Exploring the enigma: history, present, and future of long non-coding RNAs in cancer

Area of Science:

• Molecular Biology
• Genomics
• Cancer Research

Background:

• Long noncoding RNAs (lncRNAs) are key regulators of gene expression at transcriptional and posttranscriptional levels.
• lncRNAs exhibit tissue-specific and developmental stage-specific expression, linking them to various processes and diseases, particularly cancer.
• Despite their potential as biomarkers, the functional mechanisms of lncRNAs are not fully understood, and the extent of functional noncoding transcription in mammals is debated.

Purpose of the Study:

• To synthesize current knowledge on lncRNA biogenesis, genomic context, and roles in tumorigenesis.
• To highlight the potential of lncRNAs in cancer-targeted therapy.
• To discuss historical perspectives and recent breakthroughs in lncRNA research.

Main Methods:

• Literature review and synthesis of existing research on lncRNAs.
• Analysis of lncRNA biogenesis and genomic organization.
• Exploration of lncRNA functions in cancer development and potential therapeutic applications.

Main Results:

• lncRNAs play multifaceted roles in gene regulation and are involved in numerous biological processes and diseases, including cancer.
• Specific lncRNAs have been studied in depth, revealing emerging functional themes and mechanistic models.
• The review consolidates understanding of lncRNA roles in tumorigenesis and their therapeutic potential.

Conclusions:

• lncRNAs are critical regulators of gene expression with significant implications in cancer.
• Understanding lncRNA mechanisms is crucial for advancing cancer diagnostics, prognostics, and therapeutics.
• Further investigation into lncRNA function and biogenesis will enhance our understanding of genome evolution and clinical applications.
