Abstract
Ovarian cancer is a prominent cancer worldwide with a relatively low survival rate for women diagnosed. Many individuals are diagnosed in the late stage of the disease and are prescribed a wide variety of treatment options. Current treatment options are primarily a combination of surgery and chemotherapy as well as a new but promising treatment involving immunotherapy. Nevertheless, contemporary therapeutic modalities exhibit a discernible lag in advancement when compared with the strides achieved in recent years in the context of other malignancies. Moreover, many surgery and chemotherapy options have a high risk for recurrence due to the late-stage diagnosis. Therefore, there is a necessity to further treatment options. There have been many new advancements in the field of immunotherapy. Immunotherapy has been approved for 16 various types of cancers and has shown significant treatment potential in many other cancers as well. Researchers have also found many promising outlooks for immunotherapy as a treatment for ovarian cancer. This review summarizes many of the new advancements in immunotherapy treatment options and could potentially offer valuable insights to gynecologists aimed at enhancing the efficacy of their treatment approaches for patients diagnosed with ovarian cancer.

Li CM, Chen Z. Autoimmunity as an Etiological Factor of Cancer: The Transformative Potential of Chronic Type 2 Inflammation. Front Cell Dev Biol 2021; 9:664305.

Abstract
Recent epidemiological studies have found an alarming trend of increased cancer incidence in adults younger than 50 years of age and projected a substantial rise in cancer incidence over the next 10 years in this age group. This trend was exemplified in the incidence of non-cardia gastric cancer and its disproportionate impact on non-Hispanic white females under the age of 50. The trend is concurrent with the increasing incidence of autoimmune diseases in industrialized countries, suggesting a causal link between the two. While autoimmunity has been suspected to be a risk factor for some cancers, the exact mechanisms underlying the connection between autoimmunity and cancer remain unclear and are often controversial. The link has been attributed to several mediators such as immune suppression, infection, diet, environment, or, perhaps most plausibly, chronic inflammation because of its well-recognized role in tumorigenesis. In that regard, autoimmune conditions are common causes of chronic inflammation and may trigger repetitive cycles of antigen-specific cell damage, tissue regeneration, and wound healing. Illustrating the connection between autoimmune diseases and cancer are patients who have an increased risk of cancer development associated with genetically predisposed insufficiency of cytotoxic T lymphocyte-associated protein 4 (CTLA4), a prototypical immune checkpoint against autoimmunity and one of the main targets of cancer immune therapy. The tumorigenic process triggered by CTLA4 insufficiency has been shown in a mouse model to be dependent on the type 2 cytokines interleukin-4 (IL4) and interleukin-13 (IL13). In this type 2 inflammatory milieu, crosstalk with type 2 immune cells may initiate epigenetic reprogramming of epithelial cells, leading to a metaplastic differentiation and eventually malignant transformation even in the absence of classical oncogenic mutations. Those findings complement a large body of evidence for type 1, type 3, or other inflammatory mediators in inflammatory tumorigenesis. This review addresses the potential of autoimmunity as a causal factor for tumorigenesis, the underlying inflammatory mechanisms that may vary depending on host-environment variations, and implications to cancer prevention and immunotherapy.

Abstract
IL-4 production is associated with low-avidity, poorly cytotoxic T cell induction that contributes to viral immune evasion and the failure of T cell-based vaccines. Yet, the precise mechanisms that regulate IL-4 signalling in T cells remain elusive. Mounting evidence indicates that cells can dynamically alter their IL-4/IL-13 receptor signature to modulate downstream immune outcomes upon pathogen encounter. Here, we describe how naïve (CD62L+CD44lo-mid) CD4 and CD8 T cells distinctly engage both STAT6 and STAT3 in response to IL-4. We further show that IL-4R⍺ expression is both time- and IL-4 concentration-dependent. Remarkably, our findings reveal that STAT3 inhibition can ablate IL-4R⍺ and affect transcriptional expression of other Stat and Jak family members. By extension, the loss of STAT3 lead to aberrant STAT6 phosphorylation, revealing an inter-regulatory relationship between the two transcription factors. Moreover, IL-4 stimulation down-regulated TGF-β1 and IFN-γR1 expression on naïve T cells, possibly signifying the broad regulatory implications of IL-4 in conditioning lineage commitment decisions during early infection. Surprisingly, naïve T cells were unresponsive to IL-13 stimulation, unlike dendritic cells. Collectively, these findings could be exploited to inform more efficacious vaccines, as well as design treatments against IL-4/IL-13-associated disease conditions.

Abstract
OBJECTIVE To identify novel immunologic targets and biomarkers associated with overall survival (OS) in high-grade serous ovarian cancer (HGSC). METHODS In this retrospective study, microarray data from 51 HGSC specimens were analyzed (Affymetrix HG-U133A). A panel of 183 immune/inflammatory response related genes linked to 279 probe sets was constructed a priori and screened. Associations between gene expression and OS were assessed using logrank tests. Multiple testing was addressed within the False Discovery Rate (FDR) framework. For external validation, TCGA Ovarian dataset and five GSE publicly available HGSC datasets were evaluated. RESULTS In Duke data, 110 probe sets linked to 83 immunologic/inflammatory-related genes were differentially expressed in tumors from long versus short-term HGSC survivors (adjusted p < 0.05). In TCGA, concordant with the results from the Duke discovery cohort, high expression of one probe (IL6R) demonstrated a consistent significance and concordant association with higher expression in long-term HGSC survivors (Duke q-value = 0.022) and improved OS in the TCGA dataset (p-value = 0.015, HR = 0.8). Thirteen genes in GSE14764 (N = 4) and GSE26712 (N = 9) datasets had significant p-values and consistent concordant with Duke Data. Despite the significant associations of gene expression and OS in the individual GSE datasets, in the GSE meta-analysis no genes were consistently concordant and significantly associated with survival. CONCLUSIONS Evaluation of IL6R expression may be warranted based on higher expression in long-term survivors and association with improved survival in advanced HGSC. The other candidate genes may also be of worthy of further exploration to enhance immuno-oncology drug discovery.

Combination immunotherapy with IL-4 Pseudomonas exotoxin and IFN-α and IFN-γ mediate antitumor effects in vitro and in a mouse model of human ovarian cancer. Immunotherapy 2019; 11:483-496.

Abstract
AIM We have shown that IL-4 fused to Pseudomonas exotoxin (IL-4-PE) is cytotoxic to ovarian cancer cell lines. The antineoplastic properties of IFN-α, IFN-γ and IL-4-PE have been studied and showed some promise in the clinical trials. Here, we investigated whether the combination of IL-4-PE, IFN-α and IFN-γ will result in increased ovarian cancer cell death in vitro and in vivo. MATERIALS & METHODS Ovarian cancer cells were tested in vitro to analyze the cytotoxic effects of IL-4-PE, IFN-α and IFN-γ, and the combination of all three. Tumor-bearing xenograft mice were treated with the combination of IL-4-PE, IFN-α and IFN-γ to monitor their overall survival. The JAK/STAT phosphorylation signaling pathways were studied to delineate the mechanism of synergistic antitumor activity. RESULTS The combination of IL-4-PE with IFN-α and IFN-γ resulted in increased ovarian cancer cell death in vitro and in vivo. Mechanistically, the synergistic antitumor effect was dependent on interferon signaling, but not IL-4-PE signaling as determined by signaling specific chemical inhibitors. The combination therapy induced the activation of critical mediators of apoptosis. CONCLUSION The combination of IL-4-PE with interferons increased overall survival of mice with human ovarian cancer xenograft. These data suggest that this novel combination could provide a unique approach to treating ovarian cancer.

Abstract
Receptor-mediated drug delivery presents an opportunity to enhance therapeutic efficiency by accumulating drug within the tissue of interest and reducing undesired, off-target effects. In cancer, receptor overexpression is a platform for binding and inhibiting pathways that shape biodistribution, toxicity, cell binding and uptake, and therapeutic function. This review will identify tumor-targeted drug delivery vehicles and receptors that show promise for clinical translation based on quantitative in vitro and in vivo data. The authors describe the rationale to engineer a targeted drug delivery vehicle based on the ligand, chemical conjugation method, and type of drug delivery vehicle. Recent advances in multivalent targeting and ligand organization on tumor accumulation are discussed. Revolutionizing receptor-mediated drug delivery may be leveraged in the therapeutic delivery of chemotherapy, gene editing tools, and epigenetic drugs.

Abstract
Cytokines of the common gamma-chain receptor family, comprising interleukin (IL)-2, IL-4, IL-7, IL-9, IL-15 and IL-21, are vital with respect to organizing and sustaining healthy immune cell functions. Supporting the anti-cancer immune response, these cytokines inspire great interest for their use as vaccine adjuvants and cancer immunotherapies. It is against this background that gamma delta (γδ) T cells, as special-force soldiers and natural contributors of the tumor immunosurveillance, also received a lot of attention the last decade. As γδ T cell-based cancer trials are coming of age, this present review focusses on the effects of the different cytokines of the common gamma-chain receptor family on γδ T cells with respect to boosting γδ T cells as a therapeutic target in cancer immunotherapy. This review also gathers data that IL-15 in particular exhibits key features for augmenting the anti-tumor activity of effector killer γδ T cells whilst overcoming the myriad of immune escape mechanisms used by cancer cells.

Abstract
Aging intersects with reproductive senescence in women by promoting a systemic low-grade chronic inflammation that predisposes women to several diseases including ovarian cancer (OC). OC risk at menopause is significantly modified by parity records during prior fertile life. To date, the combined effects of age and parity on the systemic inflammation markers that are particularly relevant to OC initiation and progression at menopause remain largely unknown. Herein, we profiled a panel of circulating cytokines in multiparous versus virgin C57BL/6 female mice at peri-estropausal age and investigated how cytokine levels were modulated by intraperitoneal tumor induction in a syngeneic immunocompetent OC mouse model. Serum FSH, LH and TSH levels increased with age in both groups while prolactin (PRL) was lower in multiparous respect to virgin mice, a finding previously observed in parous women. Serum CCL2, IL-10, IL-5, IL-4, TNF-α, IL1-β and IL-12p70 levels increased with age irrespective of parity status, but were specifically reduced following OC tumor induction only in multiparous mice. Animals developed hemorrhagic ascites and tumor implants in the omental fat band and other intraperitoneal organs by 12 weeks after induction, with multiparous mice showing a significantly extended survival. We conclude that previous parity history counteracts aging-associated systemic inflammation possibly by reducing the immunosuppression that typically allows tumor spread. Results suggest a partial impairment of the M2 shift in tumor-associated macrophages as well as decreased stimulation of regulatory B-cells in aged mice. This long term, tumor-concurrent effect of parity on inflammation markers at menopause would be a contributing factor leading to decreased OC risk.

Abstract
Our previous studies showed that colorectal tumor has high interleukin-4 receptor α (IL-4Rα) expression, whereas adjacent normal tissue has low or no IL-4Rα expression. We also observed that human atherosclerotic plaque-specific peptide-1 (AP1) can specifically target to IL-4Rα. In this study, we investigated the therapeutic efficacy and systemic toxicity of AP1-conjuagted liposomal doxorubicin. AP1 bound more strongly to and was more efficiently internalized into IL-4Rα-overexpressing CT26 cells than CT26 control cells. Selective cytotoxicity experiment revealed that AP1-conjugated liposomal doxorubicin preferentially killed IL-4Rα-overexpressing CT26 cells. AP1-conjugated liposomal doxorubicin administered intravenously into mice produced significant inhibition of tumor growth and showed decreased cardiotoxicity of doxorubicin. These results indicated that AP1-conjugated liposomal doxorubicin has a potent and selective anticancer potential against IL-4Rα-overexpressing colorectal cancer cells, thus providing a model for targeted anticancer therapy.

Targeting IL4/IL4R for the treatment of epithelial cancer metastasis. Clin Exp Metastasis 2015; 32:847-56.

Abstract
While progress has been made in treating primary epithelial tumors, metastatic tumors remain largely incurable and still account for 85-90 % of all cancer-related deaths. Interleukin-4 (IL4), a Th2 cytokine, and the IL4/IL4 receptor (IL4R) interaction have well defined roles in the immune system. Yet, IL4 receptors are over-expressed by many epithelial cancers and could be a promising target for metastatic tumor therapy. The IL4/IL4R signaling axis is a strong promoter of pro-metastatic phenotypes in epithelial cancer cells including enhanced migration, invasion, survival, and proliferation. The promotion of breast cancer growth specifically is also supported in part by IL4-induced glutamine metabolism, and we have shown that IL4 is also capable of inducing glucose metabolism in breast cancer cells. Importantly, there are several types of FDA approved medications for use in asthma patients that inhibit the IL4/IL4R signaling axis. However, these approved medications inhibit both the type I IL4 receptor found on immune cells, and the type II IL4 receptor that is predominantly expressed by some non-hematopoietic cells including epithelial cancer cells. This article reviews existing therapies targeting IL4, IL4R, or IL4/IL4R signaling, and recent findings guiding the creation of novel therapies that specifically inhibit the type II IL4R, while taking into consideration effects on immune cells within the tumor microenvironment. Some of these therapies are currently in clinical trials for cancer patients, and may be exploitable for the treatment of metastatic disease.

Abstract
Interleukin 4 (IL-4) has a variety of immune functions, including helper T-cell (Th-cell) differentiation and innate immune-response processes. However, the impact of IL-4 on gamma delta (γδ) T cells remains unclear. In this study, we investigate the effects of IL-4 on the activation and proliferation of γδ T cells and the balance between variable delta 1 (Vδ1) and Vδ2 T cells in humans. The results show that IL-4 inhibits the activation of γδ T cells in the presence of γδ T-cell receptor (TCR) stimulation in a STAT6-dependent manner. IL-4 promoted the growth of activated γδ T cells and increased the levels of Vδ1 T cells, which in turn inhibited Vδ2 T-cell growth via significant IL-10 secretion. Vδ1 T cells secreted significantly less interferon gamma (IFNγ) and more IL-10 relative to Vδ2. Furthermore, Vδ1 T cells showed relatively low levels of Natural Killer Group 2D (NKG2D) expression in the presence of IL-4, suggesting that Vδ1 T cells weaken the γδ T cell-mediated anti-tumor immune response. For the first time, our findings demonstrate a negative regulatory role of IL-4 in γδ T cell-mediated anti-tumor immunity.

Joshi BH, Leland P, Lababidi S, Varrichio F, Puri RK. Interleukin-4 receptor alpha overexpression in human bladder cancer correlates with the pathological grade and stage of the disease. Cancer Med 2014; 3:1615-28. [PMID: 25208941 PMCID: PMC4298388 DOI: 10.1002/cam4.330] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2014] [Revised: 08/06/2014] [Accepted: 08/06/2014] [Indexed: 12/01/2022] Open
Abstract
Previously, we have demonstrated that interleukin-4 receptor α (IL-4Rα) is overexpressed on a variety of human cancers and can serve as target for IL-4 immunotoxin comprised of IL-4 and a mutated Pseudomonas exotoxin. However, its expression and association with grade and clinical stage of bladder cancer has not been studied. IL-4Rα expression was examined in human bladder cancer cell lines, mouse xenografts, and biopsy specimens at mRNA and protein levels by real-time RT-PCR and IHC/ISH techniques. We also examined the effect of IL-4 on proliferation and invasion of bladder carcinoma cell lines. For tissue microarray (TMA) results, we analyzed the precision data using exact binomial proportion with exact two-sided P-values. We used Cochran–Armitage Statistics with exact two-sided P-values to examine the trend analysis of IL-4Rα over grade or stage of the bladder cancer specimens. The influence of age and gender covariates was also analyzed using multiple logistic regression models. IL-4Rα is overexpressed in five bladder cancer cell lines, while normal bladder and human umbilical vein cell lines (HUVEC) expressed at low levels. Two other chains of IL-4 receptor complex, IL-2RγC and IL-13Rα1, were absent or weakly expressed. IL-4 modestly inhibited the cell proliferation, but enhanced cell invasion of bladder cancer cell lines in a concentration-dependent manner. Bladder cancer xenografts in immunodeficient mice also maintained IL-4Rα overexpression in vivo. Analysis of tumor biopsy specimens in TMAs revealed significantly higher IL-4Rα immunostaining (≥2+) in Grade 2 (85%) and Grade 3 (97%) compared to Grade 1 tumors (0%) (P ≤ 0.0001). Similarly, 9% stage I tumors were positive for IL-4Rα (≥2+) compared to 84% stage II (P ≤ 0.0001) and 100% stages III–IV tumors (P ≤ 0.0001). IL-13Rα1 was also expressed in tumor tissues but at low levels and it did not show any correlation with the grade and stage of disease. However, the IL-2RγC was not expressed. Ten normal bladder specimens demonstrated ≤1+ staining for IL-4Rα and IL-13Rα1 and no staining for IL-2RγC. These results demonstrate that IL-4Rα is overexpressed in human bladder cancer, which correlates with advanced grade and stage of the disease. Thus, IL-4Rα may be a bladder tumor-associated protein and a prognostic biomarker.

Abstract
Interleukin (IL)-4, originally identified as a lymphocyte growth factor, can directly inhibit growth of certain tumor cell types. We reported previously that IL-4 induced cell cycle arrest in G1 phase through an increase in p21(WAF1/CIP1) expression in human renal cell carcinoma (RCC) cell lines. In the present study, we investigated the underlying mechanism of IL-4-induced growth inhibition. In four of six human RCC cell lines, including Caki-1, A498, SNU482, and SNU228, IL-4 induced cellular senescence as demonstrated by enlarged and flattened morphology, increased granularity, and senescence-associated-β-galactosidase (SA-β-gal) staining. Signal tranducer and activator of transcription 6 (STAT6) and p38 MAPK were found to mediate IL-4-induced growth inhibition and cellular senescence. Both of these molecules were activated by 10 min after IL-4 treatment, and inhibition of their activity or expression prevented growth suppression and cellular senescence induced by IL-4. Inhibiting or silencing either STAT6 or p38 MAPK alone partially reduced the effect of IL-4, whereas inhibiting or silencing both molecules exerted an additive effect and almost completely abrogated the effect of IL-4. Thus STAT6 and p38 MAPK appeared to independently mediate IL-4-induced growth inhibition and cellular senescence. The p21(WAF1/CIP1) up-regulation that accompanied growth inhibition and cellular senescence by IL-4 was also attenuated additively when p38 MAPK and STAT6 were silenced. Taken together, these results show that IL-4 induces cellular senescence through independent signaling pathways involving STAT6 and p38 MAPK in some human RCC cell lines.

Abstract
Innate and adaptive immune cells secrete different cytokines, which participate through distinct mechanisms in cell-mediated immunity and humoral immune responses. The aim of this study was to evaluate the immune response through analysis of type 1 (Th1), Th2, and Th17 cells in patients with epithelial ovarian cancer (EOC). Our study included 44 patients with EOC (study group) and 32 gynecological patients with no ovarian disease (control group). Fragments of ovarian tissue and blood samples were collected in both groups and aliquots of intracystic fluid and peritoneal fluid were recovered from the EOC patient group. Interleukin (IL)-2/IL-4/IL-6/IL-10/IL-17/tumor necrosis factor (TNF)-α/interferon (IFN)-γ levels were measured by cytometric bead array. Statistical analysis included chi-squared, Student t, Mann-Whitney, Kruskal-Wallis tests, and Cox regression model. Patients with EOC were associated with higher levels of TNF-α/IL-4/IL-6/IL-10 compared to the control group. Both IL-10 and TNF-α concentrations were higher in patients with stage III/IV EOC and also associated with higher levels of cancer antigen 125. Higher Th1-mediated immune response was observed when the cytoreduction was considered optimal. However, patients with EOC with unsatisfactory cytoreductive surgery and undifferentiated tumors were associated with higher concentrations of Th2 cytokines in the 4 sites studied. Higher IL-6/IL-10 and lower IFN-γ concentrations were also associated with a lower overall survival rate in patients with EOC. The EOC group presented a predominantly Th2 response and an immunosuppressant standard and had association between IL-6/IL-10/IFN-γ and prognosis.

Abstract
The clinical application of chemotherapy to brain tumors has been severely limited because the blood-brain barrier (BBB) often prevents therapeutic levels from being achieved. Here we show that pulsed HIFU and human atherosclerotic plaque-specific peptide-1 (AP-1)-conjugated liposomes containing doxorubicin (AP-1 Lipo-Dox) act synergistically in an experimental brain tumor model. We developed an intracranial brain-tumor model in NOD-scid mice using human brain glioblastoma multiforme (GBM) 8401 cells. Pulsed HIFU was used to transcranially disrupt the BBB in these mouse brains by delivering ultrasound waves in the presence of microbubbles. Prior to each sonication, AP-1 Lipo-Dox or unconjugated Lipo-Dox was administered intravenously, and the concentration in the brains was quantified by fluorometer. Compared to control animals treated with injections of AP-1 Lipo-Dox or unconjugated Lipo-Dox, animals receiving the drug followed by pulsed HIFU exhibited enhanced accumulation of the drug in tumor cells. Drug injection with sonication increased the tumor-to-normal brain doxorubicin ratio of the target tumors by about twofold compared with the control tumors. Moreover, the tumor-to-normal brain ratio was highest after the injection of AP-1 Lipo-Dox with sonication. Combining sonication with AP-1 Lipo-Dox also significantly inhibited tumor growth compared with chemotherapy alone. There was a modest but significant increase in the median survival time in mice treated with AP-1 Lipo-Dox followed by pulsed HIFU, compared to those treated with AP-1 Lipo-Dox without sonication. The use of AP-1-conjugated liposomes carrying cytotoxic agents followed by pulsed HIFU represents a feasible approach for enhanced targeted drug delivery in brain tumor therapies.

Abstract
PURPOSE The origin and pathogenesis of malignant pleural mesothelioma (MPM) are closely aligned with inflammation. MPM tumors express interleukin-4 receptor α (IL-4Rα), the principal subunit of the IL-4 receptor. We set out to determine the biologic function and clinical relevance of IL-4Rα in human MPM. EXPERIMENTAL DESIGN Expression of IL-4Rα by human MPM tumors was determined by quantitative real-time PCR (n = 37) and immunohistochemistry (n = 52). Intracellular cytokine analysis of T-cell-derived IL-4 was carried out on matched tumor and blood samples from eight patients with MPM. Four human MPM cell lines were used to determine the direct effects of IL-4 on MPM tumor cells. RESULTS High tumor mRNA expression of IL-4Rα was an independent predictor of poor survival in patients with epithelial MPM [HR, 3.13, 95% confidence interval (CI), 1.68-7.15; P = <0.0001]. Ninety-seven percent of epithelial MPM tumors and 95% of nonepithelial MPM tumors expressed IL-4Rα protein by immunohistochemistry, and strong IL-4Rα staining correlated with worse survival in patients with epithelial histology (P = 0.04). A greater percentage of tumor-infiltrating T cells produced IL-4 compared with matched blood T cells (21% ± 7% vs. 4% ± 2%, P = 0.0002). In response to IL-4, human MPM cells showed increased STAT-6 phosphorylation and increased production of IL-6, IL-8, and VEGF, without effect on proliferation or apoptosis. CONCLUSIONS Tumor expression of IL-4Rα is inversely correlated with survival in patients undergoing surgical resection for epithelial MPM. Tumor-infiltrating T cells in MPMs are polarized to produce IL-4 and may provide endogenous activation signals to MPM tumor cells in situ. The IL-4/IL-4 receptor axis is a potential therapeutic target in human MPM.

Abstract
Interleukin-4 receptor α (IL-4Rα) chain is highly expressed on the surface of various human solid tumors. We designed a novel hybrid peptide termed IL-4Rα-lytic peptide that targets the IL-4Rα chain. The IL-4Rα-lytic peptide contains a target moiety to bind to IL-4Rα and a cellular toxic lytic peptide that selectively kills cancer cells. The anticancer activity of the IL-4Rα-lytic peptide was evaluated in vitro and in vivo. It was found that the IL-4Rα-lytic peptide has cytotoxic activity in cancer cell lines expressing IL-4Rα, determined by quantitative real-time PCR. The IC(50) ratios of the lytic peptide to the IL-4Rα-lytic peptide correlated well with the expression levels of IL-4Rα on cancer cells (r = 0.80). In addition, IL-4Rα-lytic peptide administered either intratumoraly or intravenously significantly inhibited tumor growth in xenograft model of human pancreatic cancer (BXPC-3) in mice. These results indicate that the IL-4Rα-lytic peptide generated in this study has a potent and selective anticancer potential against IL-4Rα-positive solid cancers.

Abstract
Apigenin, a common plant flavonoid, has been shown to possess anti-tumor properties; however, the underlying molecular mechanisms are still not completely understood. In the present study, we investigated the effects of apigenin on human hepatoma Huh7 cell proliferation, cell cycle distribution, apoptosis, and colony formation in vitro, as well as on the tumorigenicity of Huh7 cells in vivo. To get more insight into the mechanism of apigenin action, we performed genome-wide expression profiling of apigenin-treated Huh7 cells using cDNA microarrays (Agilent Whole Human Genome Oligo Microarray) that contain 41,000 genes. Ten of the most differentially expressed genes (≧5-fold changes) were selected for further evaluation by quantitative RT-PCR (qPCR) and Western blot analyses. Notably, apigenin (5-20 μg/ml) remarkably inhibited Huh7 cell proliferation and colony formation as compared to the vehicle control, which was in a dose-dependent manner. Accompanying with the decreased growth, apigenin-treated cells showed a cell cycle arrest at G2/M phase and an increased rate of apoptosis. Moreover, the xenografts derived from Huh7 cells were significantly (p<0.05) retarded by the delivery of apigenin (50 μg/mouse/day) relative to the control counterparts. Gene expression profile analysis revealed that 1336 genes were up-regulated and 428 genes were down-regulated by apigenin. The down-regulation of interleukin-4 receptor and ubiquitin specific protease 18 and the up-regulation of SLC27A3 and chemokine (C-C motif) receptor 2 were further confirmed by the qPCR and Western blot results. In conclusion, apigenin exhibits inhibitory effects on hepatoma cell growth, which is likely mediated through alteration of gene expression profiles.

Abstract
AIM: To investigate the effects of apigenin on cell growth and gene expression in human hepatoma cell line Huh-7.
METHODS: After Huh-7 cells was cultured and treated with different concentrations of apigenin, cell proliferation was measured by colorimetric methyl thiazolyl tetrazolium (MTT) assay; cell clonogenicity was detected by colony-forming assay; and cell cycle distribution and apoptosis were examined by flow cytometry. The impact of apigenin on the tumorigenicity of Huh-7 cells in nude mice was also detected. The differential gene expression between cells treated and untreated with apigenin was detected by cDNA microarray and verified by quantitative real-time reverse transcription-polymerase chain reaction and Western blot.
RESULTS: Compared with untreated cells, cells treated with apigenin exhibited a marked growth inhibition. The half maximal inhibitory concentration (IC50) of apigenin on cell growth was approximately 10.5 mg/L ± 0.3 mg/L. Apigenin treatment could cause a cell cycle block at G2/M phase, decrease the percentage of cells at G0/G1 phase, promote apoptosis, and inhibit the tumorigenicity of Huh-7 cells in vivo. Apigenin treatment could also dramatically alter the expression of 1 764 functionally related genes in Huh-7 cells. Of these differentially expressed genes, the majority are involved in nucleic acid binding and transport, enzyme catalytic activity regulation, transcriptional regulation, cytoskeletal structure and/or adhesion, signal transduction, metabolism, apoptosis or the immune response. Of note, apigenin could significantly downregulate the expression of interleukin-4 receptor and ubiquitin-specific protease 18.
CONCLUSION: Apigenin partially inhibits Huh-7 cell growth in vitro and in vivo by blocking cell cycle at G2/M phase and promoting apoptosis. Apigenin treatment alters the expression of multiple genes in Huh-7 cells.

Abstract
Imaging or drug delivery tools for atherosclerosis based on the plaque biology are still insufficient. Here, we attempted to identify peptides that selectively home to atherosclerotic plaques using phage display. A phage library containing random peptides was ex viv screened for binding to human atheroma tissues. After three to four rounds of selection, the DNA inserts of phage clones wer sequenced. A peptide sequence, CRKRLDRNC, was the most frequently occurring one. Intravenously injected phage displaying the CRKRLDRNC peptide was observed to home to atherosclerotic aortic tissues of low-density lipoprotein receptor-deficient (Ldlr−/–) mice at higher levels than to normal aortic tissues of wild-type mice. Moreover, a fluorescein- or radioisotope-conjugated synthetic CRKRLDRNC peptide, but not a control peptide, homed in vivo to atherosclerotic plaques in Ldlr−/– mice, while homing of the peptide to other organs such as brain was minimal. The homing peptide co-localized with endothelial cells, macrophages and smooth muscle cells a mouse and human atherosclerotic plaques. Homology search revealed that the CRKRLDRNC peptide shares a motif of interleukin-receptor (IL-4) that is critical for binding to its receptor. The peptide indeed co-localized with IL-4 receptor (IL-4R) at atherosclerotic plaques. Moreover, the peptide bound to cultured cells expressing IL-4R on the cell surface and the binding was inhibited by the knock-down of IL-4R. These results show that the CRKRLDRNC peptide homes to atherosclerotic plaques through binding to IL-4R as its target and may be a useful tool for selective drug delivery and molecular imaging of atherosclerosis.

Abstract
Targeting cell surface receptors with cytotoxins or immunotoxins provides a unique opportunity for tumor therapy. Here, we show the efficacy of the combination therapy of gemcitabine with an interleukin-4 (IL-4) cytotoxin composed of IL-4 and truncated Pseudomonas exotoxin in animal models of pancreatic ductal adenocarcinoma (PDA). We have observed that 42 of 70 (60%) tumor samples from patients with PDA express moderate- to high-density surface IL-4 receptor (IL-4R), whereas normal pancreatic samples express no or low-density IL-4R. IL-4 cytotoxin was specifically and highly cytotoxic [50% protein synthesis inhibition (IC50) ranging from >0.1 to 13 ng/mL] to six of eight pancreatic cancer cell lines, whereas no cytotoxicity (IC50>1,000 ng/mL) was observed in normal human pancreatic duct epithelium cells, fibroblasts, and human umbilical vein endothelial cells (HUVEC). We also showed that IL-4 cytotoxin in combination with gemcitabine exhibited synergistic antitumor activity in vitro. To confirm synergistic antitumor activity in vivo and monitor precise real-time disease progression, we used a novel metastatic and orthotopic mouse model using green fluorescent protein-transfected cancer cells and whole-body imaging system. The combination of both agents caused complete eradication of tumors in 40% of nude mice with small established PDA tumors. In addition, combined treatment significantly prolonged the survival of nude mice bearing day 14 advanced distant metastatic PDA tumors. Similar results were observed in mice xenografted with PDA obtained from a patient undergoing surgical resection. These results indicate that IL-4 cytotoxin combined with gemcitabine may provide effective therapy for the treatment of patients with PDA.

Abstract
Pituitary adenomas are frequently invasive of surrounding tissues, which adversely affects the surgical outcome and the disease-free survival of patients. In the present study, Interleukin 4 receptor (IL-4R) complex has been investigated to figure out whether the three subunits are overexpressed in human invasive pituitary adenomas. Reverse transcription-polymerase chain reaction (RT-PCR) analysis for interleukin 4 receptor alpha (IL-4Ralpha), interleukin 13 receptor alpha1 (IL-13Ralpha1), interleukin 2 receptor gammac (IL-2Rgammac) were performed on total RNA extracted from 10 non-invasive pituitary adenomas, 30 invasive pituitary adenomas, one glioblastoma multiforme, one normal human pituitary tissue sample and one normal human brain tissue sample. Quantitative real-time PCR and in situ immunofluorescence assay were performed in five invasive functioning pituitary adenoma samples and five invasive nonfunctioning pituitary adenoma samples. RT-PCR analysis for IL-4Ralpha, IL-13Ralpha1 and IL-2Rgammac chains were overexpressed in invasive pituitary adenomas. The transcripts for three subunits were not/weakly expressed in normal pituitary tissue and normal brain tissue. The quantitative real-time PCR and in situ immunofluorescence assay confirmed the results of the RT-PCR analysis. Our results indicate that human invasive pituitary adenomas express type III IL-4R complex. These receptors may serve as a novel target for immunotoxin therapy in patients with invasive pituitary adenomas who are not amenable to total surgical resection or for recurrent cases.

Abstract
✓ Targeting cell surface receptors with cytotoxins or immunotoxins provides a unique opportunity for brain tumor therapy. The authors have discovered that receptors for two cytokines, interleukin (IL)-4 and IL-13, are overexpressed on tumor biopsy samples and on cell lines derived from a variety of human tumors, including brain tumors. These investigators have demonstrated that the structure of these cytokine receptors on tumor cells is different from that found on normal immune cells. In human solid tumor cells, IL-4 binds to two chains (IL-4Rα and IL-13Rα1), whereas IL-13 binds to three chains in many solid tumor cells, including glioma cells (to IL-4Rα, IL-13Rα1, and IL-13Rα2). To target IL-4Rs and IL-13Rs, the authors generated two recombinant fusion cytotoxins composed of IL-4 or IL-13 and a mutated form of pseudomonas exotoxin (PE), which for simplicity are called IL4-PE and IL13-PE in this paper. These chimeric cytotoxins are highly toxic in vitro to human tumor cell lines and primary cell cultures, including glioma cells, and in vivo to animal models of human tumors, including gliomas. In contrast, normal cells, including immune, endothelial, and brain cells, are spared from their cytotoxic effects. Based on numerous preclinical studies, IL13-PE (also known as IL13-PE38QQR or cintredekin besudotox) has been tested in four Phase I/II clinical trials. The agent IL13-PE was administered intracranially by using convection-enhanced delivery (CED). The drug was delivered through catheters placed either directly into the tumor bed or in the peritumoral region after resection of the lesion. The CED of IL13-PE was fairly well tolerated, with a reasonable benefit/risk profile for treatment of patients with glioma. Based on Phase I/II clinical trials, the Phase III Randomized Evaluation of CED of IL13-PE Compared to Gliadel Wafer with Survival Endpoint Trial (also known as the PRECISE Trial) in patients with initial recurrence of glioblastoma multiforme has recently been completed. Patients are being monitored for safety of the agents, duration of overall survival, and quality of life.
