摘要

癌症相关成纤维细胞（CAFs）和神经作为肿瘤微环境的组成部分，已分别被证明可直接促进胃肠道癌症的发生。然而，这些细胞是否相互影响以调控癌症进展仍是未知数。我们发现，在结直肠癌（CRC）中，去甲肾上腺素诱导 CAFs 分泌依赖 ADRB2 的神经生长因子（NGF），这反过来又增加了肿瘤内交感神经的支配和去甲肾上腺素的积累。肾上腺素能刺激通过 ADRA2A/Gi- 介导的是相关蛋白（YAP）激活加速了 CRC 的生长。来自 CAFs 的 NGF 可通过 PI3K/AKT 通路直接促进 CRC 细胞生长。用肌球蛋白受体激酶（Trk）抑制剂治疗小鼠，可减少YAP和AKT的活化以及CRC的进展。在人类 CRC 中，NGF 的高表达与间质样肿瘤亚型和患者生存率低有关。这些发现表明，CAF-神经串联在促进 CRC 进展方面发挥着核心作用。用Trk抑制剂阻断这种前馈循环可能是治疗CRC的一种潜在方法。

Neuro-Mesenchymal Interaction Mediated by a β2-Adrenergic Nerve Growth Factor Feedforward Loop Promotes Colorectal Cancer Progression.

Significance: Our work demonstrates that the bidirectional interplay between sympathetic nerves and NGF-expressing CAFs drives colorectal tumorigenesis. This study also offers novel mechanistic insights into catecholamine action in colorectal cancer. Inhibiting the neuro-mesenchymal interaction by TRK blockade could be a potential strategy for treating colorectal cancer.
