Figure Lengend Snippet: Clinical characteristics and prognostic factor PEA15 in the OS autophagy-related model (A) Kaplan-Meier survival analysis of the OS prognostic factor PEA15. (B) Risk survival status plot. (C and D) Univariate and multivariate COX regression analyses of the OS autophagy-related model and various clinical features. (E) mRNA expression levels of PEA15 in the normal osteoblast cell line hFOB1.19 and four osteosarcoma cell lines. (F and G) Validation of knockdown efficiency in U2OS cells and overexpression efficiency in MG63 cells ( n = 3). (H and I) CCK-8 assays of cell proliferation following PEA15 knockdown and overexpression ( n = 3). (J–M) Validation of autophagy activity in human tumor tissues and corresponding statistical analysis ( n = 3). (N and O) Protein expression levels of PEA15 are validated by knockdown and overexpression experiments. The data are presented as mean ± SD. ∗∗ p < 0.01, ∗∗∗ p < 0.001. n.s.: not significant.
