Abstract

Background: Exploring the potential of BOLA3-DT as a diagnostic biomarker in prostate cancer.

Methods: Expression of the lncRNA BOLA3-DT was analyzed between normal and tumor samples in the GDC TCGA PRAD (Genomic Data Commons: The Cancer Genome Atlas Prostate Adenocarcinoma Collection) dataset. Disease progression-related clinicopathological parameters such as serum PSA level (ng/ml) and Gleason score were associated with the expression of BOLA3-DT using the same GDC TCGA PRAD dataset. To validate these findings, the expression of BOLA3-DT was checked in our sample set of 15 PCa (prostate cancer) and 15 BPH (benign hypertrophy of the prostate) patients.

Results: In the GDC TCGA PRAD dataset, the expression of the lncRNA BOLA3-DT was significantly downregulated in prostate cancer tissue samples (n = 492) compared to adjacent normal (n = 52; p < 0.0001), and, there was a significant negative correlation between the expression of the lncRNA BOLA3-DT and the serum PSA level (p < 0.01). However, no significant association was found between the lncRNA BOLA3-DT expression and the Gleason score (p > 0.05). In this study, it was found that BOLA3-DT was downregulated in PCa tissue samples compared to BPH samples (p > 0.05). In the GDC TCGA PRAD dataset, it was revealed that BOLA3-DT could serve as an excellent diagnostic marker with a sensitivity of 86.9% and a specificity of 84.6% (AUC-0.916).

Conclusion: LncRNA BOLA3-DT, a novel long non-coding RNA, was found to be downregulated in prostate cancer. The expression of the lncRNA BOLA3-DT can serve as a diagnostic marker in prostate cancer.
