SLC6A8 and non-small cell lung carcinoma: To explore the lncRNA-miRNA-mRNA networks that regulate the expression of SLC6A8 in NSCLC, the expression matrix of miRNAs from the TCGA database combined with SLC6A8-related miRNAs from the Starbase database (miRNA=41) was extracted to construct a miRNA-mRNA co-expression network (Figure 3A).
