As a result, it is considered that they may play an important role in different cancers. With regard to the high prevalence of breast cancer and the role of lncRNA, the present study aimed at investigating the expression of various lncRNAs. Method: Fresh tissues were obtained from operating rooms of Shariati, Khatamolanbia, and Milad Hospitals (Tehran, Iran) by a surgeon. A total of 45 tumor samples and 45 non-tumor samples (from the margin of tumor) were obtained from the same patients. Relative expression evaluation method was used in Real time PCR. Estrogenn receptor (ER), progesterone receptor (PR), and HER2 expression were analyzed using IHC analyses of each cell block. Results: Participants included 44 female and 1 male with the mean age ± SD of 50 ± 12.0 years (range: 23-74). A majority of participants (41/45) were Ductal carcinoma type. Our results showed significant expressions for CBR3-AS1 (P-value=0.0139), RAB6C-AS1 (P-value=0.0023), and ZEB2-AS1 (P-value=0.0289) in comparison with the healthy cells. ROC curve analysis for CBR3-AS1 LncRNA revaled sensitivity more than 70%. Conclusion: Although CBR3-AS1, RAB6C-AS1, and ZEB2-AS1 lncRNAs were found to have high expressions in the breast cancer cells, only CBR3-AS1 lncRNA has a high chance to be a breast cancer biomarker.  UR - https://journal.waocp.org/article_89761.html L1 - https://journal.waocp.org/article_89761_2f2cff64127c97e85461e7d4c71aa6d8.pdf ER -
