Figure 3. Generation of stable GFP-LC3 expressing HCC cell line.
(A, C) Highly metastatic HCCLM3 cell line stably expressing GFP-LC3 reporter gene (HCCLM3-GFP-LC3) was generated via lentivirus-mediated GFP-LC3 overexpression. The HCCLM3-GFP-LC3 cells exhibited a large number of GFP-LC3 dots after rapamycin treatment (+Rapa). (B, C) HCCLM3 stably expressing GFP (HCCLM3-GFP) served as Control. The HCCLM3-GFP cells displayed no GFP-LC3 dots after rapamycin treatment (+Rapa). (D) Western blot analysis of LC3 showed that rapamycin induced intense autophagy in both HCCLM3-GFP-LC3 and HCCLM3-GFP.
