Insights

Oncolytic viruses (OVs) show promise in cancer treatment but face challenges. Combining OVs with drugs targeting nuclear factor-kappa B (NF-κB) signaling can enhance antitumor effects and overcome tumor resistance.

Area of Science:

  • Oncology
  • Immunology
  • Virology

Background:

  • Oncolytic virotherapy is a developing cancer treatment strategy using novel anticancer drugs.
  • Oncolytic viruses (OVs) can elicit antitumor responses but struggle against tumor defenses and host limitations.
  • Nuclear factor-kappa B (NF-κB) is a key transcription factor implicated in immunity and tumorigenesis, often aberrantly activated in cancers.

Purpose of the Study:

  • To review the influence of OVs on NF-κB activation in tumor cells.
  • To highlight NF-κB signaling as a critical factor in OV-based cancer therapy.
  • To explore the potential of combining OVs with NF-κB-modulating drugs for enhanced antitumor effects.

Main Methods:

  • Literature review of studies investigating oncolytic viruses and NF-κB signaling in cancer.
  • Analysis of the interplay between OV activity and NF-κB pathway modulation.
  • Synthesis of findings on combination therapies involving OVs and NF-κB inhibitors.

Main Results:

  • OVs can modulate NF-κB signaling pathways within tumor cells.
  • Aberrant NF-κB activation is common in various cancer types, impacting therapeutic outcomes.
  • Combination therapy of OVs and NF-κB modulators shows potential for improved efficacy.

Conclusions:

  • NF-κB signaling is a crucial consideration for optimizing oncolytic virotherapy.
  • Targeting NF-κB alongside OV treatment may overcome therapeutic limitations.
  • Further research into combined OV and NF-κB-targeting strategies is warranted for effective cancer treatment.

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.

What is Cell Signaling?

Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Cell-surface Signaling01:21

Cell-surface Signaling

Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...
