Abstract:
Glioblastoma multiforme (GBM) is an aggressive and diffuse type of glioma with the lowest survival rate in patients. The recent failure of multiple treatments suggests that targeting several targets at once may be a different strategy to overcome GBM carcinogenesis. Normal function of oncogenes and tumor suppressor genes need for the preservation of regular cellular processes, so any defects in these genes' activity, operate the corresponding signaling pathways, which initiate carcinogenic processes. Long non-coding RNAs (lncRNAs) that can be found in the cytoplasm or nucleus of the cells, control the transcription and translation of genes. LncRNAs perform a variety of functions, including epigenetic alteration, protein modification and stability, transcriptional regulation, and competition for miRNA that regulate mRNA translation through sponging miRNAs. Identification of various oncogenic lncRNAs and their multiple roles in brain cancers making them potential candidates for use as glioma diagnostic, prognostic, and therapeutic targets in the future. This study highlighted multiple oncogenic lncRNAs and classified them into different signaling pathways based on the regulated target genes in glioblastoma.
Insights
Glioblastoma multiforme (GBM), a deadly brain cancer, is driven by oncogenic long non-coding RNAs (lncRNAs). Targeting these lncRNAs offers a promising new strategy for developing effective glioblastoma treatments.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Glioblastoma multiforme (GBM) is an aggressive brain cancer with poor patient survival rates.
- Current treatments have shown limited success, necessitating novel therapeutic strategies.
- Dysregulation of oncogenes and tumor suppressor genes initiates carcinogenic pathways in GBM.
Purpose of the Study:
- To identify and characterize oncogenic long non-coding RNAs (lncRNAs) involved in glioblastoma multiforme (GBM) pathogenesis.
- To explore the potential of lncRNAs as diagnostic, prognostic, and therapeutic targets for GBM.
- To classify identified oncogenic lncRNAs based on the signaling pathways they regulate.
Main Methods:
- Literature review and analysis of existing studies on lncRNAs in glioblastoma.
- Identification of key oncogenic lncRNAs implicated in GBM development and progression.
- Classification of lncRNAs according to their regulated target genes and associated signaling pathways.
Main Results:
- Multiple oncogenic lncRNAs were identified as significant contributors to GBM.
- These lncRNAs play critical roles in regulating gene transcription, translation, and epigenetic modifications.
- The study classified these oncogenic lncRNAs into distinct signaling pathways relevant to glioblastoma.
Conclusions:
- Oncogenic lncRNAs are crucial players in glioblastoma multiforme (GBM) carcinogenesis.
- lncRNAs represent promising biomarkers for GBM diagnosis and prognosis.
- Targeting oncogenic lncRNAs presents a potential novel therapeutic avenue for treating glioblastoma.
