We also found that those differentially expressed long ncRNAs have significant correlations (r≥0.4 and p<0.05) with some previously identified breast cancer or lung cancer related genes (Tables S1 and S2), such as long ncRNA “Pred35111” was significantly correlated with LEPR (r = 0.66, p =  ), and LEPR has reported in several studies that it involves in the pathogenesis of breast cancer [44]–[47]. Here, LEPR is linked to breast carcinoma.
