PHLPP2 and cancer: In light of the existing reports that p63α, PTEN, PHLPP1 and PHLPP2 are key regulators of cell transformation and cancer cell proliferation [7, 14, 25, 33–35], we investigated the expression levels of these proteins in UROtsa(SNHG1) vs. UROtsa(Vector) cells and in U5637(shSNHG1) vs. U5637(Nonsense) cells and in T24T(shSNHG1) vs. T24T(Nonsense) cells.
