Abstract
The incidence of gastric cancer is increasing year by year. Most gastric cancers are already in the advanced stage with poor prognosis when diagnosed, which means the current treatment is not satisfactory. Angiogenesis is an important link in the occurrence and development of tumors, and there are multiple anti-angiogenesis targeted therapies. To comprehensively evaluate the efficacy and safety of anti-angiogenic targeted drugs alone and in combination against gastric cancer, we systematically searched and sorted out relevant literature. In this review, we summarized the efficacy and safety of Ramucirumab, Bevacizumab, Apatinib, Fruquintinib, Sorafenib, Sunitinib, Pazopanib on gastric cancer when used alone or in combination based on prospective clinical trials reported in the literature, and sorted response biomarkers. We also summarized the challenges faced by anti-angiogenesis therapy for gastric cancer and available solutions. Finally, the characteristics of the current clinical research are summarized and suggestions and prospects are raised. This review will serve as a good reference for the clinical research of anti-angiogenic targeted drugs in the treatment of gastric cancer.

World J Orthop 2022; 13:538-543. [PMID: 35633745 PMCID: PMC9124998 DOI: 10.5312/wjo.v13.i5.538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Revised: 02/04/2022] [Accepted: 04/24/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gastrointestinal stromal tumors (GISTs) are rare primary neoplasms of the gastrointestinal tract, accounting for 1% to 2% of all gastrointestinal neoplasms worldwide. GISTs are frequently discovered incidentally during workup for other diagnosis or intestinal obstruction, as they can present with few or no symptoms. Simultaneously, GISTs confer a high degree of malignant transformation, with a progression in about 10% to 30% of cases.
CASE SUMMARY A 63-year-old healthy female presented to our institution with complaints of right knee pain and limited passive and active motion in the setting of a previous right total knee arthroplasty (TKA). One year after TKA, the patient was incidentally diagnosed with a GIST, which was successfully removed. After removal, the patient continued to have limited range of motion of the right knee and subsequently underwent revision TKA. Intraoperatively significant fibrotic adhesions were found encapsulating the femoral and tibial components. The patient’s pain improved postoperatively, however, she continued to have decreased range of motion with difficulty ambulating.
CONCLUSION We propose that this case may demonstrate a proinflammatory milieu arising from a GIST, which had a direct influence on the outcome of recent total knee arthroplasty. This proposed mechanism between neoplastic cytokinetic activity and adhesion formation could have implications on preoperative and postoperative orthopedic management of total knee arthroplasty.

Abstract
Most characterized angiogenic modulators are proteolytic fragments of structural plasma and/or matrix components. Herein, we have identified a novel anti-angiogenic peptide generated by the in vitro hydrolysis of the C-terminal moiety of the fibrinogen alpha chain, produced by the snake venom metalloprotease bothropasin (SVMP), a hemorrhagic proteinase in Bothrops jararaca venom. The 14-amino acids peptide (alphastatin-C) is a potent antagonist of basic fibroblast growth factor, induced endothelial cell (HUVEC-CS) proliferation, migration and capillary tube formation in matrigel. It also inhibits cell adhesion to fibronectin. The basis of the antagonism between bFGF and alphastatin-C is elucidated by the inhibition of various bFGF induced signaling pathways and their molecular components modification, whenever the combination of the stimuli is provided, in comparison to the treatment with bFGF only. To corroborate to the potential therapeutic use of alphastatin-C, we have chosen to perform in vivo assays in two distinct angiogenic settings. In chick model, alphastatin-C inhibits chorioallantoic membrane angiogenesis. In mouse, it efficiently reduces tumor number and volume in a melanoma model, due to the impairment of tumor neovascularization in treated mice. In contrast, we show that the alphastatin-C peptide induces arteriogenesis, increasing pial collateral density in neonate mice. alphastatin-C is an efficient new antiangiogenic FGF-associated agent in vitro, it is an inhibitor of embryonic and tumor vascularization in vivo while, it is an arteriogenic agent. The results also suggest that SVMPs can be used as in vitro biochemical tools to process plasma and/or matrix macromolecular components unraveling new angiostatic peptides.

Abstract
People with diabetes experience morbidity and mortality from unregulated microvascular remodeling, which may be linked to hyperglycemia. Elevated glucose leads to extracellular matrix collagen glycation, which delays endothelial capillary-like tube formation in vitro. Glucose also increases endothelial cell fibroblast growth factor-2 (FGF-2) release and extracellular matrix storage, which should increase tube formation. In this study, we determined if FGF-2 could restore plasminogen system activity and angiogenic function in endothelial cells on glycated collagen. Human umbilical vein endothelial cells cultured on native or glycated collagen substrates were stimulated with FGF-2. Plasminogen system activity, cell migration, and capillary-like tube formation were measured, along with plasminogen system protein and mRNA levels. Glycated collagen decreased endothelial cell plasminogen system activity, cell migration, and tube length. FGF-2 did not restore plasminogen system activity or tube formation in cells on glycated collagen, despite decreasing plasminogen activator inhibitor-1 (PAI-1) protein level. We now show that PAI-1 binds to glycated collagen, which may localize PAI-1 to the extracellular matrix. These data suggest that FGF-2 may not restore angiogenic functions in endothelial cells on glycated collagen due to PAI-1 bound to glycated collagen. Glycated collagen decreased endothelial plasminogen activity. FGF-2 increased plasminogen activity in cells on native but not glycated collagen. PAI-1 bound to glycated but not native collagen. FGF-2 decreased total PAI-1 but not PAI-1 bound to glycated collagen. PAI-1 binding to glycated collagen may be more important than total PAI-1.

Abstract
Background Poly(ADP-Ribose) polymerase (PARP) activity has been demonstrated fundamental in many cellular processes, including DNA repair, cell proliferation and differentiation. In particular, PARP activity has been recently found to affect proliferation, migration, and tube formation of human umbilical vein endothelial cells. In recent times, PARP inhibitors have entered in clinical trials to potentiate cancer treatments by preventing DNA repair, but little is known about the effects performed by different drug concentrations on neoangiogenesis, an essential step in tumor growth. Methods Human umbilical vein endothelial cells were treated with 3 aminobenzamide (3ABA), a PARP inhibitor, and tested for several different cellular parameters. Results Here we present in vitro evidence that a low concentration of 3ABA (50 μM), stimulates angiogenesis by decreasing fibrinolytic activity, carried out by urokinase-type plasminogen activator (uPA), and by enhancing matrix metalloprotease-2 (MMP-2) gelatinolytic activity, in fibroblast growth factor-2-stimulated endothelial cells. These unbalanced pathways modify in vitro angiogenic steps, inhibiting chemoinvasion and stimulating tubulogenic activity. Conclusions Our results suggest that the proangiogenic effect of low concentrations of 3ABA alerts on the efficacy of PARP inhibitors to potentiate anticancer therapy. Moreover, they indicate that endothelial chemoinvasion and tubulogenesis depend on distinct proteolytic pathways.

Abstract
Fibrin microthreads are discrete biopolymer fibers, 50-100 μm in diameter, produced from the natural extracellular matrix protein of the provisional matrix that promotes tissue regeneration in the in vivo wound healing environment. The goals of this study were to investigate the feasibility of creating fibrin microthreads containing fibroblast growth factor-2 (FGF-2), and to study the potential of a fibrin matrix to bind signaling proteins known to promote wound healing and regulate cell function in localized cellular microenvironments on scaffold surfaces. FGF-2 was loaded into fibrin microthreads in concentrations ranging from 0 to 200 ng/mL, to investigate the effect of the material on fibroblast attachment, proliferation, cellular outgrowth, and alignment. Although FGF-2-loaded microthreads did not affect fibroblast attachment, they significantly increased cellular outgrowth and proliferation relative to unloaded microthreads. The most pronounced effects were observed at day 7 of cell culture. Further, all of the fibrin microthreads promoted the alignment of fibroblasts and their cytoskeletal components along the long axis of threads, independent of the FGF-2 concentration. Ultimately, we anticipate that these fibrin microthreads will be a promising biopolymer material to promote the regeneration of injured tissues because of their mechanical stability and their matrix signaling capabilities, particularly when loaded with matrix-bound growth factors such as FGF-2.

Abstract
OBJECTIVE Abdominal aortic aneurysm (AAA) development is associated with increased angiogenesis and overexpression of vascular endothelial growth factor (VEGF). Inhibition of angiogenesis results in attenuation of experimental aneurysms. This study investigated the effects of recombinant human (rh)VEGF on experimental aneurysms. METHODS Apolipoprotein E-deficient (apoE(-/-)) mice were assigned to one of four groups: (1) normal saline infusion (sham), (2) angiotensin-II (AngII) infusion, (3) AngII infusion plus 100 microg daily rhVEGF for 14 days (AngII+14dVEGF), or (4) AngII infusion plus 100 microg daily rhVEGF for 21 days (AngII+21dVEGF). Aortic maximum diameter and cross-sectional area were determined by magnetic resonance imaging and microscopy. All mice were sacrificed at day 28. RESULTS Aneurysms developed in all mice in the AngII+14dVEGF and AngII+21dVEGF groups by day 21 compared with 40% in the AngII group. Treatment with rhVEGF increased maximum aortic diameter (P < .002) and cross-sectional area of aneurysms (P < .005) at day 21. This effect was maintained at day 28 (P < .0005). Decreasing rhVEGF treatment from 21 to 14 days did not attenuate aneurysm formation. Treatment with rhVEGF upregulated matrix metalloproteinase 2 gene expression within the aortic wall (P < .0009). CONCLUSIONS Treatment with rhVEGF intensified the formation of AngII-induced aneurysms. Further studies are needed to investigate if antiangiogenic therapy may be a valid medical therapy against aneurysm expansion or rupture.

Abstract
Copper is known to trigger endothelial cells towards angiogenesis. Different approaches have been investigated to develop vascularisation in biomaterials. The angiogenic and healing potential of copper ions in combination with two major angiogenic factors was examined. A 3D culture system in which, under stimulation by FGF-2 and to a lesser degree with VEGF, endothelial cells assembled into structures resembling to an angiogenic process was used. The combination of CuSO(4) with increasing doses of VEGF or FGF-2 enhanced the complexity of angiogenic networks in a significant manner. In vivo studies were also conducted by incorporating FGF-2 with CuSO(4) in a cylindrical collagen-based scaffold. CuSO(4) enhanced significantly the invasion of microvessel compared to control implants and to 20ng FGF-2+/-CuSO(4). Vascular infiltration was also significantly improved by combination of CuSO(4) with FGF-2, compared to FGF-2 alone (0.2 and 1microg). Nevertheless, in comparison with CuSO(4) alone, there was a significant increase only with 1microg of FGF-2 combined with CuSO(4). Significantly, collagen fiber deposition was enhanced following the combinatory loading in comparison to that with FGF-2 alone but not with CuSO(4) only. Thus, copper associated with growth factors may have synergistic effects which are highly attractive in the fields of tissue engineering (e.g., bone) and biomaterials.

Abstract
Fibrin deposition and exudation of plasma fibrinogen (Fg) have long been recognized as hallmarks of inflammation, cardiovascular disease and neoplasia. The Fg-beta(15-42) domain binds to the endothelial cell adhesion molecule, VE-cadherin, promoting endothelial cell proliferation, angiogenesis and leukocyte diapedesis. Furthermore, spontaneous blood-borne and lymphatic metastasis of some types of tumor emboli requires plasma fibrin(ogen); however, the molecular mechanisms by which this occurs are poorly understood. We sought to determine whether Fg-beta(15-42) and VE-cadherin binding interactions promote endothelial barrier permeability and breast cancer cell transendothelial migration (TEM) using transwell insert culture systems. Synthetic peptides containing/missing residues beta(15-17) critical for Fg-beta(15-42) binding to VE-cadherin, and antibodies that bind to Fg-beta(15-21) (T2G1) and VE-cadherin (BV9) were used to induce or inhibit Fg-mediated permeability and TEM. Fg induced dose-dependent permeability of human umbilical vein and microvascular endothelial but not epithelial cell barriers. Maximal Fg-induced endothelial permeability required Fg-beta(15-42) and VE-cadherin-binding interactions involving Fg-beta(15-17). Fg-induced TEM of malignant MDA-MB-231 and MCF-7 breast cancer cells also required Fg-beta(15-42) and VE-cadherin binding; however, such TEM was independent of E-cadherin or estrogen receptor expression. In contrast, Fg did not induce TEM of nonmalignant MCF-10A breast epithelial cells. Fg-induced endothelial permeability was retained in the presence of MDA-MB-231 but inhibited in the presence of MCF-10A cells. It is intriguing to speculate that loss of Fg-beta(15-42) binding by premalignant breast epithelial cells serves as a molecular switch to induce a highly aggressive, metastatic breast cancer phenotype. Hence, Fg-beta(15-42) represents a potential molecular target for therapeutic intervention of breast cancer metastasis.

Abstract
Basic fibroblast growth factor (bFGF) is a potent mitogen in endothelial and vascular smooth muscle cells that increases in serum from adults with coronary artery disease and in microalbuminuric type 2 diabetes mellitus. There has been no prior study of plasma bFGF as a possible cardiovascular risk marker in type 2 diabetes mellitus. In this study, we tested for a correlation between log plasma bFGF immunoreactivity (bFGF-IR) and baseline cardiovascular risk factors in a baseline subset of subjects with advanced type 2 diabetes mellitus from the Veterans Affairs Diabetes Trial ([mean] age, 60 years; hemoglobin A(1c), 9.5%; diabetes' duration, 11 years). Plasma bFGF-IR was determined with a sensitive, specific, 2-site enzyme-linked immunoassay in 281 patients at the baseline visit. Results were compared with baseline risk factors or baseline medication use. Baseline plasma bFGF-IR ranged from 0 to 141 pg/mL. Log plasma bFGF correlated significantly with non-Hispanic white race (P = .002), waist-hip ratio (P = .002), and plasminogen activator inhibitor-1 concentration (P < .0001). Log plasma bFGF correlated inversely with African American race (P = .0003). In multiple regression analysis, plasminogen activator inhibitor-1 and race were significantly correlated with log plasma bFGF. These results suggest a significant correlation between log plasma bFGF-IR and plasminogen activator inhibitor-1, a marker of hemostatic risk.

Abstract
BACKGROUND Fibroblast growth factor (FGF)-2 is a critical growth factor in normal and malignant cell proliferation and tumor-associated angiogenesis. Fibrinogen and fibrin bind to FGF-2 and modulate FGF-2 functions. Furthermore, we have shown that extrahepatic epithelial cells are capable of endogenous production of fibrinogen. OBJECTIVE Herein we examined the role of fibrinogen and FGF-2 interactions on prostate and lung adenocarcinoma cell growth in vitro. METHODS Cell proliferation was measured by (3)H-thymidine uptake and the specificity of FGF-2-fibrinogen interactions was measured using wild-type and mutant FGF-2s, fibrinogen gamma-chain (FGG) RNAi and co-immunoprecipitation. Metabolic labeling, immunopurification and fluorography demonstrated de novo fibrinogen production. RESULTS FGF-2 stimulated DU-145 cell proliferation, whereas neither FGF-2 nor fibrinogen affected the growth of PC-3 or A549 cells. Fibrinogen augmented the proliferative effect of FGF-2 on DU-145 cells. The role of fibrinogen in FGF-2-enhanced DNA synthesis was confirmed using an FGF-2 mutant that exhibits no binding affinity for fibrinogen. FGG transcripts were present in PC-3, A549 and DU-145 cells, but only PC-3 and A549 cells produced detectable levels of intact protein. RNAi-mediated knockdown of FGG expression resulted in decreased production of fibrinogen protein and inhibited (3)H-thymidine uptake in A549 and PC-3 cells by 60%, which was restored by exogenously added fibrinogen. FGF-2 and fibrinogen secreted by the cells were present in the medium as a soluble complex, as determined by coimmunoprecipitation studies. CONCLUSIONS These data indicate that endogenously synthesized fibrinogen promotes the growth of lung and prostate cancer cells through interaction with FGF-2.

Abstract
Skin, the largest organ in the body, protects against toxins and microorganisms in the environment and serves to prevent dehydration of all non-aquatic animals. Immune surveillance, sensory detection, and self-healing are other critical functions of the skin. Loss of skin integrity because of injury or illness may result acutely in substantial physiologic imbalance and ultimately in significant disability or even death. It is estimated that, in 1992, there were 35.2 million cases of significant skin loss (US data) that required major therapeutic intervention. Of these, approximately 7 million wounds become chronic. Regardless of the specific advanced wound care product, the ideal goal would be to regenerate tissues such that both the structural and functional properties of the wounded tissue are restored to the levels before injury. The advent of tissue-engineered skin replacements revolutionized the therapeutic potential for recalcitrant wounds and for wounds that are not amenable to primary closure. This article will introduce the reader to the field of tissue engineering, briefly review tissue-engineered skin replacement from a historical perspective and then review current state-of-the-art concepts from our vantage point.

Abstract
Interstitial flow plays important roles in the morphogenesis, function, and pathogenesis of tissues. To investigate these roles and exploit them for tissue engineering or to overcome barriers to drug delivery, a comprehensive consideration of the interstitial space and how it controls and affects such processes is critical. Here we attempt to review the many physical and mathematical correlations that describe fluid and mass transport in the tissue interstitium; the factors that control and affect them; and the importance of interstitial transport on cell biology, tissue morphogenesis, and tissue engineering. Finally, we end with some discussion of interstitial transport issues in drug delivery, cell mechanobiology, and cell homing toward draining lymphatics.

Abstract
Angiogenesis is a process required not only for embryonal development but is encountered in wound healing and in pathological situations such as tumour growth. In vitro, formation of capillary-like structures can be induced by seeding human microvascular endothelial cells (HDMECs) on top of a fibrin matrix in the presence of phorbol 12-myristate 13-acetate (PMA) as a stimulating agent. In this study, we show that supernatants collected from high-invasive melanoma cells (BLM) induce the formation of tubular structures similar to PMA treatment whereas supernatants from low-invasive cells (WM164) did not. Analysis of proteins secreted into the supernatant of both melanoma cell lines identified differential expression of several pro-angiogenic proteins in high- and low-invasive melanoma cells. Vascular endothelial growth factor (VEGF) was strongly expressed by high- but not by low-invasive melanoma cells. Neutralisation of VEGF as well as inhibition of matrix metalloproteases (MMPs) using the broad spectrum MMP inhibitor 1,10-phenanthroline, both strongly reduced the melanoma-induced tube formation. PMA treatment of HDMECs on a fibrin matrix stimulated MT1-MMP synthesis, indicating that this protease is involved in PMA-induced angiogenesis. In addition, stimulation of HDMECs by supernatants of BLM melanoma cells resulted in a strong induction of ADAM-15, which is known to act as a metalloproteinase. In conclusion, these results show that VEGF released by melanoma cells is an important mediator of neo-vascularisation and that this process depends on the presence of metalloproteinases.

Abstract
Angiogenesis plays a key role in various physiological and pathological processes, including inflammation and tumor growth. Numerous angiogenic growth factors (AGFs) have been identified. Usually, the angiogenic process is assumed to represent the outcome of a straightforward interaction of AGFs with specific signalling receptors of the endothelial cell (EC) surface. Actually, the mechanisms by which AGFs induce neovascularization are much more complex. Indeed, angiogenesis is the result of the simultaneous actions of various AGFs and angiogenesis modulators; multiple EC surface receptors with different structure and biological properties are engaged by AGFs to exert a full angiogenic response; AGFs bind a variety of free and immobilized proteins, polysaccharides, and complex lipids of the extracellular milieu that affect AGF integrity, stability, and bioavailability; some of the AGF-binding molecules interact also with AGF receptors. In this review the authors summarize literature data and discuss the current knowledge about the extracellular molecules able to interact with AGFs, thus representing possible key regulators of the angiogenesis process and targets/templates for the development of novel antiangiogenic drugs. This work represents an attempt to highlight common theme in the AGF interactome that occurs at the extracellular level during neovascularization.

Abstract
Cell response to extracellular cues is often driven by gradients of morphogenetic and chemotactic proteins, and therefore descriptions of how such gradients arise are critical to understanding and manipulating these processes. Many of these proteins are secreted in matrix-binding form to be subsequently released proteolytically, and here we explore how this feature, along with small dynamic forces that are present in all tissues, can affect pericellular protein gradients. We demonstrate that 1), pericellular gradients of cell-secreted proteins can be greatly amplified when secreted by the cell in matrix-binding form as compared to a nonmatrix-interacting form; and 2), subtle flows can drive significant asymmetry in pericellular protein concentrations and create transcellular gradients that increase in the direction of flow. This study thus demonstrates how convection and matrix-binding, both physiological characteristics, combine to allow cells to create their own autologous chemotactic gradients that may drive, for example, tumor cells and immune cells into draining lymphatic capillaries.

Abstract
We have shown previously that fibrin(ogen) binds fibroblast growth factor 2 (FGF-2) and potentiates stimulation of endothelial-cell (EC) proliferation. We have now used 2 FGF-2 mutants differing only in the 5 residues constituting the binding site to characterize the importance of this interaction in angiogenesis. The nonbinding (2212) and binding (221*2) mutants stimulated EC proliferation by 2.2 +/- 0.4-fold and 2.9 +/- 0.3-fold over control, respectively, and both were similar to wild-type (wt) FGF-2 (2.5 +/- 0.3-fold). Proliferation was augmented by fibrinogen to 5.3 +/- 1.2-fold and 4.8 +/- 0.8-fold with wtFGF-2 and 221*2, whereas no augmentation occurred with 2212 and fibrinogen. Using a placental explant model in a fibrin matrix, wtFGF-2 resulted in 2.6 +/- 0.9-fold more growth over control, and 221*2 increased growth 3.3 plus or minus 0.9-fold. Vessel outgrowth with 2212 was minimal and comparable to control. Similarly, fibrinogen potentiated wtFGF-2 or 221*2-mediated angiogenesis in the chicken chorioallantoic membrane model. In a mouse Matrigel implant model, fibrinogen significantly increased angiogenesis with either wtFGF-2 or 221*2, whereas there was no augmentation with 2212. These results demonstrate that binding of FGF-2 to fibrin(ogen) mediated by the 5-residue FGF-2-fibrin(ogen) interactive site is required for augmented angiogenesis.

Abstract
Fibroblast growth factors (FGFs) are a family of heparin-binding growth factors. FGFs exert their pro-angiogenic activity by interacting with various endothelial cell surface receptors, including tyrosine kinase receptors, heparan-sulfate proteoglycans, and integrins. Their activity is modulated by a variety of free and extracellular matrix-associated molecules. Also, the cross-talk among FGFs, vascular endothelial growth factors (VEGFs), and inflammatory cytokines/chemokines may play a role in the modulation of blood vessel growth in different pathological conditions, including cancer. Indeed, several experimental evidences point to a role for FGFs in tumor growth and angiogenesis. This review will focus on the relevance of the FGF/FGF receptor system in adult angiogenesis and its contribution to tumor vascularization.
