Exosomal lncRNA like MALAT1 (Liu J. et al., 2021), growth arrest-specific 5 (GAS5) (Patel et al., 2022), H19 (Wang et al., 2020), HOTAIR (Yang et al., 2019), small ubiquitin-like modifier 1 SUMO1 pseudogene 3 (SUMO1P3) (Li et al., 2021b) and X-inactive specific transcript (XIST) (Lan et al., 2021) were previously shown upregulated in the blood, lung and breast tissues of cancer patients (Li et al., 2021b). This evidence concerns the gene H19 and cancer.
