Nuclear Transcription Factor-kappaB in Hodgkin's Disease

Abstract

Nuclear factor-kappaB (NF- κ B) is a transcriptional factor that was originally discovered in the nucleus of B cells that bind to the kappa light chain of the immunoglobulins. Research during 15 years, however, has revealed that NF- κ B is present in its inactive state in the cytoplasm of almost every cell type. When activated, NF- κ B translocates to the nucleus, binds the DNA and regulates the expression of over 200 different genes. The product of these genes regulate the immune system, cell proliferation, tumor metastasis, inflammation and viral replication. Several tumor cell types express constitutively activated form of NF- κ B and it is required for the proliferation of the tumor cells. Numerous studies have shown that Hodgkin's disease cells exhibit constitutive active NF- κ B. The present review examines the mechanism how NF- κ B is activated and its relevance to Hodgkin's disease.
