Human Verification

Angiogenesis is a dynamic and complicated multistep process involving the activation, invasion, migration, proliferation, sprout formation, tube formation, and finally capillary network formation of vascular endothelial cells.

All of these steps are essential for the success of angiogenesis and are controlled directly or indirectly by the dynamic balance between angiogenic stimulators and inhibitors.

Thus, investigating the cellular and molecular regulatory mechanism of angiogenesis provides potential drug targets to block angiogenesis. Sustained tumor angiogenesis is one of the hallmark features of cancer.

Tumor angiogenesis refers to the ability of a tumor to stimulate new blood vessel formation to support tumor expansion, local invasion, and dissemination. To grow beyond a critical size or metastasize to another organ, a tumor must stimulate and maintain a network of new blood vessels.

The extent of angiogenesis is determined by the balance between the angiogenic stimulators and inhibitors in the microenvironment of the neoplastic tissue. VEGF is one of the key angiogenic stimulators secreted by the tumor cells to switch on the angiogenic phenotype.

Intratumor hypoxia and alteration in oncogenes and tumor suppressor genes significantly upregulate VEGF expression. Many cancer cells, including carcinomas of the breast, kidney, colon, brain, ovary, cervix, thyroid, bladder, esophagus, and prostate, overexpress VEGF.

In addition, the 3-D extracellular matrix ECM environment also plays an active role in the regulation of tumor angiogenesis and tumor invasion.

Tumor cells and angiogenic endothelial cells use ECM receptors, such as integrin anb3, to bind the surrounding matrix and invade.

They also loosen the surrounding matrix by proteolytically degrading the basement membrane using proteinases such as plasminogen activator, matrix metalloproteinase MMP , chymase, or heparanase. Furthermore, these proteinases regulate angiogenesis by activating or releasing angiogenic stimulators i.

Thus, many investigative antiangiogenesis drugs are targeting angiogenic stimulators, ECM receptors, and ECM proteinases.

Under normal physiologic conditions, angiogenesis is well controlled by the local balance between endogenous angiogenesis stimulators and angiogenesis inhibitors, although the regulatory mechanism is still not clear.

Most of the endogenous angiogenic inhibitors can be categorized as matrix derived, such as endostatin, and nonmatrix derived, such as interferons and angiostatin. At least 30 endogenous angiogenesis inhibitors can be detected in blood circulation, indicating that these angiogenesis inhibitors play an important role in maintaining the angiogenic balance under physiologic conditions.

During wound healing, the expression of VEGF, one of the most potent angiogenic stimulators, is significantly upregulated to promote wound healing by restoring blood flow to injured tissues. As wound healing resolves, the expression of VEGF is downregulated and most angiogenic capillaries regress, resulting in a residual normal vascularity.

Deficient production of angiogenic stimulators turns off the angiogenesis switch and leads to insufficient angiogenesis. Inordinate production of angiogenic stimulators turns on the angiogenesis switch and drives excessive angiogenesis.

Both insufficient and excessive angiogenesis contribute to the pathogenesis of many major diseases. Under pathologic conditions, insufficient angiogenesis occurs in coronary artery disease, stroke, and chronic wounds. Excessive angiogenesis occurs mostly when diseased cells, such as inflammatory and tumor cells, produce abnormal amounts of angiogenic stimulators, overwhelming the effects of endogenous angiogenesis inhibitors, thus turning on the angiogenesis switch.

Most important, during cancer development the human body loses control over the balance between angiogenesis stimulators and inhibitors, which leads to excessive angiogenesis that feeds the tumor growth and facilitates tumor metastasis. Also of clinical interest, colorectal and breast cancer patients specifically showed increased concentrations in VEGF-A and MMP-9 plasma levels due to malignancy.

These levels are reduced after the tumor is removed, which significantly decreases the extent of angiogeneses. Excessive angiogenesis is seen in diseases such as solid tumor cancers, diabetic retinopathy, age-related macular degeneration, rheumatoid arthritis, and psoriasis, as well as other diseases.

In these conditions, new blood vessels feed diseased tissues and destroy normal tissues. In the case of cancer, tumor cells produce and secrete excessive amounts of many potent angiogenic stimulators, such as VEGF, placental growth factor PlGF , stromal-cell—derived factor 1, and angiopoietin These angiogenic stimulators will activate the complicated multistep angiogenesis process surrounding the tumor microenvironment.

New evidence indicates that these angiogenic factors also stimulate the mobilization of cells at distant sites, including bone marrow, into circulation to promote vascularization.

Angiogenesis is a tightly regulated multistep process. Many enzymes, growth factors, ECM proteins, ECM receptors, and their signal transduction pathways involved in the regulation of angiogenesis can be potential targets for angiogenesis therapy. Drugs based on blocking monoclonal antibodies and chemical inhibitors are being developed to counter the effect of angiogenesis growth factors.

Other positive regulators are angiopoietin-1, angiotropin, angiogenin, epidermal growth factor EGF , granulocyte colony-stimulating factor, interleukin IL -1, IL-6, IL-8, and platelet-derived growth factor PDGF.

Since VEGF plays an essential role in stimulating tumor angiogenesis, blocking VEGF-mediated signaling pathways has been one of the major strategies for antiangiogenesis therapy.

Currently, there are six members in the VEGF family i. These VEGF proteins bind in a distinct pattern to three structurally related receptor tyrosine kinases known as VEGF receptor VEGFR -1, -2, and Monoclonal antibodies against VEGF or VEGFR and small molecule inhibitors of VEGFR tyrosine kinase and its downstream signal transduction pathway are some of the major antiangiogenesis therapeutic agents.

The first successful treatment of an angiogenesis-dependent disease occurred in , when the drug interferon alfa-2a was used to suppress angiogenesis by inhibiting VEGF and bFGF production, which led to regression of abnormal blood vessels growing in the lungs of a boy with pulmonary hemangiomatosis.

In February , bevacizumab Avastin , a humanized blocking monoclonal antibody for VEGF, was approved to treat metastatic colorectal cancer in combination with 5-FU.

Since then, bevacizumab in combination with standard chemotherapy agents has been found efficacious in clinical trials of non—small cell lung cancer NSCLC , renal cell carcinoma RCC , glioblastoma, ovarian cancer, and breast cancer.

More recently, aflibercept VEGF Trap in combination with standard chemotherapy regimens is undergoing phase II and phase III clinical trials in the treatment of advanced solid tumors in five different cancers: colorectal cancer, NSCLC, prostate cancer, pancreatic cancer, and gastric cancer.

Aflibercept is a fused protein comprised of segments of the extracellular domains of human VEGFR-1 and VEGFR-2, and constant region Fc of human immunoglobulin G IgG.

Aflibercept inhibits angiogenesis by functioning as a soluble decoy receptor to trap VEGFs. In addition to the ligand blocking agents, antiangiogenesis drugs are also being developed to block the signal transduction pathway for angiogenesis stimulators.

Several small molecular-weight receptor tyrosine kinase RTK inhibitors such as sunitinib Sutent and sorafenib Nexavar , have been developed to target the signal transduction pathway of angiogenic stimulators, such as VEGF, EGF, and PDGF. In , both sunitinib and sorafenib were approved by the FDA for advanced RCC.

In October , the FDA granted approval to pazopanib Votrient for the treatment of patients with advanced RCC. A variety of other small-molecule RTK inhibitors targeting the VEGF and EGF receptors signal transduction pathway have been approved by the FDA for the treatment of solid tumor cancers, including gefitinib Iressa and erlotinib Tarceva.

Some clinical studies indicate that nilotinib is active in GIST resistant to both imatinib and sunitinib.

Other small-molecule agents under clinical investigation include motes-anib, vatalanib, and vandetanib. The discovery of downstream signal-transduction pathways for RTK has also led to the development of many newly targeted agents.

As one of the key protein kinases controlling signal transduction from various growth factors and upstream proteins to the level of mRNA translation and ribosome biogenesis , mammalian target of rapamycin mTOR plays a critical role in regulating cell cycle progression, cellular proliferation and growth, and angiogenesis.

Temsirolimus is recommended as first-line treatment for patients with poor-prognosis metastatic RCC. In , the FDA approved everolimus Afinitor, also known as RAD as the second drug in the class of mTOR inhibitors for the treatment of advanced RCC after failure of treatment with sunitinib or sorafenib.

Interestingly, research on some of the previously approved chemotherapeutic agents, such as doxorubicin and cisplatin, demonstrates that they inhibit VEGF production. Thalidomide inhibits angiogenesis mediated by VEGF and bFGF, and studies have shown that thalidomide in combination with dexamethasone has increased the survival of multiple myeloma patients.

In addition to the chemotherapeutic and endogenous angiogenesis inhibitors, natural sources with antiangiogenic properties include tree bark, fungi, shark muscle and cartilage, sea coral, green tea, and herbs such as licorice, ginseng, cumin, and garlic.

In total, more than angiogenesis inhibitors have been discovered to date. Although they may not necessarily directly kill tumor cells, angiogenesis inhibitors significantly enhance the efficacy of standard chemotherapy and radiation therapy by inhibiting tumor growth and tumor metastasis.

Therefore, this type of therapy may need to be administered over a long period of time. Since antiangiogenesis therapy is a targeted therapy aimed specifically at the angiogenic stimulators and the angiogenic microvascular endothelial cells, antiangiogenesis therapy usually produces only mild side effects and is less toxic to most healthy cells.

Approved angiogenesis inhibitors include:. Side effects of treatment with VEGF-targeting angiogenesis inhibitors can include hemorrhage , clots in the arteries with resultant stroke or heart attack , hypertension , impaired wound healing, reversible posterior leukoencephalopathy syndrome a brain disorder , and protein in the urine.

Gastrointestinal perforation and fistulas also appear to be rare side effects of some angiogenesis inhibitors. Antiangiogenesis agents that target the VEGF receptor have additional side effects, including fatigue, diarrhea, biochemical hypothyroidism , hand-foot syndrome , cardiac failure, and hair changes.

How do angiogenesis inhibitors work? What angiogenesis inhibitors are being used to treat cancer in humans? Do angiogenesis inhibitors have side effects? What is angiogenesis?

Approved angiogenesis inhibitors include: Axitinib Inlyta® Bevacizumab Avastin® Cabozantinib Cometriq® Everolimus Afinitor® Lenalidomide Revlimid® Lenvatinib mesylate Lenvima® Pazopanib Votrient® Ramucirumab Cyramza® Regorafenib Stivarga® Sorafenib Nexavar® Sunitinib Sutent® Thalidomide Synovir, Thalomid® Vandetanib Caprelsa® Ziv-aflibercept Zaltrap®.

So anti angiogenic drugs are treatments that stop tumours from growing their own blood vessels. If the drug is able to stop a cancer from growing blood vessels, it might slow the growth of the cancer or sometimes shrink it.

Some cancer cells make a protein called vascular endothelial growth factor VEGF. The VEGF protein attaches to receptors on cells that line the walls of blood vessels within the tumour. The cells are called endothelial cells. This triggers the blood vessels to grow so the cancer can then grow.

Some drugs block vascular endothelial growth factor VEGF from attaching to the receptors on the cells that line the blood vessels. This stops the blood vessels from growing. An example of a drug that blocks VEGF is bevacizumab Avastin.

Bevacizumab is also a monoclonal antibody. It is a treatment for several different types of cancer. Other examples include:. Some drugs stop the VEGF receptors from sending growth signals into the blood vessel cells.

These treatments are also called cancer growth blockers or tyrosine kinase inhibitors TKIs. Some drugs act on the chemicals that cells use to signal to each other to grow.

This can block the formation of blood vessels. Drugs that works in this way include thalidomide and lenalidomide Revlimid.

If an angiogenesis inhibitor is recommended for you, talk with your doctor about the specific potential benefits and risks of that medication. Also, ask about ways side effects can be managed and what side effects to watch for.

Angiogenesis inhibitors for cancer can be prescribed by a doctor to take orally by mouth or intravenously by vein; IV. If you are prescribed an oral angiogenesis inhibitor to take at home, ask if you need to fill the prescription at a pharmacy that handles complex medications, such as a specialty pharmacy.

Check with the pharmacy and your insurance company about your insurance coverage and co-pay of the oral medication. Also, be sure to ask about how to safely store and handle your prescription at home.

If you are prescribed an IV treatment, that will be given at the hospital or other cancer treatment facility. Talk with your treatment center and insurance company about how your specific prescription is covered and how any co-pays will be billed.

If you need financial assistance, talk with your health care team, including the pharmacist or a social worker , about co-pay assistance options. National Cancer Institute: Angiogenesis Inhibitors. The Angiogenesis Foundation: Treatments.

Skin hydration secrets angiogenic drugs Amti-angiogenesis treatments that strategiew tumours from growing their own blood vessels. This might slow the growth of the cancer or sometimes shrink it. A cancer needs a good blood supply to provide itself with food and oxygen and to remove waste products. When it has reached 1 to 2 mm across, a tumour needs to grow its own blood vessels in order to continue to get bigger.
