E. Growing and differentiated podocytes were treated with SA (300 µM, 30 min) and stained for TRAPPC2 or Sec24C and eIF3. Scale bar, 10 µm. The graphs show quantification of TRAPPC2 and Sec24C (mean intensity) in SGs. Mean ± s.e.m. of three independents experiments. ****p<0.0001, Student's unpaired two-tailed t-test.
