PURPOSE: Metastatic castration-resistant prostate cancer with low baseline prostate-specific antigen represents an early stage in the natural history of castration-resistant prostate cancer disease progression (low-volume disease), low prostate-specific antigen-producing disease, or disease less dependent on androgen receptor biology (high-volume disease). We analyzed outcomes in men with low prostate-specific antigen and high disease burden who received the oral androgen-receptor inhibitor enzalutamide in the PREVAIL study...

Canonical WNT signaling through Frizzled and LRP5/6 receptors is transduced to the WNT/β-catenin and WNT/stabilization of proteins (STOP) signaling cascades to regulate cell fate and proliferation, whereas non-canonical WNT signaling through Frizzled or ROR receptors is transduced to the WNT/planar cell polarity (PCP), WNT/G protein-coupled receptor (GPCR) and WNT/receptor tyrosine kinase (RTK) signaling cascades to regulate cytoskeletal dynamics and directional cell movement. WNT/β-catenin signaling cascade crosstalks with RTK/SRK and GPCR-cAMP-PKA signaling cascades to regulate β-catenin phosphorylation and β-catenin-dependent transcription...

Prostate Cancer (PCa) is a complex and heterogeneous disease. The androgen receptor (AR) and the signal transducer and activator of transcription 3 (STAT3) could be effective targets for PCa therapy. STAT3, a cytoplasmatic latent transcription factor, is a hub protein for several oncogenic signalling pathways and up-regulates the expression of numerous genes involved in tumor cell proliferation, angiogenesis, metastasis and cell survival. STAT3 activity can be modulated by several Post-Translational Modifications (PTMs) which reflect particular cell conditions and may be implicated in PCa development and progression...

MicroRNAs (miRs) are short and highly conserved non-coding RNAs molecules consisting of 18-25 nucleotides that regulate gene expression at post-transcriptional level by direct binding to complementary binding sites within the 3'untranslated region (3'UTR) of target mRNAs. New evidences have demonstrated that miRNAs play an important role in diverse physiological processes, including regulating cell growth, apoptosis, metastasis, drug resistance, and invasion. In chromosomes 11 and 22 of the miR-130 family, paralogous miRNA sequences, miR-130a and miR-130b are situated, respectively...

INTRODUCTION: For patients with oligometastatic recurrence of prostate cancer (PC), stereotactic body radiation therapy (SBRT) represents an attractive treatment option, as it is safe without major side effects. The aim of this study was to investigate the impact of SBRT in delaying the start of androgen deprivation therapy (ADT). PATIENTS AND METHODS: Forty-three patients treated with SBRT for oligometastatic recurrence (< 5 metastases) of hormone-sensitive PC, defined with [(18)F]fluoromethylcholine positron emission tomography/computed tomography were included...

Epithelial to mesenchymal transition (EMT) is an important prerequisite for metastasis to secondary organs. Interleukin-like EMT inducer (ILEI) protein has been shown to translationally upregulated during EMT and metastatic progression as a consequence of aberrant TGF-β signaling. Our initial evaluation of FAM3C (encoding ILEI) and ILEI expression in normal prostate (PCS-440-010) and prostate cancer cell lines (DU145, LNCaP, and PC3) revealed detectable protein expression in only LNCaP cell line even though all cell lines tested had comparable FAM3C expression...

BACKGROUND: Postoperative radiotherapy has an important role in the treatment of prostate cancer, but personalised patient selection could improve outcomes and spare unnecessary toxicity. We aimed to develop and validate a gene expression signature to predict which patients would benefit most from postoperative radiotherapy. METHODS: Patients were eligible for this matched, retrospective study if they were included in one of five published US studies (cohort, case-cohort, and case-control studies) of patients with prostate adenocarcinoma who had radical prostatectomy (with or without postoperative radiotherapy) and had gene expression analysis of the tumour, with long-term follow-up and complete clinicopathological data...

Purpose: Despite the efficacy of abiraterone, a CYP17A1 inhibitor, in metastatic castration-resistant prostate cancer (CRPC), nearly all patients develop resistance. The purpose of this phase II study was to evaluate mechanisms of resistance to more complete androgen synthesis inhibition with abiraterone and dutasteride.Experimental Design: Eligible patients with metastatic CRPC underwent a baseline metastasis biopsy. Patients received abiraterone and prednisone for two 4-week cycles. After this time, high-dose dutasteride (3...

INTRODUCTION: Early localisation of disease recurrence after definitive treatment of prostate cancer is vital to determine suitability for salvage treatment. Our aim was to further investigate the relationship between prostate specific antigen (PSA) level and detection of suspected cancer recurrence using (68 ) Ga-PSMA PET/CT in patients with biochemical recurrence after radical prostatectomy (RP) or radiotherapy, particularly at low PSA levels. METHODS: This retrospective single tertiary referral institution cohort study of men reviewed the results of (68 ) Ga-PSMA PET/CT scans for investigation of post RP and post radiotherapy PSA recurrence following primary treatment of prostate cancer...

The isoprenoid biosynthetic pathway (IBP) plays a critical role in providing substrates and enzymes necessary for the post-translational modification and thus activation of a number of proteins involved in prostate cancer metastasis. Previous work by our lab found novel compound disodium [(6Z,11E,15E)-9-[bis(sodiooxy)phosphoryl]-17-hydroxy-2,6,12,16-tetramethyheptadeca-2,6,11,15-tetraen-9-yl]phosphonate (GGOHBP), which inhibits the IBP enzyme geranylgeranyl diphosphate synthase (GGDPS), reduced protein geranylgeranylation without altering protein farnesylation...

PURPOSE: To review and summarize evidence on the role of diet and lifestyle factors and prostate cancer progression, with a specific focus on habits after diagnosis and the risk of subsequent disease recurrence, progression, or death. METHODS: Given the well-documented heterogeneity of prostate cancer and the long survivorship of the majority of diagnoses, our goal was to summarize and describe modifiable risk factors for clinically relevant prostate cancer. We focused where possible on epidemiologic studies of post-diagnostic habits and prostate cancer progression, defined as recurrence (e...

Metastatic prostate cancer is a lethal disease that remains incurable despite the recent approval of new drugs, thus making the development of alternative treatment approaches urgently needed. A more precise understanding of the molecular mechanisms underlying prostate cancer dissemination could lead to the identification of novel therapeutic targets for the design of efficient anti-metastatic strategies. MicroRNA (miRNAs) are endogenous, small non-coding RNA molecules acting as key regulators of gene expression at post-transcriptional level...

Among the estimated 230,000 men diagnosed with prostate cancer in the US each year there has been a rise in the number of radical prostatectomies (RP). There is some debate over the value of immediate adjuvant therapy following RP in men with high-risk pathological features versus delayed salvage radiation therapy when signs of disease progression are observed. Thus, it would be potentially useful to inform post-RP management strategies by more clearly identifying those patients at higher risk of progression and death from prostate cancer...
