As we dig deeper into the expression pattern of STK3, it was observed that while STK3 amplification was noted in a limited group of patients, the overexpression of STK3 is more commonly observed in GC patients: In the TCGA cohort, upregulated STK3 levels were identified in 76 GC patients (19.8%), whereas only 24 patients (6.3%) exhibited STK3 gene amplification. Here, STK3 is linked to gastric cancer.
