Targeted Metabolomics Analyses Reveal Specific Metabolic Alterations in High-Grade Prostate Cancer Patients

2020

Prostate cancer (PCa) is a hormone-dependent tumor characterized by an extremely heterogeneous prognosis. Despite recent advances in partially uncovering some of the biological processes involved in its progression, there is still an urgent need for identifying more accurate and specific prognostic procedures to differentiate between disease stages. In this context, targeted approaches, focused on mapping dysregulated metabolic pathways, could play a critical role in identifying the mechanisms driving tumorigenesis and metastasis. In this study, a targeted analysis of the nuclear magnetic resonance-based metabolomic profile of PCa patients with different tumor grades, guided by transcriptom…

Aggressive variants of prostate cancer – Are we ready to apply specific treatment right now?

2019

Recently, adoption of novel drugs for systemic treatment of metastatic prostate cancer has led to a striking improvement of response rate and survival in both hormone-sensitive and castration-resistant disease. In most cases, prostate cancer essentially depends on androgen receptor signaling axis, even in castration-resistant setting, and hence may be targeted by second generation hormonal therapy. However, a subset of patients bears androgen-independent cancer biology with a short-term response to hormonal treatment, early and extensive visceral metastases, low PSA levels and poor outcomes. Identification and specific management of these rapidly fatal malignancies is of an unmet medical ne…

Involvement of Bax and Bcl-2 in induction of apoptosis by essential oils of three Lebanese Salvia species in human prostate cancer cells

2018

Prostate cancer is one of the most common forms of cancer in men, and research to find more effective and less toxic drugs has become necessary. In the frame of our ongoing program on traditionally used Salvia species from the Mediterranean Area, here we report the biological activities of Salvia aurea, S. judaica and S. viscosa essential oils against human prostate cancer cells (DU-145). The cell viability was measured by 3(4,5-dimethyl-thiazol-2-yl)2,5-diphenyl-tetrazolium bromide (MTT) test and lactate dehydrogenase (LDH) release was used to quantify necrosis cell death. Genomic DNA, caspase-3 activity, expression of cleaved caspase-9, B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X (Ba…

Roles of p53, NF-κB and the androgen receptor in controlling NGAL expression in prostate cancer cell lines

2018

Neutrophil gelatinase-associated lipocalin (NGAL a.k.a lipocalin 2, lnc2) is a secreted protein which can form a complex with matrix metalloproteinase-9 (MMP9). This MMP9/NGAL complex has been associated with metastasis. MMP9 and NGAL are detected in the urine of patients afflicted with many different types of cancer, including prostate cancer. The effects of p53, NF-κB and the androgen receptor (AR) on the expression of NGAL was examined in four prostate cancer cell lines. Prostate cancer cell lines that are AR negative and expressed either mutant or no p53 (DU145 and PC3) displayed higher levels of NGAL expression compared to the prostate cancer cell lines (LNCaP and 22Rv-1) which are AR …

The Clip Approach : A Visual Methodology to Support the (Re)Construction of Life Narratives

2021

Major life changes may cause an autobiographical rupture and a need to work on one’s narrative identity. This article introduces a new qualitative interview methodology originally developed to facilitate 10 prostate cancer patients and five spouses in the (re)creation of their life narratives in the context of a series of interventive interviews conducted over a timespan of several months. In “The Clip Approach” the interviewees’ words, phrases, and metaphors are reflected back in a physical form (“the Clips”) as visual artifacts that allow the interviewees to re-enter and re-consider their experience and life and re-construct their narratives concerning them. Honoring the interviewees as …

2022

Abstract Purpose To investigate the effects of different antibiotic prophylaxis regimens in patients with diabetes mellitus (DM) candidates to trans-rectal ultrasound-guided prostate biopsy (TRUSPB). Methods 143 outpatients with DM who underwent TRUSPB during the period 2018–2020 were selected from a cohort of 1150 patients in 3 different institutions. Exclusion criteria were allergies, concomitant anti-platelet therapies and uncontrolled DM. Different antibiotic prophylaxis regimens were adopted. Bacterial resistance levels to fluoroquinolones into the different communities were also collected. Univariable and multivariable binomial logistic regression analyses were used to assess the odds…

Radiomics and artificial intelligence in prostate cancer: new tools for molecular hybrid imaging and theragnostics

2022

AbstractIn prostate cancer (PCa), the use of new radiopharmaceuticals has improved the accuracy of diagnosis and staging, refined surveillance strategies, and introduced specific and personalized radioreceptor therapies. Nuclear medicine, therefore, holds great promise for improving the quality of life of PCa patients, through managing and processing a vast amount of molecular imaging data and beyond, using a multi-omics approach and improving patients’ risk-stratification for tailored medicine. Artificial intelligence (AI) and radiomics may allow clinicians to improve the overall efficiency and accuracy of using these “big data” in both the diagnostic and theragnostic field: from technical…

Metronomic cyclophosphamide induces regulatory T cells depletion and PSA‐specific T cells reactivation in patients with biochemical recurrent prostat…

2019

Biochemical recurrence (BCR) occurs in up to 40% of prostate cancer patients after prostatectomy. In our study, we performed an immune monitoring study in 20 prostate cancer patients with BCR previously treated with metronomic cyclophosphamide (mCTX). We observed a decrease of regulatory T cells (Tregs) from 2 months and this was more pronounced after 6 months of mCTX treatment. This drop of Tregs was associated with increased level of activated HLADR+ CD45R0+ T cells in peripheral blood. Furthermore, a reactivation of Th1 polarized anti-PSA T-cell response was detected in BCR patients treated with mCTX. However, dendritic cell subsets counts and activation were not influenced by the treatm…
