Purpose Yes associated protein 1 (YAP1), which is a standout amongst the most essential effectors of the Hippo pathway, assumes a vital part in a few kinds of cancer. However, whether YAP1 is an oncogene in CRC (colorectal cancer) remains controversial, and the association between the subcellular localization of YAP1 and clinical implications in CRC remains unknown. Patients and methods In this study, we investigated the subcellular localization of YAP1 in CRC cells by immunohistochemistry and then associate these findings with clinical information in a large CRC cohort with 919 CRC patients. Results The results show that CRC tissues has a significant higher expression of cytoplasmic YAP1 compared to adjacent normal tissues (all P < 0.001). Cytoplasmic YAP1 expression was significantly associated with the number of lymph nodes removed and differentiation grade (all P < 0.001). Furthermore, after correcting confounding variables, for example, TNM stage and differentiation grade, the multivariate Cox analysis confirmed cytoplasmic YAP1-high subgroup had a significant shorter DFS (HR = 3.255; 95% CI [2.290–4.627]; P < 0.001) and DSS (HR = 4.049; 95% CI [2.400–6.830]; P < 0.001) than cytoplasmic YAP1-low subgroup. High cytoplasmic YAP1 expression is associated with a worse survival in stage III CRC patients who received chemotherapy. Conclusion Cytoplasmic YAP1 could be could be utilized as a prognosis factor in CRC patients, and may be an indicator of whether certain patients population could benefit from postoperative chemotherapy.

细胞质 YAP1 高表达预示结直肠癌患者预后不良

目的 Yes 相关蛋白 1 (YAP1) 是 Hippo 通路最重要的效应子中的佼佼者,在几种癌症中发挥着重要作用。然而,YAP1 是否是 CRC(结直肠癌)中的致癌基因仍然存在争议,并且 YAP1 的亚细胞定位与 CRC 临床意义之间的关联仍然未知。患者和方法 在这项研究中,我们通过免疫组织化学研究了 YAP1 在 CRC 细胞中的亚细胞定位,然后将这些发现与包含 919 名 CRC 患者的大型 CRC 队列中的临床信息相关联。结果结果显示结直肠癌组织的胞质YAP1表达明显高于癌旁正常组织(均P<0.001)。细胞质 YAP1 表达与切除的淋巴结数量和分化程度显着相关(均 P < 0.001)。此外,在校正混杂变量后,例如 TNM 分期和分化等级,多变量 Cox 分析证实细胞质 YAP1 高亚组的 DFS 显着缩短(HR = 3.255;95% CI [2.290–4.627];P < 0.001)和DSS (HR = 4.049; 95% CI [2.400–6.830]; P < 0.001) 低于细胞质 YAP1-low 亚组。在接受化疗的 III 期 CRC 患者中,高细胞质 YAP1 表达与较差的生存率相关。结论 细胞质 YAP1 可作为 CRC 患者的预后因素,并可能是某些患者群体是否可以从术后化疗中获益的指标。此外,在校正混杂变量后,例如 TNM 分期和分化等级,多变量 Cox 分析证实细胞质 YAP1 高亚组的 DFS 显着缩短(HR = 3.255;95% CI [2.290–4.627];P < 0.001)和DSS (HR = 4.049; 95% CI [2.400–6.830]; P < 0.001) 低于细胞质 YAP1-low 亚组。在接受化疗的 III 期 CRC 患者中,高细胞质 YAP1 表达与较差的生存率相关。结论 细胞质 YAP1 可作为 CRC 患者的预后因素,并可能是某些患者群体是否可以从术后化疗中获益的指标。此外,在校正混杂变量后,例如 TNM 分期和分化等级,多变量 Cox 分析证实细胞质 YAP1 高亚组的 DFS 显着缩短(HR = 3.255;95% CI [2.290–4.627];P < 0.001)和DSS (HR = 4.049; 95% CI [2.400–6.830]; P < 0.001) 低于细胞质 YAP1-low 亚组。在接受化疗的 III 期 CRC 患者中,高细胞质 YAP1 表达与较差的生存率相关。结论 细胞质 YAP1 可作为 CRC 患者的预后因素,并可能是某些患者群体是否可以从术后化疗中获益的指标。多变量 Cox 分析证实,细胞质 YAP1 高亚组的 DFS 显着缩短(HR = 3.255;95% CI [2.290–4.627];P < 0.001)和 DSS(HR = 4.049;95% CI [2.400–6.830];P < 0.001) 比细胞质 YAP1-low 亚组。在接受化疗的 III 期 CRC 患者中,高细胞质 YAP1 表达与较差的生存率相关。结论 细胞质 YAP1 可作为 CRC 患者的预后因素,并可能是某些患者群体是否可以从术后化疗中获益的指标。多变量 Cox 分析证实,细胞质 YAP1 高亚组的 DFS 显着缩短(HR = 3.255;95% CI [2.290–4.627];P < 0.001)和 DSS(HR = 4.049;95% CI [2.400–6.830];P < 0.001) 比细胞质 YAP1-low 亚组。在接受化疗的 III 期 CRC 患者中,高细胞质 YAP1 表达与较差的生存率相关。结论 细胞质 YAP1 可作为 CRC 患者的预后因素,并可能是某些患者群体是否可以从术后化疗中获益的指标。
