For instance, in BC, Shen et al. established a prognostic model based on the following genes: HIBCH, OSBPL10, FIG4, OCRL, CPT1A, INPP5F, PTGES3, HSP90AA 1, and ALOX15 with the weight coefficient at 0.2317, 0.2823, 0.1183, 0.2407, 0.1499, 0.0423, 0.2273, 0.0177, and 0.1636, respectively. The gene discussed is ALOX15; the disease is breast cancer.
