Figure 2From: Increased plasma membrane cholesterol in cystic fibrosis cells correlates with CFTR genotype and depends on de novo cholesterol synthesisElectrochemical determination of membrane cholesterol content in CFTR corrected CF cells. A) Representative traces of membrane cholesterol determination in IB3 CF cells and in CFTR-corrected IB3 cells (S9). B) Quantification of responses between IB3 and S9 cells. Responses are reported relative to wt response (response ratio) to indicate the fold-increase in response. Error bars represent SEM, n = 4 for each. Significance determined by t test. *p < 0.001.Back to article page
