Correlation analysis of the expression levels of HIF1A and LINC01138 and LINC01605 in ccRCC tissue samples revealed that the two GRLs were significantly correlated with HIF1A, LINC01138 was negatively correlated with HIF1A, and LINC01605 was positively correlated with HIF1A (Figure 5B). The gene discussed is HIF1A; the disease is nonpapillary renal cell carcinoma.
