[PMID: 33082325 PMCID: PMC7575565 DOI: 10.1038/s41419-020-03096-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2020] [Revised: 09/08/2020] [Accepted: 09/11/2020] [Indexed: 12/22/2022]
Abstract
Ring finger protein 180 (RNF180) is an important member of the E3 ubiquitin ligase family. As a tumor suppressor gene, RNF180 is significantly associated with the prognosis of patients with gastric cancer (GC) and can inhibit the proliferation, invasion, and migration of GC cells. Signal transducer and activator of transcription 3 (STAT3) are considered one of the most common oncogenes in human cancers with a key role in GC progression. In this study, we explored the molecular signaling pathways by which RNF180 could potentially regulate STAT3 through transcriptomics and proteomics experiments. Here, we found RNF180 overexpression could suppress STAT3 phosphorylation in GC cells. Ubiquitin label-free experiments showed that the ubiquitination level of Ras homolog gene family member C (RhoC) is significantly increased in GC cells transfected with an RNF180 expression vector (RNF180-GFP vector) compared with cells transfected with an empty vector (vehicle vector). We subsequently demonstrated that RNF180 could directly combine with RhoC and promote the ubiquitination and degradation of RhoC protein in GC cells. The phosphorylation level of STAT3 significantly decreased in GC cells after RhoC knockdown using small hairpin RNA (shRNA). Together, these results reveal RNF180 could inhibit GC progression by reducing the phosphorylation of STAT3 via the ubiquitination and degradation of RhoC protein in GC cells. Thus, the protein may be considered a novel therapeutic target for patients with GC.

Abstract
Background Glioblastoma ranks among the most lethal cancers, with current therapies offering only palliation. Paracrine vascular endothelial growth factor (VEGF) signaling has been targeted using anti-angiogenic agents, whereas autocrine VEGF/VEGF receptor 2 (VEGFR2) signaling is poorly understood. Bevacizumab resistance of VEGFR2-expressing glioblastoma cells prompted interrogation of autocrine VEGF-C/VEGFR2 signaling in glioblastoma. Methods Autocrine VEGF-C/VEGFR2 signaling was functionally investigated using RNA interference and exogenous ligands in patient-derived xenograft lines and primary glioblastoma cell cultures in vitro and in vivo. VEGF-C expression and interaction with VEGFR2 in a matched pre- and post-bevacizumab treatment cohort were analyzed by immunohistochemistry and proximity ligation assay. Results VEGF-C was expressed by patient-derived xenograft glioblastoma lines, primary cells, and matched surgical specimens before and after bevacizumab treatment. VEGF-C activated autocrine VEGFR2 signaling to promote cell survival, whereas targeting VEGF-C expression reprogrammed cellular transcription to attenuate survival and cell cycle progression. Supporting potential translational significance, targeting VEGF-C impaired tumor growth in vivo, with superiority to bevacizumab treatment. Conclusions Our results demonstrate VEGF-C serves as both a paracrine and an autocrine pro-survival cytokine in glioblastoma, promoting tumor cell survival and tumorigenesis. VEGF-C permits sustained VEGFR2 activation and tumor growth, where its inhibition appears superior to bevacizumab therapy in improving tumor control.

Primary Tumor-Secreted Lymphangiogenic Factors Induce Pre-Metastatic Lymphvascular Niche Formation at Sentinel Lymph Nodes in Oral Squamous Cell Carcinoma. PLoS One 2015; 10:e0144056. [PMID: 26630663 PMCID: PMC4668078 DOI: 10.1371/journal.pone.0144056] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2015] [Accepted: 11/12/2015] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVES The objectives of this study were to evaluate the formation of lymphvascular niches in lymph nodes of patients with oral squamous cell carcinoma (OSCC), and investigate the roles of lymphangiogenic and angiogenic factors, such as vascular endothelial growth factor (VEGF)-A, VEGF-C, and VEGF-D, expressed in the primary tumors. MATERIALS AND METHODS Forty-four patients with previously untreated clinically late T2 or T3 OSCC of cN0 were evaluated for primary tumors and 166 sentinel lymph nodes (SLNs). Primary tumors were immunohistochemically analyzed for expressions of VEGFs. Densities of lymphatic vessels (LVDpodoplanin) and high endothelial venules (HEVD) in the SLNs were also calculated using antibodies for each marker, podoplanin and MECA-79, respectively. RESULTS In 25 patients, all lymph nodes were metastasis-negative, whereas, in 19 patients, metastasis was positive for at least one lymph node (either at SLN, non-SLN, or nodal recurrence). From the analyses of 140 SLNs without metastasis, LVDpodoplanin in 50 SLNs of metastasis-positive cases was significantly higher than that in 90 SLNs of metastasis-negative cases (p = 0.0025). HEVD was not associated with lymph node metastasis. The patients with VEGF-A-High or VEGF-D-High tumors had significantly higher LVDpodoplanin than patients with their Low counterparts (p = 0.0233 and p = 0.0209, respectively). In cases with lymph node metastasis, the VEGF-D-expression score was significantly higher than in those without lymph node metastasis (p = 0.0006). CONCLUSIONS These results suggest that lymph node lymphangiogenesis occurs before metastasis in OSCC. VEGF-A and VEGF-D play critical roles in this process. VEGF-D is a potential predictive marker of positive lymph node metastasis in cN0 patients.

Combining the multitargeted tyrosine kinase inhibitor vandetanib with the antiestrogen fulvestrant enhances its antitumor effect in non-small cell lung cancer. J Thorac Oncol 2012; 7:485-95.

Abstract
INTRODUCTION Estrogen is known to promote proliferation and to activate the epidermal growth factor receptor (EGFR) in non-small cell lung cancer (NSCLC). Vascular endothelial growth factor (VEGF) is a known estrogen responsive gene in breast cancer. We sought to determine whether the VEGF pathway is also regulated by estrogen in lung cancer cells, and whether combining an inhibitor of the ER pathway with a dual vascular endothelial growth factor receptor (VEGFR)/EGFR inhibitor would show enhanced antitumor effects. METHODS We examined activation of EGFR and expression of VEGF in response to β-estradiol, and the antitumor activity of the multitargeted VEGFR/EGFR/RET inhibitor, vandetanib, when combined with the antiestrogen fulvestrant both in vitro and in vivo. RESULTS NSCLC cells expressed VEGFR-3 and EGFR. Vandetanib treatment of NSCLC cells resulted in inhibition of EGFR and VEGFR-3 and inhibition of β-estradiol-induced P-MAPK activation, demonstrating that vandetanib blocks β-estradiol-induced EGFR signaling. Treatment with β-estradiol stimulated VEGFA mRNA and protein (p < 0.0001 over baseline), suggesting estrogenic signaling causes heightened VEGFA pathway activation. This estrogenic induction of VEGFA mRNA seems largely dependent on cross-talk with EGFR. Long-term vandetanib treatment also significantly increased ERβ protein expression. The combination of vandetanib with fulvestrant maximally inhibited cell growth compared with single agents (p < 0.0001) and decreased tumor xenograft volume by 64%, compared with 51% for vandetanib (p < 0.05) and 23% for fulvestrant (p < 0.005). Antitumor effects of combination therapy were accompanied by a significant increase in apoptotic cells compared with single agents. CONCLUSIONS Fulvestrant may enhance effects of vandetanib in NSCLC by blocking estrogen-driven activation of the EGFR pathway.

Abstract
The malignancy of tumors depends on the biomechanical properties of cancer cells and their microenvironment, which enable cancer cells to migrate through the connective tissue, transmigrate through basement membranes and endothelial monolayers and form metastases in targeted organs. The current focus of cancer research is still based on biological capabilities such as molecular genetics and gene signaling, but these approaches ignore the mechanical nature of the invasion process of cancer cells. This review will focus on how structural, biochemical and mechanical properties of extracellular matrices (ECMs), and adjacent cells regulate the invasiveness of cancer cells. In addition, it presents how cancer cells create their own microenvironment by restructuring of the ECM and by interaction with stromal cells, which then further contribute to the progression of cancer disease. Finally, this review will point out that mechanical properties are a critical determinant for the efficiency of cancer cell invasion and the progression of cancer which might affect the future development of new cancer treatments.

Abstract
Lymph node metastasis is a major prognostic factor for patients with gallbladder cancer (GBC), and greater understanding of the molecule mechanism of lymph node metastasis in GBC is needed to improve prognosis. VEGF-D has been implicated in the control of lymphangiogenesis in many carcinomas, but the biological function of VEGF-D in human GBC remains unclear. In this study, we analyzed the role of the VEGF-D in human GBC cells and addressed the functional role of VEGF-D using a xenograft mouse model. We examined the expression of VEGF-D in three human gallbladder cancer cell lines. A lentivirus-based effective VEGF-D siRNA vector was infected into GBC NOZ cells. The effect of VEGF-D siRNA on GBC NOZ cells was investigated by cell proliferation assay and invasion assay. Furthermore, we examined the role of VEGF-D-SiRNA on GBC NOZ cells in the mice of subcutaneous and orthotopic xenograft tumor. Our results are as follows: VEGF-D mRNA and protein were expressed in all three GBC cell lines (GBC-SD, NOZ, and SGC-996). We successfully selected D-3/siRNA as the most effective siRNA to silence VEGF-D expression after four VEGF-D siRNA plasmid transfection in NOZ cells. VEGF-D mRNA and protein expression were suppressed by lentivirus-mediated D-3/siRNA. D-3-RNAi-LV inhibited NOZ cells proliferation and invasion ability in vitro. D-3-RNAi-LV inhibited tumor growth and lymphangiogenesis in the NOZ cell subcutaneous xenograft model. D-3-RNAi-LV inhibited lymphangiogenesis and lymphatic metastasis in the NOZ cell orthotopic xenograft model. Furthermore, D-3-RNAi-LV inhibited tumor ascites and hepatic invasion in the NOZ cell orthotopic xenograft model. In conclusion, VEGF-D is involved and plays an important role in GBC progression, suggesting that VEGF-D may be a potential molecular target in the treatment of GBC.

Abstract
Digestive tumors account for a large portion of human malignancies, and their incidence and mortality are on the rise. Neovascularization plays a critical role in the metastasis of tumors. Vascular endothelial growth factor (VEGF) is one of the best characterized angiogenic regulators. There is close relationship between VEGF and tumor growth, invasion and metastasis. VEGF has become a research hot for diagnosis, targeted therapy and prognosis of tumors. The purpose of this review is to review the recent progress in understanding the relationship between VEGF and digestive tumors.

Abstract
The purpose of this study was to evaluate the association between the expression of growth factors and the clinicopathological variables of colorectal adenocarcinoma. Immunohistochemistry and fluorescence in situ hybridization (FISH) were used to evaluate the amplification and expression of epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), VEGF-D, VEGF receptor (VEGFR)-2, VEGFR-3, transforming growth factor (TGF)-β1, and insulin-like growth factor-1 receptor (IGF-1R) in a tissue microarray of 292 colorectal adenocarcinomas. The expression of EGFR, VEGF, VEGF-D, VEGFR-2 and VEGFR-3 was detected in 5.1%, 10.0%, 6.8%, 5.2%, and 57.2%. EGFR expression was associated with angioinvasion (p < 0.05) and lymph node metastasis (p < 0.005). VEGFR-3 expression was higher in the rectum than in the colon (p < 0.05). VEGF expression correlated with VEGF-D (p < 0.05) and VEGFR-3 (p < 0.005) expression, while VEGF-D expression showed no significant association with VEGFR-2 or VEGFR-3. EGFR amplification was present in 10.6% and was not associated with EGFR protein expression. VEGFR-2 and VEGFR-3 expression levels were related to poor patient survival. Stage, perineural invasion, and lymph node metastasis were independent prognostic factors based on a Cox analysis. VEGFR-2 and VEGFR-3 expression are markers of a poor prognosis in patients with surgically resected colorectal adenocarcinoma, whereas EGFR has a minor influence.

Abstract
BACKGROUND Kawasaki disease (KD) is characterized by systemic vasculitis with tissue edema. During the healing process of inflammation, lymphangiogenesis is essential for reducing tissue edema. One potential responsible candidate for the induction of lymphangiogenesis in the healing process of acute KD is vascular endothelial growth factor-D (VEGF-D). METHODS AND RESULTS Sequential changes in serum VEGF-D levels in patients with acute KD (n = 47) using an enzyme-linked immunosorbent assay were investigated. Cross-sectional areas of lymphatic vessels and VEGF-D protein expression were evaluated immunohistochemically in cardiac tissues of patients (n = 6) who died of KD. Regulation of VEGF-D messenger RNA (mRNA) expression in cultured fibroblasts was assessed using quantitative real-time polymerase chain reaction. Serum VEGF-D levels increased after intravenous immunoglobulin therapy in patients with acute KD (P < 0.001). In addition, they were significantly lower in patients with coronary artery lesions (CAL) than in those without CAL (P < 0.05). The cross-sectional areas of lymphatic vessels in cardiac tissues were enlarged in patients with acute KD. VEGF-D protein was detected on the endothelium of the enlarged lymphatic vessels. In vitro, tumor necrosis factor- significantly down-regulated VEGF-D mRNA expression in cultured fibroblasts (P = 0.004). CONCLUSIONS This study indicates that the production of VEGF-D increases and is related to lymphangiogenesis in patients with acute KD. In addition, low VEGF-D production appears to be associated with the development of CAL.
