A family of enzymes that play a crucial role in the signaling pathways of various cytokines and growth factors. They are involved in the regulation of immune responses, hematopoiesis, and cell proliferation. Dysregulation of JAK signaling has been implicated in several types of cancer, particularly hematological malignancies such as leukemia and lymphoma.
Targeting JAKs with specific inhibitors has emerged as a therapeutic strategy in oncology. JAK inhibitors, such as ruxolitinib and tofacitinib, are used to treat certain blood cancers and autoimmune diseases. These drugs work by blocking the activity of JAKs, thereby inhibiting the signaling pathways that promote cancer cell proliferation and survival.
