Abstract

The vascular system transmits and distributes hematopoietic cells, nutrients, gases and chemical mediators of angiogenesis, and participates in tumor development by providing oxygen and nutrients to cancer cells, promoting the formation of new vessels, which stimulate cancer growth and metastasis. Platelets are produced by hematopoietic cells in the bone marrow and play a role in angiogenesis through the storage transport and release of factors that regulate blood vessels growth. Another important function of the platelets is to initiate the repair of injured tissues by regulatory stimuli of platelet-platelet adhesion and platelet-endothelium. Microtubules, actin and protein Rho GTPase for RhoA are essential structural components in the biogenesis of platelets, participating in the formation of proplatelets. ARHGAP21 is a cell adhesion protein, which regulates actin, tubulin, controls the vesicular traffic in membranes of the Golgi complex and presents a possible role in tumor progression. Studies have reported that ARHGAP21 inhibition alters gene expression of endothelial cells and increases RhoA activity. Thus, the aim of this study is to analyze the role of ARHGAP21 protein in processes such as platelet formation and angiogenesis. Cell lines and primary cells from ARHAGAP21 knockout mice generated in our laboratory will be used.
