Apoptosis was associated with patient prognosis in HER2-enriched and luminal-A breast cancers through enriched GO processes such as ‘negative regulation of apoptotic process’ (QHER2 = 0.030, 122 genes; QluminalA = 0.015, 228 genes) and ‘programmed cell death’ (QHER2 = 0.015, 125 genes; QluminalA = 0.016, 231 genes) (Fig. 3c). The gene discussed is ERBB2; the disease is breast cancer.
