Disruption of a single Pten allele augments the chemotactic response of B lymphocytes to stromal cell-derived factor-1.

Abstract excerpt

The tumor suppressor, Pten, has emerged as a critical negative regulator of phosphatidylinositol-3-kinase-dependent intracellular signaling pathways responsible for phenomena such as cellular adhesion, proliferation, and apoptosis. Herein, we present evidence that Pten regulates chemokine-dependent events in B lymphocytes. Primary B cells isolated from Pten(+/-) mice demonstrated increased responsiveness to...
