FIGURE 1 | Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) ORF3a triggers incomplete autophagy. (A–B) SARS-CoV-2 infection triggers incomplete autophagy. HeLa-hACE2 (A) or Vero-E6 (B) cells were infected with SARS-CoV-2 (MOI = 1) and cell lysates were collected at indicated time point post-infection for immunoblotting (IB) with indicated antibodies. (C) Screening of SARS-CoV-2-encoded proteins for <t>LC3-I</t> to LC3-II conversion in HeLa cells. (D,E) SARS-CoV-2 ORF3a induces incomplete autophagy. HeLa-vector and HeLa-ORF3a stable cells were treated with or without BafA1 (100 nM) for 4 h and the cell lysates were collected for IB with indicated antibodies (D). HeLa cells were transfected with increasing amount ORF3a expressing plasmid and the cell lysates were collected for IB with indicated antibodies at 48 post-transfection (E). (F) ORF3a expression modulates autophagy in Vero-E6 cells. (G) ORF3a blocks SQSTM1/p62 degradation upon starvation. HeLa-vector or HeLa-ORF3a stable cells were treated by serum starvation for 4 h and the cell lysates were collected for IB with indicated antibodies. (H,I) SARS-CoV-2 ORF3a induces LC3 puncta formation. HeLa-vector or HeLa-ORF3a cell line were treated with BafA1 (100 nM) and endogenous LC3 puncta were immunostained (H) and quantified (I). Scale bar, 15 µm. Arrow: representative autophagosomes. (J,K) HeLa-mRFP-GFP-LC3 stable cells were transfected with ORF3a or vector control and transfected cells were fixed and the LC3 puncta were captured (J,K) quantified as indicated. Yellow puncta, autophagosomes; Red puncta, autolysosomes; Arrow, representative autophagosomes. p62/GAPDH or LC3-II/GAPDH levels were quantified by the band intensity in (A–G).

Fig. 3. Pharmacological effects of everolimus in normal kidney epithelial cell lines.(A) Human kidney 2 (HK-2), Madin–Darby canine kidney (MDCK), and normal rat kidney epithelial (NRK-52E) cells were treated with everolimus (Eþ, 100 nM) or vehicle (E) for 48 h. After treatment, whole-cell extracts were obtained and examined with Western blotting using antibodies against LC3 and glyceraldehyde 3-phosphate dehydrogenase (GAPDH). GAPDH was used as a loading control to determine the relative densities of the bands in each lane. The ratio of the density of everolimus-treated cells to that of vehicle-treated cells was calculated. Each column represents the mean7S.E.M. (n¼3; *Po0.05, significantly different).
