Figure 7. Real time PCR detection of the gene expression of membrane transport proteins of HCE cells at passage 101. Positive gene expression patterns of various membrane transport proteins of HCE cells were shown. AQP1, human aquaporin 1 gene; ATP1A1, human α1 polypeptide of Na+/K+-ATPase gene; VDAC, human voltage-dependent anion channel gene; CLC, human chloride channel protein gene; NBC1, human sodium bicarbonate cotransporter 4 gene; CFTR, human cystic fibrosis transmembrane conductance regulator gene. The housekeeping gene, human glyceraldehyde-3-phosphate dehydrogenase (GAPDH), was used as an internal control.
