The ARID family is a superfamily of 15 members containing a domain that interacts with AT-rich DNA elements. However, the expression and prognostic roles of each ARID in breast cancer are still elusive. We used the TCGA and Kaplan-Meier plotter databases to assess the expression and prognostic values of ARID mRNA levels in breast cancer respectively. In the present study, 6 members were significantly lower in tumor tissues than those in the normal tissues, while 6 members were significantly higher. Further assessment of ARID expression in breast cancer with different molecular subtypes, 3 members were significantly higher in no-luminal molecular subtype than those in the luminal molecular subtype, and 6 members were significantly higher. In regard to prognostic values, high expression of ARID1A, ARID2, ARID3B, ARID4A, ARID5A, ARID5B, JARID1A were associated with favorable outcome, while ARID4B and JARID1B were correlated to a worse outcome. We further analyzed the prognostic value of ARID in different intrinsic subtypes and clinicopathological features of breast cancer. We found many meaningful ARID family biomarkers in breast cancer. The relevant results will expound the role of ARID in breast cancer and may further provide new insight to explore the ARID-targeting reagents for treating breast cancer patients.
ARID 家族是一个包含与富含 AT 的 DNA 元件相互作用的结构域的 15 个成员的超家族。然而,每个 ARID 在乳腺癌中的表达和预后作用仍不清楚。我们分别使用 TCGA 和 Kaplan-Meier plotter 数据库评估 ARID mRNA 水平在乳腺癌中的表达和预后价值。在本研究中,有 6 个成员在肿瘤组织中的表达明显低于正常组织,而有 6 个成员的表达明显升高。进一步评估 ARID 在不同分子亚型乳腺癌中的表达,有 3 个成员在非腔面分子亚型中的表达明显高于腔面分子亚型,而有 6 个成员的表达明显升高。至于预后价值,ARID1A、ARID2、ARID3B、ARID4A、ARID5A、ARID5B 的高表达与良好的预后相关,而 ARID4B 和 JARID1B 与较差的预后相关。我们进一步分析了 ARID 在乳腺癌不同内在亚型和临床病理特征中的预后价值。我们在乳腺癌中发现了许多有意义的 ARID 家族生物标志物。相关结果将阐述 ARID 在乳腺癌中的作用,并可能进一步为探索针对 ARID 的靶向试剂治疗乳腺癌患者提供新的见解。
