Prominin 1 (PROM1) is considered a biomarker for cancer stem cells, although its biological role is unclear. Prominin 2 (PROM2) has also been associated with certain cancers. However, the prognostic value of PROM1 and PROM2 in cancer is controversial. Here, we performed a systematic data analysis to examine whether prominins can function as prognostic markers in human cancers. The expression of prominins was assessed and their prognostic value in human cancers was determined using univariate and multivariate survival analyses, via various online platforms. We selected a group of prominent functional protein partners of prominins by protein-protein interaction analysis. Subsequently, we investigated the relationship between mutations and copy number alterations in prominin genes and various types of cancers. Furthermore, we identified genes that correlated with PROM1 and PROM2 in certain cancers, based on their levels of expression. Gene ontology and pathway analyses were performed to assess the effect of these correlated genes on various cancers. We observed that PROM1 was frequently overexpressed in esophageal, liver, and ovarian cancers and its expression was negatively associated with prognosis, whereas PROM2 overexpression was associated with poor overall survival in lung and ovarian cancers. Based on the varying characteristics of prominins, we conclude that PROM1 and PROM2 expression differentially modulates the clinical outcomes of cancers.

PROM1 和 PROM2 表达差异调节癌症的临床预后:多组学分析。



Prominin 1 (PROM1) 被认为是癌症干细胞的生物标志物,尽管其生物学作用尚不清楚。 Prominin 2 (PROM2) 也与某些癌症有关。然而,PROM1 和 PROM2 在癌症中的预后价值存在争议。在这里,我们进行了系统的数据分析,以检查突出蛋白是否可以作为人类癌症的预后标志物。通过各种在线平台,使用单变量和多变量生存分析评估了 prominin 的表达,并确定了它们在人类癌症中的预后价值。我们通过蛋白质-蛋白质相互作用分析选择了一组突出的突出蛋白功能蛋白伙伴。随后,我们研究了 prominin 基因的突变和拷贝数改变与各种类型的癌症之间的关系。此外,我们根据某些癌症中 PROM1 和 PROM2 的表达水平鉴定了与 PROM1 和 PROM2 相关的基因。进行基因本体论和通路分析以评估这些相关基因对各种癌症的影响。我们观察到 PROM1 在食管癌、肝癌和卵巢癌中频繁过度表达,其表达与预后呈负相关,而 PROM2 过度表达与肺癌和卵巢癌的总体生存率较差相关。根据 prominin 的不同特征,我们得出结论,PROM1 和 PROM2 表达对癌症的临床结果有不同的调节作用。
