Insights

This review explores how interleukin-1 beta (IL-1β) and epidermal growth factor (EGF) regulate gene expression, impacting inflammation and cancer. It details their signaling pathways and links to tumorigenesis.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Oncology

Background:

  • Inflammation and cancer are complex processes involving intricate molecular signaling.
  • Interleukin-1 beta (IL-1β) and epidermal growth factor (EGF) are key mediators in these pathways.
  • Understanding their regulatory mechanisms is crucial for therapeutic development.

Purpose of the Study:

  • To elucidate the gene regulatory mechanisms of IL-1β and EGF.
  • To analyze the signaling pathways involving transcription factors NFκB and Elk-1.
  • To explore the connection between aberrant EGF signaling, inflammation, and cancer development.

Main Methods:

  • Literature review focusing on molecular mechanisms.
  • Analysis of signaling cascades initiated by IL-1β and EGF.
  • Examination of receptor-mediated cellular responses.

Main Results:

  • IL-1β and EGF activate distinct and overlapping signaling pathways.
  • Both cytokines converge on transcription factors like NFκB and Elk-1.
  • Aberrant signaling in the EGF receptor family is linked to cancer progression.

Conclusions:

  • IL-1β and EGF play critical roles in gene regulation relevant to inflammation and cancer.
  • The interplay between inflammation and EGF signaling contributes to tumorigenesis.
  • Targeting these pathways may offer therapeutic strategies for cancer.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
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.

Autocrine Signaling01:01

Autocrine Signaling

Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.
