In incurable castration-resistant prostate cancer (CRPC), resistance to the novel androgen receptor (AR) antagonist enzalutamide is driven mainly by AR overexpression. Here we report that the expression of interferon regulatory factor 8 (IRF8) is increased in primary prostate cancer but decreased in CRPC compared with normal prostate tissue. Decreased expression of IRF8 positively associated

This reexpression is associated with a 2018-09-14 · Background Androgen receptor (AR) is expressed in 60%~ 70% oestrogen receptor (ER)-negative breast cancer (BC) cases and promotes the growth of this cancer subtype. Expression of prostate-derived Ets factor (PDEF), a transcription factor, is highly restricted to epithelial cells in hormone-regulated tissues. MYC and its negative regulator MAD1 play an important role in BC progression To establish whether β-catenin's accumulation in the cytoplasm and nuclei of AR-negative human prostate cancer cells was an isolated (or low-incidence) occurrence in MDA prostate cancer 118b cells, we stained sections from 27 archived CRPC bone metastases (excluding the case of origin of the MDA prostate cancer 118 xenograft) with antibodies against AR and β-catenin in consecutive sections. 2019-08-06 · Our data show that AR-expressing prostate cancer cells (LNCaP, 22Rv1, and VCaP) are more sensitive to CWP232291 than AR-negative prostate cancer cells (PC3 and DU145). Given the role of AR in CRPC, these results suggest that targeting WNT signaling may be a more effective treatment for AR-positive than AR-negative CRPC through the concurrent disruption of β-catenin and AR signaling. Prostate cancer cells exhibiting a transcriptionally active AR-signaling complex (LNCaP, 22Rv1) were more susceptible to the growth-inhibitory effects than the AR-negative PC-3 cells.

Exposure of AR-negative prostate cancer cell lines to 5-aza-2' deoxycytidine, a demethylating agent, induces the reexpression of AR RNA in DuPro and TSU-PR1. This reexpression is associated with a 2018-09-14 · Background Androgen receptor (AR) is expressed in 60%~ 70% oestrogen receptor (ER)-negative breast cancer (BC) cases and promotes the growth of this cancer subtype.

Accurately identify patients resistant to targeted therapies. For patients with metastatic castration-resistant prostate cancer (mCRPC), the Oncotype DX AR-V7 Nucleus Detect Test lets you quickly and confidently determine the likely benefit of androgen receptor (AR)-targeted therapies, like Abiraterone (Zytiga ®), Enzalutamide (Xtandi™), and Apalutamide (Erleada™).

( Fig. 6 ). The ability to identify prostate cancer cells with a modified AR response, which are anticipated to be less sensitive to androgen deprivation therapy (ADT), is of potential utility considering the inter- and intratumoral heterogeneity of prostate cancer ( 4–6 ). Most men who present with metastatic prostate cancer have markedly elevated serum levels of PSA. However, approximately 1% of cases have serum PSA levels that are much lower than the tumour burden would suggest - so-called "PSA-Negative" tumours.

However, the ELL2 gene appears to be amplified in AR-negative neuroendocrine prostate tumors, suggesting a potential oncogenic role for ELL2 in AR-negative prostate cancer cells. In this study, we explored the potential function of ELL2 in PC-3 and DU145, two AR-negative prostate cancer cell lines.
