The mechanism of metabolic crosstalk between different tissues in the host remains poorly understood but is likely to play important roles in tumor growth and cachexia. A recent study from Naser, Jackstadt, et al. utilizes isotope tracing in a zebrafish melanoma model and finds that tumors secrete alanine into circulation, which is taken up by the liver and used for gluconeogenesis.
宿主不同组织之间的代谢串扰机制仍不清楚,但可能在肿瘤生长和恶病质中发挥重要作用。Naser、Jackstadt 等人最近的一项研究利用同位素示踪在斑马鱼黑色素瘤模型中发现,肿瘤将丙氨酸分泌到循环中,然后被肝脏摄取用于糖异生。
