[Cloning and antitumor activity of angiogenesis inhibitor HIAF-1].

OBJECTIVE: A new angiogenesis inhibitor HIAF-1 (human inhibitor angiogenesis factor-1) was cloned, expressed in E. coli and its antitumor activity was studied. METHODS: HIAF-1 was amplified by RT-PCR from human fetal liver tissue, then cloned into pET30a(+) vector and expressed in E. coli BL21:DE3 after sequencing. In vitro endothelial proliferation inhibiting activity of HIAF-1 was examined by MTT method. In vivo antitumor activity was studied in a murine model of IVTA2MA-891. RESULTS: HIAF-1 was first cloned from human fetal liver tissue. Sequence analysis of the inhibitor revealed identity to a c-terminal fragment of human collagen XVIII. HIAF-1 was effectively expressed in E. coli with a yield of 88 mg/L. Recombinant HIAF-1 protein could inhibit endothelial cell proliferation in vitro with an IC50 value of 7.5 micrograms/ml. In vivo studies showed that HIAF-1 inhibited growth rate of the primary tumor by 46.6% and metastasis by 68.9%. CONCLUSION: The cloned and the bio-engineering product of HIAF-1 is an angiogenesis inhibitor, capable of inhibiting tumor growth and metastasis.

Update on angiogenesis inhibitors.

PURPOSE OF REVIEW: A number of therapeutic agents have been developed which have anti-angiogenic potential. Here we present the most recent data from clinical trials with some of the promising inhibitors of angiogenesis. RECENT FINDINGS: Agents that target the vascular endothelial growth factor signaling pathway are the furthest along in clinical development. The last year has brought US Food and Drug Administration approval of bevacizumab (Avastin), a recombinant humanized anti-vascular endothelial growth factor monoclonal antibody. Bevacizumab has demonstrated a survival advantage in combination with chemotherapy for patients with metastatic colorectal cancer. Other agents with early promising results include PTK787/ZK 222584 (Vatalanib), ZD6474, and BAY 43-9006 (Sorafenib). SUMMARY: Angiogenesis inhibitors show promise, but evaluation for optimal efficacy has been a problem, given that the mechanisms of action of these agents differ from conventional cytotoxic agents and surrogate markers for inhibition of angiogenesis are not available.

[Inhibition of growth and metastases of human colon cancer xenograft in nude mice by angiogenesis inhibitor endostatin].

BACKGROUND & OBJECTIVE: Tumor angiogenesis is essential for growth and metastases of colon cancer. Angiogenesis inhibitors can induce apoptosis in colon cancer by inhibiting tumor angiogenesis and has strong inhibitory effect both on tumor growth and metastases of human colon cancer. Anti-angiogenic cancer therapy is important for selecting the timing and method of operation and program of complex treatment and enhancing the five-year survival rate of patients with colon cancer. In this study, we aimed to investigate the effects of angiogenesis inhibitor endostatin on the growth and metastases of colon cancer in vivo. METHODS: Metastatic model simulating human colon cancer was established by orthotopic implantation of histologically intact human tumor tissue into colon wall of nude mice. Endostatin was administered s.c. at dose of 0 mg/kg, 5 mg/kg, 10 mg/kg and 20 mg/kg, every day for six weeks. Seven weeks after implantation, the tumor weight and inhibition rates and intratumoral microvessel density (MVD) and apoptotic index (AI) and the presence of metastases are evaluated respectively after the mice were sacrificed. RESULTS: In compared with the untreated controls, growth of the orthotopically implanted tumor was significantly reduced in weight in mice treated with endostatin with an inhibition rate of 0%, 67.9%, 84.0%, and 90.1% at the dosage of 0 mg/kg, 5 mg/kg, 10 mg/kg, and 20 mg/kg, respectively. The MVD also decreased significantly in the treated mice [(12.8 +/- 4.1) versus (5.9 +/- 2.5), (2.2 +/- 1.4) and (0.74 +/- 0.3)]. The AI increased significantly in the treated mice [(3.87 +/- 2.61)%, versus (6.89 +/- 5.18%), (13.24 +/- 4.76)% and (20.97 +/- 9.04)%]. The incidences of peritoneal metastases were also significantly inhibited in the treated mice (90.0% versus 36.4%, 25.0%, and 0%). The incidences of liver metastases were also significantly inhibited in the treated mice (80.0% versus 27.3%, 16.7% and 0%). Tumor metastases to the liver and peritoneaum were also significantly inhibited in a dose-dependent manner (P < 0.05). CONCLUSIONS: Angiogenesis inhibitor endostatin can induce apoptosis in colon cancer by inhibiting tumor angiogenesis and has strong inhibitory effect both on tumor growth and metastases of human colon cancer xenograft in nude mice.

Heparin-steroid conjugates: new angiogenesis inhibitors with antitumor activity in mice.

Inhibitors of angiogenesis hold potential in the treatment of cancer and other diseases where the disease is caused or maintained by the inappropriate growth of blood vessels. In the present study, a novel inhibitor of angiogenesis was synthesized by covalently linking a nonanticoagulating derivative of heparin, heparin adipic hydrazide (HAH), by an acid-labile bond to the antiangiogenic steroid, cortisol. The rationale was that the heparin derivative, which binds to sulfated polyanion receptors on endothelial cells, should concentrate the steroid on the surface of vascular endothelial cells. Endocytosis of the conjugate and decomposition of the acid-labile linkage inside lysosomes and other acidic intracellular compartments should then lead to release of the cortisol and expression of its antiproliferative activity. Analysis of the stability of HAH-cortisol showed that it was stable at pH 7.4 and broke down rapidly (t1/2 15 min) at pH 4.8 at 37 degrees C. Treatment of murine pulmonary capillary endothelial cells with HAH-cortisol at 10(-5) M (with respect to cortisol) suppressed their DNA synthesis by 50% and inhibited their migration into wounded areas of confluent monolayers. HAH-cortisol at 10(-4) M (with respect to cortisol) did not suppress the DNA synthesis of Lewis lung carcinoma cells. Daily i.p. injections of HAH-cortisol into mice bearing s.c. sponge implants retarded vascularization of the sponge, and injections directly into the sponge abolished vascularization for as long as the injections were continued. Daily i.v. injections of HAH-cortisol at doses causing no apparent toxicity retarded the growth of solid s.c. Lewis lung carcinomas in mice by up to 65%. In all of these assays, equivalent treatments with a mixture of the HAH plus cortisol was significantly less effective. The antiproliferative effect of HAH-cortisol on endothelial cells appeared independent of the glucocorticoid activity of the steroid since HAH conjugated to 5 beta-pregnane-3 alpha,17 alpha,21-triol-20-one, a steroid lacking glucocorticoid or mineralocorticoid activity, was even more effective at inhibiting DNA synthesis by murine pulmonary capillary endothelial cells than was HAH-cortisol. In conclusion, HAH-cortisol represents the prototype of a new class of angiogenesis inhibitors for the treatment of cancer and other angiogenic diseases.

Critical components of the female reproductive pathway are suppressed by the angiogenesis inhibitor AGM-1470.

Angiogenesis, the growth of new blood vessels, occurs normally in female reproductive organs. We tested the hypothesis that angiogenesis inhibition may affect fertility by studying the reproductive system in either pregnant or nonpregnant cycling mice after treatment with the angiogenesis inhibitor AGM-1470. Administration of AGM-1470 to pregnant mice resulted in complete failure of embryonic growth due to interference with decidualization, placental and yolk sac formation, and embryonic vascular development. When nonpregnant cycling female mice were chronically treated with AGM-1470, inhibition of endometrial maturation and corpora lutea was observed. These data suggest that processes in reproduction can be controlled through angiogenesis inhibition.

[Novel angiogenesis inhibitors for molecular target therapy of cancer].

Angiogenesis, neovascularization from pre-existing vasculature, is essential to allow growth of primary solid tumors and to enable metastasis. Recent biological studies in both tumor and endothelial cells have begun to present a wide variety of molecular targets for developing angiogenesis inhibitors. Therefore, angiogenesis inhibitors including anti-angiogenic agents as well as anti-vascular targeting agents have become promising drugs in cancer chemotherapy. However current unsolved problems in anti-angiogenic therapy are the lack of surrogate markers for therapeutic efficacy, as well as of establishment of effective combinations with other therapeutic approaches including conventional anticancer therapy, radiotherapy, and immunotherapy. This article focuses on the promising drugs with anti-angiogenic activity and their molecular targets under clinical trials, as well as the significance of clinical evaluation for anti-angiogenic therapies.

Modulation of T lymphocyte function by the angiogenesis inhibitor AGM-1470.

The angiogenesis inhibitor AGM-1470 has recently been reported to inhibit collagen-induced arthritis in rats. To determine if the anti-arthritic effects of AGM-1470 might be due to T cell inhibition, we have studied its effects on T cell responses in vitro. Responses of human cells to tetanus toxoid (TT), and those of murine splenocytes to staphylococcal enterotoxin (SE), mitogens or a mls difference were inhibited by AGM-1470. Responses of human cells to SE, OKT3 and PHA were all partially inhibited on day 2 (d2) but not d3, and in fact were augmented on d6-8. The amount of IL-2 in SEA cultures was augmented on d4 and d5. There were no differences in the expression of CD3, CD4, CD8, CD25, CD45RA, CD45RO, LFA-1, VLA-4 or VLA-6 in inhibited cultures, except for slight decreases in CD25 and CD45RO in TT cultures. These results indicated that the angiogenesis inhibitor AGM-1470 also modulates human and murine lymphocyte function.

Angiogenesis inhibitors in lung cancer.

Lung cancer is a major public health problem and the leading cause of cancer-related death worldwide. Its survival rates have changed little over the past 20 years. The best clinical benefit (ie, survival rates) with combination cytotoxic therapies in non-small-cell lung cancer (NSCLC) may have been reached. The need for improved survival rates in NSCLC has driven the development of novel, rationally designed, targeted therapies. Inhibitors of angiogenesis have been developed and are increasingly studied. Potential targets for therapy include inhibitors of vascular endothelial growth factor receptor, endogenous angiogenesis inhibitors, and cyclooxygenase inhibitors. Combining targeted molecules with traditional cytotoxic therapies usually results in lower required chemotherapy doses and fewer, less severe side effects. A number of ongoing randomized studies are underway to evaluate this idea. It is anticipated that these new targeted therapies will play an important role, along with cytotoxic and radiation therapies, in the management of metastatic disease.

Chondromodulin-I and tenomodulin: a new class of tissue-specific angiogenesis inhibitors found in hypovascular connective tissues.

In tissues and/or organs of mesenchymal origin, the vasculature is usually well developed. However, there are certain hypovascular tissues that exhibit powerful anti-angiogenic resistance, implying the presence of tissue-type specific inhibitors of angiogenesis. Hyaline cartilage is one example, and several anti-angiogenic factors have been purified from cartilage. We previously identified chondromodulin-I (ChM-I) as a tissue-specific inhibitor of angiogenesis in fetal bovine cartilage. ChM-I is specifically expressed in the avascular regions of the growth-plate and cartilaginous bone rudiments in embryos. Recently, we cloned a novel type II transmembrane protein, tenomodulin (TeM), having a domain homologous to ChM-I at its C-terminus. TeM turned out to be expressed specifically in other hypovascular structures in the mesenchyme, such as the epimysium, tendon, and ligaments. In this overview, we discuss the structural characteristics of this class of anti-angiogenic molecules and their pathophysiological role in the control of vascularity.

The characterization of angiogenesis inhibitor from shark cartilage.

An angiogenesis inhibitor isolated from shark cartilage, SCF2, has been characterized. SCF2 was shown to have specific angiogenesis-inhibiting activity in endothelial cell culture assays. Results of structural and functional studies indicate that the inhibitor is not a typical protein. It is a heat-stable proteoglycan, which contains keratan sulfate units and peptide. Gel filtration chromatography shows that the molecular weight of the angiogenesis inhibitor is about 10 kd.

Angiogenesis inhibitors: a new class of drugs.

Angiogenesis inhibitors belong to a new class of drugs. Many of these drugs are in clinical trials to treat cancer, while others have recently received FDA approval. However, angiogenesis inhibitors operate by different mechanisms than conventional cytotoxic chemotherapies, and require different guidelines for their optimum use in animal models and in humans. Some of the more significant guidelines of antiangiogenic therapy are assembled in this chapter, and their scientific basis is discussed.

Pharmacodynamic-mediated reduction of temozolomide tumor concentrations by the angiogenesis inhibitor TNP-470.

The angiogenic phenotype is associated with increased tumor neovascularization and a state of vascular hyperpermeability to macromolecules. Angiogenesis inhibitors could reverse these processes, resulting in tumor capillaries that have normal membrane permeability. It was proposed that the switch from a hyperpermeable to a normal permeable state could have the untoward effect of decreasing tumor concentrations of anticancer drugs coadministered with angiogenesis inhibitors. The current investigation evaluated a potential drug interaction between the angiogenesis inhibitor O-(N-chloroacetyl-carbamoyl)-fumagillol (TNP-470) and the alkylating agent temozolomide (TMZ), in xenograft models that differentially expressed vascular endothelial growth factor (VEGF), a driving force for angiogenesis. Nude rats bearing either s.c. low VEGF (V-) or high VEGF (V+) or intracerebral V+ gliomas were administered either a multiple-dose regimen of TNP-470 or vehicle control. One day after the last dose of vehicle or TNP-470, a steady-state dosing regimen of TMZ was administered with subsequent collection and high-performance liquid chromatography analysis of plasma and either tumor homogenate or tumor microdialysis steady-state TMZ concentrations, and in some cases [5-(3-methyltriazen-1-yl)imidazole-4-carboximide] MTIC, its active metabolite. Microvessel density (MVD) was quantitated by image analysis using an anti-CD31 method. Statistical analyses of pharmacokinetic and pharmacodynamic end points in the control and TNP-470 treatment groups were completed by nonparametric tests. In both the s.c. and intracerebral V+ models, TNP-470 treatment produced significant reductions in TMZ tumor concentrations and tumor:plasma concentration ratios compared with control, being reduced an average of 25% and 50% in the s.c. and intracerebral tumors, respectively. MTIC concentrations in V+ s.c. tumors also were reduced by 50% in the presence of TNP-470. Consistent with the lower extent of neovascularization in the V- tumors, TMZ and MTIC tumor concentrations were not different in TNP-470 and control treatment groups in s.c. tumors. MVD was reduced by TNP-470 compared with vehicle control in the V+ tumors, but was unaltered in V- tumors, attesting to the use of MVD as a pharmacodynamic end point and the effectiveness of TNP-470 as an angiogenesis inhibitor. Angiogenesis inhibitor's pharmacodynamic actions on tumor angiogenesis can produce a reduction in tumor concentrations of coadministered anticancer agents. It is increasingly important to understand the pharmacokinetic and pharmacodynamic behavior of each class of drug so that optimal dosing regimens can be designed.

Angiogenesis inhibitors in clinical development; where are we now and where are we going?

Angiogenesis is crucial for tumour growth and the formation of metastases. Various classes of angiogenesis inhibitors that are each able to inhibit one of the various steps of this complex process can be distinguished. Results from clinical studies with these agents are summarised. In general, it has been shown that most angiogenesis inhibitors can be safely administered, but that tumour regressions are rare. Combining angiogenesis inhibitors with cytotoxic chemotherapy can enhance anticancer activity. Recently, some promising data with regard to clinical efficacy have been presented. While performing clinical studies with angiogenesis inhibitors, defining biological activity is crucial, but thus far no validated techniques are available. It is conceivable that in the near future various classes of angiogenesis inhibitors will be combined in an attempt to further improve antiangiogenic and anticancer activity.

Treatment of metastatic liver tumors by intermittent repetitive injection of an angiogenesis inhibitor using an implantable port system in a rabbit model.

Angiogenesis inhibitors are expected as a new type of anticancer drug, because they may prevent tumor neovascularization. Among several angiogenesis inhibitors, 6-o-(N-chloroacetylcarbamoyl)-fumagillol (TNP-470) is thought to inhibit the proliferation of migrating endothelial cells, as an aspect of angiogenesis, and attracts an attention for clinical application. We attempted to evaluate anticancer effects of intermittent repetitive intraportal injection of TNP-470 for metastatic liver tumor models and considered the usefulness and a role as an angiogenesis inhibitor, TNP-470, in the anti-cancer therapy using an implantable port system. We used 25 Japanese white rabbits with metastatic liver tumors made by intraportal injection of tumor cells (VX2-carcinoma), and divided those into five groups; group A was control group, group B was treated by repetitive subcutaneous injection of TNP-470 and group C, D, E was treated by repetitive intraportal injection of TNP-470, adriamycin, TNP-470 + adriamycin respectively 5 times at 2 or 3 days interval after tumor inoculation using implantable port systems. After 2 weeks, we evaluated anti-cancer effect of TNP-470 pathologically. In the number of grown tumors, there was no difference among five groups statisitically. But the mean tumor size of each group is smaller in order of group E, D, C, B, A and the differences were significant (P < 0.05) except between E and D group. And intratumoral neovascularization tended to be less in group B, C, E than in group A, D pathologically. We consider that intermittent repetitive injection of TNP-470 is more useful than systemic administration for metastatic liver tumors and the administration of angiogenesis inhibitor with other anti-cancer agents via an implantable port system will be one of the most effective therapeutic methods for them.

Angiogenesis inhibitor TNP-470 inhibits murine cutaneous wound healing.

BACKGROUND: TNP-470 (AGM-1470) is a potent inhibitor of angiogenesis with potential therapeutic applications in neoplastic and angio-proliferative diseases. This study evaluated its effect on cutaneous wound healing in a murine dorsal excisional wound model. MATERIALS AND METHODS: Full-thickness wounds (1.60 cm2) were created on the dorsum of homozygous/hairless mice (7 to 9 weeks). Wound areas were measured on alternate days for 16 days. Experimental groups consisted of (1) TNP-470 administered in doses of 0.05, 0.5, and 5.0 mg/kg on Days 0, 2, and 4 or Days 0 through 6; (2) TNP-470 (5.0 mg/kg) coadministered with minocycline (4.0 and 10 mg/kg) on Days 0, 2, and 4; and (3) TNP-470 (5.0 mg/kg on Days 0, 2, and 4) coadministered with topical basic fibroblast growth factor (bFGF) 1. 0 microg/wound on Days 0, 1, and 2. Hematoxylin and eosin staining was used to compare experimental and control wounds. RESULTS: TNP-470 administration significantly decreased wound healing in a dose-dependent manner versus controls (P <.05). The 5.0 mg/kg concentration yielded the greatest effect by maintaining an average wound area 20.4% greater than controls and a marked delay in wound healing on H&E staining. Alternate-day dosing was as effective as consecutive day administration. Minocycline did not augment the wound healing inhibition of TNP-470. Coadministration of TNP-470 and bFGF eliminated any rate-altering effect of TNP-470 upon wound healing and resulted in wound areas similar to controls. CONCLUSION: Therapy with TNP-470 induces a significant delay in murine cutaneous wound healing. This effect may be exploited for use in situations where wound healing is excessive and debilitating. Topical application of bFGF can overcome TNP-470-induced wound healing inhibition.

Angiozyme: a novel angiogenesis inhibitor.

Several inhibitors of angiogenesis are being developed for the treatment of cancer. One dominant strategy involves disruption of the vascular endothelial growth factor (VEGF) pathway by inhibition of the receptors for VEGF. Inhibition of the VEGF receptor activity can be accomplished using catalytic RNA molecules known as ribozymes, which downregulate VEGF receptor function by specifically cleaving the mRNAs for the primary VEGF receptors, Flt-1 and KDR. Significant inhibition of angiogenesis using ribozymes against both receptors has been demonstrated. In animal tumor models, antitumor effects are most pronounced with the anti-Flt-1 ribozyme known as Angiozyme (Ribozyme Pharmaceuticals, Boulder, CO). Extensive preclinical studies have demonstrated no significant toxicities. Clinical trials of Angiozyme are currently in progress for patients with advanced malignancy. Preliminary results demonstrate Angiozyme to be well tolerated, without significant side effects. Several phase II trials are underway for patients with advanced malignancy to test therapeutic efficacy.

Troponin I peptide (Glu94-Leu123), a cartilage-derived angiogenesis inhibitor: in vitro and in vivo effects on human endothelial cells and on pancreatic cancer.

Several inhibitors of angiogenesis have been identified in bovine and shark cartilage. One of them is troponin I, which is the molecule responsible for the inhibition of the actomyosin ATPase during muscle contraction. In this study we sought to investigate if the active site of troponin I (peptide Glu94-Leu123; pTnI) is also the one responsible for the antiangiogenic properties of this protein. The effects of pTnI on endothelial cell tube formation and endothelial cell division were investigated using human umbilical vein endothelial cells, Matrigel, light microscopy, carboxyfluorescein diacetate, succinimidyl esterlabeling, and flow cytometry. Its effects on induction of ICAM-1 and production of vascular endothelial growth factor by pancreatic cancer cells (CAPAN-1) were also investigated, as was its efficacy in a mouse model of pancreatic cancer metastases. Our results show that concentrations as low as 1 pg/ml of pTnI significantly inhibit endothelial cell tube formation, and that endothelial cell division was inhibited at 96 hours by 3 microg/ml pTnI (P=0.0001). No effects were seen using troponin peptide 124-181 as a control. pTnI-treated supernatant from the pancreatic cancer cell line CAPAN-1 downregulated ICAM-1 expression on human umbilical vein endothelial cells up to 10 ng/ml pTnI, and a significant reduction in vascular endothelial growth factor production was seen by treating CAPAN-1 cells with up to 1 microg/ml pTnI. After intrasplenic injection of CAPAN-1 cells, mice treated with pTnI had fewer liver metastases compared to control mice (liver/body weight 5.5 vs. 11.1; P=0.03). The active region of troponin I is the one responsible for its antiangiogenic effect. The mechanism of action of this peptide is probably multifactorial.

Polycystin-2 interacts with troponin I, an angiogenesis inhibitor.

Polycystin-2 (PC2), encoded by the PKD2 gene, is mutated in 10-15% of autosomal dominant polycystic kidney disease (ADPKD) patients. PC2 is a Ca(2+)-permeable nonselective cation channel and is present in kidney and many other organs. Likewise, PKD2-mutated patients and mice exhibit extrarenal abnormalities. In comparison with cysts in the kidney, liver, and pancreas, abnormalities in the heart, brain, and vascular vessels are less understood. In particular, roles of PC2 in muscle and endothelia remain largely unknown. In the present study, using a yeast two-hybrid screening, we discovered that the PC2 carboxyl terminal domain (D682-V968) interacts with the cardiac troponin I, an important regulatory component of the actin microfilament in cardiac muscle cells. This interaction was demonstrated by GST pull-down and microtiter binding assays. Dose-dependent binding between PC2 and troponin I followed a Michaelis-Menten relationship, indicating a 1:1 binding stoichiometry. The interacting domains were located to the R872-H927 segment of PC2 and the M1-V107 and K106-L158 segments of troponin I. Co-immunoprecipitation experiments demonstrated that the cardiac and two skeletal isoforms of troponin I were all associated with PC2, when coexpressed in mouse fibroblast NIH 3T3 cells and Xenopus oocytes. Furthermore, reciprocal co-immunoprecipitation verified the interaction between the native polycystin-2 and troponin I in human adult heart tissues. This study thus provides new evidence for a direct attachment of PC2 to the actin microfilament network, in addition to the recently identified association between PC2 and trypomyosin-1. Troponin I functions as an inhibitory subunit of the troponin complex for calcium-dependent regulation of muscle contraction and as an inhibitor of angiogenesis seen in ADPKD. It is possible that altered interaction due to pathogenic polycystin-1 or -2 mutations can account for angiogenesis in ADPKD and may be corrected to some extent by exogenous troponin I.
