A polyamine metabolism risk signature for predicting the prognosis and immune therapeutic response of kidney cancer

Bo Li,
Zheng Kong,
Yang Liu
et al.

Abstract: Background Polyamine metabolism is critically involved in the proliferation and metastasis of tumor cells, including in kidney renal clear cell (KIRC) cancer. However, the molecular mechanisms underlying the effect of polyamines in KIRC cancer remain largely unknown. Methods The messenger RNA (mRNA) expression profile of KIRC was downloaded from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), and ArrayExpress database. Differential expression analysis was… Show more

“…The same analyses were performed in another two external validation cohorts, and the results proved to be the same trends (Figure 6B, 6C; Supplementary Figure 6B, 6C). We then compared our PRERG signature with nine other risk signatures [24][25][26][27][28][29][30][31][32]. PRERGs risk signature showed the top 3 of AUC for 3-/5-/7-year prognosis of the KIRC patients (Supplementary Figure 7A-7C), indicating that our risk signature has a higher predicted accuracy.…”
