Figure Lengend Snippet: Effect of OSGIN1 on the autophagic flux. OSGIN1 was either overexpressed by lentiviral vector or suppressed by siRNA in the primary basal cells and then treated with BafA1, a late stage inhibitor of autophagic flux. The changes of autophagy markers MAP1LC3B and SQSTM1 were assessed by western analysis with ACTB as a loading control. (A) Overexpression of OSGIN1 with BafA1 treatment. Fold-changes between lenti-OSGIN1 and lenti-control from 3 independent experiments are shown. Note the consistent upregulation of SQSTM1 and MAP1LC3B-II by lenti-OSGIN1 with or without BafA1 (all fold-changes >1). (B) Knockdown OSGIN1 with BafA1 treatment. Folds changes between si-OSGIN1 and si-control from 3 independent experiments are shown. Note there are no consistent changes.
Article Snippet: 12,15,17,21 BafA1 (StressMarq, SKC-135) was used (100 nM, 2 h) to block the late-stage autophagic flux.
