A Immunofluorescence indicating RACK1 (green), G3BP1 (white), and inducible MS2-tagged TM4SF1-AS1 (red) in SNU638 cells. The cells were transfected with a MS2 coat protein (MCP)-RFP plasmid and incubated for 8 days with or without Dox. Magnified views of the respective markers are shown on the right. Scale bars = 10 μm. B Immunofluorescence images of G3PB2 in HSC-45 cells incubated for 8 days with or without Dox and expressing the indicated inducible shRNAs. Representative images are shown on the left. Summarized results are on the right. (n = 5). C, D Apoptosis (C) and cell cycle (D) assays in HSC-45 cells incubated with or without Dox for 8 days and expressing the indicated inducible shRNAs. Representative results are shown on the left. Summarized results are shown on the right. (n = 3). E, F Western blot analysis of PARP, caspase-3 (E) and p38 (F) in HSC-45 cells incubated with or without Dox for 8 days and expressing the indicated inducible shRNAs. Cleaved PARP and cleaved caspase-3 are indicated by arrows (E). Phosphorylated p38 is indicated by an arrow (F). **P < 0.01, ***P < 0.001.
