Insights

The non-canonical NF-κB pathway is crucial in diseases like cancer. Inhibiting its key molecule, NF-κB inducing kinase (NIK), offers a promising therapeutic strategy for various cancers and inflammatory conditions.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Oncology

Background:

  • The non-canonical nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway regulates critical genes in various biological processes.
  • Dysregulation of this pathway is implicated in autoimmune diseases, inflammation, and cancers.
  • Despite its significance, no drugs specifically target NF-κB inducing kinase (NIK), a key mediator.

Purpose of the Study:

  • To review the role of the non-canonical NF-κB pathway in normal physiology and cancer.
  • To discuss pharmacological strategies for modulating NIK and downstream targets.
  • To highlight NIK inhibition as a potential cancer therapeutic strategy.

Main Methods:

  • Literature review of studies on non-canonical NF-κB signaling.
  • Analysis of the pathway's involvement in physiological and pathological conditions.
  • Exploration of existing and potential therapeutic interventions.

Main Results:

  • The non-canonical NF-κB pathway plays a significant role in cellular functions and disease pathogenesis.
  • NIK is a critical signaling molecule with therapeutic potential, particularly in oncology.
  • Several downstream targets within the pathway are also amenable to pharmacological modulation.

Conclusions:

  • Targeting the non-canonical NF-κB pathway, especially NIK, presents a viable therapeutic avenue for cancers and inflammatory diseases.
  • Further research into pharmacological strategies can lead to novel treatments.
  • Modulating this pathway holds promise for managing various human ailments.

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.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
