Reprogramming of energy metabolism in the development of prostate cancer can be exploited for a better diagnosis and treatment of the disease. The goal of this study was to determine whether differences in glucose and pyruvate metabolism of human prostate cancer cells with dissimilar aggressivenesses can be detected using hyperpolarized [1‐13C]pyruvate MRS and [18F]FDG‐PET imaging, and to evaluate whether these measures correlate. For this purpose, we compared murine xenografts of human prostate cancer LNCaP cells with those of more aggressive PC3 cells. [1‐13C]pyruvate was hyperpolarized by dissolution dynamic nuclear polarization (dDNP) and [1‐13C]pyruvate to lactate conversion was followed by 13C MRS. Subsequently [18F]FDG uptake was investigated by static and dynamic PET measurements.

人前列腺癌细胞模型中的丙酮酸-乳酸交换和葡萄糖摄取。通过超极化 [1-13 C] 丙酮酸 MRS 和 [ 18 F] FDG-PET 对异种移植物和悬浮液进行的研究。

可以利用前列腺癌发展过程中能量代谢的重编程来更好地诊断和治疗该疾病。本研究的目的是确定是否可以使用超极化 [1- 13 C]丙酮酸 MRS 和 [ 18 F]FDG-PET 成像检测具有不同侵袭性的人前列腺癌细胞的葡萄糖和丙酮酸代谢差异,并评估是否这些措施相互关联。为此,我们将人前列腺癌 LNCaP 细胞的鼠异种移植物与更具攻击性的 PC3 细胞的异种移植物进行了比较。[1- 13 C]丙酮酸通过溶解动态核极化(dDNP)超极化,[1- 13 C]丙酮酸转化为乳酸,随后13C 夫人。随后通过静态和动态PET测量研究[ 18 F]FDG摄取。
