Analysis of expression of PTEN/PI3Â K pathway and programmed cell death ligand 1 (PD-L1) in malignant pleural mesothelioma (MPM)

This study shows PTEN/PI3 K pathway and PD-L1 in MPM are frequently activated. Our results suggests that there is not association between PD-L1 and the involvement of the PI3 K pathway in MPM.
