Abstract:
Testicular germ cell tumors (TGCTs) are the most common tumors in adolescent and young men. Recently, genome-wide studies have made it possible to progress in understanding the molecular mechanisms underlying the development of tumors. It is becoming increasingly clear that aberrant regulation of RNA metabolism can drive tumorigenesis and influence chemotherapeutic response. Notably, the expression of non-coding RNAs as well as specific splice variants is deeply deregulated in human cancers. Since these cancer-related RNA species are considered promising diagnostic, prognostic and therapeutic targets, understanding their function in cancer development is becoming a major challenge. Here, we summarize how the different expression of RNA species repertoire, including non-coding RNAs and protein-coding splicing variants, impacts on TGCTs' onset and progression and sustains therapeutic resistance. Finally, the role of transcription-associated R-loop misregulation in the maintenance of genomic stability in TGCTs is also discussed.
Insights
Altered RNA metabolism, including non-coding RNAs and splicing variants, drives testicular germ cell tumors (TGCTs) development and resistance to chemotherapy. Understanding these RNA changes is key for TGCTs treatment.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Testicular germ cell tumors (TGCTs) are prevalent in young men.
- Genome-wide studies are advancing the understanding of tumor molecular mechanisms.
- RNA metabolism dysregulation is implicated in tumorigenesis and treatment response.
Purpose of the Study:
- To review the impact of altered RNA expression on TGCTs.
- To discuss the role of non-coding RNAs and splicing variants in TGCTs.
- To explore R-loop misregulation in TGCTs genomic stability.
Main Methods:
- Literature review of genome-wide studies.
- Analysis of RNA metabolism in cancer.
- Discussion of non-coding RNAs and splicing variants in TGCTs.
- Examination of R-loop dynamics in genomic stability.
Main Results:
- Aberrant RNA metabolism, including non-coding RNAs and splicing variants, is a hallmark of TGCTs.
- These RNA alterations contribute to TGCTs onset, progression, and therapeutic resistance.
- R-loop misregulation may affect genomic stability in TGCTs.
Conclusions:
- Altered RNA repertoire significantly impacts TGCTs pathogenesis and treatment outcomes.
- Targeting RNA species presents potential diagnostic and therapeutic strategies for TGCTs.
- Further research into R-loops is warranted for understanding TGCTs genomic maintenance.
