    Ral GTPases promote breast cancer metastasis by controlling biogenesis and organ targeting of exosomes

    Shima Ghoroghi, Benjamin Mary ... Vincent Hyenne
    A combination of animal models reveal how the molecular mechanisms of exosome secretion (RalA/B-dependent) are linked to their cargo content and their function in breast cancer pre-metastatic niche formation.

    Evolution of fibroblasts in the lung metastatic microenvironment is driven by stage-specific transcriptional plasticity

    Ophir Shani, Yael Raz ... Neta Erez
    Metastases-associated fibroblasts show stage-dependent transcriptional plasticity and their rewiring is regulated by Myc.

    Dynamic analysis of circulating tumor DNA to predict the prognosis and monitor the treatment response of patients with metastatic triple-negative breast cancer: A prospective study

    Yajing Chi, Mu Su ... Huihui Li
    ctDNA predict prognosis and treatment response of mTNBC patients more sensitively than traditional tumor markers, which implies ctDNA may be valuable for individualized treatment decision-making and paves the way for a non-invasive real-time clinical management strategy in patients with mTNBC.

    Estrogen receptor alpha somatic mutations Y537S and D538G confer breast cancer endocrine resistance by stabilizing the activating function-2 binding conformation

    Sean W Fanning, Christopher G Mayne ... Geoffrey L Greene
    Two common mutant versions of estrogen receptor alpha achieve constitutive activity and hormone-resistance by preferentially adopting a suite of conformations that expose the coregulator-binding surface.

    Dalpiciclib partially abrogates ER signaling activation induced by pyrotinib in HER2+HR+ breast cancer

    Jiawen Bu, Yixiao Zhang ... Caigang Liu
    Dalpiciclib could partially abrogate ER nuclear transportation induced by pyrotinib in HER2+HR+ breast cancer and CALML5 could serve as a potential risk factor in the treatment of HER2+HR+ breast cancer.

    A modelled evaluation of the impact of COVID-19 on breast, bowel, and cervical cancer screening programmes in Australia

    Carolyn Nickson, Megan A Smith ... Karen Canfell
    Modelled estimates for changes in cancer incidence, staging, and demand on health services are presented for a range of potential COVID-related disruptions to national population screening programmes for breast, cervical, and colorectal cancer, indicating markedly different impacts for each programme.

    Single-cell RNA-sequencing reveals distinct patterns of cell state heterogeneity in mouse models of breast cancer

    Syn Kok Yeo, Xiaoting Zhu ... Jun-Lin Guan
    The unraveling of distinct mammary tumor hierarchies in various mouse models of breast cancer emphasizes the need to account for specific cell states with potentially varying therapeutic vulnerabilities in tumors.

    Effects of neoadjuvant stereotactic body radiotherapy plus adebrelimab and chemotherapy for triple-negative breast cancer: A pilot study

    Guanglei Chen, Xi Gu ... Caigang Liu
    Stereotactic body radiotherapy combined with immunotherapy and chemotherapy in neoadjuvant setting exhibited a promising anti-tumor activity and an acceptable safety profile in triple-negative breast cancer patients.

    RUNX1, a transcription factor mutated in breast cancer, controls the fate of ER-positive mammary luminal cells

    Maaike PA van Bragt, Xin Hu ... Zhe Li
    Loss of RUNX1, a key regulator of estrogen receptor-positive luminal breast cells, impairs mammary epithelial differentiation and contributes to luminal breast cancer via genetic interactions with a loss of p53 or RB1.

    Assessing the causal role of epigenetic clocks in the development of multiple cancers: a Mendelian randomization study

    Fernanda Morales Berstein, Daniel L McCartney ... Rebecca C Richmond
    GrimAge acceleration may increase the risk of colorectal cancer.
