Animal and cell culture studies have showed that boron and its derivatives may be promising anticancer agents in prostate cancer treatment. Thus, DU145 cells were treated with disodium pentaborate decahydrate (DPD) for 24, 48, and 72 h in order to investigate the inhibitor effect and mechanisms of DPD. Then, cell proliferation, telomerase enzyme activity,(More)
It has been reported that NKX3.1 an androgen-regulated homeobox gene restricted to prostate and testicular tissues, encodes a homeobox protein, which transcriptionally regulates oxidative damage responses and enhances topoisomerase I re-ligation by a direct interaction with the ATM protein in prostate cells. In this study, we aimed to investigate the role(More)
As the molecular mechanism of β-catenin deregulation is not well understood, and stabilized β-catenin is known to translocate into the nucleus and activate genes for proliferation, a novel regulatory factor, hematological and neurological expressed 1 (HN1), for Akt-GSK3β-β-catenin axis is reported here. In our studies, HN1 gene structure was characterized.(More)
As a link between inflammation and cancer has been reported in many studies, we established an in vitro model of prostatic inflammation to investigate the loss of androgen receptor (AR)-mediated signaling in androgen responsive prostate cell lines. First, the U937 monocyte cell line was differentiated into macrophages using phorbol acetate (PMA), and cells(More)
NKX3.1 is an androgen-regulated homeobox gene that encodes a tissue-restricted transcription factor, which plays an important role in the differentiation of the prostate epithelium. Thus, the role of NKX3.1 as a functional topoisomerase I activity enhancer in cell cycle regulation and the DNA damage response (DDR) was explored in prostate cancer cell lines.(More)
HOXB13 is a homeobox protein that is expressed in normal adult prostate and colon tissues; however, its deregulated expression was evidenced in various malignancies. To characterize the putative role of HOXB13 in cell cycle progression, we performed overexpression and siRNA-mediated knockdown studies in PC-3 and LNCaP cells. Immunohistochemistry (IHC)(More)
We recently reported that hematological and neurological expressed 1 (HN1) is a ubiquitously expressed, EGF-regulated gene. Expression of HN1 in prostate cell lines down-regulates PI3K-dependent Akt activation. Here, we investigate whether HN1 is regulated by androgens through the putative androgen response elements (AREs) found in its promoter. Knockdown(More)
