Inflammation influences cancer development by altering gene networks and signaling pathways in pulmonary arterial hypertension, Crohn's disease, and ulcerative colitis. This study identifies key regulatory RNAs and pathways involved in cell adaptation to inflammation, potentially driving cancer hallmarks.
Area of Science:
- Genomics
- Molecular Biology
- Cancer Research
Background:
- Inflammation's dual role in tumorigenesis is complex, mediated by signaling pathways.
- Understanding gene expression in inflammatory diseases is crucial for cancer research.
Purpose of the Study:
- To identify regulatory networks and signaling pathways in pulmonary arterial hypertension, Crohn's disease, and ulcerative colitis.
- To explore the role of coding and non-coding RNAs in inflammation-associated cancer development.
Main Methods:
- Transcriptomic analysis of high-throughput sequencing datasets from inflammatory diseases.
- Utilized R language libraries and gene enrichment analyses for network identification.
Main Results:
- Identified disease-specific regulatory networks involving genes like IRF9, LINC01089, ZNF91, TP53TG1, VDR, DLEU1, and SATB2-AS1.
- Linked these networks to signaling pathways including MAPK, NOTCH, PPAR, and AMPK.
- Highlighted the potential role of microbiota interactions and RNA in cell plasticity and cancer hallmarks.
Conclusions:
- Transcriptomic analysis reveals key molecular players in inflammatory diseases that may contribute to cancer.
- Coding and non-coding RNAs are implicated in the adaptation of lung and gut cells to inflammatory phenotypes, promoting cancer progression.
