Article Title: A tumor cell specific Zona Pellucida glycoprotein 3 RNA transcript encodes an intracellular cancer antigen

doi: 10.3389/fonc.2023.1233039

Figure Lengend Snippet: ZP3-Cancer is the dominant transcript in tumor cells and is differentially distributed among cancer types. (A) Expression of the seven annotated ZP3 transcripts in CCls (n=1339). Bars represent Tukey box plots (boxes are median+IQR). Median transcript expression levels (from left to right) are 2.47, 0.22, 0.0, 0.04, 0.42, 0.0 and 0.0 TPM. ZP3-Cancer expression is significantly higher compared to all other transcripts (Kruskal-Wallis test, p < 0.0001). NC = Non-protein coding. (B) Relative expression of ZP3-cancer and ZP3-Oocyte in the CCLs MCF7 and HeLa, and in healthy ovarian tissue containing follicles, as determined by qPCR. ZP3-Cancer expression is set to 1 for MCF7 and HeLa, ZP3-Oocyte expression is set to 1 for ovarian tissue. ‘ZP3-both’ served as a positive control and used primers designed to detect ZP3-Cancer and ZP3-Oocyte simultaneously. Bars represent mean+SD for the triplicate qPCR reactions. (C) Differential expression of ZP3-Cancer in the cancer types covered by the CCLs. Cancer types represented by less than 5 CCLs were not included. Bars represent Tukey box plots (boxes are median+IQR). Number of samples are indicated between brackets. The shaded area indicates CCLs with a ZP3-Cancer expression level below the overall median (2.54 TPM).

(A) TGFA diagnostic ROC curve; the area under the ROC curve is between 0.5 and 1. The closer the AUC is to 1, the better the diagnostic effect. When the AUC is between 0.5 and 0.7, the accuracy is low, when the AUC is between 0.7 and 0.9, the accuracy is moderate, and when the AUC is above 0.9, the accuracy is high. (B, C) Clinical significance of TGFA expression with age and menopausal status. (D–F) Stratified KM survival curves for overall survival (OS), disease‐specific survival (DSS), and progression‐free period (PFI) based on TGFA expression.
