This targeted drug delivery approach supports for the first time the clinical relevance of inducing GSDMD-dependent pyroptosis, a cell death mechanism alternative to apoptosis, in CRC models, leading to the selective elimination of CXCR4+ cancer stem cells, which are associated with resistance, metastases and anti-apoptotic upregulation. The gene discussed is CXCR4; the disease is colorectal carcinoma.
