Histone deacetylase (HDAC) inhibitors are considered novel agents for cancer chemotherapy. We previously investigated MHY219, a new HDAC inhibitor, and its potent anticancer activity in human prostate cancer cells. In the present study, we evaluated MHY219 molecular mechanisms involved in the regulation of prostate cancer cell migration. Similar to suberanilohydroxamic acid (SAHA), MHY219 inhibited HDAC1 enzyme activity in a dose-dependent manner. MHY219 cytotoxicity was higher in LNCaP (IC50=0.67 μM) than in DU145 cells (IC50=1.10 μM) and PC3 cells (IC50=5.60 μM) after 48 h of treatment. MHY219 significantly inhibited the HDAC1 protein levels in LNCaP and DU145 cells at high concentrations. However, inhibitory effects of MHY219 on HDAC proteins levels varied based on the cell type. MHY219 significantly inhibited LNCaP and DU145 cells migration by down-regulation of matrix metalloprotease-1 (MMP-1) and MMP-2 and induction of tissue inhibitor of metalloproteinases-1 (TIMP-1). These results suggest that MHY219 may potentially be used as an anticancer agent to block cancer cell migration through the repression of MMP-1 and MMP-2, which is related to the reduction of HDAC1.

Importance: Black individuals have a twofold higher rate of prostate cancer death in the US compared with the average population with prostate cancer. Few guidelines support race-conscious screening practices among at-risk Black individuals.
Objective: To examine structural factors that facilitate or impede access to prostate cancer screening among Black individuals in the US.

Cancer vaccines represent a transformative shift in oncology, aiming to prevent malignancies or treat established cancers by training the immune system to recognize tumor-specific or tumor-associated antigens. This review explores the diverse platforms and mechanisms supporting cancer vaccines, ranging from prophylactic vaccines such as HPV and hepatitis B vaccines that have significantly reduced virus-related cancers to therapeutic vaccines like Sipuleucel-T and T-VEC that extend survival in prostate cancer and melanoma. Vaccine types are classified, and delivery platforms including mRNA, peptide, dendritic cell and viral vector-based approaches are examined alongside pivotal clinical trial outcomes.

Age is a major risk factor for a range of diseases including prostate cancer. Understanding how age influences the susceptibility of normal prostate epithelial cells to cancer initiation is complicated by the fact that aging affects all tissues in the body. Assessing how various aging mechanisms influence the prostate epithelium is a necessary step to determine the critical factors associated with aging that increase prostate cancer risk.

Dysfunction of several WD40 family proteins causes diverse endocrine diseases. Until recently, MEP50, a WD40 protein, was considered a Gene of Unknown Significance (GUS) because no inherited diseases had been linked to its function. However, genetic inactivation of MEP50 in mouse models or somatic mutations in humans drive oncogenesis in several endocrine-related cancers, including those of the prostate, breast, and uterus.

Background: Prostatic diseases, consisting of prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer (PCa), pose significant health challenges. While single-omics studies have provided valuable insights into the role of mitochondrial dysfunction in prostatic diseases, integrating multi-omics approaches is essential for uncovering disease mechanisms and identifying therapeutic targets.
Methods: A genome-wide meta-analysis was conducted for prostatic diseases using the genome-wide association studies (GWAS) data from FinnGen and UK Biobank.
