Summary
Low expression of the long intergenic non-protein coding RNA (lncRNA) LINC00341, due to DNA over-methylation, correlates with poor cancer prognosis. Conversely, high LINC00341 expression indicates a better prognosis and inhibits cancer metastasis.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Long intergenic non-protein coding RNA (lncRNA) LINC00341 is a novel transcript with largely unknown functions.
- The role of LINC00341 in cancer development and progression remains to be elucidated.
Purpose of the Study:
- To investigate the expression patterns of LINC00341 in cancer patients.
- To determine the prognostic significance of LINC00341 in various cancers.
- To explore the potential role of LINC00341 in cancer metastasis.
Main Methods:
- Analysis of LINC00341 expression levels in cancer patient cohorts.
- Investigation of the correlation between DNA methylation and LINC00341 expression.
- Meta-analysis of existing studies on LINC00341 and cancer prognosis.
- Gene set enrichment analysis to identify molecular pathways associated with LINC00341.
- Large-scale multicentre data analysis.
Main Results:
- DNA over-methylation was identified as a key mechanism leading to low LINC00341 expression.
- Low LINC00341 expression was significantly associated with poor prognosis in cancer patients.
- Meta-analysis confirmed that high LINC00341 expression predicts a better prognosis.
- Evidence suggests LINC00341 plays an inhibitory role in cancer metastasis.
- Multicentre analysis validated the prognostic value of LINC00341 across diverse cancer types.
Conclusions:
- LINC00341 expression is epigenetically regulated by DNA methylation in cancer.
- LINC00341 serves as a valuable prognostic biomarker in oncology.
- LINC00341 may function as a tumor suppressor by inhibiting metastasis.

10.1K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

807
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
