骨转移发生在晚期前列腺癌(PCa)患者中。PCa和骨微环境之间的细胞-细胞相互作用形成恶性循环,其调节骨微环境,增加骨畸形,并驱动骨中的肿瘤生长。然而,PCa介导的骨微环境调节的分子机制是复杂的,并且仍然不清楚。在这里,我们评估了生长分化因子-15(GDF 15)的功能,在体内临床前前列腺癌骨转移小鼠模型和体外骨细胞共培养系统。我们的研究结果表明,前列腺素C分泌的GDF 15促进骨转移,并诱导骨微结构的改变,在临床前异种移植模型。机制研究表明,GDF 15通过成骨细胞产生CCL 2和RANKL以及募集骨瘤细胞激活破骨细胞生成,从而增加成骨细胞功能并促进骨中PCa的生长。总之,我们的研究结果证明了GDF 15在调节骨微环境和随后的PCa骨转移发展中的关键作用。
Bone metastases occur in patients with advanced-stage prostate cancer (PCa). The cell-cell interaction between PCa and the bone microenvironment forms a vicious cycle that modulates the bone microenvironment, increases bone deformities, and drives tumor growth in the bone. However, the molecular mechanisms of PCa-mediated modulation of the bone microenvironment are complex and remain poorly defined. Here, we evaluated growth differentiation factor-15 (GDF15) function using in vivo preclinical PCa-bone metastasis mouse models and an in vitro bone cell coculture system. Our results suggest that PCa-secreted GDF15 promotes bone metastases and induces bone microarchitectural alterations in a preclinical xenograft model. Mechanistic studies revealed that GDF15 increases osteoblast function and facilitates the growth of PCa in bone by activating osteoclastogenesis through osteoblastic production of CCL2 and RANKL and recruitment of osteomacs. Altogether, our findings demonstrate the critical role of GDF15 in the modulation of the bone microenvironment and subsequent development of PCa bone metastasis.
