LONG-NONCODING RNAs in gastroesophageal cancers

Area of Science:

• Oncology
• Molecular Biology
• Genomics

Background:

• Gastro-esophageal cancers have poor survival rates and are diagnosed late due to limited understanding of pathogenesis and lack of reliable markers.
• Advances in understanding the cancer molecular landscape offer opportunities for targeted therapies and early diagnostic biomarkers.
• Long non-coding RNAs (lncRNAs), transcripts over 200 nucleotides without protein-coding capacity, are increasingly recognized for their roles in oncogenesis.

Purpose of the Study:

• To review the role of lncRNAs in gastro-esophageal carcinogenesis.
• To assess the potential of lncRNAs as noninvasive biomarkers for early diagnosis.
• To evaluate lncRNAs in the development of next-generation targeted therapies for these cancers.

Main Methods:

• Literature review focusing on lncRNAs in gastro-esophageal cancers.
• Analysis of studies demonstrating lncRNA functions in oncogenic processes.
• Critical assessment of lncRNA potential as biomarkers and therapeutic targets.

Main Results:

• lncRNAs are functional genomic elements involved in key oncogenic processes.
• lncRNAs can modulate gene expression at multiple levels, influencing tumorigenesis.
• Emerging evidence highlights lncRNAs' significant role in gastro-esophageal carcinogenesis.

Conclusions:

• lncRNAs represent promising targets for novel therapeutic strategies in gastro-esophageal cancers.
• lncRNAs hold potential as reliable noninvasive biomarkers for early detection.
• Further research into lncRNAs could revolutionize the management of these malignancies.
