced toxicity via the deceasing of apoptotic caspases (cleaved caspase-3, caspase-7, and caspase-9) and reducing of the Bax/Bcl2 ratio. Very possibly, VPA could serve as not only a mood stabilizer but also a potential antidote for PD prevention.

Abstract
BACKGROUND/AIM In literature, few studies have examined the diagnostic or prognostic potential of matrix metalloproteinases (MMP) in pterygium, whose formation and progression are closely related to imbalance in the extracellular microenvironment. In this study, we investigated the contribution of MMP7 promoter (A-181G and C-153T) polymorphic genotypes to pterygium risk. MATERIALS AND METHODS A total of 134 cases and 268 controls were collected and their MMP7 genotypes at A-181G and C-153T were examined by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The AA, AG and GG genotypes at MMP7 promoter A-181G were non-significantly differentially distributed between the two groups at 85.8, 11.2 and 3.0%, respectively, in pterygium cases and 88.4, 9.7 and 1.9% in controls, respectively (p for trend=0.6822). There was no polymorphic genotype for MMP7 C-153T among our Taiwanese cohort. CONCLUSION A-181G and C-153T genotypes at MMP7 do not have a direct role in determining Taiwanese susceptibility to pterygium.

MATERIALS AND METHODS A total of 1232 breast cancer patients and 1232 age-matched controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology. RESULTS Genotypic frequencies of IL-4 rs2243248, rs2243250 and rs2070874 were not differentially distributed between case and control groups. Consistently, there was no difference in the distribution of allelic frequencies among patients and controls. CONCLUSION IL-4 rs2243248, rs2243250 and rs2070874 do not confer breast cancer susceptibility in Taiwanese.

Abstract
AIM To investigate the association between adiponectin (ADIPOQ) genotypes and colorectal cancer (CRC) risk among Taiwanese. MATERIALS AND METHODS Polymerase chain reaction-restriction fragment length polymorphism was adopted to identify ADIPOQ rs266729, rs2241766 and rs1501299 genotypes among 362 CRC patients and 362 healthy controls. RESULTS ADIPOQ rs266729 GG genotype (p=0.0075) and G allele (p=0.0061) are associated with a significantly increased CRC risk. There is no differential distribution of rs2241766 and rs1501299 genotypes. As for the gene-lifestyle interaction, there are obvious joint effects of rs266729 genotype on the CRC risk among non-smoker, non-alcohol drinker, while not on smoker or non-drinker subgroups. No significant correlation was observed between rs266729 genotypic distributions and age, gender, tumor size, location or metastasis status. Interestingly, a correlation of rs266729 genotype and larger BMI on CRC risk was found. CONCLUSION G allele at ADIPOQ rs266729 may serve as a determiner for CRC risk, especially for those with BMI ≥24.

Abstract
BACKGROUND/AIM Few studies have examined the contribution of matrix metalloproteinases (MMP) to either diagnosis or prognosis of pterygium. The aim of this study was to investigate the contribution of MMP-1 genotypes to pterygium risk. PATIENTS AND METHODS A total of 134 cases and 268 controls were included and their MMP-1 -1607 (rs1799705) genotypes were examined by polymerase chain reaction-restriction fragment length polymorphism. RESULTS The percentages of 2G/2G, 1G/2G, and 1G/1G for rs1799705 genotypes were 48.5, 36.6 and 14.9% among patients and 33.9, 44.8, and 21.3% among controls (p trend=0.0167). The odds ratios (ORs) after adjusting for age and gender for 1G/2G and 1G/1G genotypes at rs1799705 were 0.54 (95%CI=0.33-0.89, p=0.0168) and 0.46 (95%CI=0.27-0.88, p=0.0192), respectively. Consistently, the adjusted OR for those carrying the 1G allele at MMP-1 -1607 was 0.61 (95%CI=0.41-0.78, p=0.0167), compared with the wild-type 2G allele. CONCLUSION The genotypes at rs1799705 play a role in determining personal susceptibility to pterygium.

Abstract
BACKGROUND/AIM Few studies have examined the genetic role of matrix metalloproteinases (MMPs) to early detection or prediction in gastric cancer development. In this study, the contribution of MMP7 promoter (A-181G and C-153T) polymorphic genotypes to gastric cancer risk in Taiwanese was investigated for the first time. MATERIALS AND METHODS A total of 121 cases and 363 controls were enrolled and their MMP7 genotypes at A-181G and C-153T were examined by polymerase chain reaction-restriction fragment length polymorphism methodology using genomic DNA from serum. RESULTS The GG genotype at MMP7 A-181G was found to represent a risk factor for gastric cancer, especially among smokers. No individual with variant genotype carrier at MMP7 C-153T was found among this Taiwanese population. CONCLUSION The G allele of MMP7 A-181G may serve as an early predictor for gastric cancer risk in Taiwanese; other gastric cancer markers are still urgently needed.

Abstract
Abstract
Background
Brugada syndrome (BrS) is a sudden arrhythmic death. The prevalence of BrS is higher in the Southeast Asian populations than that in Caucasian patients. A previous genome-wide association study (GWAS) has reported 13 SNPs significantly associated with BrS. However, no study was performed to validate whether these SNPs are enriched in BrS patients in Han Chinese (HC).
Purpose
Evaluating the common variants previously reported in Caucasian BrS patients could be generalized to HC BrS patients in Taiwan
Methods
We genotyped 200 unrelated BrS patients using Affymetrix TWB Array (N=653,291 SNPs, a customized array for HC in Taiwan). The controls are obtained from the Taiwan Biobank (N ≈ 16,000) using the same array. An imputation workflow was shown in Figure 1. To confirm the accuracy of the imputed genotype of each variant, Sanger sequencing was performed in 10% of randomly selected cases.
Results
Among the 3 most important common variants (rs11708996 in SCN5A, rs10428132 in SCN10A and rs9388451 in HEY2/NCOA7) reported in the previous GWAS mainly conducted in Caucasian BrS patients, 2 of them (rs10428132 and rs9388451) were successfully replicated in the HC population in Taiwan (P<0.01). We also found that the differences of minor allele frequency (dMAF: the MAF of cases minus the MAF of controls) of the two variants were relatively smaller between the BrS cases and healthy controls in HC population compared with that in Caucasian populations (dMAF, rs9388451: 0.15 (Caucasian) vs −0.07 (HC); rs10428132: 0.28 (Caucasian) vs 0.11 (HC)). For the remaining 10 common variants reaching genome-wide significance (P=5×10–8) in Caucasian BrS patients, 9 of them were also significantly enriched in the HC BrS patients after the Bonferroni correction (P<0.05/12=0.0042). We next analyzed the variants identified in the previous GWAS on ECG traits (PR interval, QRS duration, QTc interval, and heart rate) in the Caucasian population. Among the reported 75 variants associated with ECG traits, 5 common variants (rs6798015 (PR), rs1760876 (QRS), rs6795970 (PR/QRS), rs2074238 (QTc) and rs314370 (heart rate)) were significant after Bonferroni correction (P<0.05/75=0.00066).
Figure 1
Conclusions
The preliminary results indicated that 85% of common variants of SCN10A and HEY2/NCOA7 previously reported in Caucasian BrS patients are replicated in BrS patients in the HC population but not the common variant of SCN5A (rs11708996). Furthermore, the common variants of SCN10A and HEY2/NCOA7 related to cardiac depolarization or repolarization may also contribute to the development of BrS.

Abstract
Interleukin-18 (IL-18) is a multi-functional immuno-mediator in the development and progression of many types of infectious and inflammatory diseases. In this study, we evaluated the contribution of IL-18 genotypes to renal cell carcinoma (RCC) in Taiwan via the genotyping of IL-18 -656 (A/C), -607 (A/C), and -137 (G/C). Moreover, we analyzed their interactions with smoking, alcohol drinking, hypertension, and diabetes status. The results showed an association of the AC and CC genotypes of IL-18 -607 with a significant decrease in the risk of RCC compared with the AA genotype (odds ratio (OR) = 0.44 and 0.35, 95% confidence interval (CI) = 0.27⁻0.72 and 0.18⁻0.66, p = 0.0008 and 0.0010, respectively). Furthermore, a significantly lower frequency of the C allele at -607 was observed in the RCC group (35.3% vs. 49.8%; OR = 0.53; 95% CI = 0.35⁻0.71, p = 0.0003). However, IL-18 -656 and -137 did not exhibit a likewise differential distribution of these genotypes between the control and case groups. Stratifying the population according to smoking, alcohol drinking, hypertension, and diabetes status revealed a different distribution of IL-18 -607 genotypes among non-smokers, non-drinkers, and patients without diabetes, but not among smokers, drinkers, or patients with diabetes. These findings suggest that IL-18 -607 genotypes may play a role in the etiology and progression of RCC in Taiwan and may serve as a useful biomarker for early detection.

Abstract
Cantharidin (CTD), a component of natural mylabris (Mylabris phalerata Pallas), has been shown to have biological activities and induce cell death in many human cancer cells. In the present study, we investigated the effect of CTD on cell migration and invasion of NCI-H460 human lung cancer cells. Cell viability was examined and results indicated that CTD decreased the percentage of viable cells in dose-dependent manners. CTD inhibited cell migration and invasion in dose-dependent manners. Gelatin zymography analysis was used to measure the activities of matrix metalloproteinases (MMP-2/-9) and the results indicated that CTD inhibited the enzymatic activities of MMP-2/-9 of NCI-H460 cells. Western blotting was used to examine the protein expression of NCI-H460 cells after incubation with CTD and the results showed that CTD decreased the expression of MMP-2/-9, focal adhesion kinase (FAK), Ras homolog gene family, member A (Rho A), phospho-protein kinase B (AKT) (Thr308)(p-AKT(308)), phospho-extracellular signal-regulated kinase1/2 (p-ERK1/2), phospho-p38 mitogen-activated protein (MAP) kinase (p-p38), phospho c-Jun N-terminal kinase 1/2 (p-JNK1/2), nuclear factor-κB (NF-κB) and urokinase plasminogen activator (UPA). Furthermore, confocal laser microscopy was used to confirm that CTD suppressed the expression of NF-κB p65, but did not significantly affect protein kinase C (PKC) translocation in NCI-H460 cells. Based on those observations, we suggest that CTD may be used as a novel anticancer metastasis agent for lung cancer in the future.

Abstract
Isothiocyanates (ITCs) occur in many cruciferous vegetables. These compounds, which have significant anticancer actions, can induce apoptosis in different human cancer cell lines. In the present study, we investigated if allyl isothiocyanate (AITC) would induce toxicity in human breast cancer MCF-7 (estrogen receptor positive) and MDA-MB-231 (estrogen receptor negative) cells. We found that AITC stimulated reactive oxygen species and Ca[Formula: see text] production, and decreased the mitochondrial membrane potential. Activity of caspase-8, -9 and -3 was increased by AITC in both cell lines. AITC also induced mitochondrial-mediated apoptosis, as shown by cytochrome c, AIF and Endo G release from mitochondria, activation of caspase-9 and caspase-3, and formation of DAPI-positive cells. There was a significant reduction in the levels of the anti-apoptotic protein Bcl-2 along with a marked increase in the pro-apoptotic protein Bax in both cell lines. AITC induced apoptosis in human breast cancer MCF-7 cells via AIF and Endo G signaling pathways, but in MDA-MB-231 cells apoptosis occurred via the GADD153 pathway. This study has revealed novel anti-cancer mechanisms of AITC, a compound that is ordinarily present in human diets and may have potential therapeutic effects in various cancers.

Abstract
Nonsmall cell lung carcinoma (NSCLC) is a devastating primary lung tumor resistant to conventional therapies. Bisdemethoxycurcumin (BDMC) is one of curcumin derivate from Turmeric and has been shown to induce NSCLC cell death. Although there is one report to show BDMC induced DNA double strand breaks, however, no available information to show BDMC induced DNA damage action with inhibited DNA repair protein in lung cancer cells in detail. In this study, we tested BDMC-induced DNA damage and condensation in NCI-H460 cells by using Comet assay and DAPI staining examinations, respectively and we found BDMC induced DNA damage and condension. Western blotting was used to examine the effects of BDMC on protein expression associated with DNA damage and repair and results indicated that BDMC suppressed the protein levels associated with DNA damage and repair, such as 14-3-3σ (an important checkpoint keeper of DDR), O6-methylguanine-DNA methyltransferase, DNA repair proteins breast cancer 1, early onset, mediator of DNA damage checkpoint 1 but activate phosphorylated p53 and p-H2A.X (phospho Ser140) in NCI-H460 cells. Confocal laser systems microscopy was used for examining the protein translocation and results show that BDMC increased the translocation of p-p53 and p-H2A.X (phospho Ser140) from cytosol to nuclei in NCI-H460 cells. In conclusion, BDMC induced DNA damage and condension and affect DNA repair proteins in NCI-H460 cells in vitro. © 2015 Wiley Periodicals, Inc. Environ Toxicol 31: 1859-1868, 2016.

Abstract
Cancer is the second cause of death in children. Osteosarcoma is the most common primary malignancy of solid bone cancer primarily affecting adolescents and young adults. In the Chinese population, the crude extract of Rheum palmatum L. (CERP) has been used for treating different diseases, including SARS, rheumatoid arthritis, coxsackievirus B3, and human colon cancer cell, pancreatic cancer. There are no reports on CERP and human osteosarcoma cells. The present study examined effects of CERP on cytotoxicity including cell cycle distribution and cell death (apoptosis) in U-2 OS human osteosarcoma cells. CERP significantly induced S phase arrest in U-2 OS cells in a dose-dependent. CERP produced DNA damage and DNA condensation. Other effects of CERP were stimulation of ROS and Ca(2+) , mitochondria impairment, and activation of caspase-3, -8, and -9. CERP increased the levels of Bax, Bak, Bad, cyclin B, Fas, PARP, GRP78, GADD153, AIF, Endo G, Calpain-2, p21, and p27, but decreased the levels of Bcl-2, BCL-X, XIAP, Akt, CDC25A, CDK2, Cyclin A, and Cyclin E of U-2 OS cells. It was also observed that CERP promoted the expression of AIF, Endo G, GADD153, and cytochrome c. These results indicate that CERP has anticancer effects in vitro and provide the foundation for in vivo studies of animal models of osteosarcoma. © 2015 Wiley Periodicals, Inc.

Abstract
Casticin, a polymethoxyflavone occurring in natural plants, has been shown to have anticancer activities. In the present study, we aims to investigate the anti-skin cancer activity of casticin on melanoma cells in vitro and the antitumor effect of casticin on human melanoma xenografts in nu/nu mice in vivo. A flow cytometric assay was performed to detect expression of viable cells, cell cycles, reactive oxygen species production, levels of [Formula: see text] and caspase activity. A Western blotting assay and confocal laser microscope examination were performed to detect expression of protein levels. In the in vitro studies, we found that casticin induced morphological cell changes and DNA condensation and damage, decreased the total viable cells, and induced G2/M phase arrest. Casticin promoted reactive oxygen species (ROS) production, decreased the level of [Formula: see text], and promoted caspase-3 activities in A375.S2 cells. The induced G2/M phase arrest indicated by the Western blotting assay showed that casticin promoted the expression of p53, p21 and CHK-1 proteins and inhibited the protein levels of Cdc25c, CDK-1, Cyclin A and B. The casticin-induced apoptosis indicated that casticin promoted pro-apoptotic proteins but inhibited anti-apoptotic proteins. These findings also were confirmed by the fact that casticin promoted the release of AIF and Endo G from mitochondria to cytosol. An electrophoretic mobility shift assay (EMSA) assay showed that casticin inhibited the NF-[Formula: see text]B binding DNA and that these effects were time-dependent. In the in vivo studies, results from immuno-deficient nu/nu mice bearing the A375.S2 tumor xenograft indicated that casticin significantly suppressed tumor growth based on tumor size and weight decreases. Early G2/M arrest and mitochondria-dependent signaling contributed to the apoptotic A375.S2 cell demise induced by casticin. In in vivo experiments, A375.S2 also efficaciously suppressed tumor volume in a xenotransplantation model. Therefore, casticin might be a potential therapeutic agent for the treatment of skin cancer in the future.

Abstract
Diallyl trisulfide (DATS), a chemopreventive dietary constituent and extracted from garlic, has been shown to against cultured many types of human cancer cell liens but the fate of apoptosis in murine leukemia cells in vitro and immune responses in leukemic mice remain elusive. Herein, we clarified the actions of DATS on growth inhibition of murine leukemia WEHI-3 cells in vitro and used WEHI-3 cells to generate leukemic mice in vivo, following to investigate the effects of DATS in animal model. In in vitro study, DATS induced apoptosis of WEHI-3 cells through the G0/G1 phase arrest and induction of caspase-3 activation. In in vivo study DATS decreased the weight of spleen of leukemia mice but did not affect the spleen weight of normal mice. DATS promoted the immune responses such as promotions of the macrophage phagocytosis and NK cell activities in WEHI-3 leukemic and normal mice. However, DATS only promotes NK cell activities in normal mice. DATS increases the surface markers of CD11b and Mac-3 in leukemia mice but only promoted CD3 in normal mice. In conclusion, the present study indicates that DATS induces cell death through induction of apoptosis in mice leukemia WHEI-3 cells. DATS also promotes immune responses in leukemia and normal mice in vivo.

Abstract
BACKGROUND/AIM Lung cancer is one of the most common malignancies and a predominant cause of cancer-related death. It can metastasize in almost all organs, and currently, while new cases are increasing, treatment is still insufficient. Bisdemethoxycurcumin (BDMC), one of the components of turmeric, has been known to possess biological activities. However, the effects of BDMC on the genetic level remain unclear. MATERIALS AND METHODS Human lung cancer NCI-H460 cells were treated with 35 μM BDMC for 24 h and cells were harvested for total RNA extraction. The purified RNA was used for cDNA synthesis, labeling, microarray hybridization, and flour-labeled cDNA on-chip hybridization. The expression Console software (Affymetrix) with default RNA parameters was used to detect and quantitate concentrations of fluorescent molecules. The key genes involved and their possible interaction pathways were analyzed by the GeneGo software. RESULTS Seven genes, such as CCNE2 (cyclin E), associated with cell cycle, were over 4-fold overexpressed, 22 genes, such as ERCC6L (excision repair cross-complementing rodent repair deficiency, complementation group 6-like) associated with DNA damage and repair, were from 3- to 4-fold overexpressed and 266, such as cell division cycle, S-phase associated kinase and associated with cell death, genes were from 2- to 3-fold overexpressed. CONCLUSION BDMC induced changes in gene expression that may reveal cytotoxic information on the genetic level while presenting novel biomarkers or targets for treatment of human lung cancer in the future.

Abstract
Solanum lyratum (SLEC) Thunberg (Solanaceae) has been used as a traditional herbal medicine in China for centuries. Numerous studies have shown that SLEC Thunberg (Solanaceae) extract inhibited cancer cell growth in vitro. Herein, we investigated cell death-induced by EcoAc, water, chloroform, butanol extract of SLEC in human oral cancer cell lines (HSC-3, SAS, and CAL-27) in vitro. Different SLEC extract induced cytotoxic effects in human oral cancer cells were examined by contrast phase microscopy. We selected the chloroform extract of SLEC to examine the cytotoxic effects by using DAPI staining, comet assays, flow cytometric assay, Western blotting and examination of confocal laser microscopy. SLEC decreased the percentage of viable cells, induced G0/G1 arrest and apoptosis. These effects were concentration- and time-dependent manners. SLEC increased protein levels of p21, p16, CDK2, and cyclin D1 in HSC-3, SAS, and CAL-27 cells. Also, SLEC increased CDK6 in HSC-3 and CAL-27 cells, but inhibited CDK6 in SAS cells. Cyclin E in HSC-3 and SAS cells was increased by SLEC, but it was inhibited in CAL-27 cells. SLEC suppressed the anti-apoptotic proteins Bcl-2 and Bcl-xl, but increased the pro-apoptotic proteins Bax and Bad in HSC-3, SAS, and CAL-27 cells. SLEC promoted the production of reactive oxygen species (ROS) and Ca²⁺, decreased the mitochondrial membrane potential (Δψm) and stimulated NO production in HSC-3, SAS, and CAL-27 cells. Specific caspase inhibitors (caspase-8 inhibitor: Z-IETD-FMK; caspase-9 inhibitor: Z-LEHD-FMK and caspase-3 inhibitor: Z-DEVD-FMK) for caspase-8, -9, and -3 blocked SLE-activated caspase-8, -9, and -3 activities which were associated with an increase in the percentage of viable cells. Taken together, SLE induced G0/G1 arrest and apoptosis via extrinsic- and intrinsic-dependent pathways in HSC-3, SAS, and CAL-27 cells.

Abstract
The study goal was to evaluate the effects of curcumin on DNA damage and expression of DNA-repair proteins in human lung cancer. Thus, NCI-H460 cells were used to study the effects of curcumin on DNA damage and repair in vitro. We investigated curcumin induces DNA damage by comet the assay and 4',6-diamidino-2-phenylindole (DAPI) staining. The DNA damage/repair-related protein levels were examined and monitored by western blotting and confocal microscopy. Curcumin significantly increased the length of comet tails and DNA condensation in NCI-H460 cells. Curcumin reduced expression of DNA-repair proteins such as 14-3-3 protein sigma (14-3-3σ), O6-methylguanine-DNA methyltransferase (MGMT), breast cancer susceptibility gene 1 (BRCA1), and mediator of DNA damage checkpoint 1 (MDC1). Curcumin also increased phosphorylation of p53 and Histone H2A.X (S140) in the nuclei of NCI-H460 cells. Taken together, our findings indicated that curcumin triggered DNA damage and inhibited expression of DNA-repair-associated proteins in NCI-H460 cells.

Abstract
AIM A decrease of systolic blood pressure in excess of 20 mmHg during haemodialysis treatment (IDD) is common for haemodialysis patients. Intradialytic hypotension (IDH) is symptomatic IDD by definition. Overproduction of nitric oxide (NO) is a possible cause of IDD. Dialysate nitrate and nitrite amount can be used as an indicator of intradialysis NO production. Our aim was to find the predictor of NO production in IDD patients. METHODS Partial dialysate samples were collected during the whole haemodialysis session and total dialysate nitrate and nitrite amount was measured to assess the association of intradialysis NO production with blood pressure change. RESULTS There were 31 IDD patients and 71 patients who did not develop IDD (NIDD) included in the study. Among the IDD patients, 13 were IDH patients with a mean systolic blood pressure lower than that of the other 18 symptomless IDD patients (96.6 ± 3.4 mmHg vs 125.0 ± 3.8 mmHg, P<0.001). The median value of NO production was higher in the IDD than in the NIDD patients (447.7 μg vs 238.8 μg, P<0.001). The NO production correlated linearly with blood pressure reduction (R=0.487, P<0.001). The multivariate analysis showed that NO production was positively associated with predialysis systolic blood pressure. CONCLUSION Nitric oxide production during haemodialysis was higher in IDD than in NIDD patients. IDH often occurred when systolic blood pressure was reduced to below 100 mmHg. The amount of NO produced during haemodialysis, which may be associated with predialysis systolic blood pressure, can be used to predict intradialysis blood pressure decrease.

Abstract
Cantharidin (CTD) induces cytotoxic effects in different types of human cancer cell; however, to date, there have been no studies on the effects of CTD on gene expression in human lung cancer cells and the potential associated signaling pathways. Therefore, the present study aimed to investigate how CTD affects the expression of key genes and functional pathways of human H460 lung cancer cells using complementary DNA microarray analysis. Human H460 lung cancer cells were cultured for 24 h in the presence or absence of 10 µM CTD; gene expression was then examined using microarray analysis. The results indicated that 8 genes were upregulated > 4-fold, 29 genes were upregulated >3-4-fold and 156 genes were upregulated >2-3-fold. In addition, 1 gene was downregulated >4 fold, 14 genes were downregulated >3-4-fold and 150 genes were downregulated >2-3 fold in H460 cells following exposure to CTD. It was found that CTD affected DNA damage genes, including DNIT3 and GADD45A, which were upregulated 2.26- and 2.60-fold, respectively, as well as DdiT4, which was downregulated 3.14-fold. In addition, the expression of genes associated with the cell cycle progression were altered, including CCND2, CDKL3 and RASA4, which were upregulated 2.72-, 2.19- and 2.72-fold, respectively; however, CDC42EP3 was downregulated 2.16-fold. Furthermore, apoptosis-associated genes were differentially expressed, including CARD6, which was upregulated 3.54-fold. In conclusion, the present study demonstrated that CTD affected the expression of genes associated with DNA damage, cell cycle progression and apoptotic cell death in human lung cancer H460 cells.

Abstract
Osteosarcoma is the most common primary malignancy of the bone cancers. In the Chinese population, the crude extract of Corni Fructus (CECF) has been used as Traditional Chinese medicine to treat several different diseases for hundreds of years. In the present study, effects of CECF on inhibition of migration and invasion in U-2 OS human osteosarcoma cells were examined. CECF significantly inhibited migration and invasion of U-2 OS human osteosarcoma cells. We also found that CECF inhibited activities of matrix metalloproteinases-2 (MMP-2) and matrix metalloproteinases-9 (MMP-9). CECF decreased protein levels of FAK, PKC, SOS1, MKK7, MEKK3, GRB2, NF-κB p65, COX-2, HIF-1α, PI3K, Rho A, ROCK-1, IRE-1α, p-JNK1/2, p-ERK1/2, p-p38, Ras, p-PERK, MMP-2, MMP-9, and VEGF in U-2 OS cells. Results of this study indicate that CECF may have potential as a novel anticancer agent for the treatment of osteosarcoma by inhibiting migration and invasion of cancer cells.

Abstract
Angiogenesis inhibitors are beneficial for the prevention and treatment of angiogenesis-dependent diseases including cancer. We examined the cytotoxic, anti-metastatic, anti-cancer and anti-angiogenic effects of diallyl trisulfide (DATS). In HT29 cells, DATS inhibited migration and invasion through the inhibition of focal adhesion kinase (FAK), extracellular signal-regulated kinase, c-Jun N-terminal kinase and p38 which was associated with inhibition of matrix metalloproteinases-2, -7 and -9 and VEGF. In human umbilical vein endothelial cells (HUVEC), DATS inhibited the migration and angiogenesis through FAK, Src and Ras. DATS also inhibited the secretion of VEGF. The capillary-like tube structure formation and migration by HUVEC was inhibited by DATS. The chicken egg chorioallantoic membrane (CAM) assay indicated that DATS treatment inhibited ex-vivo angiogenesis. We investigated the anti-tumour effects of DATS against human colon cancer xenografts in BALB/cnu/nu mice and its anti-angiogenic activity in vivo. In this in-vivo study, DATS also inhibited the tumour growth, tumour weight and angiogenesis (decreased the levels of haemoglobin) in HT29 cells. In conclusion, the present results suggest that the inhibition of angiogenesis may be an important mechanism in colon cancer chemotherapy by DATS.

Abstract
Crude extract of Rheum palmatum L (CERP) has been used to treat different diseases in the Chinese population for decades. In this study, we investigated the effects of CERP on LS1034 human colorectal cancer cells in vitro and also examined possible mechanisms of cell death. Flow cytometric assays were used to measure the percentage of viable cells, cell cycle distribution including the sub-G1 phase (apoptosis), the activities of caspase-8, -9, and -3, reactive oxygen species (ROS) and Ca(2+) levels, and mitochondrial membrane potential (ΔΨm). DNA damage, nuclei condensation, protein expression, and translocation were examined by Comet assay, 4'-6-diamidino-2-phenylindole (DAPI) staining, Western blotting, and confocal laser system microscope, respectively. CERP induced apoptosis as seen by DNA fragmentation and DAPI staining in a concentration- and time-dependent manner in cancer cells. CERP was associated with an increase in the Bax/Bcl-2 protein ratio and CERP promoted the activities of caspase-8, -9, and -3. Both ROS and Ca(2+) levels were increased by CERP but the compound decreased levels of ΔΨm in LS1034 cells. Laser confocal microscope also confirmed that CERP promoted the expressions of AIF, Endo G, cytochrome c, and GADD153 to induce apoptosis through mitochondrial-dependent pathway.

Abstract
Crude extract of Corni Fructus (CECF) has been used in Traditional Chinese medicine for the treatment of different diseases for hundreds of years. The purpose of this study was to investigate the cytotoxic effects of CECF on U-2 OS human osteosarcoma cells. Flow cytometry was used for measuring the percentage of viable cells, cell-cycle distribution, apoptotic cells in sub-G1 phase, reactive oxygen species (ROS), Ca(2+) levels, and mitochondrial membrane potential (ΔΨm ). Comet assay and 4'-6-diamidino-2-phenylindole staining were used for examining DNA damage and condensation. Western blotting was used to examine apoptosis-associated protein levels in U-2 OS cells after exposed to CECF. Immunostaining and confocal laser system microscope were used to examine protein translocation after CECF incubation. CECF decreased the percentage of viability, induced DNA damage and DNA condensation, G₀/G₁ arrest, and apoptosis in U-2 OS cells. CECF-stimulated activities of caspase-8, caspase-9, and caspase-3, ROS, and Ca(2+) production, decreased ΔΨm levels of in U-2 OS cells. CECF increased protein levels of caspase-3, caspase-9, Bax, cytochrome c, GRP78, AIF, ATF-6α, Fas, TRAIL, p21, p27, and p16 which were associated with cell-cycle arrest and apoptosis. These findings suggest that CECF triggers apoptosis in U-2 OS cells via ROS-modulated caspase-dependent and -independent pathways.

Abstract
α-phellandrene (α-PA) is a cyclic monoterpene, present in natural plants such as Schinus molle L. α-PA promotes immune responses in mice in vivo. However, there is no available information on whether α-PA affects gene expression in leukemia cells. The present study determined effects of α-PA on expression levels of genes associated with DNA damage, cell cycle and apoptotic cell death in mouse leukemia WEHI-3 cells. WEHI-3 cells were treated with 10 μM α-PA for 24 h, cells were harvested and total RNA was extracted, and gene expression was analyzed by cDNA microarray. Results indicated that α-PA up-regulated 10 genes 4-fold, 13 by over 3-fold and 175 by over 2-fold; 21 genes were down-regulated by over 4-fold, 26 genes by over 3-fold and expression of 204 genes was altered by at leas 2-fold compared with the untreated control cells. DNA damage-associated genes such as DNA damage-inducer transcript 4 and DNA fragmentation factor were up-regulated by 4-fold and over 2-fold, respectively; cell-cycle check point genes such as cyclin G2 and cyclin-dependent kinases inhibitor 2D and IA (p21) were up-regulated by over 3-fold and over 2-fold, respectively; apoptosis-associated genes such as BCL2/adenovirus EIB interacting protein 3, XIAP-associated factor 1, BCL2 modifying factor, caspase-8 and FADD-like apoptosis regulator were over 2-fold up-regulated. Furthermore, DNA damage-associated gene TATA box binding protein was over 4-fold down-regulated, and D19Ertd652c (DNA segment) over 2-fold down-regulated; cell cycle-associated gene cyclin E2 was over 2-fold down-regulated; apoptosis associated gene growth arrest-specific 5 was over 9-fold down-regulated, Gm5426 (ATP synthase) was over 3-fold down-regulated, and death box polypeptide 33 was over 2-fold down-regulated. Based on these observations, α-PA altered gene expression in WEHI-3 cells in vitro.

Abstract
Lung cancer is one of the leading causes of death in cancer-related diseases. Cantharidin (CTD) is one of the components of natural mylabris (Mylabris phalerata Pallas). Numerous studies have shown that CTD induced cytotoxic effects on cancer cells. However, there is no report to demonstrate that CTD induced apoptosis in human lung cancer cells. Herein, we investigated the effect of CTD on the cell death via the induction of apoptosis in H460 human lung cancer cells. Flow cytometry assay was used for examining the percentage of cell viability, sub-G1 phase of the cell cycle, reactive oxygen species (ROS) and Ca²⁺ productions and the levels of mitochondrial membrane potential (∆Ψm). Annexin V/PI staining and DNA gel electrophoresis were also used for examining cell apoptosis. Western blot analysis was used to examine the changes of apoptosis associated protein expression and confocal microscopy for examining the translocation apoptosis associated protein. Results indicated that CTD significantly induced cell morphological changes and decreased the percentage of viable H460 cells. CTD induced apoptosis based on the occurrence of sub-G1 phase and DNA fragmentation. We found that CTD increased gene expression (mRNA) of caspase-3 and -8. Moreover, CTD increased ROS and Ca2+ production and decreased the levels of ∆Ψm. Western blot analysis results showed that CTD increased the expression of cleavage caspase-3 and -8, cytochrome c, Bax and AIF but inhibited the levels of Bcl-xL. CTD promoted ER stress associated protein expression such as GRP78, IRE1α, IRE1β, ATF6α and caspase-4 and it also promoted the expression of calpain 2 and XBP-1, but inhibited calpain 1 that is associated with apoptosis pathways. Based on those observations, we suggest that CTD may be used as a novel anticancer agent for the treatment of lung cancer in the future.

Abstract
To understand the profile of genetic structure of Xianbei and trace its impacts on the formation and development of the minorities from northern China, we analyzed the sequences of the hypervariable segment I (HVS-I, 16.035-16.398) in mtDNA control region of 17 Tuoba Xianbei remains from Shangdu Dongdajing cemetery (Inner Mongolia). Its haplotype diversity and nucleotide diversity were 0.971 ± 0.032 and 0.0184 ± 0.010, respectively, and the haplogroup status presented 29.5% C, 23.5% D4, 17.6% D5, 17.6% A, 5.9% B and 5.9% G. When the data from Qilang Mountain Tuoba remains and other relevant populations were considered, we found that Dongdajing Tuoba Xianbei presented the closest genetic affinity to Qilang Mountain Tuoba Xianbei. Tuoba Xianbei and Murong Xianbei showed a significant differentiation in the maternal lineages. Tuoba Xianbei may contribute to the gene pool of some northern minorities, and it may mix with Xiongnu in northern China.

Abstract
Many anticancer drugs are obtained from phytochemicals and natural products. However, some phytochemicals have mutagenic effects. Safrole, a component of Piper betle inflorescence, has been reported to be a carcinogen. We have previously reported that safrole induced apoptosis in human oral cancer cells in vitro and inhibited the human oral tumor xenograft growth in vivo. Until now, there is no information addressing if safrole promotes immune responses in vivo. To evaluate whether safrole modulated immune function, BALB/c mice were intraperitoneally injected with murine myelomonocytic WEHI-3 leukemia cells to establish leukemia and then were treated with or without safrole at 4 and 16 mg/kg. Animals were sacrificed after 2 weeks post-treatment with safrole for examining the immune cell populations, phagocytosis of macrophages and the natural killer (NK) cells' cytotoxicity. Results indicated that safrole increased the body weight, and decreased the weights of spleen and liver in leukemic mice. Furthermore, safrole promoted the activities of macrophages phagocytosis and NK cells' cytotoxicity in leukemic mice when compared with untreated leukemic mice. After determining the cell marker population, we found that safrole promoted the levels of CD3 (T cells), CD19 (B cells) and Mac-3 (macrophages), but it did not affect CD11b (monocytes) in leukemic mice. In conclusion, safrole altered the immune modulation and inhibited the leukemia WEHI-3 cells in vivo.

Abstract
Wear particles are phagocytosed by macrophages and other inflammatory cells,
resulting in cellular activation and release of proinflammatory factors, which
cause periprosthetic osteolysis and subsequent aseptic loosening, the most
common causes of total joint arthroplasty failure. During this pathological
process, tumor necrosis factor-alpha (TNF-α) plays an important role in
wear-particle-induced osteolysis. In this study, recombination adenovirus (Ad)
vectors carrying both target genes [TNF-α small interfering RNA (TNF-α-siRNA)
and bone morphogenetic protein 2 (BMP-2)] were synthesized and transfected into
RAW264.7 macrophages and pro-osteoblastic MC3T3-E1 cells, respectively. The
target gene BMP-2, expressed on pro-osteoblastic MC3T3-E1 cells and silenced by
the TNF-α gene on cells, was treated with titanium (Ti) particles that were
assessed by real-time PCR and Western blot. We showed that recombinant
adenovirus (Ad-siTNFα-BMP-2) can induce osteoblast differentiation when treated
with conditioned medium (CM) containing RAW264.7 macrophages challenged with a
combination of Ti particles and Ad-siTNFα-BMP-2 (Ti-ad CM) assessed by alkaline
phosphatase activity. The receptor activator of nuclear factor-κB ligand was
downregulated in pro-osteoblastic MC3T3-E1 cells treated with Ti-ad CM in
comparison with conditioned medium of RAW264.7 macrophages challenged with Ti
particles (Ti CM). We suggest that Ad-siTNFα-BMP-2 induced osteoblast
differentiation and inhibited osteoclastogenesis on a cell model of a Ti
particle-induced inflammatory response, which may provide a novel approach for
the treatment of periprosthetic osteolysis.

Abstract
This research focused on a Chinese herb medicine, Solanum lyratum Thunb (Solanaceae) by ethanol extracts (SLE) for investigating the molecular anticancer mechanism in vitro for exploring the means of cell death through the effects on mitochondrial function. We found that SLE induced cytotoxic effects in human osteosacroma U-2 OS cells, and these effects include cell morphological changes, a decrease of the percentage of viable cells and induction of apoptosis. The results suggest that cell death induced by SLE is closely related to apoptosis based on the observations of DAPI staining and sub-G1 phase in U-2 OS cells. Flow cytometric assays also showed that SLE promoted the production of reactive oxygen species and nitric oxide but decreased the levels of mitochondrial membrane potential and promoted the activations of caspase-8 and -9 in U-2 OS cells. SLE inhibited the level of Bcl-2 but promoted the Bax level, and both proteins led to the release of cytochrome c from mitochondria to cytosol and activation of caspase-9 and -3, resulting in the apoptotic death which is mediated through the mitochondrial pathway. Taken together, SLE was demonstrated to be effective in killing U-2 OS osteosacroma cells via the ROS-promoted and mitochondria- and caspase-dependent apoptotic pathways.

Abstract
The cytostatic drug from natural products has acted as a chemotherapeutic agent used in treatment of a wide variety of cancers. Apigenin, a type of flavonoid, exhibits anticancer actions, but there is no report to show that apigenin induced apoptosis in osteosarcoma cells. The aim of this study was to investigate the effects of apigenin on U-2 OS human osteosarcoma cells and clarify that the apigenin-induced apoptosis-associated signals. The cytotoxic effects of apigenin were examined by culturing U-2 OS cells with or without apigenin. The percentage of viable cells via PI staining, apoptotic cells, productions of ROS and Ca²⁺, and the level of mitochondrial membrane potential (ΔΨm) were assayed by flow cytometry. The levels of apoptosis-related proteins were measured by immunoblotting. Results indicated that apigenin significantly decreased cell viability. Apigenin effectively induced apoptosis through the activations of caspase-3, -8, -9, and BAX and promoted the release of AIF in U-2 OS cells. In nude mice bearing U-2 OS xenograft tumors, apigenin inhibited tumor growth. In conclusion, apigenin has anticancer properties for induction of cell apoptosis in U-2 OS cells and suppresses the xenograft tumor growth. These findings offer novel information that apigenin possibly possesses anticancer activity in human osteosarcoma.

Abstract
Norcantharidin (NCTD) is one of the ingredients of blister beetles which have been used in Chinese medicine for a long time. The purpose of this study was to investigate the inhibitory effects of NCTD on TSGH 8301 human bladder cancer cells in vitro and the mechanisms through which it exerts its anticancer action. Cell morphological analysis was performed using a phase-contrast microscope. The percentage of viable cells, cell cycle distribution, sub-G1 phase (apoptosis), reactive oxygen species (ROS) production and the levels of mitochondrial membrane potential (∆Ψ(m)) were analyzed by flow cytometry. DNA condensation and damage were determined by DAPI staining and comet assay. Apoptosis-associated protein level changes in TSGH 8301 cells following exposure to NCTD were examined, measured and determined by western blotting. Analysis of protein translocation was conducted by immunostaining and confocal laser microscopy. The results indicated that NCTD promoted cytotoxic effects, including the induction of cell morphological changes and the decrease in the percentage of viability, the induction of S-phase arrest as well as sub-G1 phase (apoptosis) in TSGH 8301 cells. The activities of caspase-3 and -9 were upregulated following NCTD treatment. Western blotting indicated that NCTD upregulated Fas, FasL, Bax, Bid, cytochrome c, caspase-3, -8 and -9 that led to the induction of apoptosis through the Fas extrinsic pathway. Furthermore, NCTD induced AIF and Endo G that were released from mitochondria to induce apoptosis through the mitochondrial-independent pathway. NCTD upregulated ROS production, downregulated ∆Ψ(m) and ERK, JNK, p38 protein kinases in TSGH 8301 cells. These findings suggest that NCTD triggers apoptosis in TSGH 8301 human bladder cancer cells via the Fas receptor, activation of the caspse-8, -9 and -3, mitochondrial-dependent and -independent pathways. NCTD may be useful for developing new therapeutic regimens for the treatment of bladder cancer.

Abstract
To elevate chemo-resistance of human cancer cells is a major obstacle in the treatment and management of malignant cancers. Diallyl sulfide (DAS), diallyl disulfide (DADS) and diallyl trisulfide (DATS) are presented in the Alliaceae family particularly in garlic. Although DAS, DADS and DATS have been shown to exhibit anticancer activities, there is little information on effects of these compounds on drug resistant genes in human colon cancer cells in vitro and in vivo. Herein, we are the first to show that DAS, DADS and DATS at 25 μM for 24-h and 48-h incubations promoted expression of drug resistant genes in colo 205 human colon cancer cells. In vitro experiments indicated that DATS promoted gene expression of multidrug resistant 1 (Mdr1) (p<0.05), and DAS and DADS promoted MRP3 gene expression and DATS alone stimulated gene expression of multidrug resistance-associated protein-1 (MRP1) (p<0.05) in colo 205 cells. In vivo studies demonstrated that DADS and DATS induced Mdr1 and MRP1 gene expression (p<0.05). DADS promoted MRP3 gene expression (p<0.05) as well as DADS and DATS increased MRP4 and MRP6 gene expression (p<0.05) in the colo 205 xenograft mice. Based on our in vitro and in vivo results, diallyl polysulfides (DAS, DADS and DATS) affected the gene expression of the multidrug resistance in colo 205 human colon cancer cells in vitro and in vivo.

Abstract
Safrole, a component of Piper betle inflorescence, is a carcinogen which has been demonstrated to induce apoptosis on human oral cancer HSC-3 cells in vitro and to inhibit HSC-3 cells in xenograft tumor cells in vivo. In our previous study, safrole promoted phagocytosis by macrophages and natural killer cell cytotoxicity in normal BALB/c mice. The cytotoxic effects of safrole on HL-60 cells were investigated by using flow cytometric analysis, comet assay, 4',6-diamidino-2-phenylindole (DAPI) staining, western blotting and confocal laser microscopy. The obtained results indicate that safrole induced a cytotoxic response through reducing the percentage of viable cells and induction of apoptosis in HL-60 cells in a dose-dependent manner. DAPI staining and comet assay also showed that safrole induced apoptosis (chromatin condensation) and DNA damage in HL-60 cells. The flow cytometric assay showed that safrole increased the production of reactive oxygen species (ROS) and Ca(2+) and reduced the mitochondrial membrane potential in HL-60 cells. Safrole enhanced the levels of the pro-apoptotic protein BAX, inhibited those of the anti-apoptotic protein BCL-2 and promoted the levels of apoptosis-inducing factor (AIF) and endonuclease G (Endo G) in HL-60 cells. Furthermore, safrole promoted the expression of glucose-regulated protein 78 (GRP78), growth arrest- and DNA damage-inducible gene 153 (GADD153) and of activating transcription factor 6α (ATF-6α). Based on these findings, we suggest that safrole-induced apoptosis in HL-60 cells is mediated through the ER stress and intrinsic signaling pathways.

Abstract
In this study, we examined the effects of several plant-derived natural compounds on head and neck squamous cell carcinoma (HNSCC) cells. The results revealed that (-)-epigallocatechin gallate (EGCG) demonstrated the most efficient cytotoxic effects on HNSCC cells. We then investigated the underlying molecular mechanism for the potent proapoptotic effect of EGCG on HNSCC. Cell apoptosis was observed in the EGCG-treated SAS and Cal-27 cells in a time- and dose-dependent manner. In concert with the caspase-8 activation by EGCG, an enhanced expression in functional Fas/CD95 was identified. Consistent with the increased Fas/CD95 expression, a drastic decrease in the Tyr705 phosphorylation of STAT3, a known negative regulator of Fas/CD95 transcription, was shown within 15 min in the EGCG-treated cells, leading to downregulation of the target gene products of STAT3, such as bcl-2, vascular endothelial growth factor (VEGF), mcl-1, and cyclin D1. An overexpression in STAT3 led to resistance to EGCG, suggesting that STAT3 was a critical target of EGCG. Besides inhibiting constitutive expression, EGCG also abrogated the interleukin-6 (IL-6)-induced JAK/STAT3 signaling and further inhibited IL-6-induced proliferation on HNSCC cells. In comparison with apigenin, curcumin, and AG490, EGCG was a more effective inhibitor of IL-6-induced proliferation on HNSCC cells. Overall, our results strongly suggest that EGCG induces Fas/CD95-mediated apoptosis through inhibiting constitutive and IL-6-induced JAK/STAT3 signaling. This mechanism may be partially responsible for EGCG's ability to suppress proliferation of HNSCC cells. These findings provide that EGCG may be useful in the chemoprevention and/or treatment of HNSCC.
