Abstract

Insights

Activating peroxisome proliferator-activated receptor alpha (PPARα) reprograms oral tumor metabolism. Upregulating the RNA degradation pathway via PPARα activation presents a novel therapeutic strategy for oral cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Peroxisome proliferator-activated receptor alpha (PPARα) activation influences tumor metabolism.
  • PPARα shows potential in treating oral tumorigenesis.

Purpose of the Study:

  • To investigate functional pathways affected by PPARα activation in oral cancer.
  • To explore the anticancer mechanisms of PPARα in oral cancer cells.

Main Methods:

  • Utilized a pathway-based strategy for analysis.
  • Employed next-generation sequencing (NGS) and bioinformatic approaches.
  • Conducted Gene Ontology (GO) and KEGG enrichment analysis.

Main Results:

  • PPARα activation led to 3919 upregulated and 1060 downregulated genes.
  • Key affected pathways include proteasomal, mRNA surveillance, spliceosomal, RNA transport, and RNA degradation.
  • Identified 13 upregulated genes in the RNA degradation pathway, including exosome, TRAMP, CCR4-NOT, and Ski complex components.

Conclusions:

  • PPARα activation upregulates the RNA degradation pathway in oral cancer cells.
  • This suggests a potential new therapeutic strategy for oral cancer treatment.

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:

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
