探讨乳腺癌L-型氨基酸转运蛋白1(LAT1)基因的表达及小动物正电子断层扫描仪(micro-PET)示踪检测乳腺癌的价值。
检测乳腺癌细胞LAT1 mRNA和蛋白表达水平,以18F-氟环丁烷羧酸(18F-FACBC)为显像剂的micro-PET示踪检测裸鼠种植的乳腺癌。
非致瘤乳腺细胞系MCF-10A表达低水平的LAT1 mRNA和蛋白,而恶性的癌细胞系MCF-7表达高水平的LAT1 mRNA和蛋白;抑制LAT1可抑制乳腺癌细胞增殖;以18F-FACBC为显像剂的micro-PET能有效检测裸鼠种植的乳腺癌。
乳腺癌高表达LAT1,LAT1可作为诊断乳腺癌的生物标志物,18F-FACBC与LAT1可用于micro-PET示踪检测乳腺癌。
