Additionally, Kaplan–Meier analysis from both the GSE41258 dataset and Cancer Genome Atlas (TCGA) mRNA‐seq dataset revealed that higher NOD1 expression in tumours was associated with decreased overall survival (OS) rates (Figure 6i,j), suggesting a poor prognosis for patients with CRC and high levels of NOD1. The gene discussed is NOD1; the disease is colorectal carcinoma.
