基底细胞样乳腺癌(BLBC)由于治疗方案少且缺乏有效的靶向治疗药物,临床预后较差。在这里,我们证明了苹果酸酶1(ME1)在BLBC中由于ME1拷贝数扩增而显著上调。ME1的表达增加了葡萄糖的摄取和乳酸的产生,减少了氧气消耗,导致了有氧糖酵解。ME1的表达促进了肿瘤的发生,而抑制ME1的表达则抑制了肿瘤的发生。在乳腺癌患者中,ME1的表达与肿瘤体积大、分级高、生存率差、化疗耐药呈正相关。我们的研究不仅有助于对代谢重编程如何促进BLBC进展的新理解,而且还为这种具有挑战性的疾病提供了一个潜在的预后标志物和治疗靶点。
Basal-like breast cancer (BLBC) is associated with a poor clinical outcome due to the few treatment options and absence of effective targeted agents. Here, we show that malic enzyme 1 (ME1) is dramatically upregulated in BLBC due to ME1 copy number amplification. ME1 expression increases glucose uptake and lactate production, and reduces oxygen consumption, leading to aerobic glycolysis. ME1 expression promotes, whereas knockdown of ME1 expression suppresses tumorigenicity. In breast cancer patients, ME1 expression is positively correlated with large tumor size, high grade, poor survival, and chemotherapy resistance. Our study not only contributes to a new understanding of how metabolic reprogramming contributes to BLBC progression, but also provides a potential prognostic marker and therapeutic target for this challenging disease.
