This study identifies LENG8-AS1 as a long non-coding RNA (lncRNA) biomarker in colorectal cancer (CRC). Upregulated LENG8-AS1 expression correlates with poor prognosis and tumor progression in CRC patients.
Area of Science:
- Oncology
- Molecular Biology
- Genomics
Background:
- Colorectal cancer (CRC) is a prevalent malignancy with distinct gene expression profiles.
- Long non-coding RNAs (lncRNAs) play a significant role in cancer development.
- Understanding lncRNA expression patterns is crucial for identifying novel biomarkers and therapeutic targets in CRC.
Purpose of the Study:
- To investigate the expression patterns of the antisense long non-coding RNA (lncRNA) LENG8-AS1 in colorectal cancer (CRC).
- To evaluate the impact of LENG8-AS1 expression on the survival outcomes of CRC patients.
- To explore the potential of LENG8-AS1 as a prognostic biomarker for CRC.
Main Methods:
- Utilized The Cancer Genome Atlas (TCGA) data and TCGA Biolinks for lncRNA candidate identification.
- Performed Cox regression analysis to correlate lncRNA expression with patient survival.
- Employed Kaplan-Meier plots for survival prediction modeling and RT-qPCR for expression validation in CRC tissues.
Main Results:
- Identified several lncRNAs, including LENG8-AS1, associated with CRC prognosis.
- Found LENG8-AS1 to be upregulated in CRC tissues and correlated with genes in lipid metabolism and angiogenesis pathways.
- Kaplan-Meier and ROC curve analyses indicated LENG8-AS1's potential as a prognostic biomarker for CRC.
Conclusions:
- LENG8-AS1 is upregulated in colorectal cancer and linked to poor patient prognosis.
- LENG8-AS1 may serve as a valuable biomarker for predicting CRC progression and patient survival outcomes.
- Further research into LENG8-AS1's role in CRC pathogenesis is warranted.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
