Epigenetic Regulation01:46

Epigenetic Regulation

33.7K
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation

3.9K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

What is Cell Signaling?02:03

What is Cell Signaling?

130.3K
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

54.3K
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.

Econometric Views (EViews)01:29

Econometric Views (EViews)

573
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

4.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Summary

Tumor cells escape immune surveillance by silencing the Interferon-gamma (IFN-γ) pathway. Epigenetic modifiers can restore IFN-γ signaling, enhancing anti-tumor immunity and supporting combined epigenetic and immunotherapy.

Area of Science:

  • Immunology
  • Cancer Biology
  • Epigenetics

Background:

  • Interferon-gamma (IFN-γ) is vital for immune responses and cancer surveillance.
  • Tumor cells frequently evade immune detection by disrupting IFN-γ signaling pathways.
  • Epigenetic dysregulation, including chromatin remodeling and DNA methylation, is common in cancer cells.

Purpose of the Study:

  • To investigate the role of epigenetic modifications in IFN-γ pathway dysregulation in cancer.
  • To explore the potential of epigenetic modifiers in restoring anti-tumor immunity.

Main Methods:

  • Analysis of epigenetic changes (chromatin remodeling, DNA methylation) in IFN-γ signaling pathways.
  • Examination of IFN-γ-regulated gene expression in cancer models.
  • Evaluation of epigenetic modifiers (DNMT and HDAC inhibitors) on IFN-γ pathway components and function.

Main Results:

  • Epigenetic silencing of IFN-γ pathway components and regulated genes contributes to immune escape in various cancers.
  • Epigenetic modifiers can reverse this silencing, restoring or enhancing IFN-γ signaling.
  • These modifiers show potential in boosting anti-tumor immune responses.

Conclusions:

  • Epigenetic silencing is a key mechanism for tumor immune evasion via the IFN-γ pathway.
  • Epigenetic therapies targeting DNA methylation and histone acetylation hold promise for cancer immunotherapy.
  • Combined epigenetic and immunotherapeutic approaches may enhance anti-tumor efficacy.
