2.Anti-angiogenesis in Lung Cancer: Current Situation, Progress and Confusion.
Chinese Journal of Lung Cancer 2022;25(4):278-286
Lung cancer is a highly vascular tumors, over the past ten years, anti-angiogenes is has been proved to be an effective and highly promising combinational treatment. The data of the combination of anti-angiogenesis with chemotherapy, targeted therapy, immunotherapy has been constantly updating. Advanced lung cancer patients, no matter different groups or different stages of the disease, are benefited from anti-angiogenes. In this paper, based on the clinical status and unsolved problems, combined with the latest clinical and translational research data, we reviewed the current anti-angiogenesis treatment of lung cancer.

3.Mechanism exploration and future prospects of antiangiogenic agents improving tumor blood supply and oxygenation.
Chinese Journal of Gastrointestinal Surgery 2014;17(11):1148-1151
The growth and metastasis of tumor is angiogenesis-dependent. Antiangiogenic agents have been clinically used to treat malignant tumors with the mechanisms of regressing tumor vasculature and inhibiting vascular recurrence which restrain tumor growth and metastasis. Clinical evidences indicate that antiangiogenic agents combined with chemotherapy or radiotherapy potentiate the effects of treatment. However, radiation therapy and chemotherapy depend on ample blood flow to the tumor to deliver oxygen and drugs. Theoretically, it is paradoxical with evidences that these therapies work together rather than against each other. "Vascular normalization" theory was raised to explain this paradox. And accumulating data show that antiangiogenic agents transiently "normalize" tumor vasculature before causing vascular regression, so that improve tumor blood supply and increase tissue oxygenation. New views and challenges about antiangiogenic agents come out with the discovery of "normalization window". In this review, we summarized the mechanism, related researches and future prospects of antiangiogenic agents improving blood supply and oxygenation.

4.Endostatin derivative angiogenesis inhibitors.
Chinese Medical Journal 2009;122(16):1947-1951
OBJECTIVETo throw light on the superiority of the anti-angiogenesis activity of endostatin (ES) derivatives by reviewing the recent progress in the field of ES molecular structure modification.
DATA SOURCESThe data used in this article were mainly from PubMed with relevant English articles published from 1971 to May 2008. The search terms were "endostatin" and "angiothesis".
STUDY SELECTIONArticles involved in the ES molecular structure modification and the original milestone articles were selected.
RESULTSA number of ES derivatives were designed and studied to improve its clinical relevance. The modified ES with polyethylene glycol (PEG), low molecular weight heparin (LMWH) and IgG Fc domain extended the circulation half-life. Meanwhile the recombinant ESs showed more potent anti-tumor activity than native ES in mouse xenografts. Mutated ES also changed its anti-angiogenesis activity.
CONCLUSIONSThe anti-angiogenesis treatment remains a promising tumor therapeutic strategy. New ES derivatives would be a good choice to meet the future challenge on clinical application of ES.

Neuropilins (NRP1 and NRP2) are multifunctional receptor proteins that are involved in nerve, blood vessel, and tumor development. NRP1 was first found to be expressed in neurons, but subsequent studies have demonstrated its surface expression in cells from the endothelium and lymph nodes. NRP1 has been demonstrated to be involved in the occurrence and development of a variety of cancers. NRP1 interacts with various cytokines, such as vascular endothelial growth factor family and its receptor and transforming growth factor β1 and its receptor, to affect tumor angiogenesis, tumor proliferation, and migration. In addition, NRP1+ regulatory T cells (Tregs) play an inhibitory role in tumor immunity. High numbers of NRP1+ Tregs were associated with cancer prognosis. Targeting NRP1 has shown promise, and antagonists against NRP1 have had therapeutic efficacy in preliminary clinical studies. NRP1 treatment modalities using nanomaterials, targeted drugs, oncolytic viruses, and radio-chemotherapy have gradually been developed. Hence, we reviewed the use of NRP1 in the context of tumorigenesis, progression, and treatment.

7.Antiangiogenesis therapy: an update after the first decade.
The Korean Journal of Internal Medicine 2014;29(1):1-11
Angiogenesis is a complex biological phenomenon that forms new blood vessels from the pre-existing vasculature. Aberrant angiogenesis has been implicated in a variety of diseases such as cancer, atherosclerosis, arthritis, obesity, pulmonary hypertension, diabetic retinopathy, and age-related macular degeneration. These conditions collectively affect nearly 10% of the global population. Much effort has focused on identifying new therapeutic agents that inhibit pathological angiogenesis since 1971, when Judah Folkman published the hypothesis that tumor growth is angiogenesis-dependent and that its inhibition may be therapeutic. In 2004, the U.S. Food and Drug Administration approved the first antiangiogenic drug for the treatment of metastatic colon cancer, bevacizumab (Avastin, Genentech). This drug is a humanized monoclonal antibody that neutralizes the vascular endothelial growth factor. It is used in combination with chemotherapy, and its use began the era of antiangiogenesis therapy. Several new therapeutic agents have been added to the list of approved drugs, and clinical trials of new therapeutic options and antiangiogenic agents are ongoing. This review describes the progress made in the first decade of antiangiogenesis therapy, and addresses both validated and possible targets for future drug development.

Regulation of tumor vessels has become one of the most common strategies for clinical anti-tumor therapy. In recent years, studies have found that the anti-tumor effect of limotherapy, which routinely inhibits tumor angiogenesis, is not ideal and may even deteriorate the tumor microenvironment, causing tumor resistance and distal metastasis and increasing the risk of tumor metastasis and recurrence. However, the proper use of anti-angiogenic drugs can promote the normalization of tumor vessels, improve the structure and function of tumor vessels, increase the number of functional vessels in the tumor, and reduce the number of ineffective vessels. It is beneficial to promote the penetration of anti-tumor drugs into the tumor, improve the microenvironment of tumor hypoxia and immunosuppression, and enhance the anti-tumor effect. Traditional Chinese medicine(TCM) has a long history of understanding the etiology and pathogenesis of tumors and has accumulated rich experience in tumor treatment, with significant clinical advantages and broad application prospects. In this study, from the perspective of bidirectional "soothing" or "blockage" regulation of tumor vessels, the commonly used molecular targets were sorted out, and the research status of anti-tumor regulation of tumor vessels by monomer-single herb-compound(herb pair) of TCM in recent years was summarized. The research on the anti-tumor effects of TCM compounds and active ingredients by regulating tumor vessels combined with other therapies was analyzed and sorted out, so as to provide ideas for the clinical application of TCM in regulating functions and anti-tumor effects of tumor vessels.

Retinopathy of prematurity(ROP)is a pathological neovascularization with fibrotic changes in the fundus of premature infants.It is a major cause of preventable blindness in children in both developing and developed countries.Treatment of ROP has long been a hot research topic in ophthalmology and pediatrics.With a clearer knowledge of the pathogenesis of ROP,more basic and clinical studies have been carried out.The anti-vascular endothelial growth factor therapy and surgical treatment have become mature strategies,and a variety of therapeutic drugs including insulin-like growth factor-1,transforming growth factor-β,polyunsaturated fatty acids,and β-adrenergic receptor blockers have been developed.This article reviews the recent advances in ROP.

10.Research advance in antitumor activities of artemisinin and its derivatives.
Acta Academiae Medicinae Sinicae 2013;35(4):466-471
Artemisinin and its derivatives are highly effective in fighting against malaria. Notably, these drugs have shown potent anti-timor activities by arresting cellular growth, enhancing apoptosis, inhibiting angiogenesis, and regulating the expression of tumor-associated genes, although the underlying mechanisms remain unclear.
