Abstract
B7-H3 (CD276), an immune checkpoint molecule, is overexpressed in various types of cancer and their tumor vasculature, demonstrating significant associations with adverse clinical outcomes. In addition to its well-known immune functions, B7-H3 exhibits dual co-stimulatory/co-inhibitory roles in normal physiology and the tumor microenvironment. The non-immune functions of B7-H3 in tumor cells and the tumor vasculature, including promoting tumor cell anti-apoptosis, proliferation, invasion, migration, drug resistance, radioresistance, as well as affecting cellular metabolism and angiogenesis, have increasingly gained attention from researchers. Particularly, the co-expression of B7-H3 in both tumor cells and tumor endothelial cells highlights the higher potential and clinical utility of therapeutic strategies targeting B7-H3. This review aims to summarize the recent advances in understanding the non-immune functions of B7-H3 in tumors and provide insights into therapeutic approaches targeting B7-H3, focusing on its co-expression in tumor cells and endothelial cells. The aim is to establish a theoretical foundation and practical reference for the development and optimization of B7-H3-targeted therapies.

B7-H3 chimeric antigen receptor-modified T cell shows potential for targeted treatment of acute myeloid leukaemia. Eur J Med Res 2023; 28:129. [PMID: 36941687 PMCID: PMC10026503 DOI: 10.1186/s40001-023-01049-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2022] [Accepted: 02/07/2023] [Indexed: 03/23/2023] Open
Abstract
BACKGROUND AND AIMS Chimeric antigen receptor (CAR)-T cell therapy is a novel type of immunotherapy. However, the use of CAR-T cells to treat acute myeloid leukaemia (AML) has limitations. B7-H3 is expressed in several malignancies, including some types of AML cells. However, its expression in normal tissues is low. Therefore, B7-H3 is ideal for targeted AML therapy. MATERIALS AND METHODS First, we constructed B7-H3 CAR that can target B7-H3, and then constructed B7-H3-CAR-T cells in vitro, which were co-incubated with six AML cell lines expressing different levels of B7-H3, respectively. The toxicity and cytokines were detected by flow cytometry. In vivo, AML model was established in B-NSG mice to study the toxicity of B7-H3-CAR T on AML cells. RESULTS In vitro functional tests showed that B7-H3-CAR-T cells were cytotoxic to B7-H3-positive AML tumor cells and had good scavenging effect on B7-H3-expressing AML cell lines, and the cytokine results were consistent. In vivo, B7-H3-CAR-T cells significantly inhibited tumor cell growth in a mouse model of AML, prolonging mouse survival compared with controls. CONCLUSION B7-H3-CAR-T cells may serve as a novel therapeutic method for the targeted treatment of AML.

Abstract
Accumulating evidence supports the active involvement of vascular inflammation in atherosclerosis pathogenesis. Vascular inflammatory events within atherosclerotic plaques are predominated by innate antigen-presenting cells (APCs), including dendritic cells, macrophages, and adaptive immune cells such as T lymphocytes. The interaction between APCs and T cells is essential for the initiation and progression of vascular inflammation during atherosclerosis formation. B7-CD28 family members that provide either costimulatory or coinhibitory signals to T cells are important mediators of the cross-talk between APCs and T cells. The balance of different functional members of the B7-CD28 family shapes T cell responses during inflammation. Recent studies from both mouse and preclinical models have shown that targeting costimulatory molecules on APCs and T cells may be effective in treating vascular inflammatory diseases, especially atherosclerosis. In this review, we summarize recent advances in understanding how APC and T cells are involved in the pathogenesis of atherosclerosis by focusing on B7-CD28 family members and provide insight into the immunotherapeutic potential of targeting B7-CD28 family members in atherosclerosis.

To kill a cancer: Targeting the immune inhibitory checkpoint molecule, B7-H3. Biochim Biophys Acta Rev Cancer 2022; 1877:188783. [PMID: 36028149 DOI: 10.1016/j.bbcan.2022.188783] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/30/2022] [Accepted: 08/19/2022] [Indexed: 12/26/2022]
Abstract
Targeting the anti-tumor immune response via the B7 family of immune-regulatory checkpoint proteins has revolutionized cancer treatment and resulted in punctuated responses in patients. B7-H3 has gained recent attention given its prominent deregulation and immunomodulatory role in a multitude of cancers. Numerous cancer studies have firmly established a strong link between deregulated B7-H3 expression and poorer outcomes. B7-H3 has been shown to augment cancer cell survival, proliferation, metastasis, and drug resistance by inducing an immune evasive phenotype through its effects on tumor-infiltrating immune cells, cancer cells, cancer-associated vasculature, and the stroma. Given the complex interplay between each of these components of the tumor microenvironment, a deeper understanding of B7-H3 signaling properties is inherently crucial to developing efficacious therapies that can target and inhibit these cancer-promoting interactions. This review delves into the various ways B7-H3 acts as an immunomodulator to facilitate immune evasion and promote tumor growth and spread. With post-transcriptional and post-translational modifications giving rise to different active isoforms coupled with recent discoveries of its putative receptors, B7-H3 can perform diverse functions. Here, we first discuss the dual co-stimulatory/co-inhibitory functions of B7-H3 in the context of normal physiology and cancer. We then discuss the crosstalk facilitated by B7-H3 between stromal components and tumor cells that promote tumor growth and metastasis in different populations of tumor cells, associated vasculature, and the stroma. Concurrently, we highlight therapeutic strategies that can exploit these interactions and their associated limitations, concluding with a special focus on the promise of next-gen in silico-based approaches to small molecule inhibitor drug discovery for B7-H3 that may mitigate these limitations.

Abstract
Background Despite advances in B7 homolog 3 protein (B7-H3) based immunotherapy, the development of drug resistance remains a major clinical concern. The heterogeneity and emerging loss of B7-H3 expression are the main causes of drug resistance and treatment failure in targeted therapies, which reveals an urgent need to elucidate the mechanism underlying the regulation of B7-H3 expression. In this study, we identified and explored the crucial role of the transcription factor SPT20 homolog (SP20H) in B7-H3 expression and tumor progression. Methods Here, we performed CRISPR/Cas9-based genome scale loss-of-function screening to identify regulators of B7-H3 in human ovarian cancer cells. Signaling pathways altered by SP20H knockout were revealed by RNA sequencing. The regulatory role and mechanism of SP20H in B7-H3 expression were validated using loss-of-function and gain-of-function assays in vitro. The effects of inhibiting SP20H on tumor growth and efficacy of anti-B7-H3 treatment were evaluated in tumor-bearing mice. Results We identified SUPT20H (SP20H) as negative and eIF4E as positive regulators of B7-H3 expression in various cancer cells. Furthermore, we provided evidence that either SP20H loss or TNF-α stimulation in tumor cells constitutively activates p38 MAPK-eIF4E signaling, thereby upregulating B7-H3 expression. Loss of SP20H upregulated B7-H3 expression both in vitro and in vivo. Additionally, deletion of SP20H significantly suppressed tumor growth and increased immune cells infiltration in tumor microenvironment. More importantly, antibody–drug conjugates targeting B7-H3 exhibited superior antitumor performance against SP20H-deficient tumors relative to control groups. Conclusions Activation of p38 MAPK-eIF4E signaling serves as a key event in the transcription initiation and B7-H3 protein expression in tumor cells. Genetically targeting SP20H upregulates target antigen expression and sensitizes tumors to anti-B7-H3 treatment. Collectively, our findings provide new insight into the mechanisms underlying B7-H3 expression and introduce a potential synergistic target for existing antibody-based targeted therapy against B7-H3.

Abstract
Immune associated cells in the microenvironment have a significant impact on the development and progression of hepatocellular carcinoma (HCC) and have received more and more attention. Different types of immune-associated cells play different roles, including promoting/inhibiting HCC and several different types that are controversial. It is well known that immune escape of HCC has become a difficult problem in tumor therapy. Therefore, in recent years, a large number of studies have focused on the immune microenvironment of HCC, explored many mechanisms worth identifying tumor immunosuppression, and developed a variety of immunotherapy methods as targets, laying the foundation for the final victory in the fight against HCC. This paper reviews recent studies on the immune microenvironment of HCC that are more reliable and important, and provides a more comprehensive view of the investigation of the immune microenvironment of HCC and the development of more immunotherapeutic approaches based on the relevant summaries of different immune cells.

Abstract
Hepatocellular carcinoma (HCC) is characterized by alterations in multiple genes. High expression of CD147 on the surface of HCC cells promotes proliferation. The monoclonal antibody HAb18 recognizes CD147. We constructed an oncolytic adenoviral vector to express HAb18 (ZD55-HAb18) in HCC cells. Interleukin 24 (IL24) was co-expressed through the use of an F2A linker. ZD55-HAb18-IL24 decreased HCC cell viability to a greater degree than either ZD55-HAb18 or ZD55-IL24 alone. ZD55-HAb18-IL24 also induced apoptosis and autophagy in PLC/PRF/5 HCC cells. Intratumoral injection of ZD55-HAb18-IL24 repressed tumor growth in a PLC/PRF/5 xenograft model. Our results suggest that antibody-antitumor gene conjugation elicited a stronger antitumor effect than the antibody alone, and that this strategy could broaden the applications of antibody-based therapies in HCC.

Abstract
B7-H3 is a type I transmembrane co-stimulatory molecule of the B7 family. B7-H3 mRNA is widely distributed in most tissues; however, B7-H3 protein is not constitutively expressed. Few molecules have been shown to mediate the regulation of B7-H3 expression, and their regulatory mechanisms remain unexplored. Recently, TREM-like transcript 2 (TLT-2) has been identified as a potential receptor of B7-H3. However, TLT-2 may not be the only receptor of B7-H3, as B7-H3 has many contradictory roles. As a co-stimulatory molecule, B7-H3 increases the proliferation of both CD4+ and CD8+ T-cells and enhances cytotoxic T-cell activity. However, greatly increased T-cell proliferation and IL-2 levels have been observed in the absence of B7-H3. Thus far, it has been shown that various tumors test positive for B7-H3 expression and that B7-H3 levels correlate with tumor growth, invasion, metastasis, malignant stage, and recurrence rate. Furthermore, transfection of cells with a B7-H3 plasmid and treatment with monoclonal antibodies to block B7-H3 are the main immunotherapeutic strategies for cancer treatment. Several groups have generated anti-B7-H3 antibodies and observed tumor growth suppression in vitro and in vivo. Therefore, it is likely that B7-H3 plays an important role in cancer diagnosis and treatment, aside from its role as a co-stimulatory molecule.

Abstract
Hepatobiliary and pancreatic cancers along with other gastrointestinal malignancies remain the leading cause of cancer-related deaths worldwide. Strategies developed in the recent years on immunotherapy and cancer vaccines in the setting of primary liver cancer as well as in pancreatic cancer are the scope of this review. Significance of orthotopic and autochthonous animal models which mimic and/or closely reflect human malignancies allowing for a prompt and trustworthy analysis of new therapeutics is underlined. Combinational approaches that on one hand, specifically target a defined cancer-driving pathway, and on the other hand, restore the functions of immune cells, which effector functions are often suppressed by a tumor milieu, are shown to have the strongest perspectives and future directions. Among combinational immunotherapeutic approaches a personalized- and individual cancer case-based therapy is of special importance.

Abstract
The B7-CD28 family of ligands and receptors play important roles in T-cell co-stimulation and co-inhibition. Phylogenetically they can be divided into three groups. The recent discovery of the new molecules (B7-H3 [CD276], B7x [B7-H4/B7S1], and HHLA2 [B7H7/B7-H5]/TMIGD2 [IGPR-1/CD28H]) of the group III has expanded therapeutic possibilities for the treatment of human diseases. In this review, we describe the discovery, structure, and function of B7-H3, B7x, HHLA2, and TMIGD2 in immune regulation. We also discuss their roles in important pathological states such as cancers, autoimmune diseases, transplantation, and infection. Various immunotherapeutical approaches are emerging including antagonistic monoclonal antibodies and agonistic fusion proteins to inhibit or potentiate these molecules and pathways in cancers and autoimmune diseases.

Abstract
Mutations in the calreticulin gene (CALR) were recently identified in approximately 70-80% of patients with JAK2-V617F-negative essential thrombocytosis and primary myelofibrosis. All frameshift mutations generate a recurring novel C-terminus. Here we provide evidence that mutant calreticulin does not accumulate efficiently in cells and is abnormally enriched in the nucleus and extracellular space compared to wildtype calreticulin. The main determinant of these findings is the loss of the calcium-binding and KDEL domains. Expression of type I mutant CALR in Ba/F3 cells confers minimal IL-3-independent growth. Interestingly, expression of type I and type II mutant CALR in a nonhematopoietic cell line does not directly activate JAK/STAT signaling compared to wildtype CALR and JAK2-V617F expression. These results led us to investigate paracrine mechanisms of JAK/STAT activation. Here we show that conditioned media from cells expressing type I mutant CALR exaggerate cytokine production from normal monocytes with or without treatment with a toll-like receptor agonist. These effects are not dependent on the novel C-terminus. These studies offer novel insights into the mechanism of JAK/STAT activation in patients with JAK2-V617F-negative essential thrombocytosis and primary myelofibrosis.

Abstract
B7-H3 is a transmembrane protein and a member of the B7 family of immune regulatory ligands. It exerts both inhibitory and stimulatory effects on the activation of T cells. We investigated the expression of B7-H3 in invasive squamous cell carcinoma (ISCC) of the uterine cervix by immunohistochemistry, and aimed to determine whether expression of this factor is involved in the progression of the morphologic spectrum from normal cervical epithelia to cervical intraepithelial neoplasia and cervical ISCC. In addition, we sought to examine the relation of B7-H3 to the abundance of tumor-infiltrating and tumor-associated CD8(+) lymphocytes and to the evidence of phosphohistone H3, which is a core histone protein detected during mitosis. B7-H3 immunostaining was scored with regard to quantity and intensity of positively stained cells, and was noted in membranous and cytoplasmic patterns in epithelial cells and on endothelia of stromal blood vessels. Compared with those in intraepithelial neoplasias, immunoscores were significantly increased in ISCC (P<0.0001 for epithelial and endothelial expression, respectively). High scoring was associated with International Federation of Gynecology and Obstetrics stages IB and higher. Immunoscores of epithelial and endothelial B7-H3 expression were correlated significantly (P=0.0358). Epithelial and endothelial expression of B7-H3 was inversely related with CD8(+) tumor-infiltrating lymphocyte (P<0.0001). Moderate/strong B7-H3 epithelial as well as endothelial expression was mutually increased with intermediate/strong phosphohistone H3 scores (P=0.0396 and P=0.0483, respectively). There was no statistical relation with survival; however, no patient with negative scoring died of her tumor. Our results indicate that B7-H3 expression in cervical ISCC may play an important role in overcoming CD8(+) T-cell immunoregulation to acquire aggressive growth.

Abstract
Hepatitis B virus (HBV) is a major public health problem, and HBV-related acute-on-chronic liver failure (HBV-ACLF) has an extremely poor prognosis due to a lack of effective treatments. B7-H3 and B7-H4 are two novel members of the B7 superfamily that are actively involved in regulating the pathogenesis of infectious diseases. However, the intrahepatic expression of both members in HBV-ACLF patients has yet to be described. In this study, we analyzed the expression of B7-H3 and B7-H4 in HBV-ACLF biopsies by immunohistochemistry. Our results showed that both members were observed in all HBV-ACLF samples, and their expression was chiefly observed on infiltrating inflammatory cells and the damaged bile ducts. Immunofluorescence double staining showed that B7-H4 was expressed chiefly on CD3(+) T cells, CD68(+) macrophages, CK-18(+) bile ducts, and CD31(+) endothelial cells, while B7-H3 was found on all cell types detected. The expression of the programmed death (PD)-1 ligands, PD-L1 and PD-L2, was also detected in these liver tissues and they were found to be co-expressed with B7-H3 and B7-H4. These results suggest that the B7-family signaling is most likely to affect the pathogenesis of this disease, and a clear understanding of their functional roles may further elucidate the disease process.

Abstract
The B7 family consists of activating and inhibitory molecules that regulate immune responses. Recent research demonstrated the roles of soluble B7-H3 (sB7-H3) and soluble B7-H1 (sB7-H1) in the blood serum of various tumors; however, none of these studies investigated the expression of these proteins in the cerebral spinal fluid (CSF) and blood serum of patients with glioma. The aim of the present study was to investigate the expression of B7-H3 and B7-H1 in the CSF, blood serum and tissues of patients with glioma and their correlation with clinicopathological data. Between January 2012 and November 2012, samples were obtained from 78 patients with glioma, four CSF samples were obtained from patients with a moderate traumatic brain injury, four brain tissue samples were obtained from patients with a traumatic brain injury and 40 blood serum samples were obtained from healthy individuals. The expression of B7-H3 and B7-H1 in the CSF, blood serum and tumor samples of the patients with high-grade glioma was found to be higher than that in the patients with low-grade glioma. However, no significant differences in sB7-H3 and sB7-H1 expression were observed in the blood serum of the patients with glioma compared with the healthy control subjects. In addition, the expression of sB7-H3 and sB7-H1 in the CSF of the patients with glioma was higher than that in the CSF of the patients with a moderate traumatic brain injury. Furthermore, in the patients with glioma, B7-H3 and B7-H1 expression in the CSF and tumor tissue, although not in the blood serum, correlated with the glioma grade.

Abstract
INTRODUCTION Chromogranin A is a neuroendocrine secretory product and its loss is a feature of malignant NEN de-differentiation. We hypothesized that chromogranin A fragments were differentially expressed during NEN metastasis and played a role in the regulation of NEN proliferation. METHODS Chromogranin A mRNA (PCR) and protein (ELISA/western blot) were studied in 10 normal human mucosa, 5 enterochromaffin cell preparations, 26 small intestinal NEN primaries and 9 liver metastases. Cell viability (WST-1 assay), proliferation (bromodeoxyuridine ELISA) and expression of AKT/AKT-P (CASE ELISA/western blot) in response to chromogranin A silencing, inhibition of prohormone convertase and mTOR inhibition (RAD001/AKT antisense) as well as different chromogranin A fragments were examined in 4 SI-NEN cell lines. RESULTS Chromogranin A mRNA and protein levels were increased (37-340 fold, p<0.0001) in small intestinal NENs compared to normal enterochromaffin cells. Western blot identified chromogranin A-associated processing bands including vasostatin in small intestinal NENs as well as up-regulated expression of prohormone convertase in metastases. Proliferation in small intestinal NEN cell lines was decreased by silencing chromogranin A as well as by inhibition of prohormone convertase (p<0.05). This inhibition also decreased secretion of chromogranin A (p<0.05) and 5-HT (p<0.05) as well as expression of vasostatin. Metastatic small intestinal NEN cell lines were stimulated (50-80%, p<0.05) and AKT phosphorylated (Ser473: p<0.05) by vasostatin I, which was completely reversed by RAD001 (p<0.01) and AKT antisense (p<0.05) while chromostatin inhibited proliferation (~50%, p<0.05). CONCLUSION Chromogranin A was differentially regulated in primary and metastatic small intestinal NENs and cell lines. Chromogranin A fragments regulated metastatic small intestinal NEN proliferation via the AKT pathway indicating that CgA plays a far more complex role in the biology of these tumors than previously considered.

Abstract
Objective To investigate the synergistic anti-tumor effect of QHF (a Chinese medicine formula with anti-tumor active ingredients, including 800 mg/kg Cinobufotalin, 14 mg/kg Ginsenoside Rg3, 5.5 mg/kg Notoginseng and 100 mg/kg Lentinan) when combined with the chemotherapy drug cisplatin (DDP). Methods Hepatocellular carcinoma H22 cells were implanted into mice and after the transplants were successfully established the animals were divided into four groups, namely a normal saline(NS) control group, QHF group, DDP group and QHF+DDP group. The tumor growth was monitored and the survival time determined. In vitro studies employing H22 cells used the first three groups, and determined the effects of QHF and DDP on tumor cell cycle distribution, apoptosis and morphologic changes in vitro. Results QHF significantly inhibited the growth of tumors and prolonged the survival time of mice with hepatocellular carcinomas. QHF combined with DDP could attenuate DDP-induced leucopenia, spleen and thymus atrophy and other indicators of toxicity. The inhibition rate of tumor growth reached 82.54% with QHF+DDP, and QHF prolonged the life span of DDP-treated mice by 66.83%. In the in vitro experiments tumor cells showed morphological changes characteristic of apoptosis by both light and transmission electron microscopy in the QHF group, and the apoptosis rate was 33.85%. Moreover, the proportion of cells in the G0/G1 phase was increased and those in the S-phase decreased. Conclusion QHF combined with DDP could significantly inhibit tumor growth, induce the apoptosis of tumor cells and effectively attenuate DDP toxicity.

Abstract
B7-H3, a novel B7 family member, positively or negatively regulates T-cell responses. We investigated the clinical relevance and prognostic significance of B7-H3 in hepatocellular carcinoma (HCC). Western blotting showed B7-H3 upregulation in 17 of 24 (70.8 %) HCC tissues compared with nontumor liver tissues (p = 0.028). B7-H3 immunostaining on tissue microarrays containing 240 HCC patient samples indicated that 225 (93.8 %) tumors had aberrant B7-H3 expression, with strong intensity in 79 (32.9 %) cases, whereas B7-H3 expression in peritumor liver cells was weak in most cases (226; 94.2 %). Notably, patients with high/moderate tumor cell B7-H3 expression showed significantly poorer survival (p = 0.009) and increased recurrence (p = 0.002). After multivariable adjustment, high/moderate B7-H3 expression remained significant for an increased risk of recurrence (hazard ratio = 1.79; 95 % confidence interval = 1.19-2.70; p = 0.005). B7-H3 expression correlated with invasive phenotypes like vascular invasion and advanced tumor stage, and the metastatic potential of HCC cell lines. Flow cytometry showed that B7-H3 expression is inversely correlated with proliferation and interferon-γ production by infiltrating T cells. Interferon-γ stimulation significantly upregulated B7-H3 expression in HCC cells in vitro, implicating B7-H3 expression as a feedback mechanism to evade anti-tumor immunity. Importantly, the prognostic value of B7-H3 expression was validated in an independent cohort of 206 HCC patients. Collectively, our data suggest that B7-H3 was abundantly expressed in HCC and was associated with adverse clinicopathologic features and poor outcome. Thus, B7-H3 represents an attractive target for diagnostic and therapeutic manipulation in human HCC.

Abstract
In colorectal cancer there is a need for molecular markers that can complement the histopathological staging in predicting the likelihood of disease recurrence following curatively intended surgery. B7-H3 is an immunoregulatory protein shown to be overexpressed in several cancer forms, often associated with more advanced disease and poor prognosis. We wanted to examine whether B7-H3 could be a potential prognostic marker in colorectal cancer. Paraffin-embedded samples from 277 colorectal cancer patients were immunostained with anti-B7-H3 antibody. B7-H3 was expressed in the tumor cell cytoplasm and cell membrane in 62% and 46% of the samples, respectively. Unexpectedly, B7-H3 was expressed in the nucleus in 30% of the tumors. The nuclear localization was confirmed by Western immunoblotting of subcellular fractions. Importantly, in colon cancer, nuclear B7-H3 expression was independently and significantly associated with reduced metastasis-free, disease-specific and overall survival. B7-H3 expression in tumor-associated vasculature and fibroblasts was observed in the majority of samples, and endothelial B7-H3 expression was also significantly associated with poor outcome in colon cancer. In rectal cancer patients, the only significant association was between fibroblast B7-H3 expression and shorter metastasis-free survival. Few significant associations to clinicopathological parameters were seen. The results indicate that nuclear B7-H3 might be involved in colon cancer progression and metastasis, and suggest that nuclear B7-H3 could become a useful prognostic marker in colon cancer.

Abstract
INTRODUCTION Tumors may shift the phenotype and function of dendritic cells (DC) toward the induction of tolerance. In the status of full maturity, DC express a multitude of T cell costimulatory molecules enabling them to induce immune reactions, whereas nonactivated resident DC lack these T cell stimulating capacities. Therefore, we investigated the changes in DC phenotype and expression of B7-H molecules induced by non-small cell lung cancer (NSCLC). METHODS The expression of T cell coinhibitory B7 molecules (B7-DC, B7-1, B7-2, B7-H1, B7-H3) on DC isolated from malignant and nonmalignant lung and lymph node tissue from patients attending curative surgery for NSCLC (n = 12) was analyzed. T cell stimulatory functions of DC isolated from malignant and nonmalignant lung and lymph node tissue samples were measured by allogeneic mixed lymphocyte reactions. Furthermore, the secretion of IL-10 and IL-12p40 by DC was analyzed (enzyme-linked immunosorbent assay). RESULTS : B7-H3 was significantly upregulated in tumor-residing DC, whereas the expression of other B7 molecules, such as B7-DC, B7-1, B7-2, B7-H1, remained unchanged. Significantly reduced levels of T cell proliferation in mixed lymphocyte reactions with tumor-derived DC were recorded. Moreover, elevated concentrations of IL-10 were measured in tumor-derived DC, whereas IL-12 levels were reduced. CONCLUSION Our data indicate that (1) DC derived from NSCLC are immunosuppressive, and (2) under tumor conditions the coinhibitory molecule B7-H3 plays a crucial role in mediating the T cell suppressive effects of DC.

Abstract
Tumor-induced angiogenesis has been shown to suppress immune responses. One mechanism is to suppress leukocyte-endothelial cell interaction by down-regulating the expression of adhesion molecules, such as intercellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1 and E-selectin on the tumor endothelium, which enables tumor cells to escape immune surveillance. Calreticulin (CRT), a chaperone protein mainly located in the endoplasmic reticulum, has been shown to exert anti-angiogenic activity and inhibit tumor growth. Here, we demonstrate that in addition to inhibiting angiogenesis, CRT also enhances the expression of both ICAM-1 and VCAM-1 on tumor endothelial cells. This expression results in enhanced leukocyte-endothelial cell interactions and increased lymphocyte infiltration into tumors. Therefore, combining intramuscular CRT gene transfer with intratumoral cytokine gene therapies significantly improves the antitumor effects of immunotherapy by markedly increasing the levels of tumor-infiltrating lymphocytes. This combined treatment increased the levels of infiltrating lymphocytes to those achieved using four times the cytokine dosage. The combined therapy also resulted in lower levels of immunosuppressive molecules and higher levels of activated T-cells in the tumor microenvironment than immunotherapy alone. In conclusion, this study describes a new antitumor mechanism of CRT that involves the up-regulation of tumor endothelial adhesion molecules and the enhanced infiltration of tumor-specific lymphocytes. Thus, CRT treatment can make tumor cells more vulnerable to immunotherapy and improve the therapeutic efficacy of immunotherapy.

Abstract
Matrine, one of the main components extracted from a traditional Chinese herb, Sophora flavescens Ait, has displayed anti-cancer activity in several types of cancer cells. This study aims to evaluate the therapeutic benefits of matrine on primary and metastatic breast cancer. Matrine inhibited the viability of and induced apoptosis in human MCF-7 and mouse 4T1 breast cancer cells in a dose-dependent manner in vitro as shown by MTT assay, flow cytometry and laser scanning confocal microscopy. Administration of matrine inhibited the growth of primary tumors and their metastases to lungs and livers, in a dose-dependent manner, in a highly metastatic model of 4T1 breast cancer established in syngeneic Balb/c mice. Tumors from matrine-treated mice had a smaller proliferation index, shown by immunostaining with an anti-Ki-67 antibody, a greater apoptosis index, shown by TUNEL-staining, and a less microvessel density, shown by immunostaining with an anti-CD31 A antibody, compared to the controls. Western blot analysis of tumoral homogenates indicated that matrine therapy reduced the ratio of Bcl-2/Bax, downregulated the expressions of VEGF and VEGFR-2, and increased the activation of caspase-3 and caspase-9. This study suggests matrine may be a potent agent, from a natural resource, for treating metastatic breast cancer because of its anti-apoptotic, anti-proliferative and anti-angiogenic activities.

Abstract
B7-H3 is one of the most recently identified members of the B7/CD28 superfamily of costimulatory molecules serving as an accessory modulator of T-cell response. Recently, B7-H3 expression has been reported in several human cancers indicating an additional function of B7-H3 as a regulator of antitumor immunity. However, its precise physiologic role is still elusive, because both stimulatory and inhibitory capacities have been demonstrated. This paper summarizes the available data on B7-H3 in the regulation of T-cell response focusing on its potential role in antitumor immunity.

Abstract
Monoclonal antibodies have the potential to target therapy for high-grade gliomas. Monoclonal antibody 8H9 is specific for membrane protein B7H3 and is reactive with most human high-grade gliomas. We tested the 8H9scFv-PE38 recombinant Pseudomonas immunotoxin in a preclinical model of high-grade glioma. The half maximal inhibitory concentration (IC(50)) of 8H9scFv-PE38 in vitro was determined using glioblastoma cell lines U87 and U251. Maximum tolerated infusion dose of 8H9scFv-PE38 following interstitial infusion to the striatum and pons was defined using athymic rats. Maximum tolerated infusion dose of 8H9scFv-PE38 or PBS control were interstitially delivered to athymic rats xenografted with U87 in the striatum or brain stem. Radiographic response and survivals were measured and compared between treatment groups. The in vitro IC(50) of 8H9scFv-PE38 for U87 was 1,265 ng/mL and, for U251, 91 ng/mL. The maximum tolerated infusion doses of interstitially infused 8H9scFv-PE38 to the striatum and brain stem were 0.75 and 1.8 mug, respectively. For rats harboring intracranial U87 xenografts, infusion of 8H9scFv-PE38 increased mean survival (striatum, 43.4 versus 24.6 days; brain stem, 80.6 versus 45.5 days; n = 28 total) and produced three long-term survivors past 120 days. None of the 14 placebo-treated animals survived >54 days. Tumors also showed volumetric response to infusion of 8H9scFv-PE38 by magnetic resonance imaging. Interstitial infusion of 8H9scFv-PE38 shows potential for the treatment of hemispherical and brain stem glioma. Mol Cancer Ther; 9(4); 1039-46. (c)2010 AACR.

Abstract
Arsenic trioxide (ATO) is of limited therapeutic benefit for the treatment of solid tumors. Genistein exhibits anticancer and pro-oxidant activities, making it a potential candidate to enhance the efficacy of ATO whose cytotoxicity is oxidation-sensitive. This study sought to determine whether genistein synergizes with ATO to combat hepatocellular carcinoma (HCC). Three human HCC cell lines, namely HepG2, Hep3B, and SK-Hep-1, were incubated with ATO, genistein, or ATO + genistein. The cells were also pretreated with antioxidant agents N-acetyl-L-cysteine (NAC) or butylated hydroxyanisole (BHA). Cell viability, apoptosis, intracellular reactive oxygen species (ROS), mitochondrial membrane potential (DeltaPsim), expression of Bcl-2, Bax, caspase-9, and -3, and release of cytochrome c into the cytosol were examined. The synergistic effect of ATO and genistein was also assessed using HepG2 xenografts subcutaneously established in BALB/c nude mice. The results show that genistein synergized with ATO to reduce viability, induce apoptosis, and diminish the DeltaPsim of cells. The combination therapy down-regulated Bcl-2 expression, up-regulated Bax expression, enhanced the activation of caspase-9 and -3, and increased the release of cytochrome c. The synergistic effect of ATO and genistein was diminished by pretreatment with NAC or BHA. Genistein increased the production of intracellular ROS, while ATO had little effect. Genistein synergized with a low dose of ATO (2.5 mg/kg) to significantly inhibit the growth of HepG2 tumors, and suppress cell proliferation and induce apoptosis in situ. There were no obvious side effects, as seen with a high dose of ATO (5 mg/kg). Combining genistein with ATO warrants investigation as a therapeutic strategy to combat HCC.

Abstract
Antiangiogenesis, e.g., inhibition of blood vessel growth, is being investigated as a way to prevent the growth of tumors and other angiogenesis-dependent diseases. Pharmacological inhibition interferes with the angiogenic cascade or the immature neovasculature with synthetic or semi-synthetic substances, endogenous inhibitors or biological antagonists.The chick embryo chorioallantoic membrane (CAM) is an extraembryonic membrane, which serves as a gas exchange surface and its function is supported by a dense capillary network. Because its extensive vascularization and easy accessibility, CAM has been used to study morphofunctional aspects of the angiogenesis process in vivo and to study the efficacy and mechanism of action of pro- and anti-angiogenic molecules. The fields of application of CAM in the study of antiangiogenesis, including our personal experience, are illustrated in this review article.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancer-related causes of death, and conventional treatments offer unsatisfactory response. We have previously reported that kallistatin gene therapy suppressed the growth of HCC tumors by its anti-angiogenic activity, and meloxicam, a selective COX-2 inhibitor, inhibited proliferation and induced apoptosis of human HCC cells in vitro. The aim of this study was to determine whether combining kallistatin gene therapy and meloxicam could offer a better therapeutic effect to combat HCC in mice. A kallistatin expression plasmid was constructed and its expression was detected after intratumoral gene transfer. Both kallistatin gene therapy and meloxicam suppressed the growth of subcutaneous human HepG2 tumors established in BALB/c nude mice, and the combinational therapy showed a stronger effect in suppressing tumor growth, tumor angiogenesis and cell proliferation, and increasing cell apoptosis, than the respective monotherapies. Gene transfer of kallistatin inhibited tumor angiogenesis, and slightly inhibited cell proliferation and increased cell apoptosis in situ, but had no effect on expression of vascular endothelial growth factor, basic fibroblast growth factor, proliferating cell nuclear antigen, Bcl-2, Bax, or activation of caspase-3. Meloxicam therapy inhibited cell proliferation, induced cell apoptosis, reduced expression of proliferating cell nuclear antigen, increased activation of caspase-3, and upregulated Bax. Meloxicam also slightly inhibited tumor angiogenesis with no effect on the expression of vascular endothelial growth factor or basic fibroblast growth factor. Combining two novel anticancer agents, kallistatin targeting tumoral vascularization and meloxicam targeting cell proliferation and apoptosis, warrants investigation as a therapeutic strategy to combat HCC.

Abstract
The clinical benefit of gemcitabine for pancreatic cancer is low due to chemoresistance. Nuclear factor (NF)-kappaB, constitutively activated in pancreatic cancer, is a therapeutic target as it upregulates expression of genes controlling proliferation, apoptosis and angiogenesis. This study aimed to investigate whether downregulation of the p65 subunit of NF-kappaB by siRNA could enhance the efficacy of gemcitabine to treat pancreatic cancer. p65 siRNA synergized with gemcitabine to inhibit the proliferation and induce the apoptosis of pancreatic cancer cells in vitro and in vivo, and suppress the growth and angiogenesis of pancreatic tumors in nude mice. The mechanisms involved inhibition of NF-kappaB activity and consequent inhibition of Bcl-2, cyclin D1 and VEGF, and activation of caspase-3. The results suggest that downregulation of NF-kappaB p65 potentiates the efficacy of gemcitabine in combating pancreatic cancer.

Abstract
SUMMARY B7-H3 and B7-H4 belong to a new class of immune regulatory molecules, which primarily execute their functions in peripheral tissues to fine tune immune responses in target organs. In normal circumstances, while the mRNA for both molecules is broadly distributed, tight control at the post-transcriptional level is imposed. Under a pathogenic environment, such as inflammation and cancer, the control is often aberrant. Upon engaging their receptors, these molecules regulate the immune response in positive or negative ways depending on the expression and type of cells bearing the receptors. Thus, manipulation of the expression of these molecules and/or their receptors may represent a realistic opportunity to fine tune immune responses and to design new immunotherapeutic approaches.

Abstract
OBJECTIVES This study investigated the role of hypoxia-inducible factor 1alpha (HIF-1alpha) in acute pancreatitis (AP) and whether HIF-1alpha is involved in the therapeutic effects of hyperbaric oxygen (HBO) on AP. METHODS Thirty Wistar rats with taurocholate-induced AP were randomly assigned to 3 groups (each group had 10 rats) receiving oxygen, HBO, or no therapeutic treatment 4 hours after induction. Ten healthy sham-operated rats also served as controls. The arterial oxygen saturation, PaO2, pH, lactate dehydrogenase in the arterial sera, and amylase and tumor necrosis factor alpha in the venous sera were measured 6 hours after induction. Pancreatic tissues were subjected to histopathologic analysis, immunohistochemical and Western-blotted analyses of HIF-1alpha and vascular endothelial growth factor, and measuring of myeloperoxidase activity. RESULTS The HBO therapy attenuated the severity of acute pancreatitis; reduced histopathologic scores, dry weight-wet weight ratio of pancreatic tissues, and levels of amylase and lactate dehydrogenase; and elevated blood arterial oxygen saturation, PaO2, and pH values. The HBO therapy inhibited AP-induced up-regulation of HIF-1alpha and its downstream effector vascular endothelial growth factor and the production of tumor necrosis factor alpha and myeloperoxidase activity. CONCLUSIONS Hypoxia-inducible factor 1alpha plays a key role in the pathogenesis of AP, and the ability to down-regulate the expression of HIF-1alpha may partially explain the therapeutic effect of HBO on AP.

Abstract
Cathepsin P is a member of a family of placentally expressed cathepsins (PECs). The closest human homolog of cathepsin P is cathepsin L, a broad specificity enzyme that has functions in many tissues in addition to placenta. The gene duplications that gave rise to the PECs provide a rare opportunity to define proteolytic functions in placenta, a transient organ unique to mammals. Peptidyl substrate and inhibitor libraries have shown that cathepsin P has evolved an unusually restricted preference for substrates containing hydrophobic amino acids. Proteomic techniques were used to probe for substrates of this enzyme. Recombinant cathepsin P was incubated with rat choriocarcinoma (Rcho-1) cell proteins to identify substrates using two-dimensional difference gel electrophoresis. Substrate proteins were excised from gels and characterized by trypsin digestion and MALDI MS/MS. Two endoplasmic reticulum (ER) proteins, gp96 and calreticulin, emerged as potential substrates, and western blotting showed that these proteins are processed by cathepsin P from their C-terminus, removing the KDEL ER retention signal. Immunohistochemistry showed that a portion of cathepsin P co-localizes with calreticulin in Rcho-1 cells. Extracellular calreticulin induces differentiation of Rcho-1 cells, indicating a potential role of cathepsin P in processing and secretion of calreticulin during differentiation of trophoblast giant cells.

Abstract
Hepatitis B virus (HBV) is a major causative agent of hepatocellular carcinoma (HCC) but the pathogenesis remains poorly understood. To provide novel insights into the pathogenesis of HBV, we examined the expression profile of HBV-positive HepG2.2.15 and -negative HepG2 cells. Genes that were markedly up- or down-regulated in the presence of HBV are involved in signal transduction, apoptosis, transcriptional regulation, protein degradation and oncogenesis. Among the analyzed co-signaling molecules CD40, CD80, CD86, B7-H1, B7-DC, OX40, and B7RP-1, CD40 was the only one up-regulated. Following establishment of stable HepG2 cell lines transfected with HBV genes, we found that HBxAg up-regulated the expression of CD40. We also found that CD40 activation by CD40L could promote the expression of negative co-signaling molecule B7-H1, rather than induce the apoptosis of HepG2HBx cell as expected. These results suggest that CD40 up-regulation by HBxAg may play a facilitating role in the pathogenesis causing HCC.

Abstract
Calreticulin is an ER (endoplasmic reticulum) luminal Ca2+-buffering chaperone. The protein is involved in regulation of intracellular Ca2+ homoeostasis and ER Ca2+ capacity. The protein impacts on store-operated Ca2+ influx and influences Ca2+-dependent transcriptional pathways during embryonic development. Calreticulin is also involved in the folding of newly synthesized proteins and glycoproteins and, together with calnexin (an integral ER membrane chaperone similar to calreticulin) and ERp57 [ER protein of 57 kDa; a PDI (protein disulfide-isomerase)-like ER-resident protein], constitutes the ‘calreticulin/calnexin cycle’ that is responsible for folding and quality control of newly synthesized glycoproteins. In recent years, calreticulin has been implicated to play a role in many biological systems, including functions inside and outside the ER, indicating that the protein is a multi-process molecule. Regulation of Ca2+ homoeostasis and ER Ca2+ buffering by calreticulin might be the key to explain its multi-process property.

Abstract
Developmentally regulated endothelial cell locus-1 (Del1) is an embryonic angiogenic factor expressed in early embryonic endothelial cells, but recently has been found to be expressed in some forms of cancers including colon and breast cancers, and melanoma, and human cancer cell lines. Overexpression of Del1 accelerates tumor growth by enhancing vascular formation, implying Del1 may be a potential target for anti-angiogenic cancer therapy. The study aims to investigate whether downregulation of Del1 could inhibit the growth of tumors established in nude Balb/c mice by subcutaneous implantation of human LS-174T colon cancer cells. The shRNA expression vectors targeting human Del1, and vascular endothelial growth factor (VEGF) were constructed. Gene transfection of Del1-shRNA downregulated expression of Del1 in LS-174T cells in vivo and in vitro, but did not alter the proliferative or survival properties of cells in vitro. Gene transfection of VEGF-shRNA downregulated expression of both VEGF and Del1 in LS-174T cells in vivo and in vitro. Both Del1-shRNA and VEGF-shRNA gene therapies exhibited anti-tumor activities and they also showed a synergistic effect in suppressing growth of colon tumors by anti-angiogenesis and anti-proliferation. Although further investigation to clarify the mechanisms explaining the role of Del1 in tumor growth, and the interaction between VEGF and Del1, is required, the results indicate that downregulation of Del1 presents a potent therapeutic strategy to combat colon cancer.

Abstract
T-cell activation requires the interaction of the T-cell receptor with a cognate major histocompatibility complex (MHC)-peptide complex. Initiated by antigen engagement, the adaptive immune response is orchestrated by a complex balance between stimulatory and inhibitory signals that are predominantly controlled by members of the B7 family. Here, we review the current knowledge on B7 family members concerning their constitutive and regulated expression, modulation of the immune response and their role in the evasion of host immune surveillance. We also discuss recent therapeutic strategies that aim to improve immune-cell recognition of tumors and induce tolerance to autoreactive immune responses in normal tissues by manipulating B7 functions.

Abstract
Hepatocellular carcinoma (HCC), one of the most common cancers worldwide, is resistant to anticancer drugs. Hypoxia is a major cause of tumor resistance to chemotherapy, and hypoxia-inducible factor (HIF)-1 is a key transcription factor in hypoxic responses. We have previously demonstrated that gene transfer of an antisense HIF-1alpha expression vector downregulates expression of HIF-1alpha and vascular endothelial growth factor (VEGF), and synergizes with immunotherapy to eradicate lymphomas. The aim of the present study was to determine whether gene transfer of antisense HIF-1alpha could enhance the therapeutic efficacy of doxorubicin to combat HCC. Both antisense HIF-1alpha therapy and doxorubicin suppressed the growth of subcutaneous human HepG2 tumors established in BALB/c nude mice, tumor angiogenesis, and cell proliferation, and induced tumor cell apoptosis. The combination therapy with antisense HIF-1alpha and doxorubicin was more effective in suppressing tumor growth, angiogenesis, and cell proliferation, and inducing cell apoptosis than the respective monotherapies. Gene transfer of antisense HIF-1alpha downregulated the expression of both HIF-1alpha and VEGF, whereas doxorubicin only downregulated VEGF expression. Antisense HIF-1alpha and doxorubicin synergized to downregulate VEGF expression. Both antisense HIF-1alpha and doxorubicin inhibited expression of proliferating cell nuclear antigen, and combined to exert even stronger inhibition of proliferating cell nuclear antigen expression. Antisense HIF-1alpha therapy warrants investigation as a therapeutic strategy to enhance the efficacy of doxorubicin for treating HCC.

Abstract
BACKGROUND The current treatments for hepatocellular carcinoma (HCC) are poor, particularly for metastatic HCC. Intraportal transfusion of adeno-associated virus (AAV) leads to long-term and persistent transgenic expression in livers. Kallistatin, a novel angiogenesis inhibitor, exhibits anti-tumor activity. The aim of the study was to investigate whether intraportal injection of AAV-kallistatin could suppress local and metastatic HCC in mice. METHODS An AAV vector encoding kallistatin was constructed, and its transduction efficiency by intraportal transfusion in livers was examined by RT-PCR, immunohistochemical and Western blotting analysis. The anti-tumor activity was tested in three HCC models including hepatic and subcutaneous human Hep3B HCC tumors in BALB/c athymic (nu/nu) mice, and subcutaneous mouse BNL HCC tumors in BALB/c mice. Tumor cell proliferation in situ was examined by anti-Ki-67 staining, and apoptosis by TUNEL. RESULTS Gene transfection by rAAV-kallistatin inhibited proliferation of human umbilical vein endothelial cells and HCC cells in vitro. Intraportal injection of rAAV-kallistatin resulted in persistent and specific expression of kallistatin in livers detected by RT-PCR and immunohistochemical analysis, and kallistatin protein in circulation detected by Western blotting analysis. Intraportal injection of rAAV-kallistatin significantly suppressed angiogenesis and growth of hepatic Hep3B tumors. The kallistatin released by hepatocytes into the circulation suppressed remote Hep3B and BNL tumors established subcutaneously. The rAAV-kallistatin gene therapy significantly inhibited tumor cell proliferation and induced apoptosis. CONCLUSIONS Intraportal injection of rAAV-kallistatin suppressed hepatic and subcutaneous HCC tumors, relying on its anti-angiogenic and anti-proliferative activities.

Abstract
The B7 family member B7-H3 (CD276) plays important roles in immune responses. However, the function of B7-H3 remains controversial. We found that murine B7-H3 specifically bound to Triggering receptor expressed on myeloid cells (TREM)-like transcript 2 (TLT-2, TREML2). TLT-2 was expressed on CD8(+) T cells constitutively and on activated CD4(+) T cells. Stimulation with B7-H3 transfectants preferentially up-regulated the proliferation and IFN-gamma production of CD8(+) T cells. Transduction of TLT-2 into T cells resulted in enhanced IL-2 and IFN-gamma production via interactions with B7-H3. Blockade of the B7-H3:TLT-2 pathway with a mAb against B7-H3 or TLT-2 efficiently inhibited contact hypersensitivity responses. Our results demonstrate a direct interaction between B7-H3 and TLT-2 that preferentially enhances CD8(+) T cell activation.
