TUSC3 and gastric cancer: Then, we conducted Pearson correlation analysis to analyze the correlations of LncRNA MIR503HG, miR-224-5p and TUSC3 mRNA levels in GC tissues, and the results showed that miR-224-5p negatively correlated with LncRNA MIR503HG (Figure 3G) and TUSC3 mRNA (Figure 3H), but LncRNA MIR503HG and TUSC3 mRNA showed positive relevance in GC tissues (Figure 3I).
