Effects of resveratrol on NIS protein expression in rat thyroid glands.

<p>Male Sprague-Dawley rats were treated with the control vehicle (Control, n = 4) or with 50 mg/kg/day resveratrol i.p. (Resv, n = 4), for 14 days. On day 15^th, the animals were sacrificed and their thyroids were removed. Immunofluorescence analysis was performed using a mouse monoclonal anti-NIS antibody and an anti-mouse fluorescein-conjugated secondary antibody, Alexa Fluor 488, (green). Po-Pro-3 iodide was used to stain the nuclei (red). The negative control was performed using a mouse IgG preparations instead of the primary antibody (data not shown). The slides were visualized under a Zeiss LSM S10 confocal microscope with a x40 immersion lens. Representative data from four experiments are showed.
