A glycolytic mechanism regulating an angiogenic switch in prostate cancer.
The generation of an "angiogenic switch" is essential for tumor growth, yet its regulation is poorly understood. In this investigation, we explored the linkage between metastasis and angiogenesis through CXCL12/CXCR4 signaling. We found that CXCR4 regulates the expression and secretion of the glycolytic enzyme phosphoglycerate kinase 1 (PGK1). Overexpression of PGK1 reduced the secretion of vas...
متن کاملTargeting the angiogenic 'splice' switch; inhibition of SRPK1 as a novel therapeutic approach in prostate cancer
Pathological angiogenesis occurs when the balance between pro-angiogenic and anti-angiogenic factors is tipped enabling an angiogenic switch. VEGF-A is the primary inducer of angiogenesis but is alternatively spliced at the pre-mRNA level to produce pro-angiogenic and anti-angiogenic isoforms. In previous work we showed that the balance of VEGF-A isoforms is regulated by SRSF1, which is regulat...
متن کاملEvolution of uncontrolled proliferation and the angiogenic switch in cancer.
The major goal of evolutionary oncology is to explain how malignant traits evolve to become cancer ``hallmarks." One such hallmark---the angiogenic switch---is difficult to explain for the same reason altruism is difficult to explain. An angiogenic clone is vulnerable to ``cheater" lineages that shunt energy from angiogenesis to proliferation, allowing the cheater to outcompete cooperative phen...
متن کاملTranscriptional network governing the angiogenic switch in human pancreatic cancer.
A shift of the angiogenic balance to the proangiogenic state, termed the "angiogenic switch," is a hallmark of cancer progression. Here we devise a strategy for identifying genetic participants of the angiogenic switch based on inverse regulation of genes in human endothelial cells in response to key endogenous pro- and antiangiogenic proteins. This approach reveals a global network pattern for...
متن کاملTumor-associated macrophages press the angiogenic switch in breast cancer.
The development of a supportive vasculature is essential for tumor progression. In a mouse model of breast cancer, we found that tumor-associated macrophages that are recruited to the tumor just before malignant conversion are essential for the angiogenic switch. These findings establish a causal linkage to explain well-documented clinical correlations between macrophages, microvessel density, ...
