What does ALK stand for?

1. Anaplastic Lymphoma Kinase (ALK)


Anaplastic Lymphoma Kinase (ALK) is a gene that encodes a protein involved in cell growth and development. Mutations in the ALK gene can lead to the development of various types of cancer, including non-small cell lung cancer (NSCLC) and anaplastic large cell lymphoma (ALCL).

Function and Role in Cancer

ALK is a receptor tyrosine kinase, a type of enzyme that transfers phosphate groups to specific proteins, activating signaling pathways that control cell division and growth. When ALK is mutated or rearranged, it can lead to uncontrolled cell growth and cancer.

Impact and Treatment

Understanding the role of ALK in cancer has led to the development of targeted therapies, such as ALK inhibitors, which block the activity of the mutated ALK protein and help manage certain cancers more effectively. These treatments have shown significant success in patients with ALK-positive cancers.
