Abstract
Many circular RNAs (circRNAs) are reported to be abnormally expressed during the progression of various tumors, and these circRNAs can be used as anti-tumor targets. Therefore, it is important to identify circRNAs that can be used effectively for the clinical diagnosis and treatment of colorectal cancer (CRC). Here, we report that hsa_Circ_0000826 (Circ_0000826), a circRNA with significantly reduced expression level in CRC tissues, is associated with a poor prognosis in patients. The silencing of Circ_0000826 promotes the proliferation of CRC cells. Conversely, the overexpression of Circ_0000826 restricted CRC cell proliferation both in vitro and in vivo. Furthermore, Circ_0000826 could target AU-rich element RNA-binding protein 1 (AUF1). AUF1, known as heterogeneous nuclear ribonucleoprotein D (hnRNP D), could bind to the c-MYC 3'-UTR and promote c-MYC expression. When Circ_0000826 binds to AUF1, it competitively inhibits the binding of AUF1 to the c-MYC 3'-UTR, which inhibits the c-MYC expression and cell proliferation. These results provide novel insights into the functional mechanism of Circ_0000826 action in CRC progression and indicate its potential use as a therapeutic target in CRC.

Adenovirus vector-mediated single chain variable fragments target the nucleocapsid protein of porcine epidemic diarrhea virus and protect against viral infection in piglets. Front Immunol 2023; 14:1058327. [PMID: 36761768 PMCID: PMC9902916 DOI: 10.3389/fimmu.2023.1058327] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Accepted: 01/04/2023] [Indexed: 01/26/2023] Open
Abstract
Porcine epidemic diarrhea virus (PEDV) mainly infects the intestinal epithelial cells of pigs, causing porcine epidemic diarrhea (PED). In particular, the virus causes severe diarrhea, dehydration, and death in neonatal piglets. Maternal immunity effectively protects neonatal piglets from PEDV infection; however, maternal antibodies can only prevent PEDV attachment and entry into target cells, but have no effects on intracellular viruses. Intracellular antibodies targeting virus-encoded proteins are effective in preventing viral infection. We previously identified four single chain variable fragments (scFvs), ZW1-16, ZW3-21, ZW1-41, and ZW4-16, which specifically targeted the PEDV N protein and significantly inhibited PEDV replication and up-regulated interferon-λ1 (IFN-λ1) expression in host cells. In our current study, the four scFvs were subcloned into replication-defective adenovirus vectors to generate recombinant adenoviruses rAdV-ZW1-16, rAdV-ZW3-21, rAdV-ZW1-41, and rAdV-ZW4-16. ScFvs were successfully expressed in Human Embryonic Kidney 293 (HEK293) cells and intestinal porcine epithelial cell line J2 (IPEC-J2) and were biosafe for piglets as indicated by body temperature and weight, scFv excretion in feces, IFN-γ and interleukin-4 (IL-4) expression in jejunum, and pathological changes in porcine tissue after oral administration. Western blotting, immunofluorescence, and immunohistochemical analyses showed that scFvs were expressed in porcine jejunum. The prophylactic effects of rAdV-ZW, a cocktail of the four rAdV-scFvs, on piglet diarrhea caused by PEDV was investigated. Clinical symptoms in piglets orally challenged with PEDV, following a two-time treatment with rAdV-ZW, were significantly reduced when compared with PEDV-infected piglets treated with phosphate buffered saline (PBS) or rAdV-wild-type. Also, no death and jejunal lesions were observed. ScFv co-localization with the PEDV N protein in vivo was also observed. Next, the expression of pro-inflammatory serum cytokines such as tumor necrosis factor-α (TNF-α), IL-6, IL-8, IL-12, and IFN-λ was assessed by enzyme-linked immunosorbent assay (ELISA), which showed that scFvs significantly suppressed PEDV-induced pro-inflammatory cytokine expression and restored PEDV-inhibited IFN-λ expression. Therefore, our study supported a promising role for intracellular scFvs targeting the PEDV N protein to prevent and treat diarrhea in PEDV-infected piglets.

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:6890790. [PMID: 36285283 PMCID: PMC9588377 DOI: 10.1155/2022/6890790] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 09/04/2022] [Accepted: 10/03/2022] [Indexed: 11/17/2022]
Abstract
Endometriosis (EMs) is a benign disease with the characteristics of invasion and migration, and its pathogenesis is related to hypoxia. The abnormal activation of glioma-associated oncogene homolog 1 (GLI1) plays an important role in the metastasis of multiple types of tumors. However, it is not clear whether GLI1 regulates the migration and invasion of endometrial stromal cells under hypoxic condition. Therefore, we use comprehensive analysis to explore the effects of hypoxic on GLI1 expression and their regulation on the pathogenesis of EMs. In this study, from immunohistochemistry, RT-qPCR, and western blot analysis, we discovered that the expression of hypoxia-induced factor-1α (HIF-1α) and GLI1 was significantly increased in eutopic and ectopic endometrium of patients with EMs. In human primary eutopic endometrial stromal cells (ESCs), hypoxia can increase the expression of HIF-1α and GLI1 in a time-dependent manner. And hypoxia could promote GLI1 expression in a HIF-1α-dependent manner. Moreover, data from transwell assays manifested that the migration and invasion ability of ESCs was significantly enhanced under hypoxia, and this effect could be reversed by silencing GLI1. Furthermore, the expression of MMP2 and MMP9 was also increased under hypoxia, while silencing GLI1 could reverse this event. In summary, our research verified that GLI1, which activated by hypoxia, may contribute to the migration and invasion of ESCs through the upregulation of MMP2 and MMP9 and can be a novel therapeutic target in EMs.

Abstract
Leukemia stem cells (LSCs) are responsible for leukemia initiation and targeting LSCs is one strategy to treat this disease. This study aims to target LSCs using multi-siRNA loaded antibodies modified with mesoporous silica nanoparticles (MSNs). Here, both siRNAGLI1 and siRNASMO were loaded in an anti-CD34 antibody modified with MSNs, and then, the MSN@siRNAGLI1@Antibody + MSNs@siRNASMO@Antibody cocktail was used to target LSCs. Expression levels of BCL-2 in LSCs were significantly reduced whereas Bax expression was significantly increased after treatment with nano-drug carriers. In addition, these nano-drug carriers also effectively induced the apoptosis of LSCs. The MSNs@siRNAGLI1@Antibody + MSNs@siRNASMO@Antibody cocktail significantly inhibited LSCs. In short, we constructed two target MSN nano-drug carriers where loaded siRNAs can be used in a chemotherapeutic drug cocktail to improve the treatment of leukemia.

Abstract
BACKGROUND Rosmarinic acid (RA) has been shown to exert anti-tumor effects on various types of cancer. However, its roles in the treatment of pancreatic ductal adenocarcinoma (PDAC) and the underlying mechanisms remain elusive. PURPOSE The present study aimed to investigate the therapeutic effects of RA on PDAC as well as the underlying mechanisms. STUDY DESIGN Evaluation of the effects of RA on PDAC malignancy both in vitro and in vivo. METHODS Cell counting kit 8 (CCK8) assay, colony formation assay, 5-Ethynyl-2'-deoxyuridine (EDU) incorporation assay, cell cycle analysis, and apoptosis assay were conducted to assess the inhibitory effect of RA on PDAC cell proliferation. Meanwhile, western blotting and RT-qPCR assay were performed to detect the target gene expression at protein and mRNA levels, respectively. Moreover, the in vivo anti-tumor activities of RA were assayed in an xenograft mouse model of PDAC. RESULTS RA dramatically down-regulated Gli1 and its downstream targets. Further studies showed that RA prevents the nuclear translocation of Gli1, while promoting the degradation of cytosolic Gli1 via the proteasome pathway. Moreover, we observed that RA induced G1/S cell cycle arrest and apoptosis in the PDAC cells through regulating the expression of P21, P27, CDK2, Cyclin E, Bax, and Bcl-2, it inhibited the PDAC cell migration and invasion via E-cadherin and MMP-9. Notably, Gli1 overexpression markedly reversed the above RA-induced effects on PDAC cells, whereas Gli1 knockdown enhanced the effects. Additionally, the in vivo assays demonstrated that RA suppresses the tumor growth of PDAC presumably by inhibiting Gli1. CONCLUSION We provided evidence that RA restrained the nuclear translocation of Gli1 and facilitates Gli1 degradation via proteasome pathway, reducing the malignancy of PDAC cells. These findings implicated RA as a therapeutic agent for PDAC.

Abstract
Pancreatic cancer (PC) is one of the leading causes of death and is the fourth most malignant tumor in men. The epigenetic and genetic alterations appear to be responsible for development of PC. Small interfering RNA (siRNA) is a powerful genetic tool that can bind to its target and reduce expression level of a specific gene. The various critical genes involved in PC progression can be effectively targeted using diverse siRNAs. Moreover, siRNAs can enhance efficacy of chemotherapy and radiotherapy in inhibiting PC progression. However, siRNAs suffer from different off target effects and their degradation by enzymes in serum can diminish their potential in gene silencing. Loading siRNAs on nanoparticles can effectively protect them against degradation and can inhibit off target actions by facilitating targeted delivery. This can lead to enhanced efficacy of siRNAs in PC therapy. Moreover, different kinds of nanoparticles such as polymeric nanoparticles, lipid nanoparticles and metal nanostructures have been applied for optimal delivery of siRNAs that are discussed in this article. This review also reveals that how naked siRNAs and their delivery systems can be exploited in treatment of PC and as siRNAs are currently being applied in clinical trials, significant progress can be made by translating the current findings into the clinical settings.

GLI1/GLI2 functional interplay is required to control Hedgehog/GLI targets gene expression. Biochem J 2021; 477:3131-3145.

Abstract
The Hedgehog-regulated transcription factors GLI1 and GLI2 play overlapping roles in development and disease; however, the mechanisms underlying their interplay remain elusive. We report for the first time that GLI1 and GLI2 physically and functionally interact in cancer cells. GLI1 and GLI2 were shown to co-immunoprecipitate in PANC1 pancreatic cancer cells and RMS13 rhabdomyosarcoma cells. Mapping analysis demonstrated that the zinc finger domains of both proteins are required for their heteromerization. RNAi knockdown of either GLI1 or GLI2 inhibited expression of many well-characterized GLI target genes (BCL2, MYCN, PTCH2, IL7 and CCND1) in PANC1 cells, whereas PTCH1 expression was only inhibited by GLI1 depletion. qPCR screening of a large set of putative canonical and non-canonical Hedgehog/GLI targets identified further genes (e.g. E2F1, BMP1, CDK2) strongly down-regulated by GLI1 and/or GLI2 depletion in PANC1 cells, and demonstrated that ANO1, AQP1 and SOCS1 are up-regulated by knockdown of either GLI1 or GLI2. Chromatin immunoprecipitation showed that GLI1 and GLI2 occupied the same regions at the BCL2, MYCN and CCND1 promoters. Furthermore, depletion of GLI1 inhibited GLI2 occupancy at these promoters, suggesting that GLI1/GLI2 interaction is required for the recruitment of GLI2 to these sites. Together, these findings indicate that GLI1 and GLI2 co-ordinately regulate the transcription of some genes, and provide mechanistic insight into the roles of GLI proteins in carcinogenesis.

Abstract
Unruptured ectopic pregnancy (UEP) is a common cause of morbidity and, occasionally, of mortality in women of reproductive age. Pharmacological intervention is a common therapeutic approach for early-stage UEP. Herein, we investigated the cytotoxic effect and novel mechanism of shikonin, a natural naphthoquinone pigment purified from Lithospermum erythrorhizon, in human trophoblast cells. These data demonstrated that shikonin suppressed proliferation and induced apoptosis in a time-dependent manner in HTR-8/SVneo cells. Shikonin blocked autophagic flux and promoted p62 interaction with caspase 8, resulting in caspase 8 activation. Moreover, shikonin suppressed GLI1 expression, and GLI1 overexpression attenuated shikonin-induced cell apoptosis. Although silencing GLI1 slightly promoted cell apoptosis, p62 overexpression enhanced GLI1 silencing-induced cell apoptosis by activating caspase 8. Furthermore, rapamycin increased shikonin-induced cell apoptosis in HTR-8/SVneo cells, whereas 3-MA attenuated the cytotoxic effect of shikonin. In conclusion, shikonin suppressed trophoblast cell growth by silencing GLI1 and increasing p62 co-mediated activation of caspase 8, which suggested a potential novel therapeutic target for UEP.

Abstract
Background Glioma-associated oncogene homolog 1 (Gli1), affects the progression and the stemness characteristics of malignant carcinoma. The aim of the present study was to identify the relation between Glioma-associated oncogene homolog 1 (Gli1) and stemness and determine its clinical significance in gastric adenocarcinoma (GA). We investigated Gli1 expression and its correlation with other stemness-associated proteins in 169 GA samples and 5 GA cell lines. Methods To elucidate the role of Gli1 in the clinicopathological significance and stemness of GA, tissues samples from 169 GA patients were collected for immunohistochemistry (IHC). Additionally, MKN74, MKN28, NCI-N87, SNU638, AGS cells were collected for western blotting, MKN28 cells were collected for spheroid formation assay. Results Results showed that Gli1 expression was closely related to tumor grade, primary tumor (pT) stage, distant metastasis, clinical stage, gross type, microvessel density, and shorter overall survival (OS). Cox regression analysis verified that Gli1 was an independent prognostic factor for OS. Furthermore, Gli1 expression correlated with the expression of stemness-related genes, CD44, LSD1, and Sox9. Gli1 inhibitor GANT61 significantly decreased the expression of CD44 and LSD1, and spheroid formation ability of the MKN28 cells. Conclusions In conclusion, Gli1 may be a poor prognostic indicator and a potential cancer stemness-related protein in GA.

Abstract
OBJECTIVE Resistance to radiotherapy accounts for most treatment failures in cervical cancer patients who receive radical radiation therapy. To discover the possible mechanism of radioresistance and improve the 5-year survival rate, we focused on how sex-determining region Y-box 2 (SOX2) mediates radioresistance in cervical cancer as well as on the interaction between SOX2 and the hedgehog (Hh) signaling pathway in this study. METHODS We established the acquired radioresistant subclone cells Hela-RR and Siha-RR. RT-qPCR, Western blot analysis, IHC, clonogenic survival assay, CCK-8 assay, apoptosis analysis, cell cycle analysis and xenograft models were used to explore the relationship between SOX2 expression and radiation resistance and to determine how SOX2 mediates radioresistance in cervical cancer. Furthermore, luciferase reporter and ChIP-PCR assays were utilized to assess the interaction between SOX2 and the Hh signaling pathway. RESULTS Our research suggested that high expression of SOX2 was responsible for radioresistance in cervical cancer. SOX2 was observed to be closely related to irradiation-induced survival, proliferation, apoptosis, and cell cycle changes. The Hh signaling pathway was found to be activated in Hela-RR and Siha-RR, and the activation changed with SOX2 expression. IHC staining of SOX2 and Gli1 showed a close relationship between SOX2 and the Hh pathway. Luciferase reporter and ChIP-PCR assays demonstrated that SOX2 interacted with the Hh signaling pathway by occupying the HHAT promoter. CONCLUSIONS SOX2 is a potential therapeutic target of irradiation resistance in cervical cancer. It mediates radioresistance in cervical cancer via the Hh signaling pathway.

Abstract
Few studies have evaluated Hedgehog (Hh) signaling pathway activation in different types of ovarian tumors including benign, borderline and malignant ovarian tumors. The present study investigated the expression of Hh signaling pathway components (SHH, SMO, PTCH, and GLI1) in 193 ovarian epithelial tumor specimens (including 147 malignant epithelial ovarian cancers, 30 borderline ovarian tumors, 16 benign ovarian epithelial tumors) and 11 normal ovarian epithelial tissues by immunohistochemistry. The results demonstrated widespread expression of Hh pathway molecules in ovarian tumors. However, there was no significant difference in the expression intensity of SHH among the four groups (P>0.05). Statistically significant differences were identified in the expression intensity of the SMO, PICH and GLI1 among groups (P<0.001). In addition, significant differences were also revealed in the expression levels of SMO (P=0.013) and GLI1 (P=0.0005) between the platinum drug-sensitive and drug-resistant groups. The overexpression of SMO and GLI1 was further confirmed in the cisplatin-resistant ovarian cancer cell line A2780/DDP by immunofluorescence, flow cytometry and western blotting. The results revealed that the Hh pathway components SMO, PICH and GLI1 are activated in ovarian epithelial tumors. Novel potential associations between cisplatin resistance and the overexpression of SMO and Gli1 in malignant epithelial ovarian cancer were also observed, which may provide an innovative approach to the treatment of drug resistant ovarian epithelial cancer.

Abstract
Ras mutations and overexpression of the Ras protein, p21Ras, are main causes of cancer development and progression, which has made the Ras gene and p21Ras important targets for therapy of Ras-driven cancers. We previously prepared recombinant adenovirus KGHV100 based on replication-defective adenovirus type 5, which could intracellularly express anti-p21Ras single chain fragment viable antibodies (scFv) and repress tumor growth in vitro and in vivo. However, the anti-tumor effects of this anti-p21Ras scFv were limited by short-term scFv expression due to a replication defect of KGHV100. To enhance the anti-tumor efficacy and safety of anti-p21Ras scFv, the present study constructed a dual-promoter-regulated recombinant adenovirus KGHV300 that carried anti-p21Ras scFv. In KGHV300, the expression levels of the essential replication genes E1a and E1b, were controlled by the human telomerase reverse transcriptase promoter and the hypoxia response element, respectively, and the anti-p21Ras scFv gene was controlled by the cytomegalovirus promoter. The conditional replication of KGHV300 and its antitumor efficacy were characterized in several tumor cell lines in vitro and in xenograft models of human breast cancer in nude mice. TCID50 assay demonstrated that KGHV300 could replicate in tumor cell lines but not in normal cell lines. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay indicated that the growth of tumor cells was effectively inhibited by KGHV300 infection. In MDA-MB-231 tumor xenograft models, KGHV300 effectively and significantly inhibited tumor growth and induced apoptosis of tumor cells. We concluded that the recombinant adenovirus KGHV300 may be a more potent and safer antitumor therapeutic for Ras-driven cancer biotherapy.

Proteasome activator subunit 3 promotes pancreatic cancer growth via c-Myc-glycolysis signaling axis. Cancer Lett 2016; 386:161-167.

Abstract
Pancreatic cancer has the worst prognosis among all cancers and novel markers and therapeutic targets are desperately needed for this terribly deadly disease. Proteasome activator subunit 3 (PSME3) is highly involved in the initiation and progression of many human cancers. However, the potential effect of PSME3 on pancreatic cancer remains largely unknown. In the present study, we first found that PSME3 was significantly upregulated in pancreatic cancer cells and tissues at both mRNA and protein levels using qRT-PCR, western blot analysis, Oncomine data mining and immunohistochemical analysis. High PSME3 expression was positively correlated with tumor size and pM stage, and was significantly correlated with poor prognosis in pancreatic cancer patients revealed by Kaplan-Meier analysis. Gene set enrichment analysis demonstrated that the gene sets related to cell proliferation and metastasis were positively correlated with elevated PSME3 expression. Consistently, silencing of PSME3 suppressed cell proliferation and invasive capacity of pancreatic cancer. Mechanistically, PSME3 inhibited the degradation of c-Myc and thus enhanced glycolysis, which ultimately led to the oncogenic effects of PSME3 on pancreatic cancer. Collectively, our data suggest that PSME3 plays oncogenic roles in pancreatic cancer by inhibiting c-Myc degradation to promote glycolysis, and could serve as a novel therapeutic target for pancreatic cancer treatment.

Abstract
Pancreatic cancer is aggressive and therefore difficult to treat; however, continued efforts have been made with the aim of developing an effective therapy against the disease. The Hedgehog (Hh) signaling pathway is reportedly involved in the proliferation and survival of pancreatic cancer cells. The transcription factor glioma-associated oncogene (Gli) is a key component of the Hh signaling pathway and the primary effector of pancreatic cancer development. Inhibiting Gli is a proven therapeutic strategy for this disease. The present study examined the regulation of Gli and the expression of its target genes to identify an inhibitor of the Sonic Hh (Shh) pathway. A germacranolide sesquiterpene lactone (GSL) was isolated from Siegesbeckia glabrescens as an inhibitor of Gli-mediated transcription. The results demonstrated that GSL inhibited Shh-induced osteoblast differentiation and Gli homolog 1 (Gli1)-mediated transcriptional activity in mesenchymal C3H10T1/2 stem cells. Furthermore, GSL suppressed Gli-mediated transcriptional activity in human pancreatic cancer PANC-1 and AsPC-1 cells, which resulted in reduced cancer cell proliferation and downregulated expression of the Gli-target genes, Gli1 and cyclin D1. A sesquiterpene lactone from S. glabrescens may therefore serve as a candidate for the treatment of Hh/Gli-dependent pancreatic cancer.

Abstract
AIM: To construct a recombinant lentiviral vector carrying siRNA targeting the SMO gene, and to confirm its inhibitory effect on SMO gene expression in pancreatic cancer cells.
METHODS: Three SMO gene-targeted siRNA fragments were designed and synthesized, and recombinant DNA technology was used to introduce these three fragments into a lentiviral expression vector. After determination of the virus titer, the constructed lentiviral vector was tranfected into human pancreatic cancer cell line SW1990. RT-PCR was used to detect the expression of SMO gene and identify the best interference expression vector. SMO protein expression was detected by Western blot.
RESULTS: Gene sequencing and restriction endonuclease digestion results suggested successful synthesis of SMO-targeted siRNA fragments and correct insertion into the lentiviral vector. The virus titers were 5.31 × 108 TU/mL, 1.49 × 109 TU/mL and 8.50 × 108 TU/mL, respectively. After transfecting SW1990 cells, the SMO gene expression inhibition rates were 86.00%, 74.85% and 19.22%, respectively. The best interference expression vector can achieve an SMO protein inhibition rate > 80% in SW1990 cells.
CONCLUSION: We have successfully constructed an SMO gene-targeted siRNA lentiviral vector, and the vector can effectively inhibit the expression of SMO gene in pancreatic cancer cells, thus providing a good experimental tool for further research.

Abstract
The abnormally activated hedgehog (Hh) signaling pathway is involved in the regulation of proliferation and apoptosis in pancreatic cancer cells, while its exact molecular mechanism is not clear. The purpose of this study was to investigate the regulatory effect of Hh signaling pathway on the transcription of BIRC3 gene and its underlying mechanism in pancreatic cancer cells, as well as the relationship between the Gli1-dependent BIRC3 transcription and cell survival. Firstly, we examined the effect of knockdown or overexpression of Hh on BIRC3 messenger RNA (mRNA) expression by real-time RT-PCR. Then, the regulatory mechanism of Gli1 to BIRC3 gene transcription was investigated by XChIP-PCR and luciferase assays. Finally, the cell survival mediated by the Gli1-dependent BIRC3 transcription was studied by MTT and annexin V-FITC/propidiumiodide (PI) assays. We found that the expression level of BIRC3 mRNA was positively correlated to SHh/Gli1 signaling activation in three pancreatic cancer cell lines. The XChIP-PCR and luciferase assays data showed that the transcription factor Gli1 bound to some enhancers within the promoter regions of BIRC3 gene and promoted gene transcription. The cell proliferation was increased significantly by SHh/Gli1 expression while the apoptotic rate was reduced under the same condition. Moreover, BIRC3 knockdown inhibited cell proliferation and survival induced by SHh overexpression. Our study reveals that Gli1 promoted transcription of BIRC3 gene via cis-acting elements and the SHh-Gli1 signaling pathway maintained cell survival partially through this Gli1-dependent BIRC3 model in pancreatic cancer cells.

Abstract
The aim of this study is to evaluate chemopreventive and therapeutic efficacy of tea polyphenols epigallocatechin gallete (EGCG) and theaflavin (TF) on self-renewal Wnt and Hedgehog (Hh) pathways during CCl4/N-nitosodiethylamine-induced mouse liver carcinogenesis. For this purpose, the effect of EGCG/TF was investigated in liver lesions of different groups at pre-, continuous and post initiation stages of carcinogenesis. Comparatively increased body weights were evident due to EGCG/TF treatment than carcinogen control mice. Both EGCG and TF could restrict the development of hepatocellular carcinoma at 30th week of carcinogen application showing potential chemoprevention in continuous treated group (mild dysplasia) followed by pretreated (moderate dysplasia) and therapeutic efficacy in posttreated group (mild dysplasia). This restriction was associated with significantly reduced proliferation, increased apoptosis, decreased prevalence of hepatocyte progenitor cell (AFP) and stem cell population (CD44) irrespective of EGCG/TF treatments. The EGCG/TF could modulate the Wnt pathway by reducing β-catenin and phospho-β-catenin-Y-654 expressions along with up-regulation of sFRP1 (secreted frizzled-related protein 1) and adenomatosis polyposis coli during the restriction. In case of the Hh pathway, EGCG/TF could also reduce expressions of glioma-associated oncogene homolog 1 (Gli1) and SMO (smoothened homolog) along with up-regulation of PTCH1 (patched homolog 1). As a result, in Wnt/Hh regulatory pathways decreased expressions of β-catenin/Gli1 target genes like CyclinD1, cMyc and EGFR/phospho-EGFR-Y-1173 and up-regulation of E-cadherin were seen during the restriction. Thus, the restriction of liver carcinogenesis by EGCG/TF was due to reduction in hepatocyte progenitor cell/stem cell population along with modulation of Wnt/Hh and other regulatory pathways.

Abstract
Pancreatic cancer (PCa), which is now the fourth most frequent cause of cancer-related death, has a median survival of less than 6 months and a 5-year survival rate of <6%. The hallmarks of this cancer include poor outcome, short survival duration, and resistance to therapy. The poor prognosis of PCa is related to its local recurrence, lymph node and liver metastases, and peritoneal dissemination. Recent studies have indicated that resveratrol has cancer-chemopreventive and anticancer activities. In this short review we summarize the chemopreventive and treatment effects of resveratrol in PCa, as follows: resveratrol inhibits the proliferation of pancreatic cancer cells; induces apoptosis and cell cycle arrest; inhibits metastasis and invasion of PCa cells; inhibits the proliferation and viability of PCa stem cells; enhances the chemoradiosensitization of PCa cells; and can affect diabetes mellitus in addition to PCa. On the basis of these data, resveratrol may be considered a potential anticancer agent for the treatment of PCa.

Abstract
The Hedgehog pathway is a pivotal morphogenic driver during embryonic development and a key regulator of adult stem cell self-renewal. The discovery of resident multipotent vascular stem cells and adventitial progenitors within the vessel wall has transformed our understanding of the origin of medial and neointimal vascular smooth muscle cells (SMCs) during vessel repair in response to injury, lesion formation, and overall disease progression. This review highlights the importance of components of the Hh and Notch signalling pathways within the medial and adventitial regions of adult vessels, their recapitulation following vascular injury and disease progression, and their putative role in the maintenance and differentiation of resident vascular stem cells to vascular lineages from discrete niches within the vessel wall.

Abstract
Breast cancer is the most frequently diagnosed malignancy in American women. While significant progress has been made in the development of modern diagnostic tools and surgical treatments, only marginal improvements have been achieved with relapsed metastatic breast cancer. Small interfering RNAs (siRNAs) mediate gene silencing of a target protein by disrupting messenger RNAs in an efficient and sequence-specific manner. One application of this technology is the knockdown of genes responsible for tumorigenesis, including those driving oncogenesis, survival, proliferation and death of cells, angiogenesis, invasion and metastasis, and resistance to treatment. Non-viral nanocarriers have attracted attention based on their potential for targeted delivery of siRNA and efficient gene silencing without toxicity. Here, we review promising, non-viral delivery strategies employing liposomes, nanoparticles and inorganic materials in breast cancer.

Abstract
INTRODUCTION Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer death in the USA. The 5-year survival of < 5% has not changed in decades. In contrast to other major cancers, the incidence of PDAC is increasing. AREAS COVERED The aims of this paper are first to analyze why PDAC is so difficult to treat and, second, to suggest future directions for PDAC therapeutics. The authors provide an article that is based on a comprehensive search through MEDLINE and the clinicalTrials.gov website. EXPERT OPINION Progress has been made recently. Notably, FOLFIRINOX or nab-paclitaxel plus gemcitabine provide survival benefit over gemcitabine alone, which was previously the mainstay of therapy for PDAC. Most of the current trials are testing combinations of repurposed drugs rather than addressing key targets in the PDAC pathogenesis. It is clear that to really make an impact on this disease, it will be necessary to address three different problems with targeted therapeutics. First, it is important to eradicate PDAC stem cells that result in recurrence. Second, it is important to reduce the peritumoral stroma that provides the tumors with growth support and provides a barrier to access of therapeutic agents. Finally, it is important to address the marked cachexia and metabolic derangement that contribute to morbidity and mortality and further complicate therapeutic intervention.

Abstract
Increasing evidence has demonstrated that ezrin-radixin-moesin (ERM)-binding phosphoprotein 50 (EBP50) is involved in the malignant transformation of numerous human cancers. The present study investigated the involvement of EBP50 overexpression in the tumorigenicity of pancreatic cancer (PC). The results revealed that overexpression of EBP50 suppressed cell growth, promoted cell apoptosis and arrested G1-to-S phase progression in two human PC cell lines. Overexpression of EBP50 also suppressed B-cell lymphoma 2 (Bcl-2) expression. Furthermore, nude mouse tumor xenograft models were established by the subcutaneous injection of cell lines stably transfected with an EBP50-expressing plasmid. The in vivo data indicated that overexpression of EBP50 inhibited the growth of the PC tumors and induced cell apoptosis. Thus, the present study demonstrated that EBP50 overexpression induces growth inhibition and apoptosis in PC by decreasing Bcl-2 expression. The results suggest that EBP50 may function as a potential tumor suppressor in vivo and in vitro.

The transcription factor GLI1 interacts with SMAD proteins to modulate transforming growth factor β-induced gene expression in a p300/CREB-binding protein-associated factor (PCAF)-dependent manner. J Biol Chem 2014; 289:15495-506.

Abstract
The biological role of the transcription factor GLI1 in the regulation of tumor growth is well established; however, the molecular events modulating this phenomenon remain elusive. Here, we demonstrate a novel mechanism underlying the role of GLI1 as an effector of TGFβ signaling in the regulation of gene expression in cancer cells. TGFβ stimulates GLI1 activity in cancer cells and requires its transcriptional activity to induce BCL2 expression. Analysis of the mechanism regulating this interplay identified a new transcriptional complex including GLI1 and the TGFβ-regulated transcription factor, SMAD4. We demonstrate that SMAD4 physically interacts with GLI1 for concerted regulation of gene expression and cellular survival. Activation of the TGFβ pathway induces GLI1-SMAD4 complex binding to the BCL2 promoter whereas disruption of the complex through SMAD4 RNAi depletion impairs GLI1-mediated transcription of BCL2 and cellular survival. Further characterization demonstrated that SMAD2 and the histone acetyltransferase, PCAF, participate in this regulatory mechanism. Both proteins bind to the BCL2 promoter and are required for TGFβ- and GLI1-stimulated gene expression. Moreover, SMAD2/4 RNAi experiments showed that these factors are required for the recruitment of GLI1 to the BCL2 promoter. Finally, we determined whether this novel GLI1 transcriptional pathway could regulate other TGFβ targets. We found that two additional TGFβ-stimulated genes, INTERLEUKIN-7 and CYCLIN D1, are dependent upon the intact GLI1-SMAD-PCAF complex for transcriptional activation. Collectively, these results define a novel epigenetic mechanism that uses the transcription factor GLI1 and its associated complex as a central effector to regulate gene expression in cancer cells.

Abstract
The development of targeted agents and chemotherapies for pancreatic cancer has only modestly affected clinical outcome and not changed 5-year survival. Fortunately the genetic and molecular mechanisms underlying pancreatic cancer are being rapidly uncovered and are providing opportunities for novel targeted therapies. Oncolytic viral therapy is one of the most promising targeted agents for pancreatic cancer. This review will look at the current state of the development of these self-replicating nanoparticles in the treatment of pancreatic cancer.

Abstract
2-Amino-2-[2-(4-octylphenyl)]-1,3-propanediol hydrochloride (FTY720) is a potent immunosuppressant which has been approved by the Food and Drug Administration (FDA) as a new treatment for multiple sclerosis. As an immunosuppressant, it displays its anti-multiple sclerosis, immunosuppressive effects by activating sphingosine-1-phosphate receptors (S1PRs). In addition to the immunosuppressive effects, FTY720 also shows preclinical antitumor efficacy in several cancer models. In most cases, phosphorylation of FTY720 is not required for its cytotoxic effect, indicating the involvement of S1PR-independent mechanisms which are starkly different from the immunosuppressive property of FTY720. In the present study, we reviewed the rapidly advancing field of FTY720 in cancer therapy as well as some molecular targets of the unphosphorylated form of FTY720.
