What is the background of the project?
Disorders of platelet aggregation occur frequently in the context of ageing and age-related diseases such as cancer. While the functional connections between cancer cells and platelets have been well documented, little is known about the effects of senescent cells on platelet activation. Cellular senescence is a form of stable cell cycle arrest that is triggered by a variety of stimuli. Interestingly, in spite of their inability to proliferate, senescent cells are able to produce and secrete a plethora of factors that may promote extracellular matrix remodeling, or even stimulate proliferation of neighboring cells. Thus far, however, the effects of this Senescence-Associated Secretory Phenotype (SASP) on platelet function have not been explored. We surmise that components of the SASP might be able to modulate platelet function. What is the aim of the project? To determine the effect of factors secreted by senescent cells on platelet activity. What techniques and methods are used. Mention the steps/stages in this project? • Cell biology: tissue culture experiments, immunofluorescence, beta-Galactosidase staining (induction of senescence in vitro) • Molecular biology: Quantitative PCR (determination of SASP expression) • Platelet aggregation experiments (determination of the effect of SASP factors on platelets)
