Therefore, in the current study, the expression profiles of 20 lncRNAs (H19, CCAT1, CCAT2, UCA1, SPRY4‐IT1, AK058003, Z38, MVIH, XIST, PANDAR, GAS5, ITGB2‐AS1, MEG3, AC026904.1, ZFAS1, NKILA, EPB41L4A‐AS2, FGF14‐AS2, NBAT1, BC040587) in blood samples of breast cancer patients and healthy females investigated by qRT‐PCR. This evidence concerns the gene CLDND1 and breast cancer.
