Pseudogenes in gastric cancer pathogenesis: a review article
Briefings in Functional Genomics
|May 2, 2017
Summary
Pseudogenes, once dismissed as junk DNA, are now recognized for their significant roles in cancer. These genetic elements are emerging as key modulators in the development of gastric cancer.
Area of Science:
- Genetics
- Oncology
- Molecular Biology
Background:
- Gastric cancer (GC) is a global health concern, ranking as the fifth most common malignancy and third leading cause of cancer death worldwide.
- Pseudogenes were historically considered nonfunctional "junk DNA" with no contribution to organismal survival.
- Recent research indicates pseudogenes possess diverse biological activities relevant to human cancers.
Purpose of the Study:
- To explore the multifaceted roles of pseudogenes in the pathogenesis of gastric cancer.
- To highlight pseudogenes as potential modulators of gene expression in cancer development.
Main Methods:
- Literature review of recent advancements in pseudogene research.
- Analysis of pseudogene functions in the context of gastric adenocarcinoma.
Main Results:
- Pseudogenes exhibit a broad spectrum of activities in human cancers, including gastric cancer.
- These functions can be either dependent on or independent of their parental genes.
- Pseudogenes are implicated as crucial players in the molecular mechanisms underlying gastric cancer.
Conclusions:
- Pseudogenes are emerging as a significant class of gene expression modulators.
- Their involvement in gastric adenocarcinoma pathogenesis underscores their importance in cancer research.
- Further investigation into pseudogene functions may reveal novel therapeutic targets for gastric cancer.
