PAK2 and non-small cell lung carcinoma: By exploring non-small cell lung cancer (NSCLC) patient, the expression of NapsinA and cytokeratin5 exhibited concordant pattern between IHC and RPPA and upon profiling 150 protein expression using RPPA, researchers discovered elevated expression of PAK2 in squamous carcinoma compared to adanocacinoma indicating its potential role during tumorigenesis20.
