Abstract

Atraric acid (AA) is a natural compound used for treatment of benign prostate hyperplasia. This agent has an anti-androgen receptor (AR) activity suppressing androgen-mediated neo-angiogenesis. In the current study, we have analyzed the transcriptome data of prostate cancer cells treated with AA (GSE172205) to find differentially expressed genes (DEGs) with an especial focus on lncRNAs and miRNAs. Then, we assessed expression of the differentially expressed lncRNAs (DElncRNAs) in available online sources to validate their association with prostate cancer and their importance in the determination of survival of patients with this type of cancer. We obtained 1871 DEGs, including 914 down-regulated DEGs (such as DAB1 and CD200) and 957 up-regulated DEGs (such as CHRNA2 and TRGC1), and 25 DElncRNAs, including 15 down-regulated DElncRNAs (such as LINC00639 and HOTTIP) and 10 up-regulated DElncRNAs (such as LINC00844 and LINC00160), and one up-regulated DEmiRNA (MIR29B1). The main pathways for the down-regulated genes and the up-regulated genes were Axon Guidance and Steroid BioSynthesis, respectively. Taken together, AA has been found to affect expression of several lncRNAs which are possibly involved in the pathoetiology of prostate cancer.
