NUCLEOLIN and non-small cell lung carcinoma: This assessment was further extended to cell lines presenting higher levels of basal p-Akt (ratio p-Akt/total Akt equal or higher than 1), as the non-small cell lung cancer (NSCLC) A549 and H1975 cells (Figure S1), described to overexpress nucleolin and to bind and internalize pegylated pH-sensitive liposomes functionalized with the F3 peptide [25].
