[Science Advances] Investigators isolated multiple distinct single-cell clones from the SUM149PT human breast cell line spanning the epithelial-to-mesenchymal transition spectrum having diverse migratory, tumor-initiating, and metastatic qualities, including three unique intermediates.
[Science Translational Medicine] The authors demonstrated that spontaneous triple-negative breast cancer tumors from a genetically engineered mouse model, multiple patient-derived xenografts, and archival patient samples exhibited large populations in vivo of hybrid E/M cells that lead invasion ex vivo while expressing both epithelial and mesenchymal characteristics.
[Annals of Biomedical Engineering] Scientists present an image processing and segmentation pipeline for the detection of 3D GFP-fluorescent triple-negative breast cancer cell nuclei, and they performed quantitative analysis of the formed spatial patterns and their temporal evolution.
[Endocrine-Related Cancer] Investigators compile the current knowledge demonstrating the altered expression of splicing variants and spliceosomal components in BCa, showing the existence of a growing body of evidence supporting the close implication of the alteration in the splicing process in mammary tumorigenesis.
[PLoS One] Scientists examined the effect of glucose as well as its deprivation, and antagonism using the non-metabolized analogue 2-deoxy glucose, on the proliferation of several breast cancer cell lines MCF7, MDA-MB-231, YS1.2 and pII and one normal breast cell line, using the MTT assay.
[Cell Stem Cell] Researchers showed that lysosomes in aged HSCs are hyperacidic, depleted, damaged, and aberrantly activated. Single-cell transcriptomics and functional analyses reveal that suppression of hyperactivated lysosomes using a vacuolar ATPase inhibitor restores lysosomal integrity and metabolic and epigenetic homeostasis in old HSCs.
[Science Translational Medicine] Scientists used highly processive adenine base editor variants to precisely correct some of the most prevalent and severe β-thalassemia–causing mutations in the β-globin–encoding HBB gene, including CD39 and IVS2-1, using NRCH-ABE8e and SpRY-ABE8e, respectively.
[Science Translational Medicine] Investigators reported on a tumor-suppressive mechanism that can be harnessed to simultaneously clear leukemic stem or progenitor cells and promote healthy hematopoiesis.
