J Cancer Res Clin Oncol 2024; 150:345. [PMID: 38981872 PMCID: PMC11233420 DOI: 10.1007/s00432-024-05860-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Accepted: 06/19/2024] [Indexed: 07/11/2024]
Abstract
BACKGROUND Endometrial cancer (EC) is the sixth most frequent cancer in women worldwide and has higher fatality rates. The pathophysiology of EC is complex, and there are currently no reliable methods for diagnosing and treating the condition. Long non-coding RNA (lncRNA), according to mounting evidence, is vital to the pathophysiology of EC. HOTAIR is regarded as a significant prognostic indicator of EC. ZBTB7A decreased EC proliferation and migration, according to recent studies, however the underlying mechanism still needs to be clarified. METHODS The research utilized RT-qPCR to measure HOTAIR expression in clinical EC tissues and various EC cell lines. Kaplan-Meier survival analysis was employed to correlate HOTAIR levels with patient prognosis. Additionally, the study examined the interaction between ZBTB7A and HOTAIR using bioinformatics tools and ChIP assays. The experimental approach also involved manipulating the expression levels of HOTAIR and ZBTB7A in EC cell lines and assessing the impact on various cellular processes and gene expression. RESULTS The study found significantly higher levels of HOTAIR in EC tissues compared to adjacent normal tissues, with high HOTAIR expression correlating with poorer survival rates and advanced cancer characteristics. EC cell lines like HEC-1 A and KLE showed higher HOTAIR levels compared to normal cells. Knockdown of HOTAIR in these cell lines reduced proliferation, angiogenesis, and migration. ZBTB7A was found to be inversely correlated with HOTAIR, and its overexpression led to a decrease in HOTAIR levels and a reduction in malignant cell behaviors. The study also uncovered that HOTAIR interacts with ELAVL1 to regulate SOX17, which in turn activates the Wnt/β-catenin pathway, promoting malignant behaviors in EC cells. CONCLUSION HOTAIR is a critical regulator in EC, contributing to tumor growth and poor prognosis. Its interaction with ZBTB7A and regulation of SOX17 via the Wnt/β-catenin pathway underlines its potential as a therapeutic target.

Abstract
Long noncoding RNAs (lncRNAs) are widely dysregulated in cancer, yet their functional roles in cancer hallmarks remain unclear. We employ pooled CRISPR deletion to perturb 831 lncRNAs detected in KRAS-mutant non-small cell lung cancer (NSCLC) and measure their contribution to proliferation, chemoresistance, and migration across two cell backgrounds. Integrative analysis of these data outperforms conventional "dropout" screens in identifying cancer genes while prioritizing disease-relevant lncRNAs with pleiotropic and background-independent roles. Altogether, 80 high-confidence oncogenic lncRNAs are active in NSCLC, which tend to be amplified and overexpressed in tumors. A follow-up antisense oligonucleotide (ASO) screen shortlisted two candidates, Cancer Hallmarks in Lung LncRNA 1 (CHiLL1) and GCAWKR, whose knockdown consistently suppressed cancer hallmarks in two- and three-dimension tumor models. Molecular phenotyping reveals that CHiLL1 and GCAWKR control cellular-level phenotypes via distinct transcriptional networks. This work reveals a multi-dimensional functional lncRNA landscape underlying NSCLC that contains potential therapeutic vulnerabilities.

Acute exposure to microcystin-LR induces hepatopancreas toxicity in the Chinese mitten crab (Eriocheir sinensis). Arch Toxicol 2021; 95:2551-2570. [PMID: 33977345 DOI: 10.1007/s00204-021-03061-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 04/28/2021] [Indexed: 10/21/2022]
Abstract
The Chinese mitten crab is an important economic species in the Chinese aquaculture industry due to its rich nutritional value and distinct flavor. The hepatopancreas is a popular edible part of the Chinese mitten crab, and therefore, hepatopancreatic health directly determines its quality. However, a large-scale outbreak of hepatopancreatic necrosis syndrome ("Shuibiezi" disease in Chinese), which is caused by abiotic agents correlated with cyanobacteria bloom outbreaks, adversely affects the Chinese mitten crab breeding industry. Cyanobacterial blooms that occur in high-density farming ponds can produce microcystin-LR (MC-LR), which is hepatotoxic in fish and mammals. Hepatopancreas toxicity of MC-LR (0, 25, 50 and 75 μg/kg) was investigated after 48 h of exposure. The MC-LR can cause hepatopancreatic injury by inducing hepatopancreatic structural damage, subcellular structural changes, and cell apoptosis, followed by enhanced lipid peroxidase, reactive oxygen species, and apoptosis-related enzyme (Caspase 3, 8, and 9) activities. These in turn promote gene and protein expression of apoptosis-associated proteases (Caspase 3, 7, and 8, Bcl-2, and Bax), and alter antioxidant system responses (superoxide dismutase, glutathione S-transferase, glutathione peroxidase, glutathione reductase activities, and glutathione content). The present study is the first report on MC-LR hepatotoxicity in the Chinese mitten crab and confirms hepatopancreas toxicity, providing a theoretical basis for enhancing MCs resistance and developing preventive and curative measures against hepatopancreatic disease in the Chinese mitten crab breeding industry.

DRUG DESIGN DEVELOPMENT AND THERAPY 2021; 15:125-140. [PMID: 33469265 PMCID: PMC7811378 DOI: 10.2147/dddt.s269901] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 12/09/2020] [Indexed: 01/15/2023]
Abstract
Background As a natural compound extracted from a variety of hot peppers, capsaicin has drawn increasing attention to its anti-cancer effects against multiple human cancers including breast cancer. FBI-1 is a major proto-oncogene negatively regulating the transcription of many tumor suppressor genes, and plays a vital role in tumorigenesis and progression. However, whether FBI-1 is involved in capsaicin-induced breast cancer suppression has yet to be ascertained. This study aimed to investigate the effects of capsaicin on proliferation and apoptosis and its association with FBI-1 expression in breast cancer. Methods CCK-8 and morphological observation assay were employed to detect cell proliferation. Flow cytometry and TUNEL assay were conducted to detect cell apoptosis. RNA interference technique was used to overexpress or silence FBI-1 expression. qRT-PCR and/or Western blot analysis were applied to detect the protein expression of FBI-1, Ki-67, Bcl-2, Bax, cleaved-Caspase 3, Survivin and NF-κB p65. Xenograft model in nude mice was established to assess the in vivo effects. Results Capsaicin significantly inhibited proliferation and induced apoptosis in breast cancer in vitro and in vivo, along with decreased FBI-1, Ki-67, Bcl-2 and Survivin protein expression, increased Bax protein expression and activated Caspase 3. Furthermore, FBI-1 overexpression obviously attenuated the capsaicin-induced anti-proliferation and pro-apoptosis effect, accompanied with the above-mentioned proteins reversed, whereas FBI-1 silencing generated exactly the opposite response. In addition, as a target gene of FBI-1, NF-κB was inactivated by p65 nuclear translocation suppressed with capsaicin treatment, which was perceptibly weakened with FBI-1 overexpression or enhanced with FBI-1 silencing. Conclusion This study reveals that FBI-1 is closely involved in capsaicin-induced anti-proliferation and pro-apoptosis of breast cancer. The underlying mechanism may be related to down-regulation of FBI-1-mediated NF-κB pathway. Targeting FBI-1 with capsaicin may be a promising therapeutic strategy in patients with breast cancer.

Abstract
Backgroud ZBTB protein is an important member of the C2H2 zinc finger protein family. As a transcription factor, it is widely involved in the transcriptional regulation of genes, cell proliferation, differentiation, and apoptosis. The ZBTB7A has been largely linked to different kinds of tumors due to its diverse function. However, the value for ZBTB7A in uterine corpus endometrial carcinoma (UCEC) is unclear. Methods In our work, we assessed the importance of ZBTB7A in UCEC. Firstly, Using Oncomine and Tumor Immunoassay Resource (TIMER) databases to evaluate the expression of ZBTB7A. Secondly, we explored the co-expression network of ZBTB7A through the cBioPortal online tool, Metascape, and LinkedOmics. TIMER was also used to explore the relationship between ZBTB7A and tumor immune invasion, and to detect the correlation between the ZBTB7A and the marker genes related to immune infiltration. Finally, CCK8, migration, ChIP assays were introduced to partly validate ZBTB7A function in endometrial cancer cells. Results We found the ZBTB7A expression in TIMER was associated with various cancers, especially UCEC. The decreased expression of ZBTB7A was markedly related to the stage and prognosis of UCEC. Furthermore, ZBTB7A was also related to the expression of various immune markers such as Neutrophils, Dendritic cell, T cell (general), Th1, Th2, and Treg. Finally, we verified that ZBTB7A repressed E2F4 transcription and inhibited cells proliferation and migration. These results indicate that ZBTB7A may play a vital role in regulating immune cell infiltration in UCEC, and is a valuable prognostic marker. Conclusions In summary, we demonstrate that ZBTB7A is notably downregulated in UCEC, plays a vital role in regulating immune cell infiltration, possesses diagnostic and prognostic values and attenuates E2F4 transcription and cell proliferation, migration in vitro.

Abstract
It has been generally confirmed that zinc finger and BTB domain containing 7A (ZBTB7A) plays an important role in the occurrence and progression of malignant tumours, but the promotion or inhibition effect is related to tumour type. The mechanism between ZBTB7A and breast cancer is not well understood, so further research is needed. In this study, we first investigated the expression of ZBTB7A in tissue samples of clinical breast cancer patients, MDA-MB-231, MCF-7 and MCF-10A cells. Second, we overexpressed the ZBTB7A in MCF-7 cells and silenced the ZBTB7A in MDA-MB-231 cells using lentivirus transfection technology, respectively, and verified the effect of ZBTB7A on migration and invasion of breast cancer cell lines through in vitro cell function experiments, such as wound-healing assay, migration and invasion assay, quantitative real time reverse transcriptase (qRT-PCR) and western blot. Then, the correlation between the above influences, epithelial-mesenchymal transition (EMT) and NF-κB was analysed. Finally, in vivo tumour transplantation model in nude mice was established to verified the effect of ZBTB7A on metastasis of breast cancer MDA-MB-231 cells. In conclusion, ZBTB7A is highly expressed in cancer tissue, breast cancer cell line MDA-MB-231 and MCF-7. Meanwhile, the high expression of ZBTB7A may promote cell migration, invasion and tumour metastasis, which may be related to EMT events by regulating NF-κB.

Abstract
Transcription factors (TFs) consisting of zinc fingers combined with BTB (for broad-complex, tram-track, and bric-a-brac) domain (ZBTB) are a highly conserved protein family that comprises a multifunctional and heterogeneous group of TFs, mainly modulating cell developmental events and cell fate. LRF/ZBTB7A, in particular, is reported to be implicated in a wide variety of physiological and cancer-related cell events. These physiological processes include regulation of erythrocyte maturation, B/T cell differentiation, adipogenesis, and thymic insulin expression affecting consequently insulin self-tolerance. In cancer, LRF/ZBTB7A has been reported to act either as oncogenic or as oncosuppressive factor by affecting specific cell processes (proliferation, apoptosis, invasion, migration, metastasis, etc) in opposed ways, depending on cancer type and molecular interactions. The molecular mechanisms via which LRF/ZBTB7A is known to exert either physiological or cancer-related cellular effects include chromatin organization and remodeling, regulation of the Notch signaling axis, cellular response to DNA damage stimulus, epigenetic-dependent regulation of transcription, regulation of the expression and activity of NF-κB and p53, and regulation of aerobic glycolysis and oxidative phosphorylation (Warburg effect). It is a pleiotropic TF, and thus, alterations to its expression status become detrimental for cell survival. This review summarizes its implication in different cellular activities and the commonly invoked molecular mechanisms triggered by LRF/ZBTB7A’s orchestrated action.

Teroxirone suppresses growth and motility of human hepatocellular carcinoma cells. Biomed Pharmacother 2018; 99:997-1008. [PMID: 29653488 DOI: 10.1016/j.biopha.2018.01.157] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2017] [Revised: 01/15/2018] [Accepted: 01/29/2018] [Indexed: 02/07/2023] Open
Abstract
AIMS The prevalent human hepatocellular carcinoma (HCC) is a leading cause of global cancer-related mortality. The small molecular weight triepoxide derivative, 1,3,5-triazine-2,4,6(1H,3H,5H)-tri-one-1,3,5-tri-(oxiranylmethyl) (teroxirone), has been proved effective against the proliferation of lung cancer cells. The purpose is to further examine if teroxirone regulate growth and metastatic potential of HCC cells with aims at disclosing more of the reaction mechanisms. MAIN METHODS Measurements of cell viability and flow cytometry were conducted to test sensitivities of teroxirone against HCC cells. The signaling pathway leading to apoptotic death was unraveled by Western blotting analysis. The metastatic progression was evaluated by cell-based phenotype assay that included migration, invasion, gelatin zymography and wound assay. The in vivo drug efficiency was done in immune-deficient mice with the established xenograft tumors. KEY FINDINGS Teroxirone inhibited growth of HCC cells, but not hepatic cells. The drug induced apoptosis in HCC cells bearing mutant p53. Pretreatment of caspase-3 inhibitor restored cell viabilities by suppressing extrinsic pathway-mediated cell death. More experiments suggested that sub-apoptotic concentrations of teroxirone mitigated migration, invasion and wound healing of HCC cells. The drug reduced growth of the xenograft tumors as established in animal models by activating apoptotic death. SIGNIFICANCE The findings asserted that teroxirone is an eligible addition to the existing options as an anticancer agent to eliminate HCC.

Abstract
Regulatory functions of the ubiquitin-proteasome system (UPS) are exercised mainly by the ubiquitin ligases and deubiquitinating enzymes. Degradation of apoptotic proteins by UPS is central to the maintenance of cell health, and deregulation of this process is associated with several diseases including tumors, neurodegenerative disorders, diabetes, and inflammation. Therefore, it is the view that interrogating protein turnover in cells can offer a strategy for delineating disease-causing mechanistic perturbations and facilitate identification of drug targets. In this review, we are summarizing an overview to elucidate the updated knowledge on the molecular interplay between the apoptosis and UPS pathways. We have condensed around 100 enzymes of UPS machinery from the literature that ubiquitinates or deubiquitinates the apoptotic proteins and regulates the cell fate. We have also provided a detailed insight into how the UPS proteins are able to fine-tune the intrinsic, extrinsic, and p53-mediated apoptotic pathways to regulate cell survival or cell death. This review provides a comprehensive overview of the potential of UPS players as a drug target for cancer and other human disorders.

Abstract
Oridonin, the main active constituent of Rabdosia rubescens, is known to exert antitumor activity via the induction of apoptosis in numerous types of human cancer cells. However, the underlying regulatory mechanisms of mitochondrial ROS in oridonin-induced HepG2 apoptosis remain largely unknown, due to limitations of subcellular imaging resolution. Previously, it has been suggested that mitochondria serve a potential role in sensing and signaling cellular redox changes in vital biological processes such as cell death and the abiotic stress response, based on studies involving the mitochondrial-targeted redox-sensitive green fluorescent protein (GFP). To address this, a mitochondrial-targeted Grx1-roGFP2 (mtGrx1-roGFP2) biosensor was implemented to monitor real-time mitochondrial redox changes of HepG2 cells in response to either H2O2/DTT or oridonin/SS31 treatment. It was determined that oridonin caused a perturbation in mitochondrial redox status, which in turn contributed to oridonin-induced apoptosis. Furthermore, a novel mechanism underlying the regulation of mitochondrial redox changes in oridonin-induced HepG2 apoptosis, presumably dependent on PARP cleavage, was proposed. In conclusion, the present study provides evidence in support of mitochondrial redox changes as a potential mediator in the apoptotic activities of oridonin in HepG2 cells, which provides insight into the molecular mechanisms by which mitochondrial redox signaling regulates oridonin-induced apoptosis in cancer therapy, and the development of mitochondria-specific oridonin as a promising novel anticancer therapeutic strategy.

Abstract
Human malignant hepatocellular carcinoma (HCC) is a common tumor, which severely threatens human health and shortens longevity. The poor prognosis of HCC is primarily attributed to distant metastases. C-X-C motif chemokine 10 (CXCL10) regulates the control of several cellular and developmental processes including tumor cell proliferation, apoptosis, and cell metastasis. Previous studies have confirmed that CXCL10 functions as an oncogene in several cancers. However, the expression and biological functions of CXCL10 in HCC, especially with regard to metastasis, need further investigation. In this study, CXCL10 was found to be over expressed in invasive HCC cells and HCC clinical samples. While the over-expression of CXCL10 enhanced migration, invasion, and metastasis of HCC cells in vitro as well as in vivo, silencing of CXCL10 resulted in inhibition of HCC cell metastasis. Further, CXCL10 was found to accelerate epithelial-mesenchymal transition of HCC cells. The microarray analysis indicated that matrix metallopeptidase-2 (MMP-2) functions as a downstream factor of CXCL10. This study demonstrates that CXCL10 partakes in the metastasis of HCC by activating MMP-2 expression.

Abstract
Osteosarcoma is the most common type of solid bone cancer, which is the second leading cause of cancer-related death. Hypoxia is an ordinary phenomenon in solid tumor tissues and can induce cell apoptosis but the specific molecular mechanism remains unclear. In this study, we explored the effect and the molecular mechanism of Transglutaminase 2 (TG2) on cell apoptosis in osteosarcoma U2OS cells under hypoxia. We found the enzymatic activity of TG2 is significantly increased and the expression of TG2 is remarkably up-regulated under hypoxia condition. Cell apoptotic rate is markedly increased upon knockdown of TG2 by siRNA under hypoxia. We further investigated the mechanism of cell apoptosis and found Bax protein is significantly increased after depletion of TG2 under hypoxia. Moreover, our data also show that cytochrome C (Cyt C) is significantly increased in cytoplasm and markedly decreased in mitochondria of U2OS cells after depletion of TG2 under hypoxia. Our results suggest that TG2 can inhibit tumor cell apoptosis through down-regulation of Bax and prevention of release Cyt C from mitochondria into cytoplasm.

Abstract
Placenta-specific protein 1 (Plac1), which is selectively expressed in the placental syncytiotrophoblast in adult normal tissues, plays an essential role in normal placental and embryonic development. Accumulating evidence suggests that enhanced Plac1 expression is closely associated with the progression of human cancer. Whether Plac1 contributes to the pathophysiology of hepatocellular carcinoma (HCC) remains unclear. In the present study, our data revealed that the expression of Plac1 in human HCC tissues was upregulated, which significantly correlated with metastasis of HCC. Knockdown of Plac1 by small interfering RNA (siRNA) in Bel-7402 and HepG2 cells resulted in decreasing tumor cell proliferation and increasing apoptosis, which implied the oncogenic potential of Plac1. Moreover, silencing of Plac1 induced G1 cell cycle arrest through suppression of cyclin D1 and CDK4 expression. Furthermore, depletion of Plac1 repressed epithelial-mesenchymal transition (EMT), with decreased cell migration and invasion, supporting upregulated E-cadherin expression and downregulated vimentin, twist and snail expression that characterize EMT. Further study suggested that decreased Plac1 expression attenuated the phosphorylation of Akt. These findings have uncovered that Plac1 plays a pivotal role in the progression of HCC, and may serve as a novel therapeutic target for HCC.

Abstract
BACKGROUND Pokemon, a master oncogene crucial for the tumorigenicity and progression of a variety of cancers, has been demonstrated to enhance the proliferation and survival of hepatocellular carcinoma (HCC). However, the contribution of Pokemon to the invasiveness of HCC has not yet been studied. METHODS In this study, we employed HCC cells to investigate the role of Pokemon in the invasion of HCC with multidisciplinary approaches. RESULTS Pokemon overexpression was found to be closely associated with invasion and intrahepatic metastasis of HCC in clinical specimens. Suppression of Pokemon attenuated the invasion of HCC cells by in vitro transwell and wound-healing assays. Myocyte enhancer factor 2D (MEF2D), an oncogene that can promote the invasiveness of HCC, was found to be underexpressed during Pokemon silencing in HCC cells. Restoration of MEF2D abolished the effect of Pokemon downregulation on the migration of HCC cells. Further experiments verified that Pokemon binds two putative recognition sites located within the upstream region of the MEF2D promoter and enhances its transcription. The association between Pokemon and MEF2D was further confirmed in HCC specimens. Animal experiments further confirmed that Pokemon downregulation attenuated the metastasis of HCC cells in mice. CONCLUSION Collectively, Pokemon was found to enhance the migration and invasion of HCC by increasing MEF2D expression. Thus, targeting Pokemon and MEF2D may be an effective strategy to suppress the metastasis of HCC.

Abstract
Gallic acid (3,4,5-trihydroxybenzoic acid; GA) is a naturally occurring plant polyphenol, isolated from water caltrop, which has been reported to exert anticancer effects. The present study investigated the antiproliferative effects of GA on the HepG2 and SMMC-7721 human hepatocellular carcinoma (HCC) cell lines using MTT and colony formation assays. In particular, the underlying mechanism of GA-induced apoptosis in SMMC-7721 cells was studied in vitro by flow cytometry and western blotting. The results of the present study indicated that GA was capable of inhibiting the proliferation of HepG2 and SMMC-7721 cells in a time- and dose-dependent manner, as well as inducing the apoptosis of SMMC-7721 cells. GA induced caspase-3, caspase-9 and reactive oxygen species activity, elevated the expression of apoptosis regulator Bcl-2-like protein 4 and reduced the mitochondrial membrane potential in SMMC-7721 cells. When compared with HL-7702 normal human hepatocytes, GA demonstrated selective toxicity for HCC cells. In conclusion, GA is able to induce apoptosis in SMMC-7721 cells in vitro via mitochondrial-mediated pathways, and may possess the potential to be a novel therapeutic compound for use in the treatment of HCC.

Abstract
The aim of the present study was to investigate the association between the apoptosis phenomenon in the MG-63 osteosarcoma cell line, and transglutaminase II (TG2) expression. The relationship between the anti-apoptotic mechanism of TG2 and the expression of cytochrome c as well as caspase-3 under hypoxic conditions was also verified. A hypoxic culture of MG-63 cells was prepared. The hypoxia and TG2 siRNA hypoxia groups were established, and the cultures were incubated for 12 h under hypoxic conditions. TG2 activity, TG2 protein expression and its mRNA level were investigated. Cytochrome c and caspase-3 protein levels in the TG2 nucleus and cytoplasm were measured. The apoptotic rate was also monitored. The results showed that TG2 activity, TG2 protein expression and its mRNA level in the hypoxia group were significantly higher than those of the siRNA hypoxia group. The results showed statistically insignificant differences (P<0.05). By contrast, a comparison of the two groups in the cytoplasm yielded no statistically significant differences (P>0.05). Cytochrome c and caspase-3 protein levels in the hypoxia group were significantly higher than those of the TG2 siRNA hypoxia group. The results showed statistically significant differences (P<0.05). By contrast, the protein levels in the cytoplasm were significantly lower than those of the TG2 siRNA hypoxia group, with differences being statistically significant (P<0.05). The differences in apoptotic rates between the hypoxia and TG2 siRNA hypoxia groups were also statistically significant (P<0.05). Under hypoxic conditions, a high TG2 expression inhibited the apoptosis of the MG-63 osteosarcoma cell line. This effect was probably associated with its suppressive activity on the transportation of cytochrome c and caspase-3 from nucleus to cytoplasm.

Abstract
MicroRNAs have been reported to play key roles in various human cancers, including gastric cancer. However, understanding of the expression of miR-100 and its regulatory mechanisms in human gastric cancer remains elusive. In this study, we reveal that miR-100 is downregulated in gastric cancer samples and gastric cancer cell lines. Furthermore, lower miR-100 expression was found in primary gastric cancer samples with lymphatic metastasis compared to those without lymphatic metastasis. Overexpression of miR-100 suppressed tumor growth in vivo and inhibited gastric cancer invasion and metastasis in vitro and in vivo. Furthermore, we demonstrated that miR-100 reduced gastric cancer aggressiveness by directly targeting ZBTB7A. Knockdown of ZBTB7A by siRNA disrupted gastric cancer progression by impairing tumor invasion and metastasis. High expression of ZBTB7A was significantly correlated with poorer prognosis in gastric cancer patients. Our results also showed that the transcription factor CCAAT/enhancer-binding protein alpha (C/EBPα) could induce the expression of miR-100 by binding to the putative promoter region of miR-100. This study demonstrated that miR-100 could be induced by C/EBPα and may act as a tumor suppressor gene by inhibiting ZBTB7A.

Abstract
Hepatocellular carcinoma (HCC) is a deadly human malignant tumor that is among the most common cancers in the world, especially in Asia. Hepatitis B virus (HBV) infection has been well established as a high risk factor for hepatic malignance. Studies have shown that Pokemon is a master oncogene for HCC growth, suggesting it as an ideal therapeutic target. However, efficient delivery system is still lacking for Pokemon targeting treatment. In this study, we used core proteins of HBV, which is modified with RGD peptides, to construct a biomimetic vector for the delivery of Pokemon siRNAs (namely, RGD-HBc-Pokemon siRNA). Quantitative PCR and Western blot assays revealed that RGD-HBc-Pokemon siRNA possessed the highest efficiency of Pokemon suppression in HCC cells. In vitro experiments further indicated that RGD-HBc-Pokemon-siRNA exerted a higher tumor suppressor activity on HCC cell lines, evidenced by reduced proliferation and attenuated invasiveness, than Pokemon-siRNA or RGD-HBc alone. Finally, animal studies demonstrated that RGD-HBc-Pokemon siRNA suppressed the growth of HCC xenografts in mice by a greater extent than Pokemon-siRNA or RGD-HBc alone. Based on the above results, Pokemon siRNA delivery mediated by RGD-modified HBV core protein was shown to be an effective strategy of HCC gene therapy.

Abstract
Hepatocellular carcinoma (HCC) is a type of human malignant tumor occurring in hepatic tissues with high mortality. Patients benefit little from current therapeutic modalities, at least partially due to the lack of complete elucidation of molecular network regulating HCC. miR-125 and Pokemon are well-recognized tumor suppressor and oncogenes for HCC, respectively. However, the underlying mechanism by which the two genes exert their functions and the relationship between miR-125 and Pokemon is still unexplored yet. In this study, we found that there is an inverse association between miR-125 and Pokemon expression levels in HCC specimen and cell lines. Online database mining indicated that there are three putative mRNA recognition elements (MREs) of miR-125 within 3' untranslated region (3'UTR) of Pokemon. MREs of miR-125 confer the expression of luciferase with a miR-125-dependent fashion. The alteration in miR-125 abundance regulates the expression of Pokemon at both protein and mRNA levels. Overexpression of Pokemon is able to abrogate the inhibitory effect of miR-125 on HCC progression. Further study showed that Pokemon inhibits the expression of miR-125 by binding of recognition sites within its promoter. In conclusion, we found that there is an auto-regulatory circuit consisting of miR-125 and Pokemon, which promotes the progression of HCC and may be a promising therapeutic target in clinical HCC treatment.

Abstract
The deregulation of cell polarity or cytoskeletal regulators is a common occurrence in human epithelial cancers. Moreover, there is accumulating evidence in human epithelial cancer that BTB-ZF genes, such as Bcl6 and ZBTB7A, are oncogenic. From our previous studies in the vinegar fly, Drosophila melanogaster, we have identified a cooperative interaction between a mutation in the apico-basal cell polarity regulator Scribble (Scrib) and overexpression of the BTB-ZF protein Abrupt (Ab). Herein, we show that co-expression of ab with actin cytoskeletal regulators, RhoGEF2 or Src64B, in the developing eye-antennal epithelial tissue results in the formation of overgrown amorphous tumours, whereas ab and DRac1 co-expression leads to non-cell autonomous overgrowth. Together with ab, these genes affect the expression of differentiation genes, resulting in tumours locked in a progenitor cell fate. Finally, we show that the expression of two mammalian genes related to ab, Bcl6 and ZBTB7A, which are oncogenes in mammalian epithelial cancers, significantly correlate with the upregulation of cytoskeletal genes or downregulation of apico-basal cell polarity neoplastic tumour suppressor genes in colorectal, lung and other human epithelial cancers. Altogether, this analysis has revealed that upregulation of cytoskeletal regulators cooperate with Abrupt in Drosophila epithelial tumorigenesis, and that high expression of human BTB-ZF genes, Bcl6 and ZBTB7A, shows significant correlations with cytoskeletal and cell polarity gene expression in specific epithelial tumour types. This highlights the need for further investigation of the cooperation between these genes in mammalian systems.

Abstract
Hepatocellular carcinoma (HCC) is one of the most deadly human malignancy, and frequent invasion and metastasis is closely associated with its poor prognosis. However, the molecular mechanism underlying HCC invasion is still not completely elucidated. Pokemon is a well-established oncogene for HCC growth, but its contribution to HCC invasion has not been studied yet. In this paper, Pokemon was found to be overexpressed in MHCC-97H HCC cell line, which possesses higher invasiveness. Downregulation of Pokemon abolished the invasion of MHCC-97H HCC cell lines. Pokemon overexpression was able to enhance the invasion of MHCC-97L cells with lower invasiveness. MEF2D, an oncogene promoting the invasion of HCC cells, was further detected to be upregulated and downregulated when Pokemon was overexpressed and silenced, respectively. Online database analysis indicated that one Pokemon recognition site was located within the promoter of MEF2D. Chromatin co-precipitation, luciferase, and qPCR assays all proved that Pokemon can promote the expression of MEF2D in HCC cells. Restoration of MEF2D expression can prevent the impaired invasion of HCC cells with Pokemon silencing, while suppression of MEF2D abolished the effect of Pokemon overexpression on HCC invasion. More interestingly, MEF2D was also found to increase the transcription of Pokemon by binding myocyte enhancer factor 2 (MEF2) sites within its promoter region, implying an auto-regulatory circuit consisting of these two oncogenes that can promote HCC invasion. Our findings can contribute to the understanding of molecular mechanism underlying HCC invasion, and provided evidence that targeting this molecular loop may be a promising strategy for anti-invasion therapy.

Abstract
AIM: To investigate the effect of gambogic acid (GA) on apoptosis in the HT-29 human colon cancer cell line.
METHODS: H-29 cells were used for in vitro experiments in this study. Relative cell viability was assessed using MTT assays. Cell apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling and Hoechst 33342 staining, and quantified by flow cytometry. Cellular ultrastructure was observed by transmission electron microscopy. Real-time PCR and Western blot analyses were used to evaluate gene and protein expression levels. For in vivo experiments, BALB/c nude mice received subcutaneous injections of HT-29 cells in the right armpit. When well-established xenografts were palpable with a tumor size of 75 mm3, mice were randomly assigned to a vehicle (negative) control, positive control or GA treatment group (n = 6 each). The animals in the treatment group received one of three dosages of GA (in saline; 5, 10 or 20 mg/kg) via the caudal vein twice weekly, whereas animals in the negative and positive control groups were given equal volumes of 0.9% saline or 10 mg/kg docetaxel, respectively, via the caudal vein once weekly.
RESULTS: The cell viability assay showed that GA inhibited proliferation of HT-29 cells in a dose- and time-dependent manner after treatment with GA (0.00, 0.31, 0.62, 1.25, 2.50, 5.00 or 10.00 μmol/L) for 24, 48 or 72 h. After 48 h, the percentage of apoptotic cells in cells treated with 0.00, 1.25, 2.50 and 5.00 μmol/L GA was 1.4% ± 0.3%, 9.8% ± 1.2%, 25.7% ± 3.3% and 49.3% ± 5.8%, respectively. Ultrastructural analysis of HT-29 cells treated for 48 h with 2.5μmol/L GA revealed apoptotic bodies and condensed and fragmented nuclei. Levels of caspase-8, -9 and -3 mRNAs were significantly increased after treatment with GA (1.25, 2.50 or 5.00 μmol/L) for 48 h (P < 0.05 for all). Protein levels of apoptosis-related factors Fas, FasL, FADD, cytochrome c, and Apaf-1 were increased in GA-treated cells, whereas levels of pro-caspase-8, -9 and -3 were significantly decreased (P < 0.05 for all). Furthermore, GA significantly and dose-dependently inhibited the growth of HT-29 tumors in a mouse xenograft model (P < 0.05).
CONCLUSION: GA inhibits HT-29 proliferation via induction of apoptosis. The anti-cancer effects are likely mediated by death receptor (extrinsic) and mitochondrial (intrinsic) pathways.

Abstract
Photodynamic therapy (PDT) is a promising antitumor treatment that is based on the photosensitizers that inhibit cancer cells by yielding reactive oxygen species (ROS) after irradiation of light with specific wavelengths. As a potential photosensitizer, titanium dioxide (TiO2) exhibits minimal dark cytotoxicity and excellent ultraviolet (UV) light triggered cytotoxicity, but is challenged by the limited tissue penetration of UV light. Herein, a novel near-infrared (NIR) light activated photosensitizer for PDT based on TiO2-coated upconversion nanoparticle (UCNP) core/shell nanocomposites (UCNPs@TiO2 NCs) is designed. NaYF4:Yb(3+),Tm(3+)@NaGdF4:Yb(3+) core/shell UCNPs can efficiently convert NIR light to UV emission that matches well with the absorption of TiO2 shells. The UCNPs@TiO2 NCs endocytosed by cancer cells are able to generate intracellular ROS under NIR irradiation, decreasing the mitochondrial membrane potential to release cytochrome c into the cytosol and then activating caspase 3 to induce cancer cell apoptosis. NIR light triggered PDT of tumor-bearing mice with UCNPs@TiO2 as photosensitizers can suppress tumor growth efficiently due to the better tissue penetration than UV irradiation. On the basis of the evidence of in vitro and in vivo results, UCNPs@TiO2 NCs could serve as an effective photosensitizer for NIR light mediated PDT in antitumor therapy.

Abstract
To study the differentiated expression of the proto-oncogene Pokemon in nasopharyngeal carcinoma (NPC) cell lines and tissues, mRNA and protein expression levels of CNE1, CNE2, CNE3 and C666-1 were detected separately by reverse transcription polymerase chain reaction (RT-PCR), real-time PCR and Western-blotting. The immortalized nasopharyngeal epithelial cell line NP69 was used as a control. The Pokemon protein expression level in biopsy specimens from chronic rhinitis patients and undifferentiated non keratinizing NPC patients was determined by Western-blotting and arranged from high to low: C666-1>CNE1>CNE2> CNE3>NP69. The Pokemon mRNA expression level was also arranged from high to low: CNE1>CNE2>NP69>C666-1>CNE3. Pokemon expression of NP69 and C666-1 obviously varied from mRNA to protein. The Pokemon protein level of NPC biopsy specimens was obviously higher than in chronic rhinitis. The data suggest that high Pokemon protein expression is closely associated with undifferentiated non-keratinizing NPC and may provide useful information for NPC molecular target therapy.

Abstract
Cell death is a critical biological process, serving many important functions within multicellular organisms. Aberrations in cell death can contribute to the pathology of human diseases. Significant progress made in the research area enormously speeds up our understanding of the biochemical and molecular mechanisms of cell death. According to the distinct morphological and biochemical characteristics, cell death can be triggered by extrinsic or intrinsic apoptosis, regulated necrosis, autophagic cell death, and mitotic catastrophe. Nevertheless, the realization that all of these efforts seek to pursue an effective treatment and cure for the disease has spurred a significant interest in the development of promising biomarkers of cell death to early diagnose disease and accurately predict disease progression and outcome. In this review, we summarize recent knowledge about cell death, survey current and emerging biomarkers of cell death, and discuss the relationship with human diseases.
