Functieomschrijving

Background:
Cellular senescence is a complex tumor-suppressive mechanism induced by many different stresses. Senescent cells are characterized by growth arrest, changes in morphology and gene expression, and the secretion of inflammatory cytokines, proteases and other molecules that can alter the tissue microenvironment (a phenomenon termed the senescence-associated secretory phenotype or SASP). For an unknown mechanism, senescent cells increase with age, and are evident at sites of numerous age-related pathologies and pre-cancerous lesions. Recent results show that life-long elimination of senescent cells can prevent the development of certain age-related pathologies in a mouse model of segmental accelerated aging, strongly supporting the idea that senescent cells can be deleterious. In contrast, we and others have shown that the SASP might have a beneficial effect during tissue repair by promoting collagen degradation and differentiation of myofibroblasts. Thus, there is the possibility that senescence has been selected to ensure early life fitness (wound healing), but may have unselected deleterious effects late in life (aging and cancer promotion).

The Demaria lab is interested to dissect the molecular phenotypes of cellular senescence induced by different stimuli, and to characterize how they can promote age-related cancers.
The proposed project aims to determine how senescent cells are accumulated upon UV radiation, and the contribution of UV-induced senescence for melanoma progression. More in the specific, we will use different mouse models, mouse and human primary cells and human biopsies. We will evaluate the induction and the behaviour of senescent cells induced by UV, and their pro-tumorigenic phenotype in relation to melanoma. Moreover, we will screen and test different compounds with the potential of specifically eliminate senescent cells in vivo. You will study gene expression, cellular interactions, immune cell activation, melanomagenesis, tumor progression, drug actions and phenotypic effects.
