Background: Epstein-Barr virus (EBV) actively contributes to the pathological process of nasopharyngeal carcinoma (NPC) by enabling NPC cells to acquire various capacities required for their malignant biological actions. Our earlier works demonstrated that EBV-encoded latent membrane protein 1 (LMP1) enhanced vascular endothelial growth factor (VEGF)-mediated angiogenesis by boosting store-operated Ca2+ entry (SOCE) upon extracellular epidermal growth factor (EGF) stimulation. However, the antagonistic effects of SOCE blockage on EBV-promoted angiogenesis must be appropriately evaluated in vivo, and the global effect of EBV infection on the EGF-elicited cytosolic Ca2+ signaling, which regulates VEGF-mediated angiogenesis remains to be further clarified...

There is general agreement that increased angiogenesis is an important factor in determining prostate cancer development and prognosis. Vascular Endothelial Growth Factor (VEGF) is thought to play a primary role in the molecular events that lead to prostate cancer progression, from androgen-dependency to castration-resistance until dissemination to the skeleton. Bevacizumab is a recombinant anti-VEGF monoclonal antibody that has exhibited clinical activity in different cancer types. Areas covered: In this review we summarize the data of clinical trials, investigating the effects of bevacizumab in prostate cancer patients...

Starting from the phase II clinical FGFR inhibitor lucitanib (2), we conducted a medicinal chemistry approach by opening the central quinoline skeleton coupled with a scaffold hopping process thus leading to a series of novel 2-benzamide-4-(6-oxy-N-methyl-1-naphthamide)-pyridine derivatives. Compound 25a was identified to show selective and equally high potency against FGFR1/2 and VEGFR2 with IC50 values less than 5.0 nM. Significant antiproliferative effects on both FGFR1/2 and VEGFR2 aberrant cancer cells were observed...

In addition to the crucial role in promoting the growth of tumor vessels, vascular endothelial growth factor (VEGF) is also immunosuppressive. VEGF can inhibit the function of T cells, increase the recruitment of regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs), and hinder the differentiation and activation of dendritic cells (DCs). Recent studies have investigated the role of antiangiogenic agents in antitumor immunity, especially in recent 3 years. Therefore, it is necessary to update the role of targeting VEGF/VEGFR in antitumor immunity...

Mesenchymal stromal/stem cells (MSCs) have been promising source for regenerative cell therapy in ischemic diseases. To improve efficacy of MSC therapy, various priming methods have been developed, and hypoxic priming has been reported to enhance therapeutic efficacy of MSCs by increasing secretion level of growth factors and cytokines. Recently, it has been reported that bone marrow MSCs primed with hypoxic condition show an increase of autophagy. Here, we addressed whether proangiogenic activity increased by hypoxic condition is associated with autophagy...

BACKGROUND: The standard treatment for metastatic renal cancer is based on vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTor) inhibitors. Compared to other advanced tumors, the treatment of renal cancer is highly affected by impaired renal function; therefore, patients with severe renal insufficiency, including patients on hemodialysis, are generally excluded from clinical trials. CASE REPORT: In the present manuscript we present the case of a renal cancer patient who underwent bilateral nephrectomy and received two lines of treatment...

Metastatic colorectal cancer still remains an essentially non curable disease. However, with advances in chemotherapeutic and personalizing therapeutic approaches with the incorporation of targeted therapy such as anti-EGFR and anti-VEGF agents survival associated with metastatic colorectal cancer has certainly improved over the last two decades. Patients who are not amenable to surgery median survival remain approximately 2 to 3 years. In an attempt to improve prognostic outcome over the last decade research has focused on therapeutic options geared towards harnessing the immune system with success observed with the use of immune checkpoint inhibitors in the realm of a number of solid tumors including lung and renal cancer...

BACKGROUND Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have been widely used in the treatment of non-small cell lung cancer (NSCLC) patients with sensitive EGFR mutations. However, the survival of patients with EGFR-TKI administration is limited by the inevitable development of acquired drug resistance. Recently, multi-targeted drugs combination has been shown to be a promising strategy to improve the efficacy of EGFR-TKI treatment and enable the reduction of drug resistance in NSCLC...

NK cells are effector lymphocytes involved in tumor immunosurveillance; however, in patients with solid malignancies, NK cells have compromised functions. We have previously reported that lung tumor-associated NK cells (TANKs; peripheral blood) and tumor-infiltrating NK cells (TINKs) show proangiogenic, decidual NK-like (dNK) phenotype. In this study, we functionally and molecularly investigated TINKs and TANKs from blood and tissue samples of patients with colorectal cancer (CRC), a neoplasm in which inflammation and angiogenesis have clinical relevance, and compared them to NK cells from controls and patients with nononcologic inflammatory bowel disease...

Autophagy, interacting with actin cytoskeleton and the NO-dependent pathway, may affect the phenotype and function of endothelial cells. Moreover, caveolin-1 (Cav-1), as a structure protein in liver sinusoidal endothelial cells (LSECs), is closely related to autophagy. Hence, we aim to explore the role of autophagic degradation of Cav-1 in LSECs defenestration. In vivo, we found the increase of autophagy in liver sinusoidal endothelium in human fibrotic liver. Furthermore, autophagy, degradation of Cav-1, and actin filament (F-actin) remodeling were triggered during the process of CCl4-induced LSECs defenestration; in contrast, autophagy inhibitor 3MA diminished the degradation of Cav-1 to maintain fenestrae and relieve CCl4-induced fibrosis...

Glioblastoma, characterized by extensive microvascular proliferation and invasive tumor growth, is one of the most common and lethal malignancies in adults. Benefits of the conventional anti-angiogenic therapy were only observed in a subset of patients and limited by diverse relapse mechanism. Fortunately, recent advances in cancer immunotherapy have offered new hope for patients with glioblastoma. Herein, we reported a novel dual-targeting therapy for glioblastoma through simultaneous blockade of VEGF and CD47 signaling...

Emerging therapies have begun to evaluate the abilities of Müller glial cells (MGCs) to protect and/or regenerate neurons following retina injury. The migration of donor cells is central to many reparative strategies, where cells must achieve appropriate positioning to facilitate localized repair. Although chemical cues have been implicated in the MGC migratory responses of numerous retinopathies, MGC-based therapies have yet to explore the extent to which external biochemical stimuli can direct MGC behavior...

Gliomas are one of the most common and most aggressive types of central nervous system tumor. Angiogenesis is an important basis for the growth of solid tumors, including gliomas, which is regulated by microRNAs (miRNAs). However, the mechanism remains unclear. Recently, it was demonstrated that miR‑24 was upregulated in gliomas, so the aim of the present study is to establish whether the dysregulation of miR‑24 in glioma cells promotes microvascular proliferation of endothelial cells (ECs), and to investigate the potential mechanism...

Due to the critical location and physiological activities of the retinal pigment epithelial (RPE) cell, it is constantly subjected to contact with various infectious agents and inflammatory mediators. However, little is known about the signaling events in RPE involved in Toxoplasma gondii infection and development. The aim of the study is to screen the host mRNA transcriptional change of 3 inflammation-related gene categories, PI3K/Akt pathway regulatory components, blood vessel development factors and ROS regulators, to prove that PI3K/Akt or mTOR signaling pathway play an essential role in regulating the selected inflammation-related genes...
