Insights

Nuclear Factor kappa B (NF-kappaB) promotes cell survival and suppresses programmed necrosis. Targeting the IKK/NF-kappaB pathway could enhance anti-cancer therapy efficacy by overcoming tumor cell resistance.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Cancer Research

Background:

  • Nuclear Factor kappa B (NF-kappaB) is a key transcription factor involved in cell survival.
  • NF-kappaB activation typically inhibits apoptosis by upregulating protective genes.
  • Emerging evidence shows NF-kappaB also suppresses programmed necrosis via antioxidant gene induction.

Purpose of the Study:

  • To explore the dual role of NF-kappaB in cell death pathways.
  • To investigate the potential of targeting the IKK/NF-kappaB pathway in cancer therapy.

Main Methods:

  • Literature review and analysis of existing studies on NF-kappaB function.
  • Examination of NF-kappaB's role in apoptosis and programmed necrosis.
  • Evaluation of NF-kappaB pathway as a therapeutic target in oncology.

Main Results:

  • NF-kappaB activation promotes cell survival by inhibiting apoptosis.
  • NF-kappaB also suppresses programmed necrosis by inducing antioxidant proteins.
  • Tumor cells exploit the NF-kappaB pathway to resist conventional therapies.

Conclusions:

  • The NF-kappaB pathway plays a complex role in both cell survival and death.
  • Targeting the IKK/NF-kappaB signaling pathway presents a promising strategy to enhance cancer treatment efficacy.
  • Understanding NF-kappaB's dual function is crucial for developing effective anti-cancer interventions.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
