Normalising smLRP1 expression to LRP1 and referring its ratio in tumour cell lines to that of corresponding healthy tissues (ratio smLRP1/LRP1) showed increased expression level of splice variant smLRP1 relative to LRP1 in U87-MG (p<0.01), 1321N1 (p<0.001), A549 (p<0.001), and HT-29 (p<0.05) compared to corresponding healthy human tissue. Here, LRP1 is linked to neoplasm.
