Long noncoding RNA Lymph Node Metastasis Associated Transcript 1 (LNMAT1), overexpressed in BlCa tissues comparing with normal adjacent tissues, can directly interact with heterogeneous nuclear ribonucleoprotein L (hnRNPL), resulting in an increase of the H3 lysine four trimethylation (H3K4me3) of the CCL2 promoter (Chen et al., 2018). Here, CCL2 is linked to bladder transitional cell carcinoma.
