概括
尤贡因J是一种天然化合物,通过向上皮层-介质细胞转换 (EMT) 和ADAM9.9来有效抑制前列腺癌 (PCa) 转移. 这一发现为先进的PCa治疗提供了一个有前途的新疗法途径.
科学领域:
- 在瘤学瘤学.
- 自然产品化学 自然产品化学
- 分子生物学分子生物学
背景情况:
- 前列腺癌 (PCa) 是一种普遍存在的恶性瘤,通常与晚期的远程转移有关.
- 研究天然化合物的抗转移性质对于开发新型癌症疗法至关重要.
研究的目的:
- 为了评估Ugonin J的抗转移作用,一种来自*Helminthostachys zeylanica*的化合物,对前列腺癌.
- 阐明Ugonin J对PCa细胞运动的作用背后的分子机制.
主要方法:
- 细胞迁移和入侵试验被用来评估Ugonin J对PCa细胞运动性的影响.
- 逆转录定量PCR (RT-qPCR),西部抹杀和RNA测序 (RNA-seq) 用于分析基因和蛋白质表达变化.
- 使用多个数据库进行临床数据分析,以将基因表达与PCa患者的结果相关联.
主要成果:
- 乌贡因J显著抑制PCa细胞迁移和入侵,而不会影响细胞活力.
- RNA-seq数据表明,Ugonin J通过降低介质细胞标记物 (N-cadherin,β-catenin,Snail,Slug) 的调节和上调E-cadherin) 来抑制表皮细胞-介质细胞过渡 (EMT).
- 乌贡因J降低了ADAM9的表达,这种蛋白质在PCa患者中被发现是上调的,并且与转移有关. 过度表达ADAM9逆转了Ugonin J的抗运动作用,突出了ADAM9在PCa转移中的作用.
- 乌贡因J通过PI3K/Akt和NF-κB通路抑制ADAM9依赖的运动性.
结论:
- 乌贡因J在前列腺癌模型中表现出显著的抗转移活性.
- 该化合物通过抑制EMT和降低ADAM9的调节作用,ADAM9是PCa转移的关键媒介.
- 乌戈宁J代表了转移性前列腺癌治疗的有希望的治疗候选者.

Cancer Cell Migration through Invadopodia
3.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Metastasis
6.7K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
