BACKGROUND: Tumor-induced lymphangiogenesis and lymphatic metastasis are predominant during the metastasis of many types of cancers. However, the endogenous inhibitors that counterbalance the lymphangiogenesis and lymphatic metastasis of tumors have not been well evaluated. Kallistatin has been recognized as an endogenous angiogenesis inhibitor. METHODS AND RESULTS: Our recent study showed for the first time that the lymphatic vessel density (LVD) was reduced in lung and stomach sections from kallistatin-overexpressing transgenic mice...

Background: Results from the BEVA2007 trial, suggest that the metronomic chemotherapy regimen with dose-fractioned cisplatin and oral etoposide (mPE) +/- bevacizumab, a monoclonal antibody to the vascular endothelial growth factor (VEGF), shows anti-angiogenic and immunological effects and is a safe and active treatment for metastatic non-small cell lung cancer (mNSCLC) patients. We carried out a retrospective analysis aimed to evaluate the antitumor effects of this treatment in a subset of patients with squamous histology...

Although it is well established that tumor-associated macrophages take part in each step of cancer progression, less is known about the distinct role of the so-called metastasis-associated macrophages (MAMs) at the metastatic site. Previous studies reported that Caveolin-1 (Cav1) has both tumor-promoting and tumor-suppressive functions. However, the role of Cav1 in bone-marrow-derived cells is unknown. Here, we describe Cav1 as an anti-metastatic regulator in mouse models of lung and breast cancer pulmonary metastasis...

Tumor angiogenesis plays essential roles during lung cancer progression and metastasis. Therapeutic agent that targets both tumor cell and vascular endothelial cell may achieve additional anti-tumor efficacy. We demonstrate that bedaquiline, a FDA-approved antibiotic drug, effectively targets lung cancer cells and angiogenesis. Bedaquiline dose-dependently inhibits proliferation and induces apoptosis of a panel of lung cancer cell lines regardless of subtypes and molecular heterogeneity. Bedaquiline also inhibits capillary network formation of human lung tumor associated-endothelial cell (HLT-EC) on Matrigel and its multiple functions, such as spreading, proliferation and apoptosis, even in the presence of vascular endothelial growth factor (VEGF)...

Mucin 1 (MUC1) is a transmembrane glycoprotein that is aberrantly unregulated in numerous types of cancer, including non-small cell lung cancer (NSCLC), and serves a key role as an oncogene in the tumorigenesis of various human adenocarcinomas. Studies have indicated that MUC1 is involved in cell proliferation, invasion and migration. However, the role of MUC1 in NSCLC progression remains poorly understood. The aim of the present study was to investigate the role of MUC1 in stable MUC1-low-expression NSCLC cell lines that were generated by transfection with MUC1-siRNA...

Itraconazole (ITA), an old and widely-prescribed antifungal drug with excellent safety profile, has more recently been demonstrated to be a multi-target anti-angiogenesis agent affecting multiple angiogenic stimulatory signals and pathways, including vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), vascular endothelial growth factor receptor 2 (VEGFR2) glycosylation, and mammalian target of rapamycin (mTOR). In this study, we developed two nanoparticle formulations, i.e., polymer micelles (IP2K) and albumin nanoparticles (IBSA), to solubilize the extremely hydrophobic and insoluble ITA to allow intravenous administration and pharmacokinetics (PK)/pharmacodynamics (PD) comparisons...

MicroRNA-200c (miR-200c) recently was found to have tumor-suppressive properties by inhibiting the epithelial-mesenchymal transition (EMT) in several cancers. miR-200c also interacts with various cellular signaling molecules and regulates many important signaling pathways. In this study, we investigated the radiosensitizing effect of miR-200c and its mechanism in a panel of human cancer cell lines. Malignant glioma (U251, T98G), breast cancer (MDA-MB-468), and lung carcinoma (A549) cells were transfected with control pre-microRNA, pre-miR-200c, or anti-miR-200c...

Genitourinary (GU) cancers are a group of epithelial malignancies associated with the organs involved in the excretion of urine. Renal cell, urothelial, and prostatic carcinoma are the overwhelming subtypes diagnosed by oncologists. Each of these was traditionally treated surgically when local and non-invasive. When these carcinomas spread, invade, or metastasize, surgical control lacks in efficacy. Chemotherapeutic regimens have been implemented for decades and have increased overall survival but many patients progress...

Astrocyte-elevated gene-1 (AEG-1) is implicated in the oncogenesis and angiogenesis of various types of human malignant disease. However, the angiogenesis roles of AEG-1 in non-small cell lung cancer (NSCLC) remain to be further elucidated. In the present study, the expression level of AEG-1 mRNA in seven human lung cell lines and 89 paired tissue samples (tumor tissues (TTs) and pair-matched normal adjacent tissues (PMNATs)) from NSCLC patients was detected by real-time PCR. Staining of vascular endothelial growth factor (VEGF) and intratumoral microvessel density (iMVD, labeled by CD105) were assessed by immunohistochemistry...

Arsenic trioxide (As2O3) exhibits a remarkable effect on leukemia treatment; however, its effect on solid tumors remains poorly explored. The present study demonstrated the inhibitory effect of As2O3 on lung cancer and explored its possible mechanism. It was observed that As2O3 significantly inhibited the growth of lung cancer xenografts and tumor angiogenesis in vivo. The inhibitory effect of As2O3 on cell proliferation in vitro was more remarkable in vascular endothelial cells than in lung cancer cells. It was also observed that As2O3 inhibited the migration of vascular endothelial cells and disrupted vascular tube formation on Matrigel assays...

Tumor-associated macrophages (TAM) are a major component of tumor stroma. It has been reported that TAMs have M2-like phenotype and facilitate tumor progression by promoting angiogenesis and immunosuppression. Melittin, a major polypeptide of bee venom, has been widely studied as an anti-cancer drug due to its cytotoxicity to malignant cells. However, very little is known regarding the effect of melittin on immune cells in the tumor microenvironment. This study focuses on the effect of melittin on TAMs in a Lewis lung carcinoma mouse model...

Non-small-cell lung cancer (NSCLC) is still the main threat of cancer-associated death. Current treatment of NSCLC has limited effectiveness, and unfortunately, the prognosis of NSCLC remains poor. Therefore, a novel strategy for cancer therapy is urgently needed. Stem cell therapy has significant potential for cancer treatment. Mesenchymal stem cells (MSCs) with capacity for self-renewal and differentiation into various cells types exhibit the feature of homing to tumor site and immunosuppression, have been explored as a new treatment for various cancers...

Vascular endothelial growth factor (VEGF) family members play critical and complex roles in the regulation of cancer vascularization and metastasis. The exact molecular control of lung cancer metastasis by VEGF family members is not completely understood. Here, we showed that specimens from non-small cell lung cancer (NSCLC) contained significantly higher levels of placental growth factor (PlGF) than paired non-cancer tissue (p < 0.05, N = 25). Moreover, higher levels of PlGF were detected in NSCLC specimens from the patients who had distal metastases than those who had not...

Introduction The vascular endothelial growth factor A (VEGF) is the main mediator of angiogenesis. In addition, VEGF contributes to cancer growth and metastasis directly targeting tumor cells. VEGF overexpression and/or high VEGF serum levels have been reported in lung cancer. Areas covered We searched Pubmed for relevant preclinical studies with the terms 'lung cancer' 'VEGF' and 'in vivo'. We also searched the Clinicaltrials.gov database, the FDA and the EMA websites for the most recent updates on clinical development of anti-VEGF agents...

Despite recent advances in metastatic lung cancer treatment with the advent of immune checkpoint inhibitors and molecules targeting addictive genomic abnormalities, prognosis of most of the patients remains unfavorable. Combination approaches with older drugs, such as bevacizumab, should be thus envisioned. Bevacizumab is a monoclonal anti-VEGF antibody, approved by the US FDA and the EMA in first-line and maintenance settings of advanced nonsquamous non-small-cell lung cancer (NSCLC) treatment, in association with platinum-based chemotherapy...

Clinical studies of pharmacological agents targeting the insulin like growth factor (IGF) pathway in unselected cancer patients have so far demonstrated modest efficacy outcomes, with objective responses being rare. As such, the identification of selection biomarkers for enrichment of potential responders represents a high priority for future trials of these agents. Several reports have described high IGF2 expression in a subset of colorectal cancers (CRC), with focal IGF2 amplification being responsible for some of these cases...
