METTL3 May Regulate Testicular Germ Cell Tumors Through EMT and Immune Pathways.

Abstract:

:Testicular germ cell tumors (TGCTs) are highly prevalent in young men aged 20-40 years and are one of the most common lethal solid tumors in men of this age. Due to the current unclear mechanism of tumor development, there is a lack of effective treatment, and therefore in-depth research of the molecular mechanism of the occurrence and development of TGCT and the search for suitable and effective therapeutic targets and molecular markers are of great significance for achieving effective treatment. METTL3 is a very important methylase, which has been implicated in the progression of many cancers, but the role of METTL3 in TGCT has not been fully elucidated. In this article, we found that METTL3 expression was significantly downregulated in TGCT tissues, and patients with low expression levels had lower overall survival and relapse-free survival rates. After overexpressing METTL3, cell proliferation, invasion, and migration ability significantly increased, while influencing the expression of epithelial-mesenchymal transition (EMT)-related proteins. In addition, we observed that the expression level of METTL3 positively correlated with molecular markers and infiltration level of CD8+ and CD4+ T cells and natural killer cells. In sum, our findings identified that METTL3 can be used as an independent prognostic marker in patients with TGCT. METTL3 participates in the proliferation, migration, and invasion of TGCT cells by regulating the expression of EMT-related genes and may also play a role in activating the tumor immune response in TGCT.
