Single‐Cell Transcriptomic Identification of Drug‐Tolerant Persister Mechanisms in Capecitabine‐Treated Triple‐Negative Breast Cancer
Triple‐negative breast cancer (TNBC) is an aggressive subtype defined by the absence of estrogen receptor (ER), progesterone receptor (PR), and HER2 expression. This lack of receptors limits targeted therapies and contributes to high rates of recurrence. A subset of tumor cells survives even intensive chemotherapy,...
