Abstract

Insights

Oligodeoxynucleotides (ODN) inhibit nuclear factor-kappaB (NF-kappaB) translocation and binding in THP-1 cells. This suppression of NF-kappaB activity reduces inflammatory gene expression, offering a potential treatment for acute pancreatitis.

Area of Science:

  • Molecular Biology
  • Immunology

Context:

  • Nuclear factor-kappaB (NF-kappaB) plays a crucial role in inflammatory responses.
  • THP-1 cells are a human monocytic cell line commonly used in inflammation research.
  • Lipopolysaccharide (LPS) is a potent activator of NF-kappaB.

Purpose:

  • To investigate the inhibitory effect of oligodeoxynucleotides (ODN) on NF-kappaB nuclear translocation and binding activity.
  • To assess the impact of ODN on NF-kappaB-mediated gene expression in LPS-stimulated THP-1 cells.

Summary:

  • Oligodeoxynucleotides (ODN) were introduced into THP-1 cells, which were then stimulated with LPS.
  • Immunocytochemistry, EMSA, and RT-PCR demonstrated that ODN inhibited NF-kappaB nuclear translocation and binding.
  • ODN treatment suppressed the mRNA expression of TNF-alpha, an inflammatory factor associated with NF-kappaB.

Impact:

  • ODN effectively inhibits NF-kappaB activation in THP-1 cells.
  • Suppression of NF-kappaB and related inflammatory gene transcription suggests ODN as a potential therapeutic strategy.
  • This research provides a novel approach for the clinical treatment of acute pancreatitis.

Eukaryotic Transcription Inhibitors01:52

Eukaryotic Transcription Inhibitors

Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
Eukaryotic transcription inhibitors usually contain two distinct domains, a DNA...
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.

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Inhibition of CDK Activity02:34

Inhibition of CDK Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
