Aim:
MYC deregulation contributes to breast cancer development and progression. Deregulated expression levels of long non-coding RNAs (lncRNA) have been demonstrated to be critical players in development and/or maintenance of breast cancer. In this study we aimed to evaluate lncRNA expressions depending on MYC overexpression and knockdown in breast cancer cells.
Materials And Methods:
Cells were infected with lentiviral vectors by either knockdown or overexpression of c-MYC. LncRNA cDNA was transcribed from total RNA samples and lncRNAs were evaluated by qRT-PCR.
Results:
Our results indicated that some of the lncRNAs having tumor suppressor (GAS5, MEG3, lincRNA-p21) and oncogenic roles (HOTAIR) are regulated by c-MYC.
Conclusion:
We observed that c-MYC regulates lncRNAs that have important roles on proliferation, cell cycle and etc. Further studies will give us a light to identify molecular mechanisms related to MYC-lncRNA regulatory pathways in breast cancer.
