(Submitter supplied) Tumorigenesis is characterised by changes in transcriptional regulation and the androgen receptor (AR) has been identified as a key driver in prostate cancer. In this study, we show that the hexosamine biosynthetic pathway (HBP) genes are overexpressed in clinical prostate cancer and androgen-regulated in cell-lines. HBP senses metabolic status of the cell and produces an essential substrate for O-GlcNAc transferase (OGT), which regulates target proteins via glycosylation. more...

(Submitter supplied) O-GlcNAc transferase (OGT) is overexpressed in aggressive prostate cancer. Here, we employed ChIP-seq to map chromatin-bound O-GlcNAc loci in prostate cancer cells and discovered that these overlap with sites of active transcription and MYC binding. Using RNA-seq, we show that inhibition of OGT promotes MYC-dependent transcriptional repression of mRNAs involved in G1-S transition. O-GlcNAc ChIP-seq regions are highly enriched to transcription start sites and identify the ‘GFY’-motif. more...

(Submitter supplied) O-GlcNAc transferase (OGT) is a nutrient-sensitive glycosyltransferase that is overexpressed in prostate cancer, the most common cancer in males. We recently developed specific and potent inhibitor targeting this enzyme, and here we report a synthetic lethality screen using this compound. Our screen identified pan-cyclin-dependent kinase (CDK) inhibitor AT7519 as lethal in combination with OGT inhibition. more...

(Submitter supplied) Following androgen ablation therapy (AAT), the vast majority of prostate cancer patients develop treatment resistance with a median time of 18-24 months to disease progression. To identify molecular targets that aid in prostate cancer cell survival and contribute to the androgen independent phenotype, we evaluated changes in LNCaP cell gene expression during 12 months of androgen deprivation. At time points reflecting critical growth and phenotypic changes, we performed Affymetrix expression array analysis to examine the effects of androgen deprivation during the acute response, during the period of apparent quiescence, and during the emergence of highly proliferative, androgen-independent prostate cancer cells (LNCaP-AI). more...

(Submitter supplied) In order to dissect the contribution of MYC to prostate cancer development, we overexpressed MYC in RWPE-1 cells and knocked down MYC in LNCaP cells. We performed RNA-seq on those cells. In the LNCaP cells only, we also performed ChIP-seq against MYC, H3K27ac, H3K27me3, and RNAP2.

(Submitter supplied) Human glioma pathogenesis-related protein 1 (GLIPR1) and its mouse counterpart, Glipr1 are downregulated in prostate cancer (PCa) and other malignant cell lines, owing partly to methylation in the gene’s regulatory region. Loss of Glipr1 function predisposed mice to tumorigenesis. Restoration of GLIPR1 expression in prostate cancer cells and other malignant cells led to growth suppression and/or apoptosis. more...

(Submitter supplied) The goal of this study was to determine how genetic alterations to AR inhibition-maintained prostate cancer cells alters transcriptional programs. We explored how MYC overexpression alters the transcriptional program of 16D cells maintained in enzalutamide for at least 2 months (LTenza) by transducing LTenza 16D cells with control (FUCRW) or MYC. To explore the effect of RB1 and TP53, we generated LTenza 16D cells with knockdown of RB1 and/or TP53 and compared these lines to control-transduced (shScr) LTenza 16D cells. more...

(Submitter supplied) The goal of this study was to determine how androgen receptor inhibition alters transcriptional programs in castration-resistant prostate cancer cells. 16D castration-resistant prostate cancer cells were grown in the presence of 10 micromolar enzalutamide for 24, 48, 96, 144 hours or for more than 2 months (long-term). Analysis shows that androgen receptor target genes are reduced with enzalutamide while metabolic genes are also differentially expressed.

Targeting the AR has a remarkable therapeutic index and represents a near-universal driver and therapeutic vulnerability in metastatic prostate cancer. Though most approaches directed toward the AR focus on inhibiting AR signaling, laboratory and now clinical data have shown that high dose, supraphysiological androgen treatment (SPA), results in growth repression and improved out-comes in subsets of prostate cancer patients. more...
