    Senescence Reprogramming by TIMP1 Deficiency Promotes Prostate Cancer Metastasis

    The authors identified the metalloproteinase inhibitor TIMP1 as a molecular switch that determines the effects of senescence in prostate cancer. Senescence driven either by PTEN deficiency or chemotherapy limited the progression of prostate cancer in mice.

    Bipotent Progenitors Do Not Require Androgen Receptor for Luminal Specification during Prostate Organogenesis

    Scientists suggested that low androgen levels correlate with luminal plasticity in prostate development and may have implications for understanding how AR inhibition promotes lineage plasticity in prostate cancer.

    DEPTOR Is a Direct p53 Target that Suppresses Cell Growth and Chemosensitivity

    Investigators report that DEP-domain containing mTOR-interacting protein (DEPTOR) is a downstream target of the tumor suppressor, p53, whose activity was positively correlated with DEPTOR expression both in vitro in cell cultures and in vivo in mouse tissues.

    Platelet PD-L1 Suppresses Anti-Cancer Immune Cell Activity in PD-L1 Negative Tumors

    Researchers showed that platelet-derived programmed cell death protein-1 (PD-L1) regulated the growth of PD-L1 negative tumors and that interference with platelet binding to PD-L1 negative cancer cells promoted T cell-induced cancer cytotoxicity.

    8-Epi-Xanthatin Induces the Apoptosis of DU145 Prostate Carcinoma Cells through Signal Transducer and Activator of Transcription 3 Inhibition and Reactive Oxygen Species Generation

    The authors found STAT3 inhibitors from natural sources and found that Xanthium fruit extracts decreased phosphorylation of STAT3‐Y705. 8‐Epi‐xanthatin (EXT) was isolated from the extracts. When DU145 prostate cancer cells were treated with EXT, p‐STAT3‐Y705 was decreased with an IC50 of 3.2μM.

    HPLC Phenolic Profile and Induction of Apoptosis by Linum Usitatissimum Extract in LNCaP Cells by Caspase3 and Bax Pathways

    Researchers reported the phenolic and flavonoid constituents, antioxidant activity, and potential of the L. usitatissimum plant extract against prostate cancer cells. The phenolic and flavonoid compound profile of the extract were established using HPLC analysis.

    Image-Based Phenotyping of Disaggregated Cells Using Deep Learning

    To acquire a training set for deep-learning, scientists imaged eight standard cancer cell lines. These cell lines were derived from colorectal and prostate carcinoma, prostate and mammary adenocarcinoma, osteosarcoma, as well as neutrophilic, monocytic and T-cell leukemia.

    Equivocal, Explicit and Emergent Actions of PKC Isoforms in Cancer

    The maturing mutational landscape of cancer genomes, the development and application of clinical interventions and evolving insights into tumour-associated functions reveal unexpected features of the protein kinase C (PKC) family of serine/threonine protein kinases.

    The Nuclear Export Protein XPO1 — From Biology to Targeted Therapy

    XPO1 is overexpressed in patients with cancer, including in those with pancreatic, gastric, prostate and colorectal cancers, and such overexpression is associated with disease progression, treatment resistance, and inferior overall survival or progression-free survival.

    Abstract

    Patient-Derived Tumor Models for Personalized Therapeutics in Urological Cancers

    Preclinical knowledge of dysregulated pathways and potential biomarkers for urological cancers has undergone limited translation into the clinic. Moreover, the low approval rate of new anticancer drugs and the heterogeneous drug responses in patients indicate that current preclinical models do not always reflect the complexity of malignant disease.
