    Androgen
    Receptor Signaling in Macrophages Promotes TREM-1-Mediated Prostate Cancer Cell Line Migration and Invasion

    Researchers showed that androgen receptor signaling in the macrophage-like THP-1 cell line supported prostate cancer cell line migration and invasion in culture via increased Triggering Receptor Expressed on Myeloid cells-1 (TREM-1) signaling and expression of its downstream cytokines.

    An
    Inverted CAV1 (Caveolin 1) Topology Defines Novel Autophagy-Dependent Exosome Secretion from Prostate Cancer Cells

    Investigators showed that CAV1 could be secreted from specific prostate cancer types in an inverted vesicle-associated form consistent with the features of bioactive CAV1 secretion.

    Abstract

    Aberrant
    Activation of Super Enhancer and Choline Metabolism Drive Antiandrogen Therapy Resistance in Prostate Cancer

    Scientists identified a group of super enhancers that were abnormally activated in Enz-resistant castration-resistant prostate cancer cells and associated with enhanced transcription of a subset of tumor promoting genes such as CHPT1.

    Abstract

    EGFR as a Stable Marker of Prostate Cancer Dissemination to Bones

    EGFR status was compared to clinical parameters and multiple molecular factors were assessed using immunohistochemistry and gene ontology analysis. The functional aspect of EGFR was evaluated by plating PC-3 cells on soft and rigid matrices.

    Cancer-Derived MMP-3 Controls Intrinsic Cell Growth and Extrinsic Angiogenesis

    Matrix metalloproteinase (MMP)-3 ablation in prostate cancer cell lines significantly reduced in vitro growth combined with lowered AKT and ERK phosphorylation and total VEGFR1 and FGFR3 protein levels.

    The
    AKR1C3/AR-V7 Complex Maintains CRPC Tumor Growth by Repressing B4GALT1 Expression

    Researchers observed a positive correlation between AKR1C3 and androgen receptor splice variant 7 (AR-V7) staining in tissues from prostate rebiopsy at metastatic castration‐resistant prostate cancer (mCRPC). Mechanistically, AKR1C3 interacted with AR-V7 protein in CRPC cells, which could reciprocally inhibit AR-V7 and AKR1C3 protein degradation.

    Activation
    of GPR56, a Novel Adhesion GPCR, Is Necessary for Nuclear Androgen Receptor Signaling in Prostate Cells

    Scientists demonstrated that adhesion GPCR 205 could be activated by androgens to stimulate the Rho signaling pathway, a pathway that plays an important role in prostate tumor cell metastasis.

    Zingerone
    Suppresses Cell Proliferation via Inducing Cellular Apoptosis and Inhibition of the PI3K/AKT/mTOR Signaling Pathway in Human Prostate Cancer PC-3 Cells

    Scientists evaluated the efficacy of zingerone at different doses on the prostate cancer cell line regarding apoptosis, upstream signing molecules such as Akt/mTOR, and migration metastasis.

    Cytokines and Chemokines Initiate Multiple Prostate Cancer Biologic Pathways of Cellular Proliferation, Heterogeneity and Metastasis in a Racially Diverse Population and Underlie the Genetic/Biologic Mechanism of Racial Disparity

    The authors unravel the gene network and identified biologic pathways that impacted activation of the androgen receptor, mesenchymal epithelial transition and chemokines associated with metastasis in the prostate cancer tissue from 639 radical prostatectomy specimens.
