Epigenetic regulation of papillary thyroid carcinoma by long non-coding RNAs

Area of Science:

• Endocrinology
• Molecular Biology
• Oncology

Background:

• Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy, with rising diagnoses necessitating new therapeutic strategies.
• Long non-coding RNAs (lncRNAs) are emerging as critical regulators in PTC pathogenesis.
• Studies increasingly investigate lncRNA expression in both cell models and patient samples, highlighting clinical relevance.

Purpose of the Study:

• To comprehensively review the current understanding of lncRNAs in papillary thyroid carcinoma (PTC).
• To explore the molecular mechanisms by which lncRNAs influence PTC.
• To assess the potential of lncRNAs as diagnostic and prognostic biomarkers for PTC.

Main Methods:

• Literature review of in vitro and in vivo studies on lncRNAs in PTC.
• Analysis of lncRNA expression patterns in PTC patient samples.
• Examination of lncRNA-mediated molecular pathways, including microRNA sponging and signaling pathway modulation.

Main Results:

• lncRNAs exhibit diverse roles in PTC, either promoting or suppressing tumor development.
• Key pathways targeted by lncRNAs in PTC include epithelial-mesenchymal transition, PI3K/Akt, and wnt signaling.
• lncRNAs function through mechanisms such as microRNA sponging.

Conclusions:

• lncRNAs represent a significant area of research in PTC, with substantial evidence supporting their roles in tumorigenesis.
• Further investigation into specific lncRNAs could yield novel diagnostic and prognostic biomarkers.
• Targeting lncRNAs offers potential for developing new molecularly targeted therapies for PTC.
