Summary
Ten long non-coding RNAs (lncRNAs) are linked to thyroid cancer metastasis. Specific lncRNAs like AP002358.1 and LRRC52-AS1 may indicate poor prognosis and serve as diagnostic markers.
Area of Science:
- Oncology
- Molecular Biology
- Genomics
Background:
- Long non-coding RNAs (lncRNAs) are implicated in cancer development, particularly in metastasis.
- Identifying metastasis-related lncRNAs is crucial for understanding thyroid cancer progression and patient outcomes.
Purpose of the Study:
- To identify long non-coding RNAs (lncRNAs) associated with lymph node metastasis in thyroid cancer.
- To explore the clinical significance of these metastasis-related lncRNAs for patient prognosis and treatment guidance.
Main Methods:
- Utilized RNA expression and clinical data from The Cancer Genome Atlas (TCGA) and survival data from ULCAN database.
- Employed R language and SPSS software for correlation analysis between lncRNA expression and thyroid cancer lymph node metastasis.
- Screened lncRNAs significantly associated with lymph node metastasis.
Main Results:
- Identified 10 differentially expressed lncRNAs in thyroid cancer with lymph node metastasis.
- Four lncRNAs (LRRC52-AS1, AP002358.1, AC004847.1, AC254633.1) were overexpressed; six (SLC26A4-AS1, LINC01886, LINC01789, AF131216.3, AC062015.1, AL031710.1) were underexpressed.
- Elevated AP002358.1 and LRRC52-AS1 expression correlated with poor prognosis; AF131216.3 and AL031710.1 associated with progression-free survival.
Conclusions:
- These identified lncRNAs play significant roles in thyroid cancer development and progression.
- lncRNAs like AP002358.1 and LRRC52-AS1 show potential as biomarkers for predicting metastasis, clinical stage, and patient prognosis.
- Further investigation into these lncRNAs could lead to improved therapeutic strategies for thyroid cancer.

8.6K
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...

5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

8.8K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
