Statin use and oncological outcomes in a propensity-matched cohort of nonmetastatic castration resistant prostate cancer patients of the ARAMIS trial.

Introduction: While observational studies suggest favorable associations between statin use and prostate cancer (CaP) outcomes, data from randomized-controlled trials remain inconclusive. Our study explores the relationship between statin use and survival outcomes in the context of the phase III ARAMIS study, a trial of darolutamide in the treatment of nonmetastatic castration-resistant prostate cancer.

Methods: We reviewed all 1,509 patients in the ARAMIS trial.

Statin Concentration in Prostatic Tissue is Subtype- and Dose-dependent.

Objective: To evaluate for the first time, comparative serum and prostate tissue concentrations of lipophilic and hydrophilic statins.

Methods: After reviewing all patients who underwent radical prostatectomy between 1993 and 2019, we selected 80 patients taking atorvastatin (lipophilic) or rosuvastatin (hydrophilic) for cholesterol control and with available banked fresh-frozen tissue from the prostatectomy. Primary endpoint was serum and prostate statin concentration measured by HPLC-mass spectrometry analysis.

Recruitment of FBXO22 for targeted degradation of NSD2.

Targeted protein degradation (TPD) is an emerging therapeutic strategy that would benefit from new chemical entities with which to recruit a wider variety of ubiquitin E3 ligases to target proteins for proteasomal degradation. Here we describe a TPD strategy involving the recruitment of FBXO22 to induce degradation of the histone methyltransferase and oncogene NSD2. UNC8732 facilitates FBXO22-mediated degradation of NSD2 in acute lymphoblastic leukemia cells harboring the NSD2 gain-of-function mutation p.

Sterol-like drugs potentiate statin-triggered prostate cancer cell death by inhibiting SREBP2 nuclear translocation.

There is an urgent need to provide immediate and effective options for the treatment of prostate cancer (PCa) to prevent progression to lethal castration-resistant PCa (CRPC). The mevalonate (MVA) pathway is dysregulated in PCa, and statin drugs commonly prescribed for hypercholesterolemia, effectively target this pathway. Statins exhibit anti-PCa activity, however the resulting intracellular depletion of cholesterol triggers a feedback loop that restores MVA pathway activity, thus diminishing statin efficacy and contributing to resistance.
