Insights

Peroxisome proliferator-activated receptor delta (PPARdelta) is a key target in colorectal cancer progression. Inhibiting PPARdelta may offer a new strategy for cancer prevention and treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Signaling

Background:

  • Non-steroidal anti-inflammatory drugs (NSAIDs) reduce colorectal cancer risk.
  • Selective COX-2 inhibitors (coxibs) carry cardiovascular risks, necessitating identification of other colorectal cancer targets.
  • Colorectal cancer progression involves complex signaling pathway dysregulation.

Purpose of the Study:

  • To investigate the role of peroxisome proliferator-activated receptor delta (PPARdelta) in colorectal cancer progression.
  • To explore PPARdelta as a central mediator of signaling crosstalk in intestinal neoplasia.
  • To evaluate the therapeutic potential of targeting PPARdelta.

Main Methods:

  • Analysis of signaling pathways involved in colorectal cancer.
  • Investigating the interaction between PPARdelta and cancer progression mechanisms.
  • Studying the effect of PPARdelta activation on tumor cell apoptosis and VEGF signaling.

Main Results:

  • PPARdelta acts as a focal point for signaling pathway crosstalk in colorectal cancer.
  • Activation of PPARdelta promotes tumor growth by inhibiting apoptosis.
  • PPARdelta facilitates tumor progression through a VEGF autocrine signaling loop.

Conclusions:

  • PPARdelta is a critical molecular target in colorectal cancer.
  • Targeting PPARdelta may represent a novel approach for colorectal cancer prevention and treatment.
  • Understanding PPARdelta's role can guide the development of new therapeutic strategies.

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:
Inflammatory Bowel Disease II: Ulcerative Colitis01:20

Inflammatory Bowel Disease II: Ulcerative Colitis

Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
Inflammatory Bowel Disease III: Crohn's Disease01:25

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
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.

Co-activators and Co-repressors02:04

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
