长非编码RNA在辅助性T细胞发育中起着关键作用,但对其在Treg分化中的作用以及在肝细胞癌进展过程中的功能知之甚少。在此,我们发现,在患者和异种移植小鼠模型中,Tregs中lnc-表皮生长因子受体(EGFR)的上调与肿瘤大小和EGFR/Foxp3的表达呈正相关,而与干扰素-γ的表达呈负相关。LNC-EGFR以EGFR依赖的方式刺激Treg分化,抑制CTL活性,促进肝癌生长。在机制上,lnc-EGFR与EGFR特异性结合,阻断其与c-cbl的相互作用和泛素化,稳定c-cbl并增强其自身及其下游AP-1/NF-AT1轴的活化,进而诱导EGFR的表达。LNC-EGFR通过促进Treg细胞分化将免疫抑制状态与癌症联系起来,从而为肝癌提供了一个潜在的治疗靶点。长的非编码RNA在调节肿瘤微环境中的T细胞分化中的作用尚不清楚。在这里,作者发现了一种lncRNA,通过与EGFR的直接相互作用,促进肝细胞癌微环境中的T调节细胞分化,从而通过免疫抑制促进肿瘤生长。
Long noncoding RNAs play a pivotal role in T-helper cell development but little is known about their roles in Treg differentiation and functions during the progression of hepatocellular carcinoma (HCC). Here, we show that lnc-epidermal growth factor receptor (EGFR) upregulation in Tregs correlates positively with the tumour size and expression of EGFR/Foxp3, but negatively with IFN-γ expression in patients and xenografted mouse models. Lnc-EGFR stimulates Treg differentiation, suppresses CTL activity and promotes HCC growth in an EGFR-dependent manner. Mechanistically, lnc-EGFR specifically binds to EGFR and blocks its interaction with and ubiquitination by c-CBL, stabilizing it and augmenting activation of itself and its downstream AP-1/NF-AT1 axis, which in turn elicits EGFR expression. Lnc-EGFR links an immunosuppressive state to cancer by promoting Treg cell differentiation, thus offering a potential therapeutic target for HCC. The role of long noncoding RNAs in regulating T-cell differentiation within the tumour microenvironment is unclear. Here the authors identify a lncRNA that, through direct interactions with EGFR, promotes T-regulatory cell differentiation within the microenvironment of hepatocellular carcinoma, thus promoting tumour growth via immune suppression.
