    METTL1 Promotes Tumorigenesis through tRNA-Derived Fragment Biogenesis in Prostate Cancer

    Investigators showed that the transfer RNA N7-methylguanosine transferase METTL1 was highly expressed in primary and advanced prostate tumors.

    Gain-of-Function Mutant p53 Together with ERG Proto-Oncogene Drive Prostate Cancer by Beta-Catenin Activation and Pyrimidine Synthesis

    Researchers demonstrated that TMPRSS2-ERG fusion and TP53 mutation/deletion co-occur in prostate cancer patient specimens and this co-occurrence accelerates prostatic oncogenesis.

    Androgen Receptor Variants Confer Castration Resistance in Prostate Cancer by Counteracting Antiandrogen-Induced Ferroptosis

    Scientists demonstrated that acute treatment with the antiandrogen enzalutamide decreased glutathione production, increased lipid peroxidation, and induced ferroptosis in prostate cancer cells.

    Abstract

    A GATA2-CDC6 Axis Modulates Androgen Receptor Blockade-Induced Senescence in Prostate Cancer

    Assessment of the invasive potential of cells and senescence status following enzalutamide treatment and/or RNAi-mediated silencing of selected targets was performed in all cell lines, complemented by bioinformatics analyses on a wide range of in vitro and in vivo datasets.

    SQLE Promotes Pancreatic Cancer Growth by Attenuating ER Stress and Activating Lipid Rafts-Regulated Src/PI3K/Akt Signaling Pathway

    Scientists found that squalene epoxidase (SQLE) was a crucial mediator of cholesterol metabolism in prostate cancer growth. They observed a profound upregulation of SQLE in prostate cancer tissues, and its high expression was correlated with poor patient outcomes.

    Inhibition of CDC20 Potentiates Anti-Tumor Immunity through Facilitating GSDME-Mediated Pyroptosis in Prostate Cancer

    Researchers highlighted novel molecular pathways for targeting cellular pyroptosis and enhancing the effectiveness of anti-PD1-based immunotherapy. Prostate cancer cell lines were evaluated via the next-generation RNA sequencing to assess transcriptomic profile upon CDC20 depletion.

    Induction of More Aggressive Tumoral Phenotypes in LNCaP and PC3 Cells by Serum Exosomes from Prostate Cancer Patients

    Scientists studied the effect of exosomes isolated from the serum of patients with prostate cancer (PCa) on various cellular processes associated with increased tumor aggressiveness in two PCa cell lines: LNCaP-FGC and PC3.

    CDC20 Promotes Radioresistance of Prostate Cancer by Activating Twist1 Expression

    Investigators demonstrated that the expression of CDC20 was increased in prostate cancer (PCa) cells by irradiation, and knockdown of CDC20 resulted in inhibition of cell proliferation, migration, tumor formation, induced cell apoptosis, and increased radiosensitivity in PCa in vitro and in vivo.

    Abstract

    RNA-Sequencing Analysis Indicates that N-cadherin Promotes Prostate Cancer Progression by the Epigenetic Modification of Key Genes

    Researchers overexpressed N-cadherin in LNCaP cells and downregulated N-cadherin in PC3 cells by lentiviral transduction. Then, differentially expressed genes and dysregulated biological functions were investigated through RNA sequencing analyses.

    Deregulated Kinase Action in Prostate Cancer: Molecular Basis and Therapeutic Implications.

    The authors provide an overview of kinases that are impacted by gene amplification, gene deletion, or somatic mutations during the progression from localized treatment-naïve prostate cancer (CaP) to metastatic castration-resistant CaP or neuroendocrine CaP.

    Abstract
    INDUSTRY AND POLICY NEWS

    Dr. Tanya Stoyanova Awarded $1.5 Million to Uncover New Ways to Treat Advanced Prostate Cancer

    Dr. Tanya Stoyanova was awarded a $1.5 million grant from the National Cancer Institute to identify new treatment strategies for neuroendocrine prostate cancer. The grant will help support Stoyanova and her team identify new molecular mechanisms underlying the development of neuroendocrine prostate cancer.
