In Vitro Studies to Define the Cell-Surface and Intracellular Targets of Polyarginine-Conjugated Sodium Borocaptate as a Potential Delivery Agent for Boron Neutron Capture Therapy

Scientists performed BSH-polyR-based boron neutron capture therapy (BNCT) against glioma stem-like cells and revealed that BSH-polyR successfully induced BNCT-dependent cell death specifically in CD44High cells.

Upregulation of S100A10 in Metastasized Breast Cancer Stem Cells

Knockdown of S100A10 in breast cancer cells suppressed and overexpression of S100A10 in breast cancer patient‐derived tumor xenograft cells enhanced their invasion abilities and 3D organoid formation capacities in vitro.

The Role of Smoothened in Cancer

Smoothened (SMO) expression correlates with tumor size, invasiveness, metastasis and recurrence. In addition, SMO inhibitors can suppress cancer formation, reduce the proliferation of cancer cells, trigger apoptosis and suppress cancer stem cell activity.

The Role of Breast Cancer Stem Cell-Related Biomarkers as Prognostic Factors

The cell-surface and subcellular biomarkers related to breast cancer stem cell (BCSC) phenotypes are increasingly being recognised. These biomarkers are useful for the isolation of BCSCs and can serve as potential therapeutic targets and prognostic tools to monitor treatment responses.
