Effect of SIRT6 inhibition on the level of acetylated α-tubulin in porcine oocytes. (A) Representative images of α-tubulin acetylation in control and SIRT6-inhibited oocytes. Porcine oocytes were immunostained with acetyl-α-tubulin (Lys40) antibody and counterstained with propidium iodide (PI). Scale bar, 10 μm. (B) The fluorescence intensity of acetyl-α-tubulin signals was quantified in control and SIRT6-inhibited oocytes. Data were expressed as the mean percentage (mean ± SEM) of at least three independent experiments. ***P < 0.001. (C) The levels of acetylated α-tubulin in control and SIRT6-inhibited oocytes were detected by immunoblotting. The oocytes were immunoblotted for acetyl-α-tubulin (Lys40) and glyceraldehyde 3-phosphate dehydrogenase (GAPDH), respectively.
