In addition, lncRNA-ATB (Li et al., 2018), metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) and lncRNA H19 (Jin et al., 2016; Li et al., 2020; Huang et al., 2021), which are abnormally expressed in TNBC, may provide a less invasive diagnostic procedure to reveal immunological insight of breast cancer. Here, H19 is linked to breast cancer.
