The expression of ARID1A, ARID1B, ARID2, ARID3A, ARID4A, and ARID4B in no-luminal subtypes was lower than luminal subtypes, however, ARID3C, ARID5A, and JARID2 mRNA expression were higher in no-luminal subtypes of breast cancer tissues (Figure 1B–1J). The gene discussed is ARID3C; the disease is breast cancer.
