Abstract

Background: TMEM189 is a recently discovered transmembrane protein involved in ether glycerophospholipid synthesis and ferroptosis regulation. However, its role in tumors are not well understood.

Objective: To elucidate the oncogenic effects and prognostic values of TMEM189 in tumors.

Methods: We performed a pan-cancer analysis of TMEM189 using various databases, bioinformatics and statistical tools, and tissue microarray analysis.

Results: TMEM189 is generally upregulated in tumors compared to normal tissues. High TMEM189 expression is linked to reduced promoter methylation. TMEM189 exhibits a negative correlation with immunogenic markers, immune cell infiltration, and expression of immune checkpoint genes (ICGs) in most cancers, implicating its immunosuppressive role in tumor microenvironments (TME). The interacting and similar genes with TMEM189 were involved in hotspot signaling pathways in pan-cancer. TMEM189 overexpression is usually associated with poor prognosis, especially an independent prognostic risk factor for BLCA, BRCA, LUAD, MESO, LIHC and SKCM.

Conclusion: TMEM189 is overexpressed and exerts immunosuppressive effects in many tumors with a significant association with poor prognosis, suggesting its potential as a therapeutic target in cancer treatment.

解码铁突变基因 TMEM189 的表达、免疫相关性和预后价值：泛癌症分析。

背景：TMEM189是最近发现的一种跨膜蛋白，参与醚甘油磷脂合成和铁变态调节。然而，人们对其在肿瘤中的作用还不甚了解：目的：阐明 TMEM189 在肿瘤中的致癌作用和预后价值：方法：我们利用各种数据库、生物信息学和统计学工具以及组织芯片分析对 TMEM189 进行了泛癌症分析：结果：与正常组织相比，TMEM189在肿瘤中普遍上调。TMEM189的高表达与启动子甲基化减少有关。在大多数癌症中，TMEM189与免疫原标志物、免疫细胞浸润和免疫检查点基因（ICGs）的表达呈负相关，这表明它在肿瘤微环境（TME）中发挥着免疫抑制作用。与TMEM189相互作用和相似的基因参与了泛癌症的热点信号通路。TMEM189过表达通常与预后不良有关，尤其是BLCA、BRCA、LUAD、MESO、LIHC和SKCM的独立预后风险因素：结论：TMEM189在许多肿瘤中过表达并发挥免疫抑制作用，与预后不良有显著相关性，这表明它有可能成为癌症治疗的靶点。
