This is also supported by the observation of suppressive miR-4732-3p being discarded from NSCLC cells into the bloodstream via selective sorting by hnRNPK to fucosylated exosomes, leading to a significant elevation in the level of serum LCA-exosomal miR-4732-3p in our pilot study (20). This evidence concerns the gene HNRNPK and non-small cell lung carcinoma.
