From: In renal cell carcinoma the PTEN splice variant PTEN-Δ shows similar function as the tumor suppressor PTEN itself

Influence of PTEN-Δ and PTEN on the functional behavior of renal tumor cells. a Migration of PTEN-Δ or PTEN transfected 786-O and A498 cells was determined in a Boyden chamber using ECM compounds as chemotaxins (FN: Fibronectin, VN: Vitronectin, LM: Laminin, CI: Collagen I and CIV: Collagen IV). Differences are shown in percentage of control cells (pcDNA3 transfected cells). b Cell adhesion of PTEN-Δ or PTEN transfected 786-O and A498 cells on immobilized ECM compounds were determined. BSA was used as control (Data not shown). Differences are shown in percentage of control cells (pcDNA3 transfected cells). c Apoptosis values of PTEN-Δ or PTEN transfected 786-O and A498 cells were quantified by determination of cytoplasmic histone-associated DNA fragments (Cell death detection assay, Roche). Differences are shown in percentage of control cells (pcDNA3 transfected cells). Significance was calculated by Student‘s T-test, *p < 0.05
