Multifaceted roles of lymphatic and blood endothelial cells in the tumor microenvironment of hepatocellular carcinoma: A comprehensive review. World J Hepatol 2024; 16:537-549. [PMID: 38689749 PMCID: PMC11056903 DOI: 10.4254/wjh.v16.i4.537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 01/11/2024] [Accepted: 03/18/2024] [Indexed: 04/24/2024] Open
Abstract
The tumor microenvironment is a complex network of cells, extracellular matrix, and signaling molecules that plays a critical role in tumor progression and metastasis. Lymphatic and blood vessels are major routes for solid tumor metastasis and essential parts of tumor drainage conduits. However, recent studies have shown that lymphatic endothelial cells (LECs) and blood endothelial cells (BECs) also play multifaceted roles in the tumor microenvironment beyond their structural functions, particularly in hepatocellular carcinoma (HCC). This comprehensive review summarizes the diverse roles played by LECs and BECs in HCC, including their involvement in angiogenesis, immune modulation, lymphangiogenesis, and metastasis. By providing a detailed account of the complex interplay between LECs, BECs, and tumor cells, this review aims to shed light on future research directions regarding the immune regulatory function of LECs and potential therapeutic targets for HCC.

Abstract
Angiogenesis is a process that drives breast cancer (BC) progression and metastasis, which is linked to the altered inflammatory process, particularly in triple-negative breast cancer (TNBC). In targeting inflammatory angiogenesis, natural compounds are a promising option for managing BC. Thus, this study was designed to determine the natural alkaloid sanguinarine (SANG) potential for its antiangiogenic and antimetastatic properties in triple-negative breast cancer (TNBC) cells. The cytotoxic effect of SANG was examined in MDA-MB-231 and MDA-MB-468 cell models at a low molecular level. In this study, SANG remarkably inhibited the inflammatory mediator chemokine CCL2 in MDA-MB-231 and MDA-MB-468 cells. Furthermore, qRT-PCR confirmed with Western analysis studies showed that mRNA CCL2 repression was concurrent with reducing its main regulator IKBKE and NF-κB signaling pathway proteins in both TNBC cell lines. The total ERK1/2 protein was inhibited in the more responsive MDA-MB-231 cells. SANG exhibited a higher potential to inhibit cell migration in MDA-MB-231 cells compared to MDA-MB-468 cells. Data obtained in this study suggest a unique antiangiogenic and antimetastatic effect of SANG in the MDA-MB-231 cell model. These effects are related to the compound’s ability to inhibit the angiogenic CCL2 and impact the ERK1/2 pathway. Therefore, SANG use may be recommended as a component of the therapeutic strategy for TNBC.

Abstract
Angiogenesis is the process of developing new blood vessels from pre-existing ones. This review summarizes the main features of physiological and pathological angiogenesis and those of angiogenesis activation and inhibition. In healthy adults, angiogenesis is absent apart from its involvement in female reproductive functions and tissue regeneration. Angiogenesis is a complex process regulated by the action of specific activators and inhibitors. In certain diseases, modulating the angiogenic balance can be a therapeutic route, either by inhibiting angiogenesis (for example in the case of tumor angiogenesis), or by trying to activate the process of new blood vessels formation, which is the goal in case of cardiac or peripheral ischemia.

Abstract
Angiogenesis is involved in physiological and pathological processes in the body. Tumor angiogenesis is a key factor associated with tumor growth, progression, and metastasis. Therefore, there is great interest in developing antiangiogenic strategies. Hypoxia is the basic initiating factor of tumor angiogenesis, which leads to the increase of vascular endothelial growth factor (VEGF), angiopoietin (Ang), hypoxia-inducible factor (HIF-1), etc. in hypoxic cells. The pathways of VEGF and Ang are considered to be critical steps in tumor angiogenesis. A number of antiangiogenic drugs targeting VEGF/VEGFR (VEGF receptor) or ANG/Tie2, or both, are currently being used for cancer treatment, or are still in various stages of clinical development or preclinical evaluation. This article aims to review the mechanisms of angiogenesis and tumor angiogenesis and to focus on new drugs and strategies for the treatment of antiangiogenesis. However, antitumor angiogenic drugs alone may not be sufficient to eradicate tumors. The molecular chaperone heat shock protein 90 (HSP90) is considered a promising molecular target. The VEGFR system and its downstream signaling molecules depend on the function of HSP90. This article also briefly introduces the role of HSP90 in angiogenesis and some HSP90 inhibitors.

Abstract
Digestive tumours, a common kind of malignancy worldwide, have recently led to the most tumour-related deaths. Angiogenesis, the process of forming novel blood vessels from pre-existing vessels, is involved in various physiological and pathological processes in the body. Many studies suggest that abnormal angiogenesis plays an important role in the growth, progression, and metastasis of digestive tumours. Therefore, anti-angiogenic therapy is considered a promising target for improving therapeutic efficacy. Traditional strategies such as bevacizumab and regorafenib can target and block the activity of proangiogenic factors to treat digestive tumours. However, due to resistance and some limitations, such as poor pharmacokinetics, their efficacy is not always satisfactory. In recent years, nanotechnology-based anti-angiogenic therapies have emerged as a new way to treat digestive tumours. Compared with commonly used drugs, nanoparticles show great potential in tumour targeted delivery, controlled drug release, prolonged cycle time, and increased drug bioavailability. Therefore, anti-angiogenic nanoparticles may be an effective complementary therapy to treat digestive tumours. In this review, we outline the different mechanisms of angiogenesis, the effects of nanoparticles on angiogenesis, and their biomedical applications in various kinds of digestive tumours. In addition, the opportunities and challenges are briefly discussed.

Abstract
Colorectal cancer (CRC) is a commonly diagnosed malignancy with unsatisfactory survival outcomes. Recent studies indicate that noncoding RNAs (ncRNAs) can be selectively packaged into exosomes, the extracellular vesicles composed of a lipid bilayer, and delivered from donor to recipient cells, thus regulating the behavior of the recipient cells. Increasing evidence has demonstrated that exosomal ncRNAs in blood exhibit distinct expression patterns among CRC patients with or without metastasis, and healthy controls. Moreover, exosomal ncRNAs can participate in the regulation of tumor microenvironment, the establishment of pre-metastatic niches, and the induction of drug resistance via cell-to-cell communication. Intriguingly, exosomal ncRNAs have the potential to serve as biomarkers for diagnosis, prognostic prediction, and therapeutic response monitoring of patients with CRC. In this review, we summarize the emerging functions of exosomal ncRNAs during CRC development and also discuss their potential clinical application in patients with CRC.

Abstract
When Folkman first suggested a theory about the association between angiogenesis and tumor growth in 1971, the hypothesis of targeting angiogenesis to treat cancer was formed. Since then, various studies conducted across the world have additionally confirmed the theory of Folkman, and numerous efforts have been made to explore the possibilities of curing cancer by targeting angiogenesis. Among them, anti-angiogenic gene therapy has received attention due to its apparent advantages. Although specific problems remain prior to cancer being fully curable using anti-angiogenic gene therapy, several methods have been explored, and progress has been made in pre-clinical and clinical settings over previous decades. The present review aimed to provide up-to-date information concerning tumor angiogenesis and gene delivery systems in anti-angiogenic gene therapy, with a focus on recent developments in the study and application of the most commonly studied and newly identified anti-angiogenic candidates for anti-angiogenesis gene therapy, including interleukin-12, angiostatin, endostatin, tumstatin, anti-angiogenic metargidin peptide and endoglin silencing.

Abstract
Peripheral arterial disease (PAD) is a debilitating complication of diabetes mellitus (DM) that leads to thousands of injuries, amputations, and deaths each year. The use of mesenchymal stem cells (MSCs) as a regenerative therapy holds the promise of regrowing injured vasculature, helping DM patients live healthier and longer lives. We report the use of muscle-derived MSCs to treat surgically-induced hindlimb ischemia in a mouse model of type 1 diabetes (DM-1). We serially evaluate several facets of the recovery process, including αVβ3-integrin expression (a marker of angiogenesis), blood perfusion, and muscle function. We also perform microarray transcriptomics experiments to characterize the gene expression states of the MSC-treated is- chemic tissues, and compare the results with those of non-ischemic tissues, as well as ischemic tissues from a saline-treated control group. The results show a multifaceted impact of mMSCs on hindlimb ischemia. We determined that the angiogenic activity one week after mMSC treatment was enhanced by approximately 80% relative to the saline group, which resulted in relative increases in blood perfusion and muscle strength of approximately 42% and 1.7-fold, respectively. At the transcriptomics level, we found that several classes of genes were affected by mMSC treatment. The mMSCs appeared to enhance both pro-angiogenic and metabolic genes, while suppressing anti-angiogenic genes and certain genes involved in the inflammatory response. All told, mMSC treatment appears to exert far-reaching effects on the microenvironment of ischemic tissue, enabling faster and more complete recovery from vascular occlusion.

Abstract
We investigated the antiangiogenic effects of Lindera obtusiloba Blume (Hwangmaemok, HMM), which is a plant in the Lauraceae family that is commonly used to treat colds and gastritis. Moreover, given that a recent study reported the inhibitory effects of HMM extract on cancer metastasis, we hypothesized that HMM extract might possess and antiangiogenic function. Thus, this study was conducted to investigate the effects of HMM extract on endothelial cell proliferation, migration, and neovascularization in chick chorioallantoic membrane (CAM), and investigated the molecular mechanism of antiangiogenesis using a ProteoChip-based proteomics technology. To examine the effects of HMM extracts on endothelial cell proliferation and migration, we conducted basic fibroblast growth factor (bFGF)-induced human umbilical vein endothelial cell (HUVEC) proliferation and migration. To assess the molecular mechanism of the antiangiogenic effects of HMM extract, a ProteoChip-based forwarded phase antibody array was employed to identify the differential expression of cell cycle proteins in HMM-treated HUVECs. HMM extract inhibited bFGF-induced HUVEC proliferation and migration in a dose-dependent manner and CAM angiogenesis. The ProteoChip-based antibody microarray data showed upregulation of Nibrin/NBS1 and downregulation of Plk-1 and Cyclin E, which are involved in cell division and controlling the cell cycle in bFGF-induced HUVECs. These data suggest that HMM may be a potent antitumor medicinal herb. The present study demonstrates that the antiangiogenic effect of HMM may be due to suppression of endothelial cell proliferation and migration. Taken together, these results emphasize the potential to use HMM extract as a potent angiogenesis inhibitor to treat cancer.

Abstract
Optic neuropathy is a neurodegenerative disease which involves optic nerve injury. It is caused by acute or intermittent insults leading to visual dysfunction. There are number of factors, responsible for optic neuropathy, and the optic nerve axon is affected in all type which causes the loss of retinal ganglion cells. In this review we will highlight various mechanisms involved in the cell loss cascades during axonal degeneration as well as ischemic optic neuropathy. These mechanisms include oxidative stress, excitotoxicity, angiogenesis, neuroinflammation and apoptosis following retinal ischemia. We will also discuss the effect of neuroprotective agents in attenuation of the negative effect of factors involve in the disease occurrence and progression.

Systemic investigation of the chemical constituents of M. alba fruits led to the identification of a novel oxolane derivative, (R*)-2-((2S*,3R*)-tetrahydro-2-hydroxy-2-methylfuran-3-yl)propanoic acid (1), namely, odisolane, along with five known heterocyclic compounds (2-6). The structure of the new compound was elucidated on the basis of HR-MS, 1D and 2D NMR ((1)H-(1)H COSY, HSQC, HMBC, and NOESY) data analysis. Compound 1 has a novel skeleton that consists of 8 carbon units with an oxolane ring, which until now has never been identified in natural products. The isolated compounds were subjected to several activity tests to verify their biological function. Among them, compounds 1, 3, and 5 significantly inhibited cord formation in HUVECs. The action mechanism of compound 3, which had the strongest antiangiogenic activity, was mediated by decreasing VEGF, p-Akt, and p-ERK protein expression. These results suggest that compounds isolated from M. alba fruits might be beneficial in antiangiogenesis therapy for cancer treatment.

Abstract
With the development of cell biology and microbiology, it has become easy to culture many types of animal cells and microbes, and they are frequently used for phenotypic screening to explore medicinal seeds. On the other hand, it is recognized that cells and pathogenic microbes present in pathologic sites and infected regions of the human body display unique properties different from those under general culture conditions. We isolated several bioactive compounds from marine medicinal resources using constructed bioassay-guided separation focusing on the unique changes in the characteristics of cells and pathogenic microbes (Mycobacterium spp.) in the human body under disease conditions. In addition, we also carried out identification studies of target molecules of the bioactive compounds by methods utilizing the gene expression profile, transformants of cells or microbes, synthetic probe molecules of the isolated compounds, etc., since bioactive compounds isolated from the phenotypic screening system often target new molecules. This review presents our phenotypic screening systems, isolation of bioactive compounds from marine medicinal resources, and target identification of bioactive compounds.

Abstract
Angiogenesis is a finely tuned process, which is the result of the equilibrium between pro- and antiangiogenic factors. In solid tumor angiogenesis, the balance is highly in favor of the production of new, but poorly functional blood vessels, initially intended to provide growing tumors with nutrients and oxygen. Among the numerous proteins involved in tumor development, several types of ion channels are overexpressed in tumor cells, as well as in stromal and endothelial cells. Ion channels thus actively participate in the different hallmarks of cancer, especially in tumor angiogenesis and metastasis. Indeed, from their strategic localization in the plasma membrane, ion channels are key operators of cell signaling, as they sense and respond to environmental changes. This review aims to decipher how ion channels of different families are intricately involved in the fundamental angiogenesis and metastasis hallmarks, which lead from a nascent tumor to systemic dissemination. An overview of the possible use of ion channels as therapeutic targets will also be given, showing that ion channel inhibitors or specific antibodies may provide effective tools, in the near future, in the treatment of carcinomas.

Abstract
CONTEXT Progression of cancer cells is completely dependent on its angiogenesis. Inhibition of tumor angiogenesis has shed new light on cancer treatment. As a result, anti-angiogenesis therapy represents one of the most significant advances in clinical oncology. Peganum harmala L. (Zygophyllaceae) is a native plant from the eastern Iranian region, which is used as a traditional folk medicine. Although some biological properties of this plant are determined, its effect on angiogenesis is still unclear. OBJECTIVE We investigated the anti-angiogenic effects of heat and low pH stable hydroalcoholic extract of P. harmala seeds on endothelial cells (ECs) proliferation and VEGF secretion. MATERIALS AND METHODS Dried Peganum seeds were purchased from Kermanshah Traditional Bazar in 2011. Hydroalcoholic extract of dried seeds (0, 10, 20, 40, 60, 80, 100, 120, and 150 μg/ml) was used for in vitro evaluation of its cytotoxicity, anti-proliferative, and anti-angiogenic effects on ECs. In vitro effect of the extract on VEGF secretion was assayed using ELISA. RESULTS Treatment with hydroalcoholic extract at seven different concentrations resulted in significant decrease of ECs proliferation and angiogenesis with an ID50 of ∼ 85 μg/ml. VEGF secretion was (inhibited) decreased by the extracts at concentrations higher than 10 μg/ml. DISCUSSION AND CONCLUSION Herbal plant extracts still attract attention owing to their fewer side effects comparing to synthetic drug agents. Current study indicated that hydroalcoholic extract of P. harmala seeds contains a potent anti-angiogenic component, which exerts its inhibitory effect mainly through down-regulation of essential mediators such as VEGF.

Abstract
Angiogenesis plays critical roles in human physiology that range from reproduction and fetal growth to wound healing and tissue repair. The sophisticated multistep process is tightly regulated in a spatial and temporal manner by "on-off switch signals" between angiogenic factors, extracellular matrix components, and endothelial cells. Uncontrolled angiogenesis may lead to several angiogenic disorders, including vascular insufficiency (myocardial or critical limb ischemia) and vascular overgrowth (hemangiomas, vascularized tumors, and retinopathies). Thus, numerous therapeutic opportunities can be envisaged through the successful understanding and subsequent manipulation of angiogenesis. Here, we review the clinical implications of angiogenesis and discuss pro- and antiangiogenic agents that offer potential therapy for cancer and other angiogenic diseases.

Abstract
Box-Behnken design criterion was applied to identify the significant effects of various extraction parameters such as temperature, time, and solvent-solid ratio on extraction of tea carbohydrate. Among the three variables tested extraction temperature, and solvent-solid ratio were found to have significant effect on tea carbohydrate extraction. The most suitable condition for extraction of tea carbohydrate was found to be a single step extraction at extraction temperature 90°C, extraction time 30 min, and solvent-solid ratio 5:1. At these optimum extraction parameters, the maximum yield of tea carbohydrate obtained experimentally was found to be very close to its predicted value of 3.47% dry weight of root. Then, we have studied the influence of tea carbohydrate on biochemical parameters in hepatocellular carcinoma (HCC) animals. Hepatocellular carcinoma was induced by the injection of 1×10(5) H22 hepatocarcinoma cells into right hind thigh muscle in experimental animals. Tea carbohydrate could inhibit tumour growth and decrease microvessel density in tumour tissue. The altered amount of serum white blood cells (WBC), Interferon-gamma (IFN-γ) and tumor necrosis factor-alpha (TNF-α) in HCC animals were dose-dependently increased, whereas activities of serum alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) were dose-dependently decreased in the drug treated animals. In addition, tea carbohydrate administration could decrease expression of vascular endothelial growth factor (VEGF) and proliferating cell nuclear antigen (PCNA) in H22 tumor tissue. It can be concluded that tea carbohydrate displayed strong antitumour activity in animals.

Abstract
Deltonin, a steroidal saponin, isolated from Dioscorea zingiberensis Wright (DZW), has shown high-cytotoxic activity in cancer cells. However, its mechanisms and in vivo anti-cancer effects remain unknown. In the present study, we evaluated the effects and explored the anti-tumor mechanisms of deltonin on a panel of colon cancer cell lines and in a mouse model of murine colon cancer C26. Deltonin had more cytotoxic effect on C26 cells than 5-fluorouracil had, promoting dramatic G2-M phase arrest and apoptosis in C26 cells in a concentration-dependent manner; oral administration of deltonin significantly inhibited the tumor growth and prolonged survival of the tumor bearing mice. The deltonin treatment caused a noticeable apoptosis in tumor tissue, which associated with increased levels of Bax, activated caspase-3, caspase-9, and cleaved poly (ADPribose) polymerase, decreased pro-caspase-8, pro-caspase-9, Bcl-2 expression levels and extracellular signal-regulated kinase-1/2 activity; and dose-dependently inhibit angiogenesis. In conclusion, the findings in this study demonstrated that deltonin is an effective natural agent for cancer therapy, which may be mediated, in part, by induction of apoptosis, as well as involve mitogen-activated protein kinase pathways, and inhibition of angiogenesis.

Abstract
Senegasaponins [senegin II (1), senegin III (2), senegin IV (3), senegasaponin a (4), and senegasaponin b (5)] from Polygala senega were re-discovered as selective anti-proliferative substances against human umbilical vein endothelial cells (HUVECs). Senegasaponins (1-5) showed anti-proliferative activity against HUVECs with IC(50) values in the range 0.6-6.2 μM, and the selective index was 7-100-fold in comparison with those for several cancer cell lines, while the desacyl mixture of senegasaponins (6) and tenuifolin (7) lost anti-proliferative activity, indicating that the 28-O-glycoside moiety and methoxycinnamoyl group were essential for the HUVEC-selective growth inhibition of senegasaponins. Senegin III (2) inhibited the vascular endothelial growth factor (VEGF)-induced in vitro tubular formation of HUVECs and basic fibroblast growth factor (bFGF)-induced in vivo neovascularization in the mouse Matrigel plug assay. Moreover, senegin III (2) suppressed tumor growth in the ddY mice s.c.-inoculated murine sarcoma S180 cells. The analysis of the action mechanism of senegin III (2) suggested that the induction of pigment epithelium-derived factor (PEDF) would contribute to the anti-angiogenic effects of senegasaponins.

Abstract
The immunization approaches with DNA vaccine priming and subsequent protein or peptide boosting has been widely tested in various models of infectious diseases. However, these approaches are seldom reported in the areas of cancer immunotherapy. In this study we combined endoglin plasmid DNA and recombinant protein as vaccines and used them to prime and boost, simultaneously, as a vaccine strategy. Our results showed that combination of endoglin DNA and protein vaccines could enhance both protective and therapeutic anti-tumor efficacy in both colon carcinoma and Lewis lung carcinoma models. Significant inhibition of tumor angiogenesis was found in the tumor tissues. The titers of autoantibodies against murine endoglin were significantly increased and the antibody levels lasted longer in the mice with combined endoglin DNA and recombinant protein vaccination. CTL response against endoglin-positive HUVECs, but not against endoglin-negative tumor cells was found in the mice combined DNA with protein vaccination. In addition, combination of endoglin DNA and recombinant protein vaccination significantly induced IFN-gamma secreting cells. These observations suggested that a combination of endoglin DNA and recombinant protein immunization as a vaccine strategy was superior to those using endoglin DNA or recombinant protein alone as vaccines.

Abstract
1. Angiogenesis, the formation of new capillaries from existing vasculature, is a critical process in normal physiology as well as several physiopathologies. A desire to curb the supportive role angiogenesis plays in the development and metastasis of cancers has driven exploration into anti-angiogenic strategies as cancer therapeutics. Key to this, angiogenesis additionally displays an exquisite sensitivity to bioavailable copper. Depletion of copper has been shown to inhibit angiogenesis in a wide variety of cancer cell and xenograft systems. Several clinical trials using copper chelation as either an adjuvant or primary therapy have been conducted. Yet, the biological basis for the sensitivity of angiogenesis remains unclear. Numerous molecules important to angiogenesis regulation have been shown to be either directly or indirectly influenced by copper, yet a clear probative answer to the connection remains elusive. 2. Measurements of copper in biological systems have historically relied on techniques that, although demonstrably powerful, provide little or no information as to the spatial distribution of metals in a cellular context. Therefore, several new approaches have been developed to image copper in a biological context. One such approach relies on synchrotron-derived X-rays from third-generation synchrotrons and the technique of high resolution X-ray fluorescence microprobe (XFM) analysis. 3. Recent applications of XFM approaches to the role of copper in regulating angiogenesis have provided unique insight into the connection between copper and cellular behaviour. Using XFM, copper has been shown to be highly spatially regulated, as it is translocated from perinuclear areas of the cell towards the tips of extending filopodia and across the cell membrane into the extracellular space during angiogenic processes. Such findings may explain the heightened sensitivity of this cellular process to this transition metal and set a new paradigm for the kinds of regulatory roles that the spatial dynamics of cellular transition metals may play.

Abstract
The biological effects of the neuropeptide somatostatin (SST) are mediated via a family of five somatostatin receptors (SSTRs) belonging to a family of G-protein-coupled receptors (GPCRs). SSTR regulate the secretion of hormones, growth factors, neurotransmission and cell growth in receptor-specific manner. In addition, SST plays an inhibitory role in several mammary cancer models. These effects are mediated both indirectly through inhibition of hormones and growth factors which promote tumor growth as well as directly via SSTRs present on tumor cells to inhibit mitogenic signaling of growth factor receptor kinases leading to growth arrest and induction of apoptosis. Here, we present an overview on the role of SST and its analogs in breast cancer.

Abstract
In our continuing effort to expand the SAR of the quinoline domain of dihydropyrrolopyrazole series, we have discovered compound 15d, which demonstrated the antitumor efficacy with oral bioavailability. This effort also demonstrated that the PK/PD in vivo target inhibition paradigm is an effective approach to assess potential for antitumor efficacy. The dihydropyrrolopyrazole inhibitor 15d (LY2109761) is representative of a novel series of antitumor agents.

Abstract
OPINION STATEMENT Successful inhibition of angiogenesis with the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab has improved the efficacy seen with standard cytotoxic therapy in NSCLC. The addition of bevacizumab to first-line chemotherapy improved response rate and progression free survival and added 2 months to median overall survival for those patients with advanced stage NSCLC on the treatment arm of E4599. Bevacizumab is now a standard agent to add to frontline carboplatin and paclitaxel for patients with newly diagnosed NSCLC who meet the eligibility criteria from the landmark E4599 trial. Unfortunately about half of all patients are not eligible either because they have squamous histology, brain metastases, or are on anti-coagulation. Ongoing trials are further exploring the safety of bevacizumab in these patient populations, as well as in combination with other cytotoxic regimens. Exploration of other applications of bevacizumab in the second-line and adjuvant setting are ongoing as well. The largest class of drugs that block angiogenesis are the multi-targeted tyrosine kinase inhibitors (TKIs) that target the VEGF receptor (VEGFR). These drugs are still in development, and though two are now on the market for treating other malignancies, their role in NSCLC is under investigation. These agents have the advantages of hitting multiple targets, convenient oral administration, and potential for lower cost. Their lack of target specificity leads to unexpected toxicity, but also promising efficacy. For example, the overall objective response rate of 9.5% with single agent sunitinib compares similarly to that of pemetrexed or docetaxel in previously treated NSCLC patients, but toxicity, notably fatigue, lead to discontinuation in 38% of patients. Hypertension, hemorrhage and cavitation are common toxicities amongst this class of agents. Rash, fatigue, myalgia, and hand-foot syndrome are more specifically seen with TKIs. These compounds may also be synergistic or additive with traditional cytotoxic chemotherapy drugs and other novel compounds. In early trials sorafenib as a single agent has shown no clinical response in previously treated NSCLC patients, whereas clinical benefit in combination with erlotinib or chemotherapy has been seen in early studies. Vandetanib has demonstrated objective responses as a single agent and in combination with chemotherapy in previously treated NSCLC patients. A phase I trial of AZD2171 with carboplatin and paclitaxel in newly diagnosed advanced stage NSCLC also demonstrated promising results with 6 of 15 patients achieving partial responses. NSCLC specific trials are also underway, or in development for pazopanib, axitinib, AMG 706, XL647, enzastaurin, and other TKIs. Other anti-angiogenesis agents with different mechanisms of action include thalidomide and its derivatives, monoclonal antibodies to the VEGFRs, and VEGF Trap, a chimeric molecule which combines extracellular portions of VEGFR1 and VEGFR2 with the Fc portion of immunoglobulin G1 to form a molecule that binds and "traps" VEGF. Despite modest improvements, prognosis continues to be poor for patients with advanced NSCLC. Bevacizumab is a first step into the world of angiogenesis inhibitors for NSCLC and though it only offers a modest survival benefit in a limited patient population, it paves the way for the development of the next generation of anti-angiogenesis inhibitors. We can hope that further improvements in survival will follow.

Abstract
Fibroblast growth factor receptor-1 (FGFR-1) has been used as a target for anti-angiogeneic therapy of cancer. The strategies of combining anti-angiogenic biotherapy with chemotherapeutic drugs show potential and promise for cancer therapy. In this study, we evaluated the anti-tumour efficacy of chicken FGFR-1 (cFR-1) vaccine combined with low-dose gemcitabine in two mice tumour models. We found that both the cFR-1 vaccine and low-dose gemcitabine can suppress tumour growth to some extent. Remarkably, the combination strategy produces an apparent decrease in tumour volume, microvessel density and tumour cell proliferation, and an increase of apoptosis without obvious side-effects compared with either therapy alone. Moreover, the combination strategy also demonstrated synergistic indices against tumour growth and angiogenesis. Furthermore, auto-antibodies against mouse FGFR-1 were identified. These findings support the idea that the combination strategy synergistically strengthens anti-tumour activity via suppression of tumour angiogenesis without overt toxicity in tumour-bearing mice.

Abstract
AIM: To evaluate whether the combination of recom-binant chicken fibroblast growth factor receptor -1 (FGFR-1) protein vaccine (cFR-1) combined with low-dose gemcitabine would improve anti-tumor efficacy in a mouse CT26 colon adenocarcinoma (CT26) model.
METHODS: The CT26 model was established in BABL/c mice. Seven days after tumor cell injection, mice were randomly divided into four groups: combination therapy, cFR-1 alone, gemcitabine alone, and normal saline groups. Tumor growth, survival rate of tumor-bearing mice, and systemic toxicity were observed. The presence of anti-tumor auto-antibodies was detected by Western blot analysis and enzyme-linked immunospot assay, microvessel density (MVD) of the tumors and tumor cell proliferation were detected by Immunohistochemistry staining, and tumor cell apoptosis was detected by TdT-mediated biotinylated-dUTP nick end label staining.
RESULTS: The combination therapy results in apparent decreases in tumor volume, microvessel density and tumor cell proliferation, and an increase in apoptosis without obvious side-effects as compared with either therapy alone or normal control groups. Also, both auto-antibodies and the antibody-producing B cells against mouse FGFR-1 were detected in mice immunized with cFR-1 vaccine alone or with combination therapy, but not in non-immunized mice. In addition, the deposition of auto-antibodies on endothelial cells from mice immunized with cFR-1 was observed by immunofluorescent stain-ing, but not on endothelial cells from control groups. Synergistic indexes of tumor volume, MVD, cell apoptosis and proliferation in the combination therapy group were 1.71 vs 1.15 vs 1.11 and 1.04, respectively, 31 d after tumor cell injection.
CONCLUSION: The combination of cFR-1-mediated anti-angiogenesis and low-dose gemcitabine synergistically enhances the anti-tumor activity without overt toxicity in mice.

Abstract
Psoriasis is a chronic skin disease, characterized by epidermal hyperplasia, inflammation, angiogenesis and vascular remodelling. An immunohistochemical study on fifteen cryosections of psoriatic skin was performed using antibodies against VEGF, HIF1-alpha, CD34, Factor VIII, MMP-2, MMP-9, TIMP-1 and TIMP-2. Psoriatic skin showed a diffuse VEGF positive staining (13.15+/-6.6), while no expression was observed in normal epidermis. No or faint HIF-1alpha immunostaining was detected in healthy skin, while in psoriatic skin HIF-1alpha was diffusely expressed. A positive correlation between HIF-1alpha and VEGF was reported in psoriatic skin (r= 0.644; p=0.010). In psoriatic sections CD34 expression was significantly higher in respect to control skin (19.15+/-12.61 vs 3.0+/-0.23; p= 0.04), factor VIII immunostaining also demonstrated a significant increased development of the microvasculature in comparison with healthy skin (18.39+/-8.16 vs 7.4+/-0.20; p= 0.033). Total MMP-2 expression of healthy skin (30+/-2.26) was significantly lower in respect to the MMP-2 psoriatic skin (71.5+/-4.13; p= 0.0001) and a positive correlation was observed between VEGF and MMP-2 in psoriatic patients (r= 0.688; p= 0.046). In psoriatic skin MMP-9 expression was significantly increased in comparison to control skin (31+/-3.3 vs 8+/-6.1; p=0.007). All cases of psoriatic skin tissue showed that TIMP-2 and TIMP-1 expression statistically decreased in psoriatic skin (respectively 11+/-1.2 and 12+/-1.5) in comparison with healthy skin (respectively 15+/-3.2 and 53+/-3.8; p=0.0001). In conclusion, we observed that VEGF overexpression correlated with HIF-1alpha and MMP-2 expression, underlining the role of VEGF in psoriasis as a key factor in the link between inflammation and angiogenesis.

Abstract
Despite myriad advances, cardiovascular-related diseases continue to remain our greatest health problem. In more than half of patients with atherosclerotic disease, their first presentation to medical attention becomes their last. Patients often survive their first cardiac event through acute revascularization and placement of drug-eluting stents (DES), but only select coronary lesions are amenable to DES placement, resulting in the use of bare metal or no stent, both of which lack the benefit of antirestenotic therapy. In other patients, transient ischemic attacks (TIAs) and stroke constitute the initial presentation of disease. In these patients, the diagnostic and therapeutic options are woefully inadequate. Nanomedicine offers options to each of these challenges. Antiangiogenic paramagnetic nanoparticles may be used to serially assess the severity of atherosclerotic disease in asymptomatic, high-risk patients by detecting the development of plaque neovasculature, which reflects the underlying lesion activity and vulnerability to rupture. The nanoparticles can locally deliver antiangiogenic therapy, which may acutely retard plaque progression, allowing aggressive statin therapy to become effective. Moreover, these agents may be useful as a quantitative marker to guide atherosclerotic management in an asymptomatic patient. In those cases proceeding to the catheterization laboratory for revascularization, nanoparticles incorporating antirestenotic drugs can be delivered directly into the wall of lesions not amenable to DES placement. Targeted nanoparticles could help ensure that antirestenotic drugs are available for all lesions. Moreover, displacement of antiproliferative agents from the intimal surface into the vascular wall is likely to improve rehealing of the endothelium, improving postprocedural management of these patients.

Abstract
Vatalanib (PTK787/ZK-222584) is a new oral antiangiogenic molecule that inhibits all known vascular endothelial growth factor receptors. Vatalanib is under investigation for the treatment of solid tumors. Disposition and biotransformation of vatalanib were studied in an open-label, single-center study in patients with advanced cancer. Seven patients were given a single oral (14)C-radiolabeled dose of 1,000 mg of vatalanib administered at steady state, obtained after 14 consecutive daily oral doses of 1,000 mg of nonradiolabeled vatalanib. Plasma, urine, and feces were analyzed for radioactivity, vatalanib, and its metabolites. Metabolite patterns were determined by high-performance liquid chromatography coupled to radioactivity detection with off-line microplate solid scintillation counting and characterized by LC-MS. Vatalanib was well tolerated. The majority of adverse effects corresponded to common toxicity criteria grade 1 or 2. Two patients had stable disease for at least 7 months. Plasma C(max) values of (14)C radioactivity (38.3 +/- 26.0 microM; mean +/- S.D., n = 7) and vatalanib (15.8 +/- 9.5 microM) were reached after 2 and 1.5 h (median), respectively, indicating rapid onset of absorption. Terminal elimination half-lives in plasma were 23.4 +/- 5.5 h for (14)C radioactivity and 4.6 +/- 1.1 h for vatalanib. Vatalanib cleared mainly through oxidative metabolism. Two pharmacologically inactive metabolites, CGP-84368/ZK-260120 [(4-chlorophenyl)-[4-(1-oxy-pyridin-4-yl-methyl)-phthalazin-1-yl]-amine] and NVP-AAW378/ZK-261557 [rac-4-[(4-chloro-phenyl)amino]-alpha-(1-oxido-4-pyridyl)phthalazine-1-methanol], having systemic exposure comparable to that of vatalanib, contributed mainly to the total systemic exposure. Vatalanib and its metabolites were excreted rapidly and mainly via the biliary-fecal route. Excretion of radioactivity was largely complete, with a radiocarbon recovery between 67% and 96% of dose within 7 days (42-74% in feces, 13-29% in urine).

Abstract
Aberrant angiogenesis is an essential step for the progression of solid tumors. Thus anti-angiogenic therapy is one of the most promising approaches to control tumor growth. In this study, we examined the ability of 20(R)-ginsenoside Rg3 (Rg3), one of the active compounds present in ginseng root, to interfere with the various steps of angiogenesis. Rg3 was found to inhibit the proliferation of human umbilical vein endothelial cells (HUVEC) with an IC50 of 10 nM in Trypan blue exclusion assay. Rg3 (1-10(3) nM) also dose dependently suppressed the capillary tube formation of HUVEC on the Matrigel in the presence or absence of 20 ng/ml vascular endothelial growth factor (VEGF). The VEGF-induced chemoinvasion of HUVEC and ex vivo microvascular sprouting in rat aortic ring assay were both significantly attenuated by Rg3. In addition, Rg3 (150 and 600 nM) remarkably abolished the basic fibroblast growth factor (bFGF)-induced angiogenesis in an in vivo Matrigel plug assay. The Matrix metalloproteinases (MMPs), such as MMP-2 and MMP-9, which play an important role in the degradation of basement membrane in angiogenesis and tumor metastasis present in the culture supernatant of Rg3-treated aortic ring culture were found to decrease in their gelatinolytic activities. Taken together, these data underpin the anti-tumor property of Rg3 through its angiosuppressive activity.

Abstract
Transfection of the antiangiogenic angiostatin and endostatin genes was shown to be an alternative to high-dose administration of angiostatin or endostatin proteins for cancer therapy. We have systematically investigated whether coadministration of the mouse angiostatin kringle 1-3 gene (pFLAG-AngioK1/3) and the endostatin gene (pFLAG-Endo) complexed with cationic liposomes exhibits enhanced therapeutic efficacy. In vitro, the coexpressed mixture of angiostatin K1-3 and endostatin more effectively reduced angiogenesis in chorioallantoic membranes than either angiostatin K1-3 or endostatin alone. In vivo, subcutaneous co-administration of pFLAG-AngioK1/3 and pFLAG-Endo lipoplexes more effectively inhibited vascularization in Matrigel plugs implanted in mice than either one alone. Additionally, subcutaneous administration of these genes inhibited the growth and formation of pulmonary metastases of B16BL6 melanoma cells in mice. Compared to treatment with an empty vector, treatment with pFLAG-AngioK1/3 plus pFLAG-Endo inhibited 81% of tumor growth, while treatment with pFLAG-AngioK1/3 or pFLAG-Endo inhibited tumor growth 70 and 69%, respectively. Cotreatment with the two plasmids after primary tumor excision induced a 90% inhibition of pulmonary metastases versus 79% for pFLAG-AngioK1/3 or 80% for pFLAG-Endo individually. These results suggest that combined administration of angiostatin K1-3 and endostatin genes complexed with cationic liposomes may be an innovated antiangiogenic strategy for cancer therapy.

Abstract
Angiogenesis is crucial to tumor growth and metastasis, and interruption of this process is a prime avenue for therapeutic intervention of tumor proliferation. The present study has made use of the S180 tumor-bearing mouse model to investigate the polysaccharopeptide, PSP, isolated from the edible mushroom Coriolus versicolor, a herbal medicine known for its anti-angiogenesis properties. Quantitative analysis of microcorrosion casting of the tumor tissue showed more angiogenic features such as dense sinusoids and hot spots, in control (untreated) than in PSP-treated animals. Immunostaining of tumor tissues with antibody against the endothelial cell marker (Factor VIII) demonstrated a positive correlation in that both the vascular density and tumor weight were lower in mice treated with PSP. Morphometric analysis of corrosion casts revealed that, even though the total amount of new vessel production was reduced, the basic tumor type-specific vascular architecture was retained. However, the expression of vascular endothelial cell growth factor (VEGF) in these tumors was suppressed. In conclusion, anti-angiogenesis should be one of the pathways through which PSP mediated its anti-tumor activity.

Abstract
This study evaluated the anti-angiogenic activities of erianin in vivo and in vitro. Erianin, a natural product from Dendrobium chrysotoxum, caused moderate growth delay in xenografted human hepatoma Bel7402 and melanoma A375 and induced significant vascular shutdown within 4 h of administering 100 mg/kg of the drug. Erianin also displayed potent anti-angiogenic activities in vitro: it abrogated spontaneous or basic fibroblast growth factor-induced neovascularisation in chick embryo; it inhibited proliferation of human umbilical vein endothelial cells (EC(50) 34.1+/-12.7 nM), disrupted endothelial tube formation, and abolished migration across collagen and adhesion to fibronectin. Erianin also exerted selective inhibition toward endothelial cells, and quiescent endothelium showed more resistance than in proliferative and tumour conditions. In a cytoskeletal study, erianin depolymerised both F-actin and beta-tubulin, more significantly in proliferating endothelial cells than in confluent cells. In conclusion, erianin caused extensive tumour necrosis, growth delay and rapid vascular shutdown in hepatoma and melanoma models; it inhibited angiogenesis in vivo and in vitro and induced endothelial cytoskeletal disorganisation. These findings suggest that erianin has the therapeutic potential to inhibit angiogenesis in vivo and in vitro.

Abstract
Angiogenesis, or the growth of new blood vessels, has, in recent years, become an area of intense scientific research. The primary reason for this has been the realization that angiogenesis plays a key role in many common pathologies, and that its inhibition could have profound implications in the treatment of these disorders. A substantial number of anti-angiogenic agents have now been identified; however, none has, as of yet, achieved widespread acceptance in the clinic. Many agents have been identified as the result of clearly defined research programs, such as the inhibitors of the vascular endothelial growth factor transmembrane tyrosine kinase receptors, but many other simply by screening. The purpose of this article is to review the wealth of information available on known anti-angiogenic agents and to assess their future potential.
