In the research on the connection of HOXD1 with DSS, the results showed that high expression of HOXD1 could lead to short DSS in ACC, MESO, STAD (p < 0.01) (Figure 3J); HOXD3 in ACC, BLCA, KIRP, LGG, LIHC, READ, and STAD (p < 0.01) (Figure 3K); HOXD4 in ACC, GBM, KIRP, LGG, LUAD, MESO, READ, STAD, and THCA (p < 0.01) (Figure 3L). The gene discussed is HOXD1; the disease is glioblastoma.
