Abstract

OBJECTIVES

To evaluate BCL-2 family signaling molecules in head and neck squamous cell carcinoma (HNSCC) and examine the ability of therapeutic agents with variable mechanisms of action to induce apoptosis in HNSCC cells.

METHODS

messenger ribonculeic acid (mRNA) expression of BAK, BAX, B-cell lymphoma (Bcl-2), BCL2 Like 1 (BCL2L1), and MCL1 were measured in The Cancer Genome Atlas (TCGA) head and neck cancer dataset, as well as in a dataset from a cohort at Montefiore Medical Center (MMC). Protein expression was similarly evaluated in a panel of HNSCC cell lines (HN30, HN31, HN5, MDA686LN, UMSCC47). Cell viability and Annexin V assays were used to assess the efficacy and apoptotic potential of a variety of agents (ABT-263 [navitoclax], A-1210477, and bortezomib.

RESULTS

Expression of BAK, BAX, BCL2L1, and MCL1 were each significantly higher than expression of BCL2 in the TCGA and MMC datasets. Protein expression demonstrated the same pattern of expression when examined in HNSCC cell lines. Treatment with combined ABT-263 (navitoclax)/A-1210477 or with bortezomib demonstrated apoptosis responses that approached or exceeded treatment with staurospaurine control.

CONCLUSION

HNSCC cells rely on inhibition of apoptosis via BCL-xL and MCL-1 overexpression, and induction of apoptosis remains a potential therapeutic option as long as strategies overcome redundant anti-apoptotic signals.

摘要

目的

评估头颈部鳞状细胞癌(HNSCC)中 BCL-2 家族信号分子,并研究作用机制不同的治疗药物诱导 HNSCC 细胞凋亡的能力。

方法

在癌症基因组图谱(TCGA)头颈部癌症数据集以及 Montefiore 医疗中心(MMC)队列的数据集中,测量 BAK、BAX、B 细胞淋巴瘤(Bcl-2)、BCL2 样 1(BCL2L1)和 MCL1 的信使核糖核酸(mRNA)表达。在一系列 HNSCC 细胞系(HN30、HN31、HN5、MDA686LN、UMSCC47)中同样评估蛋白表达。细胞活力和 Annexin V 检测用于评估各种药物(ABT-263[navitoclax]、A-1210477 和硼替佐米)的疗效和凋亡潜力。

结果

TCGA 和 MMC 数据集均显示,BAK、BAX、BCL2L1 和 MCL1 的表达均显著高于 BCL2 的表达。在 HNSCC 细胞系中检测到蛋白表达呈现相同的表达模式。联合使用 ABT-263(navitoclax)/A-1210477 或硼替佐米治疗可诱导接近或超过星形孢菌素对照的凋亡反应。

结论

HNSCC 细胞依赖于 BCL-xL 和 MCL-1 的过度表达抑制凋亡,只要诱导凋亡的策略能够克服冗余的抗凋亡信号,诱导凋亡仍然是一种潜在的治疗选择。
