Introduction:
This study assessed the potential of lncRNA LINC01184 in predicting PTC progression and prognosis and its regulatory mechanism in PTC cellular processes, aiming to explore a novel biomarker for PTC.
Methods:
The study enrolled 111 PTC patients and collected paired tissue samples. Using PCR, the expression of LINC01184 was analyzed, and its association with patients' clinicopathological features and prognosis was evaluated. The regulatory effects of LINC01184 on cell growth and metastasis were assessed by CCK8 and Transwell assays.
Results:
LINC01184 was significantly downregulated in PTC, which was closely correlated with poor differentiation, advanced TNM stage, the occurrence of lymph node metastasis, and poor overall survival. In PTC cells, LINC01184 negatively regulated miR-296-3p, and its overexpression suppressed cell growth and metastasis of PTC, which was reversed by overexpressing miR-296-3p.
Conclusion:
Downregulated LINC01184 served as a biomarker for PTC. Overexpressing LINC01184 suppressed PTC cell progression via suppressing miR-296-3p.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
