As shown in Table 2, the low mRNA expression of ARID1B (p=0.0023), ARID2 (p=0.0439), ARID4A (p=0.0056), ARID4B (p=0.0317), ARID5B (p=0.00054), JARID1D (p=0.043), JARID2 (p=0.0068) were interrelated with poor survival in breast cancer patients with negative lymph node. The gene discussed is ARID2; the disease is breast carcinoma.
