Importantly, when the other survival endpoints-DSS (disease-specific survival), DFI (disease-free interval), and PFI (progression-free interval)-were analyzed, ITIH1 appeared to be the only gene that was constantly substantial for all endpoints in LIHC (Figure 4B). Furthermore, we confirmed the outstanding downregulation of ITIH1 in LIHC in 5 GEO datasets (GSE1898, GSE39791, GSE45436, GSE6764, and GSE84598) (Figure 5A). Applying these five datasets, we also analyzed the correlation in between the expression of ITIH1 and alpha-fetoprotein (AFP) (probably the most frequently used diagnostic marker for LIHC). We located that ITIH1 correlated negatively with AFP in 3 of 5 datasets, with strongest correlation in the GSE1898 dataset (Figure 5B). Then, the diagnostic performances from the two genes had been assessed by analyses of ROC curves. As shown in Figure 5C, the location below the ROC curve (AUC) of ITIH1 was consistently higher than that of AFP in all five datasets analyzed. This suggests that, at the mRNA level, the diagnostic value of ITIH1 may very well be at least as great as that of AFP, though the utility awaits future experimental validation. Furthermore, the superior prognostic impact of ITIH1 was validated in two independent cohorts of LIHC patients (GSE1898, n = 76; GSE14520, n = 221) (Figure 5D).Consequently, subsequent analyses will focus on the ITIH1 gene, specifically on its roles in LIHC. The genetic and epigenetic features of ITIH1 in pancancers Subsequent, we explored the genetic alterations of ITIH1 in TCGA pan-cancer datasets employing the cbioportal for Cancer Genomics (http://www.cbioportal.org). We observed that the overall mutation rate of ITIH1 in cancers is comparatively low (less than 10 ). Melanoma demonstrated the highest frequency of ITIH1 mutation (8.33 ), followed by uterine cancer (five.86 ) (Figure 6A). cBioPortal Oncoprint showed that missense mutation was the main mutation kind of ITIH1 and most mutations have been CT (Supplementary Figure ten). No hot spot mutation web site was detected for ITIH1 in pan-cancers (Figure 6B). For copy quantity variations (CNVs) of ITIH1, amplification was most regularly observed in esophagus cancer (1.65 ), although deletion occasion occurred a lot more normally in diffusive big B-cell lymphoma (DLBC) (4.17 ) (Figure 6A). In LIHC, despite significantly dysregulated expression of ITIH1, the total genetic alteration rate appeared to be really low (1.34 ) (Figure 6A). Moreover, we analyzed the correlation among ITIH1 expression and TMB (Tumor mutational burden)/MSI (Microsatellite instability) across 33 cancer sorts. We located that ITIH1 was negatively correlated with TMBFigure three.

A damaging correlation involving ITIH1 expression and MSI was noticed in PAAD, Pheochromocytoma and Paraganglioma (PCPG), and STAD, whereas a constructive correlation was identified for Prosta.
