Cannabidiol Suppresses Metastatic Castration-Resistant Prostate Cancer Progression and Recurrence through Modulating Tryptophan Catabolism.

ACS Pharmacol Transl Sci

December 2024

School of Basic Pharmaceutical and Toxicological Sciences, College of Pharmacy, University of Louisiana at Monroe, 1800 Bienville Drive, Monroe, Louisiana 71201, United States.

Metastatic castration-resistant prostate cancer (mCRPC) is an aggressive phenotype of prostate cancer (PC). Tryptophan oxidative catabolism by indoleamine 2,3-dioxygenase-1 (IDO1) cleaves the indole ring to kynurenine (Kyn), an endogenous ligand for the aryl hydrocarbon receptor (AhR), which activates multiple tumorigenesis pathways. The IDO1-Kyn-AhR axis is aberrantly dysregulated in mCRPC.

Department of Drug Discovery and Development, Harrison College of Pharmacy, Pharmacy Research Building, Auburn University, Auburn, Alabama 36849, United States.

Preclinical and clinical studies have indicated that compromised blood-brain barrier (BBB) function contributes to Alzheimer's disease (AD) pathology. BBB breakdown ranged from mild disruption of tight junctions (TJs) with increased BBB permeability to chronic integrity loss, affecting transport across the BBB, reducing brain perfusion, and triggering inflammatory responses. We recently developed a high-throughput screening (HTS) assay to identify hit compounds that enhance the function of a cell-based BBB model.

The purpose of this study was to assess the efficacy, specificity, and predictive value of a newly discovered biomarker, Zinc finger-like1 protein (referred to as neuroendocrine marker, NEM) for the detection of prostate cancer (PCa). We retrospectively analyzed banked plasma samples from 508 men, with a median age of 67 years (range 48-97), to compare the performance of NEM and PSA in predicting subsequent histologic PCa. The cohort consisted of four groups of patients visiting a urology clinic: (1) patients not diagnosed with either benign prostatic disease or prostate cancer (PCa) were defined as normal; (2) patients diagnosed with benign hyperplasia (BPH) but not PCa; (3) patients with confirmed PCa; and (4) patients with cancer other than PCa.
