Abstract
Mannoproteins (MPs) are a major component of yeast cell walls and consist of high levels of mannose in covalent complexes with proteins. MPs complexly enhance the immune system. We previously isolated a mutant yeast, K48L3, with a higher yield of MP from its cell wall than wild-type Saccharomyces cerevisiae, YPH499. We determined that K48L3 induces the release of nitric oxide in macrophage cells. The present study reports nitric-oxide-mediated angiogenesis by MP from K48L3 and the induction of the Akt/eNOS signal pathway. Western blotting and RT-PCR were used to demonstrate that MP treatment resulted in the upregulation of p-Akt, p-eNOS, and angiogenesis-mediated gene expression. Moreover, the angiogenesis activity of the MPs was demonstrated using three angiogenesis assays, namely, a cell migration assay, a tube-forming assay, and an ex vivo aorta ring assay. Thus, this study demonstrates for the first time that MPs from S. cerevisiae K48L3 induce angiogenesis in HUVECs via the Akt-eNOS-dependent signaling pathway.
