Down-regulation of aquaporin3 expression by lipopolysaccharide via p38/c-Jun N-terminal kinase signalling pathway in HT-29 human colon epithelial cells

Figure 1 Immunocytochemical localisation of aquaporin 3 in HT-29 cells. Aquaporin 3 (AQP3) expression in untreated HT-29 cells (left) or cells treated with 20 μg/mL lipopolysaccharide for 12 h (right). Cells were fixed and analysed by immunofluorescence staining for AQP3 protein using FITC-labelled secondary antibody (magnification × 400).
