Abstract
- The transcription factor nuclear factor-κB (NF-κB) is a critical regulator of the immune response, inflammation, cell growth, and survival. Canonical and non-canonical pathways, two NF-κB pathways, are activated through diverse stimulators and receptors. NF-κB activity is dysregulated in various inflammation-related diseases and cancers. It was found that the persistent NF-κB activity has a major role in proliferation, apoptosis inhibition, metastasis, and cell cycle disruption in cancer cells and also the survival of cancer stem cells (CSCs) within the tumors. Therefore, suppression of the NF-κB pathway could be a promising therapeutic target for cancer therapy. Different biological inhibitors (e.g., peptides, small molecules, antisense oligonucleotides (ASOs), and antibodies (Abs)) have been demonstrated to inhibit the NF-κB pathway. Low stability in the circulation system, weak availability, and poor cellular uptake of some inhibitors limit their therapeutic applications. To address these drawbacks nanocarrier systems are often formulated and applied in drug delivery as an effective therapeutic approach. Targeted nanosystems (i.e., small molecules, peptides, Abs and Aptamers (Aps) conjugated nanocarriers), as well as smart responsive nanocarriers, can improve the efficiency of therapeutics while reducing the off-target toxicity. This review describes the NF-κB signaling pathways and mechanisms of their over-activation in tumor initiation and progression. The NF-κB inhibitors and their clinical applications are also discussed. It also overviews different nanocarriers used as robust vehicles for the delivery of NF-κB inhibitors and anti-tumor agents to improve the bioavailability of drugs and selective targeting of cancer cells to repress NF-κB activity in tumor cells. [Display omitted] • Nuclear factor-κB (NF-κB) is a critical regulator of the immune response, inflammation, cell growth, and survival. • The role of the NF-κB pathway in chronic inflammation and tumorigenesis has been approved. • Various inhibitors of the NF-κB pathway against cancers are used in clinical trials. • Advanced nanosystems are designed for targeted inhibition of the NF-κB pathway in cancers. • The future trends in the inhibition of the NF-κB illustrate the potential of advanced nanosystems for cancer therapy.
