Abstract

Non-small cell lung cancer (NSCLC) is the most common and deadly type of lung cancer, and its poor prognosis is closely related to the complex interactions of the tumor microenvironment. Through methylation analysis of tumor tissue samples from NSCLC patients, combined with high-throughput sequencing technology, the methylation status and structural characteristics of mRNA molecules were studied. Bioinformatics tools were used to analyze the regulatory effects of methylation modification on mRNA expression and genes associated with the tumor microenvironment. The results showed that the methylation level of specific mRNA was significantly correlated with the expression changes of tumor microenvironment-related factors. In addition, methylation modification affected mRNA stability and translation efficiency, further altering the metabolic activity and immune escape capacity of tumor cells. The results showed that mRNA with high methylation level was significantly associated with poor prognosis. Methylation modification profoundly affects the tumor microenvironment and prognosis of non-small cell lung cancer by altering the structure and function of mRNA molecules.
