Abstract

Background: Long noncoding RNAs (lncRNAs) are reported that play an important role in regulating tumorigenesis. This study aims to develop a ferroptosis-related lncRNA gene signature for predicting biochemical recurrence of prostate cancer (PCa) and prove a functional lncRNA BCRP3 as a promotor toward PCa progression.

Methods: The ferroptosis-related lncRNA were identified by interoperating the databases of The Cancer Genome Atlas (TCGA) and FerrDb. A predictive model for biochemical recurrence of PCa was established based on the LASSO Cox regression. Kaplan–Meier cures were applied in the measurement of the impact on patients’ survival caused by key lncRNAs. Meanwhile, the molecular assays of CCK8, EdU, wound healing, and Transwell were conducted to evaluate the tumor-suppressive effect of BCRP3 in vitro.

Results: This study presented that 17 differentially expressed ferroptosis-related lncRNAs were confirmed and further screened out 9 key lncRNAs for the establishment of risk model. The nomogram involved the risk model was also proved with an excellent predictive performance toward 1-, 3-, and 5-year survival with the area of curves (AUC) as 0.77, 0.79, and 0.65 separately. Notably, the lncRNA BCRP3 was significantly correlated with the survival of PCa patients based on multivariate Cox regression. Additionally, downregulation of BCRP3 effectively inhibited the proliferation, migration, and invasion of PC3 cells which further proved its anti-tumor function.

Conclusion: We developed a ferroptosis-related lncRNA risk model for predicting biochemical recurrence, which assisting in the clinical therapy of patients with PCa.

与铁突变相关的 LncRNA BCRP3 促进前列腺癌的增殖和迁移
背景:据报道,长非编码RNA(lncRNA)在调控肿瘤发生中发挥着重要作用。本研究的目的是建立一个与铁突变相关的 lncRNA 基因特征,用于预测前列腺癌(PCa)的生化复发,并证明功能性 lncRNA BCRP3 是 PCa 进展的促进因子。 研究方法通过癌症基因组图谱(The Cancer Genome Atlas,TCGA)和FerrDb数据库的互操作,确定了与铁突变相关的lncRNA。基于LASSO Cox回归建立了PCa生化复发的预测模型。在测量关键lncRNA对患者生存的影响时,采用了Kaplan-Meier法。同时,进行了CCK8、EdU、伤口愈合和Transwell等分子检测,以评估BCRP3在体外的抑瘤作用。 结果显示该研究证实了 17 个差异表达的铁蛋白沉积相关 lncRNA,并进一步筛选出 9 个关键 lncRNA 用于建立风险模型。该风险模型所涉及的提名图也被证实对1年、3年和5年生存率具有极佳的预测性能,其曲线面积(AUC)分别为0.77、0.79和0.65。值得注意的是,基于多变量 Cox 回归,lncRNA BCRP3 与 PCa 患者的生存率显著相关。此外,下调 BCRP3 能有效抑制 PC3 细胞的增殖、迁移和侵袭,这进一步证明了它的抗肿瘤功能。 结论我们建立了一个预测生化复发的铁突变相关lncRNA风险模型,有助于PCa患者的临床治疗。

期刊介绍: The European Journal of Cancer Care aims to encourage comprehensive, multiprofessional cancer care across Europe and internationally. It publishes original research reports, literature reviews, guest editorials, letters to the Editor and special features on current issues affecting the care of cancer patients. The Editor welcomes contributions which result from team working or collaboration between different health and social care providers, service users, patient groups and the voluntary sector in the areas of: - Primary, secondary and tertiary care for cancer patients - Multidisciplinary and service-user involvement in cancer care - Rehabilitation, supportive, palliative and end of life care for cancer patients - Policy, service development and healthcare evaluation in cancer care - Psychosocial interventions for patients and family members - International perspectives on cancer care
