Cytoplasmic p21(CIP1/WAF1), ERK1/2 activation, and cytoskeletal remodeling are associated with the senescence-like phenotype after airborne particulate matter (PM(10)) exposure in lung cells.

Abstract excerpt

The exposure to particulate matter with a mean aerodynamic diameter ≤10 μm (PM10) from urban zones is considered to be a risk factor in the development of cancer. The aim of this work was to determine if PM10 exposure induces factors related to the acquisition of a neoplastic phenotype, such as cytoskeletal remodeling, changes in the subcellular localization of p21(CIP1/WAF1), an increase in β-galactosidase...
