Figure Lengend Snippet: Mechanistic insights into PEA15 downstream signaling (A) Heatmap of transcriptomic analysis in U2OS cells following PEA15 knockdown. (B) CCK-8 assay was adopted to assess cell proliferation after FABP3 knockdown in U2OS cells ( n = 3). (C) Colony formation assay in U2OS cells with FABP3 knockdown ( n = 3). (D and E) Migration and invasion assays in U2OS cells with FABP3 knockdown, along with the expression levels of related proteins ( n = 3). (F and G) Fluorescence imaging of autophagic activity and expression of autophagy-related proteins following FABP3 knockdown. (K–L) Flow cytometry analysis of apoptosis and expression of apoptosis-related markers after FABP3 knockdown ( n = 3). (M) KEGG pathway analysis of transcriptomic data from U2OS cells with PEA15 knockdown. (N) In U2OS cells with PEA15 knockdown, FABP3 was overexpressed, followed by the detection of ATG5 and LC3B protein expression levels.
