Expression of known AT1 cell markers in rat microarray data. Log2 expression data were generated from microarray experiments: AT1-like cells differentiated in culture ( blue ) (Day 2-6), freshly isolated AT1 cells ( purple ), freshly isolated AT2 cells ( red ), and other tissues ( black ). Table at bottom right includes previously described AT1 cell–specific genes, their associated Illumina Probe IDs, and their FDR-corrected P values in this study. FDR adjustment is based on the number of tests shown for known genes.

B) Transepithelial resistance as measured in kΩ-cm 2 over the course of differentiation. Error bars represent technical duplicates for each plating. C) Rat Aqp5 -luciferase 4.3 kb promoter construct. Grey lines = 34 putative PPARA:RXR binding sites (Explain3.0). No sites were predicted from −900 to +6 bp due to lack of rat sequence information in the Explain v3.0 database. The asterisk marks the approximate location in the promoter of the ChIPed RXR site in E, below. The average number of PPARA:RXR sites per kilobase in the listed human/rat/mouse promoters is given in the table, with consensus site listed at the top. D) MLE-15 cells were transiently transfected with the Aqp5 -luciferase construct and treated for 48 hours with vehicle (DMSO) or 7.5 µM UVI-3003. UV1-3003 treatment reduced Aqp5 -luc activity by 48%±0.06. Values were normalized to vehicle control and represent the mean, error bars represent SEM, N = 3. All experiments represent 3 biological replicates. E) ChIP was performed on primary cultured rat AEC at day 0 (AT2, D0, n = 2) and day 8 (AT1-like, D8, n = 3). A region ∼4 kb upstream of the transcription start site specifically precipitated with RXR in day 8 samples. ChIP of GAPDH with RXR was performed as a control, and POL2 (POLR2A) binding to the GAPDH promoter was included as a positive control for the quality of day 0 DNA.

Immunohistochemistry and TUNEL assay of salivary glands at 12 weeks post-RI treatment. Representative immunohistochemical images show salivary epithelial cells (aquaporins 5 (AQP5) staining) and myoepithelial cells (α-smooth muscle actin (α-SMA) staining). The expression level of AQP5 and α-SMA was lower in the radioiodine-exposed group (RI group) than in the normal group. Treatment with fucoidan increased the staining intensity of these cells relative to the RI group. The total number of TUNEL-positive cells was significantly reduced in the fucoidan group as compared with the RI group at 2, 4, and 12 weeks post RI. Statistical analyses were conducted using the Kruskal-Wallis test and the Dunn’s post hoc multiple comparison test. Each bar shows the mean ± SD; * , compared to the normal control group; # , compared to the RI group. ** p
