YBX1 and lung adenocarcinoma: In addition, we analyzed the expression of YBX1 and MUC1 in HLF cell and five lung adenocarcinoma cell lines (H358, HCC827, A549, H322, H1299) (Figures 1C, D), and they were significantly correlated at both the protein (Figure 1C, r=0.8789, p=0.0057) and mRNA (Figure 1D, r=0.9306, p=0.0018) levels.
