MetabolomicsSpermine is a natural suppressor of AR signaling in castration-resistant prostate cancer
In castration-resistant prostate cancer (CRPC), clinical response to androgen receptor (AR) antagonists is limited mainly due to AR-variants expression and restored AR signaling. The metabolite spermine is most abundant in prostate and it decreases as prostate cancer progresses, but its functions re...

GenomicsPersistent androgen receptor-mediated transcription in castration-resistant prostate cancer under androgen-deprived conditions
The androgen receptor (AR) is a ligand-inducible transcription factor that mediates androgen action in target tissues. Upon ligand binding, the AR binds to thousands of genomic loci and activates a cell-type specific gene program. Prostate cancer growth and progression depend on androgen-induced AR ...

TranscriptomicsIdentification of EP4 as a Potential Target for the Treatment of Castration-Resistant Prostate Cancer Using a Novel Xenograft Model
More effective therapeutic approaches for castration-resistant prostate cancer (CRPC) are urgently needed, thus reinforcing the need to understand how prostate tumors progress to castration resistance. We have established a novel mouse xenograft model of prostate cancer, KUCaP-2, which expresses the...

TranscriptomicsSRRM4 Expression and the Loss of REST Activity May Promote the Emergence of the Neuroendocrine Phenotype in Castration-Resistant Prostate Cancer
The neuroendocrine (NE) phenotype is associated with the development of metastatic castration-resistant prostate cancer (CRPC). Our objective was to characterize the molecular features of the NE phenotype in CRPC. Expression of chromogranin A (CHGA), synaptophysin (SYP), androgen receptor (AR), and ...

TranscriptomicsLNCaP Atlas: Gene expression associated with in vivo progression to castration-recurrent prostate cancer
Background: There is no cure for castration-recurrent prostate cancer (CRPC) and the mechanisms underlying this stage of the disease are unknown. Methods: We analyzed the transcriptome of human LNCaP prostate cancer cells as they progress to CRPC in vivo using replicate LongSAGE libraries. We refer ...

TranscriptomicsGene expression data from gastrocnemius muscle (m.Gas) in young adult mice
This study examined the effects of castration and testosterone replacement on global differential gene transcription in the gastrocnemius muscle (m.Gas) in young adult mice over 14-days. Each of the 3 treatment groups was composed of 3 independent biological replicates, totaling 9 arrays. Equal amou...

TranscriptomicsGene Expression in Castration-Resistant C4-2 Cells after AR Knockdown
Prostate cancer is the most common, lethal malignancy in men. Although androgen withdrawal therapies are used to treat advanced disease, progression to a castration-resistant, end-stage is the usual outcome. In this study, the tested hypothesis was that the androgen receptor remains essential for th...

ProteomicsGNL3 orchestrates AR transcriptional programs to drive castration-resistant prostate cancer and immune evasion
Androgen receptor (AR) signaling is a primary oncogenic driver of castration-resistant prostate cancer (CRPC), yet the mechanism remains incompletely understood. Dysregulation of the AR co-regulatory network has emerged as a key driver of castration resistance. To identify AR-interacting proteins li...

TranscriptomicsHes6 expression is controlled by c-Myc and the AR to promote E2F1 activity and poor outcome in castrate-resistant prostate cancer (xenografts)
Hes6 is a transcription co-factor that is associated with stem cell characteristics in neural tissue, but its role in cancer remains uncertain. Here we show that Hes6 is controlled by c-Myc and the AR and can drive castration resistance in xenografts of the androgen-dependent LNCaP prostate cancer c...
