BackgroundThe adhesion G-蛋白偶联受体(GPCRs)在肿瘤发病机制中起着至关重要的作用,然而,它们在胰腺导管腺癌(PDAC)中的临床意义尚不清楚。MethodsWe分析了796例PDAC患者,包括331例来自公共数据集(TCGA,ICGC和GSE 57495)和465例来自独立队列(训练:n= 321,验证:n= 144)。使用体外研究,我们证实了候选GPCRs.ResultsAnalysis的生物学功能的所有33个粘附GPCRs,导致识别GPR 115,作为唯一的显着的预后因素,在所有的公共数据集。GPR 115高表达组患者的OS和RFS预后在训练队列(P<0.01,P < 0.01)和验证队列(P<0.01,P = 0.04)中均显著较差。多因素分析显示GPR 115高表达是两组患者的独立预后因素(HR = 1.43;P= 0.01,HR = 2.55;P< 0.01)。通过结合GPR 115和临床病理学因素,使用考克斯回归的风险预测模型准确预测了手术后5年生存率。此外,GPR 115沉默抑制细胞增殖和迁移在PDAC cells.ConclusionWe证明,GPR 115具有重要的预后意义和功能作用,在肿瘤的进展,提供了一个理由,这可能是一个潜在的治疗目标,在PDAC患者。
BackgroundThe adhesion G-protein-coupled receptors (GPCRs) play crucial roles in tumour pathogenesis, however, their clinical significance in pancreatic ductal adenocarcinoma (PDAC) remains unclear.MethodsWe analysed 796 PDAC patients, including 331 from public data sets (TCGA, ICGC and GSE57495) and 465 from independent cohorts (training:n= 321, validation:n= 144). Using in-vitro studies, we confirmed the biological function of the candidate GPCRs.ResultsAnalysis of all 33 adhesion GPCRs, led to identify GPR115, as the only significant prognostic factor in all public data sets. The patients with high GPR115 expression exhibited significantly poorer prognosis for OS and RFS, in training (P< 0.01,P< 0.01) and validation cohort (P< 0.01,P= 0.04). Multivariate analysis indicated that GPR115 high expression was an independent prognostic factor in both cohorts (HR = 1.43;P= 0.01, HR = 2.55;P< 0.01). A risk-prediction model using Cox regression by incorporating GPR115 and clinicopathological factors accurately predicted 5-year survival following surgery. In addition, GPR115 silencing inhibited cell proliferation and migration in PDAC cells.ConclusionWe demonstrated that GPR115 has important prognostic significance and functional role in tumour progression; providing a rationale that this may be a potential therapeutic target in patients with PDAC.
