Adenocarcinoma of the lung (LUAD) is a common subtype of lung cancer with a poor prognosis and high incidence worldwide. In recent years, increasing evidence has demonstrated that IGF2BP3 plays an important role in the initiation and progression of many types of human cancer. However, the mechanism of IGF2BP3 in LUAD is still unclear.So we performed pancancer analysis of IGFBP3 expression and prognosis using The Cancer Genome Atlas (TCGA) and UALCAN data. Then, we identified the microRNA and lncRNA that lead to the overexpression of IGFBP3 by using a series of in silico analyses, including expression analysis, correlation analysis and survival expression. Finally, we use TIMER to analyze the correlation of IGF2BP3 expression level with immune cell infiltrating level or immune checkpoint expression level in LUAD. Our study proved that IGF2PB3, upstream lncRNA, and VIRMA can impact m6A modification in LUAD, thus impacting prognosis, and the VIRMA /LINC00665 /has-let-7c-5p /IGF2BP3 axis is also related to tumor immune cells in LUAD. However, these results should be validated by much more clinical trials in future.
