Abstract

The NF-kappaB/Rel/IkappaB family of transcription factors regulates a number of genes involved in a wide variety of biological processes. The activation of p53, c-myc and Ras genes suggests a role for NF-kappaB in cell proliferation; NF-kappaB is also important in immune and inflammatory responses. By virtue of its role in apoptosis, NF-kappaB participates in the thymus as well as in embryonic development. The NF-kappaB family of transcription factors is also involved in viral transcription, transformation and in the development of some types of human cancers. Given the pivotal role of NF-kappaB, clarification is needed of the mechanisms through which its deregulation contributes to disease. Several aspects of NF-kappaB regulation, such as phosphatase involvement, the mechanism of IkappaB ubiquitination and the regulation of nuclear translocation, remain obscure. Here, we review and discuss the function of NF-kappaB activation in IL-2-stimulation and in apoptosis induced by IL-2 deprivation in T cells.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
