    O-GlcNAcylation of MORC2 at Threonine 556 by OGT Couples TGF-β Signaling to Breast Cancer Progression

    Researchers uncovered a previously unrecognized mechanistic role for MORC family CW-type zinc finger 2 (MORC2) O-GlcNAcylation in breast cancer progression and provided evidence for targeting MORC2-dependent breast cancer through blocking its O-GlcNAcylation.

    Suppression of Breast Cancer-Associated Bone Loss with Osteoblast Proteomes via Hsp90ab1/Moesin-Mediated Inhibition of TGFβ/FN1/CD44 Signaling

    Wnt signaling was activated by the overexpression of Lrp5 and β-catenin in osteoblasts as well as a pharmacological agent and the therapeutic effects of their conditioned medium were evaluated using in vitro cell cultures, ex vivo breast cancer tissues, and a mouse model of osteolysis.

    PBX3-Activated DLG1-AS1 Can Promote the Proliferation, Invasion and Migration of TNBC Cells by Sponging miR-16-5p

    Scientists found that PBX3-activated DLG1-AS1 could promote the proliferation, invasion and migration of TNBC cells by sponging miR-16-5p and elevating JARID2 expression.

    Comprehensive Analysis of FKBP4/NR3C1/TMEM173 Signaling Pathway in Triple-Negative Breast Cancer Cell and Dendritic Cell among Tumor Microenvironment

    The authors identified that FKBP4/NR3C1 axis was a novel negative regulator of TMEM173 in human breast cancer (BC) cells and demonstrated that FKBP4/NR3C1/TMEM173 signaling pathway could regulate autophagy and proliferation of BC cells as well as dendritic cell abundance through exosome release.

    Circular RNA circCCDC85A Inhibits Breast Cancer Progression via Acting as a miR-550a-5p Sponge to Enhance MOB1A Expression

    Researchers explored whether circCCDC85A could function as a miR-550a-5p sponge and influence breast cancer progression and found novel evidence that circCCDC85A inhibited the progression of breast cancer by functioning as a molecular sponge of miR-550a-5p to enhance MOB1A expression.

    Deglycosylated EpCAM Regulates Proliferation by Enhancing Autophagy of Breast Cancer Cells via PI3K/Akt/mTOR Pathway

    Breast cancer cells were transfected with N-glycosylation mutation EpCAM plasmid to express deglycosylated EpCAM. Investigators showed that deglycosylated EpCAM promoted autophagy in breast cancer cells.

    The Involvement of Oncobiosis and Bacterial Metabolite Signaling in Metastasis Formation in Breast Cancer

    Oncobiosis in breast cancer supports invasion, metastasis, and recurrence by supporting cellular movement, epithelial-to-mesenchymal transition, cancer stem cell function, and diapedesis. The microbiome provides novel leverage on breast cancer that should be exploited for better management.
