Role of long noncoding RNAs in the regulation of alternative splicing in glioblastoma

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Glioblastoma multiforme (GBM) is an aggressive primary brain tumor with limited effective treatment options.
• Long noncoding RNAs (lncRNAs) are critical regulators in biological processes and cancer development.
• Alternative splicing (AS) is a key mechanism influenced by lncRNAs and frequently dysregulated in cancer.

Purpose of the Study:

• To review the role of lncRNAs in regulating alternative splicing (AS) in glioblastoma.
• To elucidate the mechanisms by which lncRNAs control AS in glioma.
• To highlight the potential of lncRNA-mediated AS as therapeutic targets for GBM.

Main Methods:

• Literature review of studies on lncRNAs, alternative splicing, and glioblastoma.
• Analysis of data from lncRNA-specific microarrays and next-generation sequencing.
• Examination of molecular pathways affected by lncRNA-regulated AS.

Main Results:

• Abnormal AS, driven by lncRNAs, contributes to GBM hallmarks like invasion, metastasis, and therapeutic resistance.
• lncRNAs modulate critical cellular signaling pathways, impacting glioma malignancy.
• Specific lncRNAs have been identified as key regulators of AS in glioblastoma.

Conclusions:

• lncRNAs are crucial players in the alternative splicing landscape of glioblastoma.
• Targeting lncRNA-mediated AS pathways presents a promising avenue for novel GBM therapies.
• Further research into lncRNA-AS interactions is essential for advancing GBM treatment strategies.
