Transcription Levels of nicotinamide nucleotide transhydrogenase and Its Antisense in Breast Cancer Samples
Journal Title: Cell Journal(Yakhteh) - Year 2019, Vol 21, Issue 3
Abstract
Objective: To evaluate association of patients’ clinicopathological data with expression of nicotinamide nucleotide transhydrogenase (NNT) and naturally occurring antisense RNA of the same gene locus (NNT-AS1) in breast cancer samples. Materials and Methods: In the current case-control study, mean expressions of NNT and NNT-AS1 were assessed in 108 breast tissue samples including 54 invasive ductal carcinoma samples and 54 adjacent non-cancerous tissues (ANCTs) by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Results: NNT expression was not significantly different between tumor tissues and ANCTs. However, NNT-AS1 expression was significantly down-regulated in tumor tissues compared to ANCTs (expression ratio=0.51, P=0.01). NNT-AS1 expression was significantly higher in estrogen receptor (ER) negative samples, in comparison with ER positives (P=0.01). No considerable difference was found in the gene expressions between other subcategories of patients. Considerable correlations were detected between expression levels of these two genetic loci in both tumor tissues and ANCTs. Conclusion: In the current study, for the first time we simultaneously assessed expression of NNT and NNT-AS1 in breast cancer tissues. This study highlights association of ER status with dysregulation of NNT-AS1 in breast cancer tissues. Future researches are necessary to explore the function of this long non-coding RNA (lncRNA) in the pathogenesis of breast cancer.
