摘要

目的 表皮生长因子受体(EGFR)的过度激活在非小细胞肺癌(NSCLC)中起着至关重要的作用。刺猬(Hh)信号与多种癌症的肿瘤发生和进展有关,但其在非小细胞肺癌细胞中的功能仍存在争议。在此,我们提出了一个新发现,挑战了目前对Hh信号在肿瘤生长中的作用的理解。方法使用TCGA数据集、免疫印迹法和免疫组化法评估Hh配体和受体的表达。使用集落形成、细胞计数试剂盒-8(CCK-8)和异种移植试验检测了Hh配体和受体在NSCLC中的生物学功能。结果Hh配体和受体在NSCLC组织中的表达受到抑制,这些基因的低表达水平与预后不良有关。Ptch1与表皮生长因子受体结合,促进其多泛素化和降解,而不受下游转录信号的影响。此外,Hh 配体与 Ptch1 合作调节表皮生长因子受体的蛋白稳定性和活性。结论 非规范 Hh 信号通路涉及 Hh 配体及其受体 Ptch1 之间的合作,促进了表皮生长因子受体的降解并削弱了其在 NSCLC 中的活性。这些发现为表皮生长因子受体蛋白稳定性和活性的调控提供了新的见解,为 NSCLC 的分子分型提供了新的诊断指标,并为这种具有挑战性的疾病的靶向治疗确定了潜在的目标。

Hedgehog ligand and receptor cooperatively regulate EGFR stability and activity in non-small cell lung cancer

Purpose

The hyperactivation of epidermal growth factor receptor (EGFR) plays a crucial role in non-small cell lung cancer (NSCLC). Hedgehog (Hh) signaling has been implicated in the tumorigenesis and progression of various cancers, however, its function in NSCLC cells remains controversial. Herein, we present a novel finding that challenges the current understanding of Hh signaling in tumor growth.

Methods

Expression of Hh ligands and receptor were assessed using TCGA datasets, immunoblotting and immunohistochemical. Biological function of Hh ligands and receptor in NSCLC were tested using colony formation, cell count kit-8 (CCK-8) and xenograft assays. Biochemical effect of Hh ligands and receptor on regulating EGFR stability and activity were checked via immunoblotting.

Results

Expression of Hh ligands and receptor was suppressed in NSCLC tissues, and the lower expression levels of these genes were associated with poor prognosis. Ptch1 binds to EGFR and facilitates its poly-ubiquitylation and degradation independent of downstream transcriptional signaling. Moreover, Hh ligands cooperate with Ptch1 to regulate the protein stability and activity of EGFR. This unique mechanism leads to a suppressive effect on NSCLC tumor growth.

Conclusion

Non-canonical Hh signaling pathway, involving cooperation between Hh ligands and their receptor Ptch1, facilitates the degradation of EGFR and attenuates its activity in NSCLC. These findings provide novel insights into the regulation of EGFR protein stability and activity, offer new diagnostic indicators for molecular typing of NSCLC and identify potential targets for targeted therapy of this challenging disease.

期刊介绍: The Official Journal of the International Society for Cellular Oncology Focuses on translational research Addresses the conversion of cell biology to clinical applications Cellular Oncology publishes scientific contributions from various biomedical and clinical disciplines involved in basic and translational cancer research on the cell and tissue level, technical and bioinformatics developments in this area, and clinical applications. This includes a variety of fields like genome technology, micro-arrays and other high-throughput techniques, genomic instability, SNP, DNA methylation, signaling pathways, DNA organization, (sub)microscopic imaging, proteomics, bioinformatics, functional effects of genomics, drug design and development, molecular diagnostics and targeted cancer therapies, genotype-phenotype interactions. A major goal is to translate the latest developments in these fields from the research laboratory into routine patient management. To this end Cellular Oncology forms a platform of scientific information exchange between molecular biologists and geneticists, technical developers, pathologists, (medical) oncologists and other clinicians involved in the management of cancer patients. In vitro studies are preferentially supported by validations in tumor tissue with clinicopathological associations.
