Abstract:
Interferon (IFN)-related DNA damage resistant signature (IRDS) genes are a subgroup of interferon-stimulated genes (ISGs) found upregulated in different cancer types, which promotes resistance to DNA damaging chemotherapy and radiotherapy. Along with briefly discussing IFNs and signalling in this review, we highlighted how different IRDS genes are affected by viruses. On the contrary, different strategies adopted to suppress a set of IRDS genes (STAT1, IRF7, OAS family, and BST2) to induce (chemo- and radiotherapy) sensitivity were deliberated. Significant biological pathways that comprise these genes were classified, along with their frequently associated genes (IFIT1/3, IFITM1, IRF7, ISG15, MX1/2 and OAS1/3/L). Major upstream regulators from the IRDS genes were identified, and different IFN types regulating these genes were outlined. Functional interfaces of IRDS proteins with DNA/RNA/ATP/GTP/NADP biomolecules featured a well-defined pharmacophore model for STAT1/IRF7-dsDNA and OAS1/OAS3/IFIH1-dsRNA complexes, as well as for the genes binding to GDP or NADP+. The Lys amino acid was found commonly interacting with the ATP phosphate group from OAS1/EIF2AK2/IFIH1 genes. Considering the premise that targeting IRDS genes mediated resistance offers an efficient strategy to resensitize tumour cells and enhances the outcome of anti-cancer treatment, this review can add some novel insights to the field.
Insights
Interferon-related DNA damage resistant signature (IRDS) genes promote cancer resistance to therapy. Targeting these IRDS genes may resensitize tumors, improving anti-cancer treatment outcomes.
Area of Science:
- Oncology
- Immunology
- Molecular Biology
Background:
- Interferon-related DNA damage resistant signature (IRDS) genes are upregulated in cancers, conferring resistance to chemotherapy and radiotherapy.
- These genes are part of the larger interferon-stimulated genes (ISGs) family and are influenced by viral infections.
Purpose of the Study:
- To review the role of IRDS genes in cancer therapy resistance.
- To explore strategies for targeting IRDS genes to enhance treatment sensitivity.
- To identify upstream regulators and functional interactions of IRDS genes.
Main Methods:
- Literature review of IRDS genes, their regulation by interferons (IFNs), and their association with biological pathways.
- Analysis of viral effects on IRDS genes and strategies to suppress them.
- Identification of pharmacophore models for IRDS protein interactions with biomolecules.
Main Results:
- IRDS genes, including STAT1, IRF7, OAS family, and BST2, contribute to chemo- and radioresistance.
- Specific IRDS genes are frequently associated with pathways involving IFIT1/3, IFITM1, ISG15, MX1/2, and OAS1/3/L.
- Pharmacophore models reveal interactions of IRDS proteins with DNA, RNA, GDP, and NADP+, with Lysine commonly involved in ATP binding.
Conclusions:
- Targeting IRDS genes represents a promising strategy to overcome cancer therapy resistance.
- Understanding IRDS gene function and interactions can lead to novel therapeutic approaches for cancer treatment.
