    PRC2-Mediated Epigenetic Suppression of Type I IFN-STAT2 Signaling Impairs Antitumor Immunity in Luminal Breast Cancer

    Researchers demonstrated that inhibition of cancer-intrinsic EZH2 promoted antitumor immunity in estrogen receptor a-positive breast cancer.

    Bip-Yorkie Interaction Determines Oncogenic and Tumor-Suppressive Roles of Ire1/Xbp1s Activation

    In human TNBC cell lines and xenograft models, ectopic XBP1s or HSPA5 expression alleviated tumor growth but aggravated cell migration and invasion. These findings uncovered a conserved crosstalk between the Ire1/Xbp1s and Hippo signaling pathways under physiological settings.

    Abstract

    Aberrant Phosphorylation Inactivates Numb in Breast Cancer Causing Expansion of the Stem Cell Pool

    Researchers showed that asymmetric Numb partitioning per se was insufficient for the proper control of mammary stem cell dynamics, with differential phosphorylation and functional inactivation of Numb in the two progeny also required.

    Abstract

    A MYC-ZNF148-ID1/3 Regulatory Axis Modulating Cancer Stem Cell Traits in Aggressive Breast Cancer

    Scientists identified the zinc finger transcription factor 148 (ZNF148) as a direct target of the MYC proto-oncogene (MYC). ZNF148 suppressed cell proliferation and migration and was transcriptionally repressed by MYC in breast cancer.

    Tinengotinib (TT-00420), a Novel Spectrum-Selective Small Molecule Kinase Inhibitor, Is Highly Active Against Triple Negative Breast Cancer

    Exposure to tinengotinib specifically inhibited proliferation across all subtypes of TNBC in vitro and in vivo, while leaving luminal breast cancer cells intact. Incubation of HCC1806 with tinengotinib led to dose-dependent down-regulation of genes essential for TNBC cell growth and proliferation.

    NSMCE2, a Novel Super-Enhancer-Regulated Gene, Is Linked to Poor Prognosis and Therapy Resistance in Breast Cancer

    Researchers bioinformatically identified two novel super-enhancer-associated genes – NSMCE2 and MAL2. Through in-vitro pharmacological super-enhancer disruption assays, they confirmed that super-enhancers upregulated NSMCE2 and MAL2 transcriptionally.

    Targeting Hypoxia-Inducible Factor-1alpha: A New Strategy for Triple-Negative Breast Cancer Therapy

    The potential significance of targeting HIF-1α for immunotherapy, chemotherapy, anti-angiogenic therapy, and photodynamic therapy is discussed. The intrinsic mechanism, existing problems and future directions of targeting HIF-1α are also studied.

    UC Researcher Receives Grant to Develop New Breast Cancer Treatment

    A University of Cincinnati Venture Lab-backed startup has begun developing breast cancer treatment that may be more effective with fewer side effects, thanks to RNA nanotechnology that is similar to what was used to produce COVID-19 vaccines.
