Expression, prognosis value, and immune infiltration of lncRNA ASB16-AS1 identified by pan-cancer analysis
Long-chain non-coding RNA ASB16-AS1 has been proven to be an oncogene for many cancer types. However, the relationship between ASB16-AS1 and immunity is still under studied. This study aims to explore the expression and prognostic potential of ASB16-AS1, and to visualize the relationship between ASB...

| Sumario: | Long-chain non-coding RNA ASB16-AS1 has been proven to be an oncogene for many cancer types. However, the relationship between ASB16-AS1 and immunity is still under studied. This study aims to explore the expression and prognostic potential of ASB16-AS1, and to visualize the relationship between ASB16-AS1 expression and immune infiltration in pan-cancer. We clarified ASB16-AS1 expression patterns in pan-cancer and its relationship with prognosis through multi-platform and multi-database sources (TCGA, GEO, GTEx, ArrayExpress, and SRA), and verified the function of ASB16-AS1 in liver hepatocellular carcinoma (LIHC). Then, a variety of immune cell content evaluation methods were used to mutually verify the correlation between ASB16-AS1 and immune infiltration. Finally, the relationships between ASB16-AS1 and some molecular characteristics (immune checkpoints, tumor mutation burden, microsatellite instability, oncogenic signaling pathways) were further explored. In terms of comprehensive analysis, compared with non-tumor tissues, ASB16-AS1 was highly expressed in tumor tissues, and indicated the value of poor prognosis in multiple cancer types. Functional assays, such as CCK8 assay, transwell assay and wound scratch assay, verified that high ASB16-AS1 expression promoted tumor progression in LIHC. ASB16-AS1 was positively correlated with B cells, T cell CD4+ and T cell CD8+ in most cancer types, and negatively correlated with macrophages, dendritic cells and neutrophils in some cancer types, especially in neutrophils. In addition, there were different interaction modes between ASB16-AS1 and molecular features, such as the relationship with oncogenic signaling pathways, showing that the high ASB16-AS1 expression was related to alterations in oncogenic signaling pathways. Our study emphasizes that ASB16-AS1 is a potential pan-cancer prognostic marker, whichs is associated with the immune infiltration in multiple cancer types. |
