JAK2 and diffuse large B-cell lymphoma: Flow cytometry results showed that JAK2 knockdown decreased the apoptosis rate induced by DCZ0858, while more apoptotic cells were found in a group of cells with combined DCZ0858 and JAK2 overexpression, suggesting that JAK2 was involved in DCZ0858-induced apoptosis of DLBCL cells (Fig. 5d).
