CASP3 and laryngotracheoesophageal cleft: Against LC cells, we reviewed several reports, where 10–50 nm AgNPs inhibited their proliferation and induced their death by increasing the generation of ROS, upregulating signaling pathways (e.g., mitochondrial pathway), enhancing enzyme activity (e.g., caspase 3 and 9), inducing morphological changes to cellular components (e.g., chromatin condensation), or inhibiting key carcinogenic phenomena.
