Description & Mechanism
Vesugen (KED) is studied in vitro as a vascular / endothelium-directed short-peptide probe. In organotypic and dissociated cell cultures it has been reported to stimulate the proliferation marker Ki-67 and to reduce apoptosis (decreased p53), used experimentally to study endothelial cell proliferation and vascular-tissue gene-expression programmes.
It is a tool for probing chromatin-level transcriptional regulation in vascular and neuroimmunoendocrine cell systems. Observed effects depend on concentration, model system and exposure conditions.
Applications in Research
- In-vitro endothelial / vascular cell proliferation and apoptosis-marker studies
- Neuroimmunoendocrine organotypic-culture gene-expression research
- Reference probe for short-peptide transcriptional regulation
