GLUT3 is strongly expressed in mesenchymal lung tumor cells. (A) The indicated cell lines were lysed for RNA preparation followed by reverse transcription. The cDNA was amplified by real-time PCR using probes specific for the indicated genes or internal controls. Data show means ± s.d. (n = 3) of mRNA or mature microRNA expression relative to the cell line expressing the least amount of the same gene (set to 1). (B) The indicated cells were stained to analyze the expression of GLUT3 or E-cadherin by immunocytochemistry. Scale bar, 100 μm. In (A) and (B), the dashed line indicates the separation between the mesenchymal and the epithelial groups of cells.
