RATIONALE Angiogenic hypersprouting and leaky vessels are essential for tumor growth. MicroRNAs have unique therapeutic advantages by targeting multiple pathways of tumor-associated angiogenesis, but the function of individual miRNAs of miR302-367 cluster in angiogenesis and tumors has not yet been fully evaluated. OBJECTIVE To investigate the functions of miR302-367 in developmental angiogen...
Angiogenesis and invasion are essential processes for solid tumor growth and dissemination. The tumor development process can be dependent on the activation of a series of signaling pathways, including growth factor-activated pathways. MicroRNAs have been shown to be critical for tumorigenesis, but their roles in cancer angiogenesis, invasion and other signaling pathways important for tumor dev...
The role of B cells in cancer and the underlying mechanisms remain to be further explored. Here, we show that tumor-associated B cells with activated STAT3 contribute to tumor development by promoting tumor angiogenesis. B cells with or without Stat3 have opposite effects on tumor growth and tumor angiogenesis in both B16 melanoma and Lewis Lung Cancer mouse models. Ex vivo angiogenesis assays ...
Tumor angiogenesis requires intricate regulation of gene expression in endothelial cells. We recently showed that DNA methyltransferase (DNMT) and histone deacetylase (HDAC) inhibitors directly repress endothelial cell growth and tumor angiogenesis, suggesting that epigenetic modifications mediated by DNMTs and HDAC are involved in regulation of endothelial cell gene expression during tumor ang...
Angiogenesis is crucial for tumor growth. Thus, inhibiting angiogenesis represents a promising avenue for preventing tumor growth. This study investigated the anti-angiogenesis and anti-tumor effects of 8-hydroxyquinoline ruthenium(II) complexes [Ru(bpy)2(8-HQ)](+) (BQ) and [Ru(phen)2(8-HQ)](+) (PQ). The results showed that both compounds, especially PQ, suppressed the proliferation, migration,...
Angiotensin II is a multi-functional bioactive peptide and recent reports have suggested that angiotensin II is a proangiogenic growth factor. A retrospective cohort study revealed that angiotensin converting enzyme inhibitors decreased cancer risk, however, the precise mechanism is unknown. We hypothesized that endogenous angiotensin II plays a crucial role in tumor-associated angiogenesis. Tu...
Bv8 (prokineticin 2) expressed by Gr1(+)CD11b(+) myeloid cells is critical for VEGF-independent tumor angiogenesis. Although granulocyte colony-stimulating factor (G-CSF) has been shown to be a key inducer of Bv8 expression, the basis for Bv8 production in driving tumor angiogenesis is undefined. Because the cell adhesion molecule CEACAM1, which is highly expressed on Gr1(+)CD11b(+) myeloid cel...
