Low LCOR allows cancer stem cells hide out
Triple-negative breast cancer (TNBC) is notoriously difficult to treat, and while anti-PD-1 and anti-PD-L1 immunotherapies are approved as treatment options, they are not particularly effective in this setting. Investigating immunotherapy resistance in TNBC, Pérez-Núñez et al. recently uncovered a novel tumor escape mechanism involving LCORlow cancer stem cells (CSCs) – and came up with a potential strategy to overcome it. Their results were recently published in Nature Cancer.
