    Long-Term Multimodal Recording Reveals Epigenetic Adaptation Routes in Dormant Breast Cancer Cells

    The authors investigated genetic and transcriptional changes underlying tumor awakening, and it was demonstrated that endocrine therapies induced nongenetic cell state transitions into dormancy in a stochastic subset of cells via epigenetic reprogramming.

    Ropivacaine as a Novel AKT1 Specific Inhibitor Regulates the Stemness of Breast Cancer

    The effects of ropivacaine on breast cancer stemness were investigated by in vitro and in vivo assays. Scientists reported that ropivacaine suppressed stem cell-like properties of breast cancer cells.

    Endocytic Activation and Exosomal Secretion of Matriptase Stimulate the Second Wave of EGF Signaling to Promote Skin and Breast Cancer Invasion

    Investigators demonstrated a vesicular-trafficking-mediated interplay between matriptase and epidermal growth factor (EGF) signaling in skin and breast cancer promotion. EGF induced matriptase to undergo endocytosis together with the EGF receptor, followed by acid-induced activation in endosomes.

    IQGAP1 and NWASP Promote Human Cancer Cell Dissemination and Metastasis by Regulating β1-Integrin via FAK and MRTF/SRF

    Scientists observed that β1-integrin was required for human prostate and breast cancer cell adhesion to endothelial cells (EC) under shear-stress conditions in vitro and to lung blood vessel ECs in vivo.

    Establishment of Patient-Derived Organoids for Guiding Personalized Therapies in Breast Cancer Patients

    The authors established 75 patient-derived breast cancer organoid models. The results of H&E staining, immunohistochemical, and whole-exome sequencing revealed that patient-derived organoids inherited the histologic and genetic characteristics of their parental tumor tissues.

    Overcoming Radioresistance of Breast Cancer Cells With MAP4K4 Inhibitors

    Researchers explored the biological function of mitogen-activated protein kinase kinase kinase kinase 4 (MAP4K4) in radioresistant breast cancer cells using two MAP4K4 inhibitors.

    Methyl-CpG Binding Domain Protein 2 (Mbd2) Drives Breast Cancer Progression through the Modulation of Epithelial-to-Mesenchymal Transition

    To test whether Mbd2 played a causal role in mammary tumor growth and metastasis, the authors performed genetic knockout (KO) of Mbd2 in transgenic mice and compared mammary tumor progression kinetics between the wild-type and KO groups.

    Progression From Ductal Carcinoma In Situ to Invasive Breast Cancer: Molecular Features and Clinical Significance

    The authors review the key signaling pathways in breast cancer that may contribute to ductal carcinoma in situ (DCIS) initiation and progression. They also explore the molecular features of DCIS and invasive ductal carcinoma.
