摘要

由一名新闻记者-机器人与机器学习的工作人员新闻编辑每日新闻-生物技术的新研究-生物信息学是一篇报道的主题。根据NewsRx记者从中国天津发回的新闻报道,研究表明:“在原发性和晚期肿瘤中发现Ca NCER相关成纤维细胞(CAFs)。它们主要通过与肿瘤微环境中其他类型细胞的复杂机制参与肿瘤的进展。”新闻记者引用天津医科大学第二医院的一篇研究报道:“然而,膀胱癌中主要成纤维细胞相关基因(FRG)仍有待进一步研究,缺乏一种用于膀胱癌进展和免疫治疗评估的综合预测模型或分子亚型。”通过对膀胱癌单细胞RNA序列数据的分析,确定了膀胱癌CAF相关基因,并利用大量转录组数据和基因结构对其进行了表征。采用10种机器学习算法确定标志性FRG,构建FRG指数(FRGI)及其亚型,进一步建立分子亚型结合CD8+T细胞预测预后及免疫治疗反应,采用大规模SCRNA序列筛选54例BLCA相关的D FRG,建立3基因FRG指数(FRGI),FRG指数高则预后差。FRGI结合临床变量构建了一个列线图,该列线图对膀胱癌的预后有较高的预测能力。此外,将BLCA数据集分为成纤维细胞热型和冷型两种亚型,在5个独立的BLCA队列中,成纤维细胞热型比冷型表现更差,这两种类型中多种肿瘤相关标志通路明显丰富。然后,结合CD8+T细胞的FRG信号和活性,建立了4个CD8-FRG亚型,在多个独立数据集上对膀胱癌的预后和免疫治疗反应进行了预测。CD8-FRG亚型的表观遗传改变为膀胱癌的治疗提供了一种潜在的联合策略。

Abstract

By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Biotechnology - Bioinf ormatics is the subject of a report. According to news reporting originating in Tianjin, People’s Republic of China, by NewsRx journalists, research stated, “Ca ncer-associated fibroblasts (CAFs) are found in primary and advanced tumours. Th ey are primarily involved in tumour progression through complex mechanisms with other types of cells in the tumour microenvironment.” The news reporters obtained a quote from the research from the Second Hospital o f Tianjin Medical University, “However, essential fibroblasts-related genes (FRG ) in bladder cancer still need to be explored, and there is a shortage of an ide al predictive model or molecular subtype for the progression and immune therapeu tic assessment for bladder cancer, especially muscular-invasive bladder cancer b ased on the FRG. CAF-related genes of bladder cancer were identified by analyzin g single-cell RNA sequence datasets, and bulk transcriptome datasets and gene si gnatures were used to characterize them. Then, ten types of machine learning alg orithms were utilized to determine the hallmark FRG and construct the FRG index (FRGI) and subtypes. Further molecular subtypes combined with CD8+ T-cells were established to predict the prognosis and immune therapy response. 54 BLCA-relate d FRG were screened by large-scale scRNAsequence datasets. The machine learning algorithm established a 3-genes FRG index (FRGI). High FRGI represented a worse outcome. Then, FRGI combined clinical variables to construct a nomogram, which shows high predictive performance for the prognosis of bladder cancer. Furthermo re, the BLCA datasets were separated into two subtypes - fibroblast hot and cold types. In five independent BLCA cohorts, the fibroblast hot type showed worse o utcomes than the cold type. Multiple cancer-related hallmark pathways are distin ctively enriched in these two types. In addition, high FRGI or fibroblast hot ty pe shows a worse immune therapeutic response. Then, four subtypes called CD8-FRG subtypes were established under the combination of FRG signature and activity o f CD8+ T-cells, which turned out to be effective in predicting the prognosis and immune therapeutic response of bladder cancer in multiple independent datasets. Pathway enrichment analysis, multiple gene signatures, and epigenetic alteratio n characterize the CD8-FRG subtypes and provide a potential combination strategy method against bladder cancer.”
