    FRMD6 Has Tumor Suppressor Functions in Prostate Cancer

    In overexpression and CRISPR/Cas9 knockout experiments in prostate cancer cell lines, FRMD6 inhibited viability, proliferation, cell cycle progression, colony formation, 3D spheroid growth, and tumor xenograft growth in mice.

    Metabolic Reprogramming and Predominance of Solute Carrier Genes during Acquired Enzalutamide Resistance in Prostate Cancer

    The transcriptomic profile of paired enzalutamide-sensitive and resistant LNCaP and C4-2B prostate cancer cells were compared for identification of genes involved in drug resistance by performing an unbiased bioinformatics analysis and further validation. Next-Gen sequencing detected 9409 and 7757 genes differentially expressed in LNCaP and C4-2B cells, compared to their parental counterparts.

    Omega-3 Eicosapentaenoic Acid Reduces Prostate Tumor Vascularity

    Testing autocrine and paracrine effects in an avascular tumor spheroid growth assay, both exogenous monoacylglyceride-conjugated form of eicosapentaenoic acid and endogenous ω3 reduced VEGF secretion and in vitro endothelial cell tube formation and blocked tumor spheroid growth, suggesting that ω3 molecules could directly hinder prostate cancer cell growth.

    Efficacy and Mechanism of Action of Marine Alkaloid 3,10-Dibromofascaplysin in Drug-Resistant Prostate Cancer Cells

    Efficacy and mechanism of action of marine alkaloid 3,10-dibromofascaplysin were investigated in human prostate cancer cells harboring different levels of drug resistance. Anticancer activity was observed across all cell lines examined without signs of cross-resistance to androgen receptor targeting agents or taxane based chemotherapy.

    Non-Epigenetic Induction of HEXIM1 by DNMT1 Inhibitors and Functional Relevance

    5-Aza-2′deoxycytidine (5-AzadC) induced hexamethylene bisacetamide induced protein 1 (HEXIM1) expression in prostate cancer cell lines and triple negative breast cancers. 5-AzadC-induced DNA damage enhanced P-TEFb occupancy via a mechanism that involved activation of ATR and ATM and induction of NF-ĸB recruitment to the HEXIM1 promoter.

    Intra-Individual Dynamic Comparison of 18F-PSMA-11 and 68Ga-PSMA-11 in LNCaP Xenograft Bearing Mice

    Saturation binding experiments were conducted by incubation of LNCaP cells with 18F-PSMA-11 or 68Ga-PSMA-11 for one hour, followed by determination of the specific and aspecific binding.

    Pseudomonas Exotoxin A Based Toxins Targeting Epidermal Growth Factor Receptor for the Treatment of Prostate Cancer

    Scientists tested the targeted toxins epidermal growth factor (EGF)-PE40 and EGF-PE24mut consisting of the natural ligand EGF as binding domain and PE40, the natural toxin domain of Pseudomonas Exotoxin A, or PE24mut, the de-immunized variant thereof, as toxin domains.

    Hepsin Promotes Epithelial-Mesenchymal Transition and Cell Invasion through the miR-222/PPP2R2A/AKT Axis in Prostate Cancer

    Hepsin expression was upregulated in prostate cancer tissue samples and cell lines. Inhibition of hepsin attenuated EMT and cell invasion and downregulated the expression of miR-222. Decreased miR-222 expression enhanced the level of PPP2R2A, which in turn attenuated the AKT signaling.

    Current Experimental Human Tissue‐Derived Models for Prostate Cancer Research

    The use of human prostate cancer tissues in experiments has enabled the collection and verification of clinically relevant data, including chemical reactions, changes in proteins, and specific gene expression. Tissue recombination models have been employed for studying prostate development, the initiation and progression of prostate cancer, and the tumor microenvironment.
