    Biobank of genetically defined murine prostate cancer tumoroids uncovers oncogenic pathways and drug vulnerabilities driven by PTEN-loss. (PubMed, Cell Rep Methods)
    Notably, these compounds also inhibited the growth of several human PCa cell lines and displayed synergistic effects when combined with the standard-of-care antiandrogen enzalutamide. Together, our findings provide evidence that murine tumoroids are versatile preclinical models for studying PCa tumorigenesis and drug sensitivities to develop therapeutic options for PCa patients.

    Deficiency of PTEN Confers Hypersensitivity to Fatty Acid-Mediated ER Stress in Transformed Hepatocytes. (PubMed, Int J Mol Sci)
    Xenograft studies showed that PTEN KO HCC tumors progressed faster than did the control tumors when mice were fed with normal chow and slower under a high-fat diet. We suggest that while the health risks of a fatty acid-rich diet to liver function and the increased propensity to develop HCC are prominent, once a PTEN-deficient HCC has been established, it exposes vulnerability to lipid overload that can be exploited through diet and pharmacological interventions.

    PTEN loss appears to represent an early molecular alteration associated with adverse pathological features. Longer follow-up is needed to determine the predictive value of these biomarkers for recurrence and long-term outcomes.

    From prostate specific antigen to genomic signatures: Advances in biomarkers for prostate cancer diagnosis and prognosis. (PubMed, Transl Oncol)
    Additionally, the review addresses key genetic alterations implicated in prostate carcinogenesis, including mutations in BRCA1/2, HOXB13, and PTEN deletions, as well as changes in the androgen receptor pathway. By evaluating recent advancements and applications of these biomarkers, this review aims to enhance understanding of their role in improving early diagnosis, prognosis, and personalised management of prostate cancer.

    DNA copy number patterns reveal prognostic markers and elucidate mechanisms of evolution in IDH-mutant astrocytoma. (PubMed, Neuro Oncol)
    Patients with hemizygous loss of CDKN2A/B, loss of PTEN, increased number of copy number alterations, specific chromosomal arm losses or rs55705857 germline risk allele have reduced overall survival.

    PTEN Deletions Are Associated With Tumor Progression But Unrelated to Patient Prognosis in Muscle-Invasive Urothelial Bladder Carcinomas: A Large Multi-Center Validation Study on 2710 Urothelial Bladder Carcinomas. (PubMed, Genes Chromosomes Cancer)
    It is concluded that PTEN deletions accumulate with grade progression in non-invasive urothelial carcinomas of the urinary bladder. The absence of a prognostic role of PTEN deletions in pT2-4 urothelial carcinomas is in line with our notorious inability to predict the clinical course of these tumors by only one morphological or molecular feature.

    EPI-SauriCas9-based mouse ovarian cancer models recapitulating pten deletion in patients. (PubMed, Commun Biol)
    High-throughput drug screening identifies FK228 and thioguanine as promising therapeutic candidates, both of which show in vivo efficacy and are validated in PTEN-deleted organoids. Together, these results establish MEPP as a platform for studying PTEN-deleted ovarian cancer and provide a strategy for generating clinically relevant tumor models through targeted gene editing.
