(Submitter supplied) The first aim of the study was to identify the genes regulated by the estrogen receptor alpha (ERa) in the normal mouse prostate, with and without the co-activation of the androgen receptor. The second objective was to decipher the changes in the estrogen and androgen responses in a tumoral context from prostate cancer-developping mice.

(Submitter supplied) MicroRNAs (miRNAs) regulate a wide range of cellular signaling pathways and biological processes in both physiological and pathological states such as cancer. We have previously identified miR-135b as a direct regulator of androgen receptor (AR) protein level in prostate cancer (PCa). We wanted to further explore the relationship of miR-135b to hormonal receptors, particularly estrogen receptor α (ERα). more...

Analysis of LNCaP prostate cancer (PCa) cells overexpressing miRNA-135b for up to 36 hours. LNCaP cells express the androgen receptor (AR). MiRNA-135b overexpression in AR+ PCa cells results in slower growth compared to AR knockdown. Results provide insight into the basis of this slower growth.

(Submitter supplied) Background: Breast (BCa) and prostate (PCa) cancers are hormone receptor (HR)-driven cancers. Estrogen receptor alpha (ERa) is overexpressed in 70% of diagnosed BCa patients and androgen receptor (AR) is overexpressed in 80-90% of diagnosed PCa patients. Thus, BCa and PCa patients are given therapy that reduces hormone levels or directly blocks HR activity; but most patients eventually develop treatment resistance. more...

(Submitter supplied) In immunosurveillance, bone-derived immune cells infiltrate the tumor and secrete inflammatory cytokines to destroy cancer cells. However, cancer cells have evolved mechanisms to usurp inflammatory cytokines to promote tumor progression. In particular, the inflammatory cytokine, interleukin-1 (IL-1), is elevated in prostate cancer (PCa) patient tissue and serum and promotes PCa bone metastasis. IL-1 also represses androgen receptor (AR) accumulation and activity in PCa cells, yet the cells remain viable; suggesting that IL-1 may also contribute to AR-targeted therapy resistance. more...

(Submitter supplied) Whether the nuclear fraction of mTOR plays a role in prostate cancer (PCa) and can participate in direct transcriptional crosstalk with the androgen receptor (AR) is as yet unknown. The intersection of gene expression, DNA binding-events, and metabolic studies uncovered the existence of a nuclear mTOR-AR transcriptional axis dictating the metabolic rewiring and nutrient usage of PCa cells. In human clinical specimens, nuclear localization of mTOR was significantly associated with metastasis and castration-resistant PCa (CRPC), correlating with a sustained metabolic gene program governed by mTOR in that context. more...

(Submitter supplied) Prostate epithelial cells depend on androgens for survival and function. In early prostate cancer, besides survival, androgens also regulated tumor growth, which is exploited by androgen ablation/ blockade therapies in metastatic disease. The aim of the present study was to characterize the role of the androgen receptor pathway in prostate cancer progression and to identify potential disease markers. more...

(Submitter supplied) While protein arginine methyltransferases (PRMTs) and PRMT-catalyzed protein methylation have been well-known to be involved in a myriad of biological processes, their roles in carcinogenesis, particularly in estrogen receptor alpha (ERa)-positive breast cancers, remain incompletely understood. Here we focused on investigating PRMT4 (also called coactivator associated arginine methyltransferase 1, CARM1) due to its high expression and the associated poor prognosis in ERa-positive breast cancers. more...

(Submitter supplied) In this study, we found the efficacy of AR-targeting drugs largely depended on the context of AR (Androgen Receptor) and ERα (Estrogen Receptor) status. Enzalutamide, an AR blocker, had a better inhibition effect on ER+ cells with lower AR expressed compared to cells expressed higher AR. To explore the mechanism of action of Enzalutamide, we performed ChIP-seq to illustrate the AR and ER genomic bindings after Enzalutamide treatment in both MCF7 and MCF7 with AR over expression (AROE) cells. more...

(Submitter supplied) Heat shock factor 1 (HSF1) is a key regulator of transcriptional responses to proteotoxic stress. It has been recently linked to signaling of estrogen via ESR1. To study the cooperation of HSF1 and ESR1 in the transcriptional response to estrogen, we established estrogen receptor (ER)-positive breast cancer cell lines with reduced HSF1 levels using specific shRNA or CRISPR/Cas9 approach. HSF1 deficiency led to the inhibition of the mitogenic effect of estrogen in MCF7 and T47D cells. more...
