LRP1 and cancer: Across all cancer types, the mRNA level of LRP1 analysis showed a positive correlation with tumour purity in several cancers: KIPAN (r =   0.590, p <  0.001), BRCA (r =   0.570, p <  0.001), BLCA (r  =  0.540, p  <  0.001), KIRC (r  =  0.45, p  <  0.001), LUAD (r  =  0.450, p <  0.001), THCA (r  =  0.390, p <  0.001), KIRP (r =   0.500, p <  0.001), PAAD (r =  0.600, p <  0.001), PRAD (r =   0.370, p <  0.001), and OC (r  =  0.250, p <  0.001) (Figure S17A–J).
